      181TiP - Phase II study of crizotinib in Japanese patients with advanced non-small cell lung cancer harboring a MET gene alteration: Co-MET study (ID 170)

      12:30 - 13:00  |  Author(s): Takashi Seto

      • Abstract

      Background

      The majority of non-small cell lung cancer (NSCLC) patients are diagnosed as metastatic disease for which no curative treatment is available. Phase III randomized trials of tyrosine kinase inhibitor (TKI) therapy for EGFR-mutant and anaplastic lymphoma receptor tyrosine kinase (ALK)-rearranged lung cancers have documented improvements in response and progression-free survival (PFS), and TKIs are approved for the treatment of patients with oncogene-driver mutations. c-Met is the tyrosine kinase receptor for hepatocyte growth factor, and MET gene alterations including MET exon14 skipping mutation-positive or MET high gene copy number are known to be an oncogene via activation of c-MET signaling pathway. Crizotinib is a selective ATP-competitive small-molecule inhibitor of c-Met, ALK and ROS1 tyrosine kinases. Durable responses to crizotinib were reported in patients with advanced NSCLC harboring MET exon 14 skipping mutation or high MET gene copy number. Therefore, we considered to assess the efficacy and safety of crizotinib in patients with advanced NSCLC harboring a MET gene alteration.

      a9ded1e5ce5d75814730bb4caaf49419 Trial design

      Co-MET is an open-label, multi-center, 2 cohort single-arm phase II trial of oral crizotinib in patients with advanced NSCLC harboring MET exon 14 skipping mutations without prior MET TKI treatment (cohort 1) or high MET gene copy number of 7 or more (cohort 2). The status of MET gene alterations will be determined using a validated RT-PCR assay and/or NGS. Crizotinib, 250 mg BID, will be administered orally continuously until disease progression or unacceptable toxicities. All tumor scans will be reviewed by an independent radiology committee according to RECIST version 1.1. The primary endpoint is objective response rate (ORR). Assuming a null hypothesis of a 20% ORR and an alternative hypothesis of a 50% ORR for cohort 1, and a one-sided type I error of 0.05 (one-side) and 80% power based on the exact binomial distribution, the required number of evaluable patients is 19. The sample size for cohort 2 is empirically set at 10 patients. Clinical trial information: UMIN000031623.

      Background

      Neurotrophic receptor tyrosine kinase (NTRK) gene fusions lead to the expression of chimeric TRK proteins with constitutively activated kinase function, conferring oncogenic potential across several tumour types. Entrectinib is a CNS-active, potent inhibitor of TRKA/B/C and ROS1. We present integrated efficacy and safety data for entrectinib in NTRK fusion-positive (NTRK-FP) solid tumours focusing on pts with NSCLC.

      a9ded1e5ce5d75814730bb4caaf49419 Methods

      Pts with locally advanced/metastatic NTRK-FP tumours (with or without baseline CNS disease) confirmed by nucleic acid-based methods, enrolled in global (>150 sites, 15 countries) phase 1/2 entrectinib trials (ALKA-372-001 [EudraCT 2012-000148-88], STARTRK-1 [NCT02097810], STARTRK-2 [NCT02568267]) were included. Disease burden was assessed per BICR using RECIST v1.1, after cycle 1 (4 wks) then every 8 wks. Primary endpoints: ORR, DOR by BICR. Secondary endpoints: PFS, OS, and safety.

      20c51b5f4e9aeb5334c90ff072e6f928 Results

      Outcomes in the total efficacy-evaluable population (n = 54; 10 tumour types, >19 histopathologies) are shown in the table; responses were seen in all tumour types, median PFS 11.2 mo. In the cohort of pts with NTRK-FP NSCLC (n = 10), BICR ORR was 70% (7/10). In NSCLC pts with CNS disease per investigator at baseline (n = 6), 4 had an intracranial response (2 complete, 2 partial); 1 had stable disease and 1 was not evaluable. In the safety population (68 pts with NTRK-FP solid tumors who received at least 1 dose of entrectinib), most treatment-related adverse events (TRAEs) were grade 1–2; grade 3: 32.4%, grade 4: 2.9%; no grade 5 TRAEs. TRAEs resulted in discontinuation in 4.4% and dose reduction in 39.7% of pts.

      fd69c5cf902969e6fb71d043085ddee6 Conclusions

      In this integrated analysis of global multicentre clinical trials, entrectinib was well tolerated and induced clinically meaningful, durable systemic and intracranial responses in pts with NTRK-FP solid tumours, including those with NSCLC. (Table).

      109O - Entrectinib in locally advanced or metastatic ROS1 fusion-positive non-small cell lung cancer (NSCLC): Integrated analysis of ALKA-372-001, STARTRK-1 and STARTRK-2 (ID 501)

      09:00 - 10:30  |  Author(s): Takashi Seto

      • Slides

      Background

      Entrectinib is a potent ROS1 inhibitor (as well as TRKA/B/C), designed to effectively penetrate the central nervous system (CNS); brain metastases are common in patients (pts) with advanced ROS1 fusion-positive NSCLC. Entrectinib achieves therapeutic levels in the CNS with antitumour activity in multiple intracranial tumour models. We present updated integrated safety and efficacy data from three Phase 1/2 entrectinib studies (ALKA-372-001 [EudraCT 2012-000148-88], STARTRK-1 [NCT02097810], STARTRK-2 [NCT02568267]) in pts with locally advanced/metastatic ROS1 fusion-positive NSCLC.

      a9ded1e5ce5d75814730bb4caaf49419 Methods

      The analysis included pts with ROS1 inhibitor-naïve NSCLC harbouring a ROS1 fusion identified via nucleic acid-based diagnostic platforms. The ROS1 safety-evaluable population included pts who received ≥1 dose of entrectinib; the integrated efficacy analysis included pts with at least 6 months of follow-up. Tumour assessments were done at wk 4 and then every 8 wks by blinded independent central review (BICR), using RECIST v1.1. Primary endpoints by BICR: overall response rate (ORR), duration of response (DOR). Key secondary endpoints: progression-free survival (PFS), safety. Additional endpoints: intracranial ORR (complete/partial response), DOR in pts with intracranial response, PFS in pts with or without baseline CNS disease.

      20c51b5f4e9aeb5334c90ff072e6f928 Results

      In the ROS1 safety-evaluable population (n = 134), at least one treatment-related AE (TRAE) of any grade was seen in 93% of pts. Pts with at least one TRAE by highest grade were: grade 1/2, 59%; grade 3, 31%; grade 4, 4%. There were no grade 5 TRAEs. TRAEs led to dose reduction or discontinuation in 34% and 5% of pts, respectively. Efficacy outcomes are summarised in the table.

      fd69c5cf902969e6fb71d043085ddee6 Conclusions

      Entrectinib is highly active in pts with ROS1 fusion-positive NSCLC, including pts with CNS disease. Entrectinib is well tolerated with a manageable safety profile.
