Rationale for this Study 
Triple-negative breast cancer (TNBC) is a heterogeneous disease with limited 
treatment options and very poor prognosis for metastatic disease, with median 
progression-free survival with chemotherapy ranging from 2.5 to 4 months. In addition, 
there is limited effective targeted therapy in patients with metastatic TNBC with the 
exception of tumors with germline BRCA mutation, which highlights TNBC as an area 
of unmet need.  
 
The Cancer Genome Atlas (TCGA) analysis demonstrated that the most frequent loss-
of-function and gain-of-function alterations in TNBC involve genes associated with 
DNA damage repair and phosphatidylinositol 3-kinase (PI3K) signaling pathway, 
including the axis of PI3K-mTOR-Akt /PTEN loss. Non-basal subtypes (i.e. LAR, M 
and MSL) demonstrated relatively high PIK3CA –activating mutations and exhibit 
sensitivity to PI3K inhibitors in vitro. In addition, the mTOR inhibitor everolimus has 
shown activity in basal-like TNBC. Nevertheless, use of PI3K inhibitors as single agent 
therapy has proven minimally effective secondary to multiple feedback mechanisms. 
Combination therapies with chemotherapy agents have shown synergy, and we are 
conducting a phase I/IB study combining eribulin with everolimus in metastatic TNBC 
as one such strategy (NCT02120469).  
 
Another strategy utilizing this pathway revolves around AKT. Ipatasertib (GDC-0068) 
is a novel selective ATP-competitive small-molecule inhibitor of AKT that preferentially 
targets active phosphorylated Akt (pAkt) and is potent in cell lines with evidence of Akt 
activation. Ipatasertib displays synergy when combined with taxanes or other 
chemotherapeutic agents (Gemcitabine, platinum, 5-FU, doxorubicin(1), paclitaxel) in 
vitro. In a phase I study, ipatasertib was well-tolerated with a maximum tolerated dose 
(MTD) of 600 mg daily dosed 21 days on and 7 days off. The most common adverse 
events were grade 1–2 diarrhea, nausea, asthenia, and hyperglycemia. In the Phase 
Ib study, ipatasertib combined with docetaxel or mFOLFOX6, was well-tolerated with 
evidence of anti-tumor activity and MTD of 600mg daily. Currently, the combination of 
paclitaxel (80mg/m2, days 1, 8,15 every 4 weeks) and ipatasertib (400mg daily 3 
weeks on and 1 week off) are being studied in both the metastatic setting 
(NCT02162719) and the neoadjuvant setting (NCT02301988) in TNBC. In the LOTUS 
trial, combination of paclitaxel 80mg/m2 (days 1, 8 & 15) and ipatasertib 400mg po 
days 1-21 every 28 days has shown modestly-improved PFS. The combination 
regimen was well-tolerated with 23% of grade ≥3 diarrhea and 18% grade 3

neutropenia.  
 
The combination of ipatasertib with single DNA-damaging agents is another potential 
strategy for synergy. DNA-damaging agents such as platinum drugs (cisplatin and 
carboplatin) are active in TNBC. In the randomized TNT trial, single-agent carboplatin 
was compared to single-agent docetaxel in patients with metastatic TNBC. Patients 
with TNBC and germline BRCA 1/2 mutations were found to have a higher response 
rate and longer progression-free survival rates favoring carboplatin over docetaxel. 
Weekly paclitaxel (100mg/m2) was combined with weekly carboplatin AUC 2, days 1, 
8, and 15 on a 4 week schedule in a cohort of advanced breast cancer patients. The 
regimen was effective with a response rate of 62% and was well tolerated with a grade 
3/4 neutropenia rate of 35%. Other grade 3/4 toxicities included neuropathy (11%), 
infection (6%), weakness (6%), anemia (5%), and paresthesia (3%). This study 
showed that weekly carboplatin/ paclitaxel produces response rates comparable with 
those seen with the q3w schedule, but with a more favorable toxicity profile. A high 
proportion of TNBC tumors exhibit BRCAness-like status, which indicate these 
tumors are highly sensitive to platinum salts.  
 
In the patient-derived xenograft model of mTNBC, carboplatin and ipatasertib were 
synergistic in tumor suppression (unpublished data). Based on this evidence, we 
hypothesize that carboplatin or carboplatin/paclitaxel plus the Akt inhibitor ipatasertib 
will have a synergistic effect in TNBC. Hence arms (A and B) of this clinical trial are 
designed to determine the dose and safety of the doublet ipatasertib/carboplatin and 
triplet combination ipatasertib/carboplatin/paclitaxel and obtain initial evidence of 
efficacy. 
 
The Impassion130 study demonstrated the addition of atezolizumab (anti-PD-L1) to 
nab-paclitaxel improved PFS and OS outcomes in PD-L1 positive mTNBC in the first 
line setting. It remains unknown whether non-taxane chemo + anti-PD-1/L1 will be 
beneficial in mTNBC. CREATE-X study that supports the use of adjuvant capecitabine 
for patients who have residual disease after standard neoadjuvant chemotherapy. 
Given these data, as well as promising data supporting the use of immune checkpoint 
inhibition (ICI) in TNBC, there is a strong interest in testing the combination of an ICI in 
combination with capecitabine. In a phase IB study, the combination of ipatasertib, 
atezolizumab and paclitaxel or nab-paclitaxel showed a promising response rate of 
73% in a cohort of 26 patients with unresectable, locally advanced/metastatic TNBCs 
previously untreated in the metastatic setting.  Interestingly, responses were high 
irrespective of PD-L1 status or PI3K/AKT/PTEN alteration status(2).In the third arm of 
this study, arm C, we aim to test the combination of ipatasertib, capecitabine and 
atezolizumab in patients with mTNBC. 
 
As a result, in the current trial, we will study the following combinations in patients with 
metastatic TNBCs: carboplatin+ ipatasertib, carboplatin + paclitaxel + ipatasertib, 
capecitabine + atezolizumab + ipatasertib. The primary objective is to determine the 
recommended starting dose for each combination, further evaluate the safety of the 
combinations and obtain initial evidence of activity . In addition, blood and tumor 
samples are collected for correlative analysis in order to identify potential biomarkers 
associated with response to therapy.

IV infusion on days 1,8,15 of every 28 day cycles for Triplet Arm A.  
Carboplatin will be given at a starting dose of AUC 2 on days 1, 8, 15 every 28 days 
for doublet Arm B. 
Arm C: 
Ipatasertib will be given at a starting dose of 300 mg oral daily for 21 days on 7 days 
off, every 28 days.Capecitibine will be given at a starting dose of 750 mg/m2, 1 week 
on 1 week off x 2. 
Atezolizumab will be given at a starting dose of 840 mg IV d 1 and 15. Every 28 days 
is a cycle. 
 
Clinical Observations and Tests to be Performed 
Patients who fulfill the eligibility criteria will undergo the full informed consent process. 
Prior to starting treatment, all subjects will undergo history and physical exam, and 
laboratory studies including CBC, diff, chemistry, liver function tests, INR/PTT, and 
viral serology.  
 
Baseline disease will be documented with brain MRI with contrast, bone scan and CT 
scan of chest, abdomen and pelvis, or PET-CT as long as there is a diagnostic CT 
component (within 35 days prior to starting treatment).  
 
All subjects will have cardiac function evaluation (within 30 days prior to starting 
treatment) using an EKG. 
 
CBC with differential and comprehensive serum chemistry panel will be performed on 
Day 1, 8, 15 of each 4-week cycle and on chemotherapy infusion days through the 
duration of the study. The study team will monitor the CBCs for dose limiting toxicities 
(DLTs) evaluation during the first 4 weeks of the study.  
 
Restaging imaging (CT, bone scan if indicated) will be repeated every 12 weeks (+/-
7days). At screening, staging imaging within 35 days (5 weeks) of study entry is 
allowed. Reading and comparison of two prior staging imaging (3 month and 6 month 
prior to study entry) are required to document SD per RECIST version 1.1.  
 

 
 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
9 
During screening, brain imaging will be performed in subjects with known untreated or 
unstable brain metastases (such subjects also need records of brain imaging 
performed within the last 3 months prior to screening to establish stability). 
 
Tumor biopsies will be obtained prior to study initiation, at Cycle 2 day 1 (C2D1) and 
at end of study. If fresh tumor biopsy is not feasible at study entry, archived formalin-
fixated paraffin-embedded tumor tissue procured within 6 months of study entry must 
be obtained. At least 20 x 5um cut of unstained slides with adequate tumor volume 
must be submitted to study team at time of patient registration. When a core needle 
biopsy is used, a minimum of 4 core biopsy samples with a minimum 18 gauge needle 
is required. 
 
Peripheral blood samples will be obtained at baseline (Day 1 cycle 1, D1C1), as well 
as Day 1 of cycles 2, 4 and end-of-treatment visit. Three tubes (1 x 10 ml green-top, 1 
x 10 ml Streck tube (Cell-free DNA BCT®) and 1 x 10 ml lavender-top) of blood will be 
collected and delivered to the correlative study PI’s laboratory. Peripheral blood or 
biopsy sample can be taken at end of treatment if patient was off trial due to reasons 
other than disease progression. 
 
Stool sample will be collected at baseline, C4D1 and end-of-treatment visit for 
microbiome and calprotectin analysis. 
 
Patient reported outcome measured by EORTC QLQ-C30 questionnaire will be 
completed by patient on C1D1, then every 3 month at the tumor assessment visit, and 
up to 3 and 6 months after radiological disease progression. The questionnaire should 
be completed before the patient receives any information on disease status and prior 
to the performance of non-PRO assessments and the administration of study 
treatment.  
 
 
Statistical Considerations 
Statistical Design for Arm A and B: This is a Phase I trial of ipatasertib plus either 
carboplatin or carboplatin/ paclitaxel in patients with metastatic TNBC.   
 
Phase: I/IB 
Purpose: Safety and Initial Evidence of Efficacy 
 
The combination of paclitaxel and ipatasertib have been well-tolerated and the 
recommended phase II dose is ipatasertib 400mg po daily 3 weeks on/1 week off, 
paclitaxel 80mg/m2 days 1, 8,15 of every 4 week cycle. Two dosing regimens will be 
tested in this study. In triplet schedule A, carboplatin AUC 2, paclitaxel 80mg/m2 will 
be added on day 1, 8 and 15 of every 4 weeks cycle while patients receive ipatasertib 
of 400mg daily. In doublet schedule B, carboplatin AUC2 on days 1, 8, 15 every 28 
days will be added to ipatasertib 400mg daily continuous dosing. 
 
Primary Objective: 
To determine the recommended Phase II dose of ipatasertib plus either carboplatin or 
carboplatin/paclitaxel in patients with metastatic TNBC  
 
Secondary Objectives: 

 
 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
10 
1. 
To confirm the recommended Phase II dose safety in an expanded cohort. 
2. 
To evaluate progression-free survival, overall survival and response. 
3. 
Further describe the cumulative toxicities of the combinations 
4.   To evaluate patient’s quality of life (QOL) 
 
Exploratory Objectives:  
Preliminary data suggests a better response to ipatasertib in patients with PTEN loss/ 
PIK3CA-Akt mutated breast tumors. TNBC sub-typing will be performed through 
mRNA profiling. DNA exome-sequencing via NGS will be used for detecting genomic 
alterations. These genomic alterations will be associated with clinical responses. The 
frequency and role of PTEN loss, PIK3CA-Akt pathway status, and BRCA mutation 
status will be tested as correlatives. The association of stool microbiome and 
calprotectin with diarrhea will also be studied. 
 
Phase I/Ib Design: 
We will use the Phase I Queue (IQ) 3+3 design that ensures patient risk does not 
exceed the maximum risk permitted in the traditional 3+3 design, while enabling fewer 
study holds and permits the PI to proceed with a more rapid completion of the Phase I 
study. A variety of 3-at-risk designs have been conducted, including NCI/CTEP 
studies based on the 3+3 risk constraints (NCT02568553, NCT01567709). This 
method has been shown (JSM 2016) to reduce study duration by an average of 
approximately 23% for a typical Phase I study, with a median increase in the number 
of patients of 1-4, while reducing the number of patients turned away due to lack of 
slots. The details of the design are described in section 3. (see Phase I Queue (IQ) 
3+3 table which also has a side-by-side comparison with the classic 3+3 design). 
 
To confirm the recommended Phase II dose obtained from the dose escalation, and 
for an initial assessment of response, correlatives and PFS estimates, we will enroll an 
additional cohort of patients until the number treated and evaluable for DLT 
considerations at the recommended phase II dose is 14 patients for the doublet (Arm 
B) and for the triplet Arm (Arm A) 
  
All eligible patients who start treatment at the recommended Phase II dose will be 
considered in the calculation of the response rate. 
 
Sample size for Arm A and B: Expected sample size (if level 1 is well-tolerated) is 14 
patients for both the doublet and triplet, for an expected total sample-size of 28 
patients. Additional cohorts of 6-8 patients will be required if lower doses are 
necessary (e.g. level 1 is not well-tolerated) for each Arm.   
 
Statistical Design for Arm C: 
Clinical Statistics: For the safety-lead in, a 3 at risk design will be utilized to assess 
toxicity for the combination therapy as per Table C in Protocol 18496. The DLT period 
is 1-cycle (28 days).  
Each participant will remain on the dosing level according to the escalation dose level 
they were enrolled in, and intra-dose level escalations will not be allowed, even if the 
MTD is defined at a higher dose level. Rules for escalation are given in Table C. If a 
patient comes off study in the first 28 days for any reason outside of toxicity (unrelated

AE, withdrawal of consent, progression of disease etc), this patient will not be 
considered as evaluable for DLT and this patient should be replaced.  
When a maximum tolerable dose level has been defined by the dose escalation 
portion of the study, and the recommended phase 2 dose (RP2D not to exceed the 
MTD) has been selected,  additional patients will be accrued to confirm the tolerability 
of the regimen.  Specifically, at least 12 patients will be treated at the RP2D to confirm 
tolerability.  Additional patients (beyond the 12 at the RP2D can be accrued if the total 
number of patients accrued does not exceed 21 patients With 12 patients, any specific 
severe toxicity with 20% incidence will be observed with 93% probability.  
Secondary Objectives: Clinical activity will be described based on the secondary 
objectives, with a description of the activity based on PD-L1 status.  Survival 
endpoints will be evaluated using Kaplan-Meier methods.  Other correlative studies 
are considered exploratory in the context of this limited Phase I study; however, when 
the sample size is 12, a single group t-test with a 0.050 one-sided significance level 
will have 80% power to detect an effect size of 0.766.

BACKGROUND 
1.1 
BACKGROUND ON TRIPLE-NEGATIVE BREAST CANCER 
Globally, breast cancer is the second most common invasive malignancy and the most 
common cause of cancer-related mortality in women, with a 5-year survival rate 
following metastatic diagnosis of approximately 15% (Jemal et al. 2011; Ferlay et al. 
2015).  
Triple-negative breast cancer (TNBC) accounts for approximately 20% of all breast 
cancers and is defined by the absence of immunostaining (<1%) for estrogen receptor 
(ER), progesterone receptor (PgR), and non-amplified human epidermal growth factor 
receptor 2 (HER2) expression per American Society of Clinical Oncology (ASCO) and 
College of American Pathologists (CAP) guidelines (ASCO/CAP 2010, 2013). Patients 
with metastatic TNBC exhibit a particularly poor clinical outcome, generally with rapid 
progression and a median overall survival (OS) rate of approximately 16 months 
(Rodler et al. 2010; Miles et al. 2013). Although TNBC may respond to chemotherapy, 
including taxanes, there are no approved first-line targeted therapies for patients with 
this specific subtype of breast cancer. Because of an increase in toxicity and little 
survival benefit with combination chemotherapy, treatment with sequential single agents 
is generally preferred (Cardoso et al. 2017; NCCN 2017). Paclitaxel is considered an 
appropriate first-line regimen, with a median progression-free survival (PFS) of 
approximately 6 months in patients with TNBC (Miles et al. 2013; Miles et al. 2017). 
There is a pressing need for clinically active agents for the triple-negative subtype of 
metastatic breast cancer. 
PI3K/Akt Pathway in Breast Cancer 
The phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway is more frequently 
activated by genomic aberrations than any other signaling pathway in cancer (LoRusso 
2016). The most common genetic alterations in this pathway are activating mutations of 
phosphatidylinositol-4, 5−bisphosphate 3-kinase, catalytic subunit, alpha (PIK3CA), 
loss-of-function alterations of the tumor suppressor phosphatase and tensin homolog 
(PTEN), deregulation of receptor tyrosine kinase signaling, and amplification and 
mutations of receptor tyrosine kinases (Cancer Genome Atlas Network 2012; Millis et al. 
2015). Alterations in Akt itself, including amplification and overexpression of individual 
Akt isoforms, as well as activating mutations in Akt, have been identified in a subset of 
human cancers (Bellacosa et al. 2005; Brugge et al. 2007; Tokunaga et al. 2008). All of 
these mechanisms of pathway activation ultimately funnel through Akt as the central 
node that drives cell survival, growth, proliferation, angiogenesis, metabolism, and 
migration (Manning and Cantley 2007).  
Large-scale comprehensive genomic analyses have characterized the heterogeneous 
nature of TNBC, including a subgroup with a PI3K/Akt pathway activation signature 
characterized by PIK3CA or AKT1 activating mutations and PTEN alterations (Cancer 
Genome Atlas Network 2012). Overall, PIK3CA/AKT1/PTEN-altered tumors are

22 
frequently observed in breast cancer, and are reported in approximately 35% of patients 
with TNBC and in approximately 50% of HR+/HER2− breast cancers (Cancer Genome 
Atlas Network, 2012).  
To date, the relationship between PI3K/Akt pathway activation and prognosis in early 
breast cancer is mixed, with some data demonstrating association with favorable 
outcomes, some data with poor prognosis, and a number of studies showing insignificant 
results (Yang et al. 2016). Information demonstrating significant differences in the 
prevalence of these gene alterations between primary and metastatic tumor tissues is 
limited, while enrichment in metastatic patients is probable (Millis et al. 2015).  
 
1.2 
BACKGROUND ON IPATASERTIB 
Ipatasertib is a potent, highly selective small-molecule inhibitor of all three isoforms of 
the serine/threonine kinase Akt. Ipatasertib binds to the activated conformation of Akt and 
is ATP competitive. Ipatasertib binding inhibits the kinase activity of Akt and suppresses 
the phosphorylation of its direct substrates, including PRAS40, and additional 
downstream targets, such as S6 ribosomal protein (S6RP), resulting in G1 arrest and/or 
apoptosis in human cancer cells (Lin et al. 2012). In clinical tumor samples, robust Akt 
pathway inhibition by ipatasertib can be achieved at clinically relevant doses (Yan et al. 
2013). 
Upregulation of Akt signaling (whether intrinsic or induced following chemotherapy) 
represents a potentially important survival pathway in response to genotoxic/mitotic 
stress (Xu et al. 2012). Activation of Akt signaling following chemotherapy (including 
taxanes) may promote cell survival and chemoresistance across several cancer models, 
including breast cancer (Clark et al. 2002). Conversely, inhibition of the PI3K/Akt 
pathway in diverse cancers leads to radiosensitization and/or chemosensitization 
(Brognard et al. 2001; Solit et al. 2003; Wallin et al. 2010). 
In nonclinical models with high levels of phosphorylated Akt or PI3K/Akt pathway activity 
(i.e., PIK3CA mutation, PTEN alterations), sensitivity to ipatasertib has been observed 
across different tumor models, including breast cancers (Lin et al. 2013). Additionally, 
ipatasertib plus microtubule inhibitors or DNA-damaging chemotherapeutic agents 
showed a clear advantage over respective single-agent treatment in preclinical models 
(refer to the Ipatasertib Investigator’s Brochure for further information).  
Based on the scientific rationale that PI3K/Akt blockade attenuates survival signals 
associated with mitotic stress from treatment with microtubule inhibitors and the high 
prevalence of PI3K/Akt pathway activation signatures in TNBC and in HR+/HER2− 
tumors (Cancer Genome Atlas Network, 2012), clinical trials evaluating the preliminary 
safety and efficacy of the combination of ipatasertib and paclitaxel in patients with breast 
cancer have been conducted. These trials include a Phase Ib study with an expansion

cohort of patients with HER2− breast cancer (Study PAM4983g, Arm C) and a 
randomized Phase II study (GO29227, LOTUS) comparing ipatasertib + paclitaxel versus 
placebo + paclitaxel as first-line treatment for patients with inoperable locally advanced or 
metastatic TNBC.  
In the Phase Ib study PAM4983g, 3 of the 15 patients (20%) with breast cancer 
remained progression free for > 6 months (HR+/HER2−: n = 2; TNBC: n = 1), and 4 partial 
responses included patients who had prior exposure to paclitaxel or investigational PI3K 
inhibitors (HR+/HER2−: n = 2; TNBC: n = 2). 
In the randomized Phase II study GO29227, one of the objectives was to investigate the 
added benefit of ipatasertib to paclitaxel in the subgroup of patients with 
PIK3CA/AKT1/PTEN-altered tumors. Results from this study showed improvement in 
median PFS in the intent-to-treat (ITT) population (hazard ratio = 0.60; 6.2 months in the 
ipatasertib arm compared with 4.9 months in the control arm); and more pronouncedly in 
the pre-specified patient population with PIK3CA/AKT1/PTEN-altered tumors (hazard 
ratio = 0.44; 9 months vs. 4.9 months). 
Refer to the Ipatasertib Investigator's Brochure for details on nonclinical and clinical 
studies, including single-agent activities in the Phase I study (PAM4743g). 
 
1.3 
BACKGROUND ON CARBOPLATIN 
DNA-damaging agents such as platinum drugs (cisplatin and carboplatin) are active in 
TNBC. The randomized TNT trial, single-agent carboplatin was compared to single-
agent docetaxel in patients with metastatic TNBC. Patients with TNBC and germline 
BRCA1/2 mutations were found to have a higher response rate and longer progress-free 
survival rates favoring carboplatin over docetaxel (Tutt et al. 2015). Weekly paclitaxel 
(100mg/m2) was combined with weekly carboplatin AUC 2, days 1, 8, and 15 on a 4 
week schedule in a cohort of advanced breast cancer patient. The regimen was effective 
with a response rate of 62% and well tolerated with a grade ¾ neutropenia rate of 35%. 
Other grade 3/4 toxicities included neuropathy (11%), infection (6%), weakness (6%), 
anemia (5%), and paresthesia (3%) (Loesch et al. 2002). This study showed that weekly 
carboplatin/ paclitaxel produces response rates comparable with those seen with the 
q3w schedule, but with a more favorable toxicity profile (Loesch et al. 2002). A high 
proportion of TNBC tumor exhibit BRCAness-like status, which indicate these tumors 
are highly sensitive to platinum salts.  
 
