ADARx Pharmaceuticals

ADARx Pharmaceuticals, Inc. is a clinical-stage biotechnology company headquartered at 5871 Oberlin Drive, San Diego, California, founded in 2019 and developing next-generation RNA therapeutics intended to control the expression of specific disease drivers with highly selective RNA-targeted medicines. Its proprietary platform spans RNA interference, RNA editing and targeted oligonucleotide delivery, engineered around compact, modular constructs the company says extend reach beyond the liver. The clinical pipeline is led by ADX-324 (onvuzosiran), an siRNA against prekallikrein now in the Phase 3 STOP-HAE study in hereditary angioedema, and ADX-038 (agazisiran), an siRNA against complement factor B in Phase 2 for IgA nephropathy and C3 glomerulopathy, geographic atrophy and paroxysmal nocturnal hemoglobinuria; earlier programmes include ADX-626 (factor XI, thrombosis), ADX-077 (obesity) and ADX-199 (amyloid-beta precursor protein, neurodegeneration), plus undisclosed extrahepatic CNS, immunology and oncology work. The company closed an oversubscribed 200 million dollar Series C in August 2023 co-led by Bain Capital Life Sciences and TCGX, and entered a collaboration and license option agreement with AbbVie in May 2025. ADARx runs no developer program and publishes no product API, no developer portal and no API documentation; the only machine-readable surfaces reachable without credentials are the WordPress REST content APIs behind www.adarx.com and stophae.com, both catalogued here.

ADARx Pharmaceuticals publishes 8 APIs on the APIs.io network, including Clinics API, Content API, Embed API, and 5 more. Tagged areas include Company, biotechnology, biopharmaceuticals, rna-therapeutics, and sirna.

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/adarx-pharmaceuticals: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
