Carbylan Therapeutics Completes Enrollment of Phase 3 Pivotal Trial for Hydros-TA

PALO ALTO, Calif., June 8, 2015 (GLOBE NEWSWIRE) -- Carbylan Therapeutics (Nasdaq:CBYL), a specialty pharmaceutical company focused on the development of novel and proprietary combination therapies, today announced that it has completed enrollment of its 510 subject COR1.1 Phase 3 pivotal trial of Hydros-TA for the treatment of pain associated with osteoarthritis. Subjects were enrolled at 30 clinical sites in Canada, Australia, New Zealand, The Netherlands, Hungary and Curacao.

COR1.1 is the first of two pivotal trials of Hydros-TA as part of Carbylan's Phase 3 program design. The trial is comprised of subjects with Kellgren-Lawrence Grade 2 and 3 osteoarthritis (OA) of the knee. Subjects were randomized equally between three treatment arms: Hydros-TA, Hydros and TA (Triamcinolone Acetonide). The objective of the trial is to demonstrate the safety and efficacy of Hydros-TA and the contribution of each of the two components in this therapy. The primary endpoints are the change from baseline in WOMAC A (pain) subscale scores for Hydros-TA versus Hydros at two weeks and Hydros-TA versus TA at 26 weeks. Secondary endpoints include WOMAC C (function) changes, subject and physician global assessment changes and OMERACT_OARSI responder analysis. The Company expects top-line data from this trial in early 2016.

David Renzi, President and CEO of Carbylan Therapeutics, commented, "The completion of COR1.1 subject enrollment is a significant milestone for Carbylan and an important step toward our goal of bringing Hydros-TA to market. We believe this product can provide a potentially best in class alternative to the treatment options currently available for patients suffering from the pain of osteoarthritis by utilizing our proprietary crosslinking technology to combine a low dose steroid with our novel hyaluronan in order to offer both rapid and sustained pain relief."
