Protocol Amendments
Amendments
Date of Issue
Summary of Major Changes
Revised Protocol 1
08-JUL-2015
- Update the dose of DTIC per China label requirement.
- Other changes per program level standards and model document.
Revised Protocol 2
23-DEC-2015
- Remove the use of a Data Monitoring Committee (DMC since:
1) This is an open-label study;
2) This is a single country study (China) and not a MRCT (Multi 
Regional Clinical Trial) and therefore an independent DMC is not 
required as per the Chinese regulation.
- Further clarification with regards to:
1) The infusion pump used for the administration of ipilimumab;
2) The T&E schedule (Endocrine assessments and collection of 
PK/ADA)
Revised Protocol 3
20-DEC-2018
-Change in primary objective and primary endpoint to 2-year OS rate 
from OS
-Change in allowable minimum scan time from baseline for 
determination of stable disease from 12 weeks to 8 weeks per RECIST 
v1.1 guidelines

ENDPOINTS
4.1
Primary Endpoint
4.1.1
Two-Year Survival Rate
Two-year survival rate is defined as the probability that a subject is alive at 2 years following the 
randomization date and will be estimated via the Kaplan-Meier (KM) method.
4.2
Secondary Endpoints
Secondary response-based endpoints of PFS, DCR, DoR, DoSD, and BORR will be captured using 
the RECIST v1.1 criteria.
4.2.1
One-Year Survival Rate 
Survival rate at 1 year is defined as the probability that a subject is alive at 1 year following the
randomization date and will be estimated via the Kaplan-Meier (KM) method.
4.2.2
Overall Survival
OS is defined for each subject as the time between randomization date and the date of death (of 
any cause). If a subject has not died, the subject will be censored at the time of last contact (last 
known alive date).
A modified variable will be examined for the purposes of sensitivity analysis:
•
OS accounting for subsequent PD-1/PD-L1 therapy will be defined through addition of the 
following restriction to the primary definition: subjects who receive subsequent PD-1/PD-L1 
cancer therapy will be censored at the start date of subsequent PD-1/PD-L1 therapy.
4.2.3
Progression Free Survival
PFS is defined for each subject as the time between randomization date and the date of progression 
or death, whichever occurs first. The date of progression will be taken from the investigator 
assessment of progression on the CRF. A subject who dies without reported prior progression will 
be considered to have progressed on the date of death if no subsequent therapy prior to death date. 
For those who remain alive and have not progressed, PFS will be censored on the date of last 
evaluable tumor assessment (TA) prior to subsequent therapy. For those who remain alive and 
have no recorded evaluable TAs post baseline, PFS will be censored on the date of randomization.

For subjects without baseline tumor assessment, PFS will also be censored on the date of 
randomizaion.
Modified variables will be examined for the purposes of sensitivity analysis:

PFS accounting for early TAs in DTIC group is defined in the same manner as PFS, except 
that for subjects randomized to DTIC with radiographic, photographic or clinical evidence of 
progression before Week 12, subjects will be considered to have PD at Week 12.
4.2.4
Disease Control Rate
Primary disease control rate (DCR) definition is defined as the number of subjects in the arm with 
Best Overall Response (BOR) of complete response (CR), partial response (PR), or stable disease 
(SD), divided by the total number of randomized subjects in the arm.
Per protocol DCR definition is defined as the number of response evaluable subjects in the arm
with BOR of complete response (CR), partial response (PR), or stable disease (SD), divided by the 
total number of response evalubale subjects in the arm.
4.2.5
Best Overall Response Rate
Primary BORR definition is defined as the number of subjects in the arm with a BOR of CR or 
PR, divided by the total number of randomized subjects in the arm.
Per protocol BORR definition is defined as the number of response evaluable subjects in the arm 
with a BOR of CR or PR, divided by the total number of response evaluable subjects in the arm.
4.2.6
Duration of Response
Primary duration of response (DoR) definition for the randomized subjects whose BOR is CR or 
PR is defined as the time between the date of response of CR or PR (whichever occurs first) and 
the first date of progressive disease (PD) or the date of death (whichever occurs first). 
Per protocol DoR definition for the response evaluable subjects whose BOR is CR or PR is defined
as the time between the date of response of CR or PR (whichever occurs first) and the first date of 
progressive disease (PD) or the date of death (whichever occurs first). 
For both definitions, for subjects who underwent tumor resection following response but prior to 
disease progression, DoR will be censored on the date of the last evaluable TA prior to resection. 
For subjects who remain alive and have not progressed following response, DoR will be censored 
on the date of last evaluable TA prior to subsequent therapy.
4.2.7
Duration of Stable Disease
Primary duration of stable disease (DoSD) definition for the randomized subjects whose BOR is 
SD is defined as the time between the randomization date and the first date of PD or the date of 
death (whichever occurs first). 
Per protocol DoSD definition for the response evaluable subjects whose BOR is SD is defined as 
the time between the randomization date and the first date of PD or the date of death (whichever 
occurs first).

