Final Protocol v5.0: July 28, 2022 
Exploratory 
• To study the correlation of clinical outcomes with Next Generation 
Sequencing and Immunohistochemical analyses of tumor 
biomarkers, including baseline secreted protein acidic and rich in 
cysteine (SPARC) expression. 
• To assess baseline tumoral immune parameters, including PD-1, 
PD-L1, mutational burden, and infiltrating lymphocytes, in 
correlation with clinical outcomes. 
STUDY 
ENDPOINTS 
Endpoints in Phase 1 
Primary Endpoint  
• Dose-limiting-toxicities (DLTs), used to estimate the maximum-
tolerated dose (MTD) of nab-Sirolimus in combination with 
pazopanib, where the MTD is defined as the highest dose where 
≤1 of 6 (or 0 of 3) subjects experience a DLT, thus a target DLT rate 
of roughly 17%. 
Secondary Endpoint 
• Adverse Events profile (based on National Cancer Institute [NCI] 
Common Terminology Criteria for Adverse Events [CTCAE] v5.0) of 
all subjects and each dose cohort 
Endpoints in Phase 2 – data both from Phase 1 and 2  
Primary Endpoint  
• Progression-free survival (PFS) rate at 3 months, based on 
Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 
Secondary Endpoint 
• Adverse Events profile (based on NCI CTCAE v5.0) 
• Median PFS, PFS rate at 6 months, based on RECIST v1.1 
• Median overall survival (OS), OS at 12 months 
• Objective response rate (ORR) based on Response Evaluation 
Criteria in Solid Tumors (RECIST) v1.1 
• Disease control rate (DCR), defined as complete response (CR) 
plus partial response (PR) plus stable disease (SD) ≥18 weeks, 
based on RECIST v1.1 
• Duration of response

Final Protocol v5.0: July 28, 2022 
• Optional pre-treatment tumor tissue collection (fresh or archival) 
for biomarker analysis: 
1. Correlation of genetic profiling and tissue biomarker 
analysis with clinical benefit 
2. Correlation of baseline secreted protein acidic and rich in 
cysteine (SPARC) expression with clinical benefit 
3. Correlation of baseline immune parameters with clinical 
benefit 
STUDY DESIGN 
This is an open label, dose-finding, single-arm, prospective phase 1/2 
study to identify the RP2D of nab-Sirolimus given IV on either Day 1 and 
Day 8 (qw2/3), or Day 1 only of a 21-day cycle (qw1/3), plus daily oral 
pazopanib in subjects with advanced nonadipocytic STS.  
The study will be conducted in compliance with International Conference 
on Harmonization (ICH) Good Clinical Practices (GCPs). 
Dose-finding Phase 1 Portion of the Study:   
Dose levels of nab-Sirolimus will be tested in cohorts of 3 subjects each 
using the 3+3 dose-finding design. A summary of dose levels and cohorts 
are provided in Table 1 and Table 2. 
Phase 2 Portion of the Study:  
This will be conducted using Simon’s two-stage design. Subjects enrolled 
in the phase 1 study at the RP2D cohort will be included for response and 
safety evaluation in phase 2. 
STUDY DRUG 
ADMINISTRATION 
Subjects will receive nab-Sirolimus by IV infusion over a minimum of 30 
(+10) minutes at 100, 75, 60, 45, 30, 20, or 15 mg/m2 either Days 1 and 8 
in a 21-day cycle  or on Day 1 only in a 21-day cycle. 
Pazopanib will be given per standard of care guidelines, daily. Pazopanib 
dosing may be initiated at 400, or 800 mg once daily by mouth, without 
food (at least 1 hour before or 2 hours after a meal). Pazopanib starting 
dose must remain consistent within a dose-finding cohort. 
Subjects will continue therapy until unequivocal clinical disease 
progression, unacceptable toxicity, until in the opinion of the investigator 
the subject is no longer benefiting from therapy, or at the subject’s 
discretion.

Abbreviation or Term 
Definition/Explanation 
Study Day 1 
First day that protocol-specified IP is administered to the subject. 
End of Treatment 
The date of the last dose of ABI-009 or pazopanib, whichever is later 
for an individual subject. 
End of Treatment Visit 
For a subject is when safety assessments and procedures are 
performed after the last treatment, which should occur within 1 
week (±3 days) after the last dose of ABI-009 or pazopanib, 
whichever is later.  
30 Day Follow-Up Visit 
For a subject is when safety assessments and procedures are 
performed after the End of Treatment visit. The 30-Day Follow-Up 
visit should occur 30 days (+/- 7 days) after the last dose of ABI-009 
or pazopanib, whichever is later. 
End of Study 
 
Either the date of the last visit of the last subject to complete the 
study, or the date of receipt of the last data point from the last 
subject that is required for primary, secondary, and/or exploratory 
analysis, as pre-specified in the protocol.  
Follow-up Period 
 
The on-study time period after the 30-Day Follow-Up Visit. All 
subjects that discontinue study drug and have not withdrawn full 
consent to participate in the study will continue in the follow-up 
phase for survival and initiation of new anticancer therapy. Follow

INTRODUCTION 
1.1. 
Soft Tissue Sarcomas 
Soft tissue sarcoma (STS) is a relatively rare and histologically diverse neoplasm of mesenchymal 
origin, occurring with an incidence of about 1% of all adult cancers, and includes >70 histologic 
subtypes.1-3  For localized resectable disease, surgical resection is the standard of care, and for 
unresectable sarcomas, radiation therapy is offered. However, recurrence rate is high (~50%) and 
treatment options for metastatic/relapsed STS are limited to anthracycline-based chemotherapy 
(i.e., doxorubicin), administered alone or in combination with alkylating agents (ifosfamide 
and/or dacarbazine).4-6 However, drug resistance and toxicities often limit beneﬁts of 
chemotherapy used to treat metastatic sarcomas. 
Recently, in 2015, 2 therapeutics were approved by the United States Food and Drug 
Administration (US FDA) for STS, pazopanib (Votrient®, Novartis Pharma) and trabectedin 
(Yondelis®, Janssen Biotech, Inc.). Pazopanib is a multiple tyrosine kinase inhibitor (TKI), which 
hinders growth factor-mediated signal transduction pathways involved in tumor angiogenesis, 
and was approved for nonadipocytic STSs refractory to chemotherapy.7-9 Trabectedin, a natural 
alkaloid which interferes with gene transcription and DNA repair, was approved for liposarcoma 
and leiomyosarcoma.10,11 Although the new therapeutic options offer improvement of the course 
of disease in specific subtypes of STSs, the prognosis of advanced disease has remained uniformly 
poor, with an estimated median survival of only 8 to 13 months,12-14 and more efficacious 
therapeutics options are needed. 
1.1.1 mTOR Inhibition in Soft Tissue Sarcoma 
Aberrant signaling of the mammalian target of rapamycin (mTOR) pathway is common in 
sarcomas and other malignancies. A multicenter, open-label, single-arm, phase 2 trial with oral 
ridaforolimus, an mTOR inhibitor, showed evidence of activity in sarcomas.15 A total of 212 
heavily pretreated subjects were treated in 4 separate histologic cohorts of STS; 61 subjects 
(28.8%) achieved disease control rate (DCR, defined as subjects who achieved complete response 
(CR) or partial response (PR) or stable disease (SD) for ≥16 weeks). Median progression-free 
survival (PFS) was 15.3 weeks; median overall survival (OS) was 40 weeks, which compared 
favorably to historical metrics. The conﬁrmed overall response rate (ORR) was 1.9%, with 4 
subjects achieving conﬁrmed PR (2 with osteosarcoma, 1 with spindle cell sarcoma, and 1 with 
undifferentiated pleomorphic sarcoma [formerly malignant ﬁbrous histiocytoma]). Related 
adverse events (AEs) were generally mild or moderate and consisted primarily of stomatitis, 
mucosal inﬂammation, mouth ulceration, rash, and fatigue, all typical of the rapalogs. 
Based on promising results from phase 2, a large randomized placebo-controlled phase 3 trial (N 
= 711) evaluated ridaforolimus to assess disease control in advanced sarcomas after benefit from 
prior chemotherapy.16 Subjects with metastatic soft tissue or bone sarcomas who achieved 
objective response or SD with prior chemotherapy were randomly assigned to receive 
ridaforolimus 40 mg or placebo once per day for 5 days every week. Ridaforolimus treatment led 
to a modest, although signiﬁcant, improvement in PFS per independent review compared with 
placebo (hazard ratio [HR], 0.72; P < 0.001; median PFS, 17.7 v 14.6 weeks). Ridaforolimus 
induced a mean 1.3% decrease in target lesion size vs a 10.3% increase with placebo (P < 0.001).