1.4 
STUDY RATIONALE AND BENEFIT-RISK ASSESSMENT FOR 
ARM A AND B 
Metastatic breast cancer remains an incurable disease. For patients with locally 
advanced and metastatic TNBC, clinical outcome is particularly poor, generally with 
rapid progression and a median OS of approximately 16 months (Rodler et al. 2010; 

Page 24 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
24 
Miles et al. 2013). For patients with HR+/HER2− breast cancer who are not appropriate 
candidates for endocrine therapy, OS with first-line chemotherapy with weekly 
single-agent paclitaxel is approximately 28 months (Miles et al. 2013; Miles et al. 2017).  
Results of the Phase II randomized Study GO29227 demonstrated that adding 
ipatasertib to paclitaxel as first-line therapy for inoperable locally advanced or metastatic 
TNBC improves PFS in the ITT and in PTEN-low populations; the PFS improvement was 
more pronounced in patients with PIK3CA/AKT1/PTEN-altered tumors identified with the 
FoundationOne next-generation sequencing (NGS) assay (representing approximately 
40% of the randomized patients in this setting). The use of PIK3CA/AKT1/PTEN-
alteration status as a predictive biomarker for response to the combination of ipatasertib 
and paclitaxel in metastatic TNBC is further supported by the pronounced PFS 
improvement over the complementary population of patients with PIK3CA/AKT1/PTEN 
non-altered tumors. 
The clinical safety profile of ipatasertib as a single agent in the Phase Ia 
study (PAM4743g) and in combination with paclitaxel in the Phase Ib (PAM4983g) and 
Phase II (GO29227) studies supports continued development in metastatic breast 
cancer. As a single agent, ipatasertib has a predictable pharmacokinetic (PK) profile with 
a half-life of approximately 48 hours and significantly downregulates the PI3K/Akt 
pathway at doses ≥ 200 mg. In Study GO29227, the adverse effects of ipatasertib plus 
paclitaxel in metastatic TNBC were consistent with previous experiences of ipatasertib 
and of paclitaxel, most notably ipatasertib-related gastrointestinal toxicities that are 
manageable and reversible. Common adverse events with a ≥ 10% higher incidence in 
the ipatasertib arm than in the placebo arm were diarrhea, nausea, asthenia, and 
peripheral sensory neuropathy. Common Grade ≥ 3 adverse events included diarrhea, 
neutropenia, neutrophil count decreased, and fatigue. When grouping the adverse event 
preferred terms with similar medical concepts, asthenia/fatigue and peripheral 
neuropathy were not significantly different between the two arms (refer to the Ipatasertib 
Investigator’s Brochure for detailed safety information). 
In Study GO29227, diarrhea was more common in the ipatasertib arm compared with 
the placebo arm (93% vs. 19%); however, the majority of cases were low grade. The 
onset of diarrhea was most common within the first cycle; late onset diarrhea was rare, 
and no cases of colitis were reported. Diarrhea generally responded to loperamide 
treatment and to ipatasertib dose holds and dose reductions when resuming treatment; 
limited (only 3%) discontinuation of ipatasertib treatment due to diarrhea was reported. 
Despite the high frequency of diarrhea in the ipatasertib arm, the median relative dose 
intensity of both ipatasertib and paclitaxel approached 100% and was comparable in the 
ipatasertib and placebo arms. 
In current studies, to improve diarrhea management and patient experiences, 
anti-diarrhea prophylaxis (loperamide) has been mandated for the first cycle for all 
patients (where allowed by local guidance) and implemented subsequently as clinically 

Page 25 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
25 
indicated. Patients are being monitored for early signs of diarrhea symptoms, and 
investigators will be provided with comprehensive management guidelines for study 
treatment−related symptoms or potential risks.  
Based on the efficacy of carboplatin in TNBC, and prior Phase II data (GO29227) in 
patients with TNBC support the addition of ipatasertib to carboplatin treatment in patients 
with metastatic TNBC. Our preclinical data in patient derived xenograft model of 
metastatic TNBC, carboplatin and ipatasertib were synergistic in tumor suppression 
(Yuan et al. unpublished data). Based on these evidence, we hypothesize that 
carboplatin or carboplatin/paclitaxel plus the Akt inhibitor ipatasertib will have a 
synergistic effect in TNBC. Hence this clinical trial is designed to test the safety of the 
doublet and triplet combination and obtain initial evidence of efficacy. The combination of 
ipatasertib and paclitaxel has been generally well tolerated and comprehensive 
guidelines for management of anticipated treatment-related symptoms will be 
incorporated into this protocol building upon previous clinical trial experience. 
Preliminary data suggests a better response to ipatasertib in patients with 
PIK3CA/AKT1/PTEN altered breast tumors. DNA targeted exome-sequencing will be 
used for detecting genomic alterations. TNBC sub-typing will be performed through 
mRNA profiling. These genomic alterations will be associated with clinical responses.  
 
This trial will enroll patients with metastatic triple negative breast cancer. Given the 
relatively poor prognosis and limited treatment options for these patients, this population 
is considered appropriate for trials of novel therapeutic candidates. The benefit-risk ratio 
for ipatasertib in combination with carboplatin or carboplatin/ paclitaxel is expected to be 
acceptable in this setting. 
1.5 Background on Arm C  
 
Capecitabine and Immune Checkpoint Inhibitor: The Impassion130 study demonstrated the 
addition of immune checkpoint inhibitor atezolizumab (anti-PD-L1) to nab-paclitaxel improved 
PFS in PD-L1 positive mTNBC in the first line setting.(3)  It remains unknown whether non-
taxane chemo + anti-PD-1/L1 will be beneficial in mTNBC. In the curative setting, evidence has 
emerged from the CREATE-X study that supports the use of adjuvant capecitabine for patients 
who have residual disease after standard neoadjuvant chemotherapy (containing anthracycline, 
taxane, or both). In this trial, eight q3 weekly cycles of adjuvant capecitabine therapy was shown 
to be safe and effective in prolonging disease-free survival and overall survival among patients 
with HER2-negative breast cancer who had residual invasive disease.(4) Given these data, as 
well as promising data supporting the use of immune checkpoint inhibition (ICI) in TNBC, there 
is a strong interest in testing the combination of an ICI in combination with capecitabine. In fact, 
a phase Ib study of metastatic breast cancer, pembrolizumab plus capecitabine (2000mg bid, 7 
days on and 7 days off) showed encouraging safety and efficacy. Overall response for the 
capecitabine+ pembrolizumab arm was 43% (5 PR, 1 CR, 2 SD) with median progression free 
survival of 155 days.(5)  
 
Combination of AKT inhibitor with ICI: PTEN is a well-known negative regulator of AKT. 
PTEN loss is associated with decreased T cell infiltration and reduced efficacy of ICI. PI3K-beta 
inhibitor improves the efficacy of both anti-PD-1 and anti-CTLA-4, supporting the rationale of 

Page 26 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
26 
exploring combinations of ICI and PI3K/AKT pathway inhibitors(17). In a phase IB study, the 
combination of ipatasertib, atezolizumab and paclitaxel or nab-paclitaxel showed a promising 
response rate of 73% in a cohort of 26 patients with unresectable, locally advanced/metastatic 
TNBCs previously untreated in the metastatic setting.  Interestingly, responses were high 
irrespective of PD-L1 status or PI3K/AKT/PTEN alteration status(2). 
 
In the third arm of this study, arm C, we aim to test the combination of ipatasertib, capecitabine 
and atezolizumab in patients with PD-L1 mTNBC. The primary end point will be safety and 
tolerability of the regimen. Identifying the safe dose of these three drugs in combination will 
pave the way to evaluate this triplet combination in early stage disease. A secondary endpoint 
will be the response rate and evaluation of the role of PD-L1 status.

STUDY DESIGN 
3.1 
DESCRIPTION OF THE STUDY 
This is a Phase I trial of ipatasertib plus either carboplatin or carboplatin/ paclitaxel in 
patients with metastatic TNBC. The combination of paclitaxel and ipatasertib have been 
well-tolerated and the recommended phase II dose is ipatasertib 400mg po daily 3 weeks 
on/1 week off, paclitaxel 80mg/m2 days 1, 8,15 of every 4 week cycle based on the 
previous data of LOTUS trial. In the current trial, two dosing regimen will be tested in this 
study. In triplet schedule A, carboplatin AUC 2, paclitaxel 80mg/m2 will be added on day 
1, 8 and 15 of every 4 weeks cycle while patients receive ipatasertib of 400mg daily. In 
doublet schedule B, carboplatin AUC 2 on days 1, 8, 15 every 28 days will be added to 
ipatasertib 400mg daily continuous dosing. 
 
We will use the Phase I Queue (IQ) 3+3 design that insures patient risk does not exceed 
the maximum risk permitted in the traditional 3+3 design, while enabling fewer study 
holds and permits the PI to proceed with a more rapid completion of the Phase I study. A 
variety of 3-at-risk designs have been conducted, including NCI/CTEP studies based on 
the 3+3 risk constraints (NCT02568553, NCT01567709). This method has been shown 
(presented at JSM 2016, with the latest design presented at JSM 2018, Frankel, P, 
Activity #359, manuscript submitted) to reduce study duration by an average of 
approximately 23% for a typical Phase I study, with a median increase in the number of 
patients of 1-4, while reducing the number of patients turned away due to lack of slots. 
The operating characteristics demonstrate negligible difference in the dose chosen for the 
MTD, and in the number of DLTs reported in patients treated above the MTD (see 
statistical considerations). The details of the design are described below (D: Comparison 
of the 3+3 and the Phase I Queue 3+3 (IQ 3+3) Design Decisions).  
 
For response and PFS estimates, and to confirm the recommended Phase II dose 
obtained from the dose escalation, we will enroll an additional cohort of patients until the 
number treated and evaluable for DLT considerations at the recommended phase II dose 
is 14 patients for the doublet (Table B) and for the triplet schedules (Table A). 
  
All eligible patients who start treatment at the recommended dose will be considered in 
the calculation of the response rate. 
 
Sample size for the doublet and triplet schedules A and B: Expected sample size (if level 
1 is well-tolerated) is 14 patients for both the doublet and triplet, for an expected total 
sample-size of 28 patients. Additional cohorts of 6-8 patients are required if level 1 is not 
well-tolerated for each schedule.

Protocol 18496, Version 2.7

Sample-size for the triplet Arm C: The starting dose level for schedule C is not the 
highest possible dose to be tested, which differs from Arm A and B.  Once the MTD and 
recommended phase 2 dose (RP2D) is selected for Arm C, at least 12 total patients will 
be treated at the RP2D.  The expected number of patients (based on 800 simulations 
with DLT rates of 9.0%, 10.8%, 13.6% and 18.0% or with DLT rates of 6.7%, 7.6%, 9.0% 
and 10.8% for levels 1-4) is between 17 and 18 patients for dose-finding, and the 
interquartile range is 15-20 patients.  If after 12 patients have been accrued to the RP2D 
in total, the number of total patients remains less than 21, additional patients can be 
accrued to the RP2D (e.g. if the RP2D is dose level 1, with 6 patients treated, and 2 
DLTs on dose level 2 for a total 8 patients, 13 additional patients can be added to dose 
level 1 as opposed to only 6).

up, patient has withdrawn consent, or patient has completed at least 24 months of follow-up 
after start of treatment. The end of the study is expected to occur 18 months after the last 
patient is enrolled. In addition, the Investigator may decide to terminate the study at any time. 
The total length of the study, from screening of the first patient to the end of the study, is 
expected to be approximately 36 months. 
3.3 
RATIONALE FOR STUDY DESIGN 
3.3.1 
Rationale for Ipatasertib  
 In previous studies, the ipatasertib starting dose of 400 mg QD on Days 1−21 of each 28-day 
cycle was selected on the basis of safety and pharmacokinetics data from Arm C of 
Study PAM4983g (Phase Ib trial of ipatasertib combined with paclitaxel; refer to the Ipatasertib 
Investigator's Brochure for details). The pharmacokinetics of paclitaxel and ipatasertib following 
co-administration showed no evidence of drug−drug interaction and 400 mg ipatasertib was 
better tolerated than 600 mg ipatasertib in this combination.  
In the randomized, placebo-controlled Phase II study (GO29227) in patients with locally 
advanced or metastatic TNBC, the combination of ipatasertib 400 mg administered QD on Days 
1−21 of each 28-day cycle and paclitaxel 80 mg/m2 administered weekly on Days 1, 8, and 15 of 
each 28-day cycle was generally well tolerated and showed an improvement in PFS. The 
sparse sampling exposure results in this study were also consistent with the known PK profiles 
of ipatasertib (and its metabolite G-037720).  
In addition, the totality of pharmacodynamics data from Phase I (PAM4743g, 
PK/pharmacodynamic analysis) and safety and efficacy data (including exploratory exposure-
response analyses, data on file) from randomized Phase II studies of ipatasertib (Study 
GO29227 and Study GO27983, which evaluated two dose levels of 200 mg and 400 mg of 
ipatasertib in patients with metastatic castration-resistant prostate cancer) support the selected 
starting dose of 400 mg ipatasertib for sufficient pathway inhibition and efficacy with a generally 
acceptable safety profile (refer to the Ipatasertib Investigator's Brochure for details). In the 
ipatasertib + paclitaxel arm of the GO29227 study, despite dose reduction of ipatasertib that 
occurred in 21.3% of patients due to adverse events, discontinuation of ipatasertib due to any 
adverse event was 6.1%, and the median cumulative dose intensity of both ipatasertib and 
paclitaxel were maintained at 99.0% (ipatasertib) and 100% (paclitaxel).  
The ipatasertib starting dose of 400 mg daily was selected based on safety data from the Phase 
Ib portion of the study GO27983. Ipatasertib at the 400-mg dose level has generally been well 
tolerated in combination with abiraterone and prednisone. The most common AEs reported 
were Grade 1 and Grade 2 gastrointestinal symptoms, including nausea, vomiting, and diarrhea. 
These may be managed effectively with standard supportive care. Overall, the spectrum and 
frequency of AEs attributable to ipatasertib in combination with abiraterone is similar to that of 
single-agent ipatasertib in the PAM4743g trial.

Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
33 
The patients treated at the 400 mg dose of ipatasertib achieved a similar plasma exposure at 
steady-state relative to patients treated at 400−600 mg on a 21-of-28 day schedule (the single-
agent MTD). At 400 mg daily, the cumulative ipatasertib dose administered over 28 days is 
similar to that at 600 mg dosed on a 21-of-28 day schedule. Significant pathway inhibition was 
demonstrated at the 400 mg dose level (for further details, see the Ipatasertib Investigator’s 
Brochure).  
In the current study, ipatasertib continuous dosing for arms A and B was planned in order to 
better understand the tolerability of the daily dosing in combination with chemotherapy. 
Hypothetically continuous AKT inhibiting may provide sustained target suppression and possible 
improved disease control. Therefore the dosing schedules of this clinical trial were selected 
based on continuous dosing of ipatasertib. For Arm C, to be consistent with LOTUS  and 
ongoing phase III trials, ipatasertib 3 weeks on, 1 week off schedule was chosen. Due to 
concerns of increased risk of diarrhea, ipatasertib starting dose of 300mg was chosen.  
 
3.3.2 
Rationale for Carboplatin/Paclitaxel or Carboplatin  
Carboplatin combination therapy has been shown to be effective in treatment of metastatic 
breast cancers (Perez et al. 2004). Weekly paclitaxel (100mg/m2) was combined with weekly 
carboplatin AUC 2, days 1, 8, and 15 on a 4 week schedule in a cohort of advanced breast 
cancer patient. The regimen was effective with a response rate of 62% and well tolerated with a 
grade 3/4 neutropenia rate of 35%. Other grade 3/4 toxicities included neuropathy (11%), 
infection (6%), weakness (6%), anemia (5%), and paresthesia (3%) (Loesch et al. 2002). In the 
LOTUS trial, grade 3/4 neutropenia rate was 10%. There is a strong rationale to test continuous 
dosing of ipatasertib for consistent AKT inhibition. Therefore in the current study, we proposed 
two dosing schedules to study the combination of carboplatin alone with ipatasertib or 
carboplatin/paclitaxel in combination with continuous dosing of ipatasertib. Starting doses for 
each combination and the dosing schedules are described in detail in section 3.1. 
Single agent activity of carboplatin in breast cancer has been extensively studied. In several 
phase II studies of patients with metastatic breast cancer, single-agent carboplatin produced 
objective response rates of 20%–35% in previously untreated patients (Kolaric et al. 1991, 
Martin et al. 1992, O’brien et al. 1993) at dosing of 400 mg/m2 every 3 or 4 weeks, or based on 
glomerular filtration rate to achieve an area under the concentration-versus-time curve (AUC) of 
7 mg/ml minute every 4 weeks. In contrast, objective responses were 8-16% with these 
carboplatin schedules in patients treated previously with chemotherapy for metastatic disease 
(O’brien et al. 1993, Carmo-Pereira et al. 1990).  
3.3.3 
Rationale for Capecitabine and Atezolizumab 
In CREATE-X trial, adjuvant capecitabine treatment was shown to be safe and effective in 
prolonging disease-free survival and overall survival among patients with HER2-negative breast 
cancer who had residual invasive disease. A phase Ib study of pembrolizumab plus 
capecitabine (2000mg bid, 7 days on and 7 days off) showed encouraging safety and efficacy. 

Page 34 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
34 
Overall response for the capecitabine+ pembrolizumab arm was 43% (5 PR, 1 CR, 2 SD) with 
median progression free survival of 155 days.3  Since both capecitabine and ipatasertib are 
associated with diarrhea, a lower dose of capecitabine starting dose at 750mg/m2 will be used. 
Capecitbine 7 days on and 7 day off schedule is based on the following publication: Traina TA, 
Dugan U, Higgins B, Kolinsky K, Theodoulou M, Hudis CA, Norton L. Optimizing chemotherapy 
dose and schedule by Norton-Simon mathematical modeling Breast disease. 2010 Jan 
1;31(1):7-18. Detailed dosing schedules are described in detail in section 3.1. Atezolizumab 
dose was selected based on Impassion 130 trial and FDA package insert. 
 
3.3.4 
Rationale for Patient Population 
Despite multiple treatment options, advanced breast cancer remains an incurable disease. 
Although chemotherapy is a mainstay treatment for TNBC, resistance inevitably develops and 
benefit is often short-lived. Ipatasertib with paclitaxel has shown encouraging clinical benefit for 
TNBC from the randomized Phase II study (GO29227 or LOTUS). In Study GO29227, patients 
with TNBC in the ipatasertib + paclitaxel arm showed a more pronounced improvement in PFS 
in the pre-specified patient population with PIK3CA/AKT1/PTEN-altered tumors (hazard 
ratio = 0.44, 9.0 months vs. 4.9 months) compared with PIK3CA/AKT1/PTEN non-altered 
tumors (hazard ratio = 0.76, 5.3 months vs. 3.7 months) or unselected ITT patients (hazard 
ratio = 0.60, 6.2 months vs. 4.9 months).  
For patients with metastatic HR+/HER2− breast cancer, approved therapy during the endocrine-
sensitive phase includes CDK4/6 inhibitors and PI3K/Akt pathway inhibitors such as everolimus. 
Preliminary data from the Phase Ib study PAM4983g suggest that HR+/HER2− patients may still 
respond to the combination of ipatasertib + paclitaxel after prior exposure to PI3K/Akt pathway 
inhibitors (e.g., PI3K inhibitors) (Isakoff et al. 2014). The efficacy of ipatasertib for patients 
previously treated with CDK4/6 inhibitors is unknown, but these patients are not excluded from 
participation in this study. 
3.3.5 
Rationale for Biomarker Assessments  
Genomics: Genomic analysis is increasingly informing our understanding of disease 
pathobiology. Next-generation sequencing (NGS) such as whole exome sequencing (WES) 
provides a comprehensive characterization of the exome, and along with clinical data collected 
in this study, may provide the opportunity to develop new therapeutic approaches. Triple 
negative breast cancer is a heterogeneous disease with many distinct subtypes as defined by 
molecular signatures and a diverse array of mutational profiles.  
In addition to PIK3CA/AKT1/PTEN−alteration status, samples will be assessed for additional 
biomarkers in an effort to identify factors that may correlate with the safety and efficacy of 
treatment with ipatasertib combined with carboplatin or carboplatin/paclitaxel. 
In addition, all submitted tumor or blood samples at screening and end-of-study may be 
evaluated using additional genomic testing such as NanoString nCounter Breast Cancer 360 
panel and data analysis to provide a more comprehensive understanding of resistance 

Page 35 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
35 
mechanisms to carboplatin/AKT inhibitor, which may lead to future development of alternative 
treatment strategies.  
Carboplatin has shown significant efficacy in BRCA1/2 mutated tumors. The BRCA status will 
also be examined using NGS, WES, and/or other methods. The collected DNA from blood 
samples and tumor tissue from this study will be analyzed to identify germline (e.g., BRCA1/2) 
and somatic alterations that are predictive of response to study drug, are associated with 
progression to a more severe disease state, are associated with acquired resistance to study 
drug, or can increase the knowledge and understanding of disease biology.  
Gut Microbiome: Recently, it has become evident that the gut microbiota modulates the 
response to cancer therapy and susceptibility to toxic side effects (Roy et al. 2017). The best 
characterized therapies are oxaliplatin (Tesniere et al. 2010) and cyclophosphamide (Daillère 
et al. 2016). The gut microbiota primes myeloid cells for production of reactive oxygen 
species in the case of oxaliplatin, and facilitates the induction of an anticancer T cell 
response in the case of cyclophosphamide (Daillère et al. 2016). The role of gut microbiota in 
modulating the response to tyrosine kinase inhibitors remains to be discovered. Evidence of 
the important role of the microbiota in controlling cancer therapy effectiveness and toxicity is 
derived mainly from data in experimental animals, and translation of these findings to human 
clinical medicine remains challenging. Additional clinical data need be obtained in order to 
understand how ipatasertib affects the gut microbiota, and to develop strategies to attenuate 
the gastrointestinal side effects of ipatasertib. Therefore, gut microbiota analysis will be 
included in this study to assess the correlation of treatment side effects such as diarrhea and 
treatment response. Stool sample will be collected at baseline, C4D1 and end-of-study visit 
(Appendix 1 Study Calendar). 
Plasma Calprotectin: Calprotectin, first described in 1980 by Fagerhol, is released by activated 
neutrophils, and accounts for more than 40% of the cytosolic proteins of neutrophils. Elevated 
concentrations of calprotectin can be measured in plasma, cerebrospinal fluid, synovial fluid, 
urine, and feces when ongoing inflammation is present, or in malignant conditions (Fagerhol et 
al. 1980). Increased fecal calprotectin (FCP) concentrations have been found in gastric and 
colorectal cancers as well as in inflammatory bowel disease (IBD). The high fecal calprotectin 
concentrations detected in IBD can be explained by increased turnover of leukocytes in the gut 
wall, and increased migration of neutrophils into the gut lumen. FCP was found to be strongly 
associated with colorectal inflammation indicating organic disease, and is a simple and non-
invasive method for assessing excretion of macrophages into the gut lumen. FCP values can be 
used to screen asymptomatic patients, evaluate the response to treatment, and predict disease 
relapse in patients with IBD (Erbayrak et al. 2009). It is unclear if FCP is associated with 
targeted therapy-induced bowel inflammation and/or diarrhea. In this study, FCP analysis will be 
used for detection of bowel inflammation, by collecting plasma samples at baseline, C2D1 and 
end-of-study visit (Appendix 1 Study Calendar). 
For gut microbiome collection kit information and instructions, refer to Appendix 7. For 
biospecimen sample transportation, refer to Appendix 10.

