Cour Pharmaceuticals Development

COUR Pharmaceuticals Development Co., Inc. (COUR Pharma) is a privately held, clinical-stage biotechnology company founded in 2012 and headquartered in the Chicago area (Northbrook/Skokie, Illinois), spun out of research at Northwestern University. COUR develops antigen-specific immune tolerance therapies built on its proprietary COUR Nanoparticle (CNP) platform: biodegradable polymer nanoparticles of roughly 500 nm carrying about 1% disease-specific antigen, which mimic apoptotic bodies so that antigen-presenting cells in the liver and spleen re-recognize the antigen as self, deleting pathogenic T cells and expanding regulatory T cells. Active clinical programs include CNP-103 for Type 1 Diabetes and CNP-106 for Myasthenia Gravis, with earlier work in Primary Biliary Cholangitis and Celiac Disease. COUR is a therapeutics developer, not a software or platform company: it publishes no developer program, no public API, and no machine-readable API contract of any kind.

Cour Pharmaceuticals Development is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Life Sciences, and Immunology.

Cour Pharmaceuticals Development’s developer surface includes engineering blog and 10 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.

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/.

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/cour-pharmaceuticals-development: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: COUR Pharma is a clinical-stage biotech developing CNP nanoparticle immune-tolerance therapies; its entire public
    site is a WordPress marketing/investor site with no developer section, api./developer./docs.courpharma.com do not resolve
    in DNS, and every contract and /.well-known/ probe returned the site's HTML 404 — the only machine-readable endpoint on
    the host is stock WordPress /wp-json/ CMS plumbing (Elementor, Astra, Forminator), not a product API.
