Syntis Bio

Syntis Bio is a clinical-stage biopharmaceutical company in Boston, Massachusetts developing oral therapies that use the small intestine as a delivery site. Its SYNT platform (Synthetic Tissue-lining) applies a mussel-inspired polydopamine polymer coating transiently to specific tissues in the GI tract, sustaining therapeutic activity for up to 24 hours before being naturally cleared. The platform is being applied to nutrient exclusion for obesity, gut-restricted enzyme replacement for rare metabolic disorders such as homocystinuria and maple syrup urine disease, and oral bioavailability enhancement for peptides and biologics. Lead candidate SYNT-101 is a once-daily oral pill intended to mimic aspects of gastric bypass by transiently blocking nutrient absorption in the duodenum. The company was co-founded in 2022 by MIT's Robert Langer and Giovanni Traverso with CEO Rahul Dhanda. Syntis Bio is a therapeutics developer and publishes no public API, developer program, SDK, or machine-readable specification.

Syntis Bio is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Pharmaceuticals, Life Sciences, and Drug Delivery.

Syntis Bio’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.

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