Latigo Bio

Latigo Biotherapeutics, Inc. ("Latigo Bio") is a clinical-stage biotechnology company headquartered in Thousand Oaks, California, developing novel non-opioid medicines for acute and chronic pain. Its lead candidates LTG-001 and LTG-321 are oral NaV1.8 sodium-channel inhibitors targeting pain at its peripheral source without the addiction risk of opioids; LTG-001 holds FDA Fast Track designation and reported positive Phase 2b results in post-abdominoplasty acute pain, published in the New England Journal of Medicine in July 2026. The company was founded on human-genetics-validated targets and uses in-house AI/ML and structure-based drug design to optimize potency and selectivity. It debuted in 2024 with a $135M Series A and closed a $150M Series B in March 2025, backed by Westlake Village BioPartners, 5AM Ventures, Foresite Capital and Corner Ventures. Latigo is a therapeutics developer, not a software vendor: it publishes no public API, developer portal, SDK or machine-readable specification.

Latigo Bio 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/latigo-bio: open an issue to ask a question, or submit a pull request to add artifacts.
