What to evaluate for Cell Therapy programs
Both Merck KGaA / MilliporeSigma (CDMO) and WuXi Biologics qualify as Cell Therapy CDMOs. When choosing between them for Cell Therapy programs, weigh these four dimensions specifically — each carries through to the side-by-side scorecard above.
Autologous vs allogeneic
Autologous needs per-patient scheduling, chain-of-identity, and short turnaround; allogeneic needs scalable batch processing and a master cell bank strategy. Pick a CDMO proven in your model.
Vector & raw materials
Most cell therapies need a viral vector. Confirm whether the CDMO makes vector in-house or coordinates an external supplier, and how that affects timelines.
Closed-system & cleanrooms
Closed, automated processing reduces contamination risk and labor. Ask about cleanroom grade, automation platforms, and parallel-suite capacity.
Cold chain & logistics
Cryopreservation and chain-of-custody are critical for living cells. Evaluate the CDMO's cold-chain and apheresis-to-infusion logistics.
