PROTOCOL SYNOPSIS 
Name of sponsor/company: CERULEAN PHARMA AUSTRALIA PTY LTD / 
CERULEAN PHARMA INC (parent company) 
Name of investigational product:  CRLX301 
Title of study: Phase 1/2a Dose-Escalation Study of CRLX301 in Patients with Advanced 
Solid Tumor Malignancies 
Study Number:  CRLX301-101 
Number of study center(s): approximately 7 
Study duration: approximately 3 years   
x Date first patient enrolled: December

Name of investigational product:  CRLX301 
Exploratory Study Objectives 
x To evaluate the pharmacodynamic activity of CRLX301 in the blood and tumor biopsy 
specimens when available from patients  
x To explore possible correlations between clinical response and/or toxicities with 
biomarkers  
x To explore the PK profile of CRLX301 (both the total drug and released docetaxel) in 
urine for both dosing schedules 
x To explore potential factors affecting potential inter- and intra-patient PK variability 
and the preliminary relationship between response and the exposure to total and 
unconjugated docetaxel in plasma and urine 
Methodology:  
Phase 1: Schedule 1 (Q3W) is an, open-label, 1+5 followed by classic 3+3 dose-escalation 
study with enrollment to continue until determination of the MTD/RP2D. Schedule 2 (QW, no 
break or QW, 3 week on/1 week off, depending on enrollment cohort*) is an open-label 3+3 
dose escalation study with enrollment to continue until determination of the MTD /RP2D.  
x For Schedule 1 only, patients were accrued in a step-wise manner into two initial 
cohorts of only 1 patient each. Since the patient in the first cohort of 7.5 mg/m2 did not 
experience a dose limiting toxicity (DLT) in Cycle 1, the protocol allowed proceeding 
to the next cohort level of 15 mg/m2. Starting at cohort 3 for Schedule 1 at 30 mg/m2, a 
minimum of 3 patients will be enrolled in all subsequent cohorts.  
x For Schedule 2, a minimum of 3 patients will be enrolled for all planned cohorts. If a 
patient in any Phase 1 escalation cohort experiences a DLT during the first 3 weeks for 
either schedule, then the cohort will be expanded to sequentially enroll additional 
patients up to a total of 6 who complete 3 weeks of treatment as per assigned Schedule.  
x A DLT is a treatment-emergent adverse event (TEAE) attributed to be at least possibly 
related to the investigational product in the first 3 weeks post-initiation of study drug 
infusion in either schedule and that meets the criteria for DLT as defined in the 
protocol. Enrollment in a Phase 1 dose cohort will be halted immediately when ≥2 
patients within the same cohort experience a DLT during the first 3 weeks. The study 
Safety Review Committee (SRC) will review, at a minimum, the safety data at the end 
of Cycle 1 (3 weeks) for Schedule 1, or Week 3 for Schedule 2, for all cohorts to 
confirm DLTs and to determine if dose escalation should occur and at what dose level.

Name of investigational product:  CRLX301 
The MTD is defined as the highest dose level at which fewer than 2 out of 6 patients 
experiences a DLT during Cycle 1 or the first 3 weeks. 
*NOTE: As of Amendment 9, for patients still receiving treatment in Schedule 2 Cohort 3 
(45mg/m2), and for patients enrolled in Schedule 2 Cohort 4 (54mg/m2), dosing will be on a 
once weekly, 3 week on/1 week off schedule. The dosing schedule for additional Schedule 2 
cohorts will be determined by the SRC. A single MTD/RP2D will be determined for Schedule 
2. See Section 1.8.3:Rationale for Evaluation of QW, 3 week on/1 week off for Schedule 2. 
Phase 2a: Stage 1 of Phase 2a will initiate when either dosing schedule determines the 
MTD/RP2D. For Stage 1, up to 16 patients will be enrolled into an expansion cohort for each 
dosing schedule at RP2D to further explore the safety and PK profile of CRLX301. Stage 2 of 
Phase 2a will initiate when Stage 1 expansion is complete for both dosing schedules. For 
Stage 2, the preferred dosing schedule (i.e., either Schedule 1 or 2) will be used for enrollment 
into additional RP2D expansion cohort of up to 36 patients.  
Number of patients enrolled: Up to 134 
Phase 1: Up to 66 evaluable patients are anticipated to be enrolled in the Phase 1 dose 
escalation cohorts (up to 36 patients in Schedule 1 (Q3W); up to 30 patients in Schedule 2 
(QW, no break or QW, 3 week on/1 week off)). The exact number of patients is dependent on 
the actual patients per cohort and number of cohorts investigated in each dosing schedule.  
Patients who do not complete a minimum of 3 weeks of treatment and do not experience a 
DLT will be replaced. 
Phase 2a: Up to 68 patients will be enrolled in Phase 2a RP2D expansion cohort(s) (up to 32 
patients for Stage 1 and up to 36 patients for Stage 2). 
Diagnosis and main criteria for inclusion: 
Patients must meet the following criteria for inclusion: 
1. Male or female adult patients ≥18 years of age 
2. Diagnosis of histologically or cytologically confirmed, advanced solid tumor 
malignancy: 
a. For Phase 1: that is refractory to standard therapy and/or for whom no further 
standard therapy is available, especially for those for whom taxane 
chemotherapy may be a reasonable therapeutic choice, in the opinion of the 
Investigator.  
b. For Phase 2a: advanced/metastatic tumors considered responsive to taxanes 
c. For prostate cancer patients in Phase 2a: that is castration resistant prostate

in the judgment of the investigator, would make the patient inappropriate for the 
study. 
Investigational product, dosage and mode of administration: CRLX301 patients will 
receive an intravenous infusion of CRLX301 on either Dosing Schedule 1: Day 1 of a 21-day 
cycle (Q3W) or Dosing Schedule 2: weekly dosing (QW, no break or QW, 3 week on/1 week 
off dosing, depending on enrollment Cohort), and will continue the treatment schedule until 
progression of disease or unacceptable toxicity (see Section 6.1: Reasons for Discontinuation 
from Treatment). In Phase 1, the initial dose per patient will be determined by their enrollment 
Cohort and assigned dosing schedule according to the protocol dosing scheme. Phase 2a 
patients will all be dosed at the MTD/RP2D for either dosing schedule in Stage 1 and at the 
preferred dosing schedule at RP2D for Stage 2.  
Duration of Treatment:  Patients will remain on study treatment until they experience 
progression of disease (unless there is evidence of clinical benefit and the investigator believes 
it is in the patient’s best interest to continue the study drug treatment), unacceptable toxicity, 
or other specified reason for discontinuation (Section 6.1: Reasons for Discontinuation from 
Treatment).  
Reference therapy, dosage and mode of administration: 
All patients will receive CRLX301 via an intravenous infusion over approximately 120 
minutes. 
Criteria for evaluation: 
Dose Limiting Toxicities: A DLT is defined as any AE possibly, probably, or definitely 
related to CRLX301 that meets the per protocol criteria for DLT (see Section 3.1.3: Definition 
of Dose-Limiting Toxicity) and occurs at any point during Cycle 1 or the first 3 weeks post-
initiation of study drug infusion. The event must be assessed by the Investigator and Safety 
Medical Monitor and/or Study Director, and be determined to be unrelated to disease 
progression, intercurrent illness, or concomitant medications. All DLTs will be graded 
according to the current version of the National Cancer Institute’s (NCI) Common 
Terminology Criteria for Adverse Events (CTCAE 4.03).  
Safety: Safety variables will include AEs, clinical laboratory parameters, vital signs, and ECG 
parameters.  For each safety parameter, the last assessment made before the first dose of the 
investigational product for each period will be used as the baseline for all analyses of that 
safety parameter.

Plasma and urine samples for (PK) evaluation will be collected from Phase 1 and Phase 2a 
Stage 1 patients during Cycle 1 and from available patients in Cycle 3 and Cycle 6 as per the 
schedule defined in Section 5.13: Pharmacokinetic Sample Collection.  
If Schedule 1 is selected for Phase 2a Stage 2 expansion, patients will have plasma samples 
collected using the same schedule defined in Phase 1 until up to 10 patients have undergone 
PK collection at RP2D during both Cycle 1 and a repeat dose in either Cycle 3 and/or Cycle 6. 
Schedule 2 (QW, no break or QW, 3 week on/1 week off): 
Plasma and urine samples for PK evaluation will be collected from Phase 1 and Phase 2a 
Stage 1 patients during Week 1 and from available patients in Weeks 2 through 8 as per the 
schedule defined in Section 5.13: Pharmacokinetic Sample Collection.  
If Schedule 2 is selected for Phase 2a Stage 2 expansion, patients will have plasma samples 
collected using the same schedule defined in Phase 1 until up to 10 patients have undergone 
PK collection at RP2D during both Week 1 and a repeat dose during Week 4 or Week 7 if the 
QW, no break dosing schedule is selected or during both Week 1 and a repeat dose during 
Week 3 or Week 7 if the QW, 3 week on/1 week off dosing schedule is selected. 
Disease status: Disease status will be evaluated at screening and every 8-9 weeks for both 
dosing schedules while on study treatment (until disease progression) by CT scan, or by 
alternative methodologies consistent with tumor type and reviewed by Medical Monitor. See 
Follow Up for required tumor evaluations in patients who discontinue from study treatment 
for reasons other than progression. 
Tumor marker disease evaluation: Tumor marker data to evaluate disease status are 
collected only if appropriate for tumor-type and if feasible per Investigator discretion.   
Efficacy: Tumor response evaluations will be performed by either following RECIST 
guidelines, version 1.1 or alternative methodologies consistent with tumor type (e.g., PCWG2 
criteria for prostate cancer).  Tumor assessments by imaging methodology should be 
completed every 9 weeks for Schedule 1 and for QW, no break cohorts in Schedule 2. As of 
Amendment 9, tumor assessments by imaging methodology should be completed every 8 
weeks for QW, 3 week on/1 week off cohorts in Schedule 2. At investigator discretion, 
imaging should be repeated 3-4 weeks after a partial or complete response is observed. PSA 
assessment for Phase 2a prostate cancer patients should be done every 3-4 weeks. See Follow 
Up for required tumor evaluations in patients who discontinue from study treatment for 
reasons other than progression.

Additional blood collection for biomarker research:  Additional blood samples will be 
collected from all Phase 2a patients for additional biomarker research. Additionally, remaining 
plasma from PK samples from all patients who agree will be used for additional research for 
the same purposes. 
Additional blood collection for pharmacodynamic research:  In Phase 2a Stage 1 only, 
blood samples will be collected for isolation of circulating tumor cells (CTCs) and for 
mononuclear phagocytic system (MPS) function testing. CTC isolation will explore the utility 
of comparing the integrity of microtubule skeleton in CTCs from pre- and post-treatment 
patient samples as a potential read-out of CRLX301 PD activity. MPS function test will 
explore potential drug clearance in addition to renal and hepatic clearance of the study drug.    
Optional tumor tissue collection for research: Archived tumor tissue and pre- and post-dose 
tumor biopsy will be collected, as available, from all patients who consent to these optional 
collections. The tissue will be used for additional research to include exploration of markers 
for efficacy (e.g. proliferation, apoptosis, and cell cycle) and CRLX301 localization; it may 
also include genetic testing related to the cancer diagnosis for research purposes only, no other 
genetic testing will be performed.  
Discontinuation: Eligible patients who are enrolled into the study will be discontinued from 
study treatment if any of the following occur: 
x Documented radiographic or clinical progression of disease unless there is 
evidence of clinical benefit and the investigator believes it is in the patient’s 
best interest to continue the treatment despite disease progression 
x Grade 4 hypersensitivity/infusion related reaction (may also be discontinued 
for Grade 3; see Table 7) 
x AE with clinically unacceptable toxicities (unless there is evidence of sustained 
therapeutic benefit and the investigator believes it is in the patient’s best 
interest to continue the treatment despite the toxicity) including: 
o unresolved related AE ≥Grade 2 that causes a delay of >21 days to 
initiation of next dose of CRLX301 (both dosing schedules) 
o bilirubin >1.2 ULN, or AST and/or ALT >1.5 × ULN concomitant with 
alkaline phosphatase >2.5 × ULN; if either of these are unresolved for 
>21 days from planned next dose 
o any other clinically unacceptable toxicity (in agreement with the study 
Medical Monitor) 
x Withdrawal of consent

x Subject non-compliance with study schedule 
x Protocol violation (including lack of compliance or excessive deviations with 
study schedule) in agreement with the Sponsor/Medical Monitor and/or Study 
Director 
x Lost to follow-up (after repeated attempts for >30 days have been made to 
contact the patient including letters sent by registered mail) 
x Request for discontinuation by a regulatory agency (i.e. FDA) 
x Investigator decision (in consultation with the Safety Medical Monitor and/or 
Medical Director and the patient) if there are changes in the patient’s medical 
condition and/or intercurrent illness that render the patient unacceptable for 
further treatment. The reason for removal must be documented in the eCRF. 
Follow-up: Once study treatment is discontinued, all patients who are alive and not lost to 
follow-up are to be closely followed for evidence of delayed effects of study drug for 30 days 
from the last dose of study drug.  
For patients who are discontinued from study treatment for reasons other than disease 
progression, they will continue to have tumor evaluation with methodologies consistent with 
tumor type until another anti-cancer treatment is started, progression of disease, death, loss to 
follow up or withdrawal of consent, whichever comes first. Therefore, continued evaluations 
may be possible for some patients after the 30-day post dose visit. 
Statistical Methods 
Phase 1: 
The primary endpoint is the frequency of DLTs for each dosing schedule as a function of 
CRLX301 dose. 
Phase 2a: 
The primary endpoints are: 
x Safety and tolerability, evaluated by the following parameters: 
o Type, frequency and severity of AE(s) 
o Laboratory parameters (hematology and chemistry, especially those 
associated with bone marrow and hepatic function) 
o Vital signs 
o Physical examination 
o 12-lead ECG 
The secondary endpoints are:

Patients who receive any amount of study drug, including those who withdraw prematurely 
from the study, will be included within four analysis populations as specified below:  
Safety Population: The Safety Population will consist of all patients who receive any amount 
of investigational product. 
Pharmacokinetic Analysis Population: The PK Analysis Population will consist of all patients 
who receive at least part of 1 dose of CRLX301, have at least 1 PK sample collected on Cycle 
1 Day 1 or Week 1 Day 1 of the study, and have evaluable PK parameters. 
MTD and/or RP2D Population: The MTD and/or RP2D population will include all patients 
treated at the MTD and/or RP2D for each dosing schedule from both Phase 1 and Phase 2a of 
the study.  
MTD and/or RP2D Efficacy Evaluable Populations: The MTD and/or RP2D evaluable 
population will include all patients treated at the MTD/RP2D for each dosing schedule who 
have had tumor assessment at baseline and undergone at least 1 follow-up tumor assessment 
via imaging or methodologies consistent with specific tumor type. 
 
Schedules 1 and 2 will be analyzed separately. As appropriate analysis for each cohort in 
Phase 1 and for each of the MTD expansion cohorts will be reported separately. For Schedule 
2, a single MTD/RP2D will be determined, but other analyses will be reported separately for 
QW, no break cohorts and QW, 3 week on/1 week off cohorts. 
Descriptive statistics including, mean, median, standard deviation (SD), minimum, and 
maximum values will be presented as appropriate for all cohorts treated.  PK parameters for 
individual patients will be calculated, summary (mean +/- SD, min, max, geometric mean and 
geometric coefficient of variation) of PK parameters for each dose cohort and cycle will be 
calculated and statistical analyses will be computed to evaluate differences between dose 
cohorts and cycles. Tumor response rates will be summarized with their 95% Pearson-Clopper 
confidence intervals. Time to event endpoints will be analyzed by survival analysis methods.

