DEFINITIONS

Adverse event Any untoward or unfavorable medical occurrence in a human subject, including any abnormal sign (for example, abnormal physical exam or laboratory finding), symptom, or disease temporally associated with the subject’s participation in the research, whether or not considered related to the subject’s participation in the research, or any baseline conditions that worsened during the study.

Baseline value The last non-missing value recorded prior to the first dose of study drug.

Best overall response Patient’s best investigator-assessed RECIST response to treatment category recorded since the start of the treatment.

On study tumor assessments

Tumor assessments that meet the following criteria: 1. No gap of ≥91 days between successive tumor assessments among those on or prior to the on study tumor assessment. (Note: a tumor assessment for which “Not Evaluated” is entered into the database does not qualify as a tumor assessment.) 2. No prior initiation of non-protocol anticancer therapy.

Overall response rate The proportion of patients achieving a complete response or partial response to treatment.

Dose intensity The total dose (in mg) a patient actually received divided by the total dose (in mg) the patient should have received had there been no missed doses, dosing delays or dosage reductions.

Intent-to-treat population All patients randomized to receive study drug regardless of whether they actually received study drug and regardless of whether evidence is found indicating they failed to meet study inclusion/exclusion criteria or had other protocol violations.

Last contact date The last contact date is the latest assessment/visit date recorded on any of the following case report forms: Discontinuation, Hematology, Chemistry, RECIST Overall Response Tumor Assessments, Survival Follow Up, Study Drug Infusion, Etoposide Infusion or Platinum Therapy Infusion.

Non-Protocol Anti-Cancer Therapy

Non-protocol anti-cancer therapies used by patients during their participation in this study, if any, will be identified by the sponsor after review of relevant data listings.

Per-protocol population The subset of safety population who either (a) have at least one response evaluation on study, or (b) die prior to their first scheduled response evaluation.

Platinum Therapy / Platinum Choice

The physician’s choice of platinum therapy (cisplatin or carboplatin) was used as a stratification variable by the dynamic randomization system. Discrepancies, if any, between the platinum therapy used to stratify a patient’s treatment assignment and the platinum therapy actually administered during the study will be dealt with as follows. Platinum choice entered in the dynamic randomization system will be used in all efficacy analyses where platinum choice is included as a model

effect. However, actual platinum received (as documented on earliest Platinum Therapy Infusion CRF [e.g., Cycle 1, Day 1]) will be used when calculating dosing compliance.

Randomization Date Although each patient’s randomization date was recorded by site personnel on the Informed Consent case report form (CRF), the actual randomization date substantiated by the dynamic randomization system used to make blinded treatment assignments will be used in all analyses including calculations of times to events such as OS and PFS.

Randomized Study Drug Tarextumab or placebo Safety population The subset of the intent-to-treat population who received at least

one partial dose of tarextumab or Placebo and who have at least one post-dosing safety evaluation (labs, vital signs or adverse events).

Treatment-emergent adverse event

An adverse event that starts or increases in severity any time after the first administration of any randomized study drug (i.e., tarextumab or placebo) up to 30 days following the last administration of any study drug.

1. INTRODUCTION This document outlines the statistical methods to be implemented for analyzing data collected within the phase-2 portion of OncoMed Pharmaceuticals, Inc. Protocol 59R5-003 (A Phase-1b/2 Study of Tarextumab [OMP-59R5] in Combination with Etoposide and Platinum Therapy in Subjects with Untreated Extensive Stage Small Cell Lung Cancer), amendment 6 dated 22 April 2016. The purpose of this statistical analysis plan (SAP) is to provide specific guidelines from which the statistical analyses will proceed. Any deviations from this plan will be documented in the clinical study report (CSR). The definitive analyses of efficacy data for making statistical inference with respect to the objectives the Phase-2 portion of the study and the definitive analyses of safety data will be performed using data from a formal data cut taken planned to occur in April 2017. Randomized treatment assignments will be unblinded at that time. Any subsequent data analyses that may be performed to include data accrued into the database following the April-2017 data cut will be considered secondary efficacy and/or safety analyses.

Investigating the pharmacokinetics (PK) of tarextumab in combination with EP is an objective of this study, but a detailed analysis plan is outside the scope of this document.

Throughout this SAP, the terms patient and subject are used synonymously to refer to an individual who was enrolled to participate in the clinical trial.

2. STUDY OBJECTIVES

2.1. Primary Objectives The primary objectives of this study are:

Phase-1b portion: To determine the maximum tolerated dose (MTD) of tarextumab when administered on Day 1 of each 21 day cycle along with etoposide 100 mg/m2 on Days 1, 2 and 3 and cisplatin 80 mg/m2 or carboplatin to an area under curve (AUC) of 5 mg/mL/min on Day 1 in subjects with untreated extensive stage small cell lung cancer (ES-SCLC).

Phase-2 portion: To determine the improvement in progression free survival (PFS) resulting from the addition of tarextumab to etoposide and platinum therapy (EP) in subjects receiving first-line therapy for ES- SCLC. (Platinum therapy for the phase-2 portion was similar to phase-1b [i.e., cisplatin or carboplatin], but the cisplatin dose was changed to 75 mg/m2.)

Statistical analyses concerning the primary objective for the phase-1b portion of this study will not be addressed in this SAP.

