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 is listed with 2 APIs on the APIs.io network. Tagged areas include Company, Biotechnology, Biopharmaceutical, RNA Therapeutics, and siRNA.

The ADARx Pharmaceuticals catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

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.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

Access Clarity scores 21.1 — up to +15.8 composite points
Developer Ergonomics scores 23.2 — up to +15.4 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/adarx-pharmaceuticals/apis.yml: open an issue on github.com/api-evangelist/adarx-pharmaceuticals to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Clinical Trial Sponsors (drug pipelines)	standard	34.5 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
