The approval was based on the clinical efficacy and safety data from a recently published Phase 3, randomized, open-label, controlled study, ET743-SAR-3007, which evaluated YONDELIS^® versus dacarbazine in this patient population^[i]. This pivotal trial confirmed the results of previous clinical studies and provides strong evidence of the clinical benefit of trabectedin.

"Since YONDELIS^® was first approved in Europe in 2007 approximately 50,000 patients in 80 countries have benefited from this therapy across all indications," says Luis Mora, Managing Director, PharmaMar, who added that "the approval in the U.S. will allow more patients with this disease to have access to a drug that will address an unmet medical need."

For the approval of YONDELIS^® in the U.S., PharmaMar will receive the appropriate milestone from Janssen Products, LP.
