1 SYNOPSIS 
Title of Study: 
A Randomized, Open-Label, Two-Treatment, Two-Period, Two-Way Crossover Study to 
Investigate the Bioequivalence of Entrectinib Polymorph Forms A and C under Fasted 
Conditions in Healthy Subjects 
Objectives: 
The primary objective of this study is: 
• 
To demonstrate bioequivalence between entrectinib polymorph Forms A and C 
under fasted conditions in healthy adult male and female subjects 
The secondary objective of this study is: 
• 
To explore the safety and tolerability of a single 200-mg oral dose of entrectinib 
polymorph Forms A and C in healthy adult male and female subjects 
Methodology/Study 
Design: 
This is a randomized, open-label, 2-treatment, 2-period, 2-way crossover study to 
demonstrate bioequivalence between entrectinib polymorph Forms A and C administered 
under fasted conditions in healthy male and female subjects. Potential subjects will be 
screened to assess their eligibility to enter the study within 27 days (Days -28 to -2) prior 
to study entry. Dosing will be on Day 1 of each period. Replacement subjects may be 
enrolled, only if deemed necessary by the Sponsor. Samples will be collected for analysis 
at specified timepoints. 
Number and General 
Description of Subjects: 
A total of 28 subjects will be enrolled in the study at a single clinical site to complete a 
minimum of 26 subjects. 
Diagnosis and Main 
Criteria for Inclusion: 
Healthy males and females, between 18 and 60 years of age, inclusive, within body mass 
index range of 18.0 to 32.0 kg/m2, inclusive, weighing at least 50 kg at Screening who 
are in good health, as determined by no clinically significant findings from medical 
history, 12-lead electrocardiogram (ECG), clinical laboratory evaluations, and vital 
signs. 
Test Product(s), Dose, 
and Mode of 
Administration: 
Subjects will receive the following 2 treatments in a randomized sequence. Each 
treatment will be dosed as 1 × 200-mg capsule administered orally with 240 mL of water 
after an overnight fast (minimum 8 hours): 
• 
Single 200-mg oral dose of entrectinib F06 capsule formulation Form A 
(Reference formulation) 
• 
Single 200-mg oral dose of entrectinib F06 capsule formulation Form C (Test 
formulation) 
Duration of Treatment: 
Planned Enrollment/Screening Duration:  approximately 4 weeks. 
Length of Each Confinement:  Subjects will be confined at the study site from the time of 
Check-in (Day -1) of each period until Clinic Discharge on Day 5. There will be at least 
a 14-day washout between doses in Periods 1 and 2. There will be a follow-up telephone 
call 12 to 14 days after the last dose of study drug (Period 2). 
Planned Study Conduct Duration:  approximately 8 weeks. 
Criteria for Evaluation:  
Safety 
Safety and tolerability assessments will include recording of adverse events, clinical 
laboratory evaluations, vital sign measurements, physical examinations, and ECGs. 
Criteria for Evaluation:  
Pharmacokinetics 
The following pharmacokinetic (PK) parameters will be derived from the plasma 
concentrations of entrectinib and M5 using the model independent approach:  maximum 
observed concentration (Cmax), time to maximum observed concentration (tmax), area 
under the concentration-time curve from Hour 0 to the last measurable concentration 
(AUC0-t), area under the concentration-time curve extrapolated to infinity (AUC0-∞), 
apparent terminal elimination rate constant (λz), apparent terminal elimination half-life 
(t1/2), apparent systemic clearance (entrectinib only, CL/F), and apparent volume of 
distribution during the terminal elimination phase (entrectinib only, Vz/F). 
Statistical Methods: 
Descriptive statistics (mean, median, minimum, maximum, standard deviation, geometric 
mean, and geometric coefficient of variation) will be calculated for all PK parameters 
and PK concentration data. 
The primary parameters for bioequivalence testing will be Cmax and AUC0-t of

entrectinib. A linear mixed model will be applied to analyze the log-transformed primary 
PK parameters. The model assumes fixed effects for treatment, period, and sequence, and 
a random effect for subject within sequence. Estimates of geometric mean ratios on the 
original scale, together with the corresponding 90% confidence intervals (CIs), will be 
derived for the comparisons between Test and Reference treatments. Bioequivalence will 
be concluded if the 90% CIs for the treatment ratios fall within the no-effect boundaries 
of 0.80 and 1.25. 
Descriptive statistics will be calculated on the safety parameters. No formal statistical 
analyses are planned.

2 INTRODUCTION 
2.1 BACKGROUND 
Entrectinib (RO7102122, formerly known as RXDX-101) is a potent and selective inhibitor of 
TRKA, TRKB, TRKC, ROS1, and ALK receptor tyrosine kinase. These kinases are 
overexpressed or dysregulated in a number of types of cancer with constitutive activity, making 
the growth of the cancer cells dependent on or “addicted” to the abnormal kinases.1,2 Therefore, 
these kinases represent attractive targets for anticancer therapy. 
 
Refer to the Investigator’s Brochure (IB)3 for detailed background information on entrectinib and 
for details on nonclinical and clinical studies. 
2.1.1 PHARMACOLOGY 
Entrectinib selectively inhibits TRKA/B/C, ROS1, and ALK tyrosine kinases at low nanomolar 
concentrations in vitro and is highly potent in inhibiting proliferation of tumor cell lines 
dependent on the expression of these kinases. Treatment of mice bearing different xenograft 
(TRKA- or ALK-dependent) or allograph (ROS1-dependent) tumors with 60 mg/kg entrectinib 
twice daily showed potent growth inhibition of TRKA-dependent tumors and even complete 
regression of ROS1- and ALK-dependent tumors. 
2.1.2 TOXICOLOGY AND SAFETY PHARMACOLOGY 
In in vivo toxicology studies, adverse findings were observed in the skin, liver, central nervous 
system (CNS), and hemolymphopoietic system of both rats and dogs, while gastrointestinal (GI) 
toxicity was also observed in dogs. These effects were dose- and exposure-dependent, and 
exhibited reversibility. Central and peripheral neurologic events were common, consistent with 
penetration of entrectinib into the CNS and the role of TRK receptors in neuronal development 
and maintenance; signs included incoordination, decreased activity, staggering, abnormal gait, 
tremors, hypoactivity, and depression. In Good Laboratory Practices repeat-dose studies, no 
observed adverse effect levels were 7.5 mg/kg/day in rats and 15 mg/kg/day in dogs. 
 
Entrectinib inhibited human ether-à go-go-related gene tail current in vitro with a half-maximal 
inhibitory concentration of 0.6 μM as free drug (approximating to 120 μM after correction for 
plasma protein binding in humans). In in vivo preclinical studies, moderate but reversible 
prolongation of the QT interval corrected for heart rate (QTc) was noted on electrocardiograms 
(ECGs) at high doses in dogs.

Entrectinib was not mutagenic or clastogenic in in vitro or in vivo genotoxicity studies. There 
was no evidence of adverse effects on reproductive organs in repeat-dose toxicology studies. In 
an embryo-fetal developmental study, oral administration of entrectinib to pregnant rats during 
organogenesis caused developmental abnormalities at dose levels that also caused maternal 
toxicity. 
 
Entrectinib is not phototoxic based on results from an in vivo rat study. However, microscopic 
findings in rats of neutrophil infiltrates of corneal stroma and single cell necrosis of the corneal 
epithelium at high doses were considered entrectinib-related. 
2.1.3 PHARMACOKINETICS 
Entrectinib is readily absorbed following oral administration with reasonable oral bioavailability 
(31% to 76% in preclinical species) and with peak concentrations typically occurring 
approximately 4 hours after dosing (Figure 1). Entrectinib exposure is dose proportional, with no 
significant dose- or time-dependency. The terminal half-life of entrectinib is approximately 20 to 
30 hours. 
 
Food has no significant effect on oral bioavailability from clinical capsule formulations 
containing acidulant (Figure 1).

Entrectinib is highly protein bound (≥99%) and has a high apparent volume of distribution 
(approximately 600 L), indicating extensive distribution into body tissues. Data also suggest that 
entrectinib crosses the blood/brain barrier. 
 
Entrectinib is primarily cleared by metabolism, with the majority of a dose being recovered as 
metabolites in feces and very little elimination of parent drug or metabolites via the kidney. 
Based on in vitro incubations, cytochrome P450 (CYP) 3A4 is the primary enzyme responsible 
for the biotransformation of entrectinib, with lesser contributions from other CYPs and Phase II 
enzymes. The M5 metabolite (formed by demethylation) is a major circulating metabolite and is 
also pharmacologically active. 
 
In in vitro drug-drug interaction studies entrectinib exhibited potential to inhibit and induce the 
activities of CYP3A. A study on the interaction with transporters in vitro revealed that 
entrectinib is a poor P-glycoprotein (P-gp) substrate and has the potential to inhibit the 
transporters P-gp (MDR1), breast cancer resistance protein, and MATE1. 
2.1.4 CLINICAL PROGRAM 
The clinical program to date includes 10 healthy volunteer and 5 patient studies:  approximately 
300 healthy volunteers and approximately 400 patients have received one or more doses of 
entrectinib. In patients with NTRK, ROS1, or ALK fusion-positive locally advanced or 
metastatic extracranial solid tumors, antitumor activity has been broadly observed among TRK, 
ROS1, and ALK inhibitor-naïve patients treated with entrectinib, including patients with CNS 
involvement. Based upon particularly compelling clinical safety and efficacy data and an 
assessment of unmet medical need, entrectinib development has focused on 2 patient 
populations, NTRK fusion-positive solid tumors and ROS1 fusion-positive non-small cell lung 
cancer. 
 
