Trial Outcomes & Findings for Pemetrexed Disodium or Erlotinib Hydrochloride as Second-Line Therapy in Treating Patients With Advanced Non-small Cell Lung Cancer (NCT NCT00738881)

NCT ID: NCT00738881

Last Updated: 2015-10-29

Results Overview

Estimated using the method of Kaplan-Meier survival curves to compare PFS between the erlotinib and pemetrexed arms using an intent-to-treat (ITT) analysis. Due to the small sample size (21 of the required 954 patients \~2%), analyses within the FISH(+) and FISH(-) groups were not performed, and no formal analyses for the primary or the secondary efficacy outcomes were performed.

Participant Flow

Twenty nine (29) pre-registered, screen failures (4 inadequate tissue, 1 investigator decision and one patient decision). Twenty three (23) patients were randomized, 2 patients withdrew from study prior to receiving any study treatment, thus a total of 23 randomized patients are evaluable for the primary and secondary endpoints.

PRIMARY outcome

Timeframe: Time from randomization to the first date of documented disease progression or death, assessed up to 5 years

Population: All the 23 randomized patients are eligible for primary end point analysis using an ITT principle.

Estimated using the method of Kaplan-Meier survival curves to compare PFS between the erlotinib and pemetrexed arms using an intent-to-treat (ITT) analysis. Due to the small sample size (21 of the required 954 patients \~2%), analyses within the FISH(+) and FISH(-) groups were not performed, and no formal analyses for the primary or the secondary efficacy outcomes were performed.

Interval 1.2 to 4.2

SECONDARY outcome

Timeframe: The time from date of randomization to the date at which the patient is removed from the treatment, assessed up to 5 years

Population: Since the trial closed prematurely with only \~2% accrual, the secondary outcomes were not analyzed.

The distribution of all time to event data will be estimated using the method of Kaplan-Meier survival curves.

SECONDARY outcome

Timeframe: Time from randomization to time of death from any cause, assessed up to 5 years

Population: Since the trial closed prematurely with only \~2% accrual, the secondary outcomes were not analyzed.

Will be estimated using the method of Kaplan-Meier survival curves. A 1-sided stratified log rank test \[accounting for all the stratification factors except FISH status and cooperative group\] will be used to compare overall survival between the erlotinib and pemetrexed arms within the FISH(+) and FISH(-) subgroups, compare overall and progression free survival between the erlotinib and pemetrexed arms within the subgroups defined on the basis of the epidermal growth factor receptor (EGFR) expression by immunohistochemistry (IHC), and EGFR gene mutation status (MUT). Cox proportional hazards model will be used to assess potential differences.

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 5 years

Population: Since the trial closed prematurely with only \~2% accrual, the secondary outcomes were not analyzed.

Responses will be summarized by simple descriptive summary statistics delineating complete and partial responses as well as stable and progressive disease. The proportion of patients with confirmed CR and PR will be computed within each treatment arm and exact binomial confidence intervals for the true proportion computed. Chi-square test and Fisher's exact test will be used to compare the response rates between the treatment arms within the subgroups defined by FISH status, IHC, and MUT.