Final Protocol v5.0: July 28, 2022 
Median OS with ridaforolimus was modest: 90.6 weeks versus 85.3 weeks with placebo (HR, 0.93; 
P = 0.46). Adverse events were more common with ridaforolimus than with placebo and were as 
expected with mTOR inhibition, including stomatitis, infections, fatigue, thrombocytopenia, 
noninfectious pneumonitis, hyperglycemia, and rash. Grade 3 AEs were 64% vs 26% for 
ridaforolimus vs placebo, respectively. While there was no associated survival benefit, the trial 
provided proof of principle that mTOR inhibition could demonstrate clinical activity in STS. 
Other mTOR inhibitors, including sirolimus and everolimus, have also been tested in clinical trials 
for advanced STS as single-agents or as part of a combination regimen, producing modest 
improvement. While rapamycin and analogs (rapalogs) are promising therapeutics for the 
treatment of sarcomas, they have low water solubility (hydrophobic), limiting their 
bioavailability. Oral agents, such as rapamycin, everolimus, or ridaforolimus are primarily 
eliminated via hepatic clearance, which result in negligible drug levels in most organs, limiting 
their therapeutic potential. Temsirolimus, a prodrug of rapamycin requiring conversion by 
CYP3A, has higher water solubility than the oral agents but still require solvents (polysorbate 80, 
polyethylene glycol, and dehydrated alcohol) for the injectable formulation. Solvents reduce drug 
efficacy due to micellar sequestration and thus, improved formulations are needed that are both 
solvent-free and allow high bioavailability in order to unleash the full potential of mTOR 
inhibitors. 
A novel mTOR inhibitor ABI-009 (albumin-bound rapamycin nanoparticles, nab-rapamycin) is 
solvent-free and has relatively high bioavailability, and is a promising new therapeutic for 
sarcoma. 
1.2. 
Nab-Sirolimus Background 
1.2.1. 
Rapamycin and Rapalogs 
Rapamycin is a protein kinase inhibitor that is approved for immunosuppression in renal 
transplant subjects and is under investigation as a cancer treatment. Rapamycin inhibits mTOR, 
a regulatory protein kinase in cancer that recognizes high stress levels, including depleted 
nutrient levels and states of hypoxia.17 mTOR is a serine/threonine-specific protein kinase, 
downstream of the phosphatidylinositol 3-kinase (PI3K)/Akt (protein kinase B) pathway, and a 
key regulator of cell survival, proliferation, and metabolism. Additionally, mTOR is involved in 
regulating angiogenesis by controlling endothelial and smooth muscle cell proliferation via the 
hypoxia-inducible factor-1α and vascular endothelial growth factor (VEGF).18 Consistent with its 
role in cell proliferation, the mTOR pathway is frequently overactivated in a number of human 
malignancies, and is thus considered to be an attractive target for anti-cancer therapy. 
Rapamycin and its analogs (rapalogs) function as allosteric inhibitors of mTORC1. Rapalogs are 
currently used in the treatment of advanced renal cell carcinoma and other tumors.19 
Although rapamycin (sirolimus) is an efficacious mTOR inhibitor, it has poor solubility, low oral 
bioavailability, and produce dose-limiting toxicities (DLTs), including mucositis and stomatitis.17,20 
Marketed rapamycin analogs are temsirolimus and everolimus. Temsirolimus, a prodrug of 
rapamycin, is approved for the treatment of kidney cancer. Everolimus is approved for pediatric 
and adult subjects with subependymal giant cell astrocytoma, for advanced hormone receptor-
positive, HER2-negative breast cancer in combination with exemestane, progressive

neuroendocrine tumors of pancreatic origin (PNETs), subependymal giant cell astrocytoma 
(SEGA) associated with tuberous sclerosis and advanced renal cell carcinoma after failure of 
treatment with sunitinib or sorafenib.21-25 
Oral rapamycin and currently available rapalogs induce common side effects including 
hypertension, maculopapular rash (75%), mucositis (50%), asthenia (40%), nausea (43%), 
thrombocytopenia, metabolic abnormalities and more rarely pneumonitis (8%, 3% grade 3) 
sometimes fatal.26-28 The most frequently occurring grade 3 or 4 AEs were hyperglycemia (17%), 
hypophosphatemia (13%), anemia (9%), and hypertriglyceridemia (6%).29 These side effects lead 
to the discontinuation of the treatment in 60% of subjects in some studies. 
1.2.2. 
Nab-Sirolimus (ABI-009, nab-Rapamycin) 
The novel nanoparticle albumin-bound rapamycin (nab-Sirolimus, nab-rapamycin, ABI-009) is 
freely dispersible in saline and is suitable for intravenous (IV) administration, and has produced 
both a favorable safety profile and evidence of efficacy in subjects with metastatic solid tumors.30 
Nanoparticle albumin-bound or nab® technology (Abraxis Bioscience, a wholly-owned subsidiary 
of Celgene Corporation) when applied to hydrophobic molecules, such as paclitaxel (nab-
paclitaxel; Abraxane®), has led to improved drug delivery, safety, and efficacy in various solid 
tumors compared with the conventional paclitaxel formulation.31 This suggests that the nab 
formulation of rapamycin may also produce similar advantages over the standard rapamycin. 
The nab technology may enhance tumor penetration and accumulation via the albumin receptor-
mediated (gp60) endothelial transcytosis. Albumin is highly soluble, has long plasma half-life, 
broad binding affinity, and accumulates in tumors, making it an ideal candidate for drug 
delivery.32,33 Albumin circulating in the bloodstream can interact with gp60 to initiate caveolae-
mediated transcytosis to reach tumor cells.34,35 Indeed, nab-paclitaxel transcytosis across the 
epithelial monolayer was dependent on caveolae formation.36 In accordance with these 
observations, at equal doses, nab-paclitaxel showed greater selectivity to tumors compared with 
solvent-based paclitaxel, which is likely attributed to the biologically active ingredient albumin 
and lack of solvent.36 
Additionally, a study previously published by our group examined the prognostic implications of 
expression of the Serum Protein Acidic and Rich in Cysteine (SPARC) in sarcomas.37 We found that 
elevated SPARC expression, found in about 50% of a random selection of cases, was associated 
with a particularly adverse prognosis, as compared to those with low expression. SPARC has been 
hypothesized as a potential receptor of nanoparticle-albumin encapsulated drug preparations, 
making nab-Sirolimus a promising targeted mTOR for the treatment of STSs.  
1.2.3. 
Preclinical Studies with nab-Sirolimus 
Preclinical primary pharmacology studies in vivo demonstrated significant antitumor activity of 
nab-Sirolimus as a single agent administered intravenously at 40 mg/kg, 3 times weekly for 4 
weeks, across different tumor xenograft models in nude mice (see Figure 1 below), including 
breast, colorectal, multiple myeloma, and pancreatic cancer.38-42 This dose level correlates to 
approximately 360 mg/m2/week in human. These findings are consistent with published 
information on rapamycin as an mTOR inhibitor and the role of mTOR in tumor growth.43 In

addition, recent preclinical study has demonstrated that combination of nab-Sirolimus with the 
Akt inhibitor perifosine induced synergistic antitumor activity and prolonged survival compared 
with either agent alone in multiple myeloma.41 
Figure 1: 
Antitumor Activity of nab-Sirolimus in Tumor Xenografts 
 
Preclinical pharmacokinetic (PK) studies in rats showed that IV nab-Sirolimus exhibited linear PK 
with respect to dose and large volume of distribution (Vz), due to efficient tissue extraction of 
rapamycin from the central blood compartment.40 Shortly after dosing, tissue rapamycin level 
was 3-5 folds higher than that of blood, indicating efficient extraction. The terminal half-life of 
nab-Sirolimus was long in rats, ranging from 13.4 - 25.8 hours and resulted in significant blood 
level at 48 hours (~10 ng/mL) and 120 hours (>1 ng/ml). Consistent with rapamycin literature,44 
excretion of ABI-009 was primarily through the fecal route (68.57 - 69.99%) with minimum 
contribution from the renal route (7.73 - 8.84%). 
The safety and toxicity of nab-Sirolimus were evaluated in a series of preclinical studies. In a 
Good Laboratory Practice (GLP) repeat-dose toxicity study in male and female rats, nab-
Sirolimus administered IV was well tolerated at doses up to 90 mg/kg (equivalent to 540 mg/m2

Sirolimus showed no new or unexpected toxicity compared to what is already known for 
rapamycin and other rapalogs.45-47  Refer to the Investigator's Brochure for details on preclinical 
studies. 
1.2.4. 
Clinical Studies with nab-Sirolimus 
In a phase 1 dose-finding, tolerability, and PK study conducted at MD Anderson Cancer Center 
(Protocol CA401, NCT00635284), nab-Sirolimus was well tolerated with evidence of responses 
and SD in various solid tumors including renal cell carcinoma and bladder cancer, both of which 
typically express mTOR.30 Twenty-six subjects were treated with 45, 56.25, 100, 125, or 150 
mg/m2 nab-Sirolimus per week for 3 weeks, followed by a week of rest (28-day cycle, q3/4w). 
ABI-009 was administered IV. The maximum tolerated dose (MTD) was established at 100 mg/m2. 
Nineteen subjects were evaluable for efficacy. One subject in the 45 mg/m2 (95 mg actual 
rapamycin dose) cohort diagnosed with adenocarcinoma of the kidney and with bone and 
intrathoracic metastases had a confirmed PR. The target lesion of this subject was reduced by 
35.1% and the duration of response (DOR) lasted 183 days. Two (11%) subjects (at doses 45 and 
125 mg/m2, with actual rapamycin doses of 88 mg and 193 mg, respectively) had an overall tumor 
evaluation of SD (confirmed): 1 subject with mesothelioma had SD for 365 days and 1 subject 
with a neuroendocrine tumor in the left axillary node had SD for 238 days.  
In the phase 1 study described above, for all cohorts and all grades, 25 of 26 (96%) subjects 
experienced at least 1 treatment-related AE (TRAE). The most common nonhematological TRAEs 
were mucosal inflammation (10 subjects, 38%), fatigue (7 subjects, 27%), rash (6 subjects, 23%), 
diarrhea (6 subjects, 23%), and nausea (5 subjects, 19%). Specifically, at the MTD of 100 mg/m2, 
all 7 subjects experienced at least 1 TRAE of any grades, and the most common AEs were 
thrombocytopenia, mucositis and fatigue (5 subjects, 71% each). A total of 7 subjects (27%) in 
the CA401 study had treatment-related infections, including candidiasis, oral candidiasis, 
cellulitis, folliculitis, and urinary tract infection. All these events were grade 1 or 2. Four (15%) 
subjects experienced at least 1 treatment-related serious AE (SAE), including cardiac arrhythmia 
(grade 2), failure to thrive (grade 3), and mood alteration (grade 3) both in the 125 mg/m2 cohort, 
vomiting (grade 3) in the 45 mg/m2 cohort, and dyspnea (grade 3) in the 100 mg/m2 cohort. 
The most common hematologic TRAEs, for all cohorts and grades, were thrombocytopenia (58%), 
followed by hypokalemia (23%), anemia and hypophosphatemia (19% each), and neutropenia 
(15%). Most of these events were grade 1/2, and only 1 grade 4 hematologic event occurred 
(thrombocytopenia in the 150 mg/m2 arm). At the MTD, the only hematologic AE was a grade 3 
anemia. In this clinical study, 16 of 26 subjects (62%) had treatment-related AEs (TRAEs) requiring 
a week dose delay.  
Currently, there are several ongoing trials investigating the safety and efficacy of single-agent 
nab-Sirolimus in various disease areas, including a basket trial in subjects with pathogenic 
inactivating TSC1 or TSC2 alterations (NCT05103358). The particularly safe toxicity profile of nab-
Sirolimus allows this mTOR inhibitor to be combinable with other therapeutics and a trial in 
subjects with advanced STS is complete and evaluating the combination of nab-Sirolimus and 
nivolumab (NCT03190174). Refer to the Investigator's Brochure for details on clinical studies.