In the 4 main entrectinib studies in oncology patients, the most common treatment-related 
adverse events (AEs) were dysgeusia (39%), fatigue (31%), dizziness (23%), constipation (22%), 
diarrhea (19%), nausea (19%), paresthesia (17%), weight increased (17%), blood creatinine 
increased (14%), myalgia (14%), vomiting (12%), peripheral edema (12%), anemia (11%), and 
arthralgia (10%). All AEs were reversible with dose modifications, and there was no evidence of 
cumulative toxicity, clinically significant hepatic toxicity, or clinically significant QTc 
prolongation. In single-dose clinical pharmacology studies, entrectinib doses up to 800 mg have 
been administered to healthy volunteers without significant safety findings.

2.2 STUDY RATIONALE 
Entrectinib can exist in 2 polymorphic forms (Forms A and C). 
 
 
 
 
 
 
 
 
 
 Therefore, the principal aim of this study is to compare the 
in vivo pharmacokinetic (PK) performance of 2 capsule formulations containing either 
polymorph Form A or C, 
 
 
2.3 DOSE RATIONALE 
The recommended dose of entrectinib for cancer patients is 600 mg once daily administered as 
3 × 200-mg capsules, and so a single-capsule dose of 200 mg is used for the current study. Single 
doses of entrectinib up to 800 mg have been administered to healthy volunteers in previous 
clinical pharmacology studies without notable safety or tolerability findings. 
2.4 BENEFIT:RISK ASSESSMENT 
There will be no therapeutic benefit for the healthy subjects participating in the study. 
 
The risks of participation are primarily those associated with adverse reactions to the study drug, 
although there may also be some discomfort from collection of blood samples and other study 
procedures. The tolerability profile of entrectinib from administration of single doses to healthy 
subjects has been characterized from previous clinical studies. There have been few AEs 
following entrectinib dosing in previous clinical studies in healthy volunteers and no specific 
safety concerns have been identified about the use of entrectinib in healthy volunteers. Of the 
potential risks identified in the IB, none require specific monitoring or risk mitigation 
procedures. Potential drug-drug interactions with other medications are addressed by restrictions 
on concomitant medication use. Potential risks to a developing fetus from entrectinib exposure in 
utero are addressed by exclusion of pregnant females from the study and the requirement for all 
participants to use effective contraception throughout the study.

Overall, no significant safety concerns have been identified about the use of 200 mg entrectinib 
in healthy subjects. All subjects will be resident in the study center and remain under medical 
supervision following each study drug administration and will undergo a standard battery of 
safety assessments. Hence, the risks to participants in this study are considered acceptable. 
3 STUDY OBJECTIVES AND CORRESPONDING ENDPOINTS 
3.1 PRIMARY OBJECTIVE 
The primary objective of this study is: 
• To demonstrate bioequivalence between entrectinib polymorph Forms A and C under 
fasted conditions in healthy adult male and female subjects 
3.2 SECONDARY OBJECTIVE 
The secondary objective of this study is: 
• To explore the safety and tolerability of a single 200-mg oral dose of entrectinib 
polymorph Forms A and C in healthy adult male and female subjects 
3.3 PRIMARY ENDPOINTS 
The primary endpoints are: 
• The geometric mean ratios and associated 90% confidence intervals (CIs) of entrectinib 
and M5 metabolite PK parameters area under the concentration-time curve from Hour 0 
to the last measureable concentration (AUC0-t) and maximum observed concentration 
(Cmax) 
3.4 SECONDARY ENDPOINTS 
The secondary endpoints are: 
• Incidence and severity of AEs and incidence of abnormalities in laboratory safety tests, 
12-lead ECGs, and vital sign measurements 
4 STUDY DESIGN 
4.1 DESCRIPTION OF THE STUDY 
This is a randomized, open-label, 2-treatment, 2-period, 2-way crossover study to demonstrate 
bioequivalence between entrectinib polymorph Forms A and C administered under fasted 
conditions in healthy male and female subjects. In each treatment period, subjects will receive a

Protocol GP41049 
 
 
Final:  5 November 2018 
Page 19 of 62 
CPET Protocol Template, Version 11.0:  30 April 2018 
Subjects will be confined at the study site from the time of Check-in (Day -1) of each period 
until Clinic Discharge on Day 5 in each period. The site will attempt to contact all subjects who 
received at least 1 dose of entrectinib (including subjects who terminate the study early) 
approximately 12 to 14 days after the last study drug administration. A detailed list of 
assessments to be conducted in this study is included in Table 7-1. 
 
In this study, physical examinations, 12-lead ECGs, vital signs, How do you feel? (HDYF?) 
inquiries, and clinical laboratory evaluations (Appendix A) will be performed at specified times 
during the study (for specific timepoints and details on each study variable, refer to Section 7). 
After informed consent has been obtained but prior to initiation of study drug administration, 
only serious AEs (SAEs) caused by protocol-mandated interventions will be reported. After 
study drug administration on Day 1 of Period 1, all AEs, whether volunteered, elicited, or noted 
upon physical examination, will be recorded throughout the study (i.e., from Day 1 of Period 1 
until Early Termination [ET] or until the follow-up telephone call). A schedule of activities is 
presented in Table 7-1. 
 
The end of study is defined as the date of the last scheduled study procedure for the last 
participating subject. 
4.2 RATIONALE FOR STUDY DESIGN 
A crossover design will be used to reduce the residual variability as every subject acts as their 
own control. A single-dose, crossover design is the standard design to compare PK. Subjects will 
be randomized to 1 of 2 treatment sequences to minimize assignment bias. 
 
This study is an open-label investigation because the PK parameters are believed not to be 
subject to bias. The crossover design further minimizes the effect of inter-subject variability. 
Blood sampling up to 96 hours postdose will allow the PK parameters of entrectinib and 
metabolite M5 to be adequately characterized based on prior data. The 14-day washout between 
entrectinib doses is considered sufficient to prevent carryover effects of the treatments based on 
the entrectinib apparent terminal elimination half-life (t1/2) of approximately 20 to 30 hours and 
M5 t1/2 of approximately 40 hours. 
 
Doses will be administered in the fasted state for formulation comparison without the 
confounding effect of food.

4.3 RATIONALE FOR SUBJECT POPULATION 
Healthy adult male and female subjects were chosen for inclusion in this study because they are 
free of health problems that could otherwise make them more susceptible to drug toxicity or 
confound the interpretation of the study results, are not routinely using concomitant medications 
that could interact with the study drug, and can provide a standard basis for comparison 
(i.e., control) with less variability. 
4.4 RATIONALE FOR EXPLORATORY ASSESSMENTS 
Not applicable. 
4.5 RATIONALE FOR PHARMACOKINETIC SAMPLING SCHEDULE 
The PK sampling schedule has been selected on the basis of data from previous studies in which 
a single dose of entrectinib was administered to healthy volunteers. The frequent sampling 
schedule is designed to capture data at a sufficient number of timepoints to provide a detailed 
profile of the concentration-time curve, including Cmax, time to maximum observed concentration 
(tmax), and t1/2. 
5 SUBJECT SELECTION 
A total of 28 healthy volunteer male and female subjects who meet all the protocol inclusion 
criteria and none of the exclusion criteria will be enrolled into the study. 
5.1 SCREENING PROCEDURES 
Refer to Table 7-1 for procedures performed for all potential subjects at the Screening visit. 
5.2 CHECK-IN PROCEDURES 
Refer to Table 7-1 for procedures performed at Check-in (Day -1), when subjects will report to 
the study site. 
 
For subjects to continue their participation in the study, the drug and alcohol (as applicable) 
screen (and for females of childbearing potential, the pregnancy test) must be negative and the 
clinical laboratory evaluations must be within the normal laboratory range (unless deemed not 
clinically significant by the Investigator). In addition, continued compliance with concomitant 
medication and other restrictions will be verified.

illness within 4 weeks prior to Screening, or clinically significant acute infection or 
febrile illness within 14 days prior to Screening; 
6. Any other ongoing condition, disease, or laboratory test result that the Investigator 
considers would render the subject unsuitable for the study, place the subject at undue 
risk, interfere with the ability of the subject to participate in or complete the study, or 
confound interpretation of study data; 
7. Use of moderate or potent inhibitors or inducers of CYP3A enzyme or the transporter 
P-gp within 28 days prior to Screening and during the entire study duration, or use of 
other prohibited medications within 14 days prior to Screening and during the entire 
study duration (see Section 7.6); 
8. Participation in any other clinical study involving an investigational medicinal product 
(IMP) or device within 30 days or 5 half-lives (if known), whichever is longer, before 
Screening;

or related compounds; 
11. Poor peripheral venous access; 
12. Donation or loss of over 500 mL of blood or donation of plasma from 3 months prior to 
Screening through Follow-up; 
13. Receipt of blood products within 2 months prior to Check-in (Day -1) of Period 1. 
5.5 REMOVAL OF SUBJECTS FROM STUDY PARTICIPATION 
Subjects will be informed that they are free to withdraw from the study at any time and for any 
reason. The Investigator may remove a subject from the study if, in the Investigator’s opinion, it 
is not in the best interest of the subject to continue the study. Subjects may be discontinued due 
to the following:  change in compliance with inclusion/exclusion criterion that is clinically 
relevant and affects subject safety, occurrence of AEs, occurrence of pregnancy, intake of

non-permitted concomitant medication that might affect subject safety or study 
assessments/objectives, etc. Notification of discontinuation will immediately be made to the 
Sponsor’s Study Monitor. In case of premature discontinuation of study participation, efforts will 
be made to perform all final study day assessments (see Section 7.15). The date the subject is 
withdrawn from the study and the reason for discontinuation will be recorded on the subject’s 
electronic Case Report Form (eCRF). All dropouts will be followed until resolution of all their 
AEs or until the unresolved AEs are judged by the Investigator to have stabilized or returned to 
baseline, as applicable. 
 