3.3.6 
Rationale for Patient-Reported Outcome 
Assessments  
Patient reported outcomes (PROs) provide an understanding of the impact a treatment has on a 
patient. The QLQ-C30 is a validated instrument that has been widely used in assessing quality 
of life in patients with cancer. The core instrument assesses global health status/quality of life, 
functions (physical, role, emotional, cognitive, and social), and general cancer symptoms. For 
EORTC QLQ-C30 forms, refer to Appendix 11.

• 
For women of childbearing potential: agreement to remain abstinent (refrain from 
heterosexual intercourse) or use contraceptive methods with a failure rate of < 1% per year 
during the treatment period and for 6 months after the last dose of study treatment. Women 
must refrain from donating eggs during this same period. 
A woman is considered to be of childbearing potential if she is post-menarcheal, has not 
reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified

ovaries and/or uterus). 
Examples of contraceptive methods with a failure rate of < 1% per year include bilateral 
tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-
releasing intrauterine devices, and copper intrauterine devices. 
The reliability of sexual abstinence should be evaluated in relation to the duration of the 
clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., 
calendar, ovulation, symptothermal, or post ovulation methods) and withdrawal are not 
acceptable methods of contraception.

antimicrobial preservatives. The prepared solution for infusion should be used immediately to 
limit microbial growth in case of potential accidental contamination. If not used immediately, in-
use storage time and conditions prior to use are the responsibility of the user. For flat or fixed 
dosing, (e.g., 800 mg, 840 mg, or 1200 mg) in 250 mL IV infusion bags, the dose solution may 
be stored at 2°C-8°C (36°F-46°F) for 24 hours or at ambient temperature ≤ 25C° (77°F) for 8 
hours. This time includes storage and time for administration for infusion. 
 
4.3.2 
Study Treatment Dosage, Administration, and 
Compliance 
The treatment regimens are summarized in Section 3.1.  
Any overdose or incorrect administration of any of the study treatments should be noted in the 
patient’s medical records. Adverse events associated with an overdose or incorrect 
administration of any of the study treatments should be recorded in the patient’s medical 
records.  
Guidelines for dosage modification and treatment interruption or discontinuation for patients who 
experience adverse events are provided in Section 6.2.  
4.3.2.1 
Ipatasertib 
Ipatasertib will be administered at the starting dose of 400mg or 300mg (depending on dosing 
level assignment) orally QD on a continuous dosing for Arms A & B, 1-28 days cycle. For Arm 
C, ipatasertib starting dose will be 300mg daily, days 1-21 of 28 day cycles. Treatment will 
continue until the patient experiences disease progression, intolerable toxicity, or withdraws 
consent (see Section 3.1 for details).  
 
Each dose of ipatasertib should be taken with a minimum of 3 ounces (90 mL) of fluid. 
Ipatasertib may be taken with or without food. If a dose is missed (not taken within 8 hours after 
the scheduled dosing time), the patient should resume dosing with the next scheduled dose. 
Missed or vomited doses will not be made up. 
A sufficient amount of ipatasertib should be provided to the patient to last one 
treatment cycle. Patients will be instructed to bring their bottles of ipatasertib 
and their medication diaries to each study visit.

44 
Study participants are required to document ipatasertib and loperamide or other anti- diarrhea 
medication usage with a pill diary (Appendix 9).  
4.3.2.2 
Carboplatin 
Carboplatin will be given at a starting dose of AUC at 2 on days 1, 8, and 15 every 28 days for 
Arm A. Carboplatin will be given at a starting dose of AUC at 2 on days 1,8,15 of 28 day cycles 
for Arm B. Carboplatin will be administered as an intravenous infusion over 30 minutes, 
administered after paclitaxel dose.  
 
Carboplatin dose (mg) = AUC X (GFR + 25)  
(Calculated total dose is in mg -not mg/m2)  
 
The Creatinine Clearance (to replace GFR) will be calculated for each treatment course using the 
Cockcroft-Gault formula (Appendix 2):  
 
Note: The serum creatinine level to be used in the following calculations must be ≥ 0.7 mg/dL 
for patient age <65, if the measured serum creatinine level is < 0.7 mg/dL, use 0.7 mg/dL as the 
value in this calculation. For patient age ≥ 65, if measured serum creatinine is < 0.8 mg/dL, use 
0.8 mg/dL as the value in this calculation.  
 
For Females:  
 
CrCI = (140-age) X wt. in kg. X 0.85  
        
 
72 X serum creatinine* 
 
Use calculated creatinine clearance for GFR in Cockcroft-Gault formula.  
 
For Males:  
 
CrCI = (140-age) X wt. in kg. 
        
72 X serum creatinine* 
 
Use calculated creatinine clearance for GFR in Cockcroft-Gault formula.  
 
Note: Remember to re-calculate the dose for each treatment cycle. The actual body weight should 
be used for all calculations. If the actual weight is greater than 1.2 times the ideal body weight, 
use 1.2 times the ideal body weight as the value in this calculation. Serum creatinine will be check 
on each day of carboplatin dose. Readjust carbo dose if dose changes on days 8 and 15 is greater 
than 10% per institutional guidelines. 
 
Note: The GFR (calculated by Cockcroft-Gault) used in the Calvert formula to calculate AUC-
based dosing should not exceed 125 mL/min under any circumstance. By definition, this results 
in the following upper limits on the dose to be administered, by AUC target:

4.3.2.3 
Paclitaxel  
Paclitaxel will be given at a dose of 80 mg/m2 administered by IV infusion on days 1, 8, and 15 
of every 28 day cycles for ArmA. 
The paclitaxel infusion will be delivered over at least 60 minutes for each dose per institutional 
guidelines and administered after the oral dose of ipatasertib and before carboplatin dose. 
Patients should be monitored during paclitaxel administration per institutional policies. 
Calculation of body surface area for the purposes of dosing of paclitaxel should be made 
according to the prescribing information. If the patient's weight changes by >10% during the 
study, the body surface area and drug doses should be recalculated. 
Patients may receive anti-emetic and other prophylactic treatments, according to 
institutional practice. 
Refer to FDA package insert for detailed instructions on drug preparation, storage, and 
administration. 
If patients develop moderate or severe allergy to paclitaxel despite adequate 
premedication, weekly nab-paclitaxel can be used to replace weekly paclitaxel following 
standard institutional practice after discussion with PI. 
4.3.2.4 
Capecitabine 
Capecitabine will be given at a starting dose of 750mg/m2 1 week on, 1 week off every 2 weeks 
(28 days cycle) for Arm C. Calculation of body surface area for the purposes of dosing of 
capecitabine should be made according to the prescribing information. If the patient's weight 
changes by >10% during the study, the body surface area and drug doses should be 
recalculated.Patients may receive anti-emetic and other prophylactic treatments, according to 
institutional practice. 
Refer to FDA package insert for detailed instructions on drug preparation, storage, and 
administration. 
4.3.2.5 
Atezolizumab

4.3.2.6 
Criteria for Starting Subsequent Cycles 
All toxicities (except alopecia, fatigue and lymphopenia, cancer-related pain, hypertension, 
hyperglycemia, hypoalbuminemia, elevated serum alkaline phosphatase, neuropathy) must 
resolved to ≤ grade 2neutropenia and thrombocytopenia prior to initiation of the next cycle 
of therapy. Qualifying laboratory tests and procedures can be obtained up to 72 hours before 
planned initiation of therapy from the 2nd cycle onwards. 
 
4.3.2.7 
Dose Interruption, Dose Delays and Dose Modification 
For criteria of dose interruption, dose delay and dose modification, please refer to Section 
5.1.5: Management of Patients Who Experience Adverse Events. 
For all  arms, if ipatasertib dose is held due to toxicity, make-up dose will not be given. 
For both Arm A and Arm B, if the infusion dose on Day 1, 8, or 15 is missed due to toxicity, 
make-up dose will not be given.  
If patient encounters dose delays, timing of restaging scans will be determined by 
treatment cycles, not by total weeks on study. 
4.3.2.8 
Assessments and Special Monitoring 
For a detailed list of all study procedures including timing and windows, see section 4.5  and 
Appendix_1. 
Management of atezolizumab specific adverse events: Toxicities associated or possibly 
associated with atezolizumab treatment should be managed according to standard medical 
practice. Investigators are encouraged to review and refer to Clinical Practice Guidelines for 
management of immune-related adverse events in patients treated with immune checkpoint 
inhibitors published by the American Society for Clinical Oncology (Brahmer 2018) and the 
European Society for Medical Oncology (Haanen 2017), along with the dose modification 
guidelines provided in this protocol for evaluation and management of potential immune adverse 
events. Additional tests, such as autoimmune serology or biopsies, should be used to evaluate 
for a possible immunogenic etiology. 
Although most immune-related adverse events observed with immunomodulatory agents have 
been mild and self-limiting, such events should be recognized early and treated promptly to 
avoid potential major complications. More severe immune-related toxicities may require acute 
management with topical corticosteroids, systemic corticosteroids, or other immunosuppressive 
agents. Management of patients with Grade 3 or 4 atezolizumab related immune toxicities will 
require aggressive immunosuppressive therapies. For details, refer to section 5.1.5.7.11. 
4.3.3 
Other Treatments: Premedications and Prophylactic 
Treatment 
Because of the known potential for allergic reactions to paclitaxel and/or the 

Page 47 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
47 
Cremophor® vehicle or carboplatin, precautions must be taken to decrease the risk of 
anaphylaxis. Patients must be premedicated prior to paclitaxel with dexamethasone, 
diphenhydramine, and an H2-receptor blocker (i.e., ranitidine or famotidine) or per institutional 
practice. H2-receptor antagonists, such as cimetidine, which are known to inhibit cytochrome 
P450, are excluded. 
 
Steroid use may potentiate hyperglycemia, which can also be induced by ipatasertib.  
For ≥ Grade  2 hyperglycemia (fasting glucose 160-250), STAT endocrinology consult 
should be arranged by treating physician in 24h. 
 
Diarrhea is a common adverse event associated with ipatasertib and/or paclitaxel treatment. In 
this current study, to improve diarrhea management and patient experiences, loperamide (2 mg 
twice a day or 4 mg once a day) will be administered daily as prophylaxis for diarrhea in the first 
cycle if allowed by local guidance. If side effects of loperamide are not tolerated, doses may be 
reduced at any time. Investigators are encouraged to continue this dosing for the remainder of 
the study using their discretion based on clinical judgments. If loperamide is ineffective in 
controlling diarrhea, other agents such as lomotil (diphenoxylate/atropine) and or 
colestipol can be used per discretion of treating physician.  
Study participants are required to document their diet, bowel movement and anti-diarrheal 
medication usage (Appendix 8).  
If diarrhea occurs, it should be managed per guidelines in Table 5, page 65; upon resolution or 
when study treatment is restarted, loperamide prophylaxis should be considered to resume and 
continue based on clinical judgments.  
4.3.4 
Investigational Medicinal Product (IMP) Accountability

4.4 
CONCOMITANT THERAPY, PROHIBITED FOOD, AND ADDITIONAL 
RESTRICTIONS 
Concomitant therapy consists of any medication (e.g., prescription drugs, over-the-counter 
drugs, vaccines, herbal or homeopathic remedies, nutritional supplements) used by a patient in 
addition to protocol-mandated treatment from 14 days prior to initiation of study treatment to the 
treatment discontinuation visit. All such medications should be reported to the investigator and 
recorded in the patient’s medical records.  
4.4.1 
Permitted Therapy and Supportive Care 
Patients are permitted to use the following therapies during the study: 
• 
Oral contraceptives, as allowed per local guidelines 
• 
Palliative radiotherapy (e.g., treatment of known bony metastases or symptomatic relief of 
pain) as outlined below: 
Palliative radiotherapy is permitted for a preexisting lesion, provided it does not 
interfere with the assessment of tumor target lesions (e.g., the lesion to be irradiated 
must not be a site of measurable disease). Study treatment should be suspended 
during palliative radiotherapy (see Section 4.4.3) 

Page 49 of 172

Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
49 
• 
Premedication with antihistamines, antipyretics, and/or analgesics for each paclitaxel 
administration 
• 
Prophylactic use of loperamide is mandated in the first cycle, and as clinically 
indicated in subsequent cycles to prevent diarrhea. Patients who experience diarrhea 
should be on treatment doses of loperamide per the management guidelines provided in 
Section 5.1.5.7; please refer to that section for additional details. Patients should be 
educated/reminded to be cognizant of the onset, duration, severity, and frequency of 
symptoms and the medications administered.  
• 
Granulocyte colony-stimulating factor treatment is permitted for patients receiving paclitaxel 
or carboplatin/paclitaxel arm. The primary prophylaxis should be administered per the 
ASCO, EORTC, and European Society for Medical Oncology (ESMO) guidelines; namely, 
in patients who are ≥ 60 years of age and/or with comorbidities (Smith et al. 2006; Aapro et 
al. 2011). 
• 
Bisphosphonate therapy or RANKL inhibitor therapy (e.g., zolendronic acid and 
denosumab) used specifically to prevent skeletal events (e.g., bone metastasis, 
osteoporosis) is allowed.  
• 
Luteinizing hormone-releasing hormone (LHRH) agonists for ovarian function preservation 
are allowed.  
• 
Patients who have type I or type II diabetes mellitus must be followed by an endocrinologist 
when on study. 
 
In general, investigators/treating physicians should manage a patient’s care with supportive 
therapies as clinically indicated and per institutional practice. For example, patients who 
experience infusion-associated symptoms may be treated symptomatically with acetaminophen, 
ibuprofen, diphenhydramine, and/or H2-receptor antagonists (e.g., famotidine, cimetidine), or 
equivalent medications per institutional practice. Serious infusion-associated events manifested 
by dyspnea, hypotension, wheezing, bronchospasm, tachycardia, reduced oxygen saturation, or 
respiratory distress should be managed with supportive therapies as clinically indicated 
(e.g., supplemental oxygen and β2-adrenergic agonists).  
Systemic corticosteroids are recommended, at the discretion of the investigator, for the 
treatment of specific immune-related adverse events when associated with atezolizumab (refer 
to the Atezolizumab Investigator's Brochure for details). Atezolizumab should be temporarily 
held during systemic corticosteroids treatment. 
For usage of antiemetics and treatment for neuropathy, physicians are advised to follow ASCO 
and/or NCCN guidelines, as appropriate. 
4.4.2 
Cautionary Therapy for Ipatasertib 
Patients who require radiation or surgery as part of medical treatment in the absence of 
radiographic disease progression must exercise caution, and all study treatment should be 

Page 50 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
50 
temporarily held for at least 7 days before and after the procedure (at least 14 days after 
radiation is recommended). After the temporary treatment hold is complete, study treatment  
In vitro data suggest that ipatasertib is metabolized by CYP3A and may be a time-dependent 
inhibitor of CYP3A4. A clinical drug−drug interaction study with midazolam (a sensitive CYP3A 
substrate) showed a 2.2-fold increase in midazolam exposures in presence of steady-state 
Ipatasertib dosed at 600 mg QD. Therefore, sensitive CYP3A substrates with narrow 
therapeutic window should be avoided. Given that ipatasertib is primarily metabolized by 
CYP3A, there is a high potential for drug−drug interactions of ipatasertib with any medication 
that strongly inhibits or induces CYP3A. Data from a clinical study showed that ipatasertib 
exposures were reduced by approximately 50% when co-administered with enzalutamide, a 
strong CYP3A inducer. Strong CYP3A inhibitors are expected to increase ipatasertib exposures 
significantly.  
Therefore, the following drugs should be avoided or used with caution.  
• 
Strong CYP3A4/5 inhibitors, such as, but not limited to, atazanavir, clarithromycin, indinavir, 
itraconazole, ketoconazole, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, 
troleandomycin, voriconazole, and/or grapefruit juice  
• 
Strong CYP3A4/5 inducers, such as, but not limited to, rifampin, carbamazepine, 
rifapentine, phenytoin, phenobarbital, and/or St. John’s wort or hyperforin 
• 
CYP3A4/5 substrates with a narrow therapeutic index, such as, but not limited to, alfentanil, 
astemizole, terfenadine, cisapride, cyclosporine, fentanyl, pimozide, quinidine, sirolimus, 
tacrolimus, ergot alkaloids ergotamine, and/or dihydroergotamine 
• 
Paclitaxel exposures may be increased due to CYP2C8 inhibition; therefore, strong 
and moderate CYP2C8 inhibitors, such as gemfibrozil, teriflunomide, clopidogrel, 
and deferasirox should be used with caution during treatment with paclitaxel. 
Similarly, CYP2C8 inducers should be avoided or used with caution.  
• 
Patients who require short-term use of a strong CYP3A4/5 inhibitor or inducer or use of 
sensitive CYP3A substrates with a narrow therapeutic window for medical treatment 
(i.e., an alternative treatment cannot be used) must exercise caution and all study treatment 
should be temporarily held until at least 5 half-lives or 7 days after the last dose of these 
drugs.  
• 
Patients are permitted to take moderate inhibitors of CYP3A4 with caution. 
 
Patients should be closely monitored. Refer to the following information for further guidance on 
CYP450−drug interactions and a list of common substrates, inhibitors, and inducers:

Herbal Therapies: 
Concomitant use of herbal therapies is prohibited because their pharmacokinetics,

safety profiles, and potential drug-drug interactions are generally unknown. 
 
4.4.3 
Cautionary Therapy for Capecitabine (Arm C) 
Anticoagulants: Anticoagulants Altered coagulation parameters and/or bleeding have been 
reported in patients taking capecitabine concomitantly with coumarin-derivative anticoagulants 
such as warfarin and phenprocoumon. These events occurred within several days and up to 
several months after initiating capecitabine therapy and, in a few cases, within 1 month after 
stopping capecitabine. These events occurred in patients with and without liver metastases. In a 
drug interaction study with single-dose warfarin administration, there was a significant increase 
in the mean AUC of S-warfarin. The maximum observed INR value increased by 91%. This 
interaction is probably due to an inhibition of cytochrome P450 2C9 by capecitabine and/or its 
metabolites.  
Phenytoin: The level of phenytoin should be carefully monitored in patients taking capecitabine 
and phenytoin dose may need to be reduced. Some patients receiving capecitabine and 
phenytoin had toxicity associated with elevated phenytoin levels. Formal drug-drug interaction 
studies with phenytoin have not been conducted, but the mechanism of interaction is presumed 
to be inhibition of the CYP2C9 isoenzyme by capecitabine and/or its metabolites.  
CYP2C9 substrates Other than warfarin, no formal drug-drug interaction studies between 
capecitabine and other CYP2C9 substrates have been conducted. Care should be exercised 
when capecitabine is coadministered with CYP2C9 substrates.  
Drug-Food Interaction: Food was shown to reduce both the rate and extent of absorption of 
capecitabine. In all clinical trials, patients were instructed to administer capecitabine within 30 
minutes after a meal. It is recommended that capecitabine be administered with food. 
 
4.4.4 
Prohibited Therapy  
Use of the following concomitant therapies is prohibited as described below for ipatasertib. 
• 
Investigational therapy (other than protocol-mandated study treatment) is prohibited within 
14 days prior to initiation of study treatment and during study treatment. 
• 
Concomitant therapy intended for the treatment of cancer (including, but not limited to, 
chemotherapy, hormonal therapy, immunotherapy, radiotherapy, and herbal therapy) is 
prohibited for various time periods prior to starting study treatment, depending on the agent 
( see Section 4.1.2), and during study treatment, until disease progression is documented 
and the patient has discontinued study treatment, with the exception of palliative 
radiotherapy and local therapy under certain circumstances (see Section 4.4.1 for details 
for details). 
• 
Chronic use of a strong CYP3A4/5 inhibitor or inducer, or sensitive CYP3A substrates with 
a narrow therapeutic window that are deemed not permissible after enrollment (refer to the 
guidance in Section 4.4.2.1) 
• 
Live, attenuated vaccines (e.g., FluMist®) are prohibited within 28 days prior to start of 
treatment, during study treatment, and for 5 months after the last dose of study treatment  

Page 52 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
52 
• 
Systemic immunostimulatory agents (including, but not limited to, interferons and IL-2) are 
prohibited within 28 days or 5 half-lives of the drug, whichever is longer, prior to start of 
treatment and during study treatment because these agents could potentially increase the 
risk for autoimmune conditions when given in combination with atezolizumab.  
• 
Systemic immunosuppressive medications (including, but not limited to, azathioprine, 
methotrexate, and thalidomide) are prohibited during study treatment because these agents 
could potentially alter the efficacy and safety of atezolizumab.  
• 
Steroids greater than or equivalent of 10 mg prednisone/day is contraindicated. 
4.4.5 
Prohibited Food 
 
Use of the following foods is prohibited as described below: 
• 
Consumption of grapefruit juice, a potent CYP3A4 enzyme inhibitor, is prohibited during the 
study treatment period and for 10 days after the last dose of study treatment. 
• 
Consumption of St. John’s wort, a potent CYP3A4 enzyme inducer, is prohibited for up to 
14 days prior to and during the study treatment period, and for 10 days after the last dose of 
study treatment. 
 
4.4.6 
Additional Restrictions 
No food or fluids other than water will be allowed for 8 hours prior to each Day 1 study visit until 
after study laboratory samples for fasting glucose and fasting lipid profile, as applicable, are 
obtained (see Appendix 1 Study Calendar). 
4.5 
STUDY ASSESSMENTS  
The schedule of activities to be performed during the study is provided in Study calendar. All 
activities must be performed and documented for each patient.  
Patients will be closely monitored for safety and tolerability throughout the study. Patients 
should be assessed for toxicity prior to each dose; dosing will occur only if the clinical 
assessment and local laboratory test values are acceptable. 
4.5.1 
Informed Consent Forms and Screening Log 
 
Voluntary, written, dated, and signed informed consent for participation in the study must 
be obtained before performing any study-related procedures (including screening 
evaluations or submission of archival tissues). Informed Consent Forms for enrolled patients 
and for patients who are not subsequently enrolled will be maintained at the study site. 
All screening evaluations must be completed and reviewed to confirm that patients meet all 
eligibility criteria before enrollment. The investigator will maintain a screening log to record 
details of all patients screened, and to confirm eligibility or record reasons for screening failure, 
as applicable.