1. Clinic visit window rules: For C1 and C2 no visit windows. For C3 through C7 allowable window for Day 1 visit only is ±1 day; for C4 and C5 allowable 
window for D8 and D15 clinic visits is ±1 day;  as of C7D8 and for all subsequent visits, allowable window is ±2 days. 
2. D22 is the equivalent of pre-dose D1 in the subsequent cycle. 
3. Complete PE of body systems must be performed by the Investigator during pre-study and EOS (includes weight).  Limited PE is performed pre-dose on 
C1D1 and at the end of each cycle (D22).  
4. Height required at pre-study only; repeat weight measurement C1D1 to calculate BSA not necessary if pre-study assessment was ≤3 days prior to C1D1. 
Record weight measurement at each subsequent cycle pre-dose and recalculate BSA only if body weight changes by more than 10% and change is attributed 
to dry weight. 
5. Refer to Section 5.7 for vital sign collection time points. Collect VS C1D1 pre-dose, during infusion at 30 min and 60 min, and end of infusion; post infusion 
at +60 min, +3 hr, and +6 hr (-1 hr); VS for all subsequent cycles D1 at pre-dose, +60 min. post-infusion, D8, D22, and EOS visit. Temperature (T) only at 
pre-dose, +6 hr (-1 hr) post infusion and at EOS visit.  As of Cycle 7 collect vital signs pre-dose and at EOS day of visit only. 
6. ECHO or MUGA performed pre-study only for patients with a known history of cardiac insufficiency and symptomatic in the last 3 months, and only if prior 
ECHO or MUGA not available within 30 days of first dose. 
7. ECG required pre-dose and at +1hr (+30min) after end of infusion. 
8. ECG required in C2 only pre-dose and at +1hr (+30min) after end of infusion.  
9. CT brain scan required to confirm known brain metastases have been stable for ≥ 30 days prior to C1D1. If a patient is asymptomatic at pre-study with no 
history of brain metastases, additional brain scanning for eligibility is not required. 
10. Chemistry, hematology, urinalysis and coagulation panels are referenced in Section 5.11. Assessment do not need to be repeated on C1D1 if assessment was 
≤3 days prior to C1D1. As of Cycle 2 it is permissible to perform pre-dose hematology, chemistry and urinalysis within 24 hours of dosing. 
11. As of Cycle 8 perform hematology, chemistry, urinalysis at the beginning of the cycle only on Day 1 pre-dose. The Day 8 (all three assessments) and Day 15 
(hematology and chemistry only) time points are only performed in Cycles 1-7. 
12. Coagulation within 3 days of first dose only for C1. Not performed in C3 or C6; also performed prior to post-dose biopsy in patients who consent to biopsy 
13. Pregnancy test is performed only at pre-study, prior to C1D1 dosing if needed and at EOS: repeat urine pregnancy test on C1D1 not necessary if pre-study 
assessment was ≤3 days prior to C1D1. Test should be repeated as needed for women of child-bearing potential if suspicion of pregnancy. Positive urine 
pregnancy tests should be confirmed with a serum pregnancy test. 
14. For Phase 1, Phase 2a Stage 1 and for up to 10 patients in Phase 2a Stage 2 plasma PK will be collected in C1, C3 and C6: On D1 pre-dose; after initiation of 
infusion at 30 min (during infusion) and 60 min (during infusion); at end of infusion; and after end of infusion at +30 min, +60 min, +3 hr, and +6 hr (-1 hr). 
Collect on D2; D3; D8, and D15 (C1 only). Collect pre-dose on D1 in C2, C4 & C7. Refer to Section 5.13 for complete details on PK time points and 
allowable windows. 
15. D15 plasma PK collection in C1 only.  
16. For Phase 1 and for Phase 2a Stage 1 urine PK will be collected on D1 in C1, C3 and C6. Collect a 15 mL spot urine sample pre-dose; then collect all urine 
from start of infusion (0 h) through 6 h post-infusion. On D8 collect a15 mL spot urine sample.

17. Blood sample for biomarkers in Phase 2a Stage 1 and Stage 2 only. Collect only in C1 and C3: D1 pre-dose and D2. 
18. CTCs in Phase 2a Stage 1 only. Collect only in C1: D1 pre-dose, 4hrs (-1hr) after end of infusion, 24hrs (+/- 4hrs) after end of infusion (D2) and on D8; and 
in C2: D1 pre-dose, 4hrs (-1hr) after end of infusion and on D8. 
19. MPS function in Phase 2a Stage 1 only. Collect pre-dose in Cycles 1 and 3 only. 
20. Perform the tumor measurement at the end of every third cycle or every 9 weeks (Cycle 3, 6, 9, etc.) within a week prior to D22 (as of D15 +6 days) until the 
patient discontinues study drug treatment due to disease progression. If a complete or partial response per RECIST1.1 criteria or with methodologies 
consistent with tumor type is reported, then repeat evaluation 3-4 weeks later for confirmation, at discretion of investigator. If stable response per 
RECIST1.1 criteria or with methodologies consistent with tumor type is reported, then continue repeat evaluation at end of every third cycle (every 9 
weeks). See Section 5.15.3 for alternative methodologies. Patients in Phase 1 with non-measurable disease will require Investigator and Medical Monitor 
review to determine proper disease staging, if any is required. Bone scans will also be required at each tumor evaluation for CRPC patients enrolled into 
Phase 2a. 
21. Tumor measurement and staging not required at EOS if previous evaluation was less than 22 days prior.  
22. For prostate cancer patients in Phase 2a only: collect PSA pre-study; pre-dose at the start of every cycle starting at Cycle 2; at EOS only if it has been > 14 
days since the last PSA measurement; and during Follow-Up if applicable at the same time tumor evaluation is performed 
23. Collect tumor biopsy only if accessible and feasible to collect and with consent of patient; collect pre-study prior to first dose. Collect post-dose any time 
after 3rd dose completed (C3D1). 
24. Tumor marker data will be collected per Institution guidelines only if appropriate for evaluation of disease for the specific tumor-type and if feasible; repeat 
as per standard of care. 
25. During screening, patients will be provided with Day (-1) oral premedication. Patients will be instructed on when (the night prior to the first CRLX301 
infusion) and how to take these medications by the study staff. On D15 of each cycle, oral premedication will be provided to each patient for the subsequent 
cycle. Refer to Section 5.10.2 for complete details on premedication. NOTE: Site staff will call each patient within 72 hours prior to D(-1) to remind patient 
to take premedication. 
26. NOTE: Prior to initiation of CRLX301 infusion, site will confirm whether patient took premedication regimen the prior evening (D(-1)). If patient did not 
take premedication, CRLX301 infusion will be initiated at discretion of investigator. Each CRLX301 infusion should start as slow as possible with no more 
than 15mL infused over the first 15 minutes. Provided the patient does not experience any infusion related symptoms during these 15 minutes, the rate of 
infusion can be gradually increased to complete the infusion in approximately 120 minutes (inclusive of 50mL flush). Refer to the Pharmacy Manual and 
Section 5.10.3.1 for complete administration instructions. 
NOTE: If hypersensitivity event occurs, collect blood sample for tryptase evaluation within 3 hours of event. If patient is to be retreated collect blood 
sample for tryptase prior to each subsequent infusion. See Table on Clinical Laboratory Test Parameters and Timing 
27. Archived tumor tissue confirmed if available and patient has consented. Preparation of slides and shipment to central lab will not be triggered until sponsor 
advises sites in writing. 
28. Patients who are discontinued from study treatment for reasons other than disease progression will continue to have tumor evaluation by RECIST1.1 or with 
methodologies consistent with tumor type every 8-9 weeks per investigator discretion until another anti-cancer treatment is started, progression of disease, 
death, loss to follow up or withdrawal of consent, whichever comes first. Therefore, continued scans may be possible for some patients after the EOS.  
Prostate cancer patients in Phase 2a only will also have PSA collected at the same time tumor evaluation is repeated.

Abbreviations: BSA = body surface area, CT = computerized tomography, D = Day, Dx = Day ‘x’, ECG = electrocardiogram, EOS = End of Study, hr(s) = 
hour(s), min=minutes, PE = physical examination, PK = Pharmacokinetic, T = temperature, VS = vital sign(s), W = week(s) 
1. Clinic visit window rules: For W1 through W8 no visit windows. As of W9 allowable window for dosing is +/- 1d. 
2. Complete PE must be performed by the Investigator during pre-study and EOS (includes weight). 
3. Limited PE is performed pre-dose on W1 and pre-dose every 3 weeks (W4, W7, etc.). 
4. Height required at pre-study only; not necessary to repeat weight on D1W1 if per-study was ≤3 days prior to W1D1. Record weight measurement at each 
week pre-dose and recalculate BSA only if body weight changes by more than 10% and change is attributed to dry weight. 
5. Refer to Section 5.7 for vital sign collection time points. In W1, W4 and W7: D1 pre-dose, during infusion at 30 min and 60 min; end of infusion; post 
infusion at +60 min, +3 hr and +6 hr (-1 hr). In W2-3 and W5-6: D1 pre-dose and at end of infusion. VS for all subsequent weeks D1 at pre-dose, and EOS 
visit. Temperature (T) is recorded: W1, W4, W7 pre-dose and 6hrs (-1 hr) after end of infusion; W2, W3, W5 & W6 record temperature pre-dose and at end 
of infusion; all subsequent weeks record T pre-dose; and EOS.  
6. As of W8 and for EOS, collect vital signs and temperature pre-dose only (day of visit for EOS).

ECHO or MUGA not available within 30 days of first dose. 
8. ECG required +1hr (+30min) after end of infusion. 
9. CT brain scan required to confirm if brain metastases have been stable for ≥ 30 days prior to W1D1. If a patient is asymptomatic at pre-study with no history 
of brain metastases, additional brain scanning for eligibility is not required. 
10. Chemistry, hematology, urinalysis and coagulation panels are referenced in Section 5.11. It is not necessary to repeat W1D1 assessment if pre-study 
assessment was ≤3 days prior to W1D1. All safety labs must be performed pre-dose for clinic days while on study treatment. As of W2: permissible to 
perform D1 chemistry, hematology and urinalysis within 24 hours of dosing. 
11. Coagulation within 3 days of first dose only in W1.  Not needed for other weeks unless post-dose biopsy performed. 
12. Pregnancy test is performed only at pre-study, prior to W1D1 dosing if needed and at EOS: repeat pregnancy test on W1D1 not necessary if pre-study test 
was ≤3 days prior to W1D1. Test should be repeated as needed for women of child-bearing potential if suspicion of pregnancy. Positive urine pregnancy 
tests should be confirmed with a serum pregnancy test. 
13. For Phase 1, Phase 2a Stage 1 and for up to 10 patients in Phase 2a Stage 2, plasma PK will be collected on the dosing day in weeks 1, 4 & 7: On D1 pre-
dose; after initiation of infusion at 30 min (during infusion) and 60 min (during infusion); at end of infusion; and after end of infusion at +30 min, +60 min, 
+3 hr and +6 hr (-1 hr). Also collect on D2. In Weeks 2, 3, 5 & 6 a pre-dose sample will be collected Refer to Section 5.13 for complete details on PK time 
points.

14. For Phase 1 and for Phase 2a Stage 1 urine PK will be collected on the dosing day in weeks 1, 4 & 7.  Collect a 15 mL spot urine pre-dose; then collect all 
urine from start of infusion (0 h) through 6 h post-infusion. 
15. Collect 15 ml spot urine for PK during week 2, 5, and 8 only pre-dose. 
16. Blood sample for biomarker in Phase 2a Stage 1 and Stage 2 only. During treatment collect only W1 and W4: D1 pre-dose and D2. 
17. Blood for CTC in Phase 2a Stage 1 only. Collect blood for CTC only at Week 1 pre-dose, 4hrs (-1hr) after end of infusion, 24hrs (+/-4hrs) after end of 
infusion (Day 2); Week 2 pre-dose; Week 4 pre-dose and 4hrs (-1hr) after end of infusion; and Week 5 pre-dose. 
18. Collect blood for MPS function test in phase 2a Stage 1 pre-dose only in Week 1 and 4. 
19. Perform the tumor measurement every 9 weeks (+6 days) (W9, W18, etc) until the patient discontinues study drug treatment due to disease progression. If a 
complete or partial response per RECIST 1.1 criteria or with methodologies consistent with tumor type is reported, then repeat evaluation 3-4 weeks later for 
confirmation at discretion of investigator. If stable response per RECIST criteria or with methodologies consistent with tumor type is reported, then continue 
repeat evaluation every 9 weeks. See Section 5.15.3 for alternative methodologies. In Phase 1, patients with non-measurable disease will require Investigator 
and Medical Monitor review to determine proper disease staging, if any is required. Bone scans will be required at each tumor evaluation for CRPC patients 
enrolled into Phase 2a. 
20. EOS tumor measurement and staging is not required if previous evaluation was less than 22 days prior.  
21. For prostate cancer patients only in Phase 2a: collect PSA pre-study; pre-dose at the start of every third week starting at Week 4 (e.g. W4, W7, W10, etc.); at 
EOS only if it has been > 14 days since the last PSA measurement; and during Follow-Up if applicable at the same time tumor evaluation is performed. 
22. Collect tumor biopsy only if accessible and feasible to collect and with consent of patient; collect biopsy pre-study prior to first dose. Collect post-dose

how to take these medications by the study staff. On D1 or D2 (as applicable of given week), oral premedication will be provided to each patient for the 
subsequent week’s dosing event. Refer to Section 5.10.2 for complete details on premedication. NOTE: Site staff will call each patient within 72 hours prior 
to D(-1) to remind patient to take premedication. 
26. NOTE: Prior to initiation of CRLX301 infusion, site will confirm that patient ingested premedication regimen the prior evening (D(-1)). If patient did not 
take premedication, CRLX301 infusion will be initiated at discretion of investigator. Each CRLX301 infusion should start as slow as possible with no more 
than 15mL infused over the first 15 minutes. Provided the patient does not experience any infusion related symptoms during these 15 minutes, the rate of 
infusion can be gradually increased to complete the infusion in approximately 120 minutes, inclusive of the 50mL flush. Refer to the Pharmacy Manual and 
Section 5.10.3.1 for complete administration instructions.

INTRODUCTION 
1.1 
Unmet Clinical Need 
According to the International Agency for Research on Cancer, there were 12.7 
million new cancer cases and 7.6 million cancer deaths in 2008, and the global 
cancer burden is expected to nearly double to 21.4 million cases and 13.15 million 
deaths by 2030.1   The most common cancer worldwide is lung cancer 
contributing nearly 13% of the total number of new cases diagnosed among men 
and women, while among women only breast cancer leads at nearly 23%. The 
highest cancer rate for men and women together diagnosed in 2008 is Denmark, 
followed by Ireland and then Australia with the US having the seventh highest.2  
In Australia an estimated 124,910 new cases of cancer will be diagnosed this year, 
with that number set to rise to 150,000 by 2020. In 2011, more than 43,700 people 
are estimated to have died from cancer making it a leading cause of death and 
accounting for about 3 in 10 deaths in Australia. The most 5 common cancers in 
Australia (excluding non-melanoma skin cancer) are prostate, colorectal, breast, 
melanoma and lung cancer and account for over 60% of all cancers.2  
In the United States, cancer will become the leading cause of death in 16 years, 
surpassing heart disease, according to a new report from the American Society of 
Clinical Oncology. The number of new cancer cases is expected to increase nearly 
45% by 2030, from 1.6 million cases to 2.3 million cases annually. Although 
there is a declining rate of deaths due to cancer and improvements in the 5-year 
survival rates, the overall incidence of cancer remains stable in women and with 
slight decline in men.3   The need to continue to identify cancer therapies 
including use of advanced technologies, to improve survival and control of 
disease remains high as cancer continues to be a major health issue in the United 
States and other countries.   
1.2 
Docetaxel 
The active pharmaceutical ingredient of CRLX301 is docetaxel which is a 
member of the taxane family derived from the European yew tree, Taxus 
baccata.4  Taxanes disrupt the microtubular network required for mitotic and 
interphase cellular functions. Docetaxel is a strong inhibitor of microtubule 
disassembly leading to interference with cell division and cell death by apoptosis.5  
By virtue of its strong inhibition of microtubule disassembly, docetaxel is active 
against a variety of cancers and has been approved to treat several human solid 
tumor malignancies including androgen-independent prostate cancer, non-small 
cell lung cancer (NSCLC), and locally advanced or metastatic breast cancer.6,7 It’s 
marketed under the trade name of Taxotere® (hereafter referred to as commercial 
docetaxel). Unfortunately, the therapeutic response to docetaxel is associated with 
dose-limiting side effects such as myelosuppression, neutropenia, anemia and 
fluid retention.8,9  In addition, the poor aqueous solubility of docetaxel requires 
the incorporation of polysorbate 80 and ethanol in the clinical formulation leading 
to increased toxicities such as hypersensitivity.10

1.3 
CRLX301 and Nanoparticle Delivery of Docetaxel 
CRLX301 is a docetaxel-containing nanoparticle that in preclinical animal models 
demonstrates improvements in efficacy with decreased toxicity over the parent 
drug docetaxel.  The polymeric nanoparticle is comprised of docetaxel conjugated 
to a linear cyclodextrin-PEG copolymer that self-assembles into nanoparticles of 
approximately 10-30 nm in size.  The nanoparticle is designed to have size and 
surface properties that favor increased plasma half-life as well as enhanced drug 
deposition and retention in tumors.  Nanoparticle entry into tumors is thought to 
be primarily via extravasation through disorganized leaky vasculature commonly 
found in tumors.  According to the literature, the enhanced permeability and 
retention (EPR) effect of the leaky vasculature allows the entry of particles of 
<200 nm and the poor lymphatic drainage of many tumors results in increased 
residence time of the nanoparticle drug.11 As a result, preclinical studies have 
demonstrated that CRLX301 exhibits extended plasma stability with prolonged 
circulation time, avoids rapid clearance, and accumulates in tumor tissue possibly 
through the EPR effect. 
Nanoparticle delivery of chemotherapeutic drugs is an active area of research 
holding promise for ameliorating problems of solubility and tolerability while 
improving pharmacokinetics and pharmacodynamics of the active drug.12,13,14  
Furthermore, by improving accumulation and distribution patterns of previously 
toxic drugs, nanoparticles offer the potential for improved combination 
therapy.15,16  Preclinical pharmacokinetic studies in mouse tumor models with 
CRLX301 have demonstrated that nanoparticle delivery of docetaxel results in 
high levels of active drug in the tumor. The majority of CRLX301 in the 
circulation is present as conjugated drug where it is inactive.  Upon tumor uptake, 
the majority of the docetaxel is released as active free drug. Conjugated docetaxel 
remains in the tumor tissue for extended periods of time during which there is a 
sustained release of free docetaxel at the target site resulting in enhanced tumor 
cell death over administration of docetaxel control. The combination of increased 
nanoparticle tumor localization and sustained docetaxel drug release results in an 
up to 10-fold increase in drug accumulation in mouse tumors for at least 72 hours 
post nanoparticle administration when compared to a docetaxel control. 
The same nanoparticle CDP (cyclodextrin-PEG copolymer) backbone that 
constitutes CRLX301 is also the CDP backbone used for CRLX101, a first-in-
class nanoparticle drug conjugate containing the payload of 20(S) camptothecin.  
This drug is currently being evaluated in clinical trials.17,18,19,20

<200 nm and the poor lymphatic drainage of many tumors results in increased 
11
residence time of the nanoparticle drug.1 As a result, preclinical studies have
demonstrated that CRLX301 exhibits extended plasma stability with prolonged 
circulation time, avoids rapid clearance, and accumulates in tumor tissue possibly 
through the EPR effect.
Nanoparticle delivery of chemotherapeutic drugs is an active area of research 
holding promise for ameliorating problems of solubility and tolerability while 
12,13,14
improving pharmacokinetics and pharmacodynamics of the active drug.1
Furthermore, by improving accumulation and distribution patterns of previously 
toxic drugs, nanoparticles offer the potential for improved combination 
15,16
therapy.1
Preclinical pharmacokinetic studies in mouse tumor models with
CRLX301 have demonstrated that nanoparticle delivery of docetaxel results in 
high levels of active drug in the tumor. The majority of CRLX301 in the 
circulation is present as conjugated drug where it is inactive.  Upon tumor uptake,
the majority of the docetaxel is released as active free drug. Conjugated docetaxel 
remains in the tumor tissue for extended periods of time during which there is a 
sustained release of free docetaxel at the target site resulting in enhanced tumor 
cell death over administration of docetaxel control. The combination of increased 
nanoparticle tumor localization and sustained docetaxel drug release results in an 
up to 10-fold increase in drug accumulation in mouse tumors for at least 72 hours
post nanoparticle administration when compared to a docetaxel control.
The same nanoparticle CDP (cyclodextrin-PEG copolymer) backbone that
constitutes CRLX301 is also the CDP backbone used for CRLX101, a first-in-
class nanoparticle drug conjugate containing the payload of 20(S) camptothecin.

