Conditions: Hepatic Insufficiency
Keywords: Hepatic Impairment
Sponsor: Hoffmann-La Roche
Start date: 2020-02-11; Completion date: 2021-09-27
Enrollment: 38 participants; Allocation: NON_RANDOMIZED; Intervention model: PARALLEL

Brief summary:
This is a non-randomized, open-label, one treatment, four group, parallel group study to investigate the effect of impaired hepatic function on the pharmacokinetics of entrectinib in participants with different levels of hepatic function. Participants with mild, moderate or severe hepatic impairment ('Mild', 'Moderate' and 'Severe' groups), and control participants with normal hepatic function ('Normal' group) will each receive a single 100 mg dose of entrectinib after consumption of a standardized meal.

Detailed description:
Participants with reduced hepatic function will be assigned to a functional category based on assessments at the Screening visit. Each individual will be categorized according to the Child Pugh system for classifying hepatic impairment and also according to the National Cancer Institute organ dysfunction working group (NCI-ODWG) system. Recruitment will be staggered to allow review of pharmacokinetic and safety data from at least three participants in each of the Mild and Moderate groups before participants are enrolled into the Severe group. Recruitment of the Severe group will only proceed if there is agreement between the Sponsor and the Investigator that data from this group are necessary to fulfill the objectives of the study and that dosing is not anticipated to present an unacceptable risk to those individuals. The control group of participants with normal hepatic function will be enrolled after the full complement of participants with hepatic dysfunction has been dosed.

Arms: arm 1: Participants with mild hepatic impairment will receive 1x100 milligram (mg) F06 (entrectinib) capsule administered orally with approximately 240 milliliter (mL) water within 30 minutes after consumption of a standardized meal. arm 2: Participants with moderate hepatic impairment will receive 1x100 mg F06 (entrectinib) capsule administered orally with approximately 240 mL water within 30 minutes after consumption of a standardized meal. arm 3: Participants with severe hepatic impairment will receive 1x100 mg F06 (entrectinib) capsule administered orally with approximately 240 mL water within 30 minutes after consumption of a standardized meal. arm 4: Participants with normal hepatic function will receive 1x100 mg F06 (entrectinib) capsule administered orally with approximately 240 mL water within 30 minutes after consumption of a standardized meal.
Interventions: intervention 1: entrectinib
Intervention descriptions: intervention 1: 1x100 milligram (mg) capsule given with approximately 240 milliliter (mL) of water within 30 minutes of consumption of a standardized meal

PROTOCOL AMENDMENT, VERSION 2:
RATIONALE
Protocol GP41174 has been amended to update safety data to align with most recent 
Entrectinib Investigator's Brochure (Version 9, Addendum 1).  Changes to the protocol, 
along with a rationale for each change, are summarized below:

Inclusion of the safety risks has been added to list of less common risks for 
entrectinib and the information has been put in tabular form (Section 1.1.4):
Less Common (occurs in 1%10% of patients)

Difficulty swallowing

Bone fracture

Fainting due to drop in blood pressure

Weakness of the heart muscle causing decreased pumping of blood, which may cause 
breathing difficulty, reduced kidney function, and fluid accumulation

Electrocardiogram (ECG) QT prolonged, which may mean heart is not working normally

The protocol has been updated to specify that women of child-bearing potential are 
required to remain abstinent or use a highly effective method of contraception 
throughout the study and for 5 weeks after last study treatment. Men with female 
partners of child-bearing potential must agree to remain abstinent or use barrier 
contraception throughout the study and for 3 months after the last study treatment. 
Men whose female partners are pregnant must also use barrier contraception 
throughout the study to avoid potential exposure of the fetus to the study drug
(Sections 1.2.2 and 4.4.2).

Information has been added to clarify that re-screening is not allowed (Section 3.1).

Information about future use of screening samples has been added (Section 4.5.5).
Additional minor changes have been made to improve clarity and consistency.  
Substantive new information appears in italics.  This amendment represents cumulative 
changes to the original protocol.

OVERALL DESIGN
Study Design
This is a non-randomized, open-label, one treatment, four group, parallel group study to 
investigate the effect of impaired hepatic function on the pharmacokinetics of entrectinib in 
volunteers with different levels of hepatic function. Volunteers with mild, moderate or severe 
hepatic impairment (‘Mild’, ‘Moderate’ and ‘Severe’ groups), and control volunteers with normal 
hepatic function (‘Normal’ group) will each receive a single 100 mg dose of entrectinib after 
consumption of a standardized meal.
Volunteers with reduced hepatic function will be assigned to a functional category based on 
assessments at the Screening visit. Each individual will be categorized according to the Child 
Pugh system for classifying hepatic impairment and also according to the National Cancer 
Institute organ dysfunction working group (NCI-ODWG) system. Sufficient volunteers will be 
enrolled to ensure that at least six individuals are recruited in each hepatic function group for 
both classification systems.
Recruitment will be staggered to allow review of pharmacokinetic and safety data from at least 
three volunteers with mild hepatic impairment and three volunteers with moderate hepatic 
impairment (Child-Pugh classification system) before volunteers with severely impaired hepatic 


Entrectinib—F. Hoffmann-La Roche Ltd
13/Protocol GP41174, Version 2
function are enrolled. Recruitment of volunteers with severely impaired hepatic function will only 
proceed if there is agreement between the Sponsor and the Investigator that data from this group 
are necessary to fulfil the objectives of the study and that dosing is not anticipated to present an 
unacceptable risk to those individuals.
The control group of volunteers with normal hepatic function will be enrolled after the full 
complement of volunteers with hepatic dysfunction has been dosed. The Normal group will be 
matched with the hepatically impaired volunteers with respect to sex, age and weight. The 
control group will include volunteers within the range of the hepatically impaired volunteers 
(extremes covered as far as possible), with approximately 50% of volunteers on each side of the 
median.
The study treatments will be administered orally as 1 x 100 mg F06 capsule, and given with 
approximately 240 mL of water within 30 minutes of consumption of a standardized meal.
Blood samples for measurement of plasma concentrations of entrectinib and its active metabolite 
M5 will be collected before and at intervals up to 144 hr after study drug dosing. In addition, 
samples will be taken for ex vivo measurement of plasma protein binding. Safety and tolerability 
will be monitored by clinical and laboratory assessments at intervals throughout the study.
Length of Study
The total duration of the study for each enrolled volunteer (screening through to end of study) will 
be up to 7 weeks, divided as follows:

Screening: up to 28 days before the first dose of study drug

One treatment period

Safety follow-up: 11 to 13 days after first study drug administration
Study participants will be resident in the study centre from Day -1 until at least Day 3, although 
the timing of admission and discharge is at the discretion of the Investigator and individuals may 
remain resident until Day 7. Volunteers will also have ambulatory study centre visits at Screening 
and Follow-up, and Days 4, 5 and 7 as appropriate.
PARTICIPANT POPULATION
Inclusion Criteria:
Volunteers must fulfill the following inclusion criteria to be eligible for participation in the study:
All volunteers
1.
Male or female
2.
Aged 18 to 75 years of age, inclusive, at screening.
3.
A body mass index (BMI) between 18.0 and 38.0 kg/m2, and weighing at least 50 kg, 
at screening.

Entrectinib—F. Hoffmann-La Roche Ltd
14/Protocol GP41174, Version 2
Additional criteria for volunteers with normal hepatic function:
6.
Normal hepatic function and no history of clinically significant hepatic dysfunction.
7.
Healthy for age-group in the opinion of the Investigator. Assessment of health status 
is based on a detailed medical history, physical examination, vital signs and 12-lead 
ECG assessment, and laboratory safety test results. Concurrent chronic disorders 
such as hypertension and diabetes are permissible providing they are stable and 
adequately controlled.
Additional criteria for volunteers with hepatic impairment
8.
Mild, moderate or severe hepatic dysfunction (i.e. Child-Pugh A, B or C, NCI-ODWG 
Mild, Moderate or Severe) arising from cirrhosis of the liver as the result of 
parenchymal liver disease. Cirrhosis should be documented by relevant laboratory 
test results and medical history, including confirmation of the diagnosis by liver 
biopsy, hepatic ultrasound, computerized tomography scan or magnetic resonance 
imaging scan.
9.
Stable hepatic function. Stable hepatic function is defined as no recent (i.e. within the 
preceding 14 days) clinically significant change in disease status according to the 
Investigator’s clinical judgment (e.g., no worsening of clinical signs of hepatic 
impairment, or no worsening of total bilirubin or prothrombin by more than 50%).
Exclusion Criteria:
Participants are not eligible for the study if any of the following criteria are met:
All volunteers
1.
Transjugular intrahepatic portosystemic shunt or other porta-caval shunt.
2.
A history of gastrointestinal hemorrhage due to esophageal varices or peptic ulcers 
within the three months preceding screening.
3.
Recent history (i.e. within the last 6 months prior to screening) or signs of severe 
hepatic encephalopathy (e.g., a portal systemic encephalopathy score >2).
4.
Advanced ascites or ascites which require emptying and albumin supplementation, 
as judged by the Investigator
5.
Hepatocellular carcinoma, acute liver disease (e.g., caused by an infection or drug 
toxicity) or serum ALT or AST at screening not consistent with stable disease in the 
opinion of the Investigator.
6.
Recipient of a liver transplant.
7.
Uncontrolled hypertension, defined as systolic blood pressure 160 mmHg and/or 
diastolic blood pressure 105 mmHg, considered clinically significant by the 
Investigator.
8.
Clinically significant impairment of renal function, defined as a creatinine clearance of 
<60 mL/min estimated from serum creatinine concentrations using Cockcroft-Gault 
equation.


