Dren Bio
Dren Bio is a clinical-stage biopharmaceutical company based in Foster City, California, focused on the discovery and development of novel antibody therapeutics that selectively deplete pathogenic cells and other disease-causing agents. Its proprietary Targeted Myeloid Engager and Phagocytosis Platform is a multispecific, antibody-based technology designed to induce potent depletion of disease-causing agents by engaging a novel phagocytic receptor selectively expressed on myeloid cells. The pipeline spans two first-in-class clinical-stage programs (including DR-01 and DR-0202) plus multiple preclinical and discovery-stage programs across oncology, autoimmune disease, immunology, and neurology. Dren Bio has established strategic collaborations with Pfizer and Sanofi, the latter of which acquired its DR-0201 (SAR448501) bispecific myeloid cell engager program. The company was surfaced as a portfolio company of 8vc and added to the API Evangelist network. It publishes no public API or developer surface; this profile captures its identity and public web properties.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Dren Bio the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Dren Bio scores 12.3/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.
