MBrace Therapeutics

MBrace Therapeutics is a privately held, clinical-stage biopharmaceutical company developing antibody-drug conjugates (ADCs) against novel oncology targets. Co-founded by Renata Pasqualini, Ph.D. and Isan Chen, MD, the company builds its pipeline on SPARTA, an in vivo antibody selection and target discovery process it uses to find ADC targets that conventional in vitro discovery misses. Its lead candidate MBRC-101 is an anti-EphA5 monomethyl auristatin E (MMAE) antibody-drug conjugate in a multi-centre, open-label Phase 1/1b dose-finding, safety and pharmacokinetic study in advanced refractory solid tumours; MBRC-201 is in Phase 2, MBRC-301 is in IND-enabling studies against solid tumours, and MBRC-401 is in discovery. MBrace emerged from stealth in November 2023 with an $85 million Series B led by TPG through TPG Life Sciences Innovations, alongside Avidity Partners, Blue Owl Capital, Venrock and Alta Partners, bringing total capital raised to $110 million. MBRC-101 was named Most Promising Clinical Candidate at the 11th Annual World ADC Awards. MBrace Therapeutics runs no developer program and publishes no product API, developer portal, API reference or SDK. The only machine-readable surface reachable without credentials is the WordPress REST content API behind mbracetrx.com, catalogued here — notable because the company registered five of its own custom post types, so its board, executive committee, founders, named investors and scientific advisory board are all published as structured JSON rather than only as rendered HTML.

MBrace Therapeutics publishes 9 APIs on the APIs.io network, including Discovery API, Media API, News API, and 6 more. Tagged areas include Company, Biotechnology, Pharmaceuticals, Oncology, and Antibody-Drug Conjugates.

MBrace Therapeutics’ developer surface includes product news, authentication, and 26 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/mbrace-therapeutics: open an issue to ask a question, or submit a pull request to add artifacts.
