GeneFab

GeneFab is a California-based cell & gene therapy contract development and manufacturing organization (CDMO), built at the intersection of genetic design and clinical manufacturing. We partner with innovators globally to design, manufacture, and scale advanced therapies; from synthetic biology research and cell-specific promoters in South San Francisco to viral vector and cell therapy production for clinical support in Alameda, all under one roof. Modality-agnostic by design, we support the full breadth of the field — CAR-T, TCR-T, and γδ-T cells, NK and CAR-NK cells, regulatory T cells (Tregs), TILs and B cells, iPSCs and iPSC-derived cells, HSCs and CD34+ cells, mesenchymal stromal cells, and macrophages — alongside the lentiviral and gamma-retroviral vectors that engineer them. Our integrated capabilities span Analytical Development, Process Development, in-house Testing, Cell Banking, cGMP Manufacturing, Technology Transfer, and Fill/Finish — taking programs from construct to clinical supply without the friction of repeated tech transfer.

For CIRM grantees, GeneFab offers a manufacturing partner that keeps your program in-state, supporting the requirement that CIRM-funded work be performed in California and counting toward your California-supplier commitments — without compromising on scale, speed, or quality.