For subjects who are discontinued by the Investigator or who voluntarily withdraw prematurely 
from the study, replacement subjects will be enrolled only if deemed necessary by the Sponsor. 
Except for replacements, the subjects will be assigned a number by study site staff. Assignment 
of numbers will be in ascending order and no numbers will be omitted. Subject numbers will be 
used on all study documentation. Replacement subjects will be assigned a subject number by 
adding 100 or 1000 to the number of the subject they are replacing (e.g., Subject No. 105 
replaces Subject No. 005). 
 
The entire study may be discontinued at the discretion of the Investigator, Sponsor, or Sponsor’s 
Medical Monitor based on the occurrence of the following: 
• 
AEs unknown to date with respect to their nature, severity, and duration 
• 
Increased frequency, and/or severity, and/or duration of known AEs 
• 
Medical or ethical reasons affecting the continued performance of the 
study 
• 
Difficulties in the recruitment of subjects 
• 
Cancellation of drug development 
6 ASSESSMENT OF SAFETY 
Subjects will undergo safety monitoring during the study, including assessment of the nature, 
frequency, and severity of AEs throughout the study, and clinical laboratory safety testing and 
measurement of ECGs and vital signs at intervals.

a Specific ingredients/purity will be identified on the Certificate of Analysis (or equivalent) that is supplied with the 
study drug(s). 
 
The lot numbers for the study drugs will be provided to the study site by the 
supplier/manufacturer as soon as available. 
 
Study drugs will be stored at controlled room temperature (not above 25°C) under secure 
conditions. The study drugs will be transferred from the bulk supplies into the subject’s dose 
container by qualified study site employees. Each unit dose container will be appropriately 
labeled. 
 
The Investigator or designee will maintain an accurate record of the receipt of the test materials 
as shipped by the Sponsor or designee, including the date received. One copy of this receipt will 
be returned to the Sponsor when the contents of the test material shipment have been verified. In 
addition, an accurate drug disposition record will be kept, specifying the amount dispensed to 
each subject and the date of dispensation. This drug accountability record will be available for 
inspection at any time. At the completion of the study, the original drug accountability record 
will be available for review by the Sponsor upon request. 
 
If deemed appropriate by the Sponsor, sufficient samples will be randomly selected from the 
supply provided by the Sponsor or designee and retained by the study site to meet the retention 
requirements described in the United States (US) Title 21 Code of Federal Regulations (CFR) 
320.38 and 320.63. 
 
At the completion of the study, all unused drug supplies (except for retention supplies, if 
appropriate) will be returned to the Sponsor or designee or disposed of by the study site, per the 
Sponsor’s or designee’s written instructions. 
7.2.2 DOSE PREPARATION AND ADMINISTRATION 
Each unit dose will be prepared by qualified clinical staff based on the study randomization that 
will be provided by a Covance Biostatistician. 
 
The assigned treatment will be administered on Day 1 of each period:

Treatment A: Entrectinib F06 capsule formulation Form A (Reference formulation) 
Treatment C: Entrectinib F06 capsule formulation Form C (Test formulation) 
 
Each dose will be administered orally with approximately 240 mL of room temperature water 
after an overnight fast (minimum 8 hours). A hand and mouth check will be performed to verify 
that the dose administered was swallowed. Subjects will be instructed not to crush, split, or chew 
the entrectinib capsules. Subjects will continue to fast for at least 4 hours following entrectinib 
dosing. 
 
Water (except water provided with entrectinib dosing) will be restricted 1 hour prior to and 
1 hour after each entrectinib administration, but will be allowed ad libitum at all other times. 
 
Doses of entrectinib will be separated by a washout period of at least 14 days. 
 
Appropriate unit doses, as described above, will be administered to consecutively numbered 
subjects. Although the timing of events requires that each subject will be consistently 
administered the appropriate dose at specific times, the exact dose time of consecutive subjects 
may be staggered to obviate the need to have all subjects on precisely the same study schedule. 
For each dose, the subject’s actual time will be recorded in the source documents and transcribed 
into the eCRFs. 
7.3 REMOVAL OF STUDY BLIND 
Not applicable; this is an open-label study and will not be blinded. 
7.4 CONTRACEPTION 
Postmenopausal is defined as at least 12 months without a period (i.e., amenorrhea) in a female 
at least 45 years of age and documented by a serum follicle-stimulating hormone [FSH] level 
consistent with postmenopausal status (i.e., ≥40 IU/L) in the absence of a reversible medical 
iatrogenic cause. Surgically sterile is defined as permanently sterile via hysterectomy, bilateral 
oophorectomy, and/or bilateral salpingectomy by reported medical history and/or medical 
records for at least 90 days prior to Screening. 
 
Females who are not postmenopausal or surgically sterile are of childbearing potential and must 
agree to use one of the following examples of highly-effective contraception (failure rate of <1% 
per year) from the time of signing the informed consent or 10 days prior to Check-in (Day -1) of

• Bilateral tubal ligation 
• Bilateral tubal occlusion (Essure) 
• Vasectomized male partner 
• Hormonal contraceptives that inhibit ovulation 
• Hormone-releasing intrauterine device (IUD) 
• Copper IUD 
 
Male subjects will either be surgically sterile with documented azoospermia (confirmed by 
reported medical history and/or medical records) for at least 90 days prior to Screening, or will 
be required to use the following approved method of contraception from Check-in (Day -1) of 
Period 1 and for 90 days after the final dose of study drug: 
• Male condom with spermicide 
 
For subjects who are exclusively in same-sex relationships or are abstinent (when this is in line 
with the preferred and usual lifestyle of the subject), contraceptive requirements do not apply. If 
a subject who is in a same-sex relationship or abstinent at the time of signing the ICF becomes 
engaged in a heterosexual relationship, they must agree to use contraception, as described 
previously. 
 
Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and 
withdrawal are not acceptable methods of contraception. If a male subject cannot provide proof 
of sterilization by medical records, the subject must agree to either true abstinence or a method 
of birth control, as outlined above. 
 
Male subjects (including men who have had vasectomies) whose partners are currently pregnant 
should use a barrier method with spermicide for the duration of the study through Follow-up. 
This is to ensure that the fetus is not exposed to the drug in the ejaculate. 
7.5 DIET, FLUID, AND ACTIVITY CONTROL 
Subjects will refrain from use of tobacco- or nicotine-containing products (including, but not 
limited to, cigarettes, e-cigarettes, pipes, cigars, chewing tobacco, nicotine patches, nicotine 
lozenges, and nicotine gum) within 6 months prior to Check-in (Day -1) of Period 1 and during 
the entire study. 
 
Subjects will abstain from consuming alcohol- or caffeine-containing foods and beverages for 
72 hours prior to Check-in (Day -1) of Period 1 and during the entire study, unless deemed 
acceptable by the Investigator.

Subjects will abstain from consuming grapefruit- or Seville orange-containing foods and 
beverages for 7 days prior to Check-in (Day -1) of Period 1 and during the entire study, unless 
deemed acceptable by the Investigator. 
 
Subjects will refrain from strenuous exercise from 48 hours prior to Check-in (Day -1) of 
Period 1 and during the period of confinement at the study site and will otherwise maintain their 
normal level of physical activity throughout the entire study (i.e., will not begin a new exercise 
program or participate in any unusually strenuous physical exertion). 
 
With the exception of dosing, as applicable, while confined at the study site, subjects will receive 
a standardized diet at scheduled times that do not conflict with other study-related activities. 
 
See Section 7.2.2 for diet and fluid restrictions in regards to dose administration. 
 
Subjects will remain ambulatory or seated upright for 4 hours following entrectinib 
administration, except as necessitated by the occurrence of an AE(s) and/or study procedures. 
7.6 CONCOMITANT MEDICATIONS 
Subjects should not take any prescription or over-the-counter medication, vitamins, or minerals 
from 14 days prior to Screening and during the study, unless the Investigator has given prior 
consent. The following categories of medication are specifically prohibited from 28 days prior to 
Screening and during the study: 
• Moderate or potent inhibitors or inducers of CYP3A enzyme or P-gp transporter 
• Gastric pH-modifying agents such as proton pump inhibitors, H2 receptor antagonists, 
and antacids 
• Psychoactive drugs or other drugs used for mental disorders. Examples include 
anti-depressants, anti-psychotics, sedatives, and stimulants 
 
Acetaminophen (paracetamol) up to 2 g per day, medications to treat AEs, hormonal 
contraceptives, and hormone replacement therapy are allowed throughout the study. Ondansetron 
is permitted as a treatment for nausea for individual subjects at the discretion of the Investigator. 
Other medications for chronic, non-clinically significant conditions (e.g., thyroid hormone 
replacement medication) may be permitted providing the subject has been on a stable dose and 
dosing regimen for at least 3 months prior to Screening.

CPET Protocol Template, Version 11.0:  30 April 2018 
The administration of any other concomitant medications during the study is prohibited without 
prior approval of the Investigator, unless its use is deemed necessary in a medical emergency. 
Any medication taken by a subject during the course of the study, including the name, strength, 
frequency of dosing, and reason for its use, will be documented in the source documents and the 
eCRF. 
7.7 PHARMACOKINETIC BLOOD SAMPLE COLLECTION AND PROCESSING 
Blood samples for PK analysis of entrectinib and M5 levels will be collected via an indwelling 
catheter and/or via direct venipuncture using Vacutainer or equivalent evacuated collection 
tubes. Blood samples will be collected at the timepoints listed in Table 7-2. 
 
Processing, storage, and shipping instructions for these PK blood samples are presented in a 
separate laboratory manual. 
 