Preclinical studies of CRLX301 have demonstrated the ability to enhance tumor 
uptake of docetaxel compared to administration of the docetaxel control alone 
leading to a significant improvement in anti-tumor activity of CRLX301 
compared to delivery of docetaxel control alone in several xenograft models 
representing various tumor types including prostate, lung, melanoma and ovarian 
cancers.  In summary, CRLX301is a promising novel nanoparticle therapy for a 
variety of human cancers and has the potential to transform docetaxel into a more 
efficacious and less toxic therapeutic agent.

Non-Clinical Pharmacokinetics, Pharmacology, Pharmacodynamics and 
Toxicology with CRLX301 
1.4.1 
Summary of non-GLP Studies 
In rodent studies, intravenous (IV) administration of docetaxel results in a 
relatively short half-life in the blood, while IV administration of CRLX301 leads 
to prolonged levels of drug in circulation.  While the majority of drug is contained 
within the nanoparticles in circulation, nanoparticles are able to enter tumor and 
release free drug in the tumor. Mouse pharmacokinetic studies have demonstrated 
sustained levels of drug in tumor.  CRLX301 delivered at the same dose as 
docetaxel results in up to10-fold higher levels of free drug in the tumor.    
The anti-tumor activity of CRLX301 has also been studied in rodent xenograft 
models including triple negative breast carcinoma, prostate, multi-drug resistant 
ovarian cancer, squamous non-small cell lung carcinoma (NSCLC), adeno- 
NSCLC and in a syngeneic melanoma model. In all of the models, CRLX301 was 
either superior or comparable to docetaxel in either median survival, delay of 
tumor progression and/or complete response rate. The improved PK and 
biodistribution properties of CRLX301 translated into significant tumor growth 
delay and survival improvement in multiple xenograft models. See Investigator’s 
Brochure for more details.

Summary of Pharmacokinetics in GLP Studies 
In a dog GLP repeat dose study of CRLX301 at dose levels of 0.25, 0.75 and 1.75 
mg/kg once every 3 weeks for 3 treatments. Blood was collected at the following 
time points post injection: 0, 5, 30 minutes; 1, 4, 8 hours, and 1, 2, 4, 8 and 22 
days and plasma samples were analyzed for levels of released and conjugated 
docetaxel. T1/2 values of released docetaxel ranged from 2.22 to 3.47 hours for the 
0.75 and 1.75 mg/kg groups. Total docetaxel T1/2 ranged from 3.87 to 6.14 hours. 
Released and total docetaxel exposure (area under the plasma concentration time 
curve (AUC) and Cmax) were generally dose proportional between 0.25 and 1.75 
mg/kg of the administered CRLX301. There was no notable change in released 
and total docetaxel exposure following repeated CRLX301 dosing with individual 
AUC accumulation ratios ranging from 0.71 to 1.25 for released docetaxel and 
from 0.95 to 1.23 for total docetaxel. There was no notable sex-related difference 
in released and total docetaxel exposure and conjugated drug was measurable out 
to 48 hours. Released docetaxel-to-total docetaxel AUC values ranged from 0.559 
to 1.07% indicating most of the docetaxel existed in the bound state.

Summary of Pharmacology, Pharmacodynamics and Toxicology in GLP

In repeat dose GLP and non-GLP toxicology studies in dogs and rats, CRLX301 
administration resulted in a dose dependent reduction in reticulocytes, platelets 
and white blood cells by 2 days post dose with recovery by 21 days post dose, 
consistent with the known effects of docetaxel on hematological indices. There 
were no observed adverse effects of CRLX301 on ECG parameters and 
respiratory function up to 1.75 mg/kg/dose in the dog, or on neurologic 
assessment up to 10 mg/kg/dose in the rat. Decreases in food consumption in rats 
and dogs and decreases in body weight and/or body weight gain in rats reflected 
the known effects of docetaxel on the gastrointestinal system (mucosal 
degeneration of duodenum, jejunum, and necrosis of stomach). Decreased size 
and weight of testes was reported in both rat and dog studies and correlated with 
histopathologic evidence of degeneration of seminiferous tubules. Decreased size 
of epididymides was correlated with atrophy and single cell necrosis in both 
species.  Decreased spleen and thymus weights in the rat were correlated with 
lymphoid depletion in these organs. Both species had decreased bone marrow 
hematopoiesis reflecting the effects of docetaxel on rapidly dividing cells. In rats, 
other target organ effects included neuroaxonal degeneration of sciatic nerve, 
increased mitosis in Harderian, lacrimal, pituitary glands and in esophagus, eye, 
and liver, atrophy of mammary gland in males, and lymphoid depletion of 
mandibular and mesenteric lymph nodes. In both dogs and rats, there was 
evidence of single cell necrosis of stomach, tongue, esophagus, and also

Clinical Experience with CRLX301 for the Treatment of Advanced Solid 
Tumor 
As of 26 March 2016, 20 patients have been treated with single agent CRLX301 
in Schedule 1 (Q3W) IV in this first-in-human study. Doses tested include 7.5 
mg/m2 (n=1), 15 mg/m2 (n=1), 30 mg/m2 (n=3), 60 mg/m2 (n=3), 75 mg/m2 (n=6) 
and 90 mg/m2 (n=6). All patients were evaluable for dose limiting toxicities 
(DLTs) and MTDs. Safety data from one additional patient treated on Schedule 2 
Cohort 1 (CRLX301 IV weekly [QW, no break] 25mg/m2) are included in the 
summary of the most common treatment-related AEs (TRAEs) in the paragraph 
below. See Section 1.8.3:Rationale for Evaluation of QW, 3 week on/1 week off 
for Schedule 2 for preliminary safety information from additional subjects 
enrolled in Schedule 2 after the 26 March 2016 data cut-off for the 17 August 
2016 CRLX301 Investigator’s IB. 
The most common TRAEs (all grades) experienced by the 21 subjects treated as 
of 26 March 2016 were (% of subjects): fatigue (76%), infusion-related reaction 
(38%); and decreased appetite, nausea and dysgeusia, each in 33% of subjects. 
The majority of these events were of mild to moderate severity. TRAEs ≥ Grade 3 
were reported for 9 (45%) subjects overall; all subjects were on Schedule 1 
(Q3W). The most common treatment-related events ≥ Grade 3 were infusion-
related reaction and neutropenia, each reported for 3 (14 %) subjects. 
observed in the dogs and skin hyperpigmentation but not hyperplasia was still
present at 1 month recovery. 
A dose response (with respect to either incidence or severity) was found for all of 
the observed effects in both species. 
The majority of the observed toxicity effects of CRLX301 in dogs and rats are 
consistent with published toxicology studies with commercial docetaxel.  Most
importantly, no new or unusual effects were observed with the CDP (cyclodextrin 
based polymer) delivery of docetaxel.  Recovery was noted for all effects except
for skin (dogs), testis and sciatic nerve degeneration – this is also reported for 
commercial docetaxel i.e. the nerve and testis effects do not recover by 1 month

post treatment.  The maximally tolerated dose (MTD) for docetaxel when 
delivered by CRLX301 was approximately 20% higher compared to toxicological 
effects for commercial docetaxel in the literature.

Two DLTs were observed during cycle 1 at the 90mg/m2 dose level in 2 subjects 
(1 DLT each) treated on Schedule 1 (Q3W CRLX301). One subject experienced 
reversible grade 3 elevations in transaminases concomitant with grade 2 bilirubin 
(<3 days duration), and 1 subject experienced grade 4 febrile neutropenia (<3 
days duration).  Per protocol, 90mg/m2 exceeded the MTD, and 75mg/m2 was 
declared as the MTD and selected as the RP2D for CRLX301 when administered 
Q3W (Schedule 1). Common side effects related to docetaxel, such as fluid 
retention, were not observed. No new toxicities have been observed that have not 
been reported for docetaxel.  
All 21 patients enrolled received pre-medication with dexamethasone 20 mg IV 
and one dose each of an anti-histamine and a histamine 2 receptor (H2) antagonist 
(IV or orally) within 30-90 minutes prior to CRLX301 administration. A total of 8 
(38%) patients enrolled in Schedule 1 have experienced hypersensitivity infusion 
reactions (HSRs). Within the cohorts which initiated treatment at a dose <90 
mg/m2, the HSRs were either mild (grade 1; n=1) or moderate (grade 2; n=4), 
with one exception of a Grade 3 event occurring at 75mg/m2.  Within the 90 
mg/m2 cohort, 1 patient experienced a Grade 2 HSR, 1 patient experienced a 
Grade 3 HSR and 1 patient experienced a Grade 4 HSR (the latter event, 
described in detail in the Investigator’s Brochure, did not occur until the dose had 
been reduced to 75mg/m2). Most HSRs occurred at cycle 1 or cycle 2 and within 
the first 15 minutes of administration, similar to docetaxel. Four of the 8 patients 
were re-challenged with study drug at a slower infusion rate and/or with an 
increased premedication regimen; these patients either did not have recurrence of 
HSR or experienced additional episodes of mild to moderate HSR that were 
manageable. Two other patients had their first episode of HSR in later cycles and 
were not re-challenged due to study discontinuation as a result of progressive 
disease. The 2 subjects experiencing ≥ Grade 3 HSRs at the 90 mg/m2 dose level 
were discontinued from study treatment and followed up per protocol.  
Secondary to these HSR events, protocol CRLX301-101 was amended 
(Amendment 7) to incorporate changes in the required premedication regimen 
prior to administration of CRLX301, and to prolong the duration of each 
CRLX301 infusion. 
A total of 7 serious adverse reactions considered at least possibly related to 
CRLX301 were reported for 6 subjects. These included the 2 DLTs described 
above, 3 cases involving infusion-related reactions (HSR), and 1 case involving a 
peripheral sensory neuropathy and peripheral motor neuropathy in a subject with 
multiple confounding factors (including a history of diabetes, gout and 
cardiovascular disease, and concomitant chronic colchicine and dexamethasone at 
the time of participation in CRLX301-101). Please see the latest version of the 
CRLX301 Investigator's Brochure for details on this case and other toxicities 
reported.

In terms of anti-tumor activity of study drug as of 26 March 2016, of 13 subjects 
evaluable for efficacy, stable disease lasting ≥ 3 cycles was observed in 6 patients 
with 2 patients experiencing prolonged stable disease (7 and 17 cycles). A patient 
with B-RAF mutant adenocarcinoma of unknown primary who was resistant to a 
prior B-RAF inhibitor had tumor shrinkage per RECIST and partial metabolic 
response per FDG-PET.   
Dose level 75 mg/m2 Q3W is the standard dose and dosing schedule of 
commercial docetaxel given to patients in multiple indications.22 Given the 
preliminary safety events and anti-tumor activity (tumor shrinkage in 1 patient) 
observed at 75 mg/m2 of CRLX301 treatment, the study continues with expansion 
of 75 mg/m2 Q3W cohort to further explore the safety, tolerability, and 
preliminary anti-tumor activity of CRLX301 at the dose that is equivalent to 
standard dose of commercial docetaxel. 
PK studies of CRLX301 were performed after administration of CRLX301 at 7.5, 
15, 30, 60, 75 and 90 mg/m2 IV x 1 over 1 h every 21 days.  Plasma PK studies of 
total and released docetaxel were performed on cycles 1, 3 and 6.  The PK (as 
measured by Cmax and AUC) of total docetaxel was linear from 7.5 to 90 mg/m2; 
whereas, the PK of released docetaxel was more variable.  There was no 
accumulation of total or released docetaxel from cycle 1 to 6. At the equivalent 
dose of 75 mg/m2, the plasma AUC of total docetaxel after CRLX301 is ~100-
fold greater than for commercial docetaxel. In addition after administration of 
CRLX301 at 75 mg/m2, the plasma AUC of released docetaxel is similar to 
commercial docetaxel; however, most of the measured AUC after CRLX301 is 
associated with exposure from 24-168 h, suggesting slow release in plasma. The 
Cmax of released docetaxel in plasma after CRLX301 was 21-fold lower than for 
commercial docetaxel, which might be associated with a decrease in toxicity with 
CRLX301. Refer to the IB for details about clinical PK 
1.6 
Study Rationale 
The development of CRLX301 is focused on the utility of nanoparticles to 
increase the extended plasma stability of docetaxel with slower clearance and 
prolonged circulation time, to provide effective delivery of docetaxel into tumors 
for prolonged periods, enhancing anti-tumor activity while potentially reducing 
the toxicity observed with traditional taxanes. The development program is 
focused on the demonstration of clinical activity and improved safety of docetaxel 
when administered in this nanoparticle formulation. 
Studies in animals have demonstrated the ability to maintain CRLX301 for 
prolonged periods while sustaining low released docetaxel concentrations in the 
blood optimizing the cell-cycle specific activity associated with continuous low 
drug exposure.  These specific characteristics have demonstrated, in vivo, the 
intended improvement in anti-tumor activity of CRLX301 compared to delivery 
of docetaxel alone.

This study protocol would allow the first-in-human dosing of CRLX301 in 
patients with advanced solid tumor malignancies to evaluate the safety and to 
establish the MTD and/or RP2D of CRLX301 in an optimal dosing schedule. The 
dosing, safety and clinical outcomes data reported from the Phase 1 and Phase 2a 
treated patients may support the future planning of clinical trials to evaluate 
efficacy endpoints for development of CRLX301.  
1.7 
Rationale for Q3W Dosing and the Starting Dose Phase 1 Based on Clinical 
Experience with Docetaxel 
Since a once every-three-week dose (Q3W) schedule is used as the standard 
dosing schedule for commercial docetaxel and the pre-clinical PK study showed 
that half-life of CRLX301 is longer than commercial docetaxel, Cerulean decided 
to evaluate a dosing schedule which is not more frequent than Q3W in this first-
in-human study. Therefore, Q3W dosing schedule was chosen as the initial dosing 
schedule of CRLX301 in this Phase 1 study.   
The recommended starting dose for Schedule 1 Q3W dosing in humans was based 
on the results of the CRLX301 nonclinical repeat dose toxicity studies in dogs, the 
more sensitive species, would be 5.8 mg/m2/dose. However, Cerulean medical 
advisors and clinical trial investigators considered it to be unethical to expose 
patients to a starting dose of less than 10% of the approved dose of docetaxel (75 
mg/m2), an active chemotherapy agent, and that this ratio for starting dose should 
not exceed 50%.  
The toxicological effects of CRLX301 reported in dogs (the more sensitive 
species) are all consistent with docetaxel findings, and are shown to be reversible 
within 3 weeks, with the exception of the testicular and skin effects at the HNSTD 
(1.75 mg/kg or 35 mg/m2). Furthermore, there were no observed adverse effects 
on ECG or respiratory parameters up to 1.75 mg/kg (35 mg/m2) in dogs, or 
adverse effects on neurologic function up to 10 mg/kg (60 mg/m2) in rats.  These 
evidences offer the opportunity for an actual starting dose to be potentially higher 
than the calculated starting dose at 5.8 mg/m2 per dose.  
A recent study reported that the mean ratio of MTD to starting dose and total 
number of required dose levels in clinical Phase 1 studies was significantly 
greater for nanoparticles compared to small molecules when using the usual 
method to determine clinical Phase 1starting dose from preclinical dog study 
results.23 The CRLX301 preclinical results along with the report finding clinical 
Phase 1 studies of nanoparticles start at lower dose levels relative to the clinical 
MTD support using a higher starting dose in a clinical Phase 1 study of docetaxel 
in a nanoparticle.  Accordingly, the starting dose employed in this initial Phase 1 
evaluation of CRLX301 for Schedule 1 was 10% of the approved dose of 
docetaxel (75 mg/m2). This dose is equivalent to 7.5 mg/m2.

