Madrid, January 5th 2015: PharmaMar announces that Taiho Pharmaceutical, PharmaMar's partner for Yondelis® development and sales in Japan, has filed a marketing authorization application that seeks approval of Yondelis® (trabectedin; development code: ET-743) for the treatment of different subtypes of advanced soft tissue sarcoma in Japan, given the clinical benefit shown in a pivotal Phase II study.
"This is a milestone for PharmaMar and a step forward for Yondelis®, which keeps showing its efficacy as treatment for this type of cancer", said Luis Mora, Managing Director, PharmaMar. "We hope that patients suffering from soft tissue sarcoma in Japan will soon have access to this treatment".
This J-NDA is based on the results from the open-label, randomized Phase II clinical study (JapicCTI-121850) that compared the progression-free survival (PFS) of Japanese patients treated with Yondelis® (trabectedin) against best supportive care (BSC), which was the primary endpoint. The data, presented at the 2014 ASCO, showed a median PFS of 5.6 months for Yondelis® (trabectedin), which was significantly superior compared to the 0.9 months achieved by patients on BSC1.
