Cellex Cell Professionals Surpasses 10,000 Autologous ATMP Manufacturing Batches

COLOGNE, Germany, Oct. 6, 2026 /PRNewswire/ -- Cellex Cell Professionals has surpassed 10,000 autologous manufacturing batches for advanced therapy medicinal products (ATMPs), produced for 12 clinical and commercial partner programs. The milestone reflects Cellex's experience as a contract development and manufacturing organization (CDMO) specializing in personalized cell therapies.

In autologous cell therapy, every batch is made for one individual patient. Collection of starting material, manufacturing, quality control, logistics and chain-of-identity processes must be coordinated within tightly controlled, patient-specific workflows. The significance of the milestone therefore goes beyond volume: each batch represents a complete, patient-specific operation executed under strict control.

Cellex also knows these challenges from the developer's side. Its own CAR-T programs were contributed to the formation of AvenCell in 2021 to develop autologous and CRISPR/Cas-edited allogeneic CAR-T therapies. That experience gives Cellex direct insight into the scientific, regulatory and operational hurdles its partners face, and it shapes how the company refines its processes, quality systems and operating models.

"Every one of these 10,000 batches was made for one specific patient," said Dr. Suvi Annala, Vice President Manufacturing. "Behind each of them is a coordinated chain of collection, manufacturing, testing and logistics that has to work on a timeline that matters to someone waiting for treatment. What we learn from each partner program feeds directly into how we run the next one."

Cellex continues to invest in the capabilities needed for increasingly complex cell therapy programs including additional Grade B cleanrooms at its Cologne Ossendorf site. Building on this foundation, Cellex will keep working with its partners to deliver complex cell therapies reliably to patients at scale.