2.2. Secondary Objectives The secondary objectives of this study are:

Phase-1b and -2 portions: To determine the PK of tarextumab in combination with EP in subjects receiving first-line therapy for ES-SCLC

Phase-1b and -2 portions: To determine the immunogenicity of tarextumab in combination with EP in subjects receiving first-line therapy for ES-SCLC

Phase-2 portion: To estimate the improvement in overall survival (OS), 12-month survival and overall response rate (ORR) resulting from the addition of tarextumab to EP in subjects receiving first-line therapy for ES-SCLC

Confidential Page 9/149

Phase-2 portion: To correlate the treatment effect in PFS, OS, 12-month survival and ORR resulting from the addition of tarextumab to EP in subjects with Notch3, Hey2, Hes1, Hey1 and Hes6 expression

Phase-1b portion: To determine the safety and tolerability of tarextumab in combination with EP in subjects who are receiving first-line therapy for ES-SCLC

Phase-2 portion: To compare the safety and tolerability of tarextumab in combination with EP relative to EP alone in all subjects who are receiving first-line therapy for ES-SCLC

Statistical analyses concerning the secondary objectives for the phase-1b portion of this study will not be addressed in this SAP.

2.3. Exploratory Objective An exploratory objective of this study is:

Phase-1b and -2 portions: To describe the changes in exploratory pharmacodynamic biomarkers, including Notch pathway related genes and proteins and circulating tumor cells following tarextumab treatment

3. STUDY DESIGN AND PLAN The following descriptions of the study design and plan were copied from the study protocol. Since this SAP only covers analyses planned for the phase-2 portion of the study, some portions of the study design and plan related only to the phase-1b portion were omitted intentionally.

The study consists of a phase-1b lead-in portion to determine the MTD of tarextumab in combination with EP for 6 cycles followed by treatment with tarextumab alone until unacceptable toxicity or disease progression. The initial dose escalations of tarextumab will be conducted with etoposide and cisplatin. The dose of tarextumab will not exceed 15 mg/kg. Following the establishment of the highest tolerable dose of tarextumab in combination with etoposide and cisplatin, a cohort of 6 subjects will be treated at this dose in combination with etoposide and carboplatin. Once the safety and tolerability of tarextumab at this dose is also confirmed with etoposide and carboplatin, the protocol will transition to a phase-2, multicenter, randomized, placebo-controlled portion comparing the efficacy and safety of tarextumab at the highest tolerable dose in combination with EP for 6 cycles followed by single agent tarextumab relative to EP alone for 6 cycles in subjects receiving first-line therapy for ES-SCLC. However, if a DLT is observed in 2 or more subjects in the cohort of 6 subjects treated with the highest tolerable dose of tarextumab with etoposide and carboplatin, a new cohort of 3 to 6 subjects will be enrolled at the next lower dose level of tarextumab with etoposide and carboplatin. The highest tarextumab dose that is tolerable with both platinum options will be used in phase-2 portion of the study.

In phase-2 portion of the study, subjects may be treated with cisplatin or carboplatin as determined by the investigator prior to randomization. Alteration to the choice of platinum therapy is not permitted once the subject is randomized.

Etoposide 100 mg/m2 will be administered on Days 1, 2 and 3 along with cisplatin 80 mg/m2 for phase-1b and 75 mg/m2 for the phase-2 portion of the study or carboplatin to an AUC of 5 mg/mL/min on Day 1 of every 21-day cycle for 6 cycles, tarextumab or placebo will be given on Day 1 of every 21-day cycle prior to the administration of EP.

Subjects may continue one of the chemotherapy drugs if the other is held or discontinued prior to completing 6 cycles of EP and prior to disease progression. Subjects should continue EP alone for a total of 6 cycles if tarextumab is held or discontinued prior to the completion of 6 cycles of EP. Subjects may continue study drug if one or both of the chemotherapy drugs is held or discontinued prior to completing 6 cycles of EP and prior to disease progression.

The phase-2 portion of the study may commence after the safety and tolerability of the highest tolerable dose of tarextumab has been confirmed in both cohorts of subjects with etoposide and cisplatin/carboplatin during phase-1b. The highest tarextumab dose that is tolerable with both platinum options will be used in the phase-2 portion of the study. For example: if tarextumab at 15 mg/kg is tolerable with etoposide and cisplatin, but not tolerable with etoposide and carboplatin; and tarextumab at 12.5 mg/kg is tolerable with etoposide and carboplatin, then tarextumab at 12.5 mg/kg will be the dose used in phase-2. The phase-2 portion includes a blinded treatment phase and follow-up phase. It is a multicenter, randomized, placebo-controlled portion evaluating the efficacy and safety of tarextumab in combination with etoposide and platinum therapy in subjects with previously untreated ES-SCLC. Subjects may be treated with cisplatin or carboplatin as determined by the Investigator prior to randomization. Alteration to the choice of platinum therapy is not permitted once the subject is randomized.

Approximately 135 evaluable subjects will be enrolled to the phase-2 portion of the study. Evaluable subjects are those who received at least one dose of study drug (either tarextumab or placebo).

Version 1.1 of standard response evaluation criteria in solid tumors (RECIST) criteria [Ref-1] was used to evaluate patients’ responses to treatment. RECIST response categories include complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD). In addition to these four primary ratings, a patient’s response to treatment is classified as unevaluable (abbreviated NE) when no imaging/measurement is performed at a particular time point.

3.1. Blinded Treatment Phase Subjects who qualify for enrollment into the phase-2 portion of the study will be randomized in a 1:1 ratio to receive study treatment of EP with placebo or EP with tarextumab. The randomization will be balanced on the choice of platinum therapy (cisplatin versus carboplatin) and the prior use of whole brain radiation (WBR) or prophylactic cranial irradiation (PCI). Changing the choice of platinum therapy is not permitted once the subject is randomized. Treatment for each subject will begin on Cycle1, Day 1 (the first dosing day). Etoposide 100 mg/m2 will be given on Days 1, 2 and 3 and cisplatin 75 mg/m2 or carboplatin to an AUC of 5 mg/mL/min will be given on Day 1 of every 21-day cycle for 6 cycles. Subjects may remain in the blinded treatment phase to continue one of the chemotherapy drugs if the other is held or discontinued prior to completing 6 cycles of EP and prior to disease progression. For subjects who have study drug held or discontinued for tolerability reasons, EP chemotherapy should continue to the completion of 6 cycles. Subjects may continue study drug if one or both of the chemotherapy drugs is held or discontinued prior to completing 6 cycles of EP and prior to disease progression.