After the plasma samples collected in the study are analyzed for entrectinib and M5 
concentrations, any residual samples may be used for analysis such as metabolite profiling and 
identification, interacting drug concentration measurements, ex vivo protein binding, or 
development of PK or pharmacodynamic assays. Residual PK samples will be destroyed no later 
than 5 years after the final Clinical Study Report (CSR) has been completed. When a subject 
withdraws from the study, samples collected prior to the date of withdrawal may still be 
analyzed, unless the subject specifically requests in writing that the samples be destroyed or local 
laws require destruction of the samples. However, if samples have been tested prior to 
withdrawal, results from those tests will remain as part of the overall research data. Sample 
retention may be detailed in the laboratory manual. 
7.8 ANALYTICAL METHODOLOGY 
Plasma concentrations of entrectinib and M5 will be determined using a validated liquid 
chromatography tandem mass spectrometry bioanalytical procedure by an external vendor. 
7.9 CLINICAL LABORATORY EVALUATIONS 
Clinical laboratory evaluations (including chemistry panel [fasted at least 8 hours], CBC, and 
UA) will be collected at the timepoints listed in Table 7-1. 
 
Screens for a hepatitis panel and HIV antibody will be performed at Screening. A drug screen for 
selected drugs of abuse (not including alcohol) will be performed at Screening and repeated (but 
including an alcohol breath test) at Check-in (Day -1). A serum qualitative pregnancy test

(females of childbearing potential only) and FSH test (postmenopausal females only) will be 
performed at the timepoints specified in Table 7-1. 
7.10 
12-LEAD ELECTROCARDIOGRAMS 
A single 12-lead ECG will be obtained at the timepoints specified in Table 7-1. 
 
To minimize variability in autonomic tone and heart rate, subjects will rest quietly and in a 
supine position for at least 5 minutes prior to recording the ECG. Blood draws, other procedures, 
activity, and environmental distractions (e.g., television, radio, conversation) should be avoided 
during the pre-ECG resting period and between ECG recordings to minimize variability due to 
the effects of activity and stress on cardiac electrophysiology. Whenever possible, ECG tracings 
for each subject should be obtained from the same type of machine throughout the study. 
 
When 12-lead ECGs are scheduled at the same time as blood draws, the blood draws will be 
obtained at the scheduled timepoint, and the 12-lead ECGs will be obtained as close as possible 
to the scheduled blood draw, but prior to the blood draw. 
7.11 
VITAL SIGNS 
Vital signs (including oral temperature, respiratory rate, and supine blood pressure and pulse 
rate) will be obtained at the timepoints specified in Table 7-1. 
 
Supine blood pressure and pulse rate will be obtained after the subject has been supine for at 
least 5 minutes. When vital signs are scheduled at the same time as blood draws, the blood draws 
will be obtained at the scheduled timepoint and the vital signs will be obtained as close as 
possible to the scheduled blood draw, but prior to the blood draw. 
7.12 
HOW DO YOU FEEL? INQUIRY 
Subjects will be asked a non-leading HDYF? question such as “Have there been any changes in 
your health status since Screening/since you were last asked?” at the timepoints specified in 
Table 7-1. Subjects will also be encouraged to voluntarily report AEs occurring at any other time 
during the study. See Section 8.3 and Section 8.4 for reporting requirements for AEs and SAEs, 
respectively.

A routine physical examination will consist of an assessment of general appearance; skin; 
thorax/lungs; abdomen; lymph nodes; head, ears, eyes, nose, throat, and neck (including 
thyroid); and cardiovascular, musculoskeletal, and neurological systems. An abbreviated 
physical examination will consist of an assessment of general appearance, skin, thorax/lungs,

8 ADVERSE EXPERIENCES 
8.1 SAFETY PARAMETERS AND DEFINITIONS 
Safety assessments will consist of monitoring and recording AEs, including SAEs and AEs of 
special interest (AESIs), performing protocol-specified safety laboratory assessments, measuring 
protocol-specified vital signs, and conducting other protocol-specified tests that are deemed 
critical to the safety evaluation of the study. The Sponsor or its designee is responsible for 
reporting relevant SAEs to the competent authority, other applicable regulatory authorities, and 
participating Investigators, in accordance with the International Conference on 
Harmonisation/International Council for Harmonisation (ICH) guidelines, Food and Drug 
Administration (FDA) regulations, European Clinical Trials Directive (Directive 2001/20/EC), 
and/or local regulatory requirements. 
 
Certain types of events require immediate reporting to the Sponsor, as outlined in Section 8.4. 
8.1.1 ADVERSE EVENTS 
According to the ICH Guideline for Good Clinical Practice (GCP), an AE is any untoward 
medical occurrence in a clinical investigation subject administered a pharmaceutical product, 
regardless of causal attribution. An AE can therefore be any of the following: 

Clinical Protocol 
Covance Study 8397015 
CONFIDENTIAL 
Protocol GP41049 
 
 
Final:  5 November 2018 
Page 34 of 62 
CPET Protocol Template, Version 11.0:  30 April 2018 
• Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal product, whether 
or not considered related to the medicinal product 
• Any new disease or exacerbation of an existing disease (a worsening in the character, 
frequency, or severity of a known condition) 
• Recurrence of an intermittent medical condition (e.g., headache) not present at baseline 
• Any deterioration in a laboratory value or other clinical test (e.g., ECG, X-ray) that is 
associated with symptoms or leads to a change in study treatment or concomitant 
treatment or discontinuation from study drug 
• Adverse events that are related to a protocol-mandated intervention, including those that 
occur prior to assignment of study treatment (e.g., screening invasive procedures such as 
biopsies) 
8.1.2 SERIOUS ADVERSE EVENTS (IMMEDIATELY REPORTABLE TO THE 
SPONSOR) 
An SAE is any AE that meets any of the following criteria: 
• Is fatal (i.e., the AE actually causes or leads to death) 
• Is life-threatening (i.e., the AE, in the view of the Investigator, places the subject at 
immediate risk of death); this does not include any AE that had it occurred in a more 
severe form or was allowed to continue might have caused death 
• Requires or prolongs inpatient hospitalization 
• Results in persistent or significant disability/incapacity (i.e., the AE results in substantial 
disruption of the subject’s ability to conduct normal life functions) 
• Is a congenital anomaly/birth defect in a neonate/infant born to a mother exposed to study 
drug 
• Is a significant medical event in the Investigator’s judgment (e.g., may jeopardize the 
subject or may require medical/surgical intervention to prevent one of the outcomes listed 
above) 
 
All AEs that do not meet any of the criteria for serious should be regarded as non-serious AEs. 
 
The terms “severe” and “serious” are not synonymous. Severity refers to the intensity of an AE 
(e.g., rated as mild, moderate, or severe, according to National Cancer Institute Common 
Terminology Criteria for Adverse Events [NCI CTCAE]); the event itself may be of relatively 
minor medical significance (such as severe headache) without any further findings. An event 
should be considered “serious” only if it meets the regulatory criteria outlined in the 
above-mentioned paragraph outlining seriousness criteria.

Page 35 of 62 
CPET Protocol Template, Version 11.0:  30 April 2018 
 
Seriousness (not severity) serves as the guide for defining regulatory reporting obligations. 
 
Severity, seriousness, and causality need to be independently assessed for each AE recorded on 
the eCRF. 
 
Serious AEs are required to be reported by the Investigator to the Sponsor via the Covance 
Project Manager immediately (i.e., no more than 24 hours after learning of the event; see 
Section 8.4.2 for reporting instructions). 
8.1.3 ADVERSE EVENTS OF SPECIAL INTEREST (IMMEDIATELY REPORTABLE 
TO THE SPONSOR) 
Adverse events of special interest are required to be reported by the Investigator to the Sponsor 
via the Covance Project Manager immediately (i.e., no more than 24 hours after learning of the 
event; see Section 8.4.2 for reporting instructions). Adverse events of special interest for this 
study are as follows: 
• Cases of potential drug-induced liver injury that include an elevated alanine 
aminotransferase (ALT) or aspartate aminotransferase (AST) in combination with either 
an elevated bilirubin or clinical jaundice, as defined by Hy’s Law (see Section 8.3.1.6); 
• Suspected transmission of an infectious agent by the study drug as defined below: 
o Any organism, virus, or infectious particle (e.g., prion protein transmitting 
transmissible spongiform encephalopathy), pathogenic or non-pathogenic, is 
considered an infectious agent. A transmission of an infectious agent may be 
suspected from clinical symptoms or laboratory findings that indicate an infection 
in a subject exposed to a medicinal product. The term applies only when a 
contamination of the study drug is suspected. 
• All grades syncope events 
• Grade ≥2 congestive cardiac failure 
• Grade ≥2 QT prolongation 
• Grade ≥3 cognitive disturbances (including confusion, mental status changes, 
hallucinations, or memory loss) 
8.2 METHODS AND TIMING FOR CAPTURING AND ASSESSING SAFETY 
PARAMETERS 
The Investigator is responsible for ensuring that all AEs (as defined in Section 8.1) are recorded 
on the AE eCRF and reported to the Sponsor via the Covance Project Manager in accordance 
with protocol instructions (see Section 8.4.2).

Final:  5 November 2018 
Page 36 of 62 
CPET Protocol Template, Version 11.0:  30 April 2018 
 
For each AE recorded on the AE eCRF, the Investigator will make an assessment of seriousness 
(see Section 8.1.2 for seriousness criteria), severity, and causality (see Sections 8.2.3 and 8.2.4). 
8.2.1 ADVERSE EVENT REPORTING PERIOD 
Investigators will seek information on AEs at each subject contact. All AEs, whether reported by 
the subject or noted by study personnel, will be recorded in the subject’s medical record and on 
the AE eCRF. 
 
