DC3 Therapeutics

DC3 Therapeutics is a private, active contract research organization based in South San Francisco that supports biotech and pharmaceutical clients across discovery, preclinical, IND-enabling, and selected clinical-stage laboratory activities. The company positions itself as a one-stop CRO offering cell and molecular biology, biochemical and cell-based assays, protein chemistry, histology, immunohistochemistry, spatial biology, biomarker analysis, and program management services. DC3 also operates a CLIA-certified, COLA-accredited laboratory and provides companion diagnostic support and custom lab-developed tests. Rather than advancing a proprietary therapeutic pipeline, the company provides integrated scientific services intended to accelerate client decision-making and regulatory readiness. Its business model is service-based and collaborative, acting as an extension of internal R&D teams for drug discovery and early development programs.