After the completion of 6 cycles of EP, subjects who do not have disease progression and have not had WBR or PCI prior to study entry and are good candidates for PCI according to the

Page 11: Statistical Analysis Plan OncoMed Pharmaceuticals, Inc ... › ProvidedDocs › 41 › NCT01859741 › SAP_00… · 59R5-003 (Phase 2) 23MAR2017 Confidential Page 8/149 1. INTRODUCTION

investigator should receive PCI within 8 weeks after the last dose of chemotherapy at a total dose of 25 Gy in 10 fractions. If subjects discontinue EP with treatment-related toxicities prior to completing 6 cycles and are good candidates for PCI per the investigator, PCI can be initiated at any time determined appropriate by the investigator. Subjects who do not receive PCI within 8 weeks after the last dose of chemotherapy can have PCI later during the study as determined by the investigator. Study drug (tarextumab or placebo) administration should continue at every 21-day cycle between the completion of chemotherapy and the initiation of PCI. PCI should not be initiated within 2 weeks of study drug administration and study drug will be held during the PCI treatment period. Subjects will resume study drug alone ≥14 days after completion of PCI, until disease progression or unacceptable treatment-related toxicities or withdrawal of consent. Subjects will discontinue study treatment if there is evidence of central nervous system (CNS) metastasis.

3.2. Follow-Up Subjects who discontinue study treatment for any reason other than disease progression will be followed with tumor assessment every 6 weeks (42 ±5 days) during follow-up until documented disease progression or initiation of new anti-cancer therapy, whichever is sooner. Additionally, subjects who are discontinued from study treatment will be followed for survival and any subsequent anti-cancer therapies. Survival follow-up information and subsequent anti-cancer therapies, including systemic therapies, surgery (resection of metastatic disease), and radiation therapy will be collected during telephone calls, through subjects medical records, and/or clinic visits every 3 months starting from the last study treatment until death, loss to follow-up, or study termination by the sponsor. The study staff may use a public information source (e.g., county records) to obtain information about survival status only.

4. DETERMINATION OF SAMPLE SIZE The following assumptions and methods for determining the sample size for the study were copied from the study protocol. Since this SAP only covers analyses planned for the phase-2 portion of the study, details on the determination of sample size for the phase-1b portion of the study have been omitted intentionally.

At the final analysis we will evaluate the effect of tarextumab on PFS in subjects in the intention to treat (ITT) population (defined in section 6.1). The final analysis will take place when 91 progression events have been observed or 10 months after the completion of enrollment whichever occurs first.

Denote the treatment effect in terms of the log of the hazard ratio (HR) by . The null hypotheses for testing homogeneity of PFS distributions across treatment arms is:

And the alternative hypothesis is:

The power and type-1 error rate for the log rank test of this hypothesis is presented in Table 1.

[2] The boundary for rejecting the null hypothesis for harm is obtained from the gamma(-4) alpha spending function.

With 91 events at the final analysis, there is 80% power with 0.15 type 1 error to detect an HR of 0.67. There is a 7.6% chance of stopping early for harm under the null hypothesis; a 42.5% chance of stopping early for harm if the HR=1.33 (1/0.75); a 61.7% chance of stopping early for harm if the HR=1.49 (1/0.67); and a 94.1% chance of stopping early for harm if the HR=2.00 (1/0.5).

Analyses 1 and 2 will take place at the last two quarterly safety review meeting of the Data Safety Monitoring Board (DSMB). The estimated numbers of events at these times are presented in Table 1. If the number of events differs from what is presented, then the efficacy and safety boundaries will be recalculated using the spending functions which are footnoted in Table 1.

Overall survival is a secondary endpoint in this study. An analysis of OS will take place at the time of each analysis for PFS as well as at the time that the final analysis of PFS takes place. The final analysis of OS will take place when there are 98 events or 6 months after the final analysis for PFS, whichever occurs first. Table 2 and Figure 1 present enrollment, PFS events and Deaths over time assuming a control hazard of progression beyond 9 months of 0.1386.

Figure 1. Enrollment, Progressions and Deaths over Time – Control Hazard of Progression of 0.1386 Beyond 9 months

Calculations in Table 2 and Figure 1 take into account non constant hazards for PFS and OS described in Table 3 and Table 4, respectively. Estimates of non constant hazard are from Kaplan-Meier (KM) curves for PFS and Survival in Noda et al [Ref-2] and Hanna et al [Ref-3]. Regarding enrollment it was initially assumed that there is a ramp up time of 5 months with a starting enrollment of 4 subjects per months and that the maximum enrollment rate is 6 subjects per month. The enrollment in Table 10 and Figure 1 represents the observed enrollment up to January 2016 and the remaining enrollment is assumed to be 15 subjects per month.

The censoring rate was initially assumed to be 40% of the rate at which events occur in the control arm and 60% of the rate at which events occur in the tarextumab arm. When 79 PFS events accrued in the study, there were 39 censored observations for a censoring rate of 39/(39+79)=33%. This information was used to recalibrate the total number of events at the final analysis, the type 1 error rate and power.

