Temozolomide has established activity in the treatment of recurrentglioblastoma multiforme (GBM). Caelyx (liposomal doxorubicin) has establishedactivity in a broad range of tumors but has not been extensively evaluated inthe treatment of GBM. Phase 1 data suggest that temozolomide and Caelyx can becombined safely at full dose. In this phase 2 study, combination temozolomide(200 mg/m2 orally, days 1-5) and Caelyx (40 mg/m2 i.v.,day 1) was given every 4 weeks to a cohort of 22 patients with recurrent GBM,who received a total of 109 cycles (median 3.5 cycles). The median age of thepatients was 55 years (range, 31-80 years), and 17 were male. All patients hadreceived radiotherapy, but only 2 had received prior chemotherapy. One patient(5%) had a complete response, 3 patients (14%) had a partial response, and 11patients (50%) had stable disease. The median time to progression for thecohort was 3.2 months (range, 1-13 months). Median overall survival was 8.2months (range, 1-16+ months). Seven patients (32%) were progression free at 6months. Hematological toxicity included grade 3/4 neutropenia in 4 patients(18%) and grade 3/4 thrombocytopenia in 4 patients (18%). Grade 3nonhematologic toxicity included rash in 3 patients (14%), nausea and vomitingin 1 patient (4%), hypersensitivity reaction to Caelyx in 3 patients (14%),and palmar-plantar toxicity in 1 patient (4%). We conclude that thecombination of temozolomide and Caelyx is well tolerated, results in a modestobjective response rate, but has encouraging disease stabilization in thetreatment of recurrent GBM.
