Purdue Pharma L.P. and Ocular Therapeutix, Inc. announced the initiation of research activities leading to a strategic research collaboration. The goal is to determine compatibility of Purdue’s non-opioid new chemical entities with Ocular’s bioresorbable hydrogel-based technology, ideally leading to the development of new products for the treatment of pain. Ocular Therapeutix will initiate formulation testing, with the goal of bringing it to a stage where efficacy can be assessed.