1.8 
Rationale for Weekly Dosing (Schedule 2) and the Starting Dose Based on 
Clinical Experience with CRLX301 
1.8.1 
Rationale for Weekly Dosing 
As per Section 1.5: Clinical Experience with CRLX301 for the Treatment of 
Advanced Solid Tumor, no DLT was observed for Q3W dosing in the 6 patients 
treated at dose level 75 mg/m2 which is equivalent to the standard dose of 
commercial docetaxel. At dose levels below 75 mg/m2, CRLX301 was well 
tolerated with minimal toxicity. One exception is the patient receiving chronic use 
of colchicine in the 60 mg/m2 cohort who developed Grade 3 neuropathy (see 
Section 1.5: Clinical Experience with CRLX301 for the Treatment of Advanced 
Solid Tumor and the CRLX301 Investigator’s Brochure for additional details). 
Myelosuppression effect was minimally observed at 30 and 60 mg/m2 dose levels 
while stable disease was observed with 2 patients in each cohort. Based on this 
level of clinical activity and low observed toxicity to date, there is room to 
explore in parallel a more frequent (weekly) dosing schedule. 
PK studies of CRLX301 were performed after administration of CRLX301 at 7.5, 
15, 30, 60 and 75 mg/m2 IV x 1 over 1 h every 21 days.  Plasma PK studies of 
total and released docetaxel were performed on cycles 1, 3 and 6.  After 
CRLX301 infusion, elimination half-lie and total docetaxel in plasma was 
approximately 5 -8 hours and the T1/2 of released docetaxel was approximately 42 
– 121 hours. However, the long estimate of T½ of released docetaxel is related to 
a consistent release of docetaxel from CRLX301 rather than a slower elimination 
of released docetaxel.  The ability to administer CRLX301 on a weekly schedule 
is further supported by the measured concentration versus time profiles of 
CRLX301 at 30, 60 and 75 mg/m2 IV every 21 days.  In that study there was no 
detectable exposure of total docetaxel on day 8 of cycles 1, 3 or 6.  This supports 
the ability to explore weekly dosing. 
There's mounting evidence that higher frequency of treatment with chemotherapy 
agents at lower doses may be more optimal than therapy at higher doses 
administered less frequently.  This is supported by the emerging data from 
evaluation of metronomic chemotherapy.24 A study of weekly paclitaxel in the 
adjuvant treatment of breast cancer compared toxic effects of paclitaxel and 
docetaxel between Q3W and QW schedule and demonstrated that there were 
significantly less adverse events resulted from weekly dosing of docetaxel as 
opposed to Q3W dosing.25 Paclitaxel is currently given to patients with once 
weekly dosing schedule as a common practice. With the NDC technology 
platform, the preclinical study showed that weekly dosing of CRLX301 in mice 
could lead to  up to 10-fold increase in drug accumulation in mouse tumors for at 
least 72 hours post nanoparticle administration when compared to a docetaxel 
control, thus it’s hypothesized that more frequently dosing of CRLX301 would 
lead to more cumulative delivery of NDC conjugated form of docetaxel to tumor 
while potentially associating with less toxicities resulted from released form of 
docetaxel.

dosing. Schedule 2 dose escalation will initiate in parallel with the Schedule 1 
Q3W dose escalation.  
Once enrolled and assigned to either Schedule 1 or Schedule 2 dosing schedule, 
patients will not be allowed to switch dosing schedules during treatment.  
1.8.2 
Rationale for Starting Dose for Schedule 2 during Phase 1 (QW, no break)  
To better calculate the initial starting dose for the QW, no break schedule, we 
have performed two separate PK simulations from the ongoing Q3W schedule.  
Each model was performed to simulate the concentration versus time profiles of 
total and released docetaxel in plasma after administration of CRLX301 at 20, 25, 
30 and 40 mg/m2 administered IV x1 per week for nine consecutive weeks. The 
AUC versus time profiles of total and released docetaxel were estimated for the 
1st, 4th and 7th dose.  These doses are the proposed doses that would be evaluated 
in the phase 1 clinical trial of CRLX301 on the weekly dosing schedule. The PK 
simulations suggest that administration of CRLX301 at 20 to 40 mg/m2 IV x 1 
weekly for 9 weeks will not result in accumulation of total or released docetaxel 
in plasma. The estimated total docetaxel AUCs after the 1st, 4th, and 7th doses of 
CRLX301 at 20 and 40 mg/m2 are approximately 22% and 45% of the AUCs 
achieved after administration of CRLX301 at 75 mg/m2 Q3W. In addition, the 
estimated released docetaxel AUCs after the 1st, 4th, and 7th doses of CRLX301 
at 20 and 40 mg/m2 are approximately 32% and 65% of the AUCs achieved after 
administration of CRLX301 at 75 mg/m2 Q3W. The PK simulation further 
supports weekly dosing schedule as well as a starting dose in the range of 20 to 40 
mg/m2. 
The planned starting dose for Schedule 2 weekly dosing Phase 1 dose escalation 
is 25 mg/m2. This represents 1/3 of the dosing intensity of the MTD/RP2D 
following Q3W dosing.  
Also for Schedule 1, dose level 30 mg/m2 demonstrated to be well tolerated with 
minimal toxicity: 1 patient was on study for 3 cycles; 1 patient was on study for 7 
cycles and 1 patient was on study for 10 cycles. Multi-dose PK data (up to 6 doses 
in 2 patients) at 30 mg/m2 showed no detectable level of either total nor released 
docetaxel after the CRLX301 infusion by Day 8 in each treatment cycle. 
Therefore, 25 mg/m2 is deemed a safe starting dose for Schedule 2, a weekly 
dosing schedule.

1.8.3 
Rationale for Evaluation of QW, 3 week on/1 week off for Schedule 2 
As of 11 November 2016, a total of 12 patients have been enrolled into Schedule 
2 of CRLX301-101 (see Table 2). A review of safety data from Cohort 3 
(45mg/m2 QW) revealed new events of neuropathy in 3 patients after at least 3 
weeks of treatment with CRLX301. The first subject developed Grade 1 
peripheral neuropathy at week 6, which worsened to Grade 2 at week 9, leading to 
dose interruption. A second patient developed Grade 2 peripheral neuropathy at 
week 9, also leading to dose interruption, and a third patient developed Grade 1 
intermittent peripheral sensory neuropathy at week 4. This latter patient also 
reported Grade 2 bilateral episcleritis, which led to dose interruption. 
Based on these data, CRLX301 dosing has been revised from QW, no break to 
QW, 3 week on/1 week off for any patient enrolled into Schedule 2 Cohort 3 and 
continuing on treatment as of 11 November 2016. This change in dosing 
frequency will also apply to all patients enrolled into Schedule 2 Cohort 4 (54 
mg/m2). The dosing schedule for cohorts beyond Cohort 4 will be determined by 
the Safety Review Committee (SRC).

INVESTIGATIONAL PLAN 
3.1 
Phase 1 Dose Escalation Study Design 
3.1.1 
Study Design Summary 
Phase 1 of the study is an open-label, dose-escalation study examining two 
separate dosing schedules. Schedule 1 (Q3W dosing schedule) was initiated first 
and Amendment 6 incorporates Schedule 2 (QW, no break dosing schedule). As 
of Amendment 9, for patients still receiving treatment in Schedule 2 Cohort 3 
(45mg/m2), and for patients enrolled in Schedule 2 Cohort 4 (54mg/m2), dosing 
will be on a once weekly, 3 week on/1 week off schedule. The dosing schedule 
for additional Schedule 2 cohorts will be determined by the SRC. A single 
MTD/RP2D will be determined for Schedule 2. See Section 1.8.3: Rationale for 
Evaluation of QW, 3 week on/1 week off for Schedule 2. 
For Q3W dosing the first 2 cohorts utilized a 1+5 study design.  A single patient 
was enrolled sequentially into cohort 1 and cohort 2. If either patient in cohort 1 
or 2 had experienced a dose limiting toxicity (DLT) during Cycle 1, then the 
cohort would have been expanded to enroll additional patients up to a total of 6.  
Furthermore, if the initial patient in cohort 1 experienced a DLT in Cycle 1, then 
enrollment would have reverted to a 3+3 design for cohort 2.  
 
As of planned cohort 3 for Q3W dosing and for all cohorts in QW dosing, a 3+3 
dose escalation schema will be utilized.26  Initially a minimum of 3 patients will 
be accrued into each cohort. It is permissible to enroll more than 3 patients 
initially to further explore the safety or PK profile of a particular dose level.  If 
any 1 of the initial enrolled patients in a cohort experiences a DLT during Cycle 1 
or the first 3 weeks, then the cohort will be expanded to enroll additional patients 
up to a total of 6.  
Subsequent cohorts will enroll a minimum of 3 patients with dose escalation until 
≥2 patients in a cohort experience DLT(s) during Cycle 1 or the first 3 weeks.  A 
DLT is defined as any adverse event (AE) possibly, probably, or definitely related 
to CRLX301 that results in an unacceptable toxicity (per criteria specified) and 
occurs at any point during Cycle 1 or the first 3 weeks post-initiation of study 
drug infusion.  
Additionally, the Safety Review Committee (SRC) is responsible to determine 
whether or not there is a defined wait period between any or all patients into a 
new cohort.  See Section 3.1.6: Study Safety Review Committee for details. 
Enrollment in a particular dose cohort will be halted immediately when ≥2 
patients within the cohort experience a DLT during Cycle 1 or the first 3 weeks. 
At this point, dose de-escalation will occur until <2 of 6 patients experience a 
DLT in a cohort. Then dose escalation with an additional cohort assigned to a 
mid-way dose level may be required to determine MTD and/or RP2D.

Phase 1 enrollment into both dosing schedules may run in parallel.  Enrollment 
will be managed through close communication with participating clinical sites so 
that Investigators are aware of available patient slots in each of the dosing 
schedules.

3.1.2 
Definition of Maximum Tolerated Dose and Recommended Phase 2a Dose 
The MTD is defined as the highest dose level at which fewer than 2 of 6 patients 
in a Phase 1 dose escalation cohort experiences a DLT during the first three weeks 
of treatment. This is the dose level for which the incidence of DLT is <33%.23 
The RP2D is defined as the dose which will be assigned in Phase 2a as advised by 
the SRC based on AEs, anti-tumor activity of CRLX301 and available PK and PD 
data.  The RP2D may be the same as the MTD dose level or it may be lower.  The 
RP2D may not exceed the MTD.  
3.1.3 
Definition of Dose-Limiting Toxicity 
A DLT is defined as any AE possibly, probably, or definitely related to CRLX301 
that results in an unacceptable toxicity (per criteria below) and occurs at any point 
during the first 3 weeks of treatment post-initiation of study drug infusion. The 
event must be assessed by the Investigator and study Medical Monitor, and be 
determined to be unrelated to disease progression, intercurrent illness, or 
concomitant medications.  All DLTs will be graded according to the current 
version of the Common Terminology Criteria for Adverse Events (CTCAE 
Version 4.03) (Appendix B).

o Grade 3 anorexia 
o Grade 3 dehydration as a result of nausea and vomiting 
o Grade 3 constipation 
o Grade 3-4 hypersensitivity/infusion reaction 
o Grade 3 electrolyte disturbance resolving to ≤ Grade 1 or baseline 
within 7 days (supplementation allowed) 
x Any ≥ Grade 2 peripheral neuropathy > 14 days  
x Any unresolved related AE that results in >21day delay to initiate the patient’s 
second dose, excluding alopecia 
x Any other ≥Grade 2 toxicity of any duration that in the opinion of the 
Investigator and upon review with the Medical Monitor is determined to be a 
clinically unacceptable risk. 
3.1.4 
Treatment Schedule 
Eligible patients will receive an intravenous infusion of CRLX301 on: 
x Schedule 1 (Q3W): Day 1 of a 21-day cycle

CONFIDENTIAL 
x Schedule 2 (QW): Day 1 of every week, no break or QW, 3 week on/1 
week off * (depending on enrollment cohort) 
and continue treatment as per assigned Schedule until progression of disease 
(unless the Investigator and sponsor agree it is acceptable for the patient to 
continue treatment) or other specified reason for study discontinuation (see 
Section 6.1: Reasons for Discontinuation from Treatment).   
*For Schedule 2 (QW, 3 week on/1 week off), CRLX301 will be dosed weekly 
for the first 3 weeks of each 4-week period (e.g., week 1, week 2, week 3). No 
CRLX301 will be administered on week 4.  
3.1.5 
Phase 1 Dosing Cohorts 
Schedule 1 
Sequentially enrolled cohorts will receive increasing doses of CRLX301 in Cycle 
1 until ≥2 patients experience DLTs.  Eligible patients will be assigned to the 
currently open cohorts and assigned to the specified dose of CRLX301 per Table 
1: Schedule 1 Q3W Provisional Phase 1 Dose Escalation Scheme.  After halting 
dose escalation due to DLTs, dose de-escalation will occur until <2 patients out of 
6 experiences a DLT in a cohort.  
For determination of the MTD, an additional cohort may be enrolled and assigned 
to the dose level midway between the dose level at which <2 patients out of 6 
experiences DLTs and the dose level at which ≥2 patients out of 6 experiences 
DLT. 
The Schedule 1 Cohort 1 starting dose level was 7.5 mg/m2; see Section 1.7: 
Rationale for Q3W Dosing and the Starting Dose Phase 1 Based on Clinical 
Experience with Docetaxel. The initial dose level was increased by 2 times to 15 
mg/m2 dose-level; thereafter, the dose level increments will be an additional 15 
mg/m2.   
Schedule 2 
The Schedule 2 Cohort 1 starting dose level is 25 mg/m2, see Section 1.7: 
Rationale for Weekly Dosing (Schedule 2) and the Starting Dose Based on 
Clinical Experience with CRLX301.  
3.1.5.1 
Cohort Expansion for DLT 
If at any time during the first three weeks of treatment on either Schedule a 
patient experiences a DLT, then additional patients will be enrolled up to a total 
of 6 treated at the same dose level. Upon expansion, the SRC will decide if 
enrollment between each additional patient will require a defined wait period or if 
additional patients may enroll as soon as eligible.  If at any time during the first 
three weeks of treatment a second patient experiences a DLT then enrollment in 
that cohort will be halted immediately.

If none of the additional patients enrolled in the same cohort experiences a DLT 
in the first three weeks of treatment (i.e., <2 out of 6 patients in the cohort), then 
dose escalation may occur with enrollment of new patients at the next dose level 
per the Dose Escalation Scheme.  
3.1.5.2 
Cohort Dose Escalation Scheme 
Before a decision is made to increase the dose a minimum of 1 patient (Schedule 
1 Cohort 1 and 2 only) and a minimum of 3 patients (all subsequent Cohorts for 
Schedule 1 and for Schedule 2) must have been treated with the assigned dose of 
CRLX301 and have completed three weeks of treatment.  For Schedule 1 this 
includes the Day 22 safety evaluation (21 days post-infusion) and for Schedule 2 
this includes pre-dose or day of visit evaluations for Week 4.  The SRC will 
review emerging safety data from the current cohort and data from on-going 
patients in previous cohorts before proceeding to enrollment in the subsequent 
cohort.  Each dosing schedule will be reviewed independently.  
Cohort dose escalation will follow the Dose Escalation Scheme tables (Table 1 
and Table 2).   
x If in Cohort 1, there are 2 patients who experience a DLT during the first 
three weeks of treatment, dose escalation will not occur.  Subsequent 
cohorts may be dosed at a lower dose and/or at a less frequent schedule to 
be determined by the Sponsor, Medical Monitor, and Investigators and 
implemented per protocol amendment. 
x If in Cohort 1 there is no more than 1 patient who experiences a DLT 
during the first three weeks of treatment, then dose escalation will occur.  
x Similarly, for subsequent Cohort dose levels, if no more than 1 of up to 6 
patients in the cohort experiences a DLT during the first three weeks of 
treatment, then dose escalation will occur with enrollment of new patients 
at the next dose level per the Dose Escalation Scheme.  
Intermediate dose level cohorts are allowed as recommended by the SRC instead 
of escalating to the next planned dose cohort. 
In the absence of DLT if the SRC or sponsor wants to further define the safety, 
efficacy, PK or PD profile of CRLX301 at a particular dose level, additional 
patients may be enrolled at the same, intermediate or lower dose levels following 
consultation between the investigator and sponsor. 
Additionally, and for Schedule 1 only, based upon review of AEs and available 
PK data by SRC at the end-of cohort-review-meeting for the 30 mg/m2 cohort, 
100% dose escalation from 30 mg/m2 to as high as 60 mg/m2 (80% of the 
approved dose of docetaxel) for the next cohort was allowed if recommended by 
the SRC. No other planned cohorts may be skipped during Schedule 1 Phase 1 
dose escalation.