Pazopanib in Soft Tissue Sarcoma 
Angiogenesis has been explored as a potential target for the treatment of STS.48 A variety of 
multi-targeted TKIs with prominent anti-angiogenic activity (aa-TKI’s) have been studied, 
including pazopanib, with evidence of clinically significant activity.   
Pazopanib was initially approved for the treatment of advanced renal carcinoma and more 
recently, based on a phase 3 randomized trial, as salvage therapy in subjects with advanced, 
nonadipocytic STS.8 In that registrational placebo-controlled, randomized phase 3 study, 
pazopanib demonstrated improved PFS vs placebo in pretreated subjects (median 4.6 vs 1.6 
months; HR=0.31; P < 0.0001).8 Overall survival was not significantly improved and the ORR was 
relatively low (6% pazopanib vs 0% placebo). The most common AEs were fatigue (65% vs 49%), 
diarrhea (58% vs 16%), nausea (54% vs 28%), weight loss (48% vs 20%), and hypertension (41% 
vs 7%) in the pazopanib vs placebo arms, respectively. Although approved for management of 
STS, the activity of pazopanib monotherapy is admittedly modest, with considerable toxicity 
profile.  
A meta-analysis showed evidence that aa-TKIs, including pazopanib, demonstrated improved 
median PFS and ORR vs placebo for the treatment of sarcomas; however, there was no difference 
in the median PFS, median OS, and ORR of pazopanib vs other aa-TKIs.49 Similar to the 
registrational phase 3 study, the meta-analysis also failed to show improvement in median OS 
for aa-TKIs compared with placebo.  
The identification of sarcoma subtypes with particular sensitivity to aa-TKI, along with 
appropriate combination therapies to increase the overall activity in STSs remains an unmet 
need.  
1.4. 
Rationale for Combination of nab-Sirolimus with Pazopanib for Nonadipocytic Soft 
Tissue Sarcoma 
The feasibility to combine an mTOR inhibitor (everolimus) with an aa-TKI (vandetanib) had been 
demonstrated in a phase 1 study in subjects with bone and STSs (N = 21).50 Median PFS and OS 
were 4.5 and 13.9 months, respectively. Two subjects (9.5%) had a CR. These results favorable 
compared with the results from the meta-analysis, in which aa-TKIs produced 3.2 and 11.8 
months of median PFS and OS, respectively, and 5% ORR.49 These results provided proof-of-
concept for the potential to improve efficacy outcomes for subjects with STS with the 
combination of an aa-TKI and an mTOR inhibitor. 
Based on the promising results from the phase 1 study with everolimus combined with 
vandetanib,50 the acceptable toxicity profile of single agent nab-Sirolimus along with evidence of 
antitumor activity in various solid tumors,30 it is plausible that nab-Sirolimus with an aa-TKI may 
potentially offer clinical benefits for subjects with STS. Based on a phase 3 study, PALETTE,8 
pazopanib is now a standard of care for subjects with advanced nonadipocytic STS. Here, we 
propose a phase 1/2 assessment of the safety and antitumor activity of the combination of nab-
Sirolimus with pazopanib for subjects with advanced nonadipocytic STSs.  Given non-overlapping 
toxicity profiles, we hypothesize that combining the 2 drugs will be feasible.

1.5. 
Rationale for Starting Dose Selection and Schedule of nab-Sirolimus and Pazopanib 
The established MTD of single-agent nab-Sirolimus for subjects with advanced solid tumors is 
100mg/m2. In the initial cohorts of nab-Sirolimus with pazopanib, the planned starting dose of 
60 mg/m2 ABI-009 [given IV weekly for 2 weeks with a week of rest (q2/3w)] gave a 40% safety 
margin over the established MTD of 100 mg/m2 for subjects with advanced solid tumors 
adipocytic. This dose, assuming a BSA of 1.7, is 102 mg/week (or 68 mg/week on average in a 3-
week cycle), which is within or above the therapeutic range for rapalogs:   
• Rapamune (oral rapamycin) dosing used chronically for transplant subjects is similar to 
the proposed starting dose of nab-Sirolimus.46 Rapamune is dosed at 2-5 mg/day, which 
is 14-35 mg/week. Safety profiles of everolimus and Rapamune are similar. Everolimus 
dosing levels47 are similar to Rapamune dosing, with both being in the same range as 
the planned starting dose of ABI-009. 
• Using the PK data from the phase 1 study30, linear modeling of rapamycin blood 
concentration predicts that 1 week after 10 and 20 mg/m2 nab-Sirolimus IV 
administration, therapeutic trough rapamycin levels are still maintained (7.11 and 14.22 
ng/mL, respectively, Aadi data on file). Thus, potential dose reduction from the starting 
dose of 60 mg/m2 should still result in therapeutic levels. 
• Nab-Sirolimus has shown similar safety profile to other rapalogs, even at a higher dose 
of 100 mg/m2, with no new or unexpected toxicity had been observed. In particular, 
mucositis/stomatitis that were observed with other mTOR inhibitors has not been dose-
limiting with nab-Sirolimus. 
The q2/3w schedule allowed 2 additional drug holidays in 6 months than the q3/4w schedule 
studied in the first-in-human study for nab-Sirolimus (CA401, NCT00635284), allowing more 
time for recovery from potential AEs and is more convenient for subjects. 
A recommended phase 2 dose (RP2D) could not be established in the initial dosing cohorts in 
this present study, after treating 13 subjects. DLTs were observed in all dose cohorts, with the 
most prominent DLT being thrombocytopenia. Despite DLT, subjects have been able to tolerate 
therapy after dose adjustment (dose reductions and delays): only 3 of the first 13 subjects 
enrolled discontinued therapy due to adverse events. Two patients experienced grade 3 and 4 
thrombocytopenia after a single dose of nab-Sirolimus and missed Cycle 1 Day 8, subsequently 
recovered from the event, and were able to resume therapy. Additionally, 10/13 (77%) patients 
experienced myelosuppression during the first cycle, 6 of them had a delay of the next planned 
cycle, D1. Together missed Day 8 doses and dose delays of Day 1 occurred in nearly all patients 
(12/13, 92%) at some point during the treatment course, resulting in 3-week gap between 
dosing, which allowed resolution of AEs and continuous therapy.  These results lead to the 
conclusion that administration of the combination may be feasible but require optimization of 
the q2/3w schedule; and therefore, a new cohort set will explore a q1/3w schedule, i.e. nab-
Sirolimus dosing on Day 1 of a 3-week cycle.    
Assessment of clinical activity of this combination in STS is a secondary objective.  Two of the 13 
subjects enrolled in the initial phase I assessment experienced objective partial responses, in

22

spite of the dose modifications described above. The objective evidence of clinical activity 
further justifies continued efforts to identify a RP2D. 
For further dose-finding studies, nab-Sirolimus will be administered at a starting dose of 30 
mg/m2 every three weeks.  Dose escalation will be in steps, either down to 20 or 15 mg/m2, or 
incrementally increasing to 45, 60, 75 and 100 mg/m2 administered on day 1 of a 21-day cycle.  
This dose range, assuming a BSA of 1.7, yields dose intensity in the range of 8.5-56 mg/wk.  While 
lower than expected in the initially planned dosing schema with q2/3w dosing, this range of dose 
intensity closely approximates that anticipated with rapalogs. In this study, pazopanib will be 
given as standard of care. The starting dose was 800 mg orally once daily without food (at least 
1 hr. before or 2 hrs. after a meal), and is reduced to 400 mg orally once daily.52  In our initial 
experience combining nab-Sirolimus with pazopanib, thrombocytopenia emerged as an apparent 
dose limiting toxicity when pazopanib was administered the daily dose of 800 mg recommended 
by the package insert.52  Thrombocytopenia can be observed with both agents.  We noted with 
several subject that dose reductions of pazopanib to either 400 or 600 mg daily allowed 
administration of nab-Sirolimus.  Of the 2 doses, 400 mg of pazopanib daily appeared to be 
consistently compatible with nab-Sirolimus, whereas subjects receiving 600 mg daily have 
required additional dose reductions to 400 mg daily.  In our further investigation of this 
combination, we propose continuing our investigations at a dose of 400 mg of pazopanib daily. 
Selection of 400 mg of pazopanib as the starting dose for investigation is reasonable.  The 
package insert for pazopanib recommends that “initial dose reduction should be 400 mg, and 
additional dose decrease, or increase should be in 200 mg steps based on individual tolerability.” 
In addition, a subgroup analysis of subjects from the original pazopanib registration trial for soft-
tissue sarcomas has recently been published.53  Dose reductions and dose interruptions were 
reported in 32% (77/240) and 42% (101/240) of those available for analysis.  Thus, changes to 
planned study treatment were frequent due to toxicity from pazopanib. Critically, neither dose 
reductions nor dose interruptions of pazopanib were associated with inferior progression free 
survival in the Intent-to-Treat population.  Specifically, the authors addressed dosing at 400 and 
600 mg daily.  Within the study population, those receiving “…a daily dose between 400 and 600 
mg had higher…[median Progression-Free Survival] then subjects receiving a daily dose between 
600 and 800 mg or a daily dose of less than 400 mg….”53.  While the longer progression-free 
survival among those receiving lower doses of pazopanib likely reflects some element of selection 
bias, the key point is that the lower doses were not associated with worsened progression-free 
survival, the primary endpoint of the study.  Thus, it is reasonable to use a starting dose of 400 
mg of pazopanib as we continue to investigate the combination with nab-Sirolimus.

