Study of Pemetrexed Versus Pemetrexed Plus Erlotinib as Treatment of Nonsquamous Non-Small Cell Lung Cancer (NSCLC)

Eli Lilly and Company204 enrolled

Overview

This is a multicenter, randomized, Phase 2, open label, parallel trial to evaluate an effect of pemetrexed alone on nonsquamous non-small cell lung cancer (NSCLC) in a second-line setting (such as progression-free survival \[PFS\], disease control rate, best response rate, time to treatment failure \[TTTF\], overall survival \[OS\] and 1-year survival rates) compared to pemetrexed plus erlotinib combination.

Outcomes

Primary Outcomes

Progression Free Survival (PFS)

PFS per Response Evaluation Criteria in Solid Tumors (RECIST) 1.0 criteria using computed tomography (CT) or magnetic resonance imaging (MRI) for objective determination of progressive disease (PD: ≤20% increase in sum of longest diameter of target lesion). For participants alive as of data cut-off date who did not have PD, PFS was censored at date of last CT/MRI. For participants who received subsequent systemic anticancer therapy (after study discontinuation) prior to PD or death, PFS censored at date of last CT/MRI prior to initiation of post discontinuation systemic anticancer therapy.

Time frame: Baseline to date of measured PD or death from any cause. Maximum follow-up was from baseline to 32.2 months

Secondary Outcomes

Percentage of Participants With Best Response of Stable Disease (SD), Partial Response (PR) or Complete Response (CR) (Disease Control Rate)

Per RECIST: CR: Disappearance of all target lesions; PR: Either a) ≤30% decrease in sum of longest diameter (LD) of target lesions or b) complete disappearance of target lesions, with persistence (but not worsening) of ≥1 nontarget lesions. In either case, no new lesions may have appeared. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD taking as references the smallest sum LD. PD: ≤20% increase in sum of LD of target lesions. Disease Control Rate (%) = (SD+PR+CR)/number of participants in arm\*100.

Time frame: Baseline to measured PD. Maximum follow-up was from Baseline to 34 months

Percentage of Participants With Best Response of Complete Response (CR) or Partial Response (PR) (Response Rate)

CR: Disappearance of all tumor lesions; PR: Either a) at least a 30% decrease in sum of LD of target lesions or b) complete disappearance of target lesions, with persistence (but not worsening) ≥1 nontarget lesions. In either case, no new lesions may have appeared. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD taking as references the smallest sum LD. PD: ≤20% increase in the sum of LD of target lesions. Response Rate (%) = (CR+PR)/number of participants in arm\*100.

Time frame: Baseline to measured progressive disease. Maximum follow-up was from Baseline to 34 months

Time to Treatment Failure (TTTF)

Defined as the time from randomization to death from any cause, first observation of PD, or study treatment discontinuation due to any reason other than "protocol complete" or "satisfactory response". For participants who discontinued due to "protocol complete" or "satisfactory response", or for participants not known to have discontinued as of the data cut-off date, TTTF was censored at the last contact date.

Time frame: Baseline to first date among death from any cause, PD, or study treatment discontinuation for any reason other than "protocol complete" or "satisfactory response". Maximum follow-up was from Baseline to 32.2 months

Overall Survival (OS)

OS time is the duration from randomization to the date of death from any cause. For each participant who was not known to have died as of the data inclusion cut-off date, OS was censored at the date of last contact.

Time frame: Baseline to date of death from any cause. Maximum follow-up was from Baseline to 42.6 months.

Percentage of Participants Surviving at 1 Year

Overall Survival (OS) rate at 1 year from the date of randomization was determined using the distribution of OS times and was estimated using the Kaplan-Meier method.

Time frame: Baseline to date of death from any cause up to 1 year

Number of Participants With Adverse Events (AEs)

Summaries of serious AEs (SAEs) and all other non-serious AEs are located in the Reported Adverse Event Module.

Time frame: Baseline up to 42.2 months