4.5.2 
Medical History, Concomitant Medication, and 
Demographic Data 
Medical history, including clinically significant diseases, surgeries, cancer history (including prior 
cancer therapies and procedures), and reproductive status will be recorded at baseline. In 
addition, all medications (e.g., prescription drugs, over-the-counter drugs, vaccines, herbal or 
homeopathic remedies, nutritional supplements) used by the patient within 14 days prior to 
initiation of study treatment will be recorded. At the time of each follow-up physical examination, 
an interval medical history should be obtained and any changes in medications and allergies 
should be recorded. 
Further, to assess the actual intake of anti-diarrheal medication use, patients will complete a 
medication diary each day. Patients will receive the diary on the first day of each cycle, with site 
staff completing information on any prescribed anti-diarrheal medications, including the 
recommended dosage and route of administration. Patients should use the diary to record daily 
ipatasertib dosing and specifically any anti-diarrheal medications used (prescribed or over-the-
counter) taken on that cycle of treatment. The intake of antidiarrheal medication will be reported 
in eCRF. Demographic data will include age, sex, and self-reported race/ethnicity. 
 
4.5.3 
Physical Examinations 
A complete physical examination, performed at screening and other specified visits, should 
include an evaluation of the head, eyes, ears, nose, and throat, and the cardiovascular, 
dermatological, musculoskeletal, respiratory, gastrointestinal, and neurological systems. Any 
abnormality identified at baseline should be recorded in the General Medical History and 
Baseline Conditions eCRF. 
Limited, symptom-directed physical examinations should be performed at specified post-
baseline visits and as clinically indicated. Changes from baseline abnormalities should be 
recorded in patient notes. New or worsened clinically significant abnormalities should be 
recorded as adverse events on the Adverse Event eCRF. 
4.5.4 
Vital Signs 
Vital signs will include measurements of pulse rate, and systolic and diastolic blood pressure 
while the patient is in a seated position after resting for at least 5 minutes, respiratory rate and 
oral, axillary or tympanic temperature. 
On paclitaxel dosing days, vital signs should be recorded prior to dosing and at the end 
of the infusion. 
4.5.5 
Tumor and Response Evaluations 
Patients will undergo tumor assessments with CT scan (with oral and IV contrast) of 
chest, abdomen, pelvis and bone scan of at baseline, every 3 cycles(12 weeks) (bone 
scan only if indicated) following treatment initiation regardless of dose delays, until 
radiographic disease progression per RECIST v1.1 or loss of clinical benefit as 
determined by the investigator (see Section 3.1 for details).  Protocol specific 
procedures will not be completed on 

Page 54 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
54 
patients who are no longer on the study. 
 
All measurable and evaluable lesions should be assessed and documented at screening. Tumor 
assessments performed as standard of care prior to obtaining informed consent and within 35 
days prior to initiation of study treatment do not have to be repeated at screening.  
Screening assessments must include CT scans (with oral or IV contrast) of chest, abdomen, 
pelvis, bone scan and MRI of brain with contrast. If a CT scan with contrast is contraindicated 
(i.e., in patients with contrast allergy or impaired renal clearance), a non-contrast CT scan of the 
chest may be performed and MRI scans of the abdomen, pelvis, and head should be performed. 
MRI scan of the brain must be done at screening to evaluate CNS metastasis in all 
patients (CT brain with contrast can be performed if MRI is contraindicated). At the 
investigator’s discretion, other methods of assessment of measurable disease as per RECIST 
v1.1 may be used. 
If a CT scan for tumor assessment is performed in a positron emission tomography (PET)/CT 
scanner, the CT acquisition must be consistent with the standards for a full-contrast diagnostic 
CT scan. 
All measurable and evaluable lesions should be re-assessed at each subsequent tumor 
evaluation. The same radiographic procedures used to assess disease sites at screening 
should be used for subsequent tumor assessments (e.g., the same contrast protocol for 
CT scans). 
Response will be assessed by the study radiologist using RECIST v1.1 (see Appendix 6). 
Assessments should be performed by the same evaluator, if possible, to ensure internal 
consistency across visits. Results must be reviewed by the investigator before dosing at the 
next cycle. 
An objective response should be confirmed by repeat assessments ≥4 weeks after initial 
documentation. At the investigator’s discretion, and if clinically indicated, CT scans may be 
repeated at any time if progressive disease is suspected, and other methods of assessment of 
measurable disease may be used (e.g., brain scans using CT or MRI) in addition to those listed 
above. For symptomatic deterioration attributed to disease progression, every effort should be 
made to document progression through use of objective criteria per RECIST v1.1. 
 
4.5.6 
Laboratory, Biomarker, and Other Biological 
Samples 
Laboratory samples should be drawn according to the study calendar (see 
Appendix 1) and within 48 hour prior to study drug administration. 
 
The following tests are required for Day 1 dosing for every cycle: CBC, differential; 
Comprehensive metabolic panel including glucose, creatinine, potassium, calcium, total 
bilirubin, ALP (total ALP), AST, ALT. Amylase, lipase, and thyroid test every other cycle.

Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
55 
Screening local laboratory assessments obtained within 96 hours before C1D1 do not have to 
be repeated for C1D1.  
Screening labs include: 
• 
Hematology: WBC count, RBC count, hemoglobin, hematocrit, platelet count, differential 
count (neutrophils, eosinophils, basophils, monocytes, lymphocytes, other cells) 
• 
Chemistry panel (serum or plasma): sodium, potassium, magnesium, chloride, bicarbonate, 
glucose, BUN or urea, creatinine, total protein, albumin, phosphorus, calcium, total bilirubin, 
alkaline phosphatase, ALT, AST, LDH 
• 
Coagulation: INR, aPTT 
• 
Fasting lipid profile (total cholesterol, high-density lipoprotein, low-density lipoprotein, 
triglycerides)  
• 
Glycosylated hemoglobin (HbA1c 
• 
Thyroid function testing:  thyroid-stimulating hormone, free triiodothyronine (T3) (or total T3 
for sites where free T3 is not performed), and free thyroxine (also known as T4) 
• 
Urinalysis  
• 
Pregnancy test: All women of childbearing potential will have a serum pregnancy test at 
screening. A woman is considered to be of childbearing potential if she is post-menarcheal, 
has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no 
identified cause other than menopause), and has not undergone surgical sterilization 
(removal of ovaries and/or uterus). 
• 
Screening viral serology: HBsAg, total hepatitis B core antibody (HBcAb), HCV 
antibody; additional tests for HBV DNA or HCV RNA will be required to confirm eligibility in 
patients with a positive antibody result. 
 
• 
HIV serology: HIV-1/2 antibody 
• 
Correlative Peripheral Blood sample such as plasma or PBMC will be collected for 
exploratory research on biomarkers at baseline, C2D1, C4D1and end-of-treatment visit. 
• 
Plasma Calprotectin will be collected at baseline, C2D1, C4D1 and end-of-treatment visit. 
• 
Stool microbiome will be collected at baseline, C4D1 and end-of-treatment visit. 
• 
Archival or newly collected tumor tissue sample obtained at baseline for determination of 
PIK3CA/AKT1/PTEN status and for exploratory research on biomarkers 
A representative FFPE tumor specimen in a paraffin block (preferred) or at least 
20 slides containing unstained, freshly cut, serial sections must be submitted along 
with an associated pathology report prior to study enrollment.  
Tumor tissue should be of good quality based on total and viable tumor content. 
Samples must contain a minimum of 30% tumor volume that preserve cellular context 
and tissue architecture regardless of needle gauge or retrieval method. Samples 
collected via resection, core-needle biopsy (at least three 18 gauge cores, 
embedded in a single paraffin block), or excisional, incisional, punch, or forceps 
biopsy are acceptable. Fine-needle aspiration (defined as samples that do not 
preserve tissue architecture and yield cell suspension and/or smears), brushing, cell 

Page 56 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
56 
pellets from pleural effusion, and lavage samples are not acceptable. Tumor tissue 
from bone metastases that have been decalcified are not acceptable. 
If archival tumor tissue is unavailable or is determined to be unsuitable for 
required testing, a pretreatment tumor biopsy is required. Patient should be 
encouraged to have repeat tumor biopsy at time of progression, if deemed clinically 
feasible, for exploratory research on biomarkers and study of potential 
molecular mechanisms of resistance. 
Biopsies at the time of progression should be performed within 40 days after progression or 
prior to the next anti-cancer therapy, whichever is sooner. Samples collected via resection, 
core-needle biopsy (at least three 18 gauge needle cores preferred), or excisional, incisional, 
punch, or forceps biopsy are acceptable. 
Exploratory biomarker research may include, but will not be limited to:  
• 
Somatic mutations and copy-number variations by NGS or PCR-based methods in tumor 
tissue and ctDNA 
• 
Expression analysis (e.g., RNA-Seq) of genes related to PI3K/Akt pathway activity, immune 
infiltration/activation, apoptosis, and breast cancer biology (i.e., intrinsic subtypes) 
• 
Immunohistochemistry-based analysis or quantitative digital immunohistochemistry of tumor 
suppressors, such as PTEN, and markers of immune infiltration and activation, such as 
CD8 and PD-L1 
NGS may be performed by Foundation Medicine or other NGS platform. If performed by 
Foundation Medicine or other CLIA-certified NGS platform, the investigator can obtain results 
from these analyses in the form of an NGS report. If allowed by local IRB, the investigator may 
share and discuss the results with the patient if the assay is CLIA-certified, unless the patient 
chooses otherwise. Results may not be available for samples that do not meet testing criteria. 
 
When a patient withdraws from the study, samples collected prior to the date of withdrawal may 
still be analyzed, unless the patient specifically requests that the samples be destroyed or local 
laws require destruction of the samples. 
Given the complexity and exploratory nature of the analyses, data derived from whole genome 
sequencing (WGS), whole exome sequencing (WES) or partial exome sequencing (PES) of 
specimens will generally not be provided to patients. 
Electrocardiograms and echocardiogram 
An ECG and echocardiogram is required at screening and when clinically indicated. ECG 
recordings must be performed after the patient has been resting in a supine position for at least 
10 minutes. For safety monitoring purposes, the investigator must review, sign, and date all 
ECG tracings. Paper copies of ECG tracings will be kept as part of the patient's permanent 
study file at the site. Any morphologic waveform changes or other ECG abnormalities must be 
documented in the patient’s medical records.

4.5.7 
Patient-Reported Outcomes  
To more fully characterize the clinical profile of ipatasertib, PRO data will be obtained through 
use of the following questionnaires: European Organization for Research and Treatment of 
Cancer (EORTC) quality-of-life questionnaire for cancer (EORTC QLQ-C30). The 
questionnaires will be translated as appropriate into the local language.  
To ensure instrument validity and that data standards meet health authority requirements, 
questionnaires scheduled for administration during a clinic visit will be completed in their entirety 
by the patient before the patient receives any information on disease status and prior to the 
performance of non-PRO assessments and the administration of study treatment.  
Patients who discontinue study treatment for any reason other than progressive disease or loss 
of clinical benefit will complete the EORTC QLQ-C30 questionnaire at each tumor assessment 
visit until radiographic disease progression per RECIST v1.1. 
All patients will complete the EORTC QLQ-C30 questionnaire at 3 and 6 months after 
radiographic disease progression per RECIST v1.1. 
4.5.7.1 
EORTC QLQ-C30 
The EORTC QLQ-C30 is a validated, reliable self-report measure (Aaronson et al. 1993; 
Fitzsimmons et al. 1999) (see Appendix 11). It consists of 30 questions that assess five 
aspects of patient functioning (physical, emotional, role, cognitive, and social), three symptom 
scales (fatigue, nausea and vomiting, pain), global health/quality of life, and six single items 
(dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties) with a recall 
period of the previous week. Scale scores can be obtained for the multi-item scales. 
The EORTC QLQ-C30 module takes approximately 10 minutes to complete.  
4.5.8 
Mandatory Samples for Circulating Tumor DNA  
Blood sampled will be collected for DNA extraction to enable whole genome sequencing (WGS), 
whole exome sequencing (WES) or partial exome sequencing (PES) to identify germline 
mutations and/or somatic mutations that are predictive of response to study drug, are 
associated with progression to a more severe disease state, are associated with acquired 
resistance to study drug, are associated with susceptibility to developing adverse events, or can 
increase the knowledge and understanding of disease biology. The blood samples may be sent 
to one or more laboratories for analysis. 
Genomics is increasingly informing researcher's understanding of disease pathobiology. WGS 
provides a comprehensive characterization of the genome and WES provides a comprehensive 
characterization of the exome and, along with clinical data collected in this study, may increase 
the opportunity for developing new therapeutic approaches. Data will be analyzed in the context 
of this study but will also be explored in aggregate with data from other studies. The availability 
of a larger dataset will assist in identification of important pathways, guiding the development of 
new targeted agents.

For sampling procedures, storage conditions, and shipment instructions, see Section 8   & and 
Appendix 10. 
Blood samples collected for WGS/WES/PES are to be stored until they are no longer needed or 
until they are exhausted.  
Patient medical information associated with WGS/WES/PES specimens is confidential and may 
be disclosed to third parties only as permitted by the Informed Consent Form (or separate 
authorization for use and disclosure of personal health information) signed by the patient. 
Given the complexity and exploratory nature of the circulating tumor DNA and WGS/WES/PES 
analyses, data derived from these analyses will generally not be provided to patients. 
4.5.9 
Post-Treatment Follow-Up  
All participants will enter follow-up after completing End-of-Treatment assessments. This is 
comprised of: 
• 
Safety Follow-up- 30 days post-last dose of protocol therapy. 
• 
Note the period for safety follow-up will be extended until stabilization or resolution for all 
reportable AEs (per the agreement of the Study PI) and accompanying follow-up safety 
report. 
• 
Response Follow-up- for those who have yet to have disease progression. 
• 
Survival Follow-up- for all participants who have progressed OR completed Active 
Response Follow-Up.  
• 
Assessment timepoints and windows are detailed in Appendix 1 Study Calendar. 
 
At post-treatment follow-up visits, survival follow-up information, subsequent treatment and 
outcome, and PROs will be collected via telephone calls, patient’s medical records, and/or clinic 
visits approximately every 3 months until death, loss to follow-up, or study termination by 
Sponsor. All patients will be followed for post-treatment follow-up information unless the patient 
requests to be withdrawn from study post-treatment follow-up; this request must be documented 
in the source file and signed by the investigator. 
 
For patients who discontinue treatment without evidence of disease progression per RECIST 
v1.1, in addition to post-treatment follow-up, patients will be followed every 12 weeks for tumor 
assessments (disease follow-up clinic visits; see Study Calendar Appendix 1) until documented 
progression per RECIST v1.1, elective withdrawal from the study, or study completion or 
termination.  
 
4.6 
DURATION OF THERAPY, CRITERIA OF REMOVAL FROM STUDY, 
PATIENT, AND STUDY DISCONTINUATION 
Patients must permanently discontinue study treatment (ipatasertib and carboplatin or 
carboplatin/paclitaxel) if they experience any of the following: 
• 
Any medical condition that the investigator or Sponsor determines may jeopardize the 
patient’s safety if he or she continues to receive study treatment 

Page 59 of 172

Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
59 
• 
Investigator or Sponsor determines it is in the best interest of the patient 
• 
Withdrawal of consent from the study treatment 
• 
Pregnancy 
• 
Use of an anti-cancer therapy not required per protocol 
• 
Disease progression per investigator’s assessment according to RECIST v1.1 or 
symptomatic deterioration attributed to disease progression 
 
The primary reason for study treatment discontinuation should be documented in the patient’s 
medical records.  
Patients will return to the clinic for a treatment discontinuation visit ≤ 30 days after the last dose 
of study treatment. The visit at which response assessment shows progressive disease may be 
used as the treatment discontinuation visit. Patients who discontinue study treatment for any 
reason other than progressive disease or loss of clinical benefit will continue to undergo tumor 
response assessments and PRO assessments as outlined in the schedule of activities (see 
Appendix 1). 
After treatment discontinuation, information on survival follow-up and new anti-cancer therapy 
will be collected via telephone calls, patient medical records, and/or clinic visits approximately 
every 3 months until death (unless the patient withdraws consent or the Investigator terminates 
the study). 
4.6.1 
Patient Discontinuation from Study 
Patients have the right to voluntarily withdraw from the study at any time for any reason. Patient 
will remain treatment on the study unless at least one of the following criteria was met: 
• 
Confirmed disease progression  
• 
Completed protocol therapy  
• 
Completion of study activities (treatment and overall survival follow-up after protocol 
treatment) 
• 
Participant is deemed intolerant to protocol therapy because of toxicity, despite dose 
modification/ delay  
o Note: If one agent is discontinued due to toxicity, then the participant may 
continue to receive the other study agents  
• 
General or specific changes in the patient's condition which render the patient unacceptable 
for further treatment in the judgment of the investigator 
• 
Study termination or site closure 
• 
Patient non-compliance, defined as failure to comply with protocol requirements as 
determined by the Investigator 
• 
Investigator or Sponsor determines it is in the best interest of the patient

• 
Withdrawal of consent for further protocol therapy (Refer to Withdrawal Section from Ethical 
Considerations) 
• 
Participant is lost to follow-up. All attempts to contact the participant must be documented. 
• 
At the discretion of the investigator for safety, behavioral, study termination or 
administrative reasons 
Once participants meet criteria for removal from protocol therapy, the participant should then 
proceed to End of Treatment assessments, and then to follow-up (Section 4.3). 
Documentation of the reason for discontinuing protocol therapy and the date effective should be 
made in the Electronic Health Record/medical record and appropriate eCRF. The COH DCC 
and the Study PI should be promptly notified of the change in participant status. 
 
Every effort should be made to obtain information on patients who withdraw from the study. The 
primary reason for withdrawal from the study should be documented in the patient’s medical 
records. If a patient requests to be withdrawn from the study, this request must be documented 
in the source documents and signed by the investigator. Patients who withdraw from the study 
prematurely will be replaced. 
If a patient withdraws from the study, the study staff may use a public information source 
(e.g., county records) to obtain information about survival status. 
4.6.2 
Study Discontinuation 
The Investigator has the right to terminate this study at any time. Reasons for terminating the 
study may include, but are not limited to, the following: 
• 
The incidence or severity of adverse events in this or other studies indicates a potential 
health hazard to patients 
• 
Patient enrollment is unsatisfactory 
Documentation of the reason for discontinuing study participation and the date effective should 
be made in the Electronic Health Record/medical record and appropriate eCRF. The COH DCC 
should be promptly notified of the change in participant status. 
 
 
5. 
ASSESSMENT OF SAFETY 
5.1 
SAFETY PLAN 
Ipatasertib is not currently approved for any indication, and clinical development is 
ongoing. The safety plan for patients in this study is based on clinical experience with 
ipatasertib in completed and ongoing studies. 
 
The anticipated important safety risks and management plan for ipatasertib and 
paclitaxel are outlined below. The identified risks associated with ipatasertib treatment 
include gastrointestinal toxicities (diarrhea, nausea, vomiting, and oral mucositis), 
fatigue/asthenia, erythema multiforma, rash, and hyperglycemia. Refer to the Ipatasertib 
Investigator's 

Page 61 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
61 
Brochure for a complete summary of safety information of ipatasertib as a single-agent 
and in combination with chemotherapy and other anticancer therapies. Refer to the 
Carboplatin and Paclitaxel Prescribing Information or Summary of Product Characteristics for a 
complete summary of safety information. 
 
Several measures will be taken to ensure the safety of patients participating in this study. 
Eligibility criteria have been designed to exclude patients at higher risk for toxicities. 
Patients will undergo safety monitoring during the study, including investigator’s 
assessment of the nature, frequency, and severity of adverse events, as well as 
expedited reporting of protocol-defined adverse events of special interest regardless of 
seriousness. Vital signs and relevant laboratory values will be monitored at baseline and 
during the study. 
 
Guidelines for managing adverse events, including prophylaxis (for diarrhea), and 
criteria for dose modification (interruption, dose reduction or discontinuation) for the 
management of specific adverse events attributable to ipatasertib, paclitaxel and carboplatin are 
summarized in Section 5.  
 
Suggested dose reductions for ipatasertib, carboplatin and paclitaxel are 
listed in rm A and Arm B. General guidelines for dose modification are provided in Table 1, 2, 
3 & 4. 
COH DSMC will be used during this study for toxicity monitoring. For details, refer to Section 6: 
Data & Safety Monitoring Plan, Adverse Event and Unanticipated Problem Reporting 
 
5.1.1 
Risks Associated with Ipatasertib in Combination with Paclitaxel 
Ipatasertib in combination with paclitaxel was administered to 61 cancer patients in 
Study GO29227 (LOTUS). Adverse events related to ipatasertib/placebo whose incidences 
were higher by ≥10% in patients receiving ipatasertib + paclitaxel versus 
placebo + paclitaxel were diarrhea (88.5% vs. 16.1%) and nausea (41.0% vs. 19.4%). 
The most frequent Grade ≥3 adverse events (reported in ≥ 5% of patients in either 
treatment arm) in patients in the ipatasertib + paclitaxel arm vs. placebo + paclitaxel arm 
were diarrhea (14 patients [23.0%], all Grade 3, vs. 0 patients), neutropenia (6 patients 
[9.8%] vs. 1 patient [1.6%]), decreased neutrophil count (5 patients [8.2%] vs. 4 patients 
[6.5%]), and fatigue (2 patients [3.3 %] vs. 4 patients [6.5%]), respectively. 
 
The incidence of overall neutropenia in the LOTUS Study was similar in both arms (34% 
in the ipatasertib + paclitaxel arm vs. 39% in the placebo +paclitaxel arm), but Grade ≥3 
neutropenia, analyzed by grouped terms of similar medical concept, was higher in the 
ipatasertib + paclitaxel arm (18% vs. 8%). Thus, for recurrent Grade ≥ 3 neutropenia, 
ipatasertib should be reduced by one dose level when treatment is restarted (refer to the 
Adverse Events Management Guidelines in Section 5.1.5.7). 
 
Refer to the Ipatasertib Investigator’s Brochure for further information regarding the 
nonclinical and clinical safety evaluation of ipatasertib as a single agent and in 
combination with chemotherapy.