Entrectinib—F. Hoffmann-La Roche Ltd
15/Protocol GP41174, Version 2
9.
A history of gastrointestinal surgery (e.g. gastric bypass) or other gastrointestinal 
disorder (e.g. malabsorption syndrome) that might affect absorption of medicines 
from the gastrointestinal tract. Cholecystectomy is permissible. 
10. Clinically significant change in health status, as judged by the Investigator, or any 
major illness within the four weeks before screening, or clinically significant acute 
infection or febrile illness within the 14 days before screening.
11. Apart from hepatic dysfunction, any other ongoing condition or disease, or laboratory 
test result, that the Investigator considers would render the participant unsuitable for 
the study, place the volunteer at undue risk, interfere with the ability of the volunteer
to complete the study (e.g. short life expectancy), or confound interpretation of study 
data. Concurrent chronic disorders such as hypertension and diabetes are 
permissible providing they are stable and adequately controlled.
12. Women who are pregnant or lactating.
13. Heart-rate corrected QT interval (QTcF) >480 msec or the presence of any other 
abnormal ECG finding, which, in the Investigator’s opinion, is clinically significant.
14. Use of moderate or potent inhibitors or inducers of cytochrome P450 3A4 enzyme 
within the 28 days before screening.
15. Participation in any other clinical study involving an investigational medicinal product 
or device within 28 days before screening.
16. A positive test result for human immunodeficiency virus (HIV).
17. Recent history (i.e. within the last 6 months prior to screening) of alcoholism, drug 
abuse, or drug addiction, or a positive test for alcohol or drugs of abuse. Alcohol 
consumption not exceeding 21 units for men and 14 units for women per week (1 unit 
equals 250 mL of beer, 75 mL of wine, or 25 mL of spirits) is permitted, although 
volunteers should not consume alcohol in the 48 hours preceding study center visits 
or during the period of in-patient confinement.
18. Known history of clinically significant hypersensitivity, or severe allergic reaction, to 
entrectinib or related compounds or other excipients in the entrectinib formulation.
19. Donation or loss of over 500 mL of blood within the three months before screening.
NUMBER OF PARTICIPANTS
It is planned that approximately 24 volunteers will be enrolled, with a target of six in each hepatic 
function group. The actual number enrolled will be determined by the Sponsor during the study 
from review of emerging data to ensure that at least six individuals are recruited in each hepatic 
function group for both classification systems, i.e. additional volunteers will be recruited if 
differences between the two categorization systems mean that there are fewer than six evaluable 
individuals in any hepatic function analysis group. Volunteers who withdraw from the study 
before Day 7 may also be replaced to ensure that at least six volunteers in each group have 
evaluable pharmacokinetic data.
No formal sample size calculations were performed. Six volunteers per group is consistent with 
recommendations in US and European regulatory guidelines [3, 4]. Based on the observed 
variability in entrectinib exposure parameters in previous clinical studies (e.g. AUCinf CV% 9-34% 


Entrectinib—F. Hoffmann-La Roche Ltd
16/Protocol GP41174, Version 2
from F06 capsules in healthy volunteers under fed conditions) six volunteers per group is 
considered appropriate to estimate the magnitude of the effect of hepatic impairment on 
entrectinib pharmacokinetic parameters.
PERMITTED AND PROHIBITED CONCOMITANT MEDICATIONS
Concurrent administration of drugs used to manage hepatic dysfunction and related disorders 
are permitted providing there has been no alteration to the treatment regimen within one week
preceding screening and the dosing regimen is not anticipated to change during the study. 
Similarly, other medications for chronic conditions (e.g. diabetes, hypertension) are permitted 
providing the volunteer has been on a stable dose and dosing regimen for at least one month 
preceding screening. However, the following categories of medication are specifically prohibited:

Moderate or potent inhibitors or inducers of CYP3A enzymes.
Volunteers should not consume grapefruit or Seville oranges during the study. During periods of 
in-patient residency volunteers will also be required to refrain from smoking, abstain from 
consumption of alcohol, and follow restrictions on consumption of food and beverages containing 
caffeine/xanthines, according to standard practices for the study center.
Women of child-bearing potential will be required to remain abstinent or use a highly effective 
method of contraception throughout the study and for 5 weeks after the last study treatment.
Women must refrain from donating eggs during this same period. Men with female partners of 
child-bearing potential must agree to remain abstinent or use barrier contraception throughout 
the study and for 3 months after the last study treatment. Men whose female partners are 
pregnant must also use barrier contraception throughout the study to avoid potential exposure 
of the fetus to the study drug. All men must also refrain from donating sperm during the study
and for 3 months after the last study treatment.
STATISTICAL ANALYSIS
Plasma concentrations of entrectinib and its active metabolite M5, and derived plasma 
pharmacokinetic parameters, will be listed and summarized by group using descriptive statistics. 
Individual and mean concentration versus time profiles will be plotted. Separate summaries will 
be presented for groups categorized according to the Child Pugh and NCI-ODWG system for 
classifying hepatic function. In effect there may be eight analysis groups (i.e. Normal Child-Pugh, 
Normal NCI-ODWG, Mild Child-Pugh, Mild NCI-ODWG, Moderate Child-Pugh, Moderate NCI-
ODWG, Severe Child-Pugh, and Severe NCI-ODWG).
The following pharmacokinetic parameters will be derived using standard non-compartmental 
methods: 

Cmax:  Maximum observed plasma concentration

AUClast: Area under the plasma entrectinib concentration-time curve from time 0 to the 
last measurable concentration.

AUCinf:  Area under the plasma entrectinib concentration-time curve from time 0 
extrapolated to infinity.

Tmax:  Time of maximum observed plasma concentration

λz:  Apparent terminal elimination rate constant

t1/2:  Apparent terminal elimination half-life

M:P ratio:  Molecular weight-adjusted metabolite to parent ratio based on AUCinf

CL/F:  Apparent oral clearance (entrectinib only)

V/F:  Apparent volume of distribution (entrectinib only) 

fu:  Fraction of drug unbound in plasma


Entrectinib—F. Hoffmann-La Roche Ltd
17/Protocol GP41174, Version 2
The fractions of entrectinib and M5 unbound in plasma (fu) will be determined by ex vivo protein 
binding assay and used to calculate exposure parameters adjusted for protein binding (i.e., 
unbound Cmax, unbound AUCinf).
An analysis of variance (ANOVA) will be used to estimate the effect of hepatic impairment on 
log-transformed total and unbound entrectinib and M5 exposure parameters and will include the 
factor hepatic impairment (i.e. mild, moderate and severe, and none). Estimates of geometric 
mean ratios on the original scale, together with the corresponding 90% confidence intervals 
(CIs), will be derived for the comparisons between each hepatic impairment group and the 
control group with normal hepatic function. Duplicate analyses will be performed for groups 
based on Child-Pugh and NCI-ODWG classifications.
The relationship between entrectinib pharmacokinetic parameters (e.g. Cmax and AUCinf) and 
measures of hepatic function (e.g., Child-Pugh scores, albumin, bilirubin, or AST concentrations, 
prothrombin time etc.) will be explored using linear or non-linear models or regression analyses, 
as appropriate.

BACKGROUND
Entrectinib (RO7102122, formerly known as RXDX-101) is a potent and selective 
inhibitor of TRKA, TRKB, TRKC, ROS1, and ALK receptor tyrosine kinases. 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 [5, 6]. Therefore, these kinases represent attractive targets for 
anticancer therapy and approval is currently being sought for use of entrectinib in adults 
and children for oncology indications.
Refer to the Investigator’s Brochure (IB) for detailed background information on 
entrectinib and for details on nonclinical and clinical studies.
1.1
BACKGROUND ON ENTRECTINIB
1.1.1
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.
1.1.2
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 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 (hERG) 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—F. Hoffmann-La Roche Ltd
21/Protocol GP41174, Version 2
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.
1.1.3
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 with immediate release capsules (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 clinically relevant effect on entrectinib oral bioavailability from capsule 
formulations (Figure 1).
Figure 1:
Median entrectinib plasma concentration versus time profile 
following a single 600 mg dose to healthy volunteers under fed or fasted 
conditions
Source: Study RXDX-101-154 CSR Figure 14.3.
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 


Entrectinib—F. Hoffmann-La Roche Ltd
22/Protocol GP41174, Version 2
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 and in vivo drug-drug interaction studies entrectinib was a weak inhibitor of 
CYP3A enzyme activity. Although in vitro studies suggest entrectinib is a poor P-
glycoprotein (P-gp) substrate and has weak inhibitory effects on selected drug 
transporters, clinically relevant interactions are not anticipated in vivo.
1.1.4
Clinical Program
The clinical program to date includes 10 completed 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.

safety findings.
1.2
STUDY RATIONALE AND BENEFIT-RISK ASSESSMENT
1.2.1
Study Rationale
In vitro studies indicate that the clearance of entrectinib is predominantly through hepatic 
metabolism, and that entrectinib is primarily metabolized by cytochrome P450 3A4 
(CYP3A4) with minor contributions from several other cytochrome P450 enzymes and 
UDP-glucuroyltransferase 1A4 (UGT1A4). Furthermore, co-administration of a strong 
CYP3A4 inhibitor (itraconazole), increased entrectinib total exposure by approximately 
5-fold while co-administration of a strong inducer (rifampin) decreased entrectinib total 
exposures by approximately 77%. Thus the results indicate that entrectinib is a sensitive 
substrate of CYP3A4 and hence impairment of liver function has the potential to alter 
exposure of entrectinib and its major active metabolite M5. As entrectinib is likely to be 
administered to patients with hepatic dysfunction, a pharmacokinetic study in individuals 
with reduced hepatic function is required according to US and European regulatory 
guidelines [3, 4]. The aim of this study is therefore to quantify the effect of hepatic 
impairment on the pharmacokinetics of entrectinib and thereby underwrite dosing 
recommendations for use of entrectinib in patients with reduced hepatic function.
1.2.2
Benefit-Risk Assessment
There will be no therapeutic benefit for the volunteers 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 up to 800 mg to healthy subjects has been characterized 
from previous clinical studies. There have been few AEs following entrectinib dosing in 


Entrectinib—F. Hoffmann-La Roche Ltd
25/Protocol GP41174, Version 2
previous clinical studies in healthy volunteers and no specific safety concerns have been 
identified about the use of 100 mg entrectinib in volunteers with impaired hepatic 
function in this study. Of the 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 highly effective 
contraception throughout the study. In addition, woman need to use highly effective 
contraception for 5 weeks after cessation of entrectinib treatment and men with female 
partners of childbearing potential or female partners who are pregnant need to use 
highly effective contraception for 3 months after last study treatment.
Overall, no significant safety concerns have been identified about the use of 100 mg 
entrectinib in volunteers with impaired hepatic function. All volunteers will be resident in 
the study center and remain under medical supervision following study drug 
administration and will undergo a standard battery of safety assessments. Hence, the 
risks to participants in this study are considered acceptable.

