GRIN Therapeutics

GRIN Therapeutics, Inc. is a clinical-stage biotechnology company dedicated to the research and development of precision therapeutics for pediatric neurodevelopmental disorders caused by NMDA receptor dysfunction. It is an affiliate of Neurvati Neurosciences, a Blackstone Life Sciences portfolio company, and traces its founding to Dr. Pierandrea Muglia's attendance at the 2019 CFERV Conference on GRIN Variants at Emory University. Its lead investigational asset is radiprodil, an orally bioavailable selective negative allosteric modulator of the GluN2B subunit of the NMDA receptor, designed to fine-tune dysregulated receptor activity rather than fully block the channel. Radiprodil is in development for GRIN-related neurodevelopmental disorder (GRIN-NDD) arising from gain-of-function variants in GRIN1, GRIN2A, GRIN2B and GRIN2D, and for tuberous sclerosis complex (TSC) and focal cortical dysplasia (FCD) type II. The clinical programme comprises the completed Phase 1b/2a Honeycomb trial, the enrolling global Phase 3 Beeline registrational trial, the Phase 1b/2a Astroscape trial in TSC and FCD type II, and a GRIN-NDD natural history study; radiprodil carries FDA Breakthrough Therapy, Orphan Drug and Rare Pediatric Disease designations and EMA PRIME and Orphan Drug designations. In May 2025 GRIN Therapeutics entered an exclusive collaboration with Angelini Pharma to develop and commercialise radiprodil outside North America. GRIN Therapeutics runs no developer program and publishes no product API, no developer portal and no API documentation; the only machine-readable surface reachable without credentials is the WordPress REST content API behind grintherapeutics.com, catalogued here.

GRIN Therapeutics publishes 8 APIs on the APIs.io network, including Discovery API, Media API, Oembed API, and 5 more. Tagged areas include Company, Biotechnology, Pharmaceuticals, Neuroscience, and Rare Disease.

GRIN Therapeutics’ developer surface includes product news, support, authentication, and 24 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/grin-therapeutics: open an issue to ask a question, or submit a pull request to add artifacts.
