Turning Point Therapeutics Initiates Phase 1/2 Clinical Study of Repotrectinib in Pediatric Patients

SAN DIEGO, Nov. 12, 2019 (GLOBE NEWSWIRE) — Turning Point Therapeutics, Inc. (NASDAQ: TPTX), a precision oncology company developing novel drugs to address treatment resistance, today announced initiation of a Phase 1/2 clinical study of its lead drug candidate repotrectinib in pediatric patients with ALK-, NTRK– and ROS1-positive solid tumors.
“The initiation of our study in pediatric cancer patients expands the clinical development of our internally discovered and wholly owned pipeline of kinase inhibitors, now with three drug candidates in four clinical trials,” said Athena Countouriotis, M.D., president and CEO. “The pediatric study is an important milestone for Turning Point Therapeutics as we advance our work one step closer to bringing our targeted drug candidates to patients with oncogenic-driven cancers.”The study is anticipated to enroll approximately 12 patients in a Phase 1 dose-escalation portion and approximately 63 patients across three cohorts in a Phase 2 dose-expansion portion to assess NTRK-positive TKI-naïve tumors, NTRK-positive TKI-pretreated tumors, and ALK– or ROS1-positive tumors.Repotrectinib is Turning Point Therapeutics’ lead drug candidate, already being studied in a global registrational Phase 2 study. The new Phase 1/2 study is an open-label single-arm, multi-center clinical trial to evaluate the safety, tolerability, PK, and preliminary efficacy of repotrectinib in pediatric and young adult patients with advanced or metastatic solid tumors, primary CNS tumors, or anaplastic large cell lymphoma (ALCL) with ALK, ROS1, or NTRK alterations.Repotrectinib is an investigational next-generation TKI designed to target ROS1, TRK A/B/C, and ALK, and systemically overcome resistant mutations that result following treatment with other TKIs.About Turning Point Therapeutics Inc.
Turning Point Therapeutics is a clinical-stage precision oncology company with a pipeline of internally discovered investigational drugs designed to address key limitations of existing cancer therapies. The company’s lead program, repotrectinib, is a next-generation kinase inhibitor targeting genetic drivers of non-small cell lung cancer and advanced solid tumors. Repotrectinib, which is currently being studied in a registrational Phase 2 study in adults and a Phase 1/2 study in pediatric patients, has shown antitumor activity and durable responses among kinase inhibitor treatment-naïve and pre-treated patients. The company’s pipeline of drug candidates also includes TPX-0022, targeting MET, CSF1R and SRC, which is currently being studied in a Phase 1 trial of patients with advanced or metastatic solid tumors harboring genetic alterations in MET; and TPX-0046, targeting RET and SRC, which is currently being studied in a Phase 1/2 trial of patients with advanced or metastatic solid tumors harboring genetic alterations in RET. Turning Point’s kinase inhibitors are designed to bind to their targets with greater precision and affinity than existing therapies, with a novel, compact structure that has demonstrated an ability to potentially overcome treatment resistance common with other kinase inhibitors. The company is driven to develop therapies that mark a turning point for patients in their cancer treatment. For more information, visit www.tptherapeutics.com.Forward Looking Statements