STUDY DESIGN
3.1
DESCRIPTION OF THE STUDY
This is a non-randomized, open-label, one treatment, four group, parallel group study to 
investigate the effect of impaired hepatic function on the pharmacokinetics of entrectinib 
in volunteers with different levels of hepatic function. Volunteers with mild, moderate or 
severe hepatic impairment (‘Mild’, ‘Moderate’ and ‘Severe’ groups), and control
volunteers with normal hepatic function (‘Normal’ group) will each receive a single 100 
mg dose of entrectinib after consumption of a standardized meal. A representation of the 
study design is provided in Figure 2.
Volunteers with reduced hepatic function will be assigned to a functional category based 
on assessments at the Screening visit. Each individual will be categorized according to 
the Child Pugh system for classifying hepatic impairment (Table 3) and also according to 
the National Cancer Institute (NCI) organ dysfunction working group (NCI-ODWG) 
system (Table 4).  Sufficient volunteers will be enrolled to ensure that at least six 
individuals are recruited in each hepatic function group for both classification systems
(see Section 6.1 ).
Recruitment will be staggered to allow review of pharmacokinetic and safety data from at 
least three volunteers in each of the Mild and Moderate groups before volunteers are 
enrolled into the Severe group. Recruitment of the Severe group will only proceed if 
there is agreement between the Sponsor and the Investigator that data from this group 
are necessary to fulfill the objectives of the study and that dosing is not anticipated to 
present an unacceptable risk to those individuals.
The control group of volunteers with normal hepatic function will be enrolled after the full 
complement of volunteers with hepatic dysfunction has been dosed. The Normal group 
will be matched with the hepatically impaired volunteers with respect to sex, age and 
weight. The control group will include volunteers within the range of the hepatically 
impaired volunteers (extremes covered as far as possible), with approximately 50% of 
volunteers on each side of the median.

Overview of study design
Schematic not to scale
The study treatment will be administered orally as 1 x 100 mg F06 capsule, and given 
with approximately 240 mL of water within 30 minutes after consumption of a 
standardized meal.
Blood samples for measurement of plasma concentrations entrectinib and its active 
metabolite M5 will be collected before and at intervals up to 144 hr after study drug 
dosing. In addition, samples will be taken for ex vivo measurement of plasma protein 
binding. Safety and tolerability will be monitored by clinical and laboratory assessments 
at intervals throughout the study.
Study participants will be resident in the study center from Day -1 until at least Day 3, 
although the timing of admission and discharge is at the discretion of the Investigator 
and individuals may remain resident until Day 7. Volunteers will also have ambulatory 
study center visits at Screening and Follow-up, and Days 4, 5 and 7 as appropriate.
Patients who do not meet the criteria for participation in this study (screen failure) 
cannot be re-screened.  The investigator will record reasons for screen failure in the 
screening log (see Section 4.5.1).
3.2
END OF STUDY AND LENGTH OF STUDY
The total duration of the study for each enrolled volunteer (screening through to end of 
study) is expected to be approximately 8 weeks, divided as follows:

Screening: up to 28 days before the first dose of study drug

One treatment period

Safety follow-up: 11 to 13 days after first study drug administration
The end of study is defined as the date of the last scheduled study procedure for the last
participating volunteer. In addition, the Sponsor may decide to terminate the study at any 
time.

3.3
RATIONALE FOR STUDY DESIGN
3.3.1
Rationale for Entrectinib Dose and Schedule
A single 100 mg dose will be administered to each participant. The recommended dose 
of entrectinib for cancer patients is 600 mg once daily and 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. A lower dose of 
entrectinib has been chosen for this study because of the anticipated effect of hepatic 
impairment on entrectinib pharmacokinetics.  Although first pass clearance of entrectinib 
appears negligible and it is not anticipated that peak exposure from a single dose will be 
significantly altered by hepatic dysfunction, any reduction in systemic clearance has the 
potential to markedly increase total exposure.  Selection of a low dose allows the same 
dose to be used in all categories of hepatic function without compromising individual
safety, while still permitting full characterization of entrectinib and M5 pharmacokinetics 
in all groups.
It is anticipated that severe impairment of liver function will lead to an increase in 
entrectinib exposure comparable to the magnitude of the drug-drug interaction observed 
when a potent CYP3A4 inhibitor is co-administered with entrectinib 
(Study RXDX-101-12. Figure 3 and Table 2). When a single 100 mg dose of entrectinib 
was co-administered with the potent CYP3A4 inhibitor itraconazole, entrectinib total 
exposure was increased approximately 500% but remained similar to that from a single 
600 mg entrectinib dose administered alone (e.g. Figure 1).

Study drug administration will be with food.  Typically, pharmacokinetic studies are 
conducted while fasted but many hepatically impaired patients are diabetic and would 
thus be unable to comply with a standard fasting regimen. Giving entrectinib with food
also matches dosing instructions for patients in pivotal and supportive clinical trials, 
which recommend administering entrectinib within 30 minutes following a meal.
3.3.2
Rationale for Patient Population
The study will recruit volunteers with impaired hepatic function arising from liver cirrhosis 
and matched controls with normal hepatic function. Hepatic function will be assessed 
using two widely accepted functional categorization systems (Child Pugh, see Table 3; 
NCI-ODWG, see Table 4). Cirrhosis is to be confirmed by independent diagnostic 
procedures. The two categorization systems will be used in parallel because, while 
regulatory guidelines on assessment of the effect of hepatic impairment on drug 
pharmacokinetics recommend use of Child Pugh categorization [3, 4], entrectinib is 
intended for use in oncology indications and the NCI-ODWG system is considered most 
relevant for prescribers.
3.3.3
Rationale for Study Design
The aim of the study is to estimate the effect of hepatic impairment on the 
pharmacokinetics of entrectinib with the intention of underwriting recommendations for 
the safe use of entrectinib in patients with hepatic dysfunction. This will be achieved by 
comparison of entrectinib single dose pharmacokinetic parameters between groups of 
volunteers with reduced hepatic function and a demographically matched control group 


Entrectinib—F. Hoffmann-La Roche Ltd
30/Protocol GP41174, Version 2
of healthy volunteers with normal hepatic function. The study design follows the 
principles described in regulatory guidelines for investigating the effects of hepatic 
impairment on investigational compounds [3, 4]. Two designs are suggested in 
regulatory guidelines: a 'full' study design including volunteers with normal hepatic 
function (control) and mild, moderate and severe hepatic impairment, and a 'reduced' 
study design including volunteers with normal hepatic function (control) and moderate 
hepatic impairment. A ‘full’ study design has been selected because the intended 
indications for entrectinib make it likely to be used in patients with significant hepatic 
dysfunction.
A single dose design is considered appropriate to explore the effect of hepatic 
impairment because entrectinib pharmacokinetics are not time dependent and single 
dose pharmacokinetics are predictive of steady state pharmacokinetics. This study is not 
blinded because it is not believed that knowledge of the treatment administered will 
introduce bias into the assessment of entrectinib pharmacokinetics.
3.3.4
Rationale for Assessments
The pharmacokinetic sampling schedule has been selected on the basis of data from 
previous studies in which single doses of entrectinib have been administered to healthy 
volunteers and patients. Specifically, the entrectinib and M5 pharmacokinetic profiles 
observed when entrectinib was co-administered with itraconazole (Study RXDX-101-12) 
were used to inform the pharmacokinetic sampling schedules. The frequency and 
duration of plasma sampling is considered to be sufficient to accurately estimate relevant 
pharmacokinetic parameters in all hepatic function groups; it is considered that sampling 
out to 144 hr after dosing will allow adequate characterization of the terminal phase of 
entrectinib even in individuals with severe hepatic impairment. The pharmacokinetic
parameters to be derived and subject to statistical analysis are consistent with the 
relevant regulatory guidelines [3, 4]. Samples will also be taken from all participants to 
allow estimation of protein binding and thereby permit comparisons of unbound 
pharmacokinetic parameters.
Although it is potentially of interest to explore whether the contribution of renal clearance 
to total clearance is affected by hepatic dysfunction, data from healthy subjects indicate 
that very little entrectinib or M5 is excreted unchanged into the urine. It is therefore 
unlikely that measurement of entrectinib concentrations in urine would allow any 
meaningful conclusions to be drawn. For this reason, there will be no urine collection 
during the study.

MATERIALS AND METHODS
4.1
POPULATION
The study will enroll male and female volunteers with mild, moderate or severe hepatic 
impairment and control volunteers with normal hepatic function.
4.1.1
Inclusion Criteria
Volunteers must fulfill the following inclusion criteria to be eligible for participation in the 
study:
All volunteers
1. Male or female
2. Aged 18 to 75 years of age, inclusive, at screening.
3. A body mass index (BMI) between 18.0 and 38.0 kg/m2, and weighing at 
least 50 kg, at screening.
4. Agreement to comply with measures to prevent pregnancy and restrictions on 
sperm donation.
5. Able and willing to give written informed consent and to comply with study 
protocol and study restrictions.
Additional criteria for volunteers with normal hepatic function
6. Normal hepatic function and no history of clinically significant hepatic 
dysfunction.
7. Healthy for age-group in the opinion of the Investigator. Assessment of health 
status is based on a detailed medical history, physical examination, vital 
signs and 12-lead ECG assessment, and laboratory safety test results. 
Concurrent chronic disorders such as hypertension and diabetes are 
permissible providing they are stable and adequately controlled.
Additional criteria for Volunteers with hepatic impairment
8. Mild, moderate or severe hepatic dysfunction (i.e. Child-Pugh A, B or C, NCI-
ODWG Mild, Moderate or Severe) arising from cirrhosis of the liver as the 
result of parenchymal liver disease. Cirrhosis should be documented by 
relevant laboratory test results and medical history, including confirmation of 
the diagnosis by liver biopsy, hepatic ultrasound, computerized tomography 
(CT) scan or magnetic resonance imaging (MRI) scan.
9. Stable hepatic function. Stable hepatic function is defined as no recent (i.e. 
within the preceding 14 days) clinically significant change in disease status 
according to the Investigator’s clinical judgment (e.g., no worsening of clinical 
signs of hepatic impairment, or no worsening of total bilirubin or prothrombin 
by more than 50%).