For Schedule 2 only, based upon review of AEs and available PK data by SRC at 
the end-of cohort-review-meeting it is allowable to skip a proposed dose level in

However, dose increment to the next higher dose level shall not exceed 40% at 
dose levels below 50 mg/m2 and will not exceed 20% at dose levels at or above 
50 mg/m2.

Phase 1 Meetings: This committee will discuss all DLTs, AEs, PK parameters if 
available, and other relevant data on regular teleconferences, no less frequently 
than after completion of enrollment and treatment in a cohort prior to dose 
escalation. 
Phase 1 Decision-making role: The SRC is designated to make decisions for the 
Study for each dosing schedule regarding: 
x confirmation of DLTs 
x confirmation to proceed with enrollment in a new cohort with dose 
escalation 
x confirmation of next dose level 
x determine if any type of enrollment wait period will be imposed between 
patients in the next cohort or during expansion (based on emerging safety 
data) 
x recommend if dose schedule modifications are needed according to the 
clinical and PK data available 
x determination of the MTD and/or RP2D. 
In the event the SRC is not in agreement, then the Sponsor Chief Medical Officer 
will make the final decision after consultation with additional medical advisors.

3.1.7 
Dose Reductions 
Patients experiencing a DLT in first 3 weeks will have the study drug interrupted 
and will be followed until recovery from their DLT to grade ≤1 or baseline. After 
that, if the investigator (along with the Sponsor) concludes that it is in the 
patient’s best interest to resume study treatment, the patient may continue in the 
study at a lower dose level. 
Patients who do not experience a DLT but are dosed in the same cohort where ≥2 
patients experienced DLTs, will be dose de-escalated to the next lower already 
studied dose level at the next scheduled treatment, as per the Dose Escalation 
Scheme.  
3.1.7.1 
Dose De-escalation 
If during later treatment beyond the DLT period, a patient experiences an 
unacceptable toxicity (defined as a toxicity that meets the same criteria of DLT 
for the first 3 weeks), the patient may continue in the next treatment cycle but 
must have a dose reduction to the next lower dose level as per the Dose 
Modification Scheme.  
A maximum of 2 dose de-escalations will be permitted per patient. Patients 
who require >2 dose reductions will be discontinued from treatment and will be 
followed up per protocol.  
3.2 
Phase 2a Expansion Study Design 
Phase 2a will be an open-label RP2D expansion study. Treatment guidelines for 
the RP2D expansion cohorts will be the same as those for the Phase 1 dose 
expansion cohorts.  
Patients will be followed for safety, tumor response, and progression free survival 
(PFS) while on the study per RECIST version 1.1 guidelines or with 
methodologies consistent with tumor type.  Patients will remain on study 
treatment until they experience progression of disease unless the Investigator feels 
the patient would benefit from continued treatment, unacceptable toxicity, or 
other specified reason for discontinuation (see Section 6.1: Reasons for 
Discontinuation from Treatment).

3.2.1 
Phase 2a Stage 1 Expansion 
Once either of the dosing schedules confirms MTD from Phase 1 and the sponsor 
confirms that all required pharmacodynamic assays are ready, Phase 2a Stage 1 
will initiate. This will be an expansion of up to 16 patients for each dose schedule 
at the RP2D. Up to 5 specific tumor types will be selected and only patients with 
the select tumor types may enroll into Phase 2a Stage 1. At the time of 
Amendment 8, taxane naïve (unless approved by Sponsor) castration resistant 
prostate cancer (CRPC) has been selected as one of the indications for Ph2a Stage 
1. Enrollment cap will be contingent upon enrolling at least 6 patients of the same 
indication (e.g. CRPC who are taxane naïve) and observation rates of anti-tumor 
activity. All sites will be notified of the select tumor type(s) in advance of 
initiating Stage 1. Due to shipping and processing requirements for CTCs and 
MPS function (both of which require freshly collected whole blood samples) only 
US sites will enroll patients in Stage 1.  
3.2.2 
Phase 2a Stage 2 Expansion 
Once both dosing schedules complete Phase 2a Stage 1 an optimal dosing 
schedule will be selected based on available safety and efficacy signals, PK and 
available PD data from both schedules. Further refinement of the RP2D may also 
be explored. Phase 2a Stage 2 expansion will enroll up to 36 additional patients 
using one selected dosing schedule and RP2D. Up to 5 specific tumor types only 
will be allowed to enroll into Phase 2a Stage 2. Sites in both Australia and US 
will enroll into Stage 2. All sites will be notified of the select tumor types in 
advance of initiating Stage 2.

STUDY PROCEDURES 
See Schedule of Procedures. 
5.1 
Informed Consent and HIPAA 
Written informed consent, and HIPAA authorization (United States only) to use 
or disclose protected health information, must be obtained from a prospective 
patient before any study-specific procedures are performed for that individual.  
Standard of care assessments performed before informed consent is obtained may 
be utilized to screen for study eligibility.  Patients will read the Informed Consent 
Form (ICF), and the HIPAA authorization (as applicable), after being given an 
explanation of the study.  Before signing the ICF and HIPAA authorization form, 
patients will have an opportunity to discuss the contents of the ICF and HIPAA 
form with study center staff.  Patients will be made aware that they may withdraw 
from the study at any time.  Patients who agree to participate in the study will sign 
the most recently approved ICF and the HIPAA authorization form and will be 
provided with a copy of the fully executed documents.  The original, executed 
ICF and HIPAA will be maintained in the respective patient’s clinical study file. . 
Refer to Section 12: Ethical Considerations 
Once screening procedures have begun, patients will be provided with Day(-1) 
premedication along with instructions to be followed once eligibility is confirmed.  
NOTE: Research staff will call each patient within 72 hours prior to Day(-1) to 
remind the patient to take premedication. 
 
5.2 
Eligibility, Study Enrollment, and Patient Number Assignment 
Patients will be assigned screening numbers consecutively by the Investigator or 
designee at the time the patient signs the ICF. For all patients screened, the 
Investigator or designee will record the eligibility criteria assessment in the 
medical record.  A screening and enrollment log will capture screening number, 
date of enrollment or determination as ineligible, and the assigned subject 
enrollment number, if enrolled. 
Enrollment for this study is defined as any patient that has received at least one 
dose of CRLX301.   
Each eligible, enrolled patient in the study will be uniquely identified by a patient 
identification number.   Patients will be assigned a study number by the Sponsor 
only after screening eligibility is confirmed (repeat assessments being performed 
within 3 days of first dose may still be pending).  Once assigned, a patient 
identification number will not be reused.   
See the Investigator Site File for Enrollment forms and complete enrollment 
instructions. The Sponsor and Medical Monitor may review eligibility and have 
final determination regarding whether a patient is eligible as appropriate.

5.6 
Physical Examination and BSA 
Patients will undergo a complete physical examination, which will be completed 
by the investigator who is a professionally trained physician or health professional 
listed on Form FDA 1572 and licensed to perform physical examinations, pre-
study and at the End-of-Study visit.  Complete physical examination will include 
the major body systems, including skin, height (pre-Study only), weight, and 
ECOG Performance Status (Appendix A).   
In addition, a limited physical examination will occur every three weeks (end of 
each cycle for Schedule 1 or pre-dose every 3 weeks for Schedule 2 – QW, no 
break) or every four weeks (pre-dose every 4 weeks for Schedule 2 – QW, 3 week 
on/1 week off).  Limited physical examinations will include general appearance, 
heart, lungs, abdomen, and any symptom directed examination of body/system 
organ(s).  Symptom directed exams will require the patient to report on any 
signs/symptoms that they may have and, based on the patient’s report, the 
Investigator will conduct physical examinations of relevant body/system organ(s). 
Height and weight will be used to calculate Body Surface Area (BSA). BSA will 
be calculated for the first dosing day and recalculated only if body weight changes 
by more than 10% and the change is attributed to dry weight. (Section 7.2.1: Body 
surface Area Calculation.) 
5.7 
Vital Signs 
Vital signs measurement includes diastolic and systolic blood pressure (BP), heart 
rate (HR), and respiratory rate (RR).  These will be assessed by study center staff 
as per the time points in the Schedule of Procedures and/or Table 3 and Table 4. 
BP and HR will be measured with patients in the sitting or supine position 
(patients must be sitting or supine for at least 5 minutes), using the same arm 
throughout the study, and before any corresponding blood sample is collected.  
All vital sign assessments will be recorded on the eCRF, including any additional 
assessments completed for evaluation of potential infusion reactions or possible 
AEs.

 Electrocardiogram 
Standard 12-lead ECG will be performed for safety as per the time points in the 
Schedule of Procedures.  The paper speed will be a standard 25 mm/second; the 
ECG tracing will be kept at the study center.  Measurements will be recorded for 
the following parameters in lead II or lead III: heart rate, PR interval, QRS 
duration, QT interval, and QTc (using the Fredericia method of QTc analysis). If 
any reading is abnormal, then the ECG will be repeated in triplicate and the 
average value of the 3 readings will be reported. 
ECGs will be clinically interpreted by the Investigator or designee and patient 
eligibility determined per QTc interval. Once enrolled, all ECGs should be 
interpreted prior to the patient leaving the clinic. 
Repeat ECG as clinically indicated if there are changes in cardiac medical 
condition or if the patient has reported concomitant medications with documented 
cardiac toxicities since the pre-study ECG.   
5.9 
Echocardiogram (ECHO) or Multi Gated Acquisition Scan (MUGA) 
ECHO or MUGA is required during pre-study for patients with known cardiac 
disease who are symptomatic within 3 months of planned first dose. Confirm 
sufficient cardiac function if testing has not already been performed within 30 
days of first dose. If a patient is asymptomatic at pre-study with no history of 
impairment of cardiac function, this procedure for eligibility is not required.

Study Treatment and Dose Assignment 
5.10.1 Cohort and Dose Assignment 
Phase 1:  
Patient dosing schedule, cohort and corresponding dose level assignment will be 
provided in writing from the Sponsor to the Investigator when the patient’s study 
identification number is assigned.   
Phase 2a: 
All patients will be assigned to the CRLX301 dose level that is determined to be 
the RP2D. Patient dosing schedule will be provided in writing from the Sponsor 
to the Investigator when the patient’s study identification number is assigned. The 
same treatment guidelines and assessments will apply as those specified in Phase 
1. 
5.10.2 Premedication Prior to CRLX301 Treatment for Both Schedules 
As a precaution to minimize the risk and/or severity of infusion-related 
hypersensitivity reactions, all patients will be provided premedication to allow for 
dosing the night prior (Day (-1), and also on day of CRLX301 infusion.

Once screening procedures have begun, patients will be provided with Day (-1) 
premedication along with instructions to be followed once eligibility is confirmed.  
NOTE: Research staff will call each patient within 72 hours prior to Day (-1) to 
remind the patient to take premedication. 
Prior to initiation of the CRLX301 infusion on day of dosing, sites should confirm 
that patient ingested premedication regimen the prior evening (Day (-1)). If 
patient did not take the premedication, the CRLX301 infusion will be initiated at 
discretion of the investigator. On day of dosing, premedication will be 
administered 30-90 minutes prior to the CRLX301 infusion.

If the subject has not experienced any infusion related reaction after the first three 
infusions of CRLX301, the dose of dexamethasone (both the night before and on 
day of CRLX301 dosing) may be tapered to 4mg for subsequent CRLX301 
infusions. If the subject continues to tolerate the subsequent three infusions of 
CRLX301, without experiencing any infusion related reaction, all “night prior” 
premedication may be stopped at the investigator's discretion. On the day of 
CRLX301 dosing, premedication are to continue throughout the study.

The example medications, route of administration, and dose indicated should be 
the medication-of-choice if clinically feasible. Note: It is particularly important to 
administer the premedication on the day of CRLX301 dosing via IV to achieve 
the quickest onset and maximum bioavailability of these medications to 
effectively prevent hypersensitivity/infusion reaction. The oral route is not 
recommended, especially for patients who have gastrointestinal tract (GI) tumor 
involvement, GI disease history and/or active GI symptoms (e.g., nausea, 
vomiting, diarrhea) that may negatively impact the absorption of the medications. 
If not clinically feasible or not site standard practice, the Investigator should 
discuss appropriate options with the medical monitor prior to Cycle 1 Day 1 
dosing for each patient. A prospective approval from the Medical Monitor or 
sponsor Medical Director may be provided in writing to acknowledge alternate 
route or alternate medication. All premedication will be recorded on the eCRF as 
concomitant medications with the name of the medication, dose, time 
administered, and the indication reported as “CRLX301 premedication”.

5.10.3 CRLX301 Administration, Management of Infusion Related Reactions and 
Treatment Compliance 
5.10.3.1 CRLX301 Administration 
Each CRLX301 infusion should start as slow as possible with no more than 15mL 
infused over the first 15 minutes. Provided the subject does not experience any 
infusion related symptoms during these 15 minutes, the rate of infusion can then 
be gradually increased to complete the infusion in approximately 120 minutes, 
inclusive of 50mL flush. If a subject has a history of infusion related reactions to 
other drug treatments, or has many environmental allergies (e.g., food, pollen), 
the total infusion time may be slowed during the first CRLX301 infusion and for 
all subsequent infusions, at the discretion of the investigator. If the Day (-1) 
premedications have been stopped and the patient has tolerated at least 3 infusions 
without Day (-1) premedications, the CRLX301 infusion rate may be increased 
(while maintaining the rule of no more than 15mL in first 15 minutes) to complete 
infusion in no less than 60 minutes, at discretion of investigator.

x A blood sample for tryptase should be drawn within 3 hours of onset of 
any infusion related reaction. Further, if a subject is to be re-treated, 
repeat blood sample for tryptase prior to each subsequent infusion. 
x For any ≤Grade 2 reaction, CRLX301 infusion may also be halted for 
the day, and the subject may return at the next scheduled visit for the 
next dose either as per study-specific CRLX301 administration 
procedures or per an Institutional desensitization protocol. For any 
subject that has experienced infusion related reaction while on study, all 
subsequent doses may be administered at a slower rate.  
5.10.3.3 Treatment Compliance 
All patients must meet hematology, bilirubin, AST, ALT and alkaline 
phosphatase eligibility criteria prior to receiving the first dose of CRLX301.  
Required hematology and chemistry lab results must be obtained within 3 days of 
the first dose date and within 24 hours of subsequent doses. 
Patients will receive all doses under the direct supervision of the Investigator and 
designated study personnel.  The intravenous infusion start time, stop time, 
volume infused, calculated dose and actual dose will be recorded.   
5.10.4 Dose Delay or Reductions or Treatment Discontinuation for Toxicity  
Modification and/or delay of treatment with CRLX301 will be based upon 
determination of hematologic and/or non-hematologic toxicities. Patients will 
continue to receive the same dose level of CRLX301 in Schedule 1 and in 
Schedule 2 as they were assigned at study entry unless a dose modification is 
required to manage AEs. In order to maintain dose-intensity and cumulative dose-
delivery on this study, reasonable efforts will be made to minimize dose reduction 
and treatment delays as specified below. Any patient whose treatment is delayed 
must be evaluated at least weekly until adequate hematologic and non-
hematologic parameters have recovered. All AEs and laboratory findings should 
be reviewed prior to dosing to determine whether any treatment modifications are 
required. The investigator should carefully assess all treatment-associated 
toxicities and, whenever possible, determine if they can reasonably be attributed 
to study drug.  
Dose delays for up to 21 days from the planned initiation of the next dose are 
permitted. Any dose delay of >21 days from planned date of next dose may result 
in withdrawal of the patient from further treatment upon review and discussion 
with Medical Monitor.  
Subsequent dosing days: 
For subsequent dosing days after the first dose, if a patient experiences ongoing 
Grade ≥2 related AE in Schedule 1 (Q3W) or Grade >2 related AE in Schedule 2 
(QW, no break or QW, 3 week on/1 week off), this will require a dose delay; if

AMENDMENT 9   DATE: 16DEC2016 
CONFIDENTIAL 
the AE resolves to adequate hematologic and non-hematologic parameters in ≤21 
days, this may require dose reduction.  Refer to the information below for both 
hematologic and non-hematologic toxicity management. 
It is also up to Investigator discretion to delay or reduce the dose for any Grade 1 
AE. 
If the AE does not resolve to adequate hematologic and non-hematologic 
parameters, and results in >21 day delay to initiation of the next dose Day 1, then 
the patient is withdrawn from further study treatment.   
A maximum of 2 dose reductions will be permitted per patient.  If a patient 
experiences repeat toxicities after 2 dose reductions, then subsequent treatment 
with CRLX301 will be halted and the patient will be withdrawn from the study. 
Patients who do not experience a DLT but are dosed in the same cohort where ≥2 
patients experienced DLTs, will be dose de-escalated to the next lower dose level 
at the next planned dosing date, as per the Dose Escalation Scheme.  This does 
not constitute 1 of the 2 permitted dose reductions for toxicity described above. 
Similarly, a change in dosing schedule from QW, no break to QW, 3 week on/1 
week off dosing will not constitute 1 of the 2 permitted dose reductions.  
 
