Pathalys Pharma

Pathalys Pharma, Inc. is a private, late-stage clinical biopharmaceutical company headquartered at 4000 Center at North Hills Street, Raleigh, North Carolina, in the Research Triangle Park region. It was created with initial funding from Catalys Pacific and the DaVita Venture Group to be a multi-asset biopharmaceutical company focused on the needs of patients with end-stage kidney disease, and it develops advanced therapeutics addressing unmet needs in the management of late-stage chronic kidney disease (CKD). Its lead asset is upacicalcet, a novel non-peptide calcimimetic delivered intravenously by pre-filled syringe at the end of a hemodialysis session for the treatment of secondary hyperparathyroidism (SHPT) in patients with end-stage kidney disease on hemodialysis; it is an investigational product candidate in the United States, subject to FDA review. Pathalys raised $150 million in secured product financing and equity led by Abingworth in January 2023 alongside a development collaboration with Launch Therapeutics to run the pivotal PATH Phase 3 program, and closed an oversubscribed $105 million Series B in August 2024 to fund NDA submission and pre-commercialization. Pathalys runs no developer program and publishes no product API; the only machine-readable surface it exposes is the anonymously readable WordPress REST content API behind pathalys.com, which serves the corporate site, the news and scientific-updates stream, and the media library.

Pathalys Pharma publishes 7 APIs on the APIs.io network, including Posts API, Pages API, Media API, and 4 more. Tagged areas include Company, Pharmaceuticals, Biotechnology, Nephrology, and Chronic Kidney Disease.

Pathalys Pharma’s developer surface includes product news, engineering blog, support, documentation, authentication, and 20 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/pathalys-pharma: open an issue to ask a question, or submit a pull request to add artifacts.
