Allay Therapeutics

Allay Therapeutics is a clinical-stage biopharmaceutical company with operations in San Jose, California and Singapore, developing ultra-sustained, non-opioid analgesic products for post-surgical pain management. Its platform is a tunable drug-biopolymer architecture that pairs validated non-opioid analgesics with dissolvable biopolymers to release pain relief at a targeted surgical site over weeks rather than days, and can be tuned for constant release (chronic pain such as osteoarthritis) or pulsed release (cyclic pain such as gout). Lead candidate ATX-101 is a bupivacaine-based implant placed directly at the surgical site during total knee replacement (TKA), targeting the three-day to two-week analgesia gap that drives breakthrough pain and opioid use; it holds FDA Breakthrough Therapy Designation and entered a pivotal Phase 2b registration trial with first patients dosed in 2025. Additional programs (ATX-201, ATX-301, ATX-401, ATX-501) span new formulations, injectables, additional clinical indications and on-demand anesthetic delivery. The company raised a $57.5M Series D plus a venture debt line in 2025 and has a development and commercialization agreement with Maruishi Pharmaceutical for Japan. It is a therapeutics developer, not a software company, and publishes no developer program, API, SDK, or machine-readable interface.

Allay Therapeutics publishes 8 APIs on the APIs.io network, including Comments API, Discovery API, Media API, and 5 more. Tagged areas include Company, Biotechnology, Pharmaceuticals, Pain Management, and Drug Delivery.

Allay Therapeutics’ developer surface includes product news, authentication, and 22 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/. 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/allay-therapeutics: open an issue to ask a question, or submit a pull request to add artifacts.