Review all proposed dosing changes with the Medical Monitor and record on the 
eCRF. 
5.10.4.1 CRLX301 Treatment Modifications for Hematologic Toxicity  
For both schedules: 
Treatment decisions will be based on the absolute neutrophil count (ANC) (rather 
than the total white cell count (WBC) and the platelet count. 
Refer to Section 5.5.3: Prohibited Concurrent Medications or Therapies 
The use of hematopoietic cytokines and protective reagents are restricted to after 
first 3 weeks and as noted below: 
Patients will NOT receive prophylactic growth factors [filgrastim (G-CSF), 
sargramostim (GM-CSF), pegfilgrastim (Neulasta)] unless they experience 
recurrent neutropenic complications despite the treatment modifications specified 
below. 
Patients will NOT receive prophylactic thrombopoietic agents.

Patients may receive erythropoietin (EPO), iron supplements, and/or transfusions 
as clinically indicated for management of anemia. Treating physicians should be 
aware of prescribing information for the erythropoiesis stimulating agents 
(including Aranesp, Epogen, and Procrit) which note that there is a potential risk 
of shortening the time to tumor progression or disease-free survival, and that these 
agents are administered only to avoid red blood cell transfusions. They do not 
alleviate fatigue or increase energy. They should not be used in patients with 
uncontrolled hypertension. They can cause an increased incidence of thrombotic 
events in cancer patients on chemotherapy. The updated package inserts should be 
consulted.

if delay is < 2 weeks. If the dosing delay is ≥2 weeks, contact the Medical 
Monitor to discuss the appropriate dose to be given to the subject. 
x After the first 3 weeks of treatment, if the CRLX301 dose is held due to 
insufficient ANC and/or platelet counts, monitor counts at least weekly until they 
are adequate for treatment. In the event where counts not recovered to adequate 
count within 7 days, GCSF should be instituted. If counts recover adequately 
within the next 7 days, then CRLX301 will be administered in the same dose used 
prior to the hold. However, if subjects do not recover within 7 days after GCSF 
support, subjects might restart dosing at a reduced dose level after the ANC 
and/or platelet recovers to adequate counts with GCSG support or be taken off 
study if dosing delay is more than 3 weeks. 
x Therapy will be delayed for a maximum of 3 weeks until the required ANC 
(despite GCSF support) and platelet count values are achieved. Subjects who fail 
to recover adequate counts despite of GCSF support with a three-week delay will 
be removed from study therapy. 
5.10.4.2 CRLX301 Treatment Modifications for Non-Hematologic Toxicity 
For both schedules: 
x Patients with nausea, emesis, diarrhea, constipation, dehydration, electrolyte 
disturbance should receive appropriate medical management without dose 
modification. However, patients with persistent (> 72 hours) ≥Grade 3 
toxicity—in spite of optimal medical management require a reduction of 1 
dose-level and delay in subsequent therapy until recovered to Grade 1. 
x If a Grade 3 recovered to adequate hematologic and non-hematologic 
parameters by the planned next dosing day and this is the first episode of such 
event, dose reduction is not required. It is up to the investigator’s discretion to 
reduce the dose or not. 
x There will be no required dose modifications for alopecia, fatigue or 
hypersensitivity reaction.

data review for of the end of cohort meetings.  Details for collection, processing, 
storage, handling and shipment will be specified in the PK Manual. 
Phase 2a:  
All patients enrolled in Stage 1 expansion will have blood and urine samples 
collected for PK analysis.  
Only a subset of patients enrolled in Stage 2 expansion will have blood samples 
for PK collected. The number of patients undergoing blood collection for PK will 
be based on the samples obtained from Stage 1 and whether or not the same 
dosing schedule and dose level will be examined in Stage 2.  
If Schedule 1 is selected for Stage 2, PK samples will be collected until it is 
confirmed that at least 10 patients have completed serial PK sampling at both 
Cycle 1 and at least 1 repeat dose (Cycle 3 or 6).  
If Schedule 2 is selected for Stage 2, PK samples will be collected until it is 
confirmed that at least 10 patients have completed serial PK sampling at both first 
dose and at least one additional serial sampling day.  
No urine samples will be collected from patients enrolled in Phase 2a Stage 2.  
For all patients in the study, an unscheduled single plasma PK sample should be 
collected if they present in the clinic with any SAE that is possibly related to 
infusion of CRLX301, provided the visit does not already have a PK collection 
scheduled.  
Also, based on emerging data in the clinic and available PK data, the sponsor may 
remove collection of one or some blood PK sample time points without issuing a 
protocol amendment.  The sites and patients would be alerted in writing.

The required blood and urine sample collections for PK analysis are specified in 
the Tables below for each dosing schedule. Sample collection date and time, the 
time of the start and end of the CRLX301 IV infusion and the total volume of 
urine collected must be recorded on the eCRF and sample collection forms.   
Every effort should be made to collect plasma PK samples at the specified time 
points.  PK samples collected outside of the allowable window will be logged as a 
minor protocol deviation.

patient underwent pre-study activities, completed 7 cycles (Schedule 1), 21 weeks 
(Schedule 2 - QW, no break) or 20 weeks (Schedule 2 – QW, 3 week on/1 week 
off) of treatment, the EOS visit and Follow-Up, if applicable.  Actual blood 
volume collected is dependent upon what phase /stage of the study the patient is 
enrolled, whether they undergo additional coagulation testing for post-dose 
biopsy, whether pregnancy serum collection is required and if additional safety 
labs need to be repeated, etc.

Evaluation of Target Tumors 
5.15.1 CT Scans 
For patients undergoing tumor evaluation via RECIST v.1.1, CT scans for tumor 
measurement will be recorded following RECIST v.1.1 guidelines. CT scans are 
to be collected pre-study, and then repeated every 8-9 weeks until the patient 
discontinues study drug treatment due to disease progression: 
Schedule 1: First evaluation during Cycle 3 Day 15 (+6 days) and perform within 
1 weeks prior to Day 22 of Cycle 6, Cycle 9 etc.  
Schedule 2 (QW, no break): First evaluation during Week 9 (post-dose) and 
complete before Week 10 dose, then during Week 18 (post-dose), Week 27 (post-
dose), etc. 
Schedule 2 (QW, 3 week on/1 week off): First evaluation complete before Week 9 
dose, then prior to Week 17 dose, prior to Week 25 dose, etc. 
Repeat CT Scans for tumor measurement at End-of-Study visit if prior CT scan 
and tumor evaluation is >3 weeks.  
If a complete or partial response per RECIST v.1.1 criteria is reported, then repeat 
CT scan approximately 3 - 4 weeks later for confirmation, per Investigator 
discretion. 
If stable response per RECIST v.1.1 criteria is reported, then continue repeat CT 
scan 8-9 weeks later for confirmation, per Investigator discretion.

AMENDMENT 9   DATE: 16DEC2016 
CONFIDENTIAL 
Patients who are discontinued from study treatment for reasons other than disease 
progression will continue to have tumor evaluation by RECIST1.1 until another 
anti-cancer treatment is started, progression of disease, death, loss to follow up or 
withdrawal of consent, whichever comes first. Therefore, continued evaluations 
may be possible for some patients after the End-of-Study visit. 
5.15.2 Bone Scans 
Bone scans for tumor measurement will also be required and recorded for any 
CRPC patient enrolled into Phase 2a following PCWG2 criteria (see Section 
5.15.3: Alternative Evaluation Methods). Bone scans are to be collected pre-
study, and then repeated every 8-9 weeks until the patient discontinues study drug 
treatment due to disease progression: 
Schedule 1: First evaluation during Cycle 3 Day 15 (+6 days) and perform within 
1 weeks prior to Day 22 of Cycle 6, Cycle 9 etc.  
Schedule 2 (QW, no break): First evaluation during Week 9 (post-dose) and 
complete before Week 10 dose, then during Week 18 (post-dose), Week 27 (post-
dose), etc. 
Schedule 2 (QW, 3 week on/1 week off): First evaluation complete before Week 9 
dose, then prior to Week 17 dose, prior to Week 25 dose, etc. 
 
Repeat bone scans for tumor measurement at End-of-Study visit if prior bone scan 
and tumor evaluation is >3 weeks.  
5.15.3 Alternative Evaluation Methods 
If an alternative tumor evaluation methodology consistent with the tumor type is 
preferred, the Investigator will review this with the Medical Monitor when the 
patient enters the study, and plan to use the same methodology during the entire 
study period. The same schedule for evaluations will apply as for CT Scans. 
For Phase 2a prostate cancer patients, the alternative tumor evaluation method 
will be the PCWG2 criteria (see reference #33).  PSA in prostate patients will be 
collected pre-study, every three to four weeks as per the Schedule of Procedures 
and at the EOS visit only if it has been >21 days since the last PSA measurement.  
 
Patients who are discontinued from study treatment for reasons other than disease 
progression will continue to have tumor evaluation by the selected alternative 
evaluation method until another anti-cancer treatment is started, progression of 
disease, death, loss to follow up or withdrawal of consent, whichever comes first. 
Therefore, continued evaluations may be possible for some patients after the EOS 
visit.

5.16 
Tumor Marker Data 
Tumor marker data is collected only if appropriate for tumor-type and if already 
being performed as part of the patients Standard of Care. This includes treatment 
response markers (e.g. CA-125 for ovarian cancer, CA19-9 for pancreatic cancer, 
etc.) and tumor genotype markers (e.g. BRAF mutation status for melanoma, 
KRAS mutation status for colon cancer, EGFR status for lung cancer, etc.) The 
data should be entered into the eCRF. If tumor marker data is available prior to 
the first dose of CRLX301 (baseline) then additional data should be entered into 
the eCRF as available.  
5.17 
Pharmacodynamic (PD) Sample: Pre- and Post-Dose Biopsy 
Additional pharmacodynamic evaluations may be conducted by the Sponsor if 
tumor biopsies are obtained pre- and post- CRLX301 infusion.  The tissue will be 
used for additional research to include evaluation of markers for efficacy (e.g. 
proliferation, apoptosis, and cell cycle) and CRLX301 localization; it may also 
include genetic testing related to the cancer diagnosis for research purposes only, 
no other genetic testing on tumor tissue will be performed.  Individual patient 
results of any disease related genetic testing will not be provided to the 
Investigators or patients. 
Tumor biopsy is optional and is only required if accessible and feasible to collect 
and with consent of the patient. Collect a tissue sample pre-study prior to the first 
dose. Collect the post-dose biopsy as defined in the Schedule of Procedures 
Detailed instructions on tissue preparation and shipping will be provided to the 
site separately.  
5.18 
Blood Sample Collection for Additional Biomarker Research 
For Phase 2a only additional blood samples will be collected for additional 
exploratory research. Blood will be separated into peripheral blood mononuclear 
cells (PBMCs) and plasma. 
Pre- and post-study treatment blood samples will be used for analysis of genomic 
DNA for genetic alterations pertinent to the subject’s cancer diagnosis. A targeted 
panel of genes will be processed using next generation sequencing (NGS) to allow 
germline and tumor-specific mutations, amplifications and translocations (among 
other alterations) to be identified with high sensitivity and specificity. Plasma 
collected at progression will be used to determine whether new mutations may 
identify a potential marker for disease progression during treatment. 
 
A total of 6 mL of blood will be collected at each time point as per the Schedule 
of Procedures for each dosing schedule. 
For both schedules a total of 60 mL of blood will be collected during the study as 
per the time points detailed in each Schedule of Procedures.

The samples will be shipped to a central laboratory. Detailed instructions on 
collection, processing, and shipping of samples will be provided to the sites prior 
to enrollment into Phase 2a.  
5.19 
Archived Tumor Tissue 
Collection of archived tumor tissue is optional. For all patients who consent, up to 
12 slides from previously archived tumor tissue may be collected. Availability of 
archived tissue is not required in order to participate in the study. The site will be 
instructed to indicate during the pre-study visit if archived tissue is available, 
when the tissue was collected, and that the patient has consented to use of the 
tissue. Additional exploratory research may include evaluation of markers for 
efficacy (e.g. proliferation, apoptosis, and cell cycle) and CRLX301 localization; 
it may also include genetic testing related to the patient’s cancer diagnosis for 
research purposes only, no other genetic testing will be performed. Individual 
patient results of any disease related genetic testing will not be provided to the 
Investigators or patients.  
The trigger for preparation and shipment of slides will be a request in writing 
from the sponsor. The written request must occur prior to each site’s completion 
of the study. Detailed instructions on collection, preparation of slides, and 
shipping of samples will be provided to the sites at a future date.  
5.20 
Circulating Tumor Cells (CTCs) 
Whole blood will be collected for CTC analysis from patients enrolled in Phase 
2a Stage 1 expansion only. The samples will be used to explore 
pharmacodynamic effects of CRLX301 on tumor cells.27, 28 Fresh whole blood 
samples will be shipped to a central vendor. The samples must be shipped on the 
same day of collection in order to be analyzed within 24 hours.  Refer to the 
Schedule of Procedures for each dosing schedule for collection time points.  
Detailed instructions will be provided in the study binder prior to initiation of 
Phase 2a Stage 1.  
5.21

Whole blood will be collected for MPS function analysis from patients enrolled in 
Phase 2a Stage 1 expansion only. The samples will be used to explore whether or 
not MPS plays a role in the clearance of CRLX301.29, 30, 31 Fresh whole blood 
samples will be shipped to a central vendor. The samples must be shipped on the 
same day of collection in order to be analyzed within 24 hours.  Refer to the 
Schedule of Procedures for each dosing schedule for collection time points.  
Detailed instructions will be provided in the study binder prior to initiation of

End-of-Study Visit  
All dosed patients will have an End-of-Study (EOS) Visit 30 days (+10d) post last 
dose of study drug or at the time of early withdrawal if the patient cannot feasibly 
or is unwilling to return for the visit at the later date. 
If a patient discontinues from study drug and receives an investigational treatment 
or anti-cancer therapy prior to the 30 days post last dose of CRLX301 End-of-
Study visit, such treatment must be recorded on the eCRF.  Every attempt should 
be made to complete the End-of-Study visit 30 days post the last dose of 
CRLX301 prior to initiating other cancer treatment. AEs that occur after the 
initiation of new cancer treatment will not be collected.  
Patients will be followed for AEs and SAEs including clinically significant 
abnormal laboratory values.  In addition, any dosed patients who discontinue from 
the study due to an AE deemed to be related to study drug must be followed to 
report the final outcome of the AE as resolved, or symptoms returned to baseline 
or determined to be due to a chronic condition, or death.    
Discontinued patients who fail to return for an End-of-Study Visit within the 
designated time period must be requested in writing to return.  A copy of the letter 
will be kept by the study center with the source documentation.   
The reason for discontinuation from the study will be recorded on the End-of-
Study page of the Case Report Form (eCRF).   
The following procedures will be performed at the End-of-Study Visit: 
x Physical examination  
x ECOG performance status 
x Assess AEs and vital signs  
x Assess concomitant medication use  
x Collect blood and urine samples for hematology, chemistry and 
urinalysis, and pregnancy test if applicable  
x 12-lead ECG 
x Collect blood for biomarker (Phase 2a only) 
x Collect blood for CTC (Phase 2a Stage 1 only) 
x Collect PSA for CRPC patients only if prior PSA measurement is >14

progression will continue to have tumor evaluation by RECIST1.1 or by 
alternative response evaluation for specific tumor type every 8-9 weeks or per 
Investigator discretion until another anti-cancer treatment is started, progression 
of disease, death, loss to follow up or withdrawal of consent, whichever comes 
first. Therefore, continued tumor evaluations may be possible for some patients 
after the EOS Visit.  
PSA will also be collected for CRPC patients only on Phase 2a.  PSA during 
follow-up will be done on the same scheduling as tumor evaluation.

DISCONTINUATION FROM TREATMENT AND STUDY WITHDRAWAL 
6.1 
Reasons for Discontinuation from Treatment 
Eligible patients who are enrolled into the study will be discontinued from study 
treatment if any of the following occur: 
x Documented radiographic or clinical progression of disease unless there is 
evidence of clinical benefit from the study drug and the investigator 
believes it is in the patient’s best interest to continue the treatment despite 
disease progression 
x Grade 4 hypersensitivity/infusion related reaction (may also be 
discontinued for Grade 3; see Table 7) 
x AE with clinically unacceptable toxicities (unless there is evidence of 
sustained therapeutic benefit and the investigator believes it is in the 
patient’s best interest to continue the treatment despite the toxicity) 
including: 
o unresolved related AE >Grade 2 that causes a delay of >21 days 
from planned initiation of next dose of CRLX301 
o repeat toxicities after 2 dose reductions 
o bilirubin >1.2 ULN, or AST and/or ALT >1.5 × ULN concomitant 
with alkaline phosphatase >2.5 × ULN; if either of these are 
unresolved for >21 days from planned next dose date 
o any other clinically unacceptable toxicity (in agreement with the 
Sponsor/Medical Monitor) 
x Withdrawal of consent 
x Subject non-compliance with study schedule 
x Protocol violation, (including lack of compliance or excessive deviations 
with study schedule) in agreement with the Sponsor/Medical Monitor 
and/or Study Director  
x Lost to follow-up (after repeated efforts for >30 days have been made to 
contact the patient including letters sent by registered mail) 
x Request for discontinuation by a regulatory agency (i.e. FDA) 
x Investigator decision (in consultation with the Safety Medical Monitor 
and/or Medical Director and the patient) if there are changes in the 
patient’s medical condition and/or intercurrent illness that render the 
patient unacceptable for further treatment. The reason for removal must be 
documented in the eCRF.

