Antares Therapeutics

Antares Therapeutics is a Boston- and South San Francisco-based precision medicine company developing small-molecule therapies against validated but previously undruggable targets in cancer and other serious diseases. Spun out of Scorpion Therapeutics following Eli Lilly's March 2025 acquisition of Scorpion, Antares launched in June 2025 with a $177 million Series A co-led by Omega Funds, Atlas Venture, Lightspeed Venture Partners, BVF Partners and Cormorant Asset Management. The company combines medicinal chemistry (proprietary compound libraries and next-generation mass spectrometry to find new chemical pockets), target biology (first-in-class preclinically validated targets and allosteric approaches to clinically validated ones), and predictive sciences (physics-based modeling, machine learning and molecular dynamics) to shorten discovery cycles. Its most advanced program is expected to enter the clinic in 2026, with multiple additional preclinical programs and discovery collaborations with Novartis, AstraZeneca and Pierre Fabre Laboratories. Antares is a private, preclinical-stage biotechnology company and publishes no public product API, developer portal or SDK surface.

Antares Therapeutics publishes 1 API on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Precision Medicine, and Oncology.

Antares Therapeutics’ developer surface includes engineering blog, product news, authentication, and 14 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/antares-therapeutics: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?

  description: The public WordPress REST API behind antaresrx.com. This is the content management surface for the corporate
    marketing site and its press-release / in-the-media newsroom -- it is NOT a first-party product API. Anonymous reads of
    published posts, pages, categories, media and tags are available under the wp/v2 namespace; all write operations and the
    site's MCP adapter route require authentication and return 401 to anonymous callers. Recorded here because it is a real,
    fetchable API surface on the company domain and it is what feeds the newsroom RSS pull.

  note: No product API, developer portal, SDK, sandbox, changelog or status page exists. An MCP endpoint was found on the
    domain but it is the WordPress MCP Adapter plugin and returns 401; it is deliberately NOT wired as type MCPServer. No
    first-party packages exist in any registry, and no vulnerability disclosure programme or trust center was verified, so
    no SDKs, Security or Compliance pointers are emitted.