Study Design 
This is an open label, dose-finding, single-arm, prospective phase 1/2 study to identify the RP2D 
of nab-Sirolimus given IV on either Day 1 and Day 8, or Day 1 only of a 21-day cycle (q2/3w), plus 
daily oral pazopanib in subjects with advanced nonadipocytic STS. The target DLT rate is ≤20%. 
The study will be conducted in compliance with International Conference on Harmonisation (ICH) 
Good Clinical Practices (GCPs). 
Dose-finding Phase 1 Portion of the Study:   
Dose levels of nab-Sirolimus will be tested in cohorts of 3 subjects each using the 3+3 dose-finding 
design. Potential doses of nab-Sirolimus are contained below in Table 1 and Table 2. All cohorts 
in Table 1 are considered completed. As of this amendment, new enrollments will follow the 
cohort schedule in Table 2.

After enrollment of the first 3 dose cohorts (0, -1, and -2) an RP2D had not yet been identified. 
DLTs were observed in all three of these enrolled cohorts. A total of 16 subjects were consented 
resulting in 13 enrollments and 3 screen failures. DLTs were observed at all dose levels. A 
summary of DLTs observed in Cohorts 0, -1, and -2 are provided below in Table 3. Of the 13 
subjects enrolled, 11 subjects had nab-Sirolimus and/or pazopanib dose reduced, and three 
subjects discontinued due to toxicity.

Starting dose of pazopanib must remain consistent within each cohort but may be adjusted 
during treatment as needed due to toxicity. Protocol Amendment 3 added the option for 
additional cohorts, and modified the dosing schedule from Day 1/8 to Day 1 only of a 21-day cycle 
as summarized in Table 1 and Table 2. The starting dose  began at 30 mg/m2 of nab-Sirolimus on 
Day 1 and pazopanib at 400 mg daily (Cohort 0C). Starting with Amendment 3, the dose finding 
portion of the study was re-initiated, enrolling 3 subjects at 30 mg/m2 of nab-Sirolimus and 400 
mg of pazopanib with Day 1 dosing only. Cohort 0C and subsequent cohorts  followed the same 
dose-finding and DLT rules outlined below. 
The dose levels of nab-Sirolimus will be tested in cohorts of 3 subjects each using the 3+3 dose-
finding design. The starting doses for each cohort and potential escalation or de-escalation are

Final Protocol v5.0: July 28, 2022 
summarized in Table 1 and Table 2. If no DLT is observed during the first 2 cycles at the starting 
dose in the first 3 subjects, the next dose cohort would enroll subjects at the next highest dose 
level. If no DLT is observed at the first 3 subjects at the higher dose level, the next dose cohort 
would continue to escalate to the next highest dose level, up to a maximum of 100 mg/m2. If 1 
DLT is observed any dose cohorts in the first 3 subjects, then the cohort will expand, and an 
additional 3 subjects will be enrolled at that dose level. The first three subjects in a given cohort 
must complete the DLT window prior to expanding to include the additional 3 subjects. If ≤1 of 6 
subjects experience a DLT at the starting dose or higher, enrollment would continue to the next 
higher dose level. 
If ≥2 subjects experience a DLT at dose level higher than the starting dose, enrollment will be 
discontinued for that dose cohort and the previous dose level would be declared the MTD. If ≥2 
subjects experience a DLT at the starting dose of a given cohort, further enrollment at that dose 
level will be discontinued and nab-Sirolimus will be reduced to the next planned dose level, to a 
lower limit dose level of 15 mg/m2. The MTD of nab-Sirolimus combined with pazopanib is the 
highest nab-Sirolimus dose level at which ≤1 of 6 (or 0 out of 3) subjects experienced a DLT, thus 
a target DLT rate of roughly 17%. RP2D is identified based of the totality of safety and efficacy 
data. 
Phase 2 Portion of the Study:  
This will be conducted using a Simon’s two-stage design. Subjects enrolled in the phase 1 study 
at the RP2D cohort will be included for response and safety evaluation in phase 2. 
2.4. 
Study Duration, End of Study, End of Treatment, End of Treatment Visit, Follow-up 
Period 
The study is expected to take approximately 36 months from first subject enrolled to last subject 
follow-up, including approximately 30 months of enrollment period, an estimated 6 months of 
treatment (or until treatment is no longer tolerated).   
End of Treatment (EOT) for a subject is defined as the date of the last dose of nab-Sirolimus or 
pazopanib, whichever is later. Single agent continuation of nab-Sirolimus is permitted. If a subject 
must discontinue nab-Sirolimus treatment, they will be discontinued from the study. End of 
Treatment Visit for a subject is when safety assessments and procedures are performed after the 
last treatment of nab-Sirolimus or pazopanib, whichever is later (+/- 3 days).   
The 30-Day Follow-Up Visit for a subject is defined as the date when safety assessments and 
procedures are performed after the End of Treatment visit. The 30-Day Follow-Up visit should 
occur 30 days (+/- 7 days) after the last dose of nab-Sirolimus or pazopanib, whichever is later. 
The End of Study (EOS) defined as either the date of the last visit of the last subject to complete 
the study, or the date of receipt of the last data point from the last subject that is required for 
primary, secondary, and/or exploratory analysis, as pre-specified in the protocol.  
Follow-up period is the on-study time period after the 30-Day Follow-Up Visit. All subjects that 
discontinue study drug and have not withdrawn full consent to participate in the study will 
continue in the follow-up phase for survival and initiation of new anticancer therapy. Follow up 
will continue approximately every 12 weeks from the 30-Day Follow-Up Visit (±3 weeks), until

a All visits are allowed to occur in a window of ±3 days unless otherwise specified. 
b Baseline screening visit will be done within 28 days prior to study treatment Day 1. Baseline scans should be completed within 28 days of C1D1, as close to C1D1 as possible.  
c Day 15 visit is only in Cycle 1 and 2. Cycle 3+ does not have a Day 15 visit. 
d End of Treatment-phase (EOT) Visit should be within ±3 days of last study treatment.  
e Thyroid function test to be repeated as needed, based on investigator’s opinion. 
f Subjects who consent for pre-treatment tissue collection for biomarker analysis: either fresh-frozen or formalin-fixed paraffin-embedded (FFPE) tumor blocks or unstained 
slides (min 10). Fresh tissue collection may only be obtained if clinically feasible and without undue risk to the subject. 
g For all female subjects of childbearing potential (see Inclusion 5), a serum pregnancy test will be done at screening. A serum or urine pregnancy test will be repeated within 72 
hours before first treatment if the serum pregnancy test occurred >72 hours before dosing, and at EOT and 30-Day Follow-Up (if applicable). Pregnancy tests conducted after 
screening will be recorded in the source documentation only.  
h Single tracing ECG and lipids evaluations are every even cycle (C2, C4, C6, etc.). Only lipid panel at baseline is required to be fasting lipid. 
i Height is measured only at C1D1. BSA is calculated ONLY on C1D1; to be recalculated only if the weight changes by > 10% in subsequent cycles, at which point the recalculated 
weight will become the new baseline. Vitals signs to include respiration rate, temperature, systolic/diastolic blood pressure, and pulse. Vital signs to be collected Pre-Dose 
(within 15 minutes prior to start of infusion) and Post-Dose (+10 minutes from end of infusion). 
j Rapamycin levels are done locally and for all subjects in Phase 1 at Cycle 1 D8 prior to infusion (within 15 minutes prior to infusion) and on D15 (any time) to assess trough 
levels as well as in Cycle 2, D1 and D8 prior to infusion and on Day 15 (anytime).  
k Baseline scans should be done within 4 weeks of C1D1, preferably as close to first treatment as possible. Every 6 weeks from C1D1 (±1 week) for the first year, then every 12 
weeks (+/- 1 week) until disease progression or last treatment, regardless of missed or out of window doses. End of Treatment Visit CT/MRI should be performed only for those 
subjects that discontinue treatment for a reason other than disease progression. All responses must be confirmed by an additional CT scan after 6 weeks. MRI may be used if CT 
is contra-indicated for a subject. The same mode of imaging at screening must be used consistently throughout the study.  
l Nab-Sirolimus must be administered after all study specific assessments are done in a visit. Pazopanib dosing is daily and oral and may be dosed anytime in relation to ABI-009 
administration. Nursing supervision or documentation of pazopanib dosing on days where nab-Sirolimus is administered is not needed. See Section 6.2 for pazopanib dosing, 
schedule, and administration. Vital signs to be collected Pre-Dose (within 15 minutes prior to start of infusion) and Post-Dose (+10 minutes from end of infusion). There is a 60-
minute observation window post end of infusion for Cycle 1. If a subject completes Cycle 1 with no infusion related reactions, the observation period may be omitted for Cycle 2

