ADMIRE Study: Use of Stem Cell Therapy for Complex Perianal Fistulas in Crohn’s Disease

A recent phase 3 randomized, double-blind, placebo-controlled study (J Panes et al. Gastroenterol 2018; 154: 1334-42) examined the use of stem cell therapy for the treatment of complex perianal fistulas in Crohn’s disease (CD).

They used a single local injection of 120 million Cx601, a suspension of allogeneic expanded adipose-derived stem cells, and compared to a placebo injection.  This study comprised 212 patients from 49 centers. The primary endpoint, labelled “combined remission,” was based on absence of draining fistulas and MRI findings.

Key Findings:

  • As noted in Figure 1 (below), combined remission occurred in 51.5% of Cx601-Rx patients compared with 35.6% for placebo at week 24; at week 52, combined remission occurred in 56.3% of Cx601-Rx patients compared with 38.6%

My take: This local therapy improved outcomes for 1 year after a single injection and appears promising for refractory perianal fistulas.  It may help avoid surgery or systemic immunosuppression.