Entrectinib—F. Hoffmann-La Roche Ltd
32/Protocol GP41174, Version 2
4.1.2
Exclusion Criteria
Volunteers are not eligible for the study if any of the following criteria are met:
All volunteers
1. Transjugular intrahepatic portosystemic shunt or other porta-caval shunt.
2. A history of gastrointestinal hemorrhage due to esophageal varices or peptic 
ulcers within the three months preceding screening.
3. Recent history (i.e. within the last 6 months prior to screening) or signs of 
severe hepatic encephalopathy (e.g., a portal systemic encephalopathy score 
>2).
4. Advanced ascites or ascites which require emptying and albumin 
supplementation, as judged by the Investigator.
5. Hepatocellular carcinoma, acute liver disease (e.g., caused by an infection or 
drug toxicity) or serum ALT or AST at screening not consistent with stable 
disease in the opinion of the Investigator.
6. Recipient of a liver transplant.
7. Uncontrolled hypertension, defined as SBP 160 mmHg and/or DBP 105 
mmHg, considered clinically significant by the Investigator.
8. Clinically significant impairment of renal function, defined as a creatinine 
clearance of <60 mL/min estimated from serum creatinine concentrations 
using Cockcroft-Gault equation.
9. A history of gastrointestinal surgery (e.g. gastric bypass) or other 
gastrointestinal disorder (e.g. malabsorption syndrome) that might affect 
absorption of medicines from the gastrointestinal tract. Cholecystectomy is 
permissible. 
10. Clinically significant change in health status, as judged by the Investigator, or 
any major illness within the four weeks before screening, or clinically 
significant acute infection or febrile illness within the 14 days before 
screening.
11. Apart from hepatic dysfunction, any other ongoing condition or disease, or 
laboratory test result, that the Investigator considers would render the 
participant unsuitable for the study, place the volunteer at undue risk, 
interfere with the ability of the volunteer to complete the study (e.g. short life 
expectancy), or confound interpretation of study data. Concurrent chronic 
disorders such as hypertension and diabetes are permissible providing they 
are stable and adequately controlled.

finding, which, in the Investigator’s opinion, is clinically significant.
14. Use of moderate or potent inhibitors or inducers of cytochrome P450 3A4 
enzyme within the 28 days before screening.
15. Participation in any other clinical study involving administration of an 
investigational medicinal product or use of an unapproved device within 28 
days before screening.
16. A positive test result for human immunodeficiency virus (HIV).
17. Recent history (i.e. within the last 6 months prior to screening) of alcoholism, 
drug abuse, or drug addiction, or a positive test for alcohol or drugs of abuse. 
Alcohol consumption not exceeding 21 units for men and 14 units for women 
per week (1 unit equals 250 mL of beer, 75 mL of wine, or 25 mL of spirits) is 
permitted, although volunteers should not consume alcohol in the 48 hrs 
preceding study center visits or during the period of in-patient confinement.
18. Known history of clinically significant hypersensitivity, or severe allergic 
reaction, to entrectinib or related compounds or other excipients in the 
entrectinib formulation.
19. Donation or loss of over 500 mL of blood within the three months before 
screening.
4.2
METHOD OF TREATMENT ASSIGNMENT AND BLINDING
This is a non-randomized, open label study. All volunteers will receive the same study 
drug treatment (i.e. a single 100 mg dose of entrectinib).
Volunteers with reduced hepatic function will be assigned to a functional category based 
on assessments at the Screening visit. Each individual will be categorized according to 
the Child Pugh system for classifying hepatic impairment (Table 3) and also according to 
the National Cancer Institute (NCI) organ dysfunction working group (NCI-ODWG) 
system (Table 4).

by qualified study site employees. Each unit dose container will be appropriately labeled.
4.3.2
Study Treatment Dosage, Administration, and Compliance
Each volunteer will receive a single 100 mg dose of entrectinib with food. The study 
treatment will be administered orally as 1 x 100 mg F06 capsule, and given with 
approximately 240 mL of water within 30 minutes of consumption of a standardized 
meal.
Cases of accidental overdose or medication error, along with any associated AEs, 
should be reported as described in Section 5.4.4. This is a single dose study and dose 
modification or treatment interruption is not possible. Guidelines for clinical management 
of individuals who experience AEs are provided in Section 5.1.
4.3.3
Investigational Medicinal Product Accountability
All IMPs required for completion of this study (entrectinib) will be provided by the 
Sponsor where required by local health authority regulations.  The study site will 
acknowledge receipt of IMPs supplied by the Sponsor by returning the appropriate 
documentation form to confirm the shipment condition and content.  Any damaged 
shipments will be replaced.
IMPs will either be disposed of at the study site according to the study site's institutional 
standard operating procedure or be returned to the Sponsor (if supplied by the Sponsor) 
with the appropriate documentation.  The site's method of destroying Sponsor-supplied 
IMPs must be agreed to by the Sponsor.  The site must obtain written authorization from 
the Sponsor before any Sponsor-supplied IMP is destroyed, and IMP destruction must 
be documented on the appropriate form.


Entrectinib—F. Hoffmann-La Roche Ltd
36/Protocol GP41174, Version 2
Accurate records of all IMPs received at, dispensed from, returned to, and disposed of by 
the study site should be recorded on the Drug Inventory Log.
4.3.4
Continued Access to Entrectinib
Currently, the Sponsor does not have any plans to provide entrectinib to volunteers who 
have completed the study.
4.4
CONCOMITANT THERAPY, PROHIBITED FOOD AND 
ADDITIONAL RESTRICTIONS
4.4.1
Concomitant Therapy
Concomitant therapy consists of any medication (e.g., prescription drugs, over-the-
counter drugs, vaccines, herbal or homeopathic remedies, nutritional supplements) used 
by an individual in addition to protocol-mandated treatment from 7 days prior to study 
drug treatment to the end of the study.  All such medications should be reported to the 
Investigator and recorded on the eCRF.
Concurrent administration of drugs used to manage hepatic dysfunction and related 
disorders are permitted providing there has been no alteration to the treatment regimen 
within one week preceding screening and the dosing regimen is not anticipated to 
change during the study. Similarly, other medications for chronic conditions (e.g. 
diabetes, hypertension) are permitted providing the volunteer has been on a stable dose 
and dosing regimen for at least one month preceding screening. However, use of the 
following categories of medication are specifically prohibited (see Appendix 2 for 
examples):

Moderate or potent inhibitors or inducers of CYP3A enzymes.
4.4.2
Contraception
Women of childbearing potential must agree to remain abstinent (i.e. refrain from 
heterosexual intercourse) or use a highly-effective method of contraception (failure rate 
of <1% per year) throughout the study and for 5 weeks after the last study treatment.
Women must refrain from donating eggs during this same period. Examples of 
contraceptive methods with a failure rate of 1% per year include bilateral tubal ligation, 
male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing 
intrauterine devices, and copper intrauterine devices.
A woman is considered to be of childbearing potential if she is postmenarcheal but has 
not reached a postmenopausal state, and has not undergone surgical sterilization. 
Postmenopausal is defined as at least 12 months without a period (i.e., amenorrhea) in a 
female at least 45 years of age and accompanied by a serum follicle-stimulating 
hormone [FSH] level judged by the Investigator to be consistent with postmenopausal 
status 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.


Entrectinib—F. Hoffmann-La Roche Ltd
37/Protocol GP41174, Version 2
Men with female partners of child-bearing potential must agree to remain abstinent (i.e. 
refrain from heterosexual intercourse) or use barrier contraception throughout the study
and for 3 months after the last study treatment.  Men whose female partners are 
pregnant must also use barrier contraception throughout the study and for 3 months 
after the last study treatment to avoid potential exposure of the fetus to the study drug. 
All men must also refrain from donating sperm during the study and for 3 months after
the last study treatment.
Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) 
and withdrawal are not acceptable methods of contraception.
For volunteers who are exclusively in same-sex relationships or are abstinent (when this 
is in line with the preferred and usual lifestyle of the volunteer), contraceptive 
requirements do not apply. If a volunteer 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.
The reliability of sexual abstinence should be evaluated in relation to the duration of the 
clinical trial and the preferred and usual lifestyle of the volunteer. Periodic abstinence 
(e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are 
not acceptable methods of contraception. 
4.4.3
Food
Volunteers should not consume grapefruit or Seville oranges during the study. During 
periods of in-patient residency, volunteers will also be required to refrain from using 
tobacco- or nicotine-containing products (including, but not limited to, cigarettes, e-
cigarettes, pipes, cigars, chewing tobacco, nicotine patches, nicotine lozenges, and 
nicotine gum), abstain from consumption of alcohol, and follow restrictions on 
consumption of food and beverages containing caffeine/xanthines, according to standard 
practices for the study center.
While resident in the study center, volunteers will receive a standardized diet at 
scheduled times that do not conflict with other study-related activities.
4.4.4
Additional Restrictions
Volunteers should refrain from strenuous exercise from 48 hours prior to admission to 
the study center and during the period of confinement 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).
4.5
STUDY ASSESSMENTS 
The schedule of activities to be performed during the study is provided in Appendix 1.  
All activities should be performed and documented for each individual study participant. 


Entrectinib—F. Hoffmann-La Roche Ltd
38/Protocol GP41174, Version 2
Assessments will be made at specified times relative to study drug dosing, though in 
each case the actual times of assessment will also be recorded in the eCRF.
At time points when assessments coincide; procedures will be performed in the following 
order: AE and concomitant medication monitoring, 12-lead ECG and vital signs,
pharmacokinetic blood sampling.
4.5.1
Informed Consent Forms and Screening Log
Written informed consent for participation in the study must be obtained before 
performing any study-related procedures (including screening evaluations).  Informed 
Consent Forms (ICFs) for enrolled volunteers and for volunteers who are not 
subsequently enrolled will be maintained at the study site.
All screening evaluations must be completed and reviewed to confirm that volunteers 
meet all eligibility criteria before enrollment.  The Investigator will maintain a screening 
log to record details of all volunteers screened and to confirm eligibility or record reasons 
for screening failure, as applicable.
4.5.2
Medical History, Concomitant Medication, and Demographic 
Data
Medical history, including clinically significant diseases, surgeries, cancer history 
(including prior cancer therapies and procedures), reproductive status, and use of 
alcohol and drugs of abuse, will be recorded at screening.  In addition, all medications 
(e.g., prescription drugs, over-the-counter drugs, vaccines, herbal or homeopathic 
remedies, nutritional supplements) used by the volunteer within seven days prior to 
study drug treatment will be recorded.  At the time of each follow-up physical 
examination, an interval medical history should be obtained and any changes in 
medications and allergies should be recorded.
Demographic data will include age, sex, and self-reported race/ethnicity.
4.5.3
Physical Examinations
A complete physical examination performed at screening should include an evaluation of 
the head, eyes, ears, nose, and throat, and the cardiovascular, dermatologic, 
musculoskeletal, respiratory, gastrointestinal, and neurologic systems.  Any abnormality 
identified at baseline should be recorded on the eCRF.
A brief physical examination on admission to the study centre on Day -1 and at follow-
up. Symptom-driven physical examinations may be performed at other times at the 
Investigator’s discretion.  Changes from baseline abnormalities should be recorded.  
New or worsened clinically significant abnormalities should be recorded as AEs on the 
eCRF.