PROCEDURES 
5.1. 
Screening Evaluations 
This study will be conducted at the University of Washington, Seattle, USA; other centers may be 
considered to join. Each subject who enters into the screening period for the study receives a 
unique subject identification number before any study-related procedures are performed. The 
subject identification number will be assigned. This number will be used to identify the subject 
throughout the clinical study and must be used on all study documentation related to that 
subject.  
The subject identification number must remain constant throughout the entire clinical study; it 
must not be changed after initial assignment, including if a subject is rescreened.  
Before subjects may be entered into the study, the Sponsor-Investigator requires a copy of the 
written IRB/IEC approval of the protocol, informed consent form, and all other subject 
information and/or recruitment material, if applicable. A signed and dated Institutional Review 
Board (IRB) approved informed consent form (latest approved version) must be obtained from 
each subject prior to performing any study-specific procedures. All subjects must personally sign 
and date the consent form before commencement of study-specific procedures.  
Screening evaluations will be performed for all subjects to determine study eligibility.  These 
evaluations must be obtained ≤28 days prior to enrollment. Baseline imaging should be obtained 
as close to initiation of protocol therapy as possible. Any questions regarding subject eligibility 
should be directed to the Sponsor-Investigator for approval. 
The following procedures are to be completed during the screening period, after signed informed 
consent has been obtained, designated in the Schedule of Assessments found in Table 4 and 
Table 5. 
• Demographics (if allowed by local regulations, date of birth, sex, race, and ethnicity) 
• Physical examination (including medical/cancer history, ECOG performance status 
assessment, weight)  
• Prior/concomitant medications and procedures evaluation to include all medications 
taken ≤28 days prior to date of informed consent  
• Vital signs (temperature, sys/dias blood pressure, respiration rate, and pulse) 
• ECG   
• Left ventricular ejection fraction (LVEF, by echocardiogram or MUGA) 
• Local Laboratory Assessments: chemistry, complete blood count (CBC with 
differential, platelet count, urinalysis, pregnancy test (women of child-bearing 
potential, includes tubal ligations), thyroid panel (TSH, T3, T4), HIV, hepatitis B surface 
antigen, hepatitis B core antibody (HBV cAb), hepatitis C antibody, lipids 
• CT or MRI, must be done within 28 days of C1D1, but preferably should be done as 
close to the day of enrollment as possible

Response Assessment  
Tumor response will be assessed by CT or MRI scan of the chest, abdomen, and pelvis (CAP) per 
institutional guidelines; image preparation and evaluation will follow the specifications provided 
in the RECIST version 1.1. The same modality (CT or MRI) must be used at screening and 
throughout the study.  
CT/MRI scans to be performed at the following frequency: 
• ≤4 weeks prior to C1D1 (as close to C1D1 as possible) (screening) 
• Followed by every 6 weeks from C1D1 (± 1 week) for the first year; then every 12 
weeks (± 1 week) until disease progression or unacceptable toxicity. End of Treatment 
Visit CT/MRI should be performed only for those subjects that discontinue treatment 
for a reason other than disease progression. 
An unscheduled scan for suspected disease progression may be performed at any time. However, 
adherence to the planned imaging schedule is critical regardless of dose delays or unscheduled 
or missed assessments. Determination of disease progression for clinical management of 
subjects on study will be assessed at the local site. If an initial observation of objective response 
(CR or PR) is made, a confirmation scan should be done at 6 weeks after initial observation.  
5.3.

6.1.2. 
Nab-Sirolimus Dose Modification and Stopping Rules 
If treatment cannot be administered on the planned visit date, nab-Sirolimus may be 
administered ±3 days from the scheduled date. Prior to nab-Sirolimus administration, subjects 
must meet the following hematological requirements for dosing on every dosing day: 
• ANC ≥1.5 x 109/L 
• Platelet count ≥100 x 109/L 
• Hemoglobin ≥9.0 g/dL 
The treatment may be held (delayed) up to 21 days due to toxicity. Treatment may also be 
interrupted for situations other than treatment-related AEs such as medical/surgical events or 
logistical reasons not related to study therapy. Participants should be placed back on study 
therapy within 21 days of the scheduled interruption, unless otherwise discussed with the 
Sponsor-Investigator. The reason for interruption should be documented in the subject’s study 
record. 
If the dose held or missed was to be Day 1 of the next cycle, the next cycle will not be 
considered to start until the day the first dose is actually administered to the subject. 
If the subject is dosing on a q2/3w schedule, if the dose held or missed was to be Day 8, that 
week becomes the week of rest. Next dose becomes Day 1 of a new cycle. The cycle with the 
missed Day 8 dose would become 14 days long versus the normal 21-day cycle. If the cycle with 
the missed Day 8 dose is Cycle 1 or Cycle 2, the Day 15 visit would also be omitted. If the 
subject is dosing on a q1/3w schedule, a cycle is not considered to have begun until the subject 
receives the Day 1 dose. If the subject misses a Day 8 or Day 15 visit, the cycle continues 
without interruption and the visits are recorded as missed. The following cycle is considered to 
have begun when the subject receives their next dose. 
In the event of clinically significant AE in any part of the study, treatment may be held, and 
supportive therapy administered as clinically indicated. If the toxicity or event is not grade 3/4 
and resolves to baseline or grade 1 in less than or equal to 21 days of stopping therapy, then 
treatment may be restarted.  
Dose reduction of nab-Sirolimus to the next lower dose level should be considered as clinically 
indicated for subjects who are receiving nab-Sirolimus at above the lowest dose level. In phase 
1, once a dose has been reduced, it may not be increased to the previous level. In phase 2, if an 
AE resolves to grade 1 or baseline at the reduced dose level, and no additional toxicities are seen 
during the following cycle of study treatment at the reduced dose, the dose may be re-escalated 
to the previous dose level.  
The maximum delay between a missed scheduled dose and the next one (whichever dose was 
missed) should not be longer than 21 days. If a dose delay over 21 days is required, Sponsor-
Investigator Approval is required, otherwise the subject should be discontinued. If Sponsor-
Investigator approval is granted, a secondary approval is required to restart study treatment after 
≥21 days of interruption. If the toxicity does not resolve to at least grade 1 in less than 21 days, 
withdrawal from the treatment with the IP is recommended. However, if the investigator and

Nab-Sirolimus Hepatotoxicity Stopping Rules  
Subjects with abnormal hepatic laboratory values (i.e., ALP, AST, ALT, total bilirubin TBL) and/or 
international normalized ratio (INR) and/or signs/symptoms of hepatitis may meet the criteria 
for withholding or permanent discontinuation of nab-Sirolimus as specified in the Guidance for 
Industry Drug-Induced Liver Injury: Premarketing Clinical Evaluation, July 2009. 
6.1.3.1. 
Criteria for Permanent Discontinuation of nab-Sirolimus Due to Potential 
Hepatotoxicity 
Nab-Sirolimus should be discontinued permanently and the subject should be followed for 
possible drug-induced liver injury (DILI), if ALL of the criteria below are met:  
• Total bilirubin >2 x ULN or INR >1.5 x ULN 
• AND increased AST or ALT from the relevant baseline ≥3 x ULN  
• AND no other cause for the combination of the above laboratory abnormalities is 
immediately apparent; important alternative causes for elevated AST/ALT and/or 
total bilirubin values include, but are not limited to: 
− Hepatobiliary tract disease 
− Viral hepatitis (e.g., Hepatitis A/B/C/D/E, Epstein-Barr Virus, Cytomegalovirus, 
Herpes Simplex Virus, Varicella, Toxoplasmosis, and Parvovirus) 
− Right sided heart failure, hypotension or any cause of hypoxia to the liver causing 
ischemia.   
− Exposure to hepatotoxic agents/drugs or hepatotoxins, including herbal and 
dietary supplements, plants and mushrooms   
− Heritable disorders causing impaired glucuronidation (e.g., Gilbert’s Syndrome, 
Crigler-Najjar syndrome) and drugs that inhibit bilirubin glucuronidation 
(e.g., indinavir, atazanavir) 
− Alpha-one antitrypsin deficiency 
− Alcoholic hepatitis 
− Autoimmune hepatitis  
− Wilson’s disease and hemochromatosis 
− Nonalcoholic Fatty Liver Disease including Steatohepatitis (NASH)

>8 x ULN at any time 
>5 x ULN but <8 x ULN for ≥2 weeks 
>5 x ULN but <8 x ULN and unable to adhere to 
enhanced monitoring schedule

• OR: Total bilirubin >3 x ULN at any time 
• OR: Alk Phos >8 x ULN at any time 
Nab-Sirolimus should be withheld pending investigation into alternative causes of DILI. Re-
challenge may be considered if an alternative cause for impaired liver tests (ALT, AST, and ALP) 
and/or elevated TBL is discovered and the laboratory abnormalities resolve to normal or baseline. 
6.2. 
Pazopanib 
6.2.1. 
Dose Levels for Pazopanib 
Pazopanib starting dose may be at either 400 or 800 mg daily. Pazopanib decrease should be in 
200-mg steps,52 for pazopanib-related AEs that require dose reductions (Section 6.2.2). 
Pazopanib dosing may not be reduced below 200 mg daily. Subjects requiring a dose reduction 
below 200 mg daily should discontinue pazopanib therapy. Pazopanib dosing may not be 
increased above 800 mg daily. Dose modification algorithms for specific toxicities are detailed 
below in Section 6.2.2. For all other Grade 3 or 4 non-hematologic toxicities (except alopecia, 
nausea, or vomiting) that are at least in part attributable to the study drug, the dose should be 
held until the toxicity resolves to ≤ Grade 1. Treatment should then be resumed at a reduction 
of one dose level. For recurrent grade 3 or 4 toxicity, the study drug should again be held until 
the toxicity resolves to ≤ Grade 1 and then reintroduced at another dose level reduction. If the 
toxicity has abated with reduction of the dose and dose re-escalation is considered safe by the 
investigator, the study drug dose can then be increased step-wise back to the pre-event dose 
(in 200 mg increments, after monitoring for 14 days at each dose level to ensure that toxicity 
did not recur or worsen). 
Pazopanib is absorbed orally, with median time to achieve peak concentrations of 2 to 4 hours 
after the dose. If a dose is missed, it should not be taken if it is less than 12 hours until next dose. 
For pazopanib dose reduction and stopping rules, please refer to Table 10 and Table 11. 
6.2.2.

