KSQ Therapeutics

KSQ Therapeutics is a clinical-stage biotechnology company headquartered at 4 Maguire Road in Lexington, Massachusetts, founded in 2015 by pioneers of CRISPR screening and functional genomics. Its proprietary CRISPRomics platform runs genome-scale CRISPR/Cas9 functional genomic screens across cancer models and immune cell types to identify therapeutic targets that directly correlate genomic function to disease. The company applies those targets in two directions: CRISPR/Cas9-engineered tumor-infiltrating lymphocyte (eTIL) cell therapies, where a single gene is inactivated to increase the tumor-killing capacity of a patient's own T cells — KSQ-001EX (SOCS1 inactivated) and KSQ-004EX (SOCS1 and Regnase-1 inactivated) — and small molecules such as KSQ-4279, a first-in-class USP1 inhibitor for advanced solid tumors. KSQ has run broad discovery collaborations with Takeda, licensed cell-therapy technology with CRISPR Therapeutics, partnered manufacturing with CTMC, and sold multiple research-stage oncology programs to Ono Pharmaceutical. Investors include Flagship Pioneering, ARCH Venture Partners, Polaris Partners, Alexandria, Alpha Wave Global, Baillie Gifford, Invus, LG and Lilly Asia Ventures. KSQ Therapeutics runs no developer program and publishes no product API, developer portal, OpenAPI or API reference. The only machine-readable surfaces reachable without credentials are the WordPress REST content API behind ksqtx.com, an All in One SEO generated /llms.txt, and the open-source bioinformatics code in its public GitHub organization — all catalogued here.

KSQ Therapeutics publishes 8 APIs on the APIs.io network, including Press Releases API, Pages API, Media API, and 5 more. Tagged areas include Company, Biotechnology, Life Sciences, Therapeutics, and Oncology.

KSQ Therapeutics’ developer surface includes engineering blog, product news, support, authentication, CLI, and 25 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/. This rating is computed from github.com/api-evangelist/ksq-therapeutics: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