Entrectinib—F. Hoffmann-La Roche Ltd
39/Protocol GP41174, Version 2
4.5.4
Vital Signs
Vital signs will be measured at specified time-points as outlined in the schedule of 
activities (see Appendix 1 ). Vital signs will include measurements of respiratory rate, 
pulse rate, and systolic and diastolic blood pressure while the volunteer is in a supine
position (see Section 4.5.6), and temperature.
4.5.5
Laboratory Samples
For sampling and processing procedures, storage conditions, and shipment instructions, 
see the laboratory manual. All biological samples will be destroyed when the final 
Clinical Study Report has been completed.
When a volunteer withdraws from the study, samples collected prior to the date of 
withdrawal may still be analyzed, unless the volunteer specifically requests 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.
Screening blood samples, including those collected from patients who do not enroll in 
the study, may be used for future research and/or development of disease-related tests or 
tools.
Data arising from sample analysis will be subject to the confidentiality standards 
described in Section 8.4.
4.5.5.1
Pharmacokinetics
Blood samples for measurement of plasma concentrations 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 time-points detailed in the schedule of activities (see Appendix 1 ). In addition, a 
blood sample will also be collected for estimation of entrectinib and M5 plasma protein 
binding using an ex vivo protein binding assay (see Appendix 1 ).
Plasma concentrations of entrectinib and M5 will be determined using a validated liquid 
chromatography tandem mass spectrometry (LC-MS/MS) bioanalytical procedure at a 
bioanalytical laboratory designated by the Sponsor. Plasma unbound fractions of 
entrectinib and M5 will be determined by appropriate assays.
4.5.5.2
Laboratory Safety Tests
Blood samples for the following laboratory safety tests will be collected at the time-points 
detailed outlined in the schedule of activities (see Appendix 1 ).

Hematology: erythrocytes, leukocyte count with differential (neutrophils, 
eosinophils, lymphocytes, monocytes and basophils), hemoglobin, hematocrit, 
platelet count


Entrectinib—F. Hoffmann-La Roche Ltd
40/Protocol GP41174, Version 2

Coagulation: prothrombin time and international normalized ratio, and activated 
partial thromboplastin time

Serum biochemistry: sodium, potassium, chloride, glucose (fasting), urea, 
albumin, calcium, magnesium, inorganic phosphorus, ALP, AST, ALT, creatine 
phosphokinase, lactate dehydrogenase, serum creatinine, gamma glutamyl 
transferase, total and direct bilirubin, total protein, total cholesterol, HDL-C, LDL-
C, triglycerides and uric acid
Blood samples should be obtained following a fast of at least 4 hours.
In addition, urine samples will be collected for measurement of urinary protein, blood, 
glucose, leukocytes, pH and sediment. Urine samples that are positive may be sent for 
further follow-up microscopic examination (i.e. RBCs, WBCs, casts, crystals, epithelial 
cells, bacteria) as deemed appropriate by the Investigator.
4.5.5.3
Other
A blood sample for screening for HIV, hepatitis B (HBV) and hepatitis C (HCV) infection 
will be collected at the screening visit.
A urine screen for selected drugs of abuse will be performed at screening visit and 
repeated along with an alcohol breath test on admission to the study center (Day -1).
All women of childbearing potential will have a serum pregnancy test at screening. Urine 
pregnancy tests will be performed on admission to the study center (Day -1) and at the 
follow-up visit.  If a urine pregnancy test is positive, it must be confirmed by a serum 
pregnancy test.
Post-menopausal status should be confirmed by a FSH test at the screening visit as 
appropriate.
4.5.6
Electrocardiograms
Single ECG recordings will be obtained at specified time-points, as outlined in the 
schedule of activities (see Appendix 1 ), and may be obtained at unscheduled time-
points as indicated. 
All ECG recordings should be performed using a standard high-quality, high-fidelity 
digital electrocardiograph machine equipped with computer-based interval 
measurements.  Lead placement should be as consistent as possible.  ECG recordings 
must be performed after the volunteer has been resting in a supine position for at least 5 
minutes.  All ECGs are to be obtained prior to other procedures scheduled at that same 
time (e.g., vital sign measurements, blood draws).  Circumstances that may induce 
changes in heart rate, including environmental distractions (e.g., television, radio, 


Entrectinib—F. Hoffmann-La Roche Ltd
41/Protocol GP41174, Version 2
conversation) should be avoided during the pre-ECG resting period and during ECG 
recording.
For safety monitoring purposes, the Investigator must review, sign, and date all ECG 
tracings.  Paper copies of ECG tracings will be kept as part of the volunteer's permanent 
study file at the site. 
If at a particular post-dose time-point the mean QTcF is 500 ms and/or 60 ms 
longer than the baseline value, another ECG must be recorded, ideally within the next 
5 minutes, and ECG monitoring should continue until QTcF has stabilized on two 
successive ECGs.  The Medical Monitor should be notified.  Standard-of-care treatment 
may be instituted per the discretion of the Investigator. The Investigator should also 
evaluate the volunteer for potential concurrent risk factors (e.g., electrolyte 
abnormalities, co-medications known to prolong the QT interval, severe bradycardia).
4.6
TREATMENT, PATIENT, STUDY, AND SITE DISCONTINUATION
4.6.1
Patient Discontinuation from Study
Patients have the right to voluntarily withdraw from the study at any time for any reason.  
In addition, the Investigator has the right to withdraw a volunteer from the study at any 
time.  Reasons for withdrawal from the study may include, but are not limited to, the 
following:

Patient withdrawal of consent

Patient non-compliance, defined as failure to comply with protocol requirements as 
determined by the Investigator or Sponsor

Study termination or site closure
Every effort should be made to obtain information on volunteers who withdraw from the 
study but have not withdrawn consent.  The primary reason for withdrawal from the 
study should be documented on the eCRF.  If a volunteer requests to be withdrawn from 
the study, this request must be documented in the source documents and signed by the 
Investigator.  Patients who withdraw from the study may be replaced.
4.6.2
Study Discontinuation
The Sponsor has the right to terminate this study at any time. Reasons for terminating 
the study may include, but are not limited to, the following:

The incidence or severity of AEs in this or other studies indicates a potential health 
hazard to volunteers

Patient enrollment is unsatisfactory
The Sponsor will notify the Investigator if the Sponsor decides to discontinue the study.  


Entrectinib—F. Hoffmann-La Roche Ltd
42/Protocol GP41174, Version 2
A decision to not enroll volunteers with severely impaired hepatic function because the 
key pharmacokinetic objectives of the study have already been met will not be 
considered early termination of the study.
4.6.3
Site Discontinuation
The Sponsor has the right to close a site at any time.  Reasons for closing a site may 
include, but are not limited to, the following:

Excessively slow recruitment

Poor protocol adherence

Inaccurate or incomplete data recording

Non-compliance with the International Council for Harmonisation (ICH) guideline for 
Good Clinical Practice

No study activity (i.e., all volunteers have completed the study and all obligations 
have been fulfilled)
5.
ASSESSMENT OF SAFETY
5.1
SAFETY PLAN
Entrectinib is not approved in any European country at the time of writing, and clinical 
development is ongoing.  The safety plan for volunteers in this study is based on clinical 
experience with entrectinib in completed and ongoing studies.  The anticipated important 
safety risks for entrectinib are described in the entrectinib Investigator's Brochure. 
Several measures will be taken to ensure the safety of volunteers participating in this 
study.  Eligibility criteria have been designed to exclude volunteers at higher risk for 
toxicities.  Patients will undergo safety monitoring during the study, including 
assessment of the nature, frequency, and severity of AEs.
5.2
SAFETY PARAMETERS AND DEFINITIONS
Safety assessments will consist of monitoring and recording AEs, including serious AEs 
and AEs of special interest, 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.
Certain types of events require immediate reporting to the Sponsor, as outlined in 
Section 5.4.
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.


Entrectinib—F. Hoffmann-La Roche Ltd
43/Protocol GP41174, Version 2
5.2.1
Adverse Events
According to the ICH guideline for Good Clinical Practice, 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:

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) (see Sections 5.3.5.8 and 
5.3.5.9 for more information)

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)
5.2.2
Serious Adverse Events (Immediately Reportable to the 
Sponsor)
A serious AE 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 volunteer 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 (see Section 5.3.5.10)

Results in persistent or significant disability/incapacity (i.e., the AE results in 
substantial disruption of the volunteer'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 volunteer or may require medical/surgical intervention to prevent one of the 
outcomes listed above)
The terms "severe" and "serious" are not synonymous.  Severity refers to the intensity of 
an AE (e.g., rated as mild, moderate, or severe, or according to National Cancer Institute 
Common Terminology Criteria for Adverse Events [NCI CTCAE]; see Section 5.3.3); the 
event itself may be of relatively minor medical significance (such as severe headache 
without any further findings).


Entrectinib—F. Hoffmann-La Roche Ltd
44/Protocol GP41174, Version 2
Severity and seriousness 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 immediately 
(i.e., no more than 24 hours after learning of the event; see Section 5.4.2 for reporting 
instructions).
5.2.3
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 immediately (i.e., no more than 24 hours after learning of the event; see 
Section 5.4.2 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 ALT or AST in 
combination with either an elevated bilirubin or clinical jaundice, as defined by Hy's 
Law (see Section 5.3.5.6)

Suspected transmission of an infectious agent by the study drug, as defined below
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 patient exposed to a medicinal product.  This 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)
5.3
METHODS AND TIMING FOR CAPTURING AND ASSESSING 
SAFETY PARAMETERS
The Investigator is responsible for ensuring that all AEs (see Section 5.2.1 for definition) 
are recorded on the eCRF and reported to the Sponsor in accordance with instructions 
provided in this section and in Sections 5.45.6.
For each AE recorded on the eCRF, the Investigator will make an assessment of 
seriousness (see Section 5.2.2 for seriousness criteria), severity (see Section 5.3.3), and 
causality (see Section 5.3.4).  


Entrectinib—F. Hoffmann-La Roche Ltd

5.3.1
Adverse Event Reporting Period
Investigators will seek information on AEs at each volunteer contact.  All AEs, whether 
reported by the volunteer or noted by study personnel, will be recorded in the volunteer's 
medical record and on the eCRF.
After informed consent has been obtained but prior to initiation of study drug, only 
serious AEs caused by a protocol-mandated intervention (e.g., invasive procedures such 
as biopsies, discontinuation of medications) should be reported (see Section 5.4.2 for 
instructions for reporting serious AEs).
After initiation of study drug, all AEs will be reported until 28 days after the final dose of 
study drug.
Instructions for reporting AEs that occur after the AE reporting period are provided in 
Section 5.6.
5.3.2
Eliciting Adverse Event Information
A consistent methodology of non-directive questioning should be adopted for eliciting AE
information at all volunteer evaluation time-points.  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?" 
5.3.3
Assessment of Severity of Adverse Events
The AE severity grading scale for the NCI CTCAE (v5.0) will be used for assessing AE
severity.  Table 5 will be used for assessing severity for AEs that are not specifically 
listed in the NCI CTCAE.

