CAMBRIDGE, Mass., Aug. 10, 2022 (GLOBE NEWSWIRE) -- Tango Therapeutics, Inc. (NASDAQ: TNGX), a biotechnology company committed to discovering and delivering the next generation of precision cancer medicines, reported its financial results for the second quarter ended June 30, 2022 and provided business highlights.

“We are continuing to advance our lead MTA-cooperative PRMT5 inhibitor program, TNG908, as we actively enroll patients with MTAP-deleted solid tumors in an ongoing Phase 1/2 trial,” said Barbara Weber, M.D., President and Chief Executive Officer of Tango Therapeutics. “Receiving Orphan Drug Designation for TNG908 highlights the unmet need for novel therapies that may improve outcomes for patients with MPNST. We continue to progress IND-enabling studies of TNG462, our next-generation PRMT5 inhibitor, and TNG260, a small molecule inhibitor that reverses the immune evasion effect of STK11 mutations, as we advance both programs towards IND submission in the first half of 2023.”

Recent Business Highlights

• TNG908 Phase 1/2 clinical trial ongoing in patients with MTAP-deleted solid tumors; TNG908 received Orphan Drug Designation (ODD): Patients are actively being enrolled in the ongoing Phase 1/2 trial of TNG908. The Company expects to have initial safety and efficacy data in the 1H 2023.

The U.S. Food and Drug Administration (FDA) granted ODD to TNG908 for the treatment of malignant peripheral nerve sheath tumors (MPNST). The FDA's Orphan Drug Designation is granted to investigational therapies addressing rare medical diseases or conditions that affect fewer than 200,000 people in the United States. This designation provides for a seven-year marketing exclusivity period upon regulatory approval, as well as certain incentives, including federal grants and tax credits.

TNG908 is an MTA-cooperative small molecule inhibitor of protein arginine methyltransferase 5 (PRMT5) designed to selectively kill cancer cells with methylthioadenosine phosphorylase (MTAP) deletions. MTAP deletions occur in approximately 10% - 15% of all human cancers, including non-small cell lung cancer, mesothelioma, cholangiocarcinoma and glioblastoma.

  • TNG462, a next-generation MTA-cooperative PRMT5 inhibitor, declared as a development candidate in 2Q 2022: In May 2022, the Company disclosed TNG462, a next-generation PRMT5 inhibitor, is 45-fold more potent in cells with MTAP deletions than those without and induces deep tumor regressions in preclinical models of multiple cancer types. The Company plans to file an IND for TNG462 in the first half of 2023. The clinical development path for TNG462 is expected to be similar to TNG908, evaluating safety and efficacy in multiple tumor types in a Phase 1/2 clinical trial. Unlike TNG908, glioblastoma will be excluded from the clinical trial as TNG462 does not cross the blood-brain barrier in preclinical non-human primate models.

  • TNG260, a small molecule inhibitor that reverses the immune evasion effect of STK11 mutations, declared as a development candidate in 2Q 2022: Also previously disclosed by the Company, TNG260 was declared a development candidate in the second quarter of 2022. TNG260 inhibits Target 3, an undisclosed synthetic lethal target that reverses the immune evasion effect of serine-threonine kinase 11 (STK11) loss-of-function mutations in cancer models. The Company expects to file an IND for this program in the first half of 2023. STK11 mutations occur in approximately 15% of non-small cell lung cancers, 15% of cervical cancers, 10% carcinoma of unknown primary, 5% of breast cancers and 3% of pancreatic cancers.

  • Preclinical data on the Tango discovery platform, a USP1 inhibitor program and TNG908 presented at 2022 American Association for Cancer Research (AACR) Annual Meeting. In April, the Company presented three posters at the 2022 AACR Annual Meeting. The posters highlight the potential applicability of synthetic lethal drugs targeting across a range of cancer types, including with TNG908 and the USP1 (ubiquitin-specific protease 1) program.

  • TNGX added to the Russell 2000®, 3000® and Microcap® Indexes. In June 2022, as part of the Russell indexes annual reconstitution, Tango was added to the Russell 2000®, 3000® and Microcap® Indexes.
