Be Biopharma (Be Bio) is a Cambridge, Massachusetts clinical-stage biotechnology company founded in October 2020 by Longwood Fund together with B cell engineering researchers David Rawlings, M.D. and Richard James, Ph.D. of Seattle Children's Research Institute. The company develops engineered B Cell Medicines (BCMs) — a patient's own B cells engineered to produce a therapeutic protein — for genetic disease, cancer and other serious conditions. Its lead candidate, BE-101, inserted a functional Factor IX gene into primary human B cells for hemophilia B and held FDA Orphan Drug and Fast Track designations; a second program, BE-102, targeted hypophosphatasia. The company raised $82M in October 2024 and $92M in a January 2025 Series C, dosed the first participant in the Phase 1/2 BeCoMe-9 trial in July 2025, and terminated that trial in June 2026 for stated strategic business reasons. Be Biopharma is a therapeutics developer, not a software company: it has never published a developer program, API, SDK or machine-readable contract.
Be Biopharma is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Life Sciences, Cell Therapy, and Gene Therapy.
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/.

Agent readiness — checks not met, largest first (exact, from this profile):
Machine-Readable Auth+10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
13 more unmet checks in the Agent Readiness table above.

detail: Be Biopharma's own domain be.bio no longer resolves — its authoritative nameservers (ns1.g02.cfdns.net) return SOA
only for both the apex and www, so there is no host left to probe; the site was last archived 2026-05-13, the company
terminated its lead BeCoMe-9 hemophilia B trial in June 2026, and LinkedIn now lists a single employee.