We see from Table 2 that approximately 70% of the 98 deaths required for the final analysis of survival are expected to be observed at the time of the final analysis for PFS. Table 5 presents the power to detect benefit in OS for several HRs assuming that type 1 error is controlled at the 0.15 level and additional analyses take place at approximately 50%, 67% and 83% of full information. These additional analyses will take place at the quarterly DSMB review meetings. If the actual number of events at the review meetings differs from what is presented in the table, the efficacy and safety boundaries will be recalculated using the spending functions footnoted in Table 5.

[2] The boundary for rejecting the null hypothesis for harm is obtained from the gamma(-4) alpha spending function.

With 98 deaths at the final analysis, there is 80% power with 0.15 type 1 error to detect a HR of 0.682. There is a 7.4% chance of stopping early for harm under the null hypothesis, a 43.3% chance of stopping early for harm if the HR=1.33 (1/0.75); a 60.1% chance of stopping early for harm if the HR=1.47 (1/0.682); and a 95.0% chance of stopping early for harm if the HR=2.00 (1/0.5).

5. GENERAL ANALYSIS CONSIDERATIONS The statistical analyses will be reported using summary tables, figures and listings (TFLs). Unless otherwise noted, all statistical testing will be two-sided and will be performed at the 0.05 level of significance.

Continuous variables will be summarized with the number of non-missing values, estimated means, standard deviations, medians, 25th and 75th percentiles, and observed minimum and maximum values.

Categorical variables will be summarized by counts and by percentages. The percentage of patients within a category will be displayed in parentheses rounded to the nearest tenth of one percent. However, when the number of patients within a category is 0, then the percentage (i.e., 0.0%) will be omitted.

Time-to-event variables will be summarized by KM estimates of quartiles, observed minimum and maximum values, and the number of censored observations. The hazard will be estimated by the sum of all individual follow-up times in days divided by 365.25.

Any durations of time expressed in months will be reported in proportional “months” according to the formula

months days.

Summary tables will be presented by treatment group. Individual subject data will be presented in data listings.

The analyses described in this plan are considered a priori, in that they have been defined prior to database lock and prior to breaking the treatment blind. If any a posteriori analyses (i.e., analyses not included in this SAP) are performed, they will be identified as such in the CSR where the objective and rationale for executing any a posteriori analyses will be documented.

5.1. Analysis Software In general, data analyses and tabulations will be executed using SAS® version 9.2 or higher. SAS® programing statements will be validated by an independent programmer and SAS® output will undergo a senior-level statistical review to confirm that that all data manipulations and calculations are accurate and statistically valid methods have been implemented. Checks will be made to ensure accuracy and consistency with this plan and within and between TFLs. Upon

completion of validation and quality-review procedures, all documentation will be collected and filed by the project statistician or designee.

5.2. Baseline Values Unless otherwise noted, baseline is defined as the last non-missing value recorded prior to the first dose of study drug. Therefore, data collected during any unscheduled visits will be used in the determination of baseline values, as applicable.

5.3. Missing Values No imputations will be made for missing values. Summaries will be based on observed data only.

5.4. Subgroup Analyses Plans for analyses of subgroups based on the presence or absence of anti-tarextumab antibodies are presented in section 11.7 below.

No analyses by baseline characteristics or study center are planned.

Subgroup analyses by baseline Notch3, Hes1, Hey2, Hey1 and Hes6 expression levels are not planned, but the impact these potentially important covariates have on the efficacy of tarextumab will be assessed through statistical modeling (see sections 8.1, 8.3, 8.6 and 8.7).

5.5. Multiple Comparisons/Multiplicity A gamma(-12) spending function will be used to control the type-1 error for the assessment of efficacy and a gamma(-4) spending function will be used to control the type-1 error for harm arising from multiple analyses of PFS (see Table 1). The same spending functions will be used to control for multiplicity when testing OS (see Table 5).

6. ANALYSIS DATA SETS The analysis set for the phase-2 portion of the study will include data from all subjects who were randomized in the phase-2 portion to receive either tarextumab or control. Data from subjects who were enrolled in the phase-1b portion of the study will be excluded from the analysis set.

The planned data cut for the formal final analysis of PFS will take place at the point where 91 PD events have occurred or 10 months after the completion of enrollment, whichever occurs first. However, the actual data cut for the final formal analysis of PFS may be extended beyond 10 months after the completion of enrollment for reasons concerning study conduct (e.g., if patients are randomized but not treated). This will ensure that the study will have 81% power to detect an HR of 0.67 (improvement in median PFS from 4.8 months to 7.2 months) with an associated total one sided type-1 error rate of 0.15 (see section 4).

When the data cut for the formal analysis of PFS is taken, the following rules will be applied to determine which data are included in statistical analyses and data summaries. The goal of these data filtering rules is to ensure that that only certain data records occurring after the cutoff date 01-DEC-2016 are included.

1. No filter will be applied to the Death Report CRF or Follow Up After Discontinuation of Study Treatment CRF.

Page 17: Statistical Analysis Plan OncoMed Pharmaceuticals, Inc ... › ProvidedDocs › 41 › NCT01859741 › SAP_00… · 59R5-003 (Phase 2) 23MAR2017 Confidential Page 8/149 1. INTRODUCTION

OncoMed Pharmaceuticals, Inc. Statistical Analysis Plan 59R5-003 (Phase 2) 23MAR2017

Confidential Page 17/149

2. On CRF pages with a start/stop date (such as AE and CM), the data will be kept if either the start or stop date is on or prior to the cut off date. Note: if the start date is on or prior to the cut off, the record will be retained, therefore there may be stop dates that appear in listings that are post the cut off date.

3. If the outcome for an AE is death, the record will be retained even if the death occurred after the cut off date. Note: the record will be kept only for the purpose of preserving the death date (for efficacy analysis). The AE however will not be used in summaries of AEs.