STUDY DRUG AND PHARMACY INSTRUCTIONS 
7.1 
Study Drug  
CRLX301 is a conjugate of docetaxel and a linear cyclodextrin-based polymer 
(CDP).  The active drug unconjugated from the polymer is docetaxel. CRLX301 
contains a taxane antineoplastic agent, which can cause fetal harm; therefore, 
women of childbearing potential must agree to use of adequate form(s) of 
contraception. 
The Sponsor will provide the study center with drug supplies. CRLX301 will be 
supplied in a single form: 20 ml single-use vials containing 25 mg of docetaxel 
equivalents (approximately 125 mg of polymer-drug conjugate). The formulation 
contains mannitol as a bulking agent.  The drug is supplied in clear glass vials and 
appears as a white to off-white solid and transparent solution when reconstituted. 
CRLX301 for injection is stored at refrigerated conditions (2° - 8°C) and should 
only be accessible to authorized individuals.   
Refer to the CRLX301 Investigator’s Brochure for details on CRLX301-101 drug 
product and the CRLX301-101 Pharmacy Manual for details on storage, stability, 
reconstitution, preparation, handling, administration and accountability. 
7.2 
Study Drug Dose Calculation and Administration  
7.2.1 
Body surface Area Calculation 
Body surface area (BSA) calculations will be performed according to institutional 
practices. Every attempt should be made to follow the updated ASCO clinical 
practice guidelines including the guideline for dosing obese patients.32 
BSA is calculated according to the following method or alternate method as per 
the institutional practices: 
BSA (m²) = 0.20247 × height (m)0.725 × weight (kg)0.425 
A change in body weight of >10% will require recalculation of BSA if the change 
is attributed to dry weight. 
 
Refer to the Pharmacy Manual for detailed dose calculation instructions.  
7.2.2 
CRLX301 Dose Reconstitution 
After reconstitution the total amount of CRLX301 to be injected into the IV bag 
of normal saline is determined from the assigned patient treatment cohort dose 
level as mg/m2.  
Refer to the CRLX301-101 Pharmacy Manual for detailed reconstitution

reactions to other drug treatment(s) or who have environmental allergies (e.g., 
food, pollen).  
7.3 
Study Drug Accountability 
The PI or appropriately trained designee will maintain an accurate record of the 
receipt of the investigational products shipped by the Sponsor’s contracted drug 
distribution center, including the date and quantity received.  In addition, an 
accurate drug disposition record will be kept that specifies the amount 
administered to each patient and the date of administration.  This inventory record 
must be available for inspection at any time, and copies of this record will be 
provided to the Sponsor at the conclusion of the study.  Also at the completion of 
the study, the PI (or appropriately trained designee) will provide the Sponsor with 
a complete record of investigational product accountability. 
Empty or partially used vials of study drug will be destroyed at the study center 
per study center procedures and documentation of destruction will be reviewed by 
the Sponsor designated Study Monitor. 
All unused study drug must be accounted for by the site and verified by the 
Sponsor designated Study Monitor prior to destruction at the study center or 
returned to the appropriate depot.  Determination of destruction or return will be 
provided by the Sponsor.

ADVERSE EVENTS 
8.1 
Definition of Adverse Events and Adverse Reactions 
An AE is defined as any unfavorable and unintended sign (e.g., an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a 
drug, experienced by a patient during the clinical study or the specified safety 
follow-up period, regardless of relationship to study drug. 
An adverse reaction is any adverse event caused by a drug. 
A suspected adverse reaction is any adverse event for which there is a reasonable 
possibility that the drug caused the adverse event.  
8.2 
Evaluation of Adverse Events 
The investigator will determine the seriousness, severity (intensity), and causality 
of an AE to the use of the study drug based on the definitions described below. 
8.2.1 
Serious Adverse Events (SAE) and Suspected Unexpected Serious Adverse 
Reactions (SUSAR) 
An SAE is any untoward medical occurrence that at any dose results in any of the 
following outcomes, regardless of relationship to study drug. 
Notify Sponsor via the study designated SAE Submission Line email or fax 
within 24 hours per instructions in the Investigator Site File; and document events 
on eCRF. 
Death: All deaths, regardless of cause or relationship, must be reported for 
patients on study and for deaths occurring within 30 days of last study drug dose.  
Note: Death is an outcome of an AE, and not an AE in itself. Reports of death due 
to disease progression or progressive disease must be associated with a diagnosis 
caused by progression of disease, e.g., respiratory failure. The event(s) that caused 
death (e.g., illness, accident) is the SAE. Death due to progressive disease will not 
be considered an SAE. Death due to any other cause(s) must also be reported as 
an outcome of the reportable SAE.  
Life-threatening adverse drug event: This includes any adverse drug event that 
places the patient, in the view of the investigator, at immediate risk of death from 
the reaction as it occurred (i.e., this does not include a reaction that had it 
occurred in a more severe form, might have caused death).

Protocol No.: CRLX301-101 
Page 103 of 133  
AMENDMENT 9   DATE: 16DEC2016 
CONFIDENTIAL 
Inpatient hospitalization or prolongation of existing hospitalization: “In-
patient hospitalization” means the patient has been formally admitted to a hospital 
for medical reasons, for any length of time. This may or may not be overnight. It 
does not include presentation to and care within an emergency department. 
Complications that occur during hospitalizations are AEs. If a complication 
prolongs hospitalization, it is a SAE.  
Persistent or significant disability/ incapacity: A disability is defined as any 
substantial disruption of a person’s ability to conduct normal life functions.  
Congenital anomaly/birth defect: Includes spontaneous miscarriage, Structural 
or functional anomalies, including metabolic disorders, which are present at the 
time of birth.  
Important medical event: An event that may not result in death, be life-
threatening, or require hospitalization may be considered a serious adverse drug 
event when, based upon appropriate medical judgment, it may jeopardize the 
patient and may require medical or surgical intervention to prevent any of the 
outcomes listed in this definition or meets the criteria for a SUSAR.  
Serious unexpected serious adverse reaction (SUSAR) is any adverse event for 
which there is a reasonable possibility that the study drug caused the adverse 
event of which the specificity or severity is not consistent with those noted in the 
current protocol and/or IB, and meets one of the above criteria for serious. This 
refers to any AE that has not been previously observed, (e.g., included in the IB), 
rather than from the perspective of such an event not being anticipated from the 
pharmacological properties of the product. 
Notify sponsor via the study designated SAE Submission Line email or fax by the 
next business day. 
8.2.2 
Unexpected Suspected Adverse Reaction 
An unexpected suspected adverse reaction is any adverse event for which there is 
a reasonable possibility that the study drug caused the adverse event, the 
specificity or severity of which is not consistent with those noted in the current 
protocol and/or Investigator’s Brochure. This refers to any AE that has not been 
previously observed, rather than from the perspective of such an event not being 
anticipated from the pharmacological properties of the product. Unexpected 
suspected adverse reaction(s) which are not serious are submitted to the Sponsor 
on the Serious Adverse Event /Adverse Event of Special Interest form and noted 
as not serious.  
Notify sponsor or sponsor representative via the study designated SAE 
Submission Line email or fax the next business day; document on eCRF.

8.2.3 
Other Adverse Events of Special Interest 
For all patients, the following adverse events are categorized as Adverse Events 
of Special Interest (AESI) 
x infusion-related hypersensitivity reaction(s) of any Grade 
x >Grade 2 non-infective cystitis 
x >Grade 2 bilirubin, ALT, or AST elevation 
x ≥Grade 3 fluid retention (in the form of edema, pleural effusion, or weight 
gain)  
Notify sponsor or sponsor representative within 3 business days of any non-
serious AESIs by documenting on the eCRF. 
8.2.4 
Non-Serious Adverse Events  
All other AEs, not fulfilling the previous definitions, are classified as non-serious. 
Document non-serious AEs on the Adverse Event page of the case report form 
(eCRF). 
8.2.5 
Laboratory Adverse Events  
All laboratory results must be filed in the patient’s medical record and monitored. 
The Investigator or designee must review laboratory results in a timely manner 
demonstrated by signature / date and assignment of clinical significance 
assessment. Non-clinically-significant laboratory abnormalities, i.e., minor 
deviations from the normal range, are expected and it is likely that no medical 
intervention will be required. Abnormal laboratory results should not be 
considered AEs unless they are associated with a diagnosis.  
Any grade laboratory abnormality that is considered to be clinically significant by 
the Investigator will be recorded on the AE eCRF. An abnormal test result will be 
considered an AE if:  
It is not associated with an already reported AE, diagnosis, or pre-existing 
condition;  
There is a change in concomitant medication or intervention is needed, in 
direct response to a Grade 3 or 4 laboratory result;  
Investigator considers the laboratory result to be clinically significant.  
All such laboratory abnormalities should be repeated and reassessed for 
“seriousness” by the Investigator or designee as soon as possible. If a result meets 
the regulatory definition of “serious”, it should be reported as an SAE following 
regulatory and protocol requirements. Repeat laboratory tests should be 
performed regularly to monitor patient status.

8.2.6 
Severity of Adverse Events  
The severity of each AE will be graded by the Investigator according to the NCI-
CTCAE Version 4.03.  
For AEs not listed in the NCI-CTCAE, the following similar grading system 
should be used: 
Grade 1 Mild AE 
Grade 2 Moderate AE 
Grade 3 Severe AE 
Grade 4 Life-threatening or disabling AE 
Grade 5 Death related to AE 
Severity, which is a description of the intensity of manifestation of the AE, is 
distinct from seriousness, which implies a patient outcome or AE-required 
treatment measure associated with a threat to life or functionality.  An AE 
assessed as Grade 4 based on the NCI-CTCAE grades may or may not be assessed 
as serious based on the seriousness criteria. 
The severity rating must be recorded on the appropriate AE reporting page of the 
patient’s CRF. 
8.2.7 
Relationship to Study Drug  
The Investigator will attempt to assess the relationship of the event and record it 
as unrelated, unlikely-related, possibly related, probably related, and definitely 
related. 
Unrelated: This category applies to those AEs which, after careful medical 
consideration, are clearly felt to be due to extraneous causes (disease, 
environment, etc.) that are unrelated to the administration of study drug.  
Unlikely-related:  This category applies to those AEs which, after careful 
medical consideration, are felt unlikely to be related to the administration of the 
study drug. The relationship of an AE to the study drug can be considered 
unlikely if (must have first 2 criteria below):  
x It does not follow a reasonable temporal sequence from administration of 
the drug 
x It could readily have been a result of the patient’s clinical state, 
environmental or toxic factors, or other modes of therapy administered to 
the patient 
x It does not follow a known response pattern to the suspected drug 
x It does not reappear or worsen when the drug is re-administered

Possibly related: This category applies to AEs which, after careful medical 
consideration, are considered not likely to be related, but the possibility cannot be 
ruled out with certainty. The relationship of an AE to the study drug can be 
considered possible if (must have first 2):  
x It follows a reasonable temporal sequence from administration of the study 
drug; 
x It could readily have been a result of the patient’s clinical state, 
environmental or toxic factors, or other modes of therapy administered to 
the patient; 
x It follows a known response pattern to the suspected study drug. 
Probably related: This category applies to AEs which, after careful medical 
consideration, are felt with a high degree of certainty to be related to the 
administration of the study drug. The relationship of an AE to the study drug can 
be considered probable if (must have first 3 criteria below):  
x It follows a reasonable temporal sequence from administration of the drug; 
x It could not be reasonably explained by the known characteristics of the 
patient’s clinical state, environmental or toxic factors or other modes of 
therapy administered to the patient; 
x It disappears or decreases upon cessation of drug, dose delay, or dose 
reduction; 
x It follows a known response pattern to the suspected drug. 
Related: This category applies to AEs, which, after careful medical 
consideration, are felt to be related to the administration of the study drug. The 
relationship of an AE to the study drug can be considered related if (must have

Expedited Reporting of SAEs, Patient Death and Unexpected AE 
8.3.1 
Time-Frame for Reporting  
Any SAE, unexpected (and severe) AE experienced by the patient from time of 
informed consent through 30 days after receiving the last dose of study drug, 
regardless of relationship to study drug, or any death that occurs more than 30 
days after the last dose of study drug, and is believed to be study drug-related, 
must be promptly reported within 24 hours of the Investigator becoming 
aware of the event to the study designated SAE Submission Line email or fax. 
AEs that do not meet the definition for severe or unexpected should be collected 
from the time of first dose through 30 days after the last dose of study drug. 
If a non-serious AE is reported from time of informed consent up to the first dose 
it should be recorded in medical history. 
8.3.2 
Information to be Submitted for Reportable Event 
At the time of the initial contact(s), the Investigator must report to the Medical 
Monitor information for completion of an expedited Safety Report. The Sponsor 
representative will require all of the following information about the patient and 
the event:  
x Patient identification code, gender, and age or date of birth 
x Height, weight, or body surface area (where required for dose calculation) 
x Underlying diagnosis and extent of disease 
x Lot number and expiration date of study drug  
x Dose, route, frequency, and duration of study drug administered 
x Date of study drug administration 
x Description of event, including date of onset and duration 
x Date of death (if applicable) 
x Intervention(s) required 
x Concomitant therapy (including regimen[s] and indication) 
x Pertinent laboratory data/diagnostic study (including dates) 
x Pertinent medical history

In addition to the above information, the sponsor will require the investigator’s 
assessment of the following:  
x Severity of the AE 
x Relationship of the AE to study treatment 
x Outcome of the AE 
Study center staff must transmit an SAE report form to the Sponsor within 
24 hours of knowledge of the event, even if an initial report is made by telephone, 
as well as any relevant Pregnancy Report forms.  Refer to the Investigator Site 
File for copies of the forms and instructions for reporting to the Sponsor.  
SAE Report Forms and Pregnancy Report Forms should be submitted to the 
study designated SAE submission email or fax. 
Supplemental information should be submitted as soon as available. 
8.4 
Recording Adverse Events 
All AEs and SAEs will be recorded, evaluated, and documented by the 
Investigator on source documents and on designated eCRF pages. 
Patients are to be questioned regarding any AEs or SAEs at every scheduled and 
non-scheduled visit.  Patients will be asked to volunteer information through 
open-ended questioning.  AEs will also be identified by physical examination and 
review of laboratory results. The Investigator or designee will record all pertinent 
information on the appropriate AE reporting page of the patient’s eCRF whether 
or not they are considered causally related to the investigational product. 
The Investigator should attempt to establish a diagnosis of the AE based on signs, 
symptoms, and/or other clinical information. In such cases, the diagnosis should 
be documented as the AE verbatim term rather than individual signs/symptoms.  
For every AE, the Investigator must document the following: 
x Diagnosis or description of event 
x Onset date 
x Assessment of the severity 
x Assessment causal relationship to the investigational product 
x Assessment of seriousness of the event (i.e. whether it is an SAE) 
x Method of treatment taken for the AE 
x Action taken related to study drug include the following: dose 
interruption, dose delay, dose reduction, or study drug discontinuation

x Outcome of event and end date; all SAEs must be followed until 
resolution, patient death or until the SAE is deemed stable or irreversible 
x Phase 1 during Cycle 1 only: any event which meets the criteria as a DLT 
will be noted as such on the eCRF 
8.5 
Exposure to Study Drug during Pregnancy 
The Investigator must report any pregnancy (including the pregnancy of a male 
patient’s partner), even if no AE has occurred, on a Pregnancy Report Form 
within 24 hours of the Investigator becoming aware of the pregnancy. See the 
Investigator Site File for a copy of the form and instructions on how to submit this 
information to the Sponsor.  
Female patients who become pregnant while on the study will be immediately 
discontinued from study treatment, and complete the End-of-Study visit at 30 
days post-last dose follow-up period, reporting all AEs including any related to 
the pregnancy. In addition, the Investigator will make every attempt to confirm 
the outcome of the pregnancy and report this on a follow-up Pregnancy Report 
form.    
8.6 
End-of-Study Post-treatment Safety Follow-up  
In this study, the post-treatment safety follow-up period is defined as 30 days after 
the last dose of CRLX301.  All AEs occurring during the study period from the 
time of the first dose to the last day of the 30-day post-treatment follow-up period 
will be reported. All patients should be instructed to report AEs or SAEs 
occurring during the 30-day post-treatment safety follow-up period. 
If a patient discontinues from study drug and is planning to receive an 
investigational treatment or anti-cancer therapy prior to the 30 days post last dose 
of CRLX301 every attempt should be made to complete the End-of-Study visit 
prior to initiating other cancer treatment.  AEs that occur after the initiation of 
new cancer treatment will not be collected. 
Unresolved study drug related (see Section 8.2.7: Relationship to Study Drug for 
definition) AEs and SAEs at the time of treatment discontinuation or new study 
drug-related AEs and SAEs that occur during the 30 day post last dose follow-up 
period will be followed until they have, in opinion of the Investigator, resolved to 
baseline, stabilized, or are deemed to be irreversible.

