To determine the dose of trabectedin plus doxorubicin with granulocyte colony stimulating factor (G-CSF) support associated with manageable neutropenia and acceptable dose-limiting toxicities (DLTs) in patients with recurrent or persistent soft tissue sarcoma (STS). In this phase I, open-label, multicenter trial, patients previously treated with 0–1 prior chemotherapy regimens excluding doxorubicin, an ECOG performance status 0–1, and adequate organ function received a 10–15-minute intravenous (IV) infusion of doxorubicin 60 mg/m2 immediately followed by a 3-hour IV infusion of trabectedin 0.9–1.3 mg/m2 on day 1 of a 3-week cycle. Because four of the first six patients experienced DLT-defining neutropenia during cycle 1, all subsequent patients received primary prophylactic G-CSF. The maximum tolerated dose (MTD) was the highest dose level with ≥6 patients in which less than one third of the patients experienced severe neutropenia or DLT. Blood was collected during cycle 1 for pharmacokinetic analyses. Adverse events (AEs), tumor response, and survival were assessed. Patients (N = 41) received a median of six cycles of treatment (range, 2–13). The MTD was trabectedin 1.1 mg/m2 and doxorubicin 60 mg/m2. Common grade 3/4 treatment-emergent AEs were neutropenia (71%), ALT increase (46%), and thrombocytopenia (37%). Overall, five (12%) patients achieved a partial response, and 34 (83%) maintained stable disease. Median progression-free survival was 9.2 months. Doxorubicin and trabectedin pharmacokinetics were not altered substantially with concomitant administration. The combination of doxorubicin 60 mg/m2 followed by trabectedin 1.1 mg/m2 every 21 days is safe and active in patients with STS.
