Ignyta, Inc. (Nasdaq: RXDX), a biotechnology company focused on precision medicine in oncology, today announced that updated data on entrectinib – an investigational, CNS-active, potent and selective tyrosine kinase inhibitor being developed in tumors that harbor NTRK fusions or ROS1 fusions — will be presented at the International Association for the Study of Lung Cancer (IASLC) 18th World Conference on Lung Cancer (WCLC) in Yokohama, Japan on October 18, 2017. The oral presentation (abstract 8564) is entitled “Entrectinib in Patients with Locally Advanced or Metastatic ROS1 Fusion-Positive Non-Small Cell Lung Cancer (NSCLC).”

“We are excited to share updated ROS1 data from our ongoing clinical trials of entrectinib, including the registration-enabling STARTRK-2 trial, as we continue to move towards dual NDA submissions for entrectinib in 2018,” said Jonathan Lim, M.D., chairman and CEO of Ignyta. “In total, Ignyta has treated more than 70 ROS1 fusion-positive NSCLC patients with entrectinib across our Phase 1 and Phase 2 clinical trials, making it one of the largest clinical datasets evaluating efficacy in this patient population. In this difficult-to-treat cancer, we’ve seen how entrectinib can beneficially impact the lives of patients, and we hope these data will further demonstrate its compelling profile and potential role as a first-line targeted therapy in ROS1 NSCLC.”

A conference call and live webcast will be held on October 18, 2017 at 5:00 a.m. Pacific time (8:00 a.m. Eastern time) to discuss the data presented as well as the comprehensive entrectinib program. To participate in the conference call, please dial 800-946-0716 (U.S.) or 719-325-4934 (international) and provide Conference ID 7994148.

A replay of the presentation will be available shortly after the conclusion of the live call in the Investors section of the company’s website at https://www.ignyta.com/investors/, and will be archived and available at that site for 14 days.