SAMPLE SIZE AND POWER
Approximately 180 Chinese subjects will be randomized to ipilimumab and DTIC at a 2:1 ratio
and followed  at least 2 years after randomization to ensure 80% power through simulation using 
a  chi-squared test with a Type I error rate of 0.20 to reject the null hypothesis of no difference in 
2-year survival rate between treatment groups, assuming a HR [ipilimumab vs DTIC] of 0.67. 
Under an exponential distribution, this hazard ratio (HR) would correspond to an 12 month median 
OS for the ipilimumab arm with an 8 month median OS in the DTIC arm8(or equivalently 25% 
and 12.5% in the ipilimumab and DTIC arm). The accrual duration is approximately 18 months, 
assuming a monthly rate of 10 subjects per month. The  primary analysis will be performed about 
42 months after the first subject is randomized.

STUDY PERIODS, TREATMENT REGIMENS AND POPULATIONS FOR 
ANALYSES
6.1
Study Periods

Baseline period:

Baseline evaluations or events will be defined as evaluations or events that occur before
the date and time of the first dose of study treatment. Evaluations on the same date and
time of the first dose of study treatment will be considered as baseline evaluations.

In cases where the time (onset time of event or evaluation time and dosing time) is missing 
or not collected, the following definitions will apply:
Pre-treatment AEs will be defined as AEs with an onset date prior to but not including 
the day of the first dose of study treatment.
Baseline evaluations (laboratory tests, etc.) will be defined as evaluations with a date 
on or prior to the day of first dose of study treatment.

If there are multiple valid assessments, the assessment that is closest to day (and time if collected) 
of the first dose of study treatment will be used as the baseline in the analyses. If multiple 
assessments are collected on the same date (and time, if collected), the assessment with the latest 
database entry date (and time, if collected) will be considered as baseline, unless mentioned 
otherwise.

Post baseline period:

On-treatment AEs will be defined as AEs with an onset date and time on or after the date
and time of the first dose of study treatment (or with an onset date on or after the day of
first dose of study treatment if time is not collected or is missing). For subjects who are off 
study treatment, AEs will be included if event occurred within a safety window of 90 days
after the last dose of study treatment. No ‘subtracting rule’ will be applied when an AE 
occurs both pre-treatment and posttreatment with the same preferred term and grade.