After informed consent has been obtained but prior to initiation of study drug administration, 
only SAEs caused by a protocol-mandated intervention (e.g., discontinuation of medications) 
will be reported (see Section 8.4.2 for instructions for reporting SAEs). After initiation of study 
drug administration, all AEs will be reported until 28 days after the final dose. 
 
Instructions for reporting AEs that occur after the AE reporting period are provided in 
Section 8.5. 
 
The Investigator is not required to actively monitor subjects after the study has ended or for AEs 
after the end of the AE reporting period (defined as 28 days after the final dose of study drug). 
However, the Sponsor should be notified if the Investigator becomes aware of any death, other 
SAEs, or AESIs occurring after the end of the AE reporting period that are believed to be related 
to prior study drug treatment. The Sponsor should also be notified if the Investigator becomes 
aware of the development of cancer or a congenital anomaly/birth defect in a subsequently 
conceived offspring of a female subject exposed to study drug (or the female partner of a male 
subject exposed to study drug). 
8.2.2 ELICITING ADVERSE EVENT INFORMATION 
A consistent methodology of non-directive questioning should be adopted for eliciting AE 
information at all subject evaluation timepoints. Examples of non-directive questions include the 
following: 
• “How have you felt since your last clinic visit?” 
• “Have you had any new or changed health problems since you were last here?”

8.2.3 ASSESSMENT OF SEVERITY OF ADVERSE EVENTS 
The AE severity grading scale for the NCI CTCAE (version 5.0) will be used for assessing AE 
severity. Table 8-1 will be used for assessing AE severity for AEs that are not specifically listed 
in the NCI CTCAE.

a Instrumental activities of daily living refer to preparing meals, shopping for groceries or clothes, using the 
telephone, managing money, etc. 
b Examples of self-care activities of daily living include bathing, dressing and undressing, feeding oneself, using 
the toilet, and taking medications, as performed by subjects who are not bedridden. 
c If an event is assessed as a “significant medical event,” it must be reported as an SAE (see Section 8.4.2 for 
reporting instructions), per the definition of SAE in Section 8.1.2. 
d Grade 4 and 5 events must be reported as SAEs (see Section 8.4 for reporting instructions), per the definition of 
SAE in Section 8.1.2. 
8.2.4 ASSESSMENT OF CAUSALITY OF ADVERSE EVENTS 
Investigators should use their knowledge of the subject, the circumstances surrounding the event, 
and an evaluation of any potential alternative causes to determine whether an AE is considered to 
be related to the study drug, indicating “yes” or “no” accordingly. The following guidance 
should be taken into consideration (see also Table 8-2): 
• Temporal relationship of event onset to the initiation of study drug 
• Course of the event, with special consideration of the effects of dose reduction, 
discontinuation of study drug, or reintroduction of study drug (as applicable) 
• Known association of the event with the study drug or with similar treatments 
• Known association of the event with the disease under study

Page 38 of 62 
CPET Protocol Template, Version 11.0:  30 April 2018 
• Presence of risk factors in the subject or use of concomitant medications known to 
increase the occurrence of the event 
• Presence of non-treatment-related factors that are known to be associated with the 
occurrence of the event 
Table 8-2 
Causal Attribution Guidance 
Is the adverse event suspected to be caused by the study drug based on facts, evidence, science-based rationales, and 
clinical judgment? 
YES 
There is a plausible temporal relationship between the onset of the adverse event and administration of the 
study drug, and the adverse event cannot be readily explained by the subject’s clinical state, intercurrent 
illness, or concomitant therapies; and/or the adverse event follows a known pattern of response to the 
study drug; and/or the adverse event abates or resolves upon discontinuation of the study drug or dose 
reduction and, if applicable, reappears upon re-challenge. 
Investigators should apply facts, evidence, or rationales based on scientific principles and clinical 
judgment to support a causal/contributory association with a study drug. 
NO 
Adverse events will be considered related, unless they fulfill the criteria as specified below. 
Evidence exists that the adverse event has an etiology other than the study drug (e.g., pre-existing medical 
condition, underlying disease, intercurrent illness, or concomitant medication); and/or the adverse event 
has no plausible temporal relationship to administration of the study drug (e.g., cancer diagnosed 2 days 
after first dose of study drug). 
Note:  The Investigator’s assessment of causality for individual adverse event reports is part of the study 
documentation process. Regardless of the “Yes” or “No” causality assessment for individual adverse event 
reports, the Sponsor will promptly evaluate all reported serious adverse events against cumulative product 
experience to identify and expeditiously communicate possible new safety findings to Investigators and 
applicable regulatory authorities. Attribution of serious adverse events will be reviewed on an ongoing 
basis, and may be changed as additional clinical data emerges (e.g., reversibility of adverse event, 
new clinical findings in subject with adverse event, effects of re-treatment, and adverse events in 
other subjects). 
8.3 PROCEDURES FOR RECORDING ADVERSE EVENTS 
8.3.1 RECORDING ADVERSE EVENTS ON THE CASE REPORT FORM 
Investigators should use correct medical terminology/concepts when recording AEs on the AE 
eCRF. Colloquialisms and abbreviations should be avoided. 
 
All AEs should be recorded on the AE eCRF page. If the AE qualifies as an SAE or non-serious 
AESI, the Investigator should record all case details that can be gathered immediately (i.e., 
within 24 hours after learning of the event) on a paper Clinical Trial SAE/AESI Reporting Form. 
The completed paper Clinical Trial SAE/AESI Reporting Form and safety fax coversheet should 
be emailed to Roche Safety Risk Management via the Covance Project Manager within 24 hours 
of learning of the event (see Section 8.4.2). The AE and SAE eCRF should also be completed 
within this timeframe. It is important that the information on the SAE Reporting Form and AE 
and SAE eCRF is consistent and identical.

Protocol GP41049 
 
 
Final:  5 November 2018 
Page 39 of 62 
CPET Protocol Template, Version 11.0:  30 April 2018 
 
Only 1 AE term should be recorded in the event field on the AE eCRF. 
8.3.1.1 DIAGNOSIS VERSUS SIGNS AND SYMPTOMS 
If known, a diagnosis should be recorded on the AE eCRF rather than individual signs and 
symptoms (e.g., record only liver failure or hepatitis rather than jaundice, asterixis, and elevated 
transaminases). However, if a constellation of signs and/or symptoms cannot be medically 
characterized as a single diagnosis or syndrome at the time of reporting, each individual event 
should be recorded on the AE eCRF. If a diagnosis is subsequently established, all previously 
reported AEs based on signs and symptoms should be nullified and replaced by 1 AE report 
based on the single diagnosis, with a starting date that corresponds to the starting date of the first 
symptom of the eventual diagnosis. 
8.3.1.2 ADVERSE EVENTS THAT ARE SECONDARY TO OTHER EVENTS 
In general, AEs that are secondary to other events (e.g., cascade events or clinical sequelae) 
should be identified by their primary cause, with the exception of severe or serious secondary 
events. A medically significant secondary AE that is separated in time from the initiating event 
should be recorded as an independent event on the AE eCRF. For example: 
• If vomiting results in mild dehydration with no additional treatment in a healthy adult, 
only vomiting should be reported on the eCRF. 
• If vomiting results in severe dehydration, both events should be reported separately on 
the eCRF. 
• If a severe GI hemorrhage leads to renal failure, both events should be reported 
separately on the eCRF. 
• If dizziness leads to a fall and subsequent fracture, all 3 events should be reported 
separately on the eCRF. 
• If neutropenia is accompanied by an infection, both events should be reported separately 
on the eCRF. 
 
All AEs should be recorded separately on the AE eCRF if it is unclear as to whether the events 
are associated. 
8.3.1.3 PERSISTENT OR RECURRENT ADVERSE EVENTS 
A persistent AE is one that extends continuously, without resolution between subject evaluation 
timepoints. Such events should only be recorded once in the AE eCRF. The initial severity 
(intensity or grade) of the event will be recorded at the time the event is first reported. If a

Final:  5 November 2018 
Page 40 of 62 
CPET Protocol Template, Version 11.0:  30 April 2018 
persistent AE becomes more severe, the most extreme severity should also be recorded on the 
AE eCRF. If the event becomes serious, it should be reported to the Sponsor immediately (i.e., 
no more than 24 hours after learning that the event became serious; see Section 8.4.2 for 
reporting instructions). The AE eCRF should be updated by changing the event from 
“non-serious” to “serious,” providing the date that the event became serious, and by completing 
all data fields related to SAEs. 
 
A recurrent AE is one that resolves between subject evaluation timepoints and subsequently 
recurs. Each recurrence of an AE should be recorded as a separate event on the AE eCRF. 
8.3.1.4 ABNORMAL LABORATORY VALUES 
Not every laboratory abnormality qualifies as an AE. A laboratory test result should be reported 
as an AE if it meets any of the following criteria: 
• Is accompanied by clinical symptoms 
• Results in a change in study treatment (e.g., dosage modification, treatment interruption, 
or treatment discontinuation) 
• Results in a medical intervention (e.g., potassium supplementation for hypokalemia) or a 
change in concomitant therapy 
• Is clinically significant in the Investigator’s judgment 
 
It is the Investigator’s responsibility to review all laboratory findings. Medical and scientific 
judgment should be exercised in deciding whether an isolated laboratory abnormality should be 
classified as an AE. 
 
If a clinically significant laboratory abnormality is a sign of a disease or syndrome (e.g., alkaline 
phosphatase and bilirubin 5 times the upper limit of normal [ULN] associated with cholestasis), 
only the diagnosis (i.e., cholestasis) should be recorded on the AE eCRF. 
 
