Abstract

BACKGROUND:

Pegylated liposomal doxorubicin (PEG-LD) and docetaxel have single-agent activity in several malignancies. The authors conducted a Phase I trial to evaluate the maximum tolerated dose (MTD), toxicities, and effect of dose sequencing of this combination in patients with advanced malignancies.

METHODS:

Twenty-two patients were enrolled in this two-arm, accelerated, dose escalation trial. Both drugs were administered on Days 1 and 15 of a 28 day cycle. In Arm A, dose escalation proceeded from a sequence and starting dose of 15 mg/m(2) PEG-LD and 30 mg/m(2) docetaxel. In Arm B, dose escalation proceeded from a sequence and starting dose of 30 mg/m(2) docetaxel and 15 mg/m(2)PEG-LD. In both arms, the dose of each drug was increased alternately by 5 mg/m(2) at each dose level.

RESULTS:

The MTD for Arm A was 20 mg/m(2) PEG-LD and 40 mg/m(2) docetaxel, both of which were administered on Days 1 and 15 of a 28-day cycle. The MTD for Arm B was 35 mg/m(2) docetaxel and 20 mg/m(2) PEG-LD, both of which were administered on Days 1 and 15 of a 28-day cycle. Dose-limiting toxicities were Grade 3 (according to the National Cancer Institute Common Toxicity Criteria) skin toxicity and thrombocytopenia. One partial response was observed and stable disease was documented for three patients.

CONCLUSIONS:

The recommended sequence and dose is 20 mg/m(2) PEG-LD followed by 40 mg/m(2) docetaxel on Days 1 and 15 of a 28-day cycle in Phase II trials for patients with breast and ovarian carcinoma to establish the efficacy of this well tolerated regimen.