5.1.2 
Risks Associated with Ipatasertib  
Hyperglycemia, including cases of Grade 3 or Grade 4 hyperglycemia, has been reported in 
patients receiving ipatasertib as monotherapy or ipatasertib in combination with other anticancer 
drugs or hormonal therapy. Hyperglycemia of any grade, regardless of causality, was reported 
in 35.3% of patients who received ipatasertib as a single agent in the Phase I Study PAM4743g, 
with Grade 3 hyperglycemia occurring in 1 patient (2.0%). In the GO27983 study, hyperglycemia 
of any grade, regardless of causality, was reported in 22.6%, 9.1%, and 7.4% of patients in the 
ipatasertib 400 mg, 200 mg, and placebo arms, respectively. Grade 3 hyperglycemia occurred 
in 10.7%, 2.3%, and 2.5% of patients in the 400 mg, 200 mg, and placebo arms, respectively. 
One patient (1.2%) in the ipatasertib 400 mg arm experienced Grade 4 hyperglycemia. There 
were no other instances of Grade 4 or higher hyperglycemia events in any arm. In the GO29227 
study, hyperglycemia of any grade, regardless of causality, was reported in 9.5% and 3.3% of 
patients in the ipatasertib 400 mg and placebo arms, respectively. There were no reports of 
Grade ≥3 hyperglycemia. 
GI toxicities such as nausea, vomiting, diarrhea, and stomatitis/oral mucositis have been 
commonly observed in patients receiving ipatasertib as monotherapy or in combination with 
other anticancer drugs.GI toxicities of any grade, regardless of causality, were commonly 
reported in patients who received ipatasertib as a single agent in the Phase I Study PAM4743g, 
including nausea (78.4%), diarrhea (72.5%), vomiting (58.8%), and stomatitis or mucosal 
inflammation (7.8%). In this study, the reported Grade 3 GI toxicities included diarrhea (7.8%), 
and nausea (2.0%). In the GO27983 study, GI toxicities, irrespective of grade or causality 
(presented by proportion of patients affected in the ipatasertib 400 mg, ipatasertib 200 mg, and 
placebo arms, respectively), included diarrhea (77.4%, 48.9%, and 24.7%), nausea (53.6%, 
35.2%, and 24.7%), vomiting (32.1%, 27.3%, and 14.8%), and oral mucositis (6.0%, 3.4%, and 
1.2%). The only Grade 3 GI AEs that affected ≥ 2 patients, irrespective of causality, were 
diarrhea (13.1%, 2.3%, and 1.2%) and nausea (2.4%, 0%, and 0%). There were no Grade 4 or 
5 events in this category in this study. In the GO29227 study, GI toxicities of any grade, 
regardless of causality, reported in the ipatasertib 400 mg and placebo arms, respectively, 
included diarrhea (92.1% and 20.0% ), nausea (52.4% and 33.3%), vomiting (27.0% and 
23.3%), and oral mucositis (23.8% and 15.0%). Grade 3 diarrhea occurred in 22.2% of the 
ipatasertib 400 mg arm and 0% of the placebo arm. Grade 3 vomiting was reported in 3.2% and 
0% of the ipatasertib 400 mg and placebo arms, respectively. With regard to Grade 3 nausea 
and Grade 3 oral mucositis, there was 1 patient in each arm (1.6% and 1.7% in the ipatasertib 
400 mg and placebo arms, respectively). There were no Grade 4 or Grade 5 diarrhea, nausea, 
vomiting, or oral mucositis events in any arm. 
Rash, primarily manifested as maculopapular type with or without pruritus, has been commonly 
reported in patients receiving treatment with ipatasertib. Rash-related events of any grade, 
regardless of causality, were reported in 15.7% of patients who received ipatasertib as a single 
agent in the Phase I Study PAM4743g; Grade 3 rash (toxic skin eruption as reported term) was 
reported in 1 patient (2.0%). In the GO27983 study, irrespective of grade or causality, the 
proportion of patients experiencing a rash-related event was 23.8%, 9.1%, and 6.2% in the

ipatasertib 400 mg, 200 mg, and placebo arms, 9.5%, 2.3%, and 0%, experienced Grade 3 
rash, respectively. One patient (1.2%) in the ipatasertib 400 mg arm experienced a Grade 4 
event. There were no other instances of Grade ≥4 events in this study. In the GO29227 study, 
rash of any grade, regardless of causality, was reported in 30.2% and 30.0% of the ipatasertib 
400 mg and placebo arms, respectively. There was 1 patient with Grade 3 rash in each arm 
(1.6% and 1.7% in the ipatasertib 400 mg and placebo arms, respectively). There were no 
cases of Grade 4 or Grade 5 rash events in any arm. Cases of Grade 3 rash requiring dose 
interruption and treatment with topical or systemic corticosteroids have also been observed from 
other ongoing ipatasertib studies. In addition, cases of erythema multiforma have been 
identified, 
Fatigue or asthenia of any grade, regardless of causality, has been observed in 62.7% of 
patients receiving ipatasertib as a single agent in the Phase I Study PAM4743g, with 5 (9.8%) 
cases of Grade 3 asthenia/fatigue reported. In the GO27983 study, asthenia/fatigue of any 
grade, irrespective of causality, was reported in 48.8%, 45.5%, and 43.2% of patients in the 
ipatasertib 400 mg, 200 mg, and placebo arms, respectively. Grade 3 asthenia/fatigue occurred 
in 9.5%, 5.7%, and 3.7% of patients, respectively, as above. There were no cases of Grade 4 or 
Grade 5 asthenia/fatigue events in any arm. In the GO29227 study, asthenia/fatigue of any 
grade, regardless of causality, was reported in 49.2% and 43.3% of the ipatasertib 400 mg and 
placebo arms, respectively. Grade 3 asthenia/fatigue was reported in 6.3% and 6.7% of the 
ipatasertib 400 mg and placebo arms, respectively. There were no cases of Grade 4 or Grade 5 
asthenia/fatigue events in any arm.

5.1.5.2 
Dose Modifications 
The five agents included in this study (ipatasertib, carboplatin, paclitaxel, capecibabine, 
atezolizumab) have overlapping and non-overlapping toxicity profiles. Neuropathy is likely 
attributed to paclitaxel. Nausea, vomiting, myelosuppression and infusion reaction can be 
attributed by both paclitaxel and carboplatin. Diarrhea and stomatitis can be attributed by 
ipatasertib, capecitabine and paclitaxel. Premedication such as dexamethasone and ipatasertib 
can both cause hyperglycemia. Nausea, vomiting and myelosuppression can be contributed by 
all three agents.  
Guidelines for dosage modification and treatment interruption or discontinuation are provided 
below. 
 
Any dose interruption, dose modification, overdose or incorrect administration of study druges 
should be noted on the corresponding study drug administration eCRF. All adverse events 
associated with an overdose or incorrect administration of study druges should be recorded on 
the Adverse Event log eCRF. 
 
 
5.1.5.3 
Dose Modification General Guidelines 
Details in this section can be used as guidance for dose modification. Only the specific dose 
levels shown should be used (Table 1, Table 2 , Table 3 and Table 4).  
 
Reasons for dose modifications (interruption or reduction) and discontinuation, the supportive 
measures taken, and the outcome will be documented in the patient's chart and recorded in the 
eCRF. Reasons for not adhering to the following guidance should also be documented in the 
patient’s chart. 
 
On day 1 of each cycle of treatment, the general parameters for chemotherapy administration 
include the following: 
• 
ANC ≥ 1500/µl (≤Gr 1) 
• 
Hemoglobin ≥ 8mg/dL * 

Page 68 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
68 
• 
Platelet count ≥ 100,000/µL (≤Gr 1) 
• 
Grade ≤ 2 clinically significant chemotherapy-related gastrointestinal toxicity or neuropathy 
 
On the day 8 & 15 each cycle of treatment, the general parameters for chemotherapy 
administration include the following: 
• 
ANC ≥ 1000/µl (≤Gr 2) 
• 
Hemoglobin ≥ 8 mg/dL* 
• 
Platelet count ≥ 75,000/µL(≤Gr 2) 
• 
Grade ≤ 2 clinically significant chemotherapy-related gastrointestinal toxicity or neuropathy 
* Transfusion allowed on treatment day to meet the hemoglobin criteria 
 
General guidelines for dosage/schedule modification are summarized as follows: 
• 
If any treatment component is held or delayed, the study cycle day count continues and 
does not shift except day 1 of each cycle; i.e., every cycle contains exactly 28 days. 
• 
If ipatasertib treatment is interrupted during the middle of a cycle, carboplatin or 
carbo/paclitaxel treatment should continue. 
• 
If day 1 of the cycle is interrupted, consider delaying the ipatasertib and chemotherapy 
treatment concurrently for up to 7 days to maintain the 28 day cycle 
• 
If day 8 or 15 of the cycle is interrupted, no makeup dose of chemotherapy treatment will be 
given. 
• 
If toxicity causes chemotherapy to be omitted, patient should be seen in one week for 
lab/adverse events follow up/treatment. 
• 
Once the toxicity has resolved to the required level, study treatment and study procedures 
will be resumed. No makeup doses of day 8 or day 15 carboplatin/paclitaxel will be given. 
• 
For any concomitant conditions at baseline, dose modifications may apply according to the 
shift in toxicity grade, if the investigator deems it appropriate. For example, if a patient has 
Grade 1 asthenia at baseline that increases to Grade 2 during treatment, this change may 
be considered a shift of one grade and may be treated as Grade 1 toxicity for dose-
modification purposes if medically appropriate. 
• 
For toxicities assessed by the investigator to be unrelated to study treatment and unlikely to 
develop into serious or life-threatening events, treatment may be continued at the same 
dose without reduction or interruption. 
• 
Dose reductions or interruptions may not be required for anemia (non-hemolytic) if 
satisfactorily managed by transfusions. 
• 
If any observed toxicity is attributable to only one drug as assessed by the investigator, the 
dose of the other drug(s) may not require modification. 
• 
Dose modifications for isolated abnormal hematologic laboratory values will be based on 
hematologic parameters at the start of a treatment cycle. 
• 
Chemotherapy may be interrupted to manage toxicity.

• 
 
A dosing gap of up to 4 consecutive weeks (approximately 28 days) is permitted. 
 
Any dose hold for longer than 4 weeks for a treatment-related adverse event will require 
permanent discontinuation of the attributable treatment component and per specific 
Adverse Event Management Guidelines in Section 5.1.5.7. As applicable, patients should 
continue treatment either on carboplatin or carboplatin/paclitaxel alone, or may continue 
treatment with ipatasertib alone after discussing with the principle investigator. 
 
5.1.5.4 
Dose Modifications for Carboplatin

Associated with Carboplatin 
Event 
Action to Be Taken 
General guidance for treatment 
delays and discontinuation 
• When a treatment cycle is delayed because of a toxicity 
resulting from any component of the regimen, all study 
treatment should generally be withheld and resumed 
together to remain synchronized. 
• If one drug is discontinued, treatment with the other drugs 
may be continued for patients experiencing clinical benefit as 
determined by the investigator. 
• Permanently discontinue study treatment if an adverse event 
requires treatment to be withheld for > 28 days. 
IRRs and anaphylaxis 
• Guidelines for management of IRRs are provided in section 
5.1.5.7.9  
Hematologic toxicity 
 
Grade 2 Neutropenia 
• Hold treatment for D1 of each cycle till ANC ≥ 1.5 
• Continue study treatment for Days 8 or 15. 
• Growth factor can be given  
Grade 3 Neutropenia 
• Withhold study treatment. 
• Give supportive treatment. 
• If event resolves to Grade 2 or better, resume study 
treatment. 
• 1st episode, reduce by one dose level see table 2 & 3 and 
use G-CSF support 
• 2nd episode of G3 neutropenia despite adequate use of G-
CSF support, discontinue day 15 dose of carboplatin 3rd

• Withhold study treatment. 
• Nausea and/or vomiting should be controlled with adequate 
antiemetic therapy. Prophylactic anti-emetic therapy can be 
used at the discretion of the treating physician. Patients are 
encouraged to take plenty of oral fluids. If symptoms persist 
despite maximal anti-emetic therapy, treatment should be 
withheld until recovery to ≤ grade 1 
Grade ≥3 Diarrhea 
• Withhold study treatment 
• Refer to management guideline for diarrhea in separate table 
• Resume treatment only if symptom recovery to ≤ grade 1 
Other Grade 3/4 Toxicities 
For any grade 3 or 4 toxicity not mentioned above, withhold drug 
until the patient recovers to grade 1 or less toxicity. The 
treatment should then be resumed at one lower dose level for 
carboplatin.

treatment-related toxicity, the treatment should be discontinued. Treatment may be 
suspended for reasons other than toxicity (e.g., surgical procedures) with investigator approval. 
If, in the judgment of the investigator, the patient is likely to derive clinical benefit from resuming 
study treatment after a hold of >28 consecutive days, study drug may be restarted. This applies 
to ipatasertib, carboplatin/paclitaxel or carboplatin. 
5.1.5.7 
Adverse Event Management Guidelines 
Guidelines for management of specific adverse events are provided in the subsections below. 
5.1.5.7.1 
Diarrhea Management Guidelines 
Specific guidelines for managing diarrhea to improve safety and tolerability are provided in 
Table 5. In this study, all patients should receive loperamide (2 mg oral twice a day or 4 mg 
once a day) as prophylaxis for diarrhea in the first cycle. Patients are encouraged to continue 
this dosing for the remainder of the study, and the prophylaxis dose may be adjusted as 
necessary, using their discretion based on clinical judgment and per local guidance.

Treatment modifications for diarrhea (any grade), when it occurs, should be instituted as early 
as possible. Guidelines for treatment of diarrhea following the prophylactic dose of loperamide 
(where allowed) includes use of loperamide 2 mg every 4 hours or after each loose, watery 
stool, up to the maximum total dose of 16 mg/day or per institutional guidelines and standard of 
care, including, but not limited to, additional therapy with Lomotil (diphenoxylate and atropine), 
codeine, or octreotide. Duration of diarrhea may be minimized by taking ipatasertib with food, 
avoiding lactose-containing foods, and hydrating with 8−10 glasses per day (~12 oz/glass) of 
electrolyte-containing clear liquid, such as broth or low-calorie drinks.  
For ≥ Grade 3 diarrhea that persists for more than 5 days, despite treatment with anti-diarrheal 
agent(s) and/or withholding dosing of ipatasertib, gastroenterologists should be consulted to rule 
out the risk of colitis and infection (e.g., obtaining CT images or a stool culture for infectious 
workup [Clostridium difficile, enteric bacteria, cytomegalovirus]). Patients should be educated on 
the symptoms and importance of early reporting of diarrhea to receive instructions of treatment 
and prevention of dehydration so that patients can be promptly and appropriately managed. 
Educational materials will be provided to investigators and patients outlining these guidelines.  
Dose intensity of paclitaxel should be maintained as tolerated. Dose reductions of ipatasertib 
will be by one level at a time (i.e., 400 to 300 mg; 300 to 200 mg) as outlined in Section 5.1.5.1 
and Table 2. . If Grade ≥ 2 diarrhea persists following dose reductions of ipatasertib 200 mg 
daily and with maximum treatment for diarrhea, ipatasertib should be discontinued

Fasting Hyperglycemia 
Fasting is defined as abstaining from food and drink (with the exception of water) for at least 8 
hours.  
Dose modification guidelines for fasting hyperglycemia attributable to study treatment are 
outlined below (see Table 6) and are intended to provide guidance for fasting glucose 
measurements assessed in the clinic. Decisions regarding study treatment should be made on 
fasting levels drawn in the clinic whenever possible. 
Home glucose measurements may be used to trigger contact between patient and investigative 
site team and may lead to an unscheduled clinic visit to assess fasting glucose. Guidance for

when to call the investigator/site staff (or designated endocrinologist, if applicable) should be 
provided to patients for hypoglycemia (e.g., glucose value under 70 mg/dL) and hyperglycemia 
(e.g., glucose value over 300 mg/dL). Alternative thresholds may be selected as clinically 
indicated per investigator discretion or institutional guidance and noted in the source 
documents. For any patients performing home glucose monitoring, the blood glucose log should 
be reviewed at each clinic visit (and source data retained), entry of results into the patient’s 
eCRF will be limited to values which result in intervention.  
In the event of ipatasertib interruption, anti-diabetic medications may need to be held or reduced 
(per investigator judgement) and glucose should be monitored closely to minimize the risk of 
hypoglycemia.

• 
If Grade ≥ 2 mucositis recurs in subsequent 4 week cycles, despite 
maximal supportive care, the dose of ipatasertib should be reduced by 
one dose level. The dose of capecitabine, carboplatin or 
carboplatin/paclitaxel may be maintained for subsequent cycle. 
Grade ≥ 3 
• 
Hold ipatasertib until recovery to Grade 2 or better. If the mucositis 
resolves to Grade 2 or better during the current cycle, the dose of 
ipatasertib should be reduced by one dose level. The dose of 
capecitabine, carboplatin or carboplatin/paclitaxel may be reduced for 
subsequent cycle per investigator’s discretion. 
• 
If recovery of mucositis to Grade 2 or better does not occur within a 
maximum of 4 weeks, the patient will permanently discontinue 
ipatasertib. 
 
5.1.5.7.8 
Peripheral Neuropathy 
If Grade ≥3 peripheral neuropathy attributable to paclitaxel develops in patients, 
paclitaxel should be held until the neuropathy recovers to Grade 2 or better, or 
resolution such that the peripheral neuropathy is no longer clinically significant. During 
this time, 
patients may continue ipatasertib/carboplatin.  
 
If the peripheral neuropathy recovers to Grade 2 or better within 4 weeks or resolution 
such that the peripheral neuropathy is no longer clinically significant, dosing of 
paclitaxel may resume reduced by one dose level (see Section 5.1.5.3).  
 
If recovery of the peripheral neuropathy to Grade 2 or better does not occur within a 
maximum of 4 weeks, the patient will permanently discontinue paclitaxel but may 
continue the ipatasertib/carboplatin. 
 
5.1.5.7.9 
Hypersensitivity Reactions 
If a hypersensitivity reaction due to infusion of paclitaxel or carboplatin develops in 
patients, treatment for the hypersensitivity reaction, including the possibility of 
rechallenging with the attributable chemotherapy agent, in presence of premedication for 
paclitaxel or carboplatin should be administered as per institutional guidelines or at the 
discretion of the investigator.  
 
Caution: Patients who had a mild to moderate hypersensitivity reaction have been 
successfully rechallenged, but careful attention to prophylaxis and bedside 
monitoring of vital signs is recommended.  
If patients develop severe allergy to paclitaxel despite adequate premedication, 
weekly nab-paclitaxel can be used to replace weekly paclitaxel following standard 
institutional practice after discussion with PI.

Subjects who have developed hypersensitivity reactions may undergo 
desensitization per institutional protocol. This should be discussed with the study 
PI. The patient may continue the other study treatment components not associated with 
the toxicity (i.e., ipatasertib or carboplatin or paclitaxel) 
 
Mild symptoms: (e.g., mild flushing, rash, pruritus) - Complete infusion. Supervise at 
bedside. No treatment required.  
 
Moderate symptoms: (e.g., moderate rash, flushing, mild dyspnea, chest discomfort) - 
Stop infusion. Give intravenous diphenhydramine 25 mg and intravenous 
dexamethasone 10 mg. Resume infusion after recovery of symptoms at a low rate, 20 
mg/hr. For 15 minutes, then, if no further symptoms, at full dose rate until infusion is 
complete. If symptoms recur, stop infusion. Record toxicity on flow sheets.  
 
Severe life threatening symptoms: (e.g., hypotension requiring pressor therapy, 
angioedema, respiratory distress requiring bronchodilation therapy, generalized urticaria) 
- Stop infusion. Give intravenous diphenhydramine and dexamethasone as above. Add 
epinephrine or bronchodilators if indicated. If wheezing is present, that is not responsive 
to bronchodilators, epinephrine is recommended. Patient should be removed from further 
protocol therapy. Report as an adverse event.  
 
5.1.5.7.10 Other Non-Hematologic Toxicities 
If other Grade ≥ 3 non hematologic toxicities not described above develop in patients, treatment 
with ipatasertib may be held, depending on the attribution of the toxicity, at the discretion of the 
investigator. During this time, treatment may continue with the other non-attributable treatment 
agent (i.e., either ipatasertib or carboplatin or carboplatin/paclitaxel). Grade ≥ 3 non-hematologic 
toxicity should be monitored at least weekly. 
If the toxicity resolves to Grade 1 or better within 2 weeks, treatment may resume with the 
attributable agent. 
If the toxicity resolves to Grade 1 or better in 2−4 weeks, the dose of the attributable drug 
should be reduced by one level per the suggested guidelines in Section 5.1.5.1. 
Depending on the nature and the severity of the adverse event, if recovery to Grade 1 or better 
takes > 4 weeks, treatment may resume with the attributable agent with dose reduction, or the 
attributable agent may be permanently discontinued, at the discretion of the investigator.  
5.1.5.7.11 Specific Management Guidelines for Arm 3 Atezolizumab Toxicities 
Toxicities associated or possibly associated with atezolizumab/placebo treatment should be 
managed according to standard medical practice. Although most immune-related adverse 
events observed with immunomodulatory agents have been mild and self-limiting, such events 
should be recognized early and treated promptly to avoid potential major complications.

Endocrine Events  
Thyroid disorders or adrenal insufficiency has been associated with the administration of 
atezolizumab. Management guidelines for endocrine events are provided in Table 5.1.5.7.11D.  
Patients with unexplained symptoms such as fatigue, myalgias, impotence, mental status 
changes, or constipation should be investigated for the presence of thyroid, pituitary, or adrenal 
endocrinopathies. The patient should be referred to an endocrinologist if an endocrinopathy is 
suspected. Thyroid-stimulating hormone (TSH) and free T3 and T4 levels should be measured 
to determine whether thyroid abnormalities are present. TSH, prolactin, and a morning cortisol 
level will help to differentiate primary adrenal insufficiency from primary pituitary insufficiency.

5.1.5.7.11.9 Management of meningoencephalitis 
Immune-related meningoencephalitis is an identified risk associated with the administration of 
atezolizumab. Immune-related meningoencephalitis should be suspected in any patient 
presenting with signs or symptoms suggestive of meningitis or encephalitis, including, but not 
limited to, headache, neck pain, confusion, seizure, motor or sensory dysfunction, and altered or 
depressed level of consciousness. Encephalopathy from metabolic or electrolyte imbalances 
needs to be distinguished from potential meningoencephalitis resulting from infection (bacterial, 
viral, or fungal) or progression of malignancy, or secondary to a paraneoplastic process.  
All patients being considered for meningoencephalitis should be urgently evaluated with a CT 
scan and/or MRI scan of the brain to evaluate for metastasis, inflammation, or edema. If 
deemed safe by the treating physician, a lumbar puncture should be performed and a 
neurologist should be consulted.  
 
Patients with signs and symptoms of meningoencephalitis, in the absence of an identified 
alternate etiology, should be treated according to the guidelines in Table 5.1.5.7.11.J.