Dosing Schedules (D1 vs D1/D8) 
Nab-Sirolimus may be dosed on either Day 1 or Day 1/Day 8 of a 21-day cycle, based on which 
cohort a subject is assigned to. Subjects initially assigned to Day 1/Day 8 dosing may switch to a 
Day 1 only dosing schedule at investigator discretion, after completion of at least two full cycles 
of treatment.  
Subjects initially enrolled on a Day 1 only schedule may not switch the dosing schedule. Once a 
subject has switched a dosing schedule, this change is considered permanent and they may not 
switch back.  
6.4. 
Dose Limiting Toxicity 
Dose-limiting toxicities will be assessed in the first 2 cycles (2, 3-week cycles).  
A DLT is defined as any Grade 3 or greater AE, at least possibly related to either or both nab-
Sirolimus and pazopanib. Only toxicities with a clearly identified and documented alternative 
explanation may be deemed non-DLT. Dose-limiting toxicities include any death not clearly due 
to underlying disease or extraneous causes, or persistent intolerable nonhematologic AE of any 
grade that requires dose reduction or permanent discontinuation of the study-drug, in the 
opinion of the investigator. 
The following adverse events may be excluded from being considered a DLT:  
• Grade 3 nausea/vomiting or diarrhea for less than 72 hours, with adequate antiemetic 
and other supportive care;  
• Grade 3 fatigue for less than 1 week;  
• Grade 3 or higher electrolyte abnormality that lasts up to 72 hours, is not clinically 
complicated, and resolves spontaneously or responds to conventional medical 
interventions. 
• Lab abnormalities that have no clinical sequelae (e.g. febrile neutropenia from low ANC, 
bleeding from thrombocytopenia, etc.) and resolve to grade 1 or better within 7 days will 
not be considered a DLT. 
Nab-Sirolimus dose modification guidelines are outlined in Table 9 and Table 11 for clinically 
significant toxicities that are deemed related to nab-Sirolimus.

STUDY DRUG MANAGEMENT  
7.1. 
Description of Study Drugs  
7.1.1. 
Nab-Sirolimus Packaging, Labeling, and Storage 
Nab-Sirolimus will be supplied Aadi Bioscience in single-use vials as lyophilized product. Each 
single-use 50-mL vial will contain 100 mg rapamycin and approximately 800 mg of human 
albumin as a stabilizer. Each vial will be labeled according to country-specific regulatory 
requirements for labeling of IPs.  
Unopened vials of nab-Sirolimus should be stored in a refrigerator (2°-8°C; 36°-46°F) in original 
cartons to protect from light. Reconstituted nab-Sirolimus may be stored for up to 4 hours at 2-
8°C (36°- 46°F), followed by 4 hours at room temperature (<25°C) in the IV bag. Both unopened 
vials of nab-Sirolimus and reconstituted nab-Sirolimus should be stored in an area free of 
environmental extremes and must be accessible only to study personnel. 
Temperature records for nab-Sirolimus must be made available to Aadi Bioscience or Sponsor-
Investigator approved monitoring teams for verification of proper study drug storage. 
7.2. 
Nab-Sirolimus and Pazopanib Accountability, Disposal, and Compliance 
7.2.1. 
Nab-Sirolimus 
For nab-Sirolimus, only completely unused study drug vials should be retained by the site until a 
representative from Aadi Bioscience or Sponsor-Investigator approved study monitor has 
completed an inventory. Partially used and completely used vials should be destroyed according 
to the site’s guidelines, and their disposition should be recorded on the Investigational Drug 
Accountability Record Form. 
For nab-Sirolimus the Sponsor-Investigator, or designee, shall record the dispensing of study drug 
to subjects and any remaining study drug after dosing in a study drug accountability record. The 
study drug record will be made available to monitoring personnel for the purpose of accounting 
for the study drug supply. Inspections of the study drug supply for inventory purposes and 
assurance of proper storage will be conducted as necessary. Any significant discrepancy will be 
recorded and reported to the Sponsor-Investigator and Aadi Bioscience or their designee and a 
plan for resolution will be documented. 
Accurate recording of all nab-Sirolimus administration will be made in the appropriate section of 
the subject’s CRF and source documents. The Sponsor-Investigator or designee is responsible for 
accounting for all study-specific IP either administered or in their custody during the course of 
the study. 
7.2.2. 
Pazopanib 
Pazopanib is managed as a prescribed medication and administered as standard of care, 
according to institutional practices. 
Accurate recording of all pazopanib administration will be made in the appropriate section of 
the subject’s CRF and source documents. Subjects will complete a daily drug diary recording 
time of self-administration of pazopanib dosing. This diary will be reviewed at Day 1 of each 
cycle. Pharmacy accountability and dispensation records will not be maintained for pazopanib.

CONCOMITANT MEDICATIONS AND PROCEDURES 
All concomitant treatments, including blood and blood products, must be reported on the CRF. 
Throughout the study, investigators may prescribe any concomitant medications or treatments 
deemed necessary to provide adequate supportive care except for those listed in Section 8.2. 
Concomitant therapies are to be collected from 28 days prior to signing of informed consent 
through the 30-Day Follow Up Visit. Therapy name including indication, dose, frequency, route, 
start date and stop date will be recorded on each subject’s CRF(s). 
8.1. 
Permitted Medications and Procedures 
The investigator must be informed as soon as possible about any medication taken from the time 
of screening until the end of the clinical phase of the study (final study visit). Any concomitant 
medication(s), including herbal preparations, taken during the study will be recorded in the CRF. 
The minimum requirement is that drug name, dose, and the dates of administration are to be 
recorded. Additionally, a complete list of all prior cancer therapies will be recorded in the CRF. 
Subjects should receive full supportive care during the study, including transfusions of blood and 
blood products, and treatment with antibiotics, anti-emetics, anti-diarrheas, and analgesics, and 
other care as deemed appropriate, in accordance with their institutional guidelines. WBC growth 
factors may be administered at the discretion of the investigator, consistent with institutional 
guidelines. 
Extreme precaution must be taken with contraceptives (either combined or progesterone only), 
as it is not known if there is the potential of inhibition/induction of enzymes that affect the 
metabolism of estrogens and/or progestins.  
8.2. 
Prohibited Medications and Procedures 
The use of certain medications and illicit drugs within 5 half-lives or 28 days, whichever is shorter, 
prior to the first dose of study drug and for the duration of the study will not be allowed. If a 
prohibited medication is required for single use (such as for a procedure) while study drug is held, 
the Sponsor-Investigator can approve such use. 
The following medications or non-drug therapies are prohibited: 
• Other anti-cancer therapy while on treatment in this study. 
• Antiretroviral drugs (subjects with known HIV are ineligible for study participation). 
• Herbal remedies (e.g., St. John’s wort) unless approval is granted by the Sponsor-
Investigator. 
• Rapamycin is metabolized primarily by CYP3A4. Drugs that are strong inhibitors or 
inducers of CYP3A4 may only be used under special circumstances (e.g., as a single use 
for a procedure) while treatment with study drug is interrupted. The list may be modified 
based on emerging data.  
• Use of any known CYP3A4 substrates with narrow therapeutic window (such as fentanyl, 
alfentanil, astemizole, cisapride, dihydroergotamine, pimozide, quinidine, terfanide)

9.2. 
Safety Analysis 
The safety analysis set includes all treated subjects. 
Safety and tolerability will be monitored through continuous reporting of treatment emergent 
and TRAEs, AEs of special interest, laboratory abnormalities, and incidence of subjects 
experiencing dose modifications, dose delay/dose not given, dose interruptions, and/or 
premature discontinuation of IP due to an AE. All AEs will be recorded by the investigator from 
the time the subject signs informed consent until 30 days after the last dose of protocol therapy. 
Adverse events will be graded by NCI CTCAE v5.0. 
Physical examination, vital signs, laboratory assessments (e.g., serum chemistry, hematology), 
and ECOG performance status will be monitored and reviewed per institutional standards. All 
SAEs (regardless of relationship to IP) will be followed until resolution. Local laboratory analysis 
will be performed as per study schedule.

9.3. 
Efficacy Analysis  
Subjects will be evaluated for ORR, DCR, or progressive disease (PD) by CT imaging. Contrast 
enhanced MRI can also be used if CT is contra-indicated, as long as the same modality is used 
throughout the study. Baseline scan results can be accepted from outside institutions but must 
be done within 4 weeks of starting therapy and must include (as clinically indicated), chest 
abdominal, and pelvic CT or MRI. The first response assessment by CT or MRI scans documenting 
target lesions will be done 6 weeks after C1D1 and should be repeated every 6 weeks for the first 
year, then every 12 weeks thereafter until the end of treatment. If an initial observation of 
objective response (CR or PR) is made, a confirmation scan should be done at 6 weeks after initial 
observation. Scans should continue on schedule regardless of delays in nab-Sirolimus dosing.  
The efficacy endpoints of ORR (CR + PR), DCR (CR, PR, and SD ≥18 weeks), and PFS will be 
determined by a local radiologic assessment using RECIST v1.1. After the 30-Day Follow Up Visit, 
subjects will be followed for survival every 12 weeks (±3 weeks), or more frequently as needed, 
until death, withdrawal of consent, or the study closes, whichever is the earliest. 
The number and percentage of subjects achieving response ORR, DCR, or progressed will be 
summarized.   
Median PFS and OS will be summarized using Kaplan-Meier (KM) analysis. Analysis of other 
efficacy endpoints, PFS rate at 3 and 6 months, and OS rate at 12 months will be assessed via 
descriptive statistics, for the number of subjects is expected to be small. 
Response duration usually will be measured from the time of initial response until documented 
tumor progression. 
9.4. 
Exploratory Analysis 
Presence/level of expression of immune parameters, gene profiling, and SPARC will be analyzed 
and their relationship to clinical responsiveness will be explored. 
9.5. 
Sample Size Considerations 
Phase 1: Up to 49 subjects to identify the MTD, but the MTD may be reach with as few as 22 
subjects. Subjects who discontinue from the study prior to completing the DLT assessment 
window for reasons other than toxicity will be replaced at the same dose level. 
Phase 2: For sample size determination, we assume the following: 
1. For aa-TKI/pazopanib monotherapy in nonadipocytic STS, the baseline anticipated PFS 
rate at 3 months is approximately 50%49.   
2. An increase by the combination therapy of the PFS rate at 3 months to 70% would be 
considered clinically meaningful. 
3. This is an exploratory phase 1/2 study. Thus, type I (false positive) errors are less 
worrisome than type II (false negative). We therefore set alpha=0.1 for rejection of null 
hypothesis. Beta is set at 0.1 (90% power), again, to minimize type II errors. 
4. We are using a Simon’s two-stage study design for the phase 2 efficacy evaluation.

