Primary Outcome Measures
NameTimeMethod
Identification of Safe-dose for the Phase 2 Double-blind Phase in the Lead-in PhaseCycle 1 of Lead-in Phase

Safe recommended Phase 2 dose was determined based on dose-limiting toxicities (DLT) in Cycle 1. A DLT was defined as any of the following occurring in Cycle 1: Grade 3 or greater nonhematologic toxicity that was considered related to either entinostat or erlotinib or a Grade 4 hematologic toxicity lasting more than 7 days and/or resulting in a dose delay. Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 scale was used where Grade 1=mild, Grade 2=Moderate, Grade 3=Severe, medically significant, Grade 4=life-threatening and 5=death. The dose that was found to be safe is reported.

4-Month Progression-free Survival (PFS) Rate in the Double-blind PhaseMonth 4

PFS rate at 4 months was defined as the percentage of participants who are progression-free at 4 months.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) by Severity in the Double-blind PhaseFirst dose of study drug to within 30 days past last dose (Up to 7 months)

An AE is defined as any untoward medical occurrence in a patient or clinical investigation patient administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. Worsening of a pre-existing medical condition was considered an AE if there was either an increase in severity, frequency, or duration of the condition or an association with significantly worse outcomes. A TEAE is an AE that starts after the administration of study drug.

A SAE is any AE that is fatal, life threatening, requires in-patient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth effect or other significant medical hazard.

TEAE severity was graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 scale where Grade 1=Mild, Grade 2=Moderate, Grade 3=Severe, medically significant, Grade 4=Life-threatening and 5=Death.

Tmax: Time to Cmax of Entinostat in the Lead-in PhaseDay 1 predose and 0.5, 1, 2, 4 and 6 hours after dose; Days 2 and 8 predose (entinostat alone); Day 15 predose and 0.5, 1, 2, 4, 6 and 24 hours after dose
AUC(0-last): Area Under the Concentration-time Curve From Time 0 to Last Quantifiable Concentration in the Lead-in PhaseDay 1 predose and 0.5, 1, 2, 4 and 6 hours after dose; Days 2 and 8 predose (entinostat alone); Day 15 predose and 0.5, 1, 2, 4, 6 and 24 hours after dose
Objective Response Rate (ORR) in the Double-blind PhaseMonth 6

ORR was defined as the percentage of participants who had confirmed complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) as assessed by the investigator. CR=disappearance of all target lesions; disappearance of non-target lesions and normalization of tumor marker level. PR=At least a 30% decrease in the sum of the longest diameter of target lesions, taking at reference the baseline sum longest diameter.

6-Month PFS Rate in the Double-blind PhaseMonth 6

PFS rate at 6 months is defined as the percentage of participants who are progression-free at 6 months.

Vital Sign Values: Heart Rate in the Double-blind PhaseDay 1 and 15 of each cycle to safety follow-up 30 days past last dose (up to 7 months)
Vital Sign Values: Respiration Rate in the Double-blind PhaseDay 1 and 15 of each cycle to safety follow-up 30 days past last dose (up to 7 months)
Vital Sign Values: Weight in the Double-blind PhaseDay 1 and 15 of each cycle to safety follow-up 30 days past last dose (up to 7 months)
Vital Sign Values: Systolic Blood Pressure in the Double-blind PhaseDay 1 and 15 of each cycle to safety follow-up 30 days past last dose (up to 7 months)
Vital Sign Values: Diastolic Blood Pressure in the Double-blind PhaseDay 1 and 15 of each cycle to safety follow-up 30 days past last dose (up to 7 months)
Number of Participants With Grade 3 or 4 Laboratory Variables in the Double-blind PhaseDay 1 and 15 of each cycle to safety follow-up 30 days past last dose (up to 7 months)

Laboratory tests included tests of Hematology and Chemistry. The individual laboratory values were graded by the investigator using the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 scale where Grade 1=Mild, Grade 2=Moderate, Grade 3=Severe, medically significant, Grade 4=Life-threatening and 5=Death.

Vital Sign Values: Temperature in the Double-blind PhaseDay 1 and 15 of each cycle to safety follow-up 30 days past last dose (up to 7 months)
Cmax: Maximum Plasma Concentration of Entinostat in the Lead-in PhaseDay 1 predose and 0.5, 1, 2, 4 and 6 hours after dose; Days 2 and 8 predose (entinostat alone); Day 15 predose and 0.5, 1, 2, 4, 6 and 24 hours after dose
AUC(0-24): Area Under the Concentration-time Curve From Time 0 to 24 Hours in the Lead-in PhaseDay 1 predose and 0.5, 1, 2, 4 and 6 hours after dose; Days 2 and 8 predose (entinostat alone); Day 15 predose and 0.5, 1, 2, 4, 6 and 24 hours after dose
