Quanta Therapeutics

Quanta Therapeutics is a privately held, clinical-stage biopharmaceutical company founded in 2018 and headquartered at 2 Tower Place in South San Francisco, California, with a second site in Radnor, Pennsylvania. It develops oral allosteric small-molecule medicines for RAS-driven cancers by targeting the protein-protein interactions that drive oncogenic RAS signaling, an approach the company describes as conformational blockade of RAS. Its discovery engine is a proprietary high-throughput Second Harmonic Generation (SHG) optical platform that detects subtle protein conformational changes and so surfaces allosteric modulators of signaling complexes that conventional binding assays miss. The clinical pipeline is a set of direct multi-KRAS inhibitors: QTX3034, a G12D-preferring oral multi-KRAS inhibitor in Phase 1 as monotherapy and in combination with cetuximab in KRAS G12D-mutant solid tumors; QTX3544, a G12V-preferring multi-KRAS inhibitor cleared for IND in January 2025; and QTX3046, which dosed its first patient in a Phase 1/1b trial in June 2024. Indications span pancreatic, colorectal, lung and endometrial cancers. The company announced a $60 million Series C in October 2021 and a Series D of over $50 million in May 2023 led by Avidity Partners alongside Sofinnova Investments, Vida Ventures, Surveyor Capital, Longitude Capital and AbbVie Ventures. Quanta Therapeutics runs no developer program and publishes no public API. Its corporate site is a single static HTML document served from Apache with anchor-based sections; probes for OpenAPI, GraphQL, MCP, llms.txt and every /.well-known/ discovery path returned HTTP 404, and no api./developer./docs. subdomain resolves.

Quanta Therapeutics is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Life Sciences, and Oncology.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/quanta-therapeutics: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
