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.

Dren Bio is profiled on the APIs.io network. Tagged areas include Company, Biopharmaceutical, Biotechnology, Antibody Therapeutics, and Oncology.

Dren Bio’s developer surface includes support, engineering blog, and 4 more developer resources.

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.

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