Related Nephritis) 
Immune-related nephritis has been associated with the administration of atezolizumab. Eligible 
patients must have adequate renal function defined as baseline calculated creatinine clearance 
≥ 50 mL/min, and renal function will be monitored throughout study treatment. Patients with 
signs and symptoms of nephritis, in the absence of an identified alternate etiology, should be 
treated according to the guidelines in Table 5.1.5.7.11.K.  
For patients with elevated creatinine, concurrent medication, volume depletion, renal obstruction 
should be considered and addressed, as appropriate. Refer to a renal specialist if clinically 
indicated. A renal biopsy may be required to enable a definitive diagnosis and appropriate 
treatment.

5.1.5.7.11.11 Management of Immune-related myositis 
Immune-related myositis has been associated with the administration of atezolizumab. Myositis 
or inflammatory myopathies are a group of disorders sharing the common feature of 
inflammatory muscle injury; dermatomyositis and polymyositis are amongst the most common 
disorders. The diagnosis is based on clinical signs and symptoms (muscle weakness, muscle 
pain, skin rash in dermatomyositis) supported by confirmatory diagnostic studies such as 
biochemical markers (serum creatine-kinase increase), electromyography, and imaging (MRI) 
features, which may be confirmed with a muscle-biopsy. Patients presenting with muscle pain 
without muscle weakness should have atezolizumab held pending evaluation for possible 
myositis. Referral to a neurologist should be considered for patients presenting with weakness. 
Patients with symptoms and confirmation of myositis, in the absence of an identified alternate 
etiology, should be treated according to the guidelines in Table 5.1.5.7.11L.

limits mobility) and convert to 1-2 mg/kg/day oral prednisone or 
equivalent upon improvement.  
- If event does not improve within 48 hours after initiating 
corticosteroids, consider adding an immunosuppressive agent.  
- If event resolves to Grade 1 or better, taper corticosteroids 
over ≥ 1 month. 
 
5.1.5.7.11.12 Management of Immune-related cardiac toxicity 
Cardiac toxicity is a potential toxicity with the use of atezolizumab. Patients should be monitored 
for signs and symptoms of left ventricular dysfunction and cardiac arrhythmias. Consider 
echocardiogram and ECG. For Grade 2 symptomatic cardiac toxicities refer to cardiologist for a 
cardiac evaluation. Consider endomyocardial biopsy and initiation of oral steroids. For Grade 3 
or Grade 4 cardiac toxicities, hospitalize, obtain a cardiology consult and obtain endomyocardial 
biopsy unless contraindicated. Treat with intravenous steroids followed by high dose oral 
steroids. See Table 5.1.5.7.11M for management of symptomatic cardiac toxicities related to 
atezolizumab.

6. GENENTECH ADVERSE EVENT REPORTING,  DATA & SAFETY MONITORING 
PLAN 
 
ASSESSMENT OF SAFETY 
 
Specification of Safety Variables 
 
Safety assessments will consist of monitoring and reporting adverse events (AEs) and serious 
adverse events (SAEs) per protocol. This includes all events of death, and any study specific 
issue of concern. 
 
Adverse Events 
 
An AE is any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational medicinal product 
(IMP) or other protocol-imposed intervention, regardless of attribution. 
 
This includes the following: 
•    AEs not previously observed in the subject that emerge during the protocol-
specified  
• 
AE reporting period, including signs or symptoms associated with metastatic breast cancer 
that were not present prior to the AE reporting period. 
• 
Complications that occur as a result of protocol-mandated interventions (e.g., 
invasive procedures such as cardiac catheterizations) 
• 
If applicable, AEs that occur prior to assignment of study treatment associated 

Page 97 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
97 
with medication washout, no treatment run-in, or other protocol-mandated 
intervention. 
• 
Preexisting medical conditions (other than the condition being studied) judged by 
the investigator to have worsened in severity or frequency or changed in 
character during the protocol-specified AE reporting period. 
 
Serious Adverse Events 
 
An AE should be classified as an SAE if the following criteria are met: 
• 
It results in death (i.e., the AE actually causes or leads to death). 
• 
It is life threatening (i.e., the AE, in the view of the investigator, places the subject at 
immediate risk of death. It does not include an AE that, had it occurred in a more severe 
form, might have caused death.). 
• 
It requires or prolongs inpatient hospitalization. 
• 
It results in persistent or significant disability/incapacity (i.e., the AE results in 
substantial disruption of the subject’s ability to conduct normal life functions). 
• 
It results in a congenital anomaly/birth defect in a neonate/infant born to a mother 
exposed to the IMP. 
• 
It is considered a significant medical event by the investigator based on medical 
judgment (e.g., may jeopardize the subject or may require medical/surgical intervention 
to prevent one of the outcomes listed above). 
 
METHODS AND TIMING FOR ASSESSING AND RECORDING SAFETY VARIABLES 
 
The investigator is responsible for ensuring that all AEs and SAEs that are observed or reported 
during the study are collected and reported to the FDA, appropriate IRB(s), and Genentech, Inc. 
in accordance with CFR. 
 
Adverse Event Reporting Period 
 
The study period during which AEs and SAEs as described in section J where the 
patient has been exposed to Genentech product must be reported Reporting period 
begins after informed consent is obtained and initiation of study treatment and 
ends 30 days following the last administration of study treatment or study 
discontinuation/termination, whichever is earlier. After this period, investigators 
should only report SAEs that are attributed to prior study treatment (Modify 
statement depending up on section g). 
 
Assessment of Adverse Events 
 
All AEs and SAEs whether volunteered by the subject, discovered by study 
personnel during questioning, or detected through physical examination, 
laboratory test, or other means will be reported appropriately. Each reported AE 
or SAE will be described by its duration (i.e., start and end dates), regulatory 
seriousness criteria if applicable, suspected relationship to the study drug (see 

Page 98 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
98 
following guidance), and actions taken. 
 
To ensure consistency of AE and SAE causality assessments, investigators 
should apply the following general guideline: 
 
Yes 
 
There is a plausible temporal relationship between the onset of the AE and 
administration of the study drug, and the AE cannot be readily explained by the 
subject’s clinical state, intercurrent illness, or concomitant therapies; and/or the 
AE follows a known pattern of response to the study drug; and/or the AE 
abates or resolves upon discontinuation of the study drug or dose reduction 
and, if applicable, reappears upon re- challenge. 
 
No 
 
Evidence exists that the AE has an etiology other than the {study drug} (e.g., 
preexisting medical condition, underlying disease, intercurrent illness, or 
concomitant medication); and/or the AE has no plausible temporal relationship 
to study drug administration (e.g., cancer diagnosed 2 days after first dose of 
study drug). 
 
Expected adverse events are those adverse events that are listed or 
characterized in current Investigator Brochure. 
 
Unexpected adverse events are those not listed in the P.I or current I.B or not 
identified. This includes adverse events for which the specificity or severity is not 
consistent with the description in the P.I. or I.B. For example, under this 
definition, hepatic necrosis would be unexpected if the P.I. or I.B. only referred to 
elevated hepatic enzymes or hepatitis. 
 
 
PROCEDURES FOR ELICITING, RECORDING, AND REPORTING ADVERSE 
EVENTS 
 
Eliciting Adverse Events 
 
A consistent methodology for eliciting AEs at all subject evaluation time points 
should be adopted. Examples of non-directive questions include: 
 
• 
“How have you felt since your last clinical visit?” 
• 
“Have you had any new or changed health problems since you were last 

Page 99 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
99 
here?” 
 
Specific Instructions for Recording Adverse Events 
 
Investigators should use correct medical terminology/concepts when 
reporting AEs or SAEs. Avoid colloquialisms and abbreviations. 
 
a.   Diagnosis vs. Signs and Symptoms 
 
If known at the time of reporting, a diagnosis should be reported rather than individual signs 
and symptoms (e.g., record only liver failure or hepatitis rather than jaundice, asterixis, and 
elevated transaminases). However, if a constellation of signs and/or symptoms cannot be 
medically characterized as a single diagnosis or syndrome at the time of reporting, it is 
acceptable to report the information that is currently available. If a diagnosis is subsequently 
established, it should be reported as follow-up information. 
 
b.   Deaths 
 
All deaths that occur during the protocol-specified AE reporting period (see Section I), 
regardless of attribution, will be reported to the appropriate parties. When recording a death, 
the event or condition that caused or contributed to the fatal outcome should be reported as the 
single medical concept. If the cause of death is unknown and cannot be ascertained at the time 
of reporting, report “Unexplained Death”. 
 
c.   Preexisting Medical Conditions 
 
A preexisting medical condition is one that is present at the start of the study. Such conditions 
should be reported as medical and surgical history. A preexisting medical condition should be 
re-assessed throughout the trial and reported as an AE or SAE only if the frequency, severity, or 
character of the condition worsens during the study. When reporting such events, it is important 
to convey the concept that the preexisting condition has changed by including applicable 
descriptors (e.g., “more frequent headaches”). 
 
d.   Hospitalizations for Medical or Surgical Procedures 
 
Any AE that results in hospitalization or prolonged hospitalization should be documented and 
reported as an SAE. If a subject is hospitalized to undergo a medical or surgical procedure as 
a result of an AE, the event responsible for the procedure, not the procedure itself, should be 
reported as the SAE. For example, if a subject is hospitalized to undergo coronary bypass 
surgery, record the heart condition that necessitated the bypass as the SAE. 
 
Hospitalizations for the following reasons do not require reporting: 
• 
Hospitalization or prolonged hospitalization for diagnostic or elective surgical 

Page 100 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
100 
procedures for preexisting conditions 
• 
Hospitalization or prolonged hospitalization required to allow efficacy measurement for 
the study or 
• 
Hospitalization or prolonged hospitalization for scheduled therapy of the target disease of 
the study 
e. Assessment of Severity of Adverse Events 
 
 
  
The adverse event severity grading scale for the NCI CTCAE (v5.0 Update current versions) will 
be used for assessing adverse event severity. Below Table should be used for assessing 
severity for adverse events that are not specifically listed in the NCI CTCAE. 
 
Table 12. Adverse Event Severity Grading Scale for Events Not Specifically Listed in NCI CTCAE 
Grade 
Severity 
1 
Mild; asymptomatic or mild symptoms; clinical or diagnostic 
observations only; or intervention not indicated 
2 
Moderate; minimal, local, or non-invasive intervention indicated; or 
limiting age-appropriate instrumental activities of daily living a 
3 
Severe or medically significant, but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; or 
limiting self-care activities of daily living b,c 
4 
Life-threatening consequences or urgent intervention indicated d 
5 
Death related to adverse event d 
NCI CTCAE = National Cancer Institute Common Terminology Criteria for Adverse Events. 
Note:  Based on the most recent version of NCI CTCAE (v5.0), which can be found at:  
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm 
a. Instrumental activities of daily living refer to preparing meals, shopping for groceries 
or clothes, using the telephone, managing money, etc. 
b. Examples of self-care activities of daily living include bathing, dressing and 
undressing, feeding oneself, using the toilet, and taking medications, as performed 
by patients who are not bedridden. 
c. If an event is assessed as a "significant medical event," it must be reported as a 
serious adverse event  
d. Grade 4 and 5 events must be reported as serious adverse events  
 
 
f. 
  Pregnancy 
 
If a female subject or the female partner of a male study subject becomes pregnant while 
receiving the study drug or within 5 months after the last dose of study drug, a report should be 
completed and expeditiously submitted to Genentech, Inc. Follow-up to obtain the outcome of 
the pregnancy should also occur. Abortion, whether accidental, therapeutic, or spontaneous, 
should always be classified as serious, and expeditiously reported as an SAE. Similarly, any 

Page 101 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
101 
congenital anomaly/birth defect in a child born to a female subject exposed to the study drug 
should be reported as an SAE. 
 
 
g. Post-Study Adverse Events  
 
For studies involving collection of survival data/ follow up until progression free period/ Extended 
follow up period (select applicable) the investigator after the end of the adverse event reporting 
period (defined as 30 days after the last dose of study drug) should report all deaths, 
(regardless of cause), and any serious adverse event including development of cancer or a 
congenital anomaly in a subsequently conceived offspring of a female subject who participated 
in the study that is believed to be related to prior exposure to study drug. 
Case Transmission Verification will be performed by both parties during this period to ensure 
successful transmission of Single case reports. 
 
The investigator should expeditiously report any SAE occurring after a subject has completed 
or discontinued study participation if attributed to prior study drug exposure. If the investigator 
should become aware of the development of cancer or a congenital anomaly in a 
subsequently conceived offspring of a female subject [add if applicable-including pregnancy 
occurring in the partner of a male study subject] who participated in the study, this should be 
reported as an SAE adequately to Genentech drug Safety during follow up period. 
 
 
h. Case Transmission Verification of Single Case Reports 
 
The Sponsor agrees to conduct  the Case Transmission verification to ensure that all single 
case reports have been adequately received by Genentech  via City of Hope emailing 
Genentech a Quarterly line-listing documenting single case reports sent by City of Hope to 
Genentech in the preceding time period.  
 
The periodic line-listing will be exchanged within seven (7) calendar days of the end of the 
agreed time period. Confirmation of receipt should be received within the time period mutually 
agreed upon. 
                    
If discrepancies are identified, the Sponsor and Genentech will cooperate in resolving the 
discrepancies. The responsible individuals for each party shall handle the matter on a case-by-
case basis until satisfactory resolution.  The sponsor shall receive reconciliation guidance 
documents within the ‘Activation Package’. 
 
Following Case Transmission Verification, single case reports which have not been received by 
Genentech shall be forwarded by City of Hope to Genentech within five (5) calendar days from 
request by Genentech. 
 
At the end of the study, a final cumulative Case Transmission Verification report will 
be sent to Genentech

REPORTING TO REGULATORY AUTHORITIES, ETHICS COMMITTEES AND 
INVESTIGATORS 
 
City of hope will be responsible for the distribution of safety information to its own investigators, 
where relevant 
 
Additional Reporting Requirements for IND Holders (if applicable):  
 
For Investigator-Initiated IND Studies, some additional reporting requirements for the FDA 
apply in accordance with the guidance set forth in 21 CFR § 
600.80. 
 
Events meeting the following criteria need to be submitted to the Food and Drug 
Administration (FDA) as expedited IND Safety Reports according to the following 
guidance and timelines: 
 
7 Calendar Day Telephone or Fax Report: 
 
The Investigator is required to notify the FDA of any fatal or life-threatening adverse event that 
is unexpected and assessed by the Investigator to be possibly related to the use of study 
drugs. An unexpected adverse event is one that is not already described in the study drugs 
Investigator Brochure. Such reports are to be telephoned or faxed to the FDA and 
Genentech/Roche within 7 calendar days of first learning of the event. 
 
 
15 Calendar Day Written Report 
 
The Investigator is also required to notify the FDA and all participating investigators, in a 
written IND Safety Report, of any serious, unexpected AE that is considered reasonably or 
possibly related to the use of study drugs. An unexpected adverse event is one that is not 
already described in the study drugs investigator brochure. 
 
Written IND Safety reports should include an Analysis of Similar Events in accordance with 
regulation 21 CFR 
§ 312.32. All safety reports previously filed by the investigator with the IND concerning similar 
events should be analyzed and the significance of the new report in light of the previous, similar 
reports commented on. 
 
Written IND safety reports with Analysis of Similar Events are to be submitted to the FDA, 
Genentech/Roche, and all participating investigators within 15 calendar days of first learning of 
the event. The FDA prefers these reports on a MedWatch 3500 form, but alternative formats 
are acceptable (e.g., summary letter).

SAFETY CRISIS MANAGEMENT 
 
In case of a safety crisis, e.g., where safety issues have a potential impact on the 
indication(s), on the conduct of the Study, may lead to labeling changes or 
regulatory actions that limit or restrict the way in which the Product is used, or 
where there is media involvement, the Party where the crisis originates will contact 
the other Party as soon as possible. 
 
The Parties agree that Genentech/Roche shall have the final say and control over 
safety crisis management issues relating to the Product. City of Hope agrees that it 
shall not answer such queries from media and other sources relating to the 
Product but shall redirect such queries to Genentech/Roche. 
 
7. 
COH DATA AND SAFETY MONITORING 
Safety assessments will consist of monitoring and reporting adverse events and serious 
adverse events per protocol. This includes all events of death and any study-specific issue of 
concern. This is a Risk Level 4 study as defined in the City of Hope Institutional Data and 
Safety Monitoring Plan. This determination was made because the study involves a COH IND. 
 
Definition of Risk level 
Adverse Event (AE) 
An adverse event is any untoward medical experience or change of an existing condition that 
occurs during or after treatment, whether or not it is considered to be related to the protocol 
intervention. 
 
Serious Adverse Event (SAE) 
A serious adverse event is any expected or unexpected adverse events that result in any of the 
following outcomes: 
• 
Death 
• 
Is life-threatening experience (places the subject at immediate risk of death from the 
event as it occurred) 
• 
Unplanned hospitalization (equal to or greater than 24 hours) or prolongation of existing 
hospitalization 
• 
A persistent or significant disability/incapacity 
• 
A congenital anomaly/birth defect 
• 
Secondary malignancy* 
• 
Any other adverse event that, based upon appropriate medical judgment, may 
jeopardize the subject’s health and may require medical or surgical intervention to 
prevent one of the outcomes listed above (examples of such events include allergic 
bronchospasm requiring intensive treatment in the emergency room or at home, blood 
dyscrasias of convulsions that do not result in inpatient hospitalization, or the 
development of drug dependency or drug abuse).

Protocol 18496, Version 2.7 
109 
Unanticipated Problems Involving Risks to Subjects or Others 
An unanticipated problem is any incident, experience, or outcome that meets all three of the 
following criteria: 
1. Unexpected (in terms of nature, severity, or frequency) given the following: a) the research 
procedures described in the protocol-related documents such as the IRB approved 
research protocol, informed consent document or Investigator Brochure (IB); and b) the 
characteristics of the subject population being studied; AND 
2. Related or possibly related to participation in the research (possibly related means there is 
a reasonable possibility that the incident, experience, or outcomes may have been caused 
by the drugs, devices or procedures involved in the research); AND 
3. Suggests that the research places subjects or others at greater risk of harm (including 
physical, psychological, economic, or social harm) than previously known or recognized. 
 
 Adverse Events of Special Interest (AESI) 
See section 6 
 
Assessment of Adverse Events 
The site Investigator will be responsible for determining the event name, assessing the severity 
(i.e. grade), expectedness, and attribution of all adverse events.  
 
Assessment of Adverse Event Name and Grade 
Adverse events will be characterized using the descriptions and grading scales found in the 
most recent version of CTCAE 5.0.  The determination of severity for all other events not listed 
in CTCAE 5.0 the should be made by the investigator based on medical judgment and the 
severity categories of Grade 1 to 5 as defined below: 
• 
Grade 1 (mild) – An event that is usually transient and may require only minimal 
treatment or therapeutic intervention. The event does not generally interfere with usual 
activities of daily living. 
• 
Grade 2 (moderate) – An event that is usually alleviated with additional specific 
therapeutic intervention. The event interferes with usual activities of daily living, causing 
discomfort but poses no significant or permanent risk of harm to the subject. 
• 
Grade 3 (severe) – An event that requires intensive therapeutic intervention. The event 
interrupts usual activities of daily living, or significantly affects the clinical status of the 
subject. 
• 
Grade 4 (life threatening) – An event, and/or its immediate sequelae, that is associated 
with an imminent risk of death or with physical or mental disabilities that affect or limit the 
ability of the subject to perform activities of daily living (eating, ambulation, toileting, etc). 
• 
Grade 5 (fatal) – Death (loss of life) as a result of an event. 
 
Assessment of Attribution 
 
The following definitions will be used to determine the causality (attribution) of the event to the 
study agent or study procedure. 
• 
Unrelated – The event is clearly related to other factors such as the participant’s clinical 
state, other therapeutic interventions, or concomitant medications administered to the 
participant. 

Page 110 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
110 
• 
Unlikely – The event is doubtfully related to the investigational agent(s). The event was 
most likely related to other factors such as the participant’s clinical state, other 
therapeutic interventions, or concomitant drugs. 
• 
Possible – The event follows a reasonable temporal sequence from the time of drug 
administration, but could have been produced by other factors such as the participant’s 
clinical state, other therapeutic interventions, or concomitant drugs.  
• 
Probable – The event follows a reasonable temporal sequence from the time of drug 
administration, and follows a known response pattern to the study drug. The event 
cannot be reasonably explained by other factors such as the participant’s clinical state, 
therapeutic interventions, or concomitant drugs.  
• 
Definite – The event follows a reasonable temporal sequence from the time of drug 
administration, follows a known response pattern to the study drug, cannot be 
reasonably explained by other factors such as the participant’s condition, therapeutic 
interventions, or concomitant drugs, AND occurs immediately following study drug 
administration, improves upon stopping the drug, or reappears on re-exposure.  
 
Assessment of Expectedness 
The following definitions will be used to determine the expectedness of the event: 
• 
Unexpected – An adverse event is unexpected if it is not listed in the investigator’s 
brochure and/or package insert; is not listed at the specificity or severity that has been 
observed; is not consistent with the risk information described in the protocol and/or 
consent; is not an expected natural progression of any underlying disease, disorder, 
condition, or predisposed risk factor of the research participant experiencing the adverse 
event. *Modified from 21 CFR 312.32 (a) 
• 
Expected – An adverse event is expected if it does not meet the criteria for an 
unexpected event, OR is an expected natural progression of any underlying disease, 
disorder, condition, or predisposed risk factor of the research participant experiencing 
the adverse event.  
 
 
REPORTING OF ADVERSE EVENTS 
Routine Reporting of Non-Serious Adverse Events  
Routine AE recording will occur via data entry into the study eCRF. Recording of adverse 
events will begin once the patient is consented and will continue until 30 days post study. 
Adverse events will be monitored by the Protocol Management Team (PMT). Adverse events 
that do not meet the criteria of serious OR are not unanticipated problems do not require 
expedited reporting.  AEs reported through expedited processes (i.e. reported to the IRB, 
DSMC, FDA, etc.) must also be reported in routine study data submissions.  
 
EXPEDITING REPORTING REQUIREMENTS OF SAES AND UPS  
Adverse events that meet the criteria of serious OR are unanticipated problems will be reported 
according to the approved City of Hope’s Institutional policy via the AE/UP reporting form in 
iRIS. Reportable serious adverse events must be followed until the event is resolved, stabilized, 
or determined to be irreversible by the investigator.  Follow-up SAE reports must be submitted 
for all events that require expedited reporting when the status of the event changes and until the 
resolution or stabilization of the event.

Additional AE Reporting Requirements 
 
Reporting to the FDA  
The study PI (or designee) will be responsible for contacting the Office of IND Development and 
Regulatory Affairs (OIDRA) at COH to ensure prompt reporting of safety reports to the FDA.  
OIDRA will assist the PI with the preparation of the report and submit the report to the FDA in 
accordance with the approved City of Hope’s Institutional policy.  
 
