CAMBRIDGE, Mass., May 11, 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 first quarter ended March 31, 2022 and provided business highlights.

“We’ve had a strong start to 2022, including IND clearance and Fast Track Designation from the FDA for TNG908, our lead PRMT5 inhibitor program. We are making good progress advancing TNG908 into the clinic and expect to dose our first patient in the Phase 1/2 clinical trial for the treatment of MTAP-deleted solid tumors in the second quarter of this year,” said Barbara Weber, M.D., President and Chief Executive Officer of Tango Therapeutics. “Additionally, our development candidates, TNG462, a next-generation PRMT5 inhibitor for MTAP-deleted solid tumors and TNG260, an inhibitor of an undisclosed synthetic lethal target that reverses the immune evasion effect of STK11 loss-of-function mutations, are in IND-enabling studies. Finally, with a strong current cash position, we are confident in our ability to advance our programs into the second half of 2024.”

Recent Business Highlights

  • TNG908 IND cleared and granted Fast Track Designation (FTD); first-in-human clinical trial is now open for enrollment. As disclosed in February 2022, the U.S. Food and Drug Administration (FDA) granted FTD to TNG908, a synthetic lethal small molecule inhibitor of protein arginine methyltransferase 5 (PRMT5) designed to selectively kill cancer cells with methylthioadenosine phosphorylase (MTAP) deletions. FTD is designed to facilitate the development and expedite the review of drugs to treat serious conditions and fulfill an unmet medical need, with the potential to allow drugs to reach more patients faster.

    As disclosed in January 2022, the FDA cleared the Investigational New Drug (IND) application for TNG908. The Phase 1/2 clinical trial is now open for enrollment and the Company expects to have initial safety and efficacy data in the 1H 2023. Enrollment is limited to patients with confirmed MTAP-deleted solid tumors. 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 PRMT5 inhibitor, declared a development candidate in 2Q 2022: Given the large number of patients with MTAP-deleted cancers, Tango is investing in a PRMT5 franchise by developing a product candidate with increased potency, MTAP-deletion selectivity and longer target coverage. 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. Glioblastoma will be excluded from the clinical trial as TNG462 does not cross the blood-brain barrier in preclinical non-human primate models.
  • TNG260, an inhibitor that reverses the immune evasion effect of STK11 mutations, declared a development candidate in 2Q 2022: Inhibiting Target 3, an undisclosed synthetic lethal target, reverses the immune evasion effect of serine-threonine kinase 11 (STK11) loss-of-function mutations in cancer models. In syngeneic models with an STK11 mutation and an intact immune system, the combination of TNG260 with an anti-PD1 antibody resulted in sustained complete tumor regressions and the induction of immune memory against re-implantation of tumors. Tango expects to file an IND for this program in 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.
  • Presented preclinical data on TNG908, USP1 inhibitor program and discovery platform at 2022 American Association for Cancer Research (AACR) Annual Meeting. Last month, 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 TNG908 and the USP1 (ubiquitin-specific protease 1) program.
  • Presented preclinical TNG908 combination data at 2022 European Society for Medical Oncology (ESMO) Targeted Anticancer Therapies Congress. In March, the Company presented at the 2022 ESMO Targeted Anticancer Therapies Congress. The posters highlight the synergy between TNG908 and the KRAS inhibitor, sotorasib, in xenograft models with MTAP deletion and a KRAS G12C mutation.

Financial Results

As of March 31, 2022, the Company held $449.9 million in cash, cash equivalents and marketable securities, which the company believes to be sufficient to fund operations into the second half of 2024.

Collaboration revenue was $5.8 million for the three months ended March 31, 2022, compared to $6.4 million for the same period in 2021. The decrease was due to lower research costs incurred under the Gilead collaboration during the three months ended March 31, 2022 resulting in lower collaboration revenue recognition.

Research and development expenses were $24.3 million for the three months ended March 31, 2022, compared to $15.0 million for the same period in 2021. The change was primarily due to increased expenses relating to the advancement of the programs and personnel-related costs.

General and administrative expenses were $6.8 million for the three months ended March 31, 2022, compared to $3.5 million for the same period in 2021. The change was primarily due to increases in personnel-related costs.

Net loss for the three months ended March 31, 2022 was $25.2 million, or $0.29 per share, compared to a net loss of $12.1 million, or $0.29 per share, in the same period in 2021.
