Predictive modeling to evaluate long-term treatment effectiveness of darvadstrocel in patients with complex perianal fistulas in Crohn's disease.

Background: Current therapies for complex Crohn's perianal fistulas (CPF) have a limited ability to achieve long-term healing. Darvadstrocel (DVS) is an expanded allogeneic adipose-derived mesenchymal stem cell therapy that has demonstrated efficacy in treating complex CPF in clinical trials. There are, however, limited long-term comparative data with standard of care (SoC).

An assessment of the hospital exemption landscape across European Member States: regulatory frameworks, use and impact.

The hospital exemption (HE) (Article 28(2) of Regulation (EC) No 1394/2007; the "ATMP Regulation") rule allows the invaluable opportunity to provide patients with access to innovative, potentially life-saving treatments in situations of unmet clinical need. Unlicensed, developmental advanced therapy medicinal products (ATMPs) - cell-, gene- or tissue-based therapies - can be used to treat patients under certain conditions. Such products should be produced on a non-routine basis, custom-made for an individual patient under the responsibility of the requesting physician, for use in a hospital setting within the same Member State in which they are manufactured.
