Rexgenero expands manufacturing of REX-001 cell-based CLI therapy


Rexgenero, a regenerative medicine company developing advanced cell-based therapies to treat critical limb ischaemia (CLI), has announced that it has successfully expanded manufacturing of its lead development candidate REX-001 through a partnership with the German Red Cross Blood Donor Service in Frankfurt, Germany, signed earlier this year.

REX-001 is an autologous cell-based therapy and is manufactured using the patient’s own bone marrow. It contains immune cells (lymphocytes, monocytes and granulocytes) and progenitor cells involved in immune modulation and tissue regeneration. Manufacturing is time critical as it is important to ensure administration of the fresh product within 48 hours. Successfully transferring the manufacturing technology to this second GMP facility in Europe is a key milestone to ensure sufficient supply to patients enrolled in Rexgenero’s European Phase III SALAMANDER trials of REX-001 for the treatment of CLI in patients with diabetes.

REX-001 is already manufactured at Rexgenero’s own GMP manufacturing facility in Seville, Spain and used predominantly at clinical trial sites in Spain and Portugal. Under a manufacturing partnership, the German Red Cross Blood Donor Service will manufacture REX-001, principally for use at additional trial sites in Germany, Poland, Czech Republic, Hungary, The Netherlands, the UK and Austria. However, both sites are able to manufacture and deliver product for most clinical sites within the limited time frame, ensuring manufacturing flexibility and backup possibilities.

The German Red Cross Blood Donor Service is one of the largest blood donor services in Europe and has significant expertise in GMP manufacturing of cell-based investigational medicinal products. The manufacture of REX-001 is overseen by Halvard Bönig, Institute for Transfusion Medicine and Immunohematology, Goethe-University and German Red Cross Blood Service Baden-Württemberg-Hessen, Frankfurt am Main, Germany.

Edwin Wagena, COO of Rexgenero commented, “I would like to congratulate Professor Halvard Bönig and his team at the German Red Cross Blood Donor Service for successfully manufacturing REX-001 in Germany. This new manufacturing site complements the activities of our own facility in Spain and enables us to reduce delivery time to clinical trial sites across Central and Eastern Europe.”

Liesbeth de Jong, vice president, Manufacturing and Research & Development of Rexgenero added, “Successfully transferring the manufacturing technology for REX-001 to the German Red Cross Blood Donor Service confirms we have full control over all aspects of the manufacturing process. Manufacturing REX-001 involves a lot of technical expertise and know-how so it is excellent news that Professor Bönig and his team can now also manufacture REX-001. This will significantly increase the capacity and flexibility of product supply in our Phase III program.”

REX-001 Phase III SALAMANDER clinical trials are open and recruiting patients at sites in Spain, Austria, Portugal, Poland, the Czech Republic, Hungary and The Netherlands.
