Clinical trials

This is a multicentre, prospective, three-arm, parallel-group randomized controlled superiority trial evaluating fibrillar Type-I collagen haemostat (Hemocoll®) FTC, Avitene™ Microfibrillar Collagen Hemostat (MCH), and conventional bone wax for control of bleeding from exposed cancellous bone following planned single-ray amputation. Adults undergoing single-ray amputation involving a phalanx, metacarpal or metatarsal will be randomized in a 1:1:1 ratio. The primary comparison is Hemocoll® FTC versus Avitene™ MCH. Complete haemostasis is defined as VIBe Grade 0 sustained continuously for 60 seconds without rescue haemostasis at the prespecified anatomical assessment time: 2 minutes for phalanx, 3 minutes for metacarpal, and 5 minutes for metatarsal. Secondary comparisons include Hemocoll® FTC versus bone wax and Avitene™ MCH versus bone wax.

This is a randomized controlled clinical investigation in patients suffering from diabetic foot ulcers at multiple centres in India and Bangladesh. The study compares patient outcomes using standard wound care with a High Purity Type-I Collagen-Based Skin Substitute against standard wound care with an Acellular Intact Fish Skin Matrix.
