TxCell appoints MaSTherCell for the manufacturing of lead product Ovasave(R) from Q2 2016
Valbonne, France, July 29, 2015 – TxCell SA (Euronext Paris: FR0010127662 – TXCL), a biotechnology company developing innovative, personalized T cellimmunotherapies using antigen specific regulatory T-cells (Ag-Tregs) for severe chronic inflammatory and autoimmune diseases, announces today that it has entered into an agreement for the production of clinical batches of Ovasave(R) with MaSTherCell, a Contract Manufacturing Organization (CMO), based in Belgium.
The contract signed between TxCell and MaSTherCell is a Memorandum of Understanding for the manufacturing by MaSTherCell of clinical batches of TxCell's Ovasave. These Ovasave batches will be used by TxCell in the ongoing phase IIb trial with the product in refractory Crohn's disease patients (CATS29 study). The transfer of technology will start immediately. It is intended that first clinical batches could be manufactured as soon as Q2 2016.
In addition, TxCell is currently taking action at its existing pilot Besançon manufacturing unit in order to ensure future compliance with Good Manufacturing Practice (GMP) and recommence full manufacturing activities following a partial, temporary hold at the site. TxCell will then file to reobtain its GMP certificate as production will resume after the GMP certificate is granted back by the French regulator ANSM.
Ovasave clinical batches for the CATS29 study will be manufactured in parallel by MaSTherCell and TxCell's own facility. As previously disclosed, the Company expects to deliver top-line data from this study in 2017.
"This strategic relationship with MaSTherCell, a European leader in cellular therapy products manufacturing with a significant track record in production of clinical materials, is very important to TxCell," said Stéphane Boissel, Chief Executive Officer of TxCell. "We have immediately taken the appropriate actions at our manufacturing site in Besançon and the agreement with MaSTherCell should enable us to rapidly increase the efficiency of our manufacturing. This should both speed up enrollment in CATS29 and accelerate development on other products."
As part of the Memorandum of Understanding with MaSTherCell, TxCell and MaSTherCell also agree to enter into discussion for the long-term clinical and commercial manufacturing by MaSTherCell of Ovasave and other TxCellproducts. These discussions will take place in Q4 2015.
The CATS29 study is a multi-center, randomized, double-blinded, placebo-controlled, multi-dose and multi-injection, 4 parallel groups study. The study is conducted in 30 study sites in 6 countries (Austria, Belgium, France, Germany, Italy and United Kingdom). This study may now be extended to include US sites. The trial has been designed to include 160 severe refractory Crohn's disease patients. The primary objective of the CATS29 study is the evaluation of the response rate for a single intravenous injection of 10e6 cells dose of Ovasave(R) (ovalbumin-specific autologous Treg cells (Ova-Treg)) compared to placebo 6 weeks post administration. Response is defined as a decrease greater than or equal to 100 points in the Crohn's Disease Activity Index (CDAI), the gold standard regulatory measure of response in Crohn's disease. Patients will receive, double-blinded, two intravenous (iv) injections 8 weeks apart of either 10e4, 10e6, or 10e7 cells of Ovasave or placebo. Patients will then receive either an open-label treatment with 2 additional iv injections of 10e6 cells of Ovasave or a safety follow-up with no injection. Finally, there will be an extended safety follow-up for all patients.
