A Study of the Effect of R1507 in Combination With Tarceva (Erlotinib) on Progression-Free Survival in Patients With Stage IIIb/IV Non-Small Cell Lung Cancer (NSCLC) Having Received Tarceva Monotherapy.

Phase 2

Terminated

• Conditions: Non-Small Cell Lung Cancer
• Interventions: Drug: RG1507; Drug: erlotinib [Tarceva]

• Registration Number: NCT00773383
• Lead Sponsor: Hoffmann-La Roche

Brief Summary

This single arm study in patients with advanced Stage IIIb/IV NSCLC who have progressive disease after deriving clinical benefit (defined as response or stable disease after 12 weeks) from second or third line Tarceva monotherapy will determine the proportion of patients with progression-free survival at 12 weeks following combination therapy with R1507 and Tarceva. Patients will receive R1507 (9mg/kg iv) weekly in combination with Tarceva (150mg oral daily) for up to a maximum of 24 months. Other disease-related endpoints including overall survival, objective response rate, time to response, time to progressive disease and duration of response will also be evaluated. The anticipated time on study treatment is 1-2 years, and the target sample size is \<100 individuals.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants With Progression Free Survival (PFS)	12 weeks	The primary efficacy endpoint is progression-free survival at 12 weeks after start of therapy. A progression-free survival rate at 12 weeks will be calculated, with patients categorized in a dichotomous manner as alive and progression-free or in progression or dead at 12 weeks.

Secondary Outcome Measures

Name	Time	Method
Duration of Overall Survival	From start of treatment to death; up to the time that all participants ended treatment	The study was prematurely terminated due to discontinuation of R1507 development (not for safety reasons). As a result, data not provided for outcome measures listed.
Participants Achieving Objective Response	Patients were followed from start of therapy until date of first response	Objective response is defined as a complete response (CR) or partial response (PR) that has been confirmed by a second tumor assessment no earlier than 4 weeks after the initial documentation. Response is assessed using Response Evaluation Criteria in Solid Tumors (RECIST)criteria.; The study was prematurely terminated due to discontinuation of R1507 development (not for safety reasons). As a result, data not provided for outcome measures listed.
Time to Best Response	Patients were followed from start of therapy until date of first response	This is defined as time from the start of therapy to the date of first CR or PR.; The study was prematurely terminated due to discontinuation of R1507 development (not for safety reasons). As a result, data not provided for outcome measures listed.
Time to Progressive Disease (PD)	From start of therapy to the date of first documentation of PD. Pts who never progress prior to final analysis or are withdrawn from the study without documented progression will be censored at the date of the last valid tumor assessment.	The study was prematurely terminated due to discontinuation of R1507 development (not for safety reasons). As a result, data not provided for outcome measures listed.
Duration of Objective Response	from the date the complete or partial response was first recorded to the date which progressive disease is first noted or date of death. If a patient does not progress or die while being followed, the date of the last valid tumor assessment will be taken	This is defined similarly for complete and partial responders. Complete response or partial response lasts from the date the complete response or partial response was first recorded to the date on which progressive disease is first noted or date of death. If a patient does not progress or die while being followed, the date of the last valid tumor assessment will be taken. The study was prematurely terminated due to discontinuation of R1507 development (not for safety reasons). As a result, data not provided for outcome measures listed.
Baseline Electrocardiogram (ECG)	baseline within 28 days of starting treatment (screening visit).	Standard safety monitoring includes baseline Electrocardiogram (ECG).; The study was prematurely terminated due to discontinuation of R1507 development (not for safety reasons). As a result, data not provided for outcome measures listed. The study was prematurely terminated due to discontinuation of R1507 development (not for safety reasons). As a result, data not provided for outcome measures listed.
Fasting Glucose, Highest Post-Baseline Value	Baseline, Highest Post-Baseline value within the timeframe of post-baseline collection up to when patient discontinued (up to 59 weeks)	A fasting glucose was required at baseline, and random non-fasting glucose testing was performed weekly for the first 6 weeks followed by day 1 of each 3 week treatment phase. The number of participants with the highest post-baseline fasting glucose level at any time point post baseline relative to the participant's baseline glucose level is reported.
Hemoglobin A1c (HbA1c)	screening	Standard safety monitoring includes baseline Electrocardiogram (ECG), Fasting glucose and HbA1c, monthly urine pregnancy test in female patients of childbearing potential and Human anti-human antibody (HAHA) testing.; Data will be represented in the Serious Adverse Event (SAE) Adverse Event (AE) section of Protocol Registration System (PRS).
Monthly Urine Pregnancy Test in Female Patients of Childbearing Potential	Within 7 days of starting treatment (baseline visit)	Standard safety monitoring includes baseline Electrocardiogram (ECG), Fasting glucose and HbA1c, monthly urine pregnancy test in female patients of childbearing potential and Human anti-human antibody (HAHA) testing.; Not posted; it will be represented in the Serious Adverse Event (SAE) Adverse Event (AE) section of Protocol Registration System (PRS).
Number of Participants With Positive Results for Human Anti-human Antibody (HAHA) Testing	prior to dosing on week 1 (day 1), week 4 (day 22), week 10 (day 64), final visit, follow up visit and 12 weeks post last dose (up to 71 weeks)	Number of participants who tested positive for Human anti-human antibody (HAHA) testing for immunogenicity.; To determine HAHA specificity, screened positive samples were tested in a confirmatory assay in the presence of 10 ug/mL R1507. Samples with \> 19.7% inhibition were considered true positives, whereas those with \< 19.7% inhibition were considered to be false positives.
Electrocardiogram (ECG)	baseline and thereafter as clinically indicated at the discretion of the investigator up to the time that the patient discontinued (up to 59 weeks)	12 lead ECG is required at baseline and will be measured during the trial as clinically indicated at the discretion of the investigators. For each reading, QTcF value will be calculated as the QT value (seconds) divided by the cube root of the RR interval in seconds (Fridericia correction). A listing will be generated showing, for each patient, the visits at which ECGs were taken and the results (normal or abnormal, as well as any comments provided).
Population Pharmacokinetics of R1507 and Tarceva	Throughout study	Population PK of R1507 and erlotinib were planned but not analyzed due to the termination of the trial.
Assessment of Potential Predictive and Prognostic Biomarkers.	Throughout study	Total IGF-I, free IGF I/II and other potential biomarkers present in serum. Further putative biomarker analyses in blood and tumor samples were planned in the protocol for exploratory assessment of correlation with clinical outcome. None of these were analyzed due to the termination of the trial.