Serious Adverse Events meeting the requirements for expedited reporting to the Food and Drug 
Administration (FDA), as defined in 21 CFR 312.32, will be reported as an IND safety report 
using the MedWatch Form FDA 3500A for Mandatory Reporting. 
 
The criteria that require reporting using the Medwatch 3500A are: 
• 
Any unexpected fatal or life threatening adverse experience associated with use of 
the drug must be reported to the FDA no later than 7 calendar days after initial 
receipt of the information [21 CFR 312.32(c)(2)] 
• 
Any adverse experience associated with use of the drug that is both serious and 
unexpected must be submitted no later than 15 calendar days after initial receipt of 
the information [21 CFR 312.32(c)(1)] 
• 
Any follow-up information to a study report shall be reported as soon as the relevant 
information becomes available. [21 CFR 312.32(d)(3)] 
 
In addition, the study PI will submit annually within 60 days (via COH OIDRA) of the anniversary 
date of when the IND went into effect, an annual report to the FDA which is to include a 
narrative summary and analysis of the information of all FDA reports within the reporting 
interval, a summary report of adverse drug experiences, and history of actions taken since the 
last report because of adverse drug experiences. 
 
Reporting to Genentech         
All serious adverse events and AESIs (initial and follow-up information) will be reported by the 
study PI to Genentech per Section 6. 
 
1. The following events will be reported using a MedWatch form in an expedited manner to 
Roche/Genentech Global Safety within 24 hours of being aware of the event (via OIDRA) 
(Table 13).  
2. SAE reports and any other relevant safety information will be forwarded to the 
Roche/Genentech Global Safety facsimile number 215 993-1220 (Attn: Worldwide

PROTOCOL DEVIATIONS AND SINGLE SUBJECT EXCEPTIONS 
It is understood that deviations from the protocol should be avoided, except when necessary to 
eliminate an immediate hazard to a research participant. Brief interruptions and delays may 
occasionally be required because of travel delays, airport closures, inclement weather, family 
responsibilities, security alerts, government holidays, and so forth. Delays can also extend to 
complications of disease or unrelated medical illnesses not related to disease progression. The 
PI has the discretion to deviate from the protocol when necessary so long as such a deviation 
does not threaten patient safety or protocol scientific integrity. As a result of deviations, 
corrective actions are to be developed by the study staff and implemented promptly. 
 
Definitions 
Deviation 
A deviation is a divergence from a specific element of a protocol that occurred without prior IRB 
approval.  Investigators may deviate from the protocol to eliminate immediate hazard(s) for the 
protection, safety, and well-being of the study subjects without prior IRB approval. Examples 
include, but are not limited to: a) dose adjustments based on excessive patient weight; b) 
alteration in treatment schedule due to non-availability of the research participant for treatment; 
and c) laboratory test results which are slightly outside the protocol requirements but at levels 
that do not affect participant safety. 
 
Single Subject Exceptions (SSE) 
An SSE is a planned deviation, meaning that it involves circumstances in which the specific 
procedures called for in a protocol are not in the best interests of a specific patient.  It is a 

Page 113 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
113 
deviation that is anticipated and receives prior approval by the Principal Investigator and the 
COH IRB. 
  
Reporting of Deviations and SSEs 
Reporting Deviations 
For any deviation, the Investigator will notify the COH DSMC and IRB within 5 calendar days of 
its occurrence via iRIS in accordance with the Clinical Research Protocol Deviation policy and 
Genentech requirement (Refer to Section 6 ) 
 
Reporting Single Subject Exceptions 
The SSE must be submitted as a “Single Subject Exception Amendment Request” via iRIS in 
accordance with IRB guidelines and the Clinical Research Protocol Deviation policy. An IRB 
approved SSE does not need to be submitted as a deviation to the DSMC.  
 
In addition, if contractually obligated, the sponsor must also approve the deviation.

CITY OF HOPE DATA AND SAFETY MONITORING COMMITTEE 
This is a risk level 4 study as defined in the City of Hope Institutional Data and Safety Monitoring 
Plan. This determination was made because the study involves phase I study and COH held 
IND. 
 
The DSMC is a multidisciplinary committee charged with overseeing the monitoring of safety of 
participants in clinical trials, and the conduct, progress, validity, and integrity of the data for all 
clinical trials that are sponsored by City of Hope. The committee is composed of clinical 
specialists with experience in oncology and who have no direct relationship with the study. The 
committee reviews the progress and safety of all active research protocols that are not 
monitored by another safety and data monitoring committee or board.  
 
The Study Principal Investigator is required to submit periodic status reports (the PMT report) 
according to the guidelines outlined in the City of Hope Institutional Data and Safety Monitoring 
Plan.  The PMT report will be submitted to the COH DSMC quarterly from the date of activation.   
 
The COH Data and Safety Monitoring Committee (DSMC) will review and monitor toxicity and 
accrual data from this trial. The DSMC will review up-to-date participant accrual; summary of all 
adverse events captured via routine and expedited reporting; a summary of deviations; any 
response information; monitoring reports, and summary comments provided by the study team. 
Other information (e.g. scans, laboratory values) will be provided upon request. For Phase I 
studies, a Phase I Tracking Log will be utilized and reviewed by the DSMC to monitor data and 
safety for dose escalation.  A review of outcome results (response, toxicity and adverse events) 
and factors external to the study (such as scientific or therapeutic developments) is discussed, 
and the Committee votes on the status of each study. Information that raises any questions 
about participant safety will be addressed with the Principal Investigator, statistician and study 
team.

Plasma  
1. For plasma preparation use 10 mL whole blood from green-top 
tubes. 
2. Centrifuge for 10 minutes at 1800 x g at 4 oC.  
3. The resulting upper plasma layer from each tube will be drawn up 
sequentially into a sterile 5 mL syringe and pushed through a sterile 
0.2/0.8 micron disposable filter.  
a. Save the plasma-depleted portion for isolation of PBMC (see 
below). 
4. The filtered plasma will then be transferred in 500 µL aliquots into 
multiple appropriately-labeled Starstedt microfuge tubes.  
5. To one aliquot, add 0.5 mL glycerol/0.02% sodium azide solution to 
dilute the plasma 50/50 v/v. Keep the diluted plasma sample at -20˚C 
and do not freeze.  
6. All the remaining plasma aliquots will be stored frozen at -80˚C until 
use. 
Peripheral 
blood 
mononuclear 
cells (PBMC) 
 
7. Any blood remaining in the two green-top tubes used to prepare 
plasma above will be diluted 1:1 with Hank’s Balanced Salt Solution 
(or equivalent) and combined with the whole blood from the unused 
green-top tube in a sterile 50 ml conical centrifuge tube. 
8. PBMC will then be isolated by Ficoll-gradient per COH APCF 
procedures. 
9. Isolated PBMC will be stored in 3 aliquoted tubes and stored at -80˚C 
until use.

8.3.3 Sample maintenance and distribution/shipping to laboratories 
A sample manifest will be maintained by the PI or designee. Samples will be maintained at APCF 
until distribution to internal collaborators/external vendors. Samples will be batch shipped to non-
COH vendors. 
Procedure for plasma/ buffy coat isolation from EDTA tubes: Collect blood in tube until 
filled. Mix tube by inverting 3-5 times and transport to lab for processing. Samples must be 
processed within one hour of collection to minimize the possibility of white blood cell lysis. For 
processing, centrifuge the samples at 820g for 10 min at room temperature and transfer 1 mL 
aliquots of the plasma to sterile 2 mL microtubes. Freeze plasma aliquots at -80 °C. Remove the 
Buffy coat layer into a separate pre-labeled tube and store at -800C. Record corresponding 
information such as collection time, freezing time, and aliquot number.  
 
Flow Cytometry and single cell RNA sequencing: Peripheral blood mononuclear cells 
(PBMCs) will be isolated from the blood of patients per manufacturer protocol. For flow 
cytometry, cells will be stained for immune subtype markers and sorted by fluorescence-
activated cell sorting (FACS) or CyTOF. For single cell sequencing, the cells will be loaded in 
Smarter ICELL8 single cell mRNA chip or the 10x, imaged via microscopy, and single cell 
libraries will be prepared per manufactures instructions. Next generation sequencing will be 
performed.  
8.4 STOOL SPECIMEN COLLECTION 
Fecal samples are relatively easy to collect and non-invasive. They provide an indication of the 
gut microbiome which may be an indicator of general health, impact drug availability, and 
indicate the presence of communities associated with inflammation, digestive inefficiencies, and 
pathogens. Monitoring the gut microbiome may allow us to predict the risk of possible side 
effects of ipatasertib and therapeutic efficacy.  
 
The exploratory objective to monitor the gut microbiota at baseline, on treatment and end of 
treatment using fecal samples.  The differences in gut microbiota within and between fecal 
samples will be compared using alpha and beta diversity metrics based on 16S rRNA 
sequencing.  
 
Stool sample will be collected in a Zymo® Research DNA/RNA Shield Fecal Collection Tube by 
patients as instructed. A standard operating procedure (SOP) has been generated for stool 
collection, as outlined in Appendix 7.  
 
Stool samples will be collected within 7 days prior to Cycle 1 Day 1, Cycle 4 Day 1 (+/- 7 days), 
and end of treatment (+/- 7 days). 
 
 
DIET and Bowel Movement Frequency Log  
 
A copy of this SOP will be provided to the patient and their understanding of the SOP will be 
documented by the study team (see Appendix 8).  
 
Samples will be collected pre-treatment (within 7 days of C1D1), C4 Day 1 (+/-7 days) and end 
of treatment EOT visit (+/-7 days) as described in study calendar. Patient will bring samples on 
the scheduled study visits.

STATISTICAL CONSIDERATIONS 
9.1 
DETERMINATION OF SAMPLE SIZE  
Phase I-dose escalation portion is the IQ 3+3 design, and the phase 1b-portion will be 
the expansion of each schedule to14 patients for Arms A, B, and at least 12 patients for 
Arm C. The expected combined sample size for this Phase I study and expanded cohort 
at the recommended phase 2 dose (RP2D) will be <=40 patients (with >99% probability, 
based on 800 simulations) for Arms A and B together, with an additional expected 24 
patients for Arm C (see below). For arms A and B the sample size will be 28 patients if 
level 1 has acceptable toxicity on both triplet schedule A and double schedule B.  
With 14 patients at the recommended Phase 2 dose for Arms A and B, the DLT rate can 
be estimated with a SE less than 13.5% and provides added information to refine the 
recommended phase 2 dose. In addition, with 14 patients, the likelihood of observing at 
least one patient with PI3K-mTOR-Akt- alteration/PTEN loss (per schedule) is 96% 
assuming an incidence in the population of 20%. Secondary analysis will also evaluate 
PFS and response based on molecular subtyping and PI3K-mTOR-Akt/PTEN loss and 
BRCA mutational status. For Arm C, with a minimum of 12 patients (maximum of 19), 
the DLT rate can be estimated with a SE less than 14.4%.  
At the end of the study, we will have at least 14 patients treated on RP2D for the triplet 
schedule A and the doublet schedule B, and at least 12 patients treated on the RP2D for 
the arm/schedule C.  Initially, the plan was to facilitate this comparison, when schedules 
A and B had available slots, by randomizing between schedule A and schedule B.  Due 
to limited time when both arms had slots, and due to prior treatment history which limited 
patients to one arm, this quasi-randomization proved impractical  and slot assignment 
will be determined based on open slots and treating physician preference.   This 
includes the new added schedule (Arm C).  As a result, comparison of response rates 
across the arms will be on descriptive as these represent different patient populations.   
 
 
9.2 
DETERMINATION OF SAMPLE SIZE FOR ARM C 
 
Sample-size for the triplet Arm C: The starting dose level for schedule C is not 
the highest possible dose to be tested, which differs from Arm A and B.  Once 
the MTD and recommended phase 2 dose (RP2D) is selected for Arm C, at least 
12 total patients will be treated at the RP2D.  The expected number of patients 
(based on 800 simulations with DLT rates of 9.0%, 10.8%, 13.6% and 18.0% or 
with DLT rates of 6.7%, 7.6%, 9.0% and 10.8% for levels 1-4) is between 17 and 
18 patients for dose-finding, and the interquartile range is 15-20 patients.  
 
This is based in the IQ3+3 design.  This method has been used in over 10 dose-
finding studies to reduce study duration by an average of approximately 23% for 
a typical Phase I study, with a median increase in the number of patients of 1-4, 

Page 124 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
124 
while reducing the number of patients turned away due to lack of slots. This 
method was first presented at JSM 2016, with the manuscript submitted (see 
below for additional details). 
 
The simulations assume 4 dose levels (-1,1,2,3), starting at dose level 1, with a 
course length of 28 days, uniform beta distribution for screening of 28 days, a 
screen failure probability of 30%, an inevaluable rate of 20%, and uniform beta 
distribution of time to inevaluable over the the 28 day course length, and DLT 
rates as noted above.  The time to DLT event is a beta(1.5,1) distribution over 
the course length, and the patient inter-arrival has a an exponential distribution 
with a mean of 10 days.  
 
 If after 12 patients have been accrued to the RP2D in total, the number of total 
patients remains less than 21, additional patients can be accrued to the RP2D 
(e.g. if the RP2D is dose level 1, with 6 patients treated, and 2 DLTs on dose 
level 2 for a total 8 patients, 13 additional patients can be added to dose level 1 
as opposed to only 6). With 12 patients, any specific severe toxicity with 20% 
incidence will be observed with 93% probability.  
 
Secondary Objectives: Clinical activity will be described based on the secondary 
objectives, with a description of the activity based on PD-L1 status.  Survival endpoints 
will be evaluated using Kaplan-Meier methods.  Other correlative studies are considered 
exploratory in the context of this limited Phase I study; however, when the sample size is 
12, a single group t-test with a 0.050 one-sided significance level will have 80% power to 
detect an effect size of 0.766.  
9.3 
PLANNED EFFICACY EVALUATIONS  
Planned efficacy evaluations will include assessment of response (RECIST) and 
evaluation of progression-free survival. The assessments are specified in the 
study calendar. 
Phase I Operating considerations and methods of analysis 
The Phase I design is the IQ 3+3. To evaluate the operating characteristics, we selected 
12 different scenarios, and ran 800 simulations. In all scenarios, the probability of 
selection of any dose as the MTD differed by less than 3% compared to the traditional 
3+3, with the majority within 1%. The mean number of DLTs above the MTD for the two 
designs (3+3 vs IQ 3+3) differed by 0.1 or less. The study duration was reduced by an 
average of 3.7 months for a standard scenario when implementing the queue-based 
variation of the 3+3 (the IQ 3+3).  
Tables will be created to summarize all toxicities and side effects by grade, attribution, 
dose, course (cycle 1 vs later cycles), organ and severity. Rates and associated 95% 
confidence limits will be estimated for DLTs at the RP2D, clinical benefit, response, and 
PIK3CA mutation rate. Kaplan Meier methods will be used to estimate the median and 

Page 125 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
125 
95% confidence limits for PFS, EFS, and OS. Descriptive statistics will be provided for 
the research participant demographics and pharmacokinetic parameters. Subgroup 
analysis based on correlative biomarkers per secondary endpoints will also be 
conducted.

11.6 SPECIAL AND VULNERABLE POPULATIONS  
11.6.1.1 Inclusion of Women and Minorities 
The study is open anyone regardless of gender or ethnicity. Efforts will be made to extend 
the accrual to a representative population, but in a trial which will accrue approximately 29 
participants, a balance must be struck between subject safety considerations and 
limitations on the number of individuals exposed to potentially toxic or ineffective 
treatments on the one hand and the need to explore gender, racial, and ethnic aspects of 
clinical research on the other. If differences in outcome that correlate to gender, racial, or 
ethnic identity are noted, accrual may be expanded or additional studies may be 
performed to investigate those differences more fully. 
Pregnant women are excluded because the study drugs may have adverse effects on a 
fetus in uterus. 
11.6.1.2 Exclusion of Children 
Children (< 18 years old of age) are excluded from this study because the disease does 
not primarily affect children.  
11.6.1.3 Inclusion of HIV Positive Individuals 
Participants with a history of HIV are excluded from receiving protocol therapy due to 
concerns about inadvertent augmentation of infectious and/or inflammatory activity. 
11.6.1.4 Vulnerable Populations 
45 CFR §46.111 (a)(3) and 45 CFR §46, Subparts B-D identifies children, prisoners, 
pregnant women, mentally incapacitated persons, or economically or educationally 
disadvantaged persons as vulnerable populations.  
Adults lacking capacity to consent are not excluded from participation. This study does not 
pose additional risks for adults lacking capacity than for the general population. In such 
instances, informed consent will be sought and documented from the prospective 
participant’s legally authorized representative in agreement with institutional policies and 
COH IRB approval. 
11.7 PARTICIPANT CONFIDENTIALITY  
Participant confidentiality is strictly held in trust by the investigators, study staff, and the 
sponsor(s) and their agents. This confidentiality is extended to cover testing of biological 
samples in addition to any study information relating to participants. 
This research will be conducted in compliance with federal and state requirements relating 
to protected health information (PHI), including the requirements of the Health Insurance 
Portability and Accountability Act of 1996 (HIPAA). HIPAA regulations require a signed 
participant authorization informing the participant of the nature of the PHI to be collected, 
who will have access to that information and why, who will use or disclose that information, 

Page 129 of 172 
 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
129 
ant the rights of a research participant to revoke their authorization for use of their PHI. In 
the event that a participant revokes authorization to collect or use PHI, the investigator, 
by regulation, retains the ability to use all information collected prior to the revocation of 
participant authorization. For participants that have revoked authorization to collect or use 
PHI, attempts should be made to obtain permission to collect at least vital status (i.e. that 
the participant is alive) at the end of their scheduled study period. 
Release of research results should preserve the privacy of medical information and must 
be carried out in accordance with Department of Health and Human Services Standards 
for Privacy of Individually Identifiable Health Information, 45 CFR 164.508. When results 
of this study are reported in medical journals or at meetings, identification of those taking 
part will not be disclosed and no identifiers will be used. 
Medical records of participants will be securely maintained in the strictest confidence, 
according to current legal requirements. Data will be entered, analyzed and stored in 
encrypted, password protected, secure computers that meet all HIPAA requirements. All 
data capture records, drug accountability records, study reports and communications will 
identify the patient by initials and the assigned patient number. 
The investigator/institution will permit direct access to source data and documents by 
sponsor representatives, the FDA, and other applicable regulatory authorities. The access 
may consist of trial-related monitoring/ auditing, IRB reviews, and FDA/regulatory authority 
inspections. The participant’s confidentiality will be maintained and will not be made 
publicly available to the extent permitted by the applicable laws and regulations. 
11.8 FUTURE USE OF SPECIMENS COLLECTED FOR THIS TRIAL  
Left-over specimens will be stored for up to 10 years. 
11.9 CONFLICT OF INTEREST 
Any investigator who has a conflict of interest with this study (patent ownership, royalties, 
or financial gain greater than the minimum allowable by their institution, etc.) must have 
the conflict reviewed by a properly constituted Conflict of Interest Committee with a 
Committee-sanctioned conflict management plan that has been reviewed and approved 
by the study Sponsor (City of Hope) prior to participation in this study. All City of Hope 
investigators will follow the City of Hope conflict of interest policy.

Notes:* On treatment days, all assessments should be performed prior to dosing, unless otherwise specified. Patient will have MD 
visits on Days 1, 15 of cycle 1 & 2, then day 1 of each following cycles. Additional study nurse visit on Day8 of C1 & 2 for 
AE assessment. 
a Results of standard-of-care tests or examinations performed prior to obtaining informed consent and within 28 days prior to Day 1 
may be used; such tests do not need to be repeated for screening. Staging CT/PET-CT/bone scan/MRI brain can be used if 
performed within 35 days prior to Day1Cycle1.  
b End of treatment visit (EOT): Patients who discontinue study treatment will return to the clinic for a treatment discontinuation visit 
not more than 30 days after the last dose of study treatment. The visit at which response assessment shows progressive disease 
may be used as the treatment discontinuation visit. 
c Informed consent must be documented before any study-specific screening procedure is performed, and may be obtained more 
than 28 days before initiation of study treatment. 
d EORTC QLQ-C30 questionnaire will be completed on C1D1, then every 3 cycle at the tumor assessment visit, before the 
patient receives any information on disease status and prior to the performance of non-PRO assessments and the administration 
of study treatment. Study personnel should review all questionnaires for completeness before the patient leaves the 
investigational site. Patients who discontinue study treatment for any reason other than progressive disease or loss of clinical 
benefit will complete the EORTC QLQ-C30 at each tumor assessment visit, until radiographic disease progression per RECIST 
v1.1 or loss of clinical benefit determined by treating physician or study investigator. All patients will complete the EORTC QLQ-
C30 at 3 and 6 months after radiographic disease progression per RECIST v1.1 or (for ipatasertib-treated patients who continue 
treatment after radiographic disease progression) loss of clinical benefit as determined by the investigator.

e ECG recordings will be obtained during screening and as clinically indicated at other timepoints. For safety monitoring purposes, 
the investigator must review, sign, and date all ECG tracings. 
f Screening laboratory test results must be obtained within 14 days prior to initiation of study treatment. If screening laboratory 
assessments were performed within 96 hours prior to Day 1 of Cycle 1, they do not have to be repeated. CBC, diff and CMP will 
be drawn on days 1,8,15 of each cycle. 
g Amylase, lipase, and thyroid function test should be checked every other cycle. 
h All women of childbearing potential will have a serum pregnancy test within 96 hours prior to initiation of study drug, HCG does 
not need to be repeated thereafter.  
i At screening, patients will be tested for HBsAg, HBsAb, total HBcAb, and HCV antibody, as well as HIV serology. If a patient has 
a negative HBsAg test and a positive total HBcAb test at screening, an HBV DNA test should be performed. If a patient has a 
positive HCV antibody test at screening, an HCV RNA test must also be performed to determine if the patient has an active HCV 
infection. 
j Fasting lipid profile and HbA1c will be assessed at screening, every 3 cycles starting on Day 1 of Cycle 4, and at end-of-study 
visit. 
k Peripheral blood samples will be collection for biomarker correlatives will be collected at C1D1, C2D1, C4D1 and end-of-
treatment visit: 1 green top, 1 Streck tube (Cell-free DNA BCT®) and 1 lavender top. 
l Stool samples will be collected at: baseline (within 7 dyas), C4D1(+/- 3 days) and end-of-treatment visit.  
m If archival tissue is unavailable or is determined to be unsuitable for required testing, a pretreatment tumor biopsy is required. A 
pretreatment tumor biopsy may also be performed if a patient's archival tissue test results do not meet eligibility criteria. Refer to 
Section 4.5. for tissue sample requirements. Patients will undergo tumor biopsy sample collection, if deemed clinically feasible 
by the investigator, at the time of first evidence of radiographic disease progression per RECIST v1.1. Biopsies should be 
performed within 40 days after progression or prior to the next anti-cancer therapy, whichever is sooner. See Section 4.5. for 
tissue sample requirements.  
n All measurable and evaluable lesions should be assessed and documented at screening. Tumor assessments performed as 
standard of care prior to obtaining informed consent and within 35 days prior to initiation of study treatment do not have to be 
repeated at screening. Screening assessments must include CT scans (with oral or IV contrast), bone scan and MRI Brain 
(or CT of brain with contrast if MRI is contraindicated). If a CT scan with contrast is contraindicated (i.e., in patients with 
contrast allergy or impaired renal clearance), a non-contrast CT scan of the chest may be performed and MRI scans of the 
abdomen, pelvis, and head should be performed. An MRI scan of the head is required to confirm or refute the diagnosis of CNS 
metastases at baseline in the event of an equivocal CT scan. On study bone scans and CT scans of the neck should also be 
performed if clinically indicated. At the investigator’s discretion, other methods of assessment of measurable disease as per 
RECIST v1.1 may be used. Restaging scans are repeated every 3 months or 12 weeks.