Note:  Based on the most recent version of NCI CTCAE (v5.0), which can be found at:  
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm
a Instrumental activities of daily living refer to preparing meals, shopping for groceries or 
clothes, using the telephone, managing money, etc.
b Examples of self-care activities of daily living include bathing, dressing and undressing, 
feeding oneself, using the toilet, and taking medications, as performed by patients who are 
not bedridden.
c If an event is assessed as a "significant medical event," it must be reported as a serious AE
(see Section 5.4.2 for reporting instructions), per the definition of serious AE in Section 5.2.2.
d Grade 4 and 5 events must be reported as serious AEs (see Section 5.4.2 for reporting 
instructions), per the definition of serious AE in Section 5.2.2.
5.3.4
Assessment of Causality of Adverse Events
Investigators should use their knowledge of the volunteer, 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:

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

Presence of risk factors in the patient 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


Entrectinib—F. Hoffmann-La Roche Ltd
47/Protocol GP41174, Version 2
5.3.5
Procedures for Recording Adverse Events
Investigators should use correct medical terminology/concepts when recording AEs on 
the eCRF.  Avoid colloquialisms and abbreviations.
Only one AE term should be recorded in the event field on the eCRF.
5.3.5.1
Diagnosis versus Signs and Symptoms
A diagnosis (if known) should be recorded on the 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 eCRF.  If a diagnosis is subsequently 
established, all previously reported AEs based on signs and symptoms should be 
nullified and replaced by one 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.
5.3.5.2
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 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 gastrointestinal hemorrhage leads to renal failure, both events should be 
reported separately on the eCRF.

If dizziness leads to a fall and consequent fracture, all three 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 eCRF if it is unclear as to whether the 
events are associated.
5.3.5.3
Persistent or Recurrent Adverse Events
A persistent AE is one that extends continuously, without resolution, between volunteer 
evaluation time-points.  Such events should only be recorded once on the eCRF.  The 
initial severity (intensity or grade) of the event will be recorded at the time the event is 
first reported.  If a persistent AE becomes more severe, the most extreme severity 
should also be recorded on the eCRF.  Details regarding any increases in severity will 
be captured on the eCRF.  If the event becomes serious, it should be reported to the 


Entrectinib—F. Hoffmann-La Roche Ltd
48/Protocol GP41174, Version 2
Sponsor immediately (i.e., no more than 24 hours after learning that the event became 
serious; see Section 5.4.2 for reporting instructions).  The eCRF should be updated by 
changing the event from "non-serious" to "serious," providing the date that the event 
became serious, and completing all data fields related to serious AEs.
A recurrent AE is one that resolves between volunteer evaluation time-points and 
subsequently recurs.  Each recurrence of an AE should be recorded as a separate event 
on the eCRF.
5.3.5.4
Abnormal Laboratory Values
Not every laboratory abnormality qualifies as an AE.  A laboratory test result must 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 
Note:  For oncology trials, certain abnormal values may not qualify as AEs.
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ULN associated with cholestasis), only the 
diagnosis (i.e., cholestasis) should be recorded on the eCRF.
If a clinically significant laboratory abnormality is not a sign of a disease or syndrome, 
the abnormality itself should be recorded on the 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 eCRF (see Section 5.3.5.4 for details on recording 
persistent AEs).


Entrectinib—F. Hoffmann-La Roche Ltd
49/Protocol GP41174, Version 2
5.3.5.5
Abnormal Vital Sign Values
Not every vital sign abnormality qualifies as an AE.  A vital sign result must 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 eCRF.
Observations of the same clinically significant vital sign abnormality from visit to visit 
should only be recorded once on the eCRF (see Section 5.3.5.4 for details on recording 
persistent AEs).
5.3.5.6
Abnormal Liver Function Tests
The finding of an elevated ALT or AST (3baseline value) 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 as an AE the occurrence 
of either of the following:

Treatment-emergent ALT or AST 3baseline value in combination with total 
bilirubin 2ULN (of which 35% is direct bilirubin)

Treatment-emergent ALT or AST 3baseline value 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 eCRF (see Section 5.3.5.2) and reported to 
the Sponsor immediately (i.e., no more than 24 hours after learning of the event), either 
as a serious AE or an AE of special interest (see Section 5.4.2).
5.3.5.7
Deaths
All deaths that occur during the protocol-specified AE reporting period (see 
Section 5.3.1), regardless of relationship to study drug, must be recorded on the eCRF
and immediately reported to the Sponsor (see Section 5.4.2).  This includes death 
attributed to progression of hepatic disease.


Entrectinib—F. Hoffmann-La Roche Ltd
50/Protocol GP41174, Version 2
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 eCRF.  Generally, only one 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 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").
If the death is attributed to progression of liver disease, "hepatic disease progression" 
should be recorded on the eCRF.  
Deaths that occur after the AE reporting period should be reported as described in 
Section 5.6.
5.3.5.8
Pre-existing Medical Conditions
A preexisting medical condition is one that is present at the screening visit for this study.  
Such conditions should be recorded on the eCRF.
A preexisting 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 the eCRF, it is important to convey the concept that the preexisting condition 
has changed by including applicable descriptors (e.g., "more frequent headaches").
5.3.5.9
Worsening of Liver Disease
Medical occurrences or symptoms of deterioration that are anticipated as part of liver 
disease should be recorded as an AE if judged by the Investigator to have unexpectedly 
worsened in severity or frequency or changed in nature at any time during the study.  
When recording an unanticipated worsening of hepatic function on the eCRF, it is 
important to convey the concept that the condition has changed by including applicable 
descriptors (e.g., "accelerated worsening of hepatic function").
5.3.5.10
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 a serious AE (per the definition of 
serious AE in Section 5.2.2), except as outlined below.  
An event that leads to hospitalization under the following circumstances should not be 
reported as an AE or a serious AE:

Hospitalization for respite care


Entrectinib—F. Hoffmann-La Roche Ltd
51/Protocol GP41174, Version 2

Hospitalization for a preexisting condition, provided that all of the following criteria 
are met:
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
The patient has not experienced an AE
An event that leads to hospitalization under the following circumstances is not 
considered to be a serious AE, but should be reported as an AE instead:

Hospitalization that was necessary because of patient requirement for outpatient 
care outside of normal outpatient clinic operating hours
5.4
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; 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 after 
learning of the event, regardless of relationship to study drug:

Serious AEs (defined in Section 5.2.2; see Section 5.4.2 for details on reporting 
requirements)

Adverse events of special interest (defined in Section 5.2.3; see Section 5.4.2 for 
details on reporting requirements)

Pregnancies (see Section 5.4.3 for details on reporting requirements)

Accidental overdoses or medication errors (see Section 5.4.4 for details on reporting 
requirements)
The Investigator must report new significant follow-up information for these events to the 
Sponsor immediately (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 serious AEs to the 
local health authority and IRB/EC.

Reporting Requirements for Serious Adverse Events and 
Adverse Events of Special Interest
5.4.2.1
Events That Occur prior to Study Drug Initiation
After informed consent has been obtained but prior to initiation of study drug, only 
serious AEs caused by a protocol-mandated intervention should be reported.  The paper 
Clinical Trial Serious Adverse Event/Adverse Event of Special Interest Reporting Form 
provided to Investigators should be completed and submitted to the Sponsor or its 
designee immediately (i.e., no more than 24 hours after learning of the event), either by 
faxing or by scanning and emailing the form using the fax number or email address 
provided to Investigators.
5.4.2.2
Events That Occur after Study Drug Initiation
After initiation of study drug, serious AEs and AEs of special interest will be reported 
until 28 days after the dose of study drug.  Investigators should record all case details 
that can be gathered immediately (i.e., within 24 hours after learning of the event) on the 
eCRF and submit the report via the electronic data capture (EDC) system.  An 
electronic report will be generated and sent to Roche Safety Risk Management.
In the event that the EDC system is unavailable, the paper Clinical Trial Serious Adverse 
Event/Adverse Event of Special Interest Reporting Form provided to Investigators should 
be completed and submitted to the Sponsor or its designee immediately (i.e., no more 
than 24 hours after learning of the event), either by faxing or by scanning and emailing 
the form using the fax number or email address provided to Investigators.  Once the 
EDC system is available, all information will need to be entered and submitted via the 
EDC system.  
Instructions for reporting serious AEs that occur 28 days after the dose of study 
treatment are provided in Section 5.6.
5.4.3
Reporting Requirements for Pregnancies
5.4.3.1
Pregnancies in Female Patients
Female volunteers of childbearing potential will be instructed to immediately inform the 
Investigator if they become pregnant during the study or within 28 days after the dose of 
study drug.  A paper Clinical Trial Pregnancy Reporting Form should be completed and 
submitted to the Sponsor or its designee immediately (i.e., no more than 24 hours after 
learning of the pregnancy), either by faxing or by scanning and emailing the form using 
the fax number or email address provided to Investigators.  Pregnancy should not be 
recorded on the eCRF.  The Investigator should counsel the volunteer, discussing the 


Entrectinib—F. Hoffmann-La Roche Ltd
53/Protocol GP41174, Version 2
risks of the pregnancy and the possible effects on the fetus.  Monitoring of the volunteer
should continue until conclusion of the pregnancy.  Any serious AEs 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 
eCRF.  In addition, the Investigator will submit a Clinical Trial Pregnancy Reporting Form 
when updated information on the course and outcome of the pregnancy becomes 
available.  
5.4.3.2
Pregnancies in Female Partners of Male Volunteers
Male volunteers will be instructed through the Informed Consent Form to immediately 
inform the Investigator if their partner becomes pregnant during the study or within 28 
days after the dose of study drug.  A paper Clinical Trial Pregnancy Reporting Form 
should be completed and submitted to the Sponsor or its designee immediately (i.e., no 
more than 24 hours after learning of the pregnancy), either by faxing or by scanning and 
emailing the form using the fax number or email address provided to Investigators.  
Attempts should be made to collect and report details of the course and outcome of any 
pregnancy in the partner of a male volunteer 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 volunteer
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.
5.4.3.3
Abortions
Any abortion should be classified as a serious AE (as the Sponsor considers abortions 
to be medically significant), recorded on the eCRF, and reported to the Sponsor 
immediately (i.e., no more than 24 hours after learning of the event; see Section 5.4.2).  
5.4.3.4
Congenital Anomalies/Birth Defects
Any congenital anomaly/birth defect in a child born to a female volunteer exposed to 
study drug or the female partner of a male volunteer exposed to study drug should be 
classified as a serious AE, recorded on the eCRF, and reported to the Sponsor 
immediately (i.e., no more than 24 hours after learning of the event; see Section 5.4.2).
5.4.4
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


Entrectinib—F. Hoffmann-La Roche Ltd
54/Protocol GP41174, Version 2

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 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 5.4.2).  
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 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 two eCRF pages, one to report the accidental overdose and one to report 
the headache.
5.5
FOLLOW-UP OF PATIENTS AFTER ADVERSE EVENTS
5.5.1
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 volunteer is lost to follow-up, 
or the volunteer withdraws consent.  Every effort should be made to follow all serious AEs 


Entrectinib—F. Hoffmann-La Roche Ltd
55/Protocol GP41174, Version 2
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 eCRF
and in the volunteer's medical record to facilitate source data verification.
All pregnancies reported during the study should be followed until pregnancy outcome.
5.5.2
Sponsor Follow-Up
For serious AEs, AEs of special interest, 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.
5.6
ADVERSE EVENTS THAT OCCUR AFTER THE ADVERSE 
EVENT REPORTING PERIOD
The Sponsor should be notified if the Investigator becomes aware of any serious AE 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 use of the eCRF.  However, if the EDC system is not 
available, the Investigator should report these events directly to the Sponsor or its 
designee, either by faxing or by scanning and emailing the paper Clinical Trial Serious 
Adverse Event/Adverse Event of Special Interest Reporting Form using the fax number 
or email address provided to Investigators.
5.7
EXPEDITED REPORTING TO HEALTH AUTHORITIES, 
INVESTIGATORS, INSTITUTIONAL REVIEW BOARDS, AND 
ETHICS COMMITTEES
The Sponsor will promptly evaluate all serious AEs and AEs of special interest 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 Investigator's Brochure
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.

