Abdera Therapeutics

Abdera Therapeutics is a clinical-stage biopharmaceutical company headquartered in South San Francisco, California, with research operations in Vancouver, British Columbia. It was launched in 2021 out of adMare BioInnovations with AbCellera as a founding partner and has raised roughly $148 million from investors including Versant Ventures, Foresite Capital, Johnson & Johnson Innovation (JJDC), Qiming Venture Partners USA, RTW Investments and venBio. The company engineers precision radiopharmaceuticals for solid tumours on its proprietary Radio Optimized Vector Engineering (ROVEr) platform, which pairs antibody-derived targeting vectors with potent alpha-emitting radioisotopes such as actinium-225. Its lead candidate, ABD-147, targets delta-like ligand 3 (DLL3) and is in a Phase 1 trial (NCT06736418) in small cell lung cancer and large cell neuroendocrine carcinoma under FDA Fast Track designation; a second program, ABD-320, targets 5T4. Abdera's product is a drug candidate, not software. It runs no developer program and publishes no API, developer portal, API reference, SDK, or machine-readable specification of any kind. As of 2026-09-06 the company's own corporate site at www.abderatx.com was additionally unreachable, returning a Flywheel "Unknown Domain" host error on every path behind a TLS certificate that expired on 2026-07-19.

Abdera Therapeutics is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Radiopharmaceuticals, 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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/abderatherapeutics: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Abdera Therapeutics is a clinical-stage radiopharmaceutical developer whose product is a drug candidate (ABD-147,
    ABD-320), not software — there is no developer program to profile, and the point is moot in any case because its entire
    corporate site at www.abderatx.com now returns a Flywheel "Unknown Domain" 404 on every path, including the root, behind
    a TLS certificate that expired on 2026-07-19.
