TxCell is developing innovative, personalized T cell immunotherapies using antigen specific regulatory T-cells (Ag-Tregs) for severe chronic inflammatory and autoimmune diseases.

TxCell's strategy is to target niche and orphan indications for which there are few or no treatment options.


The product candidates developed by TxCell consist of autologous antigen-specific type 1 regulatory T cells (Ag-Tregs) generated ex-vivo from patient's blood in a proprietary manufacturing process (link).

Ovasave® is TxCell lead product candidate. A phase IIb placebo controlled study has been initiated in refractory Crohn's Disease patients. This follows a phase I/IIa study in the same patient population, which has been successfully completed and reported positive clinical efficacy and good tolerability (link1) (link2).


Txcell second product candidate, Col-Treg, is in development for Autoimmune Uveitis, a rare disease with very limited treatment options. The next step in this program will be a phase I/II proof of principle clinical trial.

Further product candidates for autoimmune inflammatory indications are in preclinical development.