If a clinically significant laboratory abnormality is not a sign of a disease or syndrome, the 
abnormality itself should be recorded on the AE eCRF, along with a descriptor indicating 
whether the test result is above or below the normal range (e.g., “elevated potassium,” as 
opposed to “abnormal potassium”). If the laboratory abnormality can be characterized by a 
precise clinical term per standard definitions, the clinical term should be recorded as the AE. For 
example, an elevated serum potassium level of 7.0 mEq/L should be recorded as “hyperkalemia.”

Observations of the same clinically significant laboratory abnormality from visit to visit should 
only be recorded once on the AE eCRF (see Section 8.3.1.3 for details on recording persistent 
AEs). 
8.3.1.5 ABNORMAL VITAL SIGN VALUES 
Not every vital sign abnormality qualifies as an AE. A vital sign result should be reported as an 
AE if it meets any of the following criteria: 
• Is accompanied by clinical symptoms 
• Results in a change in study treatment (e.g., dosage modification, treatment interruption, 
or treatment discontinuation) 
• Results in a medical intervention or a change in concomitant therapy 
• Is clinically significant in the Investigator’s judgment 
 
It is the Investigator’s responsibility to review all vital sign findings. Medical and scientific 
judgment should be exercised in deciding whether an isolated vital sign abnormality should be 
classified as an AE. 
 
If a clinically significant vital sign abnormality is a sign of a disease or syndrome (e.g., high 
blood pressure), only the diagnosis (i.e., hypertension) should be recorded on the AE eCRF. 
 
Observations of the same clinically significant vital sign abnormality from visit to visit should 
only be recorded once on the AE eCRF (see Section 8.3.1.3 for details on recording persistent 
AEs). 
8.3.1.6 ABNORMAL LIVER FUNCTION TESTS 
The finding of an elevated ALT or AST (>3 × ULN) in combination with either an elevated total 
bilirubin (>2 × ULN) or clinical jaundice in the absence of cholestasis or other causes of 
hyperbilirubinemia is considered to be an indicator of severe liver injury (as defined by Hy’s 
Law). Therefore, Investigators must report the occurrence of either of the following as an AE: 
• Treatment-emergent ALT or AST >3 × ULN in combination with total bilirubin >2 × 
ULN 
• Treatment-emergent ALT or AST >3 × ULN in combination with clinical jaundice 
 
The most appropriate diagnosis or (if a diagnosis cannot be established) the abnormal laboratory 
values should be recorded on the AE eCRF (see Section 8.3.1) and reported to the Sponsor 
immediately (i.e., no more than 24 hours after learning of the event), either as an SAE or an 
AESI (see Section 8.4.2).

8.3.1.7 DEATHS 
All deaths that occur during the protocol-specified AE reporting period (see Section 8.2.1), 
regardless of relationship to study drug, will be recorded on the AE eCRF as well as on the paper 
Clinical Trial SAE Reporting Form and immediately reported to the Sponsor via the Covance 
Project Manager (see Section 8.4.2 for reporting instructions). 
 
Death should be considered an outcome and not a distinct event. The event or condition that 
caused or contributed to the fatal outcome should be recorded as the single medical concept on 
the AE eCRF. Generally, only 1 such event should be reported. If the cause of death is unknown 
and cannot be ascertained at the time of reporting, “unexplained death” should be recorded on 
the AE eCRF. If the cause of death later becomes available (e.g., after autopsy), “unexplained 
death” should be replaced by the established cause of death. The term “sudden death” should not 
be used unless combined with the presumed cause of death (e.g., “sudden cardiac death”). 
 
Deaths that occur after the AE reporting period should be reported as described in Section 8.5. 
8.3.1.8 PRE-EXISTING MEDICAL CONDITIONS 
A pre-existing medical condition is one that is present at the Screening visit for this study. Such 
conditions should be recorded on the General Medical History and Baseline Conditions eCRF 
page. 
 
A pre-existing medical condition should be recorded as an AE only if the frequency, severity, or 
character of the condition worsens during the study. When recording such events on an AE 
eCRF, it is important to convey the concept that the pre-existing condition has changed by 
including applicable descriptors (e.g., “accelerated worsening of headaches”). 
8.3.1.9 
HOSPITALIZATION OR PROLONGED HOSPITALIZATION 
Any AE that results in hospitalization (i.e., inpatient admission to a hospital) or prolonged 
hospitalization should be documented and reported as an SAE (per the definition of SAE in 
Section 8.1.2) except as outlined below. 
 
An event that leads to hospitalization under the following circumstances should not be reported 
as an AE or SAE: 
• Hospitalization for respite care 
• Hospitalization for a pre-existing condition, provided that all of the following criteria are 
met:

o The hospitalization was planned prior to the study or was scheduled during the 
study when elective surgery became necessary because of the expected normal 
progression of the disease 
o The subject has not experienced an AE 
 
An event that leads to hospitalization under the following circumstances is not considered to be 
an SAE but should be reported as an AE instead: 
• Hospitalization that was necessary because of the subject’s requirement for outpatient 
care outside of normal outpatient clinic operation hours 
8.4 IMMEDIATE REPORTING REQUIREMENTS FROM INVESTIGATOR TO 
SPONSOR 
Certain events require immediate reporting to allow the Sponsor to take appropriate measures to 
address potential new risks in a clinical trial. The Investigator must report such events to the 
Sponsor immediately via the Covance Project Manager; under no circumstances should reporting 
take place more than 24 hours after the Investigator learns of the event. The following is a list of 
events that the Investigator must report to the Sponsor within 24 hours (see Section 8.4.2) after 
learning of the event, regardless of relationship to study drug: 
• SAEs (see Section 8.4.2 for further details) 
• AESIs (see Section 8.1.3 for further details) 
• Pregnancies (see Section 8.4.2.3 for further details) 
• Accidental overdoses or medication errors (see Section 8.4.3 for details on reporting 
requirements) 
 
The Investigator must report new significant follow-up information for these events to the 
Sponsor immediately via the Covance Project Manager (i.e., no more than 24 hours after 
becoming aware of the information). New significant information includes the following: 
• New signs or symptoms or a change in the diagnosis 
• Significant new diagnostic test results 
• Change in causality based on new information 
• Change in the event’s outcome, including recovery 
• Additional narrative information on the clinical course of the event 
 
Investigators must also comply with local requirements for reporting SAEs to the local health 
authority and Institutional Review Board (IRB)/Ethics Committee (EC).

Relevant follow-up information should be submitted to Roche Safety Risk Management via the 
Covance Project Manager on an updated paper Clinical Trial SAE/AESI Reporting Form as soon 
as it becomes available and/or upon request. Any updates to the paper Clinical Trial SAE/AESI 
Reporting Form must also be updated in electronic data capture (EDC) on the AE eCRF. 
8.4.2.3 REPORTING REQUIREMENTS FOR PREGNANCIES 
8.4.2.3.1 
PREGNANCIES IN FEMALE SUBJECTS 
Female subjects of childbearing potential will be instructed to immediately inform the 
Investigator if they become pregnant during the study or within 28 days after the final dose of 
study drug. A paper Clinical Trial Pregnancy Reporting Form should be completed by the 
Investigator immediately (i.e., no more than 24 hours after learning of the pregnancy) and 
emailed to Roche Safety Risk Management via the Covance Project Manager (see Section 8.4.2 
for reporting instructions). Pregnancy should not be recorded on the AE eCRF. The Investigator 
should discontinue study drug and counsel the subject, discussing the risks of the pregnancy and 
the possible effects on the fetus. Monitoring of the subject should continue until conclusion of 
the pregnancy. Any SAEs associated with the pregnancy (e.g., an event in the fetus, an event in 
the mother during or after the pregnancy, or a congenital anomaly/birth defect in the child) 
should be reported on the AE eCRF. In addition, the Investigator will submit a paper Clinical 
Trial Pregnancy Reporting Form when updated information on the course and outcome of the 
pregnancy becomes available. 
8.4.2.3.2 
PREGNANCIES IN FEMALE PARTNERS OF MALE SUBJECTS 
Male subjects will be instructed through the ICF to immediately inform the Investigator if their 
partner becomes pregnant during the study or within 28 days after the final dose of study drug. A 
paper Clinical Trial Pregnancy Reporting Form should be completed by the Investigator 
immediately (i.e., no more than 24 hours after learning of the pregnancy) and emailed to Roche 
Safety Risk Management via the Covance Project Manager (see Section 8.4.2 for reporting 
instructions). Attempts should be made to collect and report details of the course and outcome of 
any pregnancy in the partner of a male subject exposed to study drug. When permitted by the 
site, the pregnant partner would need to sign an Authorization for Use and Disclosure of 
Pregnancy Health Information to allow for follow-up on her pregnancy. If the authorization has 
been signed, the Investigator should submit a Clinical Trial Pregnancy Reporting Form when 
updated information on the course and outcome of the pregnancy becomes available. An 
Investigator who is contacted by the male subject or his pregnant partner may provide 
information on the risks of the pregnancy and the possible effects on the fetus, to support an 
informed decision in cooperation with the treating physician and/or obstetrician.

8.4.2.3.3 
CONGENITAL ANOMALIES/BIRTH DEFECTS AND ABORTIONS 
Any congenital anomaly/birth defect in a child born to a female subject exposed to the study 
drug or the female partner of a male subject exposed to the study drug should be classified as an 
SAE, recorded on the AE eCRF, and reported to the Sponsor immediately via the Covance 
Project Manager (i.e., no more than 24 hours after learning of the event; see Section 8.4.2). Any 
abortion should be reported in the same fashion (as the Sponsor considers abortions to be 
medically significant events). 
8.4.3 REPORTING REQUIREMENTS FOR CASES OF ACCIDENTAL OVERDOSE 
OR MEDICATION ERROR 
Accidental overdose and medication error (hereafter collectively referred to as “special 
situations”), are defined as follows: 
• Accidental overdose:  accidental administration of a drug in a quantity that is higher than 
the assigned dose 
• Medication error:  accidental deviation in the administration of a drug 
 
In some cases, a medication error may be intercepted prior to administration of the drug. 
 