o Patients will undergo tumor assessments at baseline, every 12 weeks or 3 cycles until radiographic disease progression per 
RECIST v1.1 OR loss of clinical benefit as determined by the investigator. Thus, tumor assessments are to continue according to 
schedule in patients who discontinue treatment for reasons other than disease progression or loss of clinical benefit. 
      All measurable and evaluable lesions should be re-assessed at each subsequent tumor evaluation. The same radiographic 
procedures used to assess disease sites at screening should be used for subsequent tumor assessments (e.g., the same 
contrast protocol for CT scans). 
P Medication (e.g., prescription drugs, over-the-counter drugs, vaccines, herbal or homeopathic remedies, nutritional supplements) 
used by a patient in addition to protocol-mandated treatment from 14 days prior to initiation of study treatment until the treatment 
discontinuation visit. 
q 
After informed consent has been obtained but prior to initiation of study treatment, only serious adverse events caused by a 
protocol-mandated intervention should be reported. After initiation of study treatment, all adverse events will be reported until 30 
days after the last dose of study treatment or until initiation of new systemic anti-cancer therapy, whichever occurs first, and 
serious adverse events and adverse events of special interest will continue to be reported until 90 days after the last dose of 
study treatment or until initiation of new systemic anti-cancer therapy, whichever occurs first. After this period, all deaths, 
regardless of cause, should be reported. In addition, Genentech, Inc. should be notified if the investigator becomes aware of any 
serious adverse event that is believed to be related to prior exposure to study treatment (see Appendix 3). The investigator 
should follow each adverse event until the event has resolved to baseline grade or better, the event is assessed as stable by the 
investigator, the patient is lost to follow-up, or the patient withdraws consent. Every effort should be made to follow all serious 
adverse events considered to be related to study treatment or trial-related procedures until a final outcome can be reported. 
r 
The initial dose of ipatasertib will be given with the witness of study team. Carboplatin and paclitaxel infusion will be delivered per 
current FDA package insert. If an infusion reaction occurs, subsequent infusion can be given with extended infusion time per 
institutional practice and guidance from pharmacy. For dosing regimen, see Section 3.1. Ipatasertib will be given at a starting 
dose of 400mg oral daily for 28 days. Carboplatin will be given at a starting dose of AUC2 on days 1, 8, 15 every 28 days for 
Triplet Schedule A. Paclitaxel will be given at a dose of 80 mg/m2 administered by IV infusion on days 1,8,15 of every 28 day 
cycles for Triplet Schedule A. Carboplatin will be given at a starting dose of AUC 2 on days 1, 8, 15 of 28 day cycles for doublet 
schedule B. 
s 
After treatment discontinuation, information on survival follow-up and new anti-cancer therapy (including targeted therapy and 
immunotherapy) will be collected via telephone calls, patient medical records, and/or clinic visits approximately every 3 months 
(unless the patient withdraws consent or the Investigator terminates the study). If a patient requests to be withdrawn from follow-
up, this request must be documented in the source documents and signed by the investigator. If the patient withdraws from study, 
the study staff may use a public information source (e.g., county records) to obtain information about survival status only. 
r    Patient diary will be distributed to patients on day 1 each cycle, need to be filled by patient and returned to study team on day 1 
of each following cycle and each MD/study nurse visit.

Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 
Selected sections from the Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST 
v1.1), (Eisenhauer et al. 2009) are presented below, with slight modifications from the original 
publication and the addition of explanatory text as needed for clarity.1 
TUMOR MEASURABILITY 
At baseline, tumor lesions/lymph nodes will be categorized as measurable or non-measurable 
as described below. All measurable and non-measurable lesions should be assessed at 
screening and at subsequent protocol-specified tumor assessment timepoints. Additional 
assessments may be performed as clinically indicated for suspicion of progression. 
DEFINITION OF MEASURABLE LESIONS 
Tumor Lesions 
Tumor lesions must be accurately measured in at least one dimension (longest diameter in the 
plane of measurement is to be recorded) with a minimum size as follows:  
• 
10 mm by computed tomography (CT) or magnetic resonance imaging (MRI) scan (CT/MRI 
scan slice thickness/interval ≤ 5 mm) 
• 
10-mm caliper measurement by clinical examination (lesions that cannot be accurately 
measured with calipers should be recorded as non-measurable) 
• 
20 mm by chest X-ray 
 
Malignant Lymph Nodes 
To be considered pathologically enlarged and measurable, a lymph node must be ≥ 15 mm in 
the short axis when assessed by CT scan (CT scan slice thickness recommended to be ≤ 5 
mm). At baseline and follow-up, only the short axis will be measured and followed. Additional 
information on lymph node measurement is provided below (see "Identification of Target and 
Non-Target Lesions" and "Calculation of Sum of Diameters"). 
 
1 For clarity and for consistency within this document, the section numbers and cross-
references to other sections within the article have been deleted and minor changes 
have been made. 

 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
155 
DEFINITION OF NON-MEASURABLE LESIONS 
Non-measurable tumor lesions encompass small lesions (longest diameter < 10 mm or 
pathological lymph nodes with short axis ≥ 10 mm but < 15 mm) as well as truly non-measurable 
lesions. Lesions considered truly non-measurable include leptomeningeal disease, ascites, 
pleural or pericardial effusion, inflammatory breast disease, lymphangitic involvement of skin or 
lung, peritoneal spread, and abdominal mass/abdominal organomegaly identified by physical 
examination that is not measurable by reproducible imaging techniques. 
SPECIAL CONSIDERATIONS REGARDING LESION MEASURABILITY 
Bone lesions, cystic lesions, and lesions previously treated with local therapy require particular 
comment, as outlined below. 
Bone Lesions: 
• 
Technetium-99m bone scans, sodium fluoride positron emission tomography scans, and 
plain films are not considered adequate imaging techniques for measuring bone lesions. 
However, these techniques can be used to confirm the presence or disappearance of bone 
lesions. 
• 
Lytic bone lesions or mixed lytic-blastic lesions with identifiable soft tissue components that 
can be evaluated by cross-sectional imaging techniques such as CT or MRI can be 
considered measurable lesions if the soft tissue component meets the definition of 
measurability described above. 
• 
Blastic bone lesions are non-measurable. 
 
Cystic Lesions: 
• 
Lesions that meet the criteria for radiographically defined simple cysts should not be 
considered malignant lesions (neither measurable nor non-measurable) since they are, by 
definition, simple cysts. 
• 
Cystic lesions thought to represent cystic metastases can be considered measurable 
lesions if they meet the definition of measurability described above. However, if non-cystic 
lesions are present in the same patient, these are preferred for selection as target lesions. 
 
Lesions with Prior Local Treatment: 
• 
Tumor lesions situated in a previously irradiated area or in an area subjected to other loco-
regional therapy are usually not considered measurable unless there has been 
demonstrated progression in the lesion.  
 
METHODS FOR ASSESSING LESIONS 
All measurements should be recorded in metric notation, using calipers if clinically assessed. All 
baseline evaluations should be performed as close as possible to the treatment start and never 
more than 4 weeks before the beginning of the treatment. 

 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
156 
The same method of assessment and the same technique should be used to characterize each 
identified and reported lesion at baseline and during the study. Imaging-based evaluation should 
always be the preferred option. 
CLINICAL LESIONS 
Clinical lesions will only be considered measurable when they are superficial and ≥ 10 mm in 
diameter as assessed using calipers (e.g., skin nodules). For the case of skin lesions, 
documentation by color photography, including a ruler to estimate the size of the lesion, is 
suggested. 
CHEST X-RAY 
Chest CT is preferred over chest X-ray, particularly when progression is an important endpoint, 
since CT is more sensitive than X-ray, particularly in identifying new lesions. However, lesions 
on chest X-ray may be considered measurable if they are clearly defined and surrounded by 
aerated lung. 
CT AND MRI SCANS 
CT is the best currently available and reproducible method to measure lesions selected for 
response assessment. In this guideline, the definition of measurability of lesions on CT scan is 
based on the assumption that CT slice thickness is ≤ 5 mm. When CT scans have slice 
thickness of > 5 mm, the minimum size for a measurable lesion should be twice the slice 
thickness. MRI is also acceptable.  
If prior to enrollment it is known that a patient is unable to undergo CT scans with intravenous 
(IV) contrast because of allergy or renal insufficiency, the decision as to whether a non-contrast 
CT or MRI (without IV contrast) will be used to evaluate the patient at baseline and during the 
study should be guided by the tumor type under investigation and the anatomic location of the 
disease. For patients who develop contraindications to contrast after baseline contrast CT is 
done, the decision as to whether non-contrast CT or MRI (enhanced or non-enhanced) will be 
performed should also be based on the tumor type and the anatomic location of the disease, 
and should be optimized to allow for comparison with the prior studies if possible. Each case 
should be discussed with the radiologist to determine if substitution of these other approaches is 
possible and, if not, the patient should be considered not evaluable from that point forward. 
Care must be taken in measurement of target lesions and interpretation of non-target disease or 
new lesions on a different modality, since the same lesion may appear to have a different size 
using a new modality. 
ENDOSCOPY, LAPAROSCOPY, ULTRASOUND, TUMOR MARKERS, CYTOLOGY, 
HISTOLOGY 
Endoscopy, laparoscopy, ultrasound, tumor markers, cytology, and histology cannot be utilized 
for objective tumor evaluation.

Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
157 
ASSESSMENT OF TUMOR BURDEN 
To assess objective response or future progression, it is necessary to estimate the overall tumor 
burden at baseline and use this as a comparator for subsequent measurements. 
IDENTIFICATION OF TARGET AND NON-TARGET LESIONS 
When more than one measurable lesion is present at baseline, all lesions up to a maximum of 
five lesions total (and a maximum of two lesions per organ) representative of all involved organs 
should be identified as target lesions and will be recorded and measured at baseline. This 
means that, for instances in which patients have only one or two organ sites involved, a 
maximum of two lesions (one site) and four lesions (two sites), respectively, will be recorded. 
Other lesions (albeit measurable) in those organs will be considered non-target lesions.  
Target lesions should be selected on the basis of their size (lesions with the longest diameter) 
and be representative of all involved organs, but in addition should lend themselves to 
reproducible repeated measurements. It may be the case that, on occasion, the largest lesion 
does not lend itself to reproducible measurement, in which circumstance the next largest lesion 
that can be measured reproducibly should be selected. 
Lymph nodes merit special mention since they are normal anatomical structures that may be 
visible by imaging even if not involved by tumor. As noted above, pathological nodes that are 
defined as measurable and may be identified as target lesions must meet the criterion of a short 
axis of ≥ 15 mm by CT scan. Only the short axis of these nodes will contribute to the baseline 
sum. The short axis of the node is the diameter normally used by radiologists to judge if a node 
is involved by solid tumor. Lymph node size is normally reported as two dimensions in the plane 
in which the image is obtained (for CT, this is almost always the axial plane; for MRI, the plane 
of acquisition may be axial, sagittal, or coronal). The smaller of these measures is the short 
axis. For example, an abdominal node that is reported as being 20 mm × 30 mm has a short axis 
of 20 mm and qualifies as a malignant, measurable node. In this example, 20 mm should be 
recorded as the node measurement. All other pathological nodes (those with short axis ≥ 10 mm 
but < 15 mm) should be considered non-target lesions. Nodes that have a short axis of < 10 mm 
are considered non-pathological and should not be recorded or followed. 
All lesions (or sites of disease) not selected as target lesions (measurable or non-measurable), 
including pathological lymph nodes, should be identified as non-target lesions and should also 
be recorded at baseline. Measurements are not required. It is possible to record multiple 
non-target lesions involving the same organ as a single item on the Case Report Form (CRF) 
(e.g., "multiple enlarged pelvic lymph nodes" or "multiple liver metastases"). 
CALCULATION OF SUM OF DIAMETERS 
A sum of the diameters (longest diameter for non−lymph node lesions, short axis for lymph node 
lesions) will be calculated for all target lesions at baseline and at each subsequent tumor 
assessment as a measure of tumor burden.

Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
158 
Measuring Lymph Nodes 
Lymph nodes identified as target lesions should always have the actual short axis measurement 
recorded (measured in the same anatomical plane as the baseline examination), even if the 
node regresses to < 10 mm during the study. Thus, when lymph nodes are included as target 
lesions, the sum of diameters may not be zero even if complete response criteria are met, since 
a normal lymph node is defined as having a short axis of < 10 mm. 
Measuring Lesions That Become Too Small to Measure 
During the study, all target lesions (lymph node and non−lymph node) recorded at baseline 
should have their actual measurements recorded at each subsequent evaluation, even when 
very small (e.g., 2 mm). However, sometimes lesions or lymph nodes that are recorded as 
target lesions at baseline become so faint on CT scan that the radiologist may not feel 
comfortable assigning an exact measurement and may report them as being too small to 
measure. When this occurs, it is important that a value be recorded on the CRF, as follows: 
• 
If it is the opinion of the radiologist that the lesion has likely disappeared, the measurement 
should be recorded as 0 mm. 
• 
If the lesion is believed to be present and is faintly seen but too small to measure, a default 
value of 5 mm should be assigned and "too small to measure" should be ticked. (Note: It is 
less likely that this rule will be used for lymph nodes since they usually have a definable 
size when normal and are frequently surrounded by fat such as in the retroperitoneum; 
however, if a lymph node is believed to be present and is faintly seen but too small to 
measure, a default value of 5 mm should be assigned in this circumstance as well and "too 
small to measure" should also be ticked). 
 
To reiterate, however, if the radiologist is able to provide an actual measurement, that should be 
recorded, even if it is < 5 mm, and in that case "too small to measure" should not be ticked. 
Measuring Lesions That Split or Coalesce on Treatment 
When non−lymph node lesions fragment, the longest diameters of the fragmented portions 
should be added together to calculate the sum of diameters. Similarly, as lesions coalesce, a 
plane between them may be maintained that would aid in obtaining maximal diameter 
measurements of each individual lesion. If the lesions have truly coalesced such that they are 
no longer separable, the vector of the longest diameter in this instance should be the maximum 
longest diameter for the coalesced lesion. 
EVALUATION OF NON-TARGET LESIONS 
Measurements are not required for non-target lesions, except that malignant lymph node non-
target lesions should be monitored for reduction to < 10 mm in short axis. Non-target lesions 
should be noted at baseline and should be identified as "present" or "absent" and (in rare cases) 
may be noted as "indicative of progression" at subsequent evaluations. In addition, if a lymph 
node lesion shrinks to a non-malignant size (short axis < 10 mm), this should be captured on the 
CRF as part of the assessment of non-target lesions.

RESPONSE CRITERIA 
CRITERIA FOR TARGET LESIONS 
Definitions of the criteria used to determine objective tumor response for target lesions are 
provided below: 
• 
Complete response (CR): Disappearance of all target lesions 
Any pathological lymph nodes must have reduction in short axis to < 10 mm. 
• 
Partial response (PR): At least a 30% decrease in the sum of diameters of all target lesions, 
taking as reference the baseline sum of diameters, in the absence of CR 
• 
Progressive disease (PD): At least a 20% increase in the sum of diameters of target 
lesions, taking as reference the smallest sum of diameters on study (including baseline)  
In addition to the relative increase of 20%, the sum of diameters must also 
demonstrate an absolute increase of ≥ 5 mm. 
• 
Stable disease (SD): Neither sufficient shrinkage to qualify for CR or PR nor sufficient 
increase to qualify for PD 
 
CRITERIA FOR NON-TARGET LESIONS 
Definitions of the criteria used to determine the tumor response for the group of non-target 
lesions are provided below. While some non-target lesions may actually be measurable, they 
need not be measured and instead should be assessed only qualitatively at the timepoints 
specified in the schedule of activities. 
• 
CR: Disappearance of all non-target lesions and (if applicable) normalization of tumor 
marker level 
All lymph nodes must be non-pathological in size (< 10 mm short axis). 
• 
Non-CR/Non-PD: Persistence of one or more non-target lesions and/or (if applicable) 
maintenance of tumor marker level above the normal limits 
• 
PD: Unequivocal progression of existing non-target lesions 
 
SPECIAL NOTES ON ASSESSMENT OF PROGRESSION OF NON-TARGET 
LESIONS 
Patients with Measurable and Non-Measurable Disease 
For patients with both measurable and non-measurable disease to achieve unequivocal 
progression on the basis of the non-target lesions, there must be an overall level of substantial 
worsening in non-target lesions in a magnitude that, even in the presence of SD or PR in target 
lesions, the overall tumor burden has increased sufficiently to merit discontinuation of therapy. A 
modest increase in the size of one or more non-target lesions is usually not sufficient to qualify 
for unequivocal progression status. The designation of overall progression solely on the basis of 
change in non-target lesions in the face of SD or PR in target lesions will therefore be extremely 
rare. 

 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
160 
Patients with Non-Measurable Disease Only  
For patients with non-measurable disease only, the same general concepts apply as noted 
above. However, in this instance there is no measurable disease assessment to factor into the 
interpretation of an increase in non-measurable disease burden. Because worsening in non-
measurable disease cannot be easily quantified (by definition, if all lesions are truly non-
measurable), a useful test that can be applied when assessing patients for unequivocal 
progression is to consider if the increase in overall disease burden based on the change in non-
measurable disease is comparable in magnitude to the increase that would be required to 
declare PD for measurable disease, that is, an increase in tumor burden representing an 
additional 73% increase in volume (which is equivalent to a 20% increase in diameter in a 
measurable lesion). Examples include an increase in a pleural effusion from "trace" to "large" or 
an increase in lymphangitic disease from localized to widespread If unequivocal progression is 
seen, the patient should be considered to have had overall PD at that point. While it would be 
ideal to have objective criteria to apply to non-measurable disease, the very nature of that 
disease makes it impossible to do so; therefore, the increase must be substantial. 
NEW LESIONS 
The appearance of new malignant lesions denotes disease progression; therefore, some 
comments on detection of new lesions are important. There are no specific criteria for the 
identification of new radiographic lesions; however, the finding of a new lesion should be 
unequivocal, that is, not attributable to differences in scanning technique, change in imaging 
modality, or findings thought to represent something other than tumor (for example, some "new" 
bone lesions may be simply healing or flare of preexisting lesions). This is particularly important 
when the patient’s baseline lesions show PR or CR. For example, necrosis of a liver lesion may 
be reported on a CT scan report as a "new" cystic lesion, which it is not. 
A lesion identified during the study in an anatomical location that was not scanned at baseline is 
considered a new lesion and will indicate disease progression. 
If a new lesion is equivocal, for example because of its small size, continued therapy and follow-
up evaluation will clarify if it represents truly new disease. If repeat scans confirm there is 
definitely a new lesion, progression should be declared using the date of the initial scan. 
CRITERIA FOR OVERALL RESPONSE AT A SINGLE TIMEPOINT 
Appendix 6 Table 1 provides a summary of the overall response status calculation at each 
response assessment timepoint for patients who have measurable disease at baseline. 
When patients have non-measurable (therefore non-target) disease only, Appendix 6 
Table 2 is to be used.

a "Non-CR/non-PD" is preferred over "stable disease" for non-target disease since 
stable disease is increasingly used as an endpoint for assessment of efficacy in 
some trials; thus, assigning "stable disease" when no lesions can be measured is 
not advised. 
 
MISSING ASSESSMENTS AND NOT-EVALUABLE DESIGNATION 
When no imaging/measurement is done at all at a particular timepoint, the patient is not 
evaluable at that timepoint. If measurements are made on only a subset of target lesions at a 
timepoint, usually the case is also considered not evaluable at that timepoint, unless a 
convincing argument can be made that the contribution of the individual missing lesions would 
not change the assigned timepoint response. This would be most likely to happen in the case of 
PD. For example, if a patient had a baseline sum of 50 mm with three measured lesions and 

 
. 
Ipatasertib  City of Hope 
Protocol 18496, Version 2.7 
162 
during the study only two lesions were assessed, but those gave a sum of 80 mm, the patient 
will have achieved PD status, regardless of the contribution of the missing lesion.  
SPECIAL NOTES ON RESPONSE ASSESSMENT 
Patients with a global deterioration in health status requiring discontinuation of treatment without 
objective evidence of disease progression at that time should be reported as "symptomatic 
deterioration." Every effort should be made to document objective progression even after 
discontinuation of treatment. Symptomatic deterioration is not a descriptor of an objective 
response; it is a reason for stopping study therapy. The objective response status of such 
patients is to be determined by evaluation of target and non-target lesions as shown in 
Appendix 6 Table 1 and Appendix 6 Table 2. 
For equivocal findings of progression (e.g., very small and uncertain new lesions; cystic 
changes or necrosis in existing lesions), treatment may continue until the next scheduled 
assessment. If at the next scheduled assessment, progression is confirmed, the date of 
progression should be the earlier date when progression was suspected.

Stool Collection Kit General Instructions 
As a part of your participation in the current study, we have some specific instructions related to 
collection of stool. Please abide by these instructions, as they are essential for the proper 
conduct of the study. 
 
You are being asked to collect samples at the following times: Day-7 to Day -1 of Cycle 1 Day 1; 
Cycle 4 Day 1 (+/- 7 days); End of treatment (+/-7 days) 
Before you begin, review the following: 
a. Make sure you have a collection hat and collection tube. 
b. Make sure you are able to deliver the sample to City of Hope within 1 week. 
 
STEP 1: Please place the collection hat around the 
rim of your toilet seat for stool collection.  
 
STEP 2: Unscrew the collection tube cap and use the 
spoon to scoop one spoonful of feces (about the size 
of a quarter) from a sample.  
 
Place the sample in the collection tube.  
 
Tighten the cap and shake to mix the contents 
thoroughly (invert 10 times) to create a suspension.  
 
Note: Some fecal material may be difficult to re-
suspend. As long as the material is suspended, the 
sample is stabilized. Foaming/frothing during shaking 
is normal.  
 
STEP 3: Wash hands well, and write today’s date on 
the label.