4. In the event a partial date is reported and there is a chance the event/occurrence could be on or prior to the cutoff date, then that record will be kept for analyses and summaries. For instance, a record with a partial date of “2016” would be kept for analysis. Likewise, a record of “DEC-2016” would also be kept since the actual event date could have been 01DEC2016.

An additional data filtering rule specific to analyses of PFS and DOR is that deaths reported on the Death Report CRF and AE CRF where death is reported after the cut off date will not be considered.

Additional data filtering rules specific to analyses of OS are:

1. Death reported on Death Report CRF and AE CRF (end date of AE), regardless of date will be included in OS analyses. That is deaths reported after the cutoff date will not be filtered.

2. If the date of death reported on the Death Report CRF and an AE CRF is not the same, the date of death reported on the Death Report CRF will be used. SynteractHCR will notify the sponsor of the discrepancy.

3. The Follow-Up Discontinuation CRF does not explicitly collect date of death. The form only collects the Date of Survival Assessment and Last Known Survival Date. If a patient’s death is reported only on the Follow-Up Discontinuation CRF, then SynteractHCR will notify the sponsor, and the sponsor will advise SynteractHCR how to proceed.

Upon request, a listing of death dates can be generated to show which patients have died and which CRF page was used to acquire the death date.

The planned data cut for the final analysis of OS will be 6 months after the data cut for PFS or when 98 deaths have been observed, whichever occurs first. Once again, the actual data cut for the final formal analysis of OS may be extended beyond 6 months after the PFS data cut for reasons concerning study conduct.

6.1. Analysis Populations The following five groups of study patients will be used for statistical analyses.

1. The ITT patient population includes all patients randomized to receive study drug regardless of whether they actually received study drug and regardless of whether evidence is found indicating they failed to meet study inclusion/exclusion criteria or had other protocol violations. When the ITT patient population is analyzed, patients are grouped according to

Page 18: Statistical Analysis Plan OncoMed Pharmaceuticals, Inc ... › ProvidedDocs › 41 › NCT01859741 › SAP_00… · 59R5-003 (Phase 2) 23MAR2017 Confidential Page 8/149 1. INTRODUCTION

Confidential Page 18/149

their randomized treatment regardless of actual treatment received. The ITT patient population is the analysis population for demographics and baseline characteristics and for all statistical inference and primary tests of hypotheses related to efficacy endpoints.

2. The safety patient population is the subset of ITT patients who received at least one dose of study drug. When the safety patient population is analyzed, patients are grouped according to actual treatment received. Tarextumab is considered a patient’s “treatment received” in the safety patient population if the patient received at least one dose of tarextumab (complete or incomplete dose) any time during the study. The safety patient population is the analysis population for all analyses of safety data.

3. The per-protocol (PP) patient population is the subset of safety patients who either (a) have at least one response evaluation on study, or (b) die prior to their first scheduled response evaluation. When the per-protocol patient population is analyzed, patients are grouped according to actual treatment received. The per-protocol population is used for sensitivity (secondary, supportive) analyses of efficacy endpoints.

4. The pharmacokinetic (PK) patient population is comprised of all subjects who received at least one complete dose of tarextumab and have at least one post-dose PK sample.

5. The immunogenicity patient population is comprised of all subjects who had a baseline and one or more follow-up samples obtained for quantifying anti-tarextumab antibody.

7. SUMMARIES OF PATIENT CHARACTERISTICS

7.1. Subject Disposition Subject disposition information will be summarized for all subjects by treatment arm. Summaries will include the number of subjects randomized, the number of subjects in each analysis population, the primary reason for stopping each study drug (randomized treatment [tarextumab or placebo], selected platinum therapy [cisplatin or carboplatin] and etoposide), and the primary reason for withdrawing from the study.

The physician’s choice of platinum therapy (cisplatin or carboplatin) was used as a stratification variable by the dynamic randomization system. The actual platinum received (as documented on earliest Platinum Therapy Infusion CRF [e.g., Cycle 1, Day 1]) will be summarized in a 2x2 frequency table against the platinum-therapy strata under which a patient was randomized.

7.2. Protocol Deviations Protocol deviations will be collected and provided by the sponsor. Major protocol deviations that could potentially affect the integrity of efficacy/safety analysis results will be identified prior to database lock and categorized. Major protocol deviations categories may include, but are not limited to enrollment violations, dosing violations, prohibited concomitant therapy violations, and continuation of therapy when treatment should have been discontinued. Major protocol deviations will be summarized by deviation category and treatment group.

7.3. Demographics and Baseline Characteristics Demographic variables include age, sex, child-bearing potential for females, ethnicity and race. Age will be calculated in years relative to the informed consent date. Baseline characteristics include height, weight, body mass index (BMI), smoking history and Eastern Cooperative

Oncology Group (ECOG) performance status. Descriptive statistics will be presented for age, height and weight; and frequency counts and percentages will be presented for sex, child-bearing potential, ethnicity, race, smoking history (never smoked, ex-smoker, or current smoker) and ECOG performance status. Demographic and baseline characteristics will be summarized for the ITT, safety, PP and immunogenicity populations.

ES-SCLC history, including time since ES-SCLC diagnosis, histological/cytological type (small cell only, mixed type, or other), anatomical location of primary tumor, and number of disease sites (1, 2 or ≥3) at study entry will be summarized by treatment group for the ITT and safety populations. The time from ES-SCLC diagnosis to randomization will be quantified in months according to the formula shown in section 5. Summary statistics for baseline values of total tumor length (abbreviated SLD for sum of longest diameters) will be included in the analyses of efficacy endpoints.

Baseline levels of Notch3, Hes1, Hey2, Hey1 and Hes6 will be summarized as a continuous variable in the ITT, safety and per-protocol populations.

Prior therapies (surgeries and radiotherapies) for ES-SCLC will be summarized for the ITT and safety populations.

