Vascular Therapies

Vascular Therapies, Inc. is a privately held, clinical-stage biopharmaceutical company headquartered in Cresskill, New Jersey, developing Sirogen, a proprietary sirolimus formulation delivered from a bioabsorbable collagen implant placed perivascularly at the time of surgery. The product is aimed at reducing surgical stenosis and improving arteriovenous fistula maturation and patency in end-stage renal disease patients who need hemodialysis vascular access. Sirolimus for dialysis vascular access carries FDA Fast Track status and Orphan Drug designation in both the United States and the European Union. The company ran the Phase 3 ACCESS trial (243 ESRD patients across 20 US sites) and the multinational Phase 3 ACCESS 2 trial, whose topline results presented in April 2025 did not meet the primary clinical fistula maturation endpoint. Vascular Therapies is a therapeutics developer, not a software company: it ships a drug-device combination product through clinical trials and regulatory review, and publishes no API, SDK, developer portal or machine-readable contract of any kind.

Vascular Therapies is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Medical Devices, and Drug Delivery.

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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
