Abstract

PURPOSE:

To summarize the safety experience obtained from phase II clinical trials conducted with trabectedin as single-agent therapy in patients with advanced solid tumors.

METHODS:

This retrospective analysis includes 1,132 patients exposed to trabectedin in 19 phase II trials carried out between February 1999 and April 2008. Trabectedin was administered intravenously as 1 of 3 schedules: 24-hour infusion every 3 weeks (q3wk 24-h; n = 570/2,818 cycles), 3-hour infusion every 3 weeks (q3wk 3-h; n = 258/1,003 cycles), and 3-hour infusion for three consecutive weeks every 4 weeks (qwk 3-h; n = 304/1,198 cycles).

RESULTS:

The majority of patients (90%) had received previous chemotherapy. Patients were given a median of three treatment cycles of trabectedin (range, 1-59). Nausea, fatigue and vomiting were the most common trabectedin-related adverse events, reported in ≥20% of patients. Reversible myelosuppression (mainly neutropenia) and transient reversible transaminase increases were the most common laboratory abnormalities seen with trabectedin, with a very low incidence of relevant clinical consequences. Deaths associated with drug-related adverse events were infrequent, occurring in 19 (1.7%) patients.

CONCLUSION:

Single-agent trabectedin treatment was reasonably well tolerated. Trabectedin can be administered for prolonged periods to patients with sustained clinical benefit (induction of disease stability or shrinkage) without cumulative toxicities over time.