Patients’ medical and surgical histories will be displayed in a data listing.

8. EFFICACY ENDPOINTS Primary analyses of efficacy endpoints will use data from the ITT population. Additional efficacy analyses will be performed using data from only the PP population, but these analyses are considered secondary.

Efficacy endpoints include investigator-assessed PFS, assessment of SLD as a continuous variable, ORR defined as the proportion of patients achieving a CR or PR, duration of response (DOR), sites of progression, OS and landmark survival at 180, 360, 540 and 720 days.

As mentioned in section 5 above,

Continuous variables will be summarized with the number of non-missing values, estimated means, standard deviations, medians, 25th and 75th percentiles, and observed minimum and maximum values.

Categorical variables will be summarized by counts and by percentages. The percentage of patients within a category will be displayed in parentheses rounded to the nearest tenth of one percent. However, when the number of patients within a category is 0, then the percentage (i.e., 0.0%) will be omitted.

Time-to-event variables will be summarized by KM estimates of quartiles, observed minimum and maximum values, and the number of censored observations. The hazard will be estimated by the sum of all individual follow-up times in days divided by 365.25.

8.1. Progression-Free Survival On study tumor assessments are those that meet the following criteria:

Page 20: Statistical Analysis Plan OncoMed Pharmaceuticals, Inc ... › ProvidedDocs › 41 › NCT01859741 › SAP_00… · 59R5-003 (Phase 2) 23MAR2017 Confidential Page 8/149 1. INTRODUCTION

OncoMed Pharmaceuticals, Inc. Statistical Analysis Plan 59R5-003 (Phase 2) 23MAR2017

Confidential Page 20/149

1. No gap of >91 days between successive tumor assessments among those on or prior to the on study tumor assessment. (Note: a tumor assessment for which “Not Evaluated” is entered into the database does not qualify as a tumor assessment.)

2. No prior initiation of non-protocol anticancer therapy.

PFS, the primary endpoint of the study, is defined as the time from randomization (Day 1) until the first occurrence of death or disease progression based on investigator assessments of tumor response per the RECIST criteria. Progressions that are not determined from on study tumor assessments as well as deaths occurring more than 49 days from the last on-study tumor assessment are not treated as progression events. Subjects without a progression event will be censored at their last on study tumor assessment.

In addition two special cases will be handled in a manner consistent with the above rules as follows:

1. Patients whose first tumor assessment is >91 days from randomization will be censored on the date of randomization with a PFS of 1 day.

2. Patients who never had an on study tumor assessment and who did not die within 49 days (the scheduled time between tumor assessments plus 7 days) after randomization will be censored on the date of randomization with a PFS of 1 day.

The KM method will be used to estimate the proportions of subjects over time without progression or death and the median progression-free survival time. KM curves will be plotted by treatment group. The 95% confidence intervals for median progression-free survival time will also be calculated for each treatment arm. The p-value for treatment effect will be generated using a stratified log rank test using platinum choice (cisplatin or carboplatin; see page 6) and prior treatment modality (WBRT or PCI) as stratification factors. The HR and its 95% confidence interval will be estimated using a Cox proportional hazards (PH) model with main effects for treatment and the aforementioned stratification factors.

According to the study design, administrations of randomized treatment (tarextumab or placebo only; without EP) may continue in 21-day cycles from the completion of 6 cycles of EP until the initiation of PCI. The following analysis of PFS will be conducted in order to determine if there is a treatment benefit when tarextumab is administered in combination with EP. Subjects who have not progressed will have their PFS censored 35 days (the scheduled time for 1 treatment cycle plus 7 days) following the last dose of Carboplatin/Cisplatin or EP. KM and Cox PH analyses will be the same as those described above.

The impact of the biomarkers Notch3, Hes1, Hey2, Hey1 and Hes6 on PFS will be evaluated with a Cox PH model with treatment, biomarker and treatment-by-biomarker interaction included in the model as independent variables. A separate Cox PH model will be used for each biomarker.

Sensitivity analyses for PFS include replicating the primary log-rank analysis using the PP population and unstratified log-rank tests using the ITT and PP populations.

The planned timing for the primary analysis of PFS is stated in section 5.5 above.

8.2. Total Tumor Length Total tumor length is the sum of the longest diameters (SLD) for the target lesions as defined by RECIST criteria. Standard summary statistics for a continuous variable (identified in section 5) will be computed for SLD at baseline and the Cycle-3, Day-1 (C3D1) and Cycle-5, Day-1 (C5D1) assessments. Summary statistics will also be presented for changes from baseline at the C3D1 and C5D1 tumor assessments. Ninety-five percent confidence intervals for the mean SLD at each time point will also be computed. Two analysis of covariance (ANCOVA) models for SLD will be used to test the hypothesis that there is no difference between treatment arms with regard to changes in tumor length from baseline at the C3D1 assessment.

The difference between the follow-up and baseline SLD (e.g., SLDC3D1 – SLDbaseline) will be the dependent variable in the first ANCOVA model. Treatment, platinum choice (cisplatin versus carboplatin) and prior treatment modality (WBRT or PCI) will be categorical factors in the model, and SLDbaseline will be included as a continuous covariate.

The log of the ratio of follow-up to baseline SLD (e.g., log [SLDC3D1/SLDbaseline]) is the dependent variable in the ANCOVA model. Treatment, platinum choice and prior treatment modality will be categorical factors in the model, and log SLDbaseline will be included as a continuous covariate.

Missing values will not be imputed.

Separate but similar analyses will be performed for changes in tumor length from baseline at the C5D1 assessment.

A waterfall plot of best percent change in SLD across all tumor assessments relative to baseline will be presented.

