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.