On-treatment evaluations (laboratory tests, etc.) will be defined as evaluations taken after 
the day (and time, if collected and not missing) of first dose of study treatment. For subjects 
who are off study treatment, evaluations should be within a safety window of 90 days after 
the last dose of study treatment.
6.2
Treatment Regimens
The treatment group “as randomized” will be retrieved from the IVRS system

Arm A: ipilimumab

Arm B: DTIC
The treatment group “as treated” will be the same as the arm randomized by IVRS. However, if 
a subject received the incorrect drug for the entire period of treatment, the subject’s treatment 
group will be defined as the incorrect drug the subject actually received.
6.3
Populations for Analyses
The statistical analyses in this study will be defined with respect to the following data sets.
All Enrolled Subjects: All subjects who signed an informed consent form and were registered 
into the IVRS. Subject disposition will be based on all enrolled subjects.
All Randomized Subjects: All enrolled subjects who were randomized to a treatment arm 
(ipilimumab or DTIC). Unless otherwise indicated, analyses of most of study population and 
efficacy endpoints will be based on all randomized subjects and will be performed using the 
treatment group as randomized (i.e. on an intent-to-treat basis). Analyses of QoL will also be based 
on the all randomized subjects population: subjects with both baseline and on-study measurements 
will contribute to the analyses of change at on-study time-points.
Response Evaluable Subjects: All randomized subjects who have measurable disease (i.e., at 
least one measurable lesion) at baseline.
All Treated Subjects: All subjects who received at least one dose of treatment with ipilimumab
or DTIC. Unless otherwise specified, analyses of safety and extent of exposure will be based on

STATISTICAL ANALYSES
7.1
General Methods
No interim analyses are planned for this study. The final analysis will be performed when a 
minimum of 2 year follow-up is reached by all randomized subjects.
Unless otherwise noted, the bulleted titles in the following subsections describe tabulations of
discrete variables, by the frequency and proportion of subjects falling into each category, grouped 
by treatment (with total). Percentages given in these tables will be rounded to the first decimal and, 
therefore, may not always sum to 100%. Percentages less than 0.1 will be indicated as ‘< 0.1’.
Continuous variables will be summarized by treatment group (with total) using the mean, standard 
deviation, median, minimum and maximum values. Subject listings will be produced to 
accompany the tabulations. Time-to-event variables (e.g. time-to resolution) will be analyzed 
using the Kaplan-Meier technique. When specified, the median will be reported along with 80% 
CI using Brookmeyer and Crowley method9 (using log-log transformation for constructing the 
confidence intervals). The conventions to be used for imputing partial dates for analyses requiring 
dates are described in Section 8.
Frequency tables of subject characteristics and subset analyses of efficacy endpoints (including
those by M-substage and BRAF mutation status) will be based on the assessment recorded on the
baseline CRF. However, stratified analyses will be based on the variables used by the IVRS to
randomize the subject.
Assessments taken during re-induction and subsequent progression follow-up phase will not 
contribute to derived endpoints, such as BOR or PFS, since these assessments are necessarily 
following an initial progression. However exploratory version of these endpoints corresponding to 
the administration of re-induction therapy may be performed (if there are sufficient data) - details
will be provided in the DPP.
All statistical analyses will be carried out using SAS software (SAS Institute, Cary, North Carolina, 
USA), unless otherwise noted.

Protocol Deviations
Each subject’s data will be examined for deviation from protocol criteria (including violation of
eligibility criteria and on-study deviations). ‘Significant’ deviations include those that could have
an impact on the primary results of the study, those of ethical concern and those which pose a 
safety risk to the subject. The ‘Relevant’ deviations are those ‘Significant” deviations that 
significantly affect interpretability of the study results. (Subjects who never received their

Efficacy
All hypothesis testing will be two-sided and will be based upon a significance level of 0.20.
No type I error rate multiplicity adjustment will be made for secondary endpoint testing. P-values
associated with the comparisons of OS, DCR and PFS will be purely descriptive in nature. All
efficacy analyses will be based on all randomized subjects, as randomized, unless indicated.

Survival Rates at Specified Time Points
Yearly survival rates will be calculated for each treatment group using the KM product-limit 
method, along with their corresponding log-log transformed 80% CIs10.
Two-year survival rate is the primary endpoint. The survival rate at 2 years will be compared 
between treatment group using a chi-square test stratified by M substage (M1a+M1b versus M1c) 
and BRAF mutation status (yes vs no), as recorded in the IVRS. The stratified chi-square test is 
defined by the following formula:

CONVENTIONS
Unless otherwise noted, the following conventions should be understood to apply. Further 
conventions may be detailed in the Data Presentation Plan.