Special situations are not in themselves AEs, but may result in AEs. Each AE associated with a 
special situation should be recorded separately on the AE eCRF. If the associated AE fulfills 
seriousness criteria, the event should be reported to the Sponsor immediately (i.e., no more than 
24 hours after learning of the event; see Section 8.4.2). For entrectinib, AEs associated with 
special situations should be recorded as described below for each situation: 
• Accidental overdose:  Enter the AE term. Check the “Accidental overdose” and 
“Medication error” boxes. 
• Medication error that does not qualify as an overdose:  Enter the AE term. Check the 
“Medication error” box. 
• Medication error that qualifies as an overdose:  Enter the AE term. Check the “Accidental 
overdose” and “Medication error” boxes. 
 
In addition, all special situations associated with entrectinib, regardless of whether they result in 
an AE, should be recorded on the AE eCRF and reported to the Sponsor immediately (i.e., no 
more than 24 hours after learning of the event). Special situations should be recorded as 
described below: 
• Accidental overdose:  Enter the drug name and “accidental overdose” as the event term. 
Check the “Accidental overdose” and “Medication error” boxes.

• Medication error that does not qualify as an overdose:  Enter the name of the drug 
administered and a description of the error (e.g., wrong dose administered, wrong dosing 
schedule, incorrect route of administration, wrong drug, expired drug administered) as the 
event term. Check the “Medication error” box. 
• Medication error that qualifies as an overdose:  Enter the drug name and “accidental 
overdose” as the event term. Check the “Accidental overdose” and “Medication error” 
boxes. Enter a description of the error in the additional case details. 
• Intercepted medication error:  Enter the drug name and “intercepted medication error” as 
the event term. Check the “Medication error” box. Enter a description of the error in the 
additional case details. 
 
As an example, an accidental overdose that resulted in a headache would require the completion 
of 2 AE eCRF pages, one to report the accidental overdose and one to report the headache. The 
“Accidental overdose” and “Medication error” boxes would need to be checked on both eCRF 
pages. 
8.4.4 FOLLOW-UP OF SUBJECTS AFTER ADVERSE EVENTS 
8.4.4.1 INVESTIGATOR FOLLOW-UP 
The Investigator should follow each AE until the event has resolved to baseline grade or better, 
the event is assessed as stable by the Investigator, the subject is lost to follow-up, or the subject 
withdraws consent. Every effort should be made to follow all SAEs considered to be related to 
study drug or trial-related procedures until a final outcome can be reported. During the study 
period, resolution of AEs (with dates) should be documented on the AE eCRF and in the 
subject’s medical record to facilitate source data verification. 
 
All pregnancies reported during the study should be followed until pregnancy outcome. 
8.4.4.2 SPONSOR FOLLOW-UP 
For SAEs, AESIs, and pregnancies, the Sponsor or a designee may follow-up by telephone, fax, 
email, and/or a monitoring visit to obtain additional case details and outcome information (e.g., 
from hospital discharge summaries, consultant reports, autopsy reports) in order to perform an 
independent medical assessment of the reported case.

8.5 ADVERSE EVENTS THAT OCCUR AFTER THE ADVERSE EVENT REPORTING 
PERIOD 
At the Follow-up/ET visit, the Investigator should instruct each subject to report to the 
Investigator any subsequent AEs that the subject’s personal physician believes could be related 
to prior study drug treatment or study procedures. The Sponsor should be notified if the 
Investigator becomes aware of any SAE that occurs after the end of the AE reporting period 
(defined as 28 days after the final dose of study drug) if the event is believed to be related to 
prior study drug treatment. 
 
These events should be reported through the use of the AE eCRF. However, if the EDC system is 
not available, the Investigator should report these events directly to the Sponsor or its designee, 
by faxing or by scanning and emailing the paper Clinical Trial SAE/AESI Reporting Form using 
the below fax number or email address provided to Investigators.

8.5.1 EXPEDITED REPORTING TO HEALTH AUTHORITIES, INVESTIGATORS, 
INSTITUTIONAL REVIEW BOARDS, AND ETHICS COMMITTEES 
The Sponsor will promptly evaluate all SAEs and AESIs against cumulative product experience 
to identify and expeditiously communicate possible new safety findings to Investigators, IRBs, 
ECs, and applicable health authorities based on applicable legislation. 
 
To determine reporting requirements for single AE cases, the Sponsor will assess the 
expectedness of these events using the following reference document: 
 
• Entrectinib IB 
 
The Sponsor will compare the severity of each event and the cumulative event frequency 
reported for the study with the severity and frequency reported in the applicable reference 
document. 
 
Reporting requirements will also be based on the Investigator’s assessment of causality and 
seriousness, with allowance for upgrading by the Sponsor, as needed.

The IRB will be notified by the investigative site in writing (e.g., email) within the timeframe 
required per local IRB regulations for when a reportable AE is first recognized or reported. In 
addition, a copy of the written confirmation or summary of the AE, as submitted to the Sponsor, 
will also be submitted to the IRB within that same timeframe from when the AE is first 
recognized or reported. The IRB Serious and Unexpected AE Submission Form will be 
completed and submitted with the copy of the written confirmation or summary of the AE. 
9 STATISTICAL ANALYSES 
The Safety Population will consist of all subjects who received at least 1 dose of study drug and 
have at least 1 postdose safety assessment. 
 
The PK Population will consist of all subjects who received at least 1 dose of study drug and 
have at least 1 evaluable postdose PK sample. 
 
Baseline is defined as the last result prior to the first dose of study drug on Day 1 of Period 1. As 
necessary, baseline will be further defined in the Statistical Analysis Plan (SAP). 
9.1 SAFETY AND TOLERABILITY ANALYSIS 
Safety will be assessed by a review of AEs, vital signs, clinical laboratory assessments, and 
ECGs. Clinical laboratory assessments, vital signs (including oral temperature, respiratory rate, 
and supine blood pressure and pulse rate), and ECGs will be listed by subject number and 
scheduled time. Changes from baseline will be summarized, as appropriate. 
 
Verbatim descriptions of AEs will be coded according to current Medical Dictionary for 
Regulatory Activities version 21.1 (or higher) guidelines. Adverse events will be summarized. 
Enrollment and discontinuations from the study will be summarized overall. Demographics and 
baseline characteristics such as age, sex, and BMI will be summarized overall. 
9.2 PHARMACOKINETIC ANALYSIS 
The following PK parameters will be derived from the plasma concentrations of entrectinib and 
M5 using the model independent approach:5 
Cmax 
maximum observed concentration 
tmax 
time to maximum observed concentration 
AUC0-t 
area under the concentration-time curve from Hour 0 to the last 
measurable concentration, calculated using the linear trapezoidal 
rule for increasing concentrations and the logarithmic rule for 
decreasing concentrations

t1/2 = (ln2)/λz 
CL/F 
apparent systemic clearance, calculated as dose/AUC0-∞ 
(entrectinib only) 
Vz/F 
apparent volume of distribution during the terminal elimination 
phase, calculated as (CL/F)/λz (entrectinib only) 
 
Pharmacokinetic calculations will be performed, if appropriate, using commercial software such 
as Phoenix WinNonlin (Certara Inc., version 6.4 or higher). 
 
Other parameters may be added, as appropriate. Final PK parameters reported will be detailed in 
the SAP. 
 
Pharmacokinetic analysis will use actual times as recorded on the eCRF. Other data handling 
procedures will be detailed in the SAP. 
9.3 INTERIM ANALYSIS 
There will not be any interim analysis for this study. 
9.4 STATISTICAL ANALYSIS OF PHARMACOKINETIC DATA 
Descriptive statistics (mean, median, minimum, maximum, standard deviation, geometric mean, 
and geometric coefficient of variation [CV]) will be calculated for all PK parameters and PK 
concentration data. 
 
Plasma concentrations of entrectinib and its active metabolite M5, and derived plasma PK 
parameters, will be listed and summarized by treatment using descriptive statistics. Individual 
and mean concentration versus time profiles will be plotted.

The primary parameters for bioequivalence testing will be Cmax and AUC0-t of entrectinib. A 
linear mixed model will be applied to analyze the log-transformed primary PK parameters. The 
model assumes fixed effects for treatment, period, and sequence, and a random effect for subject 
within sequence. Estimates of geometric mean ratios on the original scale, together with the 
corresponding 90% CIs, will be derived for the comparisons between Test and Reference 
treatments. Bioequivalence will be concluded if the 90% CIs for the treatment ratios fall within 
the no-effect boundaries of 0.80 and 1.25. 
 
All calculations will be performed using SAS version 9.4 or greater. 
 
Specification of PK parameters for analysis; statistical level of significance to be used; criteria 
for study termination; procedures for accounting for missing, unused, or spurious data; 
procedures for reporting deviations from the original statistical plan; and selection of subjects to 
be included in the analyses population(s) will be presented in the CSR and/or SAP, as 
appropriate. 
9.5 STATISTICAL ANALYSES OF SAFETY DATA 
Descriptive statistics will be calculated for the safety parameters. No formal statistical analyses 
are planned. 
9.6 SAMPLE SIZE 
A total of 28 subjects will be enrolled to ensure that 26 subjects complete the study and have 
evaluable PK data from both treatment periods. 
 
