Arkuda Therapeutics

Arkuda Therapeutics, Inc. was a privately held, preclinical-stage biotechnology company based in Watertown, Massachusetts, founded in 2018 by Gerhard Koenig, Ph.D. and Duane Burnett to develop small-molecule enhancers of lysosomal function for neurodegenerative disease. Its lead biology targeted progranulin (GRN) and lysosomal dysfunction in frontotemporal dementia (FTD-GRN), Alzheimer's disease and Parkinson's disease. Arkuda closed a $44M Series A in November 2019 and a $64M Series B in February 2022, backed by Atlas Venture, Cormorant Asset Management, Pfizer Ventures, abrdn plc, Mission BioCapital and Eli Lilly and Company. On 27 February 2024 it entered an option and asset purchase agreement with Johnson & Johnson, and on 9 January 2025 Johnson & Johnson (through Janssen Pharmaceuticals) exercised that option and acquired the entire portfolio of lysosomal function enhancers. Independent operations concluded thereafter; founder and CEO Gerhard Koenig became CEO of Augustine Therapeutics in January 2025. Arkuda was a therapeutics developer, not a software company: it never operated a developer program, public API, SDK or machine-readable API contract, and both of its former domains have since lapsed.

Arkuda Therapeutics is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Life Sciences, and Drug Discovery.

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/arkuda-therapeutics: open an issue to ask a question, or submit a pull request to add artifacts.
