In the randomised clinical trials in metastatic leiomyosarcoma or liposarcoma and in recurrent platinum-sensitive ovarian cancer, trabectedin is infused at 1.5 mg/m2 as a 24-hour infusion or 1.3 mg/m2 as a 3 hour infusion every 3 weeks (see citations). Balancing efficacy with safety the short infusion is preferable in clinical practice.