65 
Final Protocol v5.0: July 28, 2022 
In the first stage, at least 23 subjects would be enrolled, including the 3-6 subjects from phase 1 
at the RP2D. If at least 11 were progression-free at the 3 months evaluation, then additional 
subjects would be enrolled to a total of 39 subjects in Phase 2. If at least 23 were progression-
free at 3 months, then this would provide preliminary data to indicate that the combination was 
active and worthy of further evaluation in this clinical setting. 
Subjects who fail to become evaluable for the secondary endpoint with a follow-up CT/MRI will 
be replaced. 
To assess the primary endpoint, we elected to use a Simon’s minimax design52. This was selected 
to be most conservative in evaluable subjects needed to answer the primary hypothesis. In this 
case, a total of 39 evaluable subjects will be required in the phase II component of the study, if it 
extends through both stages.   
This type of design has greater statistical power than a single-arm design. For example, a single 
arm trial enrolling the same number of subjects (n=39) would only have a statistical power of 
82%, versus 90% for the proposed design. Alternatively, it would require 50 evaluable subjects in 
a single-arm design to achieve the desired 90% power. 
 
9.6. 
Primary Analysis 
Primary analysis for this study will occur after all subjects have either completed the study or 
completed 12 months of treatment. Subjects who are still active at the time of the primary 
analysis may continue on study until disease progression or medication intolerance is observed.

MONITORING, RECORDING, AND REPORTING OF ADVERSE EVENTS  
10.1. 
Toxicities of Nab-Sirolimus 
Nab-Sirolimus is a formulation of rapamycin. No unexpected toxicities not already known for 
rapamycin (Rapamune®) or the rapamycin prodrug, temsirolimus (Torisel®), were identified in the 
nonclinical toxicity studies, or observed in the phase 1 studies for nab-Sirolimus. 
More details on the known precautions, warnings, and AEs of rapamycin and rapalogs are found 
in the Rapamune® and Torisel® Package Inserts.45,46 
10.2. 
Toxicities of Pazopanib 
Per the Prescribing information, the most common AEs in subjects with advanced STS (greater 
than or equal to 20%) are fatigue, diarrhea, nausea, decreased weight, hypertension, decreased 
appetite, hair color changes, vomiting, tumor pain, dysgeusia, headache, musculoskeletal pain, 
myalgia, gastrointestinal pain, and dyspnea.52 
10.3. 
Evaluation of Adverse Events  
The investigator must assign the following AE attributes: 
• AE diagnosis or syndrome(s), if known (if not known, signs or symptoms) 
• Dates of onset and resolution (if resolved) 
• Severity [and/or toxicity per protocol] 
• Assessment of relatedness to the IP 
• Assessment of relatedness to protocol-required procedures  
• Action taken 
The AE toxicity grading scale used will be the NCI CTCAE Version 5.0.  
10.4. 
Serious Adverse Events 
10.4.1. 
Definition of Serious Adverse Events 
An SAE is defined as an AE that meets at least 1 of the following serious criteria: 
• fatal 
• life-threatening (places the subject at immediate risk of death) 
• requires in-patient hospitalization or prolongation of existing hospitalization 
• results in persistent or significant disability/incapacity 
• congenital anomaly/birth defect 
• other medically important serious event 
An AE would meet the criterion of “requires hospitalization”, if the event necessitated an in-
patient admission to a health care facility (e.g., overnight stay).   

Nab-Sirolimus/Pazopanib 
Protocol: CC10015                                                    
University of Washington 
Confidential and Proprietary 
67 
Final Protocol v5.0: July 28, 2022 
If an investigator considers an event to be clinically important, but it does not meet any of the 
serious criteria, the event could be classified as an SAE under the criterion of “other medically 
important serious event”.  Examples of such events could include allergic bronchospasm, 
convulsions, blood dyscrasias, drug-induced liver injury, or events that necessitate an emergency 
room visit, outpatient surgery, or urgent intervention. 
Since the criteria for the CTCAE grading scale differs from the regulatory criteria for SAEs, if AEs 
correspond to grade 4 “life threatening” CTCAE grading scale criteria (e.g., laboratory 
abnormality reported as grade 4 without manifestation of life-threatening status), it will be left 
to the investigator’s judgment to also report these abnormalities as SAEs. For any AE that applies 
to this situation, comprehensive documentation of the event’s severity status must be recorded 
in the subject’s medical record.   
10.4.2. 
Reporting Procedures for Serious Adverse Events 
All SAEs that are drug-related and unexpected must be reported by the Sponsor-Investigator to 
their IRB in writing, and to the FDA within 15 days as required by law. 
Any AE that meets any criterion for an SAE requires the completion of an SAE Report Form in 
addition to being recorded on the AE page/screen of the CRF.  All SAEs must be reported to Aadi 
Bioscience Drug Safety within 24 hours of the Sponsor-Investigator’s knowledge of the event by 
facsimile, or other appropriate method, using the SAE Report Form, or approved equivalent form. 
This instruction pertains to initial SAE reports as well as any follow-up reports. 
The Sponsor-Investigator or treating investigator is required to ensure that the data on these 
forms is accurate and consistent. This requirement applies to all SAEs (regardless of relationship 
to IP) that occur during the study (from the time of signing of the informed consent form to 30 
days after the last dose of IP), and those made known to the investigator at any time thereafter 
that are suspected of being related to IP.   
The SAE report should provide a detailed description of the SAE and include a concise summary 
of hospital records and other relevant documents. If a subject died and an autopsy has been 
performed, copies of the autopsy report and death certificate are to be sent to Aadi Bioscience 
Drug Safety as soon as these become available. Any follow-up data will be detailed in a 
subsequent SAE Report Form, or approved equivalent form, and sent to Aadi Bioscience Drug 
Safety.  
Where required by local legislation, the Sponsor-Investigator is responsible for informing the 
IRB/EC of the SAE and providing them with all relevant initial and follow-up information about 
the event. The Sponsor-Investigator must keep copies of all SAE information on file including 
correspondence with Aadi Bioscience and the IRB/EC. 
10.5. 
Pregnancy and Breastfeeding Reporting 
If a pregnancy occurs in a female subject, or female partner of a male subject, while the subject 
is taking protocol-required therapies, report the pregnancy to Aadi Bioscience as specified below. 
In addition to reporting any pregnancies occurring during the study, investigators should monitor 
for pregnancies that occur up to 3 months after the last dose of protocol-required therapies.

The investigator will follow the female subject until completion of the pregnancy, and must notify 
Aadi Bioscience Drug Safety immediately about the outcome of the pregnancy (either normal or 
abnormal outcome) using the Pregnancy Follow-up Report Form, or approved equivalent form, 
if the female subject consents to allow the study team to follow the pregnancy to completion or 
termination.  
If a lactation case occurs while the female subject is taking protocol-required therapies, report 
the lactation case to Aadi Bioscience as specified below. In addition to reporting a lactation case

REGULATORY OBLIGATIONS 
12.1. 
Informed Consent 
The Informed Consent Document must be reviewed and approved by the Sponsor-Investigator, 
Aadi Biosciences, and the IRB prior to use. Updates to the informed consent document are to be 
communicated to Aadi Bioscience prior to submitting for IRB review and approval. For research 
participants who do not speak and/or read English, a short-form consent should be used. The 
short form is used to document that the elements of informed consent were orally presented to 
the research participant by a qualified interpreter. Both the short form and a written summary, 
which may also be the IRB-approved English-language informed consent document, must be 
submitted filed in the subject chart. 
Before a subject’s participation in the clinical study, the investigator is responsible for obtaining 
written informed consent from the subject after adequate explanation of the aims, methods, 
anticipated benefits, and potential hazards of the study and before any protocol-specific 
screening procedures or the IP is administered.  
The acquisition of informed consent is to be documented in the subject’s medical records, and 
the informed consent form to be signed and personally dated by the subject and by the person 
who conducted the informed consent discussion. The original signed informed consent form is 
to be retained in accordance with institutional policy, and a copy of the signed consent form is to 
be provided to the subject. 
If a potential subject is illiterate or visually impaired, the investigator must provide an impartial 
witness to read the informed consent form to the subject and must allow for questions. 
Thereafter, both the subject and the witness must sign the informed consent form, per 
institutional policy, to attest that informed consent was freely given and understood.   
12.2. 
Institutional Review Board/Independent Ethics Committee  
A copy of the protocol, informed consent form, other written subject information, and any 
proposed advertising material must be submitted to the IRB for written approval. A copy of the 
written approval of the protocol and informed consent form must be received by Aadi Bioscience 
before recruitment of subjects into the study and shipment of Aadi Bioscience IP. 
The Sponsor-Investigator must submit and, where necessary, obtain approval from the IRB for all 
subsequent protocol amendments and changes to the informed consent document.  The 
Sponsor-Investigator is to notify the IRB of reportable deviations from the protocol or SAEs 
occurring at the site and other AE reports received from Aadi Bioscience, in accordance with local 
procedures. 
The Sponsor-Investigator is responsible for obtaining annual IRB approval [IRBs only]/renewal 
[IRBs and IECs] throughout the duration of the study. Copies of the Sponsor-Investigator’s reports 
and the IRB continuance of approval must be sent to Aadi Bioscience.