In a previous study (Study RXDX-101-15), the within-subject CVs for entrectinib AUC0-∞ and 
Cmax following administration of a single dose of entrectinib were estimated to be 20% and 16%, 
respectively. Assuming a true ratio of 1.05 between the geometric means of Test and Reference 
treatments, and a within-subject CV of 21%, 26 evaluable subjects are needed to ensure there is 
at least 90% probability that the 90% confidence limits for the treatment ratios fall within the 
no-effect boundaries of 0.80 and 1.25 for each of the 2 primary PK parameters (AUC0-∞ and 
Cmax). 
9.7 QUALITY CONTROL AND QUALITY ASSURANCE 
Quality control and quality assurance will be performed according to Covance Standard 
Operating Procedures (SOPs) or per client request and as applicable according to the contract 
between Covance and the Sponsor.

CHANGE IN PROTOCOL 
There will be no alterations in the protocol without agreement between the Sponsor and the 
Investigator. 
 
There will be no alterations in the protocol affecting subject safety without the express written 
approval of the Sponsor, Investigator, and the IRB (see Form FDA 1572). 
10.2 
INVESTIGATOR MEETING; SITE INITIATION 
Prior to the start of the clinical study, the representative(s) of the Sponsor will meet with the 
Investigator(s) and appropriate clinical staff to familiarize the Investigator and clinical staff with 
the materials necessary for conducting the clinical study. 
10.3 
DISCLOSURE 
All information provided regarding the study, as well as all information collected and 
documented during the course of the study, will be regarded as confidential. The Investigator 
agrees not to disclose such information in any way without prior written permission from the 
Sponsor. 
 
Any publication of the results, either in part or in total (e.g., articles in journals or newspapers, 
oral presentations, abstracts) by the Investigator(s) or their representative(s), shall require prior 
notification and review, within a reasonable timeframe, by the Sponsor, and cannot be made in 
violation of the Sponsor’s confidentiality restrictions or to the detriment of the Sponsor’s 
intellectual property rights. 
10.4 
MONITORING (CLINICAL RESEARCH ASSOCIATE) 
The Sponsor will designate a Sponsor’s Study Monitor who will be responsible for monitoring 
this clinical trial. The Sponsor’s Study Monitor will monitor the study conduct, proper eCRF and 
source documentation completion and retention, and accurate study drug accountability. To this 
end, the Sponsor’s Study Monitor will visit the study site at suitable intervals and be in frequent 
contact through verbal and written communication. It is essential that the Sponsor’s Study 
Monitor have access to all documents, including study data, subject medical records, and eCRFs, 
at any time these are requested. In turn, the Sponsor’s Study Monitor will adhere to all 
requirements for subject confidentiality as outlined in the ICF. The Investigator and

available during a portion of the monitoring visit to answer questions, and to provide any missing 
information. 
10.5 
INSTITUTIONAL REVIEW BOARD 
In accordance with 21 CFR 56, the protocol, advertisement, and ICF will be reviewed and 
approved by the IRB. The Sponsor will supply relevant material for the Investigator to submit to 
the IRB for the protocol’s review and approval. Verification of the IRB unconditional approval 
of the protocol and the written ICF statement will be transmitted to the Investigator. 
 
The IRB will be informed by the Investigator of subsequent protocol amendments and of serious 
and unexpected AEs. Approval for protocol amendments will be transmitted in writing to the 
Investigator. If requested, the Investigator will permit audits by the IRB and regulatory 
inspections by providing direct access to source data and documents. 
 
The Investigator will provide the IRB with progress reports at appropriate intervals (not to 
exceed 1 year) and a Study Progress Report following the completion, termination, or 
discontinuation of the Investigator’s participation in the study. 
10.6

The completed eCRFs will be transferred to the Sponsor or designee. Copies of each eCRF will 
be retained by the Investigator. All source documents, records, and reports will be retained by the 
study site in accordance with 21 CFR 312.62(c). 
 
All primary data, or copies thereof (e.g., laboratory records, eCRFs, data sheets, correspondence, 
photographs, and computer records), which are a result of the original observations and activities 
of the study and are necessary for the reconstruction and evaluation of any study report, will be 
retained in the study site archives. 
10.7.1 ELECTRONIC CASE REPORT FORMS 
Electronic Case Report Forms are to be completed using the Medidata RAVE EDC system. The 
site will receive training and have access to a manual for appropriate eCRF completion. 
Electronic Case Report Forms will be submitted electronically to Covance and should be handled 
in accordance with instructions from Genentech/Covance. All eCRFs should be completed by 
designated, trained examining personnel as appropriate. 
 
The results from Screening and data collected during the study will be recorded in the subject’s 
eCRF. To maintain confidentiality, the subjects will be identified only by numbers. The 
Investigator will ensure the accuracy, completeness, legibility, and timeliness of the data 
reported in the eCRF by providing an electronic signature. The completed eCRFs will be 
transferred to the Sponsor or designee. 
 
In addition, at the end of the study, the Investigator will receive subject data for the site in a 
readable format (e.g., a compact disc) that must be kept with the study records. 
10.7.2 SOURCE DATA DOCUMENTATION 
Study Monitors will perform ongoing source data verification and review to confirm that critical 
protocol data (i.e., source data) entered into the eCRFs by authorized site personnel are accurate, 
complete, and verifiable from source documents. 
 
Source documents (paper or electronic) are those in which subject data are recorded and 
documented for the first time. They include, but are not limited to, hospital records, clinical and 
office charts, laboratory notes, memoranda, subject diaries or evaluation checklists, pharmacy 
dispensing records, recorded data from automated instruments, copies of transcriptions that are 
certified after verification as being accurate and complete, microfiche, photographic negatives, 
microfilm or magnetic media, X-rays, subject files, and records kept at the pharmacy, 
laboratories, and medico-technical departments involved in a clinical trial. Source documents

that are required to verify the validity and completeness of data entered into the eCRFs must 
never be obliterated or destroyed. To facilitate source data verification and review, the 
Investigator and institution(s) must provide the Sponsor direct access to applicable source 
documents and reports for trial-related monitoring, Sponsor audits, and IRB/EC review. The 
study site must also allow inspection by applicable health authorities. 
10.7.3 USE OF COMPUTERIZED SYSTEMS 
When clinical observations are entered directly into a study site’s computerized medical record 
system (i.e., in lieu of original hardcopy records), the electronic record can serve as the source 
document if the system has been validated in accordance with FDA requirements pertaining to 
computerized systems used in clinical research. An acceptable computerized data collection 
system (for clinical research purposes) would be one that (1) allows data entry only by 
authorized individuals; (2) prevents the deletion or alteration of previously entered data and 
provides an audit trail for such data changes (e.g., modification of file); (3) protects the database 
from tampering; and (4) ensures data preservation. 
 
In collaboration with the Study Monitor, Genentech’s or Covance’s Quality Assurance group 
may assist in assessing whether electronic records generated from computerized medical record 
systems used at study sites can serve as source documents for the purposes of this protocol. If a 
site’s computerized medical record system is not adequately validated for the purposes of clinical 
research (as opposed to general clinical practice), applicable hardcopy source documents must be 
maintained to ensure that critical protocol data entered into the eCRFs can be verified. 
10.7.4 STUDY MEDICATION ACCOUNTABILITY 
The recipient of study medication will acknowledge receipt by returning the appropriate 
documentation form indicating shipment content and condition. Damaged supplies will be 
replaced. Accurate records of all study drug received at, dispensed from, returned to, and 
disposed of by the study site should be recorded by using the Drug Inventory Log. 
 
Study drug will either be disposed of at the study site according to the study site’s institutional 
SOP or returned to Genentech with the appropriate documentation, as determined by the 
Sponsor. If the study site is able to destroy study drug, the method of destruction must be 
documented. Genentech must evaluate and approve the study site’s drug destruction SOP prior to 
the initiation of drug destruction by the study site.

10.7.5 DISCLOSURE OF DATA 
Subject medical information obtained by this study is confidential and may only be disclosed to 
third parties as permitted by the ICF (or separate authorization to use and disclose personal 
health information) signed by the subject or unless permitted or required by law. Medical 
information may be given to a subject’s personal physician or other appropriate medical 
personnel responsible for the subject’s welfare for treatment purposes. 
 
Given the complexity and exploratory nature of the analyses, data derived from exploratory 
biomarker specimens will generally not be provided to study Investigators or subjects unless 
required by law. The aggregate results of any conducted research will be available in accordance 
with the effective Sponsor policy on study data publication. 
 
Data generated by this study must be available for inspection upon request by representatives of 
the US FDA and other regulatory agencies, national and local health authorities, Genentech 
monitors/representatives and collaborators, and the IRB/EC for the study site, if appropriate. 
 
Study data may be submitted to government or other health research databases or shared with 
researchers, government agencies, companies, or other groups that are not participating in this 
study. These data may be combined with or linked to other data and used for research purposes; 
to advance science and public health; or for analysis, development, and commercialization of 
products to treat and diagnose disease. In addition, redacted CSRs and other summary reports 
will be provided upon request. 
10.7.6 RETENTION OF RECORDS 
The US FDA regulations (21 CFR §312.62[c]) and the ICH Guideline for GCP require that 
records and documents pertaining to the conduct of this study and the distribution of 
investigational drug, including eCRFs, ICFs, laboratory test results, and medication inventory 
records, must be retained by the Investigator for 2 years after the last marketing application 
approval in an ICH region or after at least 2 years have elapsed since formal discontinuation of 
clinical development of the study drug. All state and local laws for retention of records also 
apply. No records should be disposed of without the written approval of the Sponsor. Written 
notification should be provided to the Sponsor prior to transferring any records to another party 
or moving them to another location. For studies conducted outside the US under a US 
Investigational New Drug (IND), the Investigator must comply with the record retention 
requirements set forth in the US FDA IND regulations and the relevant national and local health 
authorities, whichever is longer.
