Expanded Access Protocol for STOMP-II Patients Who Were Unable to Receive Treatment Subsequent to Adipose Tissue Collection

AVB-114 is a mesenchymal cell substrate system comprised of autologous mesenchymal cells incubated with a 3-dimensional bioabsorbable substrate. The drug substance is expanded, pure mesenchymal stem cells (MSC) which are known to modulate local inflammation and orchestrate tissue healing. By incubating cells with a 3-dimensional bioabsorbable substrate designed for anal fistula geometry, cells are locally delivered into the fistula tract to promote healing.