DATA HANDLING AND RECORDKEEPING 
13.1. 
Data/Documents 
The Sponsor-Investigator must ensure that the records and documents pertaining to the conduct 
of the study and the distribution of the investigational product are complete, accurate, filed, and 
retained. Examples of source documents include: hospital records; clinic and office charts; 
laboratory notes; memoranda; checklists; dispensing records; recorded data from automated 
instruments; copies or transcriptions certified after verification as being accurate copies; 
microfiche; x-ray film and reports; and records kept at the pharmacy; and the laboratories, as 
well as copies of CRFs or CD-ROM. 
13.2. 
Data Management 
Data will be collected via CRF and entered into the clinical database. These data will be 
electronically verified through use of programmed edit checks specified by the clinical team. 
Discrepancies in the data will be brought to the attention of the clinical team, and investigational 
site personnel, if necessary. Resolutions to these issues will be reflected in the database. An audit 
trail within the system will track all changes made to the data. 
13.3. 
Responsibilities for Data Collection 
The Sponsor-Investigator is responsible for complying with the requirements for all assessments 
and data collection (including subjects not receiving protocol-required therapies) as stipulated in 
the protocol for each subject in the study. For subjects who withdraw prior to completion of all 
protocol-required visits and are unable or unwilling to continue the Schedule of Assessments (in 
Table 3, the investigator can search publicly available records (where permitted) to ascertain 
survival status.  
This ensures that the data set(s) produced as an outcome of the study is/are as comprehensive 
as possible. 
13.4. 
Sample Storage and Destruction 
Any blood or tumor sample collected can be analyzed for any of the tests outlined in the protocol 
and for any tests necessary to minimize risks to study subjects. This includes testing to ensure 
analytical methods produce reliable and valid data throughout the course of the study. This can 
also include, but is not limited to, investigation of unexpected results, incurred sample reanalysis, 
and analyses for method transfer and comparability.  
All samples and associated results will be no less than single coded prior to being shipped from 
the site for analysis, or storage. Tracking of samples will be independent of the subject’s 
identification number for the study. Results are stored in a secure database to ensure 
confidentiality.   
Results from this analysis are to be documented and maintained but are not necessarily reported 
as part of this study.  
The records should be retained by the Sponsor-Investigator according to ICH, local regulations,

ICH region or after at least 2 years have elapsed since formal discontinuation of clinical 
development of nab-Sirolimus. 
Since the evaluations are not expected to benefit the subject directly or to alter the treatment 
course, the results of other exploratory studies are not placed in the subject’s medical record and 
are not to be made available to the subject, members of the family, the personal physician, or 
other third parties, except as specified in the informed consent. 
The subject retains the right to request that the sample material be destroyed by contacting the 
Sponsor-Investigator.  Following the request from the subject, the Sponsor-Investigator is to 
provide the sponsor with the required study and subject number so that any remaining blood or 
tumor samples and any other components from the cells can be located and destroyed. Samples 
will be destroyed once all protocol-defined procedures are completed.   
The Sponsor-Investigator is the exclusive owner of any data, discoveries, or derivative materials 
from the sample materials and is responsible for the destruction of the sample(s) at the request 
of the subject, at the end of the storage period, or as appropriate (e.g., the scientific rationale for 
experimentation with a certain sample type no longer justifies keeping the sample). The subject 
has no commercial rights to such product and has no commercial rights to the data, information, 
discoveries, or derivative materials gained or produced from the sample.

QUALITY CONTROL AND QUALITY ASSURANCE 
14.1. 
Study Monitoring 
Institutional support of trial monitoring will be in accordance with the FHCC/University of 
Washington Cancer Consortium Institutional Data and Safety Monitoring Plan. Under the 
provisions of this plan, FHCC Clinical Research Support (CRS) coordinates data and compliance 
monitoring conducted by consultants, contract research organizations, or FHCC employees 
unaffiliated with the conduct of the study. Independent monitoring visits occur at specified 
intervals determined by the assessed risk level of the study and the findings of previous visits per 
the institutional DSMP.  
In addition, protocols are reviewed at least annually and as needed by the Consortium Data and 
Safety Monitoring Committee (DSMC), FHCC Scientific Review Committee (SRC) and the 
FHCC/University of Washington Cancer Consortium Institutional Review Board (IRB). The review 
committees evaluate accrual, adverse events, stopping rules, and adherence to the applicable 
data and safety monitoring plan for studies actively enrolling or treating subjects. The IRB reviews 
the study progress and safety information to assess continued acceptability of the risk-benefit 
ratio for human subjects. Approval of committees as applicable is necessary to continue the 
study.  
The trial will comply with the standard guidelines set forth by these regulatory committees and 
other institutional, state and federal guidelines. 
 
14.2. 
Audits and Inspections 
In accordance with ICH GCP and the sponsor’s audit plans, this study may be selected for audit 
by representatives from Aadi Bioscience’s Inspection of site facilities (e.g., pharmacy, protocol-
required therapy storage areas, laboratories) and review of study-related records will occur to 
evaluate the study conduct and compliance with the protocol, ICH GCP, and applicable regulatory 
requirements.

APPENDIX 1 - WOMEN OF CHILDBEARING POTENTIAL DEFINITIONS 
AND METHODS OF CONTRACEPTION 
17.1. 
Definitions 
17.1.1. 
Woman of Childbearing Potential (WOCBP) 
 
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile. Permanent sterilization methods include hysterectomy, bilateral 
salpingectomy, and bilateral oophorectomy. 
 
Women in the following categories are not considered WOCBP 
 
• Premenarchal 
• Premenopausal female with 1 of the following: 
o Documented hysterectomy 
o Documented bilateral salpingectomy 
o Documented bilateral oophorectomy 
Note: Documentation can come from the site personnel’s review of the 
participant’s medical records, medical examination, or medical history interview. 
• Postmenopausal female 
o A postmenopausal state is defined as 12 months of amenorrhea in a woman over 
age 45 years in the absence of other biological or physiological causes.  
17.2. 
Contraception Guidance for Females of Childbearing Potential 
 
One of the highly effective methods of contraception listed below is required during study 
duration and until the end of relevant systemic exposure, defined as 3 months after last 
treatment. Local laws and regulations may require use of alternative and/or additional 
contraception methods. 
 
Highly Effective Contraceptive Methods That Are User Dependent 
Failure rate of < 1% per year when used consistently and correctly.a 
• Combined (estrogen- and progestogen-containing) hormonal contraception associated 
with inhibition of ovulation 
o oral 
o intravaginal 
o transdermal 
• Progestogen-only hormonal contraception associated with inhibition of ovulation 
o oral 
o injectable 
 
Highly Effective Methods That are User Independent 
• Implantable progestogen-only hormonal contraception associated with inhibition of 

Nab-Sirolimus/Pazopanib

81 
Final Protocol v5.0: July 28, 2022 
Ovulation  
• Intrauterine device (IUD) 
• Intrauterine hormone-releasing system (IUS) 
• Bilateral tubal occlusion 
• Vasectomized partner 
• Sexual abstinence Sexual abstinence is considered a highly effective method only if 
defined as refraining from heterosexual intercourse during the entire period of risk 
associated with the study treatment. The reliability of sexual abstinence needs to be 
evaluated in related to the duration of the study and the preferred and usual lifestyle of 
the participant. 
o It is not necessary to use any other method of contraception when complete 
abstinence is elected. 
• WOCBP participants who choose complete abstinence must continue to have pregnancy 
tests as specified in study calendar. 
• Acceptable alternate methods of highly effective contraception must be discussed in the 
event that the WOCBP participants chooses to forego complete abstinence. 
 
a Typical use failure rates may differ from those when used consistently and correctly. Use 
should be consistent with local regulations regarding the use of contraceptive methods for 
participants participating in clinical studies. 
 
Less Than Highly Effective Contraceptive Methods That are User Dependent 
 
Failure rate of > 1% per year when used consistently and correctly. 
• Male or female condom with or without spermicide. Male and female condoms cannot 
be used simultaneously. 
• Diaphragm with spermicide 
• Cervical cap with spermicide 
• Vaginal sponge with spermicide 
• Progestogen-only oral hormonal contraception, where inhibition of ovulation is not the 
primary mechanism of action 
 
Unacceptable Methods of Contraception 
• Periodic abstinence (calendar, symptothermal, post-ovulation methods) 
• Withdrawal (coitus interruptus) 
• Spermicide only 
• Lactation amenorrhea method (LAM)

17.3. 
Contraception Guidance for Males of Childbearing Potential 
 
Male participants with female partners of childbearing potential are eligible to participate if 
they agree to the following during the treatment and until the end of relevant systemic 
exposure. 
 
• Inform any and all partner(s) of their participation in a clinical drug study and the need 
to comply with contraception instructions as directed by the investigator. 
 
• Male participants are required to use a condom for study duration and until the end of 
relevant systemic exposure defined as 3 months after last systemic dose. 
 
• Female partners of males participating in the study to consider use of effective methods 
of contraception until the end of relevant systemic exposure, defined as 3 months after 
last systemic dose. 
 
• Male participants with a pregnant or breastfeeding partner must agree to remain 
abstinent from penile vaginal intercourse or use a male condom during each episode of 
penile penetration during the treatment and until 3 months after last systemic dose. 
 
• Refrain from donating sperm for the duration of the study treatment and for 3 months 
after last systemic dose. 
 
• Male participants may experience testicular side effects, such as reduced sperm 
production rates, reduced sperm concentrations, decreased epidydimal weights, 
atrophy and degeneration of the testes with aspermia (no sperm production), 
hypospermia (low or reduced sperm production), and cellular changes in the epididymis 
(a tube within the testes that transports sperm).
