The contest between the two main classes of antiproliferatives for circulatory system use continues as seen in a presentation at this year’s Transcatheter Cardiovascular Therapeutics.

The days when paclitaxel was the subject of controversy in connection with peripheral artery disease (PAD) seem to be drawing to a close, thanks in part to a new drug-coated balloon (DCB) by Trireme Medical Inc., of Pleasanton, Calif. Trireme’s Chocolate Touch device, a second-generation DCB with paclitaxel as an antiproliferative, fared well against a legacy paclitaxel device, thus opening a new front in the competition in the PAD space and seemingly relieving any concerns about the safety of paclitaxel.

The FDA has granted approval to Urotronic Inc. for its Optilume urethral drug-coated balloon (DCB) for the treatment of male urethral strictures. The device inhibits new scar tissue growth that may form after endoscopic dilations via the controlled release of paclitaxel, an antiproliferative that inhibits scar tissue formation.