Rates of change in SLD from baseline to C3D1, C5D1 and at progression will be evaluated.

The rate of change in SLD at CxD1 is defined as

where d2 is the number of days between the baseline assessment (Day 1) and the CxD1 assessment.

Rate of change in SLD at CxD1 will be missing for subjects who did not have a RECIST assessment corresponding to the CxD1 visit.

The rate of change in SLD from its on-study nadir to progression is defined as

where d1 is the number of days between the on-study SLD nadir and progression.

Rate of change in SLD at progression will be missing for subjects who did not have a RECIST assessment of PD on study and for subjects whose on-study SLDnadir = 0.

Confidential Page 22/149

Comparisons of these rates of change between the two treatment arms will be made using an analysis of variance (ANOVA) model with treatment, platinum choice (cisplatin versus carboplatin) and prior treatment modality (WBRT or PCI) as categorical independent variables.

8.3. Overall Response Rate A patient’s best overall response is defined as the best investigator-assessed RECIST response to treatment category recorded since the start of the treatment. The hierarchy of response ratings, best to worst, is CR, PR, SD, PD, followed by NE. The numbers and percentages of subjects achieving each of these response categories will be summarized within treatment group.

The ORR, defined as the proportion of patients achieving a CR or PR, and its 95% confidence interval will be computed within treatment group. The p-value for equality between treatment groups will be calculated for the two groups using a logistic regression model including treatment, platinum choice (cisplatin versus carboplatin) and prior treatment modality (WBRT or PCI) as categorical independent variables. Patients without any post-baseline tumor assessments will be classified among those never achieving a CR or PR.

The impact of the biomarkers Notch3, Hes1, Hey2, Hey1 and Hes6 on ORR will be evaluated with a logistic regression model with treatment, biomarker and treatment-by-biomarker interaction included in the model as independent variables. A separate logistic regression model will be used for each biomarker.

8.4. Duration of Response Analyses of DOR include only patients who achieved a CR or PR; patients failing to achieve a CR or PR during the study are omitted from analyses of DOR. If the number of patients achieving a CR or PR is not sufficient to produce meaningful KM curves, then the planned analyses for DOR may be abandoned.

DOR is defined as the number of days from the first CR or PR until the first occurrence of death or disease progression based on investigator assessments of tumor response per the RECIST criteria. Progressions that are not determined from on study tumor assessments as well as deaths occurring more than 49 days from the last on-study tumor assessment are not treated as progression events. Subjects achieving a CR/PR but without a subsequent progression event will be censored at their last on study tumor assessment.

In addition two special cases will be handled in a manner consistent with the above rules as follows:

1. Patients whose next tumor assessment (following the first CR/PR) is >91 days after the first CR/PR will be censored on the date of the first CR/PR with a DOR of 1 day.

2. Patients who never had an on study tumor assessment after the first CR/PR and who did not die within 49 days (the scheduled time between tumor assessments plus 7 days) after the first CR/PR will be censored on the date of first CR/PR with a DOR of 1 day.

The KM method will be used to estimate the proportions of CR/PR patients over time who have not experienced RECIST disease progression and the median DOR.

treatment effect will be generated using a Cox PH model with main effects for treatment, platinum choice (cisplatin versus carboplatin) and prior treatment modality (WBRT or PCI).

8.5. Sites of Progression Sites of progression will be categorized as stemming from (1) a new lesion or (2) progression of an existing lesion. Treatment-group distributions based on this binomial categorization will be tested using a chi-square test. Then “new lesions” will be further categorized by anatomical site. Patients with new lesions at multiple anatomical locations will be classified as a single category. The resulting multinomial distributions will also be compared across treatment groups using a chi-square test.

8.6. Overall Survival OS is defined as the number of days from randomization (Day 1) until death. The following rules will be used to define censored observations and censoring times for OS.

1. A patient for whom no death date is reported will have OS censored on the last contact date (defined on page 6). When evaluating the last contact date using the ‘Follow-Up After Discontinuation of Study Treatment’ CRF, both of the ‘date of survival assessment’ (if checked ‘alive’ for ‘subject status’) and the ‘last known survival date’ (if checked ‘alive or ‘lost to follow-up’ for ‘subject status) will be considered.

2. Patients lacking data after randomization who do not die have their event time censored on the date of randomization with duration of 1 day.

3. All patients alive on the date of the 98th sequential patient death will have their OS censored on the day following the date on which the 98th patient died. All patient deaths will be counted towards the total of 98, independent of which treatment arm the deceased patients were randomized to.

The KM method will be used to estimate survival proportions over time. KM survival curves will be plotted and 95% confidence intervals for median OS will also be calculated for each treatment arm. The HR, its 95% confidence interval and the p-value for testing the statistical significance of the treatment effect will be generated using a Cox PH model with main effects for treatment, platinum choice (cisplatin versus carboplatin) and prior treatment modality (WBRT or PCI).

OS will also be analyzed separately for two subsets of ITT patients defined by platinum choice (cisplatin or carboplatin). In this case, the p-value for testing the statistical significance of the treatment effect will be generated using a Cox PH model with main effects for treatment and prior treatment modality only.

The impact of the biomarkers Notch3, Hes1, Hey2, Hey1 and Hes6 on OS will be evaluated with a Cox PH model with treatment, biomarker and treatment-by-biomarker interaction included in the model as independent variables. A separate Cox PH model will be used for each biomarker.

The planned timing for the primary analysis of OS is stated in section 5.5 above.

8.7. Landmark Survival KM estimates of OS at 180, 360, 540 and 720 days will be summarized. Comparisons between the two treatment groups will be made using independent Z tests.