Day
Assessment times will be calculated relative to the first date of study medication, i.e. Day 1.
Events will be considered as occurring within X days (e.g. deaths within 30 days, deaths and AEs 
within 90 days) of last dose of study medication if [event date] – [last dosing date] X. 
The following factors will convert days to months or years: 1 month = 30.4375 days, 
1 year = 365.25 days.
Conventions for Partial/Missing Dates
Unless specified otherwise the following conventions will be used for imputing partial dates:

If only the day of the month is missing, the 15th of the month will be used to replace the 
missing day.

If both the day and the month are missing, "July 1" will be used to replace the missing 
information.

If a date is completely missing, it will be considered as missing.
For date of death:

If only the day of the month is missing, in principle the 1st of the month will be used to replace 
the missing day - but the imputed day of death will still be compared to the last known alive 
date (date of censoring for survival), and may be adjusted to ensure consistency.

If both the day and the month are missing, in principle "Jan 1" will be used to replace the 
missing information - but the imputed day of death will still be compared to the last known 
alive date (date of censoring for survival), and may be adjusted to ensure consistency.

If date is missing, death date will be imputed as the last known alive date + 1 day.
For date of progression:

If only the day of the month is missing, the 1st of the month will be used to replace the missing 
day(*).


If the day and month are missing or a date is completely missing, it will be considered as 
missing.
(*) In case the date of death is present (complete date), the imputed progression date will be 
compared with the date of death. The minimum of the (imputed progression date, date of death) 
will be considered as the date of progression.
For date of last tumor assessment:

If only the day of the month is missing, the 1st of the month will be used to replace the missing 
day(*).

If the day and month are missing or a date is completely missing, it will be considered as 
missing.
(*) In case the date of death is present (complete date), the imputed date will be compared with 
the date of death. The minimum of the (imputed date, date of death) will be considered as the 
date of last tumor assessment.
Otherwise, missing values will not in general be imputed. Regardless of missing data, all subjects 
will contribute to the calculation of the following tumor response endpoints (as detailed in 
Sections 4.2.3-4.2.6): BORR and disease control rate (by inclusion in the denominators); and in 
the Kaplan-Meier analyses (by censoring, as appropriate) of DoR (for subjects with confirmed CR 
or PR), DoSD (for subjects whose BOR is SD) and PFS.
Conventions for EQ-5D:
The EQ-5D descriptive system will be converted into a single summary index score which 
provides a simple measure of health on a scale of 0 to 1 (0 = death and 1 = perfect health) as 
follows12:
X = 1 - 0.146016*MO2 - 0.557685*MO3 - 0.1753425*SC2 - 0.4711896*SC3 -
0.1397295*UA2 - 0.3742594*UA3 - 0.1728907*PD2 - 0.5371011*PD3 - 0.156223*AD2 
- 0.4501876*AD3 + 0.1395949*D1 - 0.0106868*I2^2 + 0.1215579*I3 + 0.0147963*I3^2,
where 

MO2, SC2, UA2, PD2, and AD2 are dummy variables for level 2 in dimensions mobility, self-
care, usual activities, pain/discomfort, and anxiety/depression, respectively;

MO3, SC3, UA3, PD3, and AD3 are dummy variables for level 3 in dimensions mobility, self-
care, usual activities, pain/discomfort, and anxiety/depression, respectively;

D1 is an ordinal variable: the number of movements away from Full health (1) beyond the first 
(i.e. it took on values ranging from 0 to 4);

I2 is an ordinal variable: the number of dimensions at level 2 beyond the first;

I3 is an ordinal variable: the number of dimensions at level 3 beyond the first.