STATISTICAL CONSIDERATIONS AND ANALYSIS PLAN
6.1
DETERMINATION OF SAMPLE SIZE
It is planned that approximately 24 volunteers will be enrolled, with a target of six in each 
hepatic function group. The actual number enrolled will be determined by the Sponsor 
during the study from review of emerging data to ensure that at least six individuals are 
recruited in each hepatic function group for both classification systems, i.e. additional 
volunteers will be recruited if differences between the two categorization systems mean 
that there are fewer than six evaluable individuals in any hepatic function analysis group. 
Volunteers who withdraw from the study before Day 7 may also be replaced to ensure 
that at least six volunteers in each group have evaluable pharmacokinetic data.
No formal sample size calculations were performed. Six volunteers per group is 
consistent with recommendations in US and European regulatory guidelines [3, 4]. 
Based on the observed variability in entrectinib exposure parameters in previous clinical 
studies (e.g. AUCinf CV% 9-34% from F06 capsules in healthy volunteers under fed 
conditions) six volunteers per group is considered appropriate to estimate the magnitude 
of the effect of hepatic impairment on entrectinib pharmacokinetic parameters.
6.2
SUMMARIES OF CONDUCT OF STUDY
The number of volunteers who enroll, discontinue, or complete the study will be 
summarized.  Reasons for premature study withdrawal will be listed and summarized.  
Enrollment and major protocol deviations will be listed and evaluated for their potential 
effects on the interpretation of study results.
6.3
SUMMARIES OF DEMOGRAPHIC AND BASELINE 
CHARACTERISTICS
Demographic and baseline characteristics (including age and sex) will be summarized 
using means, standard deviations, medians, and ranges for continuous variables and 
proportions for categorical variables, as appropriate. Summaries will be presented 
overall and by hepatic function group.
6.4
SAFETY ANALYSES
The safety analysis population will consist of all volunteers who received one dose of 
study drug, with volunteers grouped according to hepatic function category.
All verbatim AE terms will be mapped to Medical Dictionary for Regulatory Activities 
(MedDRA) thesaurus terms, and AE severity will be graded according to NCI CTCAE 
v5.0.
Safety will be assessed by a review of AEs, vital signs, clinical laboratory assessments, 
and ECGs. Adverse events will be summarized by hepatic function group. Duplicate
summaries will be presented for the Child Pugh and NCI-ODWG systems for classifying 
hepatic function. Clinical laboratory assessments, vital signs (including oral temperature, 


Entrectinib—F. Hoffmann-La Roche Ltd
57/Protocol GP41174, Version 2
respiratory rate, and supine blood pressure and pulse rate), and ECGs will be listed by 
volunteer and scheduled time. Changes from baseline and the incidence of out-of-
reference range values will be derived as appropriate.
6.5
PHARMACOKINETIC ANALYSES
Plasma concentrations of entrectinib and its active metabolite M5, and derived plasma 
pharmacokinetic parameters, will be listed and summarized by group using descriptive 
statistics. Individual and mean concentration versus time profiles will be plotted. 
Duplicate summaries will be presented for groups categorized according to the Child 
Pugh and NCI-ODWG system for classifying hepatic function. In effect there may be 
eight analysis groups (i.e. Normal Child-Pugh, Normal NCI-ODWG, Mild Child-Pugh, 
Mild NCI-ODWG, Moderate Child-Pugh, Moderate NCI-ODWG, Severe Child-Pugh, and 
Severe NCI-ODWG).
The following pharmacokinetic parameters will be derived for entrectinib and M5 using 
standard non-compartmental methods: 

Cmax:  Maximum observed plasma concentration

AUClast: Area under the plasma concentration-time curve from time 0 to the last 
measurable concentration.

AUCinf:  Area under the plasma concentration-time curve from time 0 extrapolated 
to infinity.

Tmax:  Time of Maximum observed plasma concentration

λz:  Apparent terminal elimination rate constant

t1/2:  Apparent terminal elimination half-life

M:P ratio:  Molecular weight-adjusted metabolite to parent ratio based on AUCinf

CL/F:  Apparent oral clearance (entrectinib only)

V/F:  Apparent volume of distribution (entrectinib only) 

fu:  Fraction of drug unbound in plasma
The fractions of entrectinib and M5 unbound in plasma (fu) will be determined by ex vivo 
protein binding assay and used to calculate exposure parameters adjusted for protein 
binding (i.e., unbound Cmax, unbound AUCinf).
An analysis of variance (ANOVA) will be used to estimate the effect of hepatic 
impairment on log-transformed total and unbound entrectinib and M5 exposure
parameters and will include the factor hepatic impairment (i.e. mild, moderate and 
severe, and none). Estimates of geometric mean ratios on the original scale, together 
with the corresponding 90% confidence intervals (CIs), will be derived for the 
comparisons between each hepatic impairment group and the control group with normal 
hepatic function. Duplicate analyses will be performed for groups based on Child-Pugh 
and NCI-ODWG classifications.


Entrectinib—F. Hoffmann-La Roche Ltd
58/Protocol GP41174, Version 2
The relationship between entrectinib pharmacokinetic parameters (e.g. Cmax and AUCinf) 
and measures of hepatic function (e.g., Child-Pugh scores, albumin, bilirubin, or AST 
concentrations, prothrombin time etc.) will be explored using linear or non-linear models 
or regression analyses, as appropriate. 
6.6
INTERIM ANALYSIS
Pharmacokinetic and safety data from at least three volunteers with mild hepatic
impairment and three volunteers with moderate hepatic impairment (Child-Pugh 
categorization system) will be reviewed before volunteers with severely impaired hepatic 
function are enrolled. Data will be listed and summarized as appropriate but there will be 
no formal statistical analysis. Recruitment of volunteers with severely impaired hepatic 
function will only proceed if there is agreement between the Sponsor and the 
Investigator that data from this group are necessary to fulfill the objectives of the study
and that dosing is not anticipated to present an unacceptable risk to those individuals.
7.
DATA COLLECTION AND MANAGEMENT
7.1
DATA QUALITY ASSURANCE
A contract research organization (CRO) will be responsible for data management of this 
study, including quality checking of the data.  Data entered manually will be collected via 
EDC through use of eCRFs.  Sites will be responsible for data entry into the EDC 
system.  In the event of discrepant data, the CRO will request data clarification from the 
sites, which the sites will resolve electronically in the EDC system.
The CRO will produce a Data Quality Plan that describes the quality checking to be 
performed on the data. Laboratory data will be sent directly to the CRO, using the 
standard procedures to handle and process transfer of these data.
The Sponsor will perform oversight of the data management of this study.  Data will be 
periodically transferred from the CRO to the Sponsor using pre-agreed procedures to 
handle and process the transfer of these data.
eCRFs and correction documentation will be maintained in the EDC system's audit trail.  
System backups for data stored at the CRO and records retention for the study data will 
be consistent with the CRO's standard procedures.
7.2
ELECTRONIC CASE REPORT FORMS 
eCRFs are to be completed through use of an EDC system.  Sites will receive training 
and have access to a manual for appropriate eCRF completion.  eCRFs will be 
submitted electronically to the CRO and should be handled in accordance with the 
CRO's standard procedures.
All eCRFs should be completed by designated, trained site staff.  eCRFs should be 
reviewed and electronically signed and dated by the Investigator or a designee.


Entrectinib—F. Hoffmann-La Roche Ltd
59/Protocol GP41174, Version 2
At the end of the study, the Investigator will receive volunteer data for his or her site in a 
readable format that must be kept with the study records.  Acknowledgement of receipt 
of the data is required.
7.3
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 volunteer 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, patient-reported outcomes, 
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, 
patient files, and records kept at pharmacies, laboratories, and medico-technical 
departments involved in a clinical trial.
Before study initiation, the types of source documents that are to be generated will be 
clearly defined in the Trial Monitoring Plan.  This includes any protocol data to be 
entered directly into the eCRFs (i.e., no prior written or electronic record of the data) and 
considered source data.
Source documents that are required to verify the validity and completeness of data 
entered into the eCRFs must not be obliterated or destroyed and must be retained per 
the policy for retention of records described in Section 7.5.
To facilitate source data verification and review, the Investigators and institutions 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.
7.4
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 health 
authority requirements pertaining to computerized systems used in clinical research.  An 
acceptable computerized data collection system allows preservation of the original entry 
of data.  If original data are modified, the system should maintain a viewable audit trail 
that shows the original data as well as the reason for the change, name of the person 
making the change, and date of the change.