9. EXPLORATORY ANALYSES An exploratory analysis was undertaken by the sponsor using blinded data to examine the relationship between PFS and the Notch pathway markers HES1, HES6 and NOTCH3. The biomarker values were normalized so that the distributions had mean 0 and variance 1, then a Cox PH model was fit using the three main effects, the three two-way interactions, and the three-way interaction as independent variables. Estimated coefficients are show in Table 6.

Judging statistical significance at the two-sided 0.05 level, the two statistically significant terms which included NOTCH3 were used to establish a NOTCH-3-ralated PFS index (N3RPI).

Patients were then split into two groups (High N3RPI or Low N3RPI) based on whether their score was above or below the median N3RPI (0.066), respectively. A patient whose N3RPI was equal to the median was placed into the Low N3RPI group. Patients in each of these two groups were then split into two additional groups (High NOTCH3 or Low NOTCH3) based on whether their score was above or below the overall median NOTCH3 value (–0.046), respectively. A patient whose NOTCH3 was equal to the median was placed into the Low NOTCH3 group.

The KM curves for PFS and for OS in these four subgroups are presented in Figure 2 and Figure 3, respectively. For patients with an N3RPI above the median N3RPI (i.e., High N3RPI), the difference in PFS between the High and Low NOTCH3 groups is associated with a p-value of 0.09.

Figure 3. Overall Survival Kaplan-Meier Curves for Patients with High and Low N3RPI

It is noteworthy that high NOTCH3 is trending to be beneficial for patients with low N3RPI, whereas high NOTCH3 appears to be detrimental when N3RPI is high. This prompted the exploratory hypothesis that NOTCH 3 inhibition with tarextumab will improve PFS and OS in patients who have high N3RPI. In the case where N3RPI is high, tarextumab may be able to reduce the detrimental effects associated with high Notch 3 expression.

The following exploratory analyses will be carried out to test this hypothesis. The analysis population (ITT or per-protocol) will be divided into two N3RPI groups: High N3RPI and Low N3RPI (as defined above). Independent Cox PH models will be fit to data from each of the two groups. The models will include effects for treatment (tarextumab or placebo), NOTCH3 value, and the interaction between treatment and NOTCH3. The treatment HR and a 95% CI for the HR will be estimated at the quartiles of the NOTCH3 distribution. The same analysis will be carried out for “high” and “low” patient subgroups based on each of the biomarkers (Hes1, Hes6, Hey1 and Hey2).

11. SAFETY ENDPOINTS Analyses of safety endpoints will use data from the safety population. Safety endpoints listed in the study protocol include adverse events (AEs), serious adverse events (SAEs), clinical laboratory parameters, and results from testing for anti-tarextumab antibodies. Other safety endpoints include vital signs and electrocardiogram (ECG) results.

11.1. Treatment Cycles and Dosing Dosing with tarextumab (or placebo), etoposide and EP will be summarized by the number of cycles of treatment administered (duration of treatment), the number of doses of each study medication, and the extent of exposure to each study medication. Placebo exposure will be summarized in tarextumab-equivalent units, that is, by the number of milligrams of tarextumab the placebo “replaced” during treatment-blinded dosing.

Body surface area (BSA) is determined for each visit. The latest assessment of BSA on or before each visit will be used to determine the protocol-specified amount of drug (mg) in a dose.

11.1.2. Dosing Compliance Dosing compliance is defined as the ratio of the number of doses administered to the number of doses planned according to the schedule outlined in the study protocol.

Dosing compliance

where Nplanned is the number of doses planned according to the schedule outlined in the study protocol and Nadministered is the number of doses the patient received.

Dosing compliance will be summarized as a continuous variable (see Section 5) and by the numbers of patients with 0% to <20%; 20% to <40%; 40% to <60%; 60% to <80%; 80% to <100%; and 100% compliance. The reasons for delaying and/or withholding doses randomized study drug, selected platinum agent and etoposide will also be summarized.

11.2. Adverse Events Reported AE terms will be mapped to preferred terminology using Medical Dictionary for Regulatory Activities (MedDRA) version 17.1. All reported events will appear in AE listings, however only treatment-emergent adverse events will be summarized. A treatment-emergent adverse event (TEAE) is an AE that starts or increases in severity any time after the first administration of any randomized study drug (i.e., tarextumab or placebo) up to 30 days following the last administration of any study drug. AE severity was rated by the investigator according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 criteria.

A separate summary will be produced for each of the AE subsets listed above. Additional summaries will be produced by CTCAE severity grade. Patients may have more than one TEAE per MedDRA SOC and/or PT. At each level of summarization, a patient is counted once if he or she reported one or more TEAEs at that level. In AE summaries by CTCAE severity grade, patients will be classified according to the highest reported CTCAE severity for a qualifying event.

11.3. Clinical Laboratory Parameters Clinical laboratory results (serum chemistry, hematology, coagulation and urinalysis) will be valued using conventional units of measurement and summarized by treatment group using descriptive statistics for baseline, maximum post baseline, minimum post baseline, and last observed values. Changes from baseline will also be summarized. All clinical laboratory results will be listed by patient.

11.7. Immunogenicity The incidence of anti-tarextumab antibody development in the tarextumab treatment group will be summarized with counts and proportions. In addition, the impact of detectable anti-tarextumab antibodies and neutralizing anti-tarextumab antibodies on the efficacy of tarextumab will be assessed by summarizing PFS and OS in the subgroups of patients with and without these anti-tarextumab antibodies. The impact of detectable anti-tarextumab antibodies and neutralizing anti-tarextumab antibodies on the safety of tarextumab will be assessed by comparing AE incidence rates in the subgroups of patients with and without these anti-tarextumab antibodies. However, these subgroup analyses may not be carried out if the number of subjects with or without anti-tarextumab antibodies does not provide reasonable estimates of PFS and ORR.
