Company to present data from the global, pivotal Phase 2 TRUST-II study at the 2024 World Conference on Lung Cancer (WCLC)

Taletrectinib granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of ROS1-positive non-small cell lung cancer (NSCLC) and other NSCLC indications

Nuvation Bio Inc. (NYSE: NUVB), a late clinical-stage, global biopharmaceutical company tackling some of the greatest unmet needs in oncology, today announced multiple updates for its taletrectinib program. Data from the global, pivotal Phase 2 TRUST-II study has been accepted for an oral presentation at WCLC 2024 taking place September 7-10 in San Diego, California. Pooled data from both pivotal Phase 2 studies, TRUST-I and TRUST-II, has been accepted for a poster presentation at ESMO 2024 taking place September 13-17, in Barcelona, Spain. The pooled data presented at ESMO will support the Company’s NDA in the United States. Additionally, the U.S. FDA has granted Orphan Drug Designation to taletrectinib for the treatment of multiple NSCLC indications, including ROS1-positive NSCLC.

“We are excited to share these program updates as we continue toward our goal of bringing taletrectinib to patients with ROS1-positive NSCLC. We look forward to sharing the latest TRUST-II data at WCLC 2024 and pooled TRUST-I and TRUST-II data at ESMO 2024. The pooled data to be presented at ESMO will support our NDA in the U.S. and, we believe, position us to commercialize taletrectinib in 2025,” said David Hung, M.D., Founder, President, and Chief Executive Officer of Nuvation Bio. “Further, we are pleased with the FDA’s recent determination that taletrectinib qualifies for Orphan Drug Designation, which represents another key regulatory milestone for this important program.”

Taletrectinib was granted Orphan Drug Designation for the treatment of ROS1- positive, NTRK-positive, ALK-positive, LTK-positive, ACK1-positive, or DDR1-positive NSCLC. The FDA's Office of Orphan Drug Products grants this designation to support drug candidates in development for underserved patient populations or rare disorders that affect fewer than 200,000 people in the United States. Orphan Drug Designation qualifies a candidate for various development incentives, including tax credits for eligible clinical trials, waiver of application fees and potential market exclusivity for seven years upon FDA approval.

Taletrectinib is being evaluated for the treatment of patients with ROS1-positive NSCLC in two pivotal Phase 2 studies, TRUST-I (NCT04395677) in China and TRUST-II (NCT04919811), a global pivotal study.

About Taletrectinib

Taletrectinib is an oral, potent, central nervous system-active, selective, next-generation ROS1 inhibitor specifically designed for the treatment of patients with advanced ROS1-positive NSCLC. Taletrectinib is being evaluated for the treatment of patients with advanced ROS1-positive NSCLC in two Phase 2 single-arm pivotal studies: TRUST-I (NCT04395677) in China, and TRUST-II (NCT04919811), a global study. Taletrectinib has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of patients with ROS1-positive NSCLC and Breakthrough Therapy Designations by both the U.S. FDA and China’s National Medical Products Administration (NMPA) for the treatment of patients with advanced or metastatic ROS1-positive NSCLC. Based on results of the TRUST-I clinical study, China’s NMPA has accepted and granted Priority Review Designations to New Drug Applications for taletrectinib for the treatment of adult patients with locally advanced or metastatic ROS1-positive NSCLC who either have or have not previously been treated with ROS1 tyrosine kinase inhibitors (TKIs).

About ROS1-positive NSCLC

More than one million people globally are diagnosed with NSCLC annually, the most common form of lung cancer. It is estimated that approximately 1-3% of people with NSCLC are ROS1-positive. Up to 35% of people newly diagnosed with metastatic ROS1-positive NSCLC have tumors that have spread to their brain, increasing up to 55% for those whose cancer has progressed following initial treatment. While people with other types of lung cancer have seen great advances, there has been limited progress for people with ROS1-positive NSCLC who remain in need of new options.
