Brief Summary:
This was a 2-arm, open-label, phase 2 study of pegylated arginine deiminase (ADI-PEG) 20 in subjects with relapsed sensitive or refractory small cell lung cancer (SCLC). ADI-PEG 20 was administered intramuscularly (IM) at a fixed dose of 320 IU/m\^2 once weekly for a 4-week cycle. The primary objective was to assess clinical efficacy with a primary endpoint of tumor response by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 after 4 weeks. Secondary objectives were to assess the safety, pharmacodynamics, and immunogenicity of ADI-PEG 20, as well as clinical efficacy with a secondary endpoint of overall survival.
Detailed Description:
Subjects were enrolled sequentially (non-randomized) into two separate cohorts in parallel. Cohort 1 comprised subjects with "sensitive" disease and Cohort 2 comprised subjects with "refractory" disease. Both cohorts received the same treatment regimen consisting of 4 weekly IM administrations of ADI-PEG 20 (320 IU/m\^2), followed by a 1-week follow-up (1 cycle). No dose adjustment was allowed. Additional treatment cycles were permitted in the absence of disease progression requiring other therapeutic interventions.
Each cohort was to be enrolled in 2 stages. In the first stage, 15 subjects were to be accrued in Cohort 1 and 12 subjects in Cohort 2. If ≥ 3 subjects met the primary endpoint in Cohort 1, then an additional 13 subjects were to be accrued in the second stage. If ≤ 2 subjects met the primary endpoint in Cohort 1, then the study was to be terminated and declared negative for Cohort 1. If ≥ 1 subject met the primary endpoint in Cohort 2, then an additional 4 subjects were to be accrued in the second stage. If no subjects met the primary endpoint in Cohort 2, then the study was to be terminated and declared negative. Additionally, if at any time a death or two grade 4 adverse events (AEs) that were definitely related or probably related to the study drug occurred, then the study was to be stopped.
