Roche (SIX: RO, ROG; OTCQX: RHHBY) announced positive data from the Phase I/II STARTRK-NG study, evaluating the investigational medicine entrectinib in children and adolescents with recurrent or refractory solid tumours with and without neurotrophic tyrosine receptor kinase (NTRK), ROS1 or anaplastic lymphoma kinase (ALK) gene fusions. The study showed entrectinib shrank tumours (objective response rate; ORR) in all children and adolescents who had NTRK, ROS1 or ALK fusion-positive solid tumours (11 of 11 patients), including two patients achieving a complete response.(1) Of the 11 patients, five patients with primary high-grade tumours in the central nervous system (CNS) had an objective response, including one patient with a complete response.(1) The safety profile of entrectinib was consistent with that seen in previous analyses.(1) Data will be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago on Sunday, 2 June, 2019, from 8:00 - 8:12 am CDT (Abstract 10009), and was part of yesterday’s official ASCO presscast.
"We are encouraged by the results we have seen with entrectinib in children with paediatric and adolescent cancers, including those with tumours in the brain," said Sandra Horning, MD, Roche's Chief Medical Officer and Head of Global Product Development. "The STARTRK-NG study underscores the importance of combining comprehensive genomic profiling with targeted therapies and supports our approach to providing people with personalised medicines developed specifically for their type of cancer."
Additional data for entrectinib across different tumour types and patient populations will also be presented at ASCO, highlighting the company's unique approach to personalised healthcare through advances in targeted therapies, diagnostics and data analytics:
Initial results from an integrated analysis of the Phase II STARTRK-2, Phase I STARTRK-1 and Phase I ALKA-372-001 trials, evaluating the efficacy of entrectinib in adults with solid tumours and CNS metastases, will be presented on Saturday, 1 June, 2019, in a poster session from 3:00 - 4:30 pm CDT (Abstract 3017).
Results from a Real World Data study, evaluating time-to-treatment discontinuation and progression-free survival as endpoints for comparative efficacy analysis of clinical trials of entrectinib and crizotinib for the treatment of people with ROS1-positive non-small cell lung cancer (NSCLC), will be presented during a poster session on Sunday, 2 June, 2019, from 8:00 - 11:00 am CDT (Abstract 9070).
The FDA recently granted Priority Review for entrectinib for both the treatment of paediatric and adult patients with NTRK fusion-positive, locally advanced or metastatic solid tumours who have either progressed following prior therapies or as an initial therapy when there are no acceptable standard therapies, and for the treatment of people with metastatic ROS1-positive NSCLC.(2) These NDAs are based on results from the integrated analysis of the Phase II STARTRK-2, Phase I STARTRK-1 and Phase I ALKA-372-001 trials, and data from the STARTRK-NG study. The FDA is expected to make a decision on approval by 18 August, 2019.(2)
About the STARTRK-NG study
STARTRK-NG is a Phase I/II open-label dose-escalation and expansion study evaluating the safety and efficacy of entrectinib in children and adolescent patients with no curative first-line treatment option, recurrent or refractory extracranial solid tumours or primary CNS tumours, with or without NTRK, ROS1 or ALK fusions.1 Response, assessed by Investigator, was classified as complete response (CR), partial response (PR), stable disease (SD) or progressive disease (PD) using Response Assessment in Neuro-Oncology (RANO) for CNS tumours, Response Evaluation Criteria in Solid Tumors (RECIST), and Curie score (CS) for NBL.(1) The study enrolled 29 children and adolescents aged 4.9 months through to 20 years (median age of 7 years) who had recurrent or refractory solid tumours, and 28 were evaluated for response.(1) Of the 28 children and adolescents evaluated, 11 children were identified to have tumours with NTRK, ROS1 or ALK fusions and one with ALK F1174L-mutated neuroblastoma (NBL).(1) A summary of the results are included below.
Complete responses were observed in 2 patients with tumours harbouring NTRK and ALK fusions: 1 with an NTRK fusion-pos...
