Scorpion Therapeutics

Scorpion Therapeutics is a clinical-stage precision oncology biotechnology company founded in 2020 and headquartered in Boston, Massachusetts. It pursued what it called Precision Oncology 2.0 — integrating target discovery, medicinal chemistry and translational medicine to produce mutant-selective small-molecule cancer drugs — led by STX-478, an oral mutant-selective PI3K-alpha inhibitor in Phase 1/2 trials for breast cancer and other advanced solid tumors, and STX-721, a covalent EGFR/HER2 exon 20 inhibitor. In January 2025 Eli Lilly agreed to acquire Scorpion and its PI3K-alpha program in a transaction valued at up to $2.5 billion, with the non-PI3K-alpha pipeline and staff spun into a separate independent company. Scorpion is a drug developer, not a software vendor: it publishes no API, SDK, developer portal or machine-readable specification, and its own domain now redirects to the acquirer's announcement.

Scorpion Therapeutics is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Oncology, and Precision Medicine.

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/.

  detail: Scorpion's own site no longer serves the company — https://www.scorpiontx.com/ 302-redirects every request to Eli
    Lilly's January 2025 acquisition press release, and the only first-party technical surface left is a four-repo GitHub
    org of computational-chemistry forks and an STX-721 molecular-dynamics data-availability README, with no API, SDK or spec
    anywhere.