EVALUATION OF ANTI-TUMOR ACTIVITY 
Tumor response evaluations will be performed by following RECIST guidelines, version 
1.1 or by alternate methodology consistent for tumor type. A patient will be considered 
evaluable for efficacy if the patient received at least 1 dose of study drug and had either: 
x a pre-study CT scan and at least 1 follow-up CT scan assessment during the study 
period. CT scan assessments should be completed every 8 - 9 weeks if possible; 
and, whenever feasible a CT scan should be repeated 4 weeks after a partial or 
complete response is observed. Changes in the largest diameter (unidimensional 
measurement) of the tumor lesions and the shortest diameter in the case of 
malignant lymph nodes are used in the RECIST criteria. 
x a pre-study alternative response evaluation consistent with tumor type and at least 
one follow-up alternative response evaluation during the study period. 
NOTE: the rest of this section describes evaluation of anti-tumor activity via 
RECIST1.1. If an alternative response evaluation is used, please refer to the appropriate 
criteria. For example, for prostate cancer, see reference #33 for the PCWG2 criteria. 
9.1 
Measurable Disease and Target Lesions  
9.1.1 
Measurable Disease  
Measurable lesions are defined as those that can be accurately measured in at least 
1 dimension (longest diameter to be recorded) as >20 mm by chest x-ray or as 
>10 mm with CT scan, MRI, or calipers by clinical exam. All tumor 
measurements must be recorded in millimeters (or decimal fractions of 
centimeters).  
Tumor lesions that are situated in a previously irradiated area may or may not be 
considered measurable.  
To be considered pathologically enlarged and measurable, a malignant lymph 
node must be >15 mm in short axis when assessed by CT scan (CT scan slice 
thickness recommended to be no greater than 5 mm). At baseline and in follow-
up, only the short axis will be measured and followed.  
All other lesions (or sites of disease), including small lesions (longest diameter 
<10 mm or pathological lymph nodes with ≥10 to <15 mm short axis), are 
considered non-measurable disease. Bone lesions, leptomeningeal disease, ascites, 
pleural/pericardial effusions, lymphangitis cutis/pulmonitis, inflammatory breast 
disease, and abdominal masses (not followed by CT or MRI), are considered as 
non-measurable.

9.1.2 
Target Lesions 
All measurable lesions up to a maximum of 2 lesions per organ and 5 lesions in 
total, representative of all involved organs, should be identified as target lesions 
and recorded and measured at baseline. Target lesions should be selected on the 
basis of their size (lesions with the longest diameter), be representative of all 
involved organs, and lend themselves to reproducible repeated measurements. It 
may be that, on occasion, the largest lesion does not lend itself to reproducible 
measurement in which case the next largest lesion that can be reproducibly 
measured should be selected. The sum of the diameters (longest for non-nodal 
lesions, short axis for nodal lesions) for all target lesions should be calculated and 
reported as the baseline sum diameters. If lymph nodes are to be included in the 
sum, then only the short axis is included. The baseline sum diameters will be used 
as a reference to further characterize any objective tumor regression in the 
measurable dimension of the disease.  
9.2 
Response Evaluation of Target Lesions 
Complete Response (CR): Disappearance of all target lesions. Any pathological 
lymph nodes (whether target or non-target) must have a reduction in short axis to 
<10 mm.  
Partial Response (PR): At least a 30% decrease in the sum of the diameters of 
target lesions, using the baseline sum diameters as a reference.  
Progressive Disease (PD): At least a 20% increase in the sum of the diameters of 
target lesions, taking as a reference the smallest sum on study (this includes the 
baseline sum if that is the smallest on the study). In addition to the relative 
increase of 20%, the sum must also demonstrate an absolute increase of at least 5 
mm. (Note: the appearance of 1 or more new lesions is also considered 
progression).  
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR, nor sufficient 
increase to qualify for PD, taking as a reference the smallest sum diameters while 
on the study.  
9.3 
Evaluation of Best Overall Response and Disease Control Rate 
The best overall response is the best response recorded from the start of the 
treatment until disease progression/recurrence (taking the smallest measurements 
recorded since the treatment started as a reference for progressive disease).  
The duration of overall response is measured from the time the measurement 
criteria are met for CR or PR (whichever is first recorded) until the first date that 
recurrent or progressive disease is objectively documented.

AMENDMENT 9   DATE: 16DEC2016 
CONFIDENTIAL 
Duration of stable disease is measured from the start of the treatment until the 
criteria for progression are met, taking the smallest measurements recorded since 
the treatment started, including the baseline measurements, as a reference. 
 
The objective response rate is the proportion of all patients with PR or CR, from 
the start of treatment until disease progression/recurrence (taking as reference for 
progressive disease the smallest measurements recorded since the start of 
treatment).  
 
The disease control rate is the proportion of all patients with SD for 8-9 weeks, or 
PR, or CR, from the start of treatment until disease progression/recurrence (taking 
as reference for progressive disease the smallest measurements recorded since the 
start of treatment).   
9.4 
Progression-Free Survival  
Progression-free survival (PFS) is defined as the duration of time from the start of 
treatment to the time of progression or death, whichever occurs first while on the 
study.

10.7 
Efficacy Analyses 
Exploratory analyses of efficacy will be undertaken by evaluating the RECIST 
findings or by alternative response evaluations for specific tumor types. All 
RECIST findings for target lesions or specific tumor type response evaluations 
will be listed. In addition, the following parameters will be determined: 
x Best overall response 
x Duration of overall response 
x Duration of stable disease 
x Objective response rate  
x Disease control rate

For the analysis of best overall response, objective response rate and disease control 
rate, summary tables presenting the number and proportion of responders and non-
responders, together with the two-sided 95% Pearson-Clopper confidence intervals 
for response rates will be produced.   
The analysis of time to event endpoints, such as duration of overall response, 
duration of stable disease, and progression free survival, will be based on the 
survival function, which is the probability to stay event-free beyond a certain point 
in time. The survival function will be estimated by the Kaplan-Meier method. The 
survival function will be summarized for 25th percentile, median, and 75th percentile 
and their 95% confidence intervals. The plot of Kaplan-Meier estimates of survival 
functions will be presented.  
 
10.8 
Pharmacokinetic Analyses 
Plasma samples will be collected from all patients in Phase 1 and a subset of 
patients in Phase 2a to evaluate the PK of total and unconjugated docetaxel in 
plasma. PK parameters will be calculated using noncompartmental analysis with 
the software program WinNonlin (version 15.3 or higher).  Actual sampling times 
will be used to calculate PK parameters in this study.  The plasma PK parameters 
will include area under the concentration versus time curve (AUC), maximum 
concentration (Cmax), half-life (t1/2), volume of distribution (Vd), clearance (CL) 
for both total and unconjugated. Urine samples will be collected from patients in 
Phase 1 to evaluate the urinary excretion of total and unconjugated docetaxel. PK 
parameters in urine will include the maximum concentration (Cmax), amount of 
drug in the urine, % of drug eliminated in the urine.  
For PK data the arithmetic mean, standard deviation (SD), median, minimum, 
maximum, coefficient of variation (CV%), geometric mean and geometric 
coefficient of variation (geo CV%) values will be presented. Details of the PK 
analyses will be provided in the Statistical Analysis Plan (SAP).

10.9 
Safety Analyses 
The safety analysis will be performed based on the Safety Population as specified 
in the SAP.  Safety variables will include AEs, clinical laboratory parameters, 
vital signs, and ECG parameters.  For each safety parameter, the last assessment 
made before the first dose of the investigational product for each period will be 
used as the baseline for all analyses of that safety parameter. 
10.9.1 Adverse Events 
An AE (classified by preferred term) that occurs during the treatment period will 
be considered a TEAE if it was not present before the first dose of investigational 
product or if it was present before the first dose of investigational product but 
increased in severity during the treatment period.  If more than 1 AE is reported 
before the first dose of study drug and is coded to the same preferred term, the AE 
with the greatest severity will be used as the benchmark for comparison with the 
AEs that were also coded to that preferred term and that occurred during the 
period.  An AE that occurs more than 30 days after the last dose of investigational 
product will not be counted as a TEAE, unless recommended by the Safety 
Medical Monitor or Investigator. 
The number and percentage of patients reporting TEAEs by cohort will be 
tabulated by system organ class and preferred term; by system organ class, 
preferred term, and severity; and by system organ class, preferred term, and 
relationship to the investigational product.  If more than 1 AE is coded to the 
same preferred term for the same patient, the patient will be counted only once for 
that preferred term using the most severe and most related occurrence for the 
summarization by severity and by relationship to the investigational product. 
Listings will be presented for patients with SAEs and patients with AEs leading to 
discontinuation.  A listing of all AEs by patient will also be presented. 
10.9.2 Clinical Laboratory Parameters 
Descriptive statistics for clinical laboratory values and changes from the baseline 
values will be presented by cohort for each clinical laboratory parameter. 
The number and percentage of patients who have post-baseline potentially 
clinically significant (PCS) clinical laboratory values will be tabulated by cohort.  
The criteria for PCS laboratory values will be detailed in the SAP.  The 
percentages will be calculated relative to the number of patients who have 
available non-PCS baseline values and at least 1 post-baseline assessment.  The 
numerator will be the total number of patients with available non-PCS baseline 
values and at least 1 post-baseline PCS value.  A supportive listing of patients 
with post-baseline PCS values will be provided, including the patient number and 
baseline and post-baseline values by cohort for the Safety Population. 
Urinalysis and Coagulation results will be listed by patient.

10.9.3 ECOG 
Descriptive statistics for ECOG performance at baseline (pre-study) and changes 
from pre-study to End-of-Study will be presented by cohort.   
10.9.4 Vital Signs 
Descriptive statistics for vital signs (systolic and diastolic BP, pulse rate, weight, 
respiration rate, and temperature) at baseline (pre-study) and changes from pre-
study to End-of-Study will be presented by cohort.  Descriptive statistics for 
interim vital signs (systolic and diastolic BP, pulse rate) during the PK profiling 
period (time between first dose of investigational product and the End-of-Study) 
at baseline (pre-dose) and changes from baseline at post-dose will be presented by 
cohort. 
Vital sign values will be considered to be PCS if they meet both the observed 
value criteria and the change from baseline value criteria that will be detailed in 
the SAP. The incidence of PCS values will be presented. The percentages will be 
calculated relative to the number of patients who have baseline values and at least 
1 post-baseline assessment.  The numerator will be the total number of patients 
with at least 1 PCS post-baseline value. For the Safety Population, a supportive 
listing of patients with PCS post-baseline values will be provided, including the 
patient number and baseline and post-baseline values, by cohort for pre-Study and 
End-of-Study assessments and by treatment for assessments during the PK 
profiling period. 
10.9.5 Electrocardiograms 
Descriptive statistics for ECG parameters (HR, PR interval, QRS duration, 
QT interval, and QTc) will be reported. 
10.9.6 Physical Examination 
Individual data listings for physical examination results will be presented for each 
subject. 
10.9.7 Weight and Height 
Weight, height, BMI and BSA will be listed and summarized by cohort. 
10.9.8 Prior and Concomitant Medication 
Prior medication will be defined as any medication taken within 14 days prior to 
the first dose of the study drug and stopped prior to the first dose of study drug.   
Concomitant medication will be defined as any medication taken during the study 
between the date of the first dose of study drug and the date of the End-of-Study 
Visit.  Any medications started after the End-of-Study Visit will not be considered 
concomitant medications.

CHANGES IN THE CONDUCT OF THE STUDY OR PLANNED ANALYSES 
If any amendments to this protocol are necessary, the Sponsor will propose them in 
writing to the Investigator.  Any amendments proposed by the Investigator will be 
reviewed and approved by the Sponsor prior to submission for IRB review and 
implementation.  No protocol amendment may be implemented (with the exceptions 
noted below) before it has been submitted to the Regulatory Agency and approved by the 
Institutional Review Board (IRB)/Independent Ethics Committee (IEC).  In addition the 
Investigator signature page must be signed and submitted to the Sponsor. 
If the protocol is amended to eliminate or reduce the risk to patients, the amendment may 
be implemented before IRB/IEC review and approval.  However, the IRB/IEC must be 
informed in writing of such an amendment, and approval must be obtained within 
reasonable time limits. 
Protocol waivers will be allowed only in extremely rare circumstances where patient 
benefit is established and there is complete agreement between the Investigator and the 
Sponsor. 
Protocol deviations brought to the attention of the Sponsor after their occurrence will 
only be recognized and assessed for ethical, medical, scientific, and regulatory 
implications and for impact on the patient’s participation in the study, and will be 
documented.  Such deviations cannot be waived. 
Protocol violations (which are deviations that have a major impact on the patient’s rights, 
safety, or well-being or the integrity and authenticity of the study data) can never be 
waived.

Independent Ethics Committee / Institutional Review Board  
It is the responsibility of the Investigator to obtain the approval of the IEC / IRB 
before the start of the study. A copy of the approval letter will be supplied to the 
Sponsor, along with a roster of IEC / IRB members.  During the course of the 
study, the Investigator or designee will provide timely and accurate reports to the 
IEC / IRB on the progress of the study at appropriate intervals (not to exceed 
1 year) and at the completion of the study.  Investigator or designee will notify the 
IEC / IRB of serious AEs (SAEs) or other important safety findings.  The study 
protocol, informed consent form (ICF), information sheet advertisements (if any), 
and amendments (if any) will be approved by the IRB at each study center in 
conformance CFR, Title 21, Part 56.  
12.2 
Patient Information and Consent 
Before the start of any study-related procedures are undertaken, the Investigator 
or designee must obtain written, informed consent from each patient  in 
accordance with US federal regulations (21 CFR §50) and the ICH document 
“Guidance for Industry – E6 Good Clinical Practice: Consolidated Guidance”.  
Informed consent will be obtained by discussing with the patient the purpose of 
the study, the risks and benefits, the study procedures, and any other information 
relevant to the patient. 
The Investigator or designee must explain to the patient that for purposes of 
evaluating the study results, that patient’s private health information obtained 
during the study may be shared with the Sponsor, regulatory agencies, and IECs / 
IRBs, before enrolling that patient into the study.  It is the US Investigator’s (or 
designee’s) responsibility to obtain permission to use private health information 
per the Health Information Portability and Accountability Act (HIPAA) from each 
patient, or if appropriate, the patient’s legal representative. 
The patient or his/her legal representative will document his/her informed consent 
by signing the current version of the written, IRB-approved ICF.  The person who 
conducted the informed consent discussion with the patient and/or patient’s legal 
representative (if applicable) must also sign the ICF. The patient is given a fully 
executed copy of the ICF bearing all appropriate signatures, and the original must 
be maintained in the clinical master files at the site.

13.4 
Data Recording and Documentation 
Data collection will involve the use of the Sponsor EDC system, to which only 
authorized personnel will have access.  In addition to periodic monitoring 
occurring within the system by Sponsor personnel, programmatic edit checks will 
be used to review the data for completeness, logic, and adherence to study 
protocol.  As a result of this monitoring and these checks, queries may be issued 
electronically to the clinical study center and answered electronically by that 
study center.  The identifying information (assigned username, date, and time) for 
both the originator of the query (if created during the monitoring process) and the 
originator of the data change (if applicable), as well as the Investigator’s approval 
of all changes performed on his or her patients’ data, will be collected. 
All data collected in the context of this study will be stored and evaluated 
according to regulatory requirements and applicable guidance for electronic 
records.  Data will be stored and evaluated in such a way as to guarantee patient 
confidentiality in accordance with the legal stipulations applying to 
confidentiality of data.  Study records (e.g., copies of eCRFs, regulatory 
documents, etc.) will be retained at the study center, along with adequate source 
documentation, according to FDA and ICH requirements.  All study records must 
be available for inspection by the Sponsor, its authorized representatives, and 
FDA officials. 
13.5 
Retention and Review of Records 
The PI must maintain the documentation relating to this study.  If the Sponsor, the 
FDA, or another regulatory authority wishes to review any documentation relating 
to the study, the PI must permit access to such records. 
The PI must retain a copy of all records that support the CRFs for this study (e.g., 
ICFs, clinical laboratory reports, source documents, investigational product 
dispensing records) for a period of at least 15 years after study completion unless 
local regulations or study center policies require a longer retention period or 
otherwise notified in writing by the Sponsor.  
If the PI retires, relocates, or for other reasons withdraws from the responsibility 
of keeping the study records, custody must be transferred to a suitable alternate 
custodian employee of the study center or to a suitably qualified and responsible 
third party.  The Sponsor must be notified in writing of the name and address of 
the new custodian before such transfer is made.  
No study records shall be destroyed without notifying and giving the Sponsor the 
opportunity to arrange long-term storage for such study records or to authorize in 
writing the destruction of records after the required retention period.
