SAN FRANCISCO and SUZHOU, China, June 7, 2022 /PRNewswire/ -- Innovent Biologics, Inc. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high-quality medicines for the treatment of oncology, autoimmune, metabolic, ophthalmology and other major diseases, and AnHeart Therapeutics ("AnHeart"), a clinical-stage global biopharmaceutical company committed to developing novel precision oncology therapeutics, today jointly announced updated efficacy and safety data from the Phase 2 TRUST clinical trial of taletrectinib in patients with ROS1-positive non-small cell lung cancer (NSCLC), at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting.
The Efficacy and Safety of Taletrectinib in TKI-naïve or Crizotinib-pretreated ROS1-positive Non-Small Cell Lung Cancer (NSCLC) Patients
Poster Presentation, Abstract #: 8572
The ongoing TRUST study (NCT04395677) is a multicenter, open-label, single-arm, Phase 2 study of taletrectinib in Chinese ROS1-positive NSCLC patients who are ROS1 tyrosine kinase inhibitor (TKI)-naive or crizotinib-pretreated.
As of February 23, 2022, the Phase 2 TRUST study has enrolled 67 TKI-naive and 42 crizotinib-pretreated patients. The patients were treated with taletrectinib 600 mg once daily and evaluated by independent review committee (IRC) for key efficacy endpoints including objective response rate (ORR), duration of response (DOR), disease control rate (DCR), intracranial objective response rate (IC-ORR), intracranial disease control rate (IC-DCR), progression-free survival (PFS), overall survival (OS), and safety.
Professor Caicun Zhou, Primary Investigator and Chief Oncologist at Shanghai Pulmonary Hospital, stated: "Taletrectinib is a potential best-in-class next-generation ROS1 inhibitor that is a much-needed new option to treat both ROS1-TKI-naïve and pre-treated NSCLC patients. The TRUST study showed high objective response rates in both the first-line and second-line settings in ROS1-positive NSCLC, with excellent potency against crizotinib-resistant mutations, including G2032R solvent front mutation. We're excited to see that taletrectinib has also demonstrated intracranial antitumor activity in patients with brain metastases."
Dr. Hui Zhou, Senior Vice President of Innovent, stated: "The updated ORR and DCR data of taletrectinib demonstrated its potential superior benefits in terms of both efficacy and safety for Chinese patients with ROS1-positive NSCLC. We are encouraged by the results and will move towards further clinical development of taletrectinib to explore the potential of the next-generation ROS1 inhibitor and benefit more NSCLC patients in the future."
Dr. Bing Yan, Chief Medical Officer and Co-Founder of AnHeart, stated: "Taletrectinib reported better brain penetration and intracranial activity in reference to other ROS1 inhibitors, with a favorable safety profile. We look forward to advancing taletrectinib, as we believe it is a potential best-in-class next-generation ROS1 inhibitor for both ROS1 TKI-naïve and pretreated NSCLC patients, who are in need for new therapeutic options that have antitumor activity against resistant mutations and brain metastases."
ROS1 oncogenic fusions are observed in ~1-2% NSCLC patients as well as in cholangiocarcinoma, glioblastoma, ovarian, gastric, and colorectal cancers. CNS metastasis occurs in 20-30% ROS1 TKI-naïve and in up to 50% of crizotinib-pretreated ROS1-positive NSCLC patients. Resistance to first-generation ROS1 inhibitors often occurs with secondary mutations such as ROS1 G2032R solvent front mutation, for which no FDA-approved therapy is available.
Taletrectinib is a next-generation, CNS-penetrant, selective ROS1 inhibitor. In March 2022, the NMPA grants Breakthrough Therapy Designation (BTD) to taletrectinib for both first-line TKI-naïve and second-line TKI-pretreated patients with ROS1-positive NSCLC. A separate global Phase 2 trial TRUST-II (NCT04919811) is actively enrolling patients at clinical sites in North America, Europe and Asia. The design of the TRUST-II study is presented in the poster (#TPS8601) at ASCO 2022.

About Taletrectinib (IBI344)
Taletrectinib is a novel best-in-class next-generation ROS1 inhibitor designed to effectively target ROS1 fusions with potential to treat both TKI-naïve and pre-treated patients. ROS1 rearrangement is estimated to be an oncogenic driver in approximately 1 to 2 percent of patients with NSCLC. ROS1 fusions are also observed in several other cancers such as cholangiocarcinoma, glioblastoma, ovarian, gastric, and colorectal cancers. Taletrectinib has demonstrated excellent potency against crizotinib resistance, good brain penetration and intracranial antitumor activity, and favorable safety profiles in ROS1 fusion-positive NSCLC patients. In these patients, few neurological adverse events were observed, which likely benefits from the selective inhibition of ROS1 over TRKB by taletrectinib.
