Abstract
PURPOSE
Pre-clinical models have demonstrated the benefit of metronomic schedules of cytotoxic chemotherapy combined with anti-angiogenic compounds. This trial was undertaken to determine the toxicity of a low dose regimen using docetaxel and thalidomide.
PATIENTS AND METHODS
Patients with advanced solid tumors were enrolled. Thalidomide 100mg twice daily was given with escalating doses of docetaxel from 10 to 30 mg/m(2)/week. One cycle consisted of 12 consecutive weeks of therapy. The maximal tolerated dose (MTD) was defined as the dose of thalidomide along with docetaxel that caused < or =grade 1 non-hematologic or < or =grade 2 hematologic toxicity for cycle one.
RESULTS
Twenty-six patients were enrolled. Dose-limiting toxicities (DLTs) were bradycardia, fatigue, fever, hyperbilirubinemia, leukopenia, myocardial infarction, and neutropenia. Prolonged freedom from disease progression was observed in 44.4% of the evaluable patients.
CONCLUSIONS
This anti-angiogenic regimen was well tolerated and demonstrated clinical benefit. The recommended phase II dosing schedule is thalidomide 100 mg twice daily with docetaxel 25 mg/m(2)/week.
