“Ignyta, Inc. (RXDX),a precision oncology biotechnology company, today announced that updated results of its Phase 1 clinical trials of entrectinib, the company’s proprietary oral tyrosine kinase inhibitor targeting solid tumors harboring activating alterations to NTRK1, NTRK2, NTRK3, ROS1 or ALK, were presented in an oral plenary session at the 2016 Annual Meeting of the American Association for Cancer Research (AACR) in New Orleans, Louisiana.
“ ‘We continue to be excited by entrectinib’s ability to help patients with advanced cancer,’ said Jonathan Lim, M.D., Chairman and CEO of Ignyta. ‘With respect to efficacy, in the 25 patients in the Phase 1 trials who would meet the eligibility criteria for our Phase 2 clinical trial, we saw tumor regression in 20 patients, or 80%. Nineteen out of 24 patients with extracranial solid tumors had a confirmed RECIST response, representing a 79% overall response rate; and one patient with an astrocytoma had evidence of substantial tumor regression by volumetric measurement. These responses were observed in patients with each of NTRK, ROS1 and ALK rearrangements, and across six tumor histologies, including complete and/or durable responses in both primary and metastatic tumors of the central nervous system.’ ”
