SOUTH SAN FRANCISCO, Calif., Nov. 03, 2023 (GLOBE NEWSWIRE) -- RAPT Therapeutics, Inc. (Nasdaq: RAPT), a clinical-stage, immunology-based therapeutics company focused on discovering, developing and commercializing oral small molecule therapies for patients with significant unmet needs in inflammatory diseases and oncology, today announced safety and efficacy data from its Phase 2 trial of FLX475 (tivumecirnon) in patients with advanced non-small cell lung cancer (NSCLC) who had no prior checkpoint inhibitor therapy. The trial evaluated FLX475, an oral small molecule CCR4 antagonist designed to block the migration of regulatory T cells, in combination with the checkpoint inhibitor pembrolizumab. In this cohort of NSCLC patients, 36 patients were evaluable for efficacy, of which 20 were PD-L1 positive. In these PD-L1 positive patients, the combination of FLX475 and pembrolizumab showed a 40% (8/20) confirmed ORR and a median PFS of 6.3 months as of the data cut off date, with seven patients continuing on study. For comparison, historical pembrolizumab monotherapy activity in checkpoint inhibitor-naïve and previously-treated NSCLC patients showed a confirmed ORR of 18% and a median PFS of 4.0 months. The confirmed ORR for the combination of FLX475 and pembrolizumab in PD-L1 low and high subsets were 38% (6/16) and 50% (2/4), respectively. For comparison, the ORR for pembrolizumab monotherapy in the PD-L1 low and high subsets has been previously reported as 10% and 30%, respectively.

Key Points: 
  • The trial evaluated FLX475, an oral small molecule CCR4 antagonist designed to block the migration of regulatory T cells, in combination with the checkpoint inhibitor pembrolizumab.
  • In this cohort of NSCLC patients, 36 patients were evaluable for efficacy, of which 20 were PD-L1 positive.
  • The confirmed ORR for the combination of FLX475 and pembrolizumab in PD-L1 low and high subsets were 38% (6/16) and 50% (2/4), respectively.
  • “We are excited by the response rates and PFS data for FLX475 in combination with a checkpoint inhibitor in this cohort of NSCLC patients.