Entrectinib—F. Hoffmann-La Roche Ltd
60/Protocol GP41174, Version 2
7.5
RETENTION OF RECORDS
Records and documents pertaining to the conduct of this study and the distribution of 
IMP, including eCRFs, electronic or paper PRO data (if applicable), Informed Consent 
Forms, laboratory test results, and medication inventory records, must be retained by the 
Principal Investigator for at least 15 years after completion or discontinuation of the 
study or for the length of time required by relevant national or local health authorities, 
whichever is longer.  After that period of time, the documents may be destroyed, subject 
to local regulations.  
No records may 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.
8.
ETHICAL CONSIDERATIONS
8.1
COMPLIANCE WITH LAWS AND REGULATIONS
This study will be conducted in full conformance with the ICH E6 guideline for Good 
Clinical Practice and the principles of the Declaration of Helsinki, or the laws and 
regulations of the country in which the research is conducted, whichever affords the 
greater protection to the individual.  The study will comply with the requirements of the 
ICH E2A guideline (Clinical Safety Data Management:  Definitions and Standards for 
Expedited Reporting).  Studies conducted in the United States or under a U.S. 
Investigational New Drug (IND) Application will comply with U.S. FDA regulations and 
applicable local, state, and federal laws.  Studies conducted in the European Union or 
European Economic Area will comply with the E.U. Clinical Trial Directive (2001/20/EC).
8.2
INFORMED CONSENT
The Sponsor's sample Informed Consent Form (and ancillary sample Informed Consent 
Forms such as a Child's Informed Assent Form or Mobile Nursing Informed Consent 
Form, if applicable) will be provided to each site.  If applicable, it will be provided in a 
certified translation of the local language.  The Sponsor or its designee must review and 
approve any proposed deviations from the Sponsor's sample Informed Consent Forms 
or any alternate consent forms proposed by the site (collectively, the "Consent Forms") 
before IRB/EC submission.  The final IRB/ECapproved Consent Forms must be 
provided to the Sponsor for health authority submission purposes according to local 
requirements.
If applicable, the Informed Consent Form will contain separate sections for any optional 
procedures.  The Investigator or authorized designee will explain to each volunteer the 
objectives, methods, and potential risks associated with each optional procedure.  
Patients will be told that they are free to refuse to participate and may withdraw their 
consent at any time for any reason.  A separate, specific signature will be required to 
document a volunteer's agreement to participate in optional procedures.  Patients who 
decline to participate will not provide a separate signature.


Entrectinib—F. Hoffmann-La Roche Ltd
61/Protocol GP41174, Version 2
The Consent Forms must be signed and dated by the volunteer or the volunteer's legally 
authorized representative before his or her participation in the study.  The case history or 
clinical records for each volunteer shall document the informed consent process and that 
written informed consent was obtained prior to participation in the study.
The Consent Forms should be revised whenever there are changes to study procedures 
or when new information becomes available that may affect the willingness of the 
volunteer to participate.  The final revised IRB/EC-approved Consent Forms must be 
provided to the Sponsor for health authority submission purposes.
Patients must be re-consented to the most current version of the Consent Forms (or to a 
significant new information/findings addendum in accordance with applicable laws and 
IRB/EC policy) during their participation in the study.  For any updated or revised 
Consent Forms, the case history or clinical records for each volunteer shall document 
the informed consent process and that written informed consent was obtained using the 
updated/revised Consent Forms for continued participation in the study.
A copy of each signed Consent Form must be provided to the volunteer or the 
volunteer's legally authorized representative.  All signed and dated Consent Forms must 
remain in each volunteer's study file or in the site file and must be available for 
verification by study monitors at any time.
For sites in the United States, each Consent Form may also include volunteer
authorization to allow use and disclosure of personal health information in compliance 
with the U.S. Health Insurance Portability and Accountability Act (HIPAA) of 1996.  If the 
site utilizes a separate Authorization Form for volunteer authorization for use and 
disclosure of personal health information under the HIPAA regulations, the review, 
approval, and other processes outlined above apply except that IRB review and approval 
may not be required per study site policies.
8.3
INSTITUTIONAL REVIEW BOARD OR ETHICS COMMITTEE
This protocol, the Informed Consent Forms, any information to be given to the volunteer, 
and relevant supporting information must be submitted to the IRB/EC by the Principal 
Investigator and reviewed and approved by the IRB/EC before the study is initiated.  
In addition, any volunteer recruitment materials must be approved by the IRB/EC. 
The Principal Investigator is responsible for providing written summaries of the status of 
the study to the IRB/EC annually or more frequently in accordance with the 
requirements, policies, and procedures established by the IRB/EC.  Investigators are 
also responsible for promptly informing the IRB/EC of any protocol amendments (see 
Section 9.6).
In addition to the requirements for reporting all AEs to the Sponsor, Investigators must 
comply with requirements for reporting serious AEs to the local health authority and 


Entrectinib—F. Hoffmann-La Roche Ltd
62/Protocol GP41174, Version 2
IRB/EC.  Investigators may receive written IND safety reports or other 
safetyrelated- communications from the Sponsor.  Investigators are responsible for 
ensuring that such reports are reviewed and processed in accordance with health 
authority requirements and the policies and procedures established by their IRB/EC, and 
archived in the site's study file. 
8.4
CONFIDENTIALITY
The Sponsor maintains confidentiality standards by coding each volunteer enrolled in the 
study through assignment of a unique volunteer identification number.  This means that 
volunteer names are not included in data sets that are transmitted to any Sponsor 
location.
Patient medical information obtained by this study is confidential and may be disclosed 
to third parties only as permitted by the Informed Consent Form (or separate 
authorization for use and disclosure of personal health information) signed by the 
volunteer, unless permitted or required by law.
Medical information may be given to a volunteer's personal physician or other 
appropriate medical personnel responsible for the volunteer's welfare, for treatment 
purposes.
Given the complexity and exploratory nature of exploratory biomarker analyses, data 
derived from these analyses will generally not be provided to study Investigators or 
volunteers 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 
(see Section 9.5).
Data generated by this study must be available for inspection upon request by 
representatives of national and local health authorities, Sponsor monitors, 
representatives, and collaborators, and the IRB/EC for each study site, as 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 clinical study reports and other summary reports will be provided upon 
request.
8.5
FINANCIAL DISCLOSURE
Investigators will provide the Sponsor with sufficient, accurate financial information in 
accordance with local regulations to allow the Sponsor to submit complete and accurate 
financial certification or disclosure statements to the appropriate health authorities.  
Investigators are responsible for providing information on financial interests during the 


Entrectinib—F. Hoffmann-La Roche Ltd
63/Protocol GP41174, Version 2
course of the study and for 1 year after completion of the study (see definition of end of 
study in Section 3.2).
9.
STUDY DOCUMENTATION, MONITORING, AND 
ADMINISTRATION
9.1
STUDY DOCUMENTATION
The Investigator must maintain adequate and accurate records to enable the conduct of 
the study to be fully documented, including, but not limited to, the protocol, protocol 
amendments, Informed Consent Forms, and documentation of IRB/EC and 
governmental approval.  In addition, at the end of the study, the Investigator will receive 
the volunteer data, including an audit trail containing a complete record of all changes to 
data.
9.2
PROTOCOL DEVIATIONS
The Investigator should document and explain any protocol deviations. The Investigator
should promptly report any deviations that might have an impact on volunteer safety and 
data integrity to the Sponsor and to the IRB/EC in accordance with established IRB/EC 
policies and procedures.  The Sponsor will review all protocol deviations and assess 
whether any represent a serious breach of Good Clinical Practice guidelines and require 
reporting to health authorities.  As per the Sponsor's standard operating procedures, 
prospective requests to deviate from the protocol, including requests to waive protocol 
eligibility criteria, are not allowed.
9.3
SITE INSPECTIONS
Site visits will be conducted by the Sponsor or an authorized representative for 
inspection of study data, volunteers' medical records, and eCRFs.  The Investigator will 
permit national and local health authorities; Sponsor monitors, representatives, and 
collaborators; and the IRBs/ECs to inspect facilities and records relevant to this study.
9.4
ADMINISTRATIVE STRUCTURE
This trial will be sponsored by F. Hoffmann-La Roche Ltd and managed by a CRO.  The 
Sponsor will provide medical monitoring and will be responsible for expedited reporting 
of new safety findings but other activities will be delegated to the CRO.
Central facilities will be used for certain study assessments throughout the study (e.g., 
bioanalysis).  Accredited local laboratories may be used for routine safety monitoring; 
local laboratory ranges will be collected.
9.5
DISSEMINATION OF DATA AND PROTECTION OF TRADE 
SECRETS
Regardless of the outcome of a trial, the Sponsor is dedicated to openly providing 
information on the trial to healthcare professionals and to the public, at scientific 
congresses, in clinical trial registries of the U.S. National Institutes of Health and the 


Entrectinib—F. Hoffmann-La Roche Ltd
64/Protocol GP41174, Version 2
European Medicines Agency, and in peer-reviewed journals. The Sponsor will comply 
with all requirements for publication of study results.  Study data may be shared with 
others who are not participating in this study, and redacted clinical study reports and 
other summary reports will be provided upon request (see Section 8.4 for more details).  
For more information, refer to the Roche Global Policy on Sharing of Clinical Trials Data 
at the following website:
www.roche.com/roche_global_policy_on_sharing_of_clinical_study_information.pdf
The results of this study may be published or presented at scientific congresses.  For all 
clinical trials in patients involving an IMP for which a marketing authorization application 
has been filed or approved in any country, the Sponsor aims to submit a journal 
manuscript reporting primary clinical trial results within 6 months after the availability of 
the respective Clinical Study Report.  In addition, for all clinical trials in patients involving 
an IMP for which a marketing authorization application has been filed or approved in any 
country, the Sponsor aims to publish results from analyses of additional endpoints and 
exploratory data that are clinically meaningful and statistically sound.
The Investigator must agree to submit all manuscripts or abstracts to the Sponsor prior 
to submission for publication or presentation.  This allows the Sponsor to protect 
proprietary information and to provide comments based on information from other 
studies that may not yet be available to the Investigator.
In accordance with standard editorial and ethical practice, the Sponsor will generally 
support publication of multicenter trials only in their entirety and not as individual center 
data.  In this case, a coordinating Investigator will be designated by mutual agreement.
Authorship will be determined by mutual agreement and in line with International 
Committee of Medical Journal Editors authorship requirements.  Any formal publication 
of the study in which contribution of Sponsor personnel exceeded that of conventional 
monitoring will be considered as a joint publication by the Investigator and the 
appropriate Sponsor personnel.
Any inventions and resulting patents, improvements, and/or know-how originating from 
the use of data from this study will become and remain the exclusive and unburdened 
property of the Sponsor, except where agreed otherwise.
9.6
PROTOCOL AMENDMENTS
Any protocol amendments will be prepared by the Sponsor.  Protocol amendments will 
be submitted to the IRB/EC and to regulatory authorities in accordance with local 
regulatory requirements.
Approval must be obtained from the IRB/EC and regulatory authorities (as locally 
required) before implementation of any changes, except for changes necessary to 


Entrectinib—F. Hoffmann-La Roche Ltd
65/Protocol GP41174, Version 2
eliminate an immediate hazard to volunteers or changes that involve logistical or 
administrative aspects only (e.g., change in Medical Monitor or contact information).
