TiGenix Potential Therapy for Crohn’s-related Perianal Fistulas Gets FDA Approval
The U.S. Food and Drug Administration (FDA) has granted TiGenix orphan drug designation for its lead candidate Cx601, which aims to treat perianal fistulas caused by Crohn’s disease in patients who have not improved with conventional treatments. About 10 to 15 percent of Crohn’s patients develop such fistulas. These are small abnormally formed channels that connect the area close to the anus and the outside skin area, causing constant, throbbing pain. Current treatments for this secondary manifestation of Crohn’s include antibiotics, immunosuppressants, anti-TNFs and surgery. However, none produce long-lasting benefits, and all have potentially severe complications and safety concerns. Cx601 is based on adipose-derived stem cells collected from a donor and previously expanded in a laboratory. Results of the European Phase 3 ADMIRE-CD clinical trial (NCT01541579) showed that a single dose of Cx601 could induce a long-term, sustained healing effect of complex perianal fistulas in Crohn’s patients. These benefits were further confirmed upon completion of 52 weeks and 104 weeks follow-up extension of the trial. Cx601 has received similar orphan drug designation by Swiss regulators as well as the European Commission. The positive ADMIRE-CD data has supported a Marketing Authorization Application to the European Medicines Agency (EMA), with expected initial evaluation by year's end. TiGenix is now conducting a global pivotal Phase 3 clinical trial (
