Tango Therapeutics works on medicines aimed at treating cancer, built around the idea of exploiting genetic weaknesses found in tumor cells. Its furthest-along candidate, TNG908, is a small molecule designed to block PRMT5, a protein enzyme, and is being studied as a treatment for cancers that carry MTAP gene deletions. The company is best known for this synthetic lethal approach, where a drug is matched to a specific genetic flaw in the cancer.
Beyond its lead program, Tango Therapeutics is developing a USP1 inhibitor meant for cancers with BRCA1 or BRCA2 mutations, along with an earlier-stage effort called Target 3 directed at STK11-mutant cancers. The company has a partnership with Gilead Sciences, Inc. through which the two work together on finding, developing, and bringing to market a range of cancer treatments.
Tango Therapeutics was founded in 2017 and is based in Cambridge, Massachusetts. Its shares are listed on the NASDAQ under the ticker TNGX.
