Darvadstrocel, sold under the brand name Alofisel, is a medication used to treat complex perianal fistulas in adults with non-active/mildly active luminal Crohn's disease when fistulas have shown an inadequate response to at least one conventional or biologic therapy.[1] It contains mesenchymal stem cells from fat tissue of adult donors.[2]

It was approved for use in the European Union in March 2018.[2] The approval was spearheaded by data published in the ADMIRE-CD trial.[2][3]

It was approved for use in Japan by Japan's Ministry of Health, Labour and Welfare (MHLW) in September 2021.[4]

Medical use

Darvadstrocel has been approved by the European Union for the treatment of adults with complex Crohn's perianal fistulas after conventional or biological medications have not worked.[2]

Mechanism of action

Darvadstrocel works by reducing inflammation and facilitating the growth of tissue in the fistula tract.[2][3]

History

ADMIRE-CD

The ADMIRE-CD trial was a phase III trial that assessed the safety and efficacy of darvadstrocel vs. placebo in adults with complex perianal fistulas with Crohn's disease.[3][5] The study randomized a total of 212 patients.[3] 107 patients were given darvadstrocel and 105 patients were given placebo.[3]

After one year, the study found darvadstrocel to be effective in closing external fistula openings, compared to placebo.[3] Patients taking darvadstrocel had a combined remission of 56.3% and clinical remission of 59.2%.[3] The placebo controls had a combined remission of 38.6% and clinical remission of 41.6%.[3]

INSPECT

Published in 2022, the INSPECT study is a retrospective study that evaluated the long-term effectiveness and safety of darvadstrocel in patients with perianal fistulas in Crohn's disease that were treated in the ADMIRE-CD trial.[6] The study data showed that darvadstrocel or the maintenance treatment used can have long term clinical remission in patients.[6]
