BioTheryX

BioTheryX is a private, clinical-stage biopharmaceutical company headquartered in San Diego, California, discovering and developing first-in-class targeted protein degraders — both bifunctional degraders and molecular glues — for cancer and inflammatory disease. Its proprietary PRODEGY platform is built on Cereblon-binding expertise carried over from founders who worked on FDA-approved Cereblon modulators. The lead program BTX-9341, a dual CDK4/CDK6 degrader, is in Phase 1 for HR+/HER2- breast cancer, alongside BTX-10908 targeting SOS1 for pan-KRAS mutant cancers and PDE4 degraders for inflammatory conditions; the company also partners with Incyte on molecular glue degrader discovery. BioTheryX is a therapeutics developer with no public developer program: probes on 2026-08-02 returned 404 for /openapi.json, /swagger.json, /api-docs, /llms.txt and every /.well-known/ discovery path on biotheryx.com, and there is no api./developer./docs./portal. subdomain, GitHub organization, or published SDK.

BioTheryX is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Life Sciences, and Drug Discovery.

BioTheryX’s developer surface includes engineering blog and 10 more developer resources.

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/biotheryx: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
