Turning Point Therapeutics and Almac Diagnostic Services announce approval of an investigational device exemption for the companion diagnostic assay to the registrational TRIDENT-1 clinical study

May 6, 2019

SAN DIEGO, May 6, 2019 – Turning Point Therapeutics, Inc. (NASDAQ: TPTX), a precision oncology company developing novel drugs that address treatment resistance, and Almac Diagnostic Services, a global stratified medicine company, today announced approval by the U.S. Food and Drug Administration (FDA) of an investigational device exemption (IDE) for the diagnostic assay that will be used in Turning Point’s registrational phase 2 clinical study.

The next-generation sequencing (NGS) assay is intended for use in identifying patients with ROS1, NTRK1-3 and ALK gene fusions in advanced solid tumors. Clinical investigators will use the diagnostic test to determine molecular eligibility for enrollment into Turning Point’s registrational Phase 2 portion of the global TRIDENT-1 clinical study.

“We are pleased to achieve this important milestone with our partner Almac, moving us closer to the start of our pivotal study for repotrectinib in the second half of 2019,” said Athena Countouriotis, M.D., president and chief executive officer. “With a clear unmet medical need for therapies that target genomic alterations in different cancers, the diagnostic assay will provide clinical investigators with timely information to confirm the presence of the oncogenic drivers we continue to study in patients with advanced solid tumors.”

Almac has been developing the NGS diagnostic based on Archer Dx’s Anchored Multiplex PCR (AMP™) chemistry, with the intent of submitting it for regulatory approval in the United States and using it initially at Almac’s CLIA-accredited laboratory in Durham, N.C. to identify tumors with the targeted gene fusions, enabling physicians to select appropriate patients for treatment with repotrectinib.

“We are very pleased to have been granted IDE approval by the FDA for the development and validation of this complex NGS diagnostic assay for its intended use as a clinical trial assay,” said Paul Harkin, President & Managing Director, Almac Diagnostic Services. “We are delighted to assist Turning Point Therapeutics with this important upcoming clinical study, and furthering our partnership to progress such a promising investigational therapy as repotrectinib.”

Repotrectinib is an investigational, next-generation tyrosine kinase inhibitor (TKI) developed for the treatment of patients with advanced solid tumors harboring ROS1, NTRK1-3 or ALK molecular rearrangements. Repotrectinib is a rationally designed, low molecular weight, macrocyclic TKI that is much smaller than current ROS1, TRK family and ALK inhibitors with the objective to systematically overcome the clinically acquired resistance mutations of ROS1, TRK family and ALK kinases, especially the gatekeeper and solvent front mutations.

Turning Point Therapeutics’ TRIDENT-1 Phase 2 open-label, multi-cohort study is planned for initiation in the second half of 2019.

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 has shown antitumor activity and durable responses among kinase inhibitor treatment-naïve and pre-treated patients, and is planned to enter a registrational Phase 2 study in the second half of 2019. 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.
