title: Irinotecan, epirubicin, and capecitabine in metastatic adenocarcinomas: preliminary results of a phase I study.
abstract: The combination of irinotecan (Camptosar), epirubicin, and capecitabine (Xeloda) has shown an acceptable toxicity profile. In this open-label phase I study, irinotecan was administered IV at a fixed dose of 250 mg/m2 on day 1 in combination with capecitabine at a fixed dose of 1500 mg/m2 for days 2 to 7 and epirubicin starting at a dose of 40 mg/m2 and escalating by 10 mg/m2 in cohorts of three patients for those with metastatic adenocarcinomas. With the addition of granulocyte colony-stimulating factor (G-CSF [Neupogen]) to the regimen, patients received epirubicin at clinically relevant doses after dose-escalation. Results of the topoisomerase activity will be reported with the final results of this phase I study. The dose-limiting toxicity has not yet been reached. This combination regimen in patients with upper gastrointestinal malignancies and breast cancer will be investigated as part of phase II studies, once the dose-limiting toxicity is determined. The appropriate sequencing of the regimen to maximize clinical efficacy will also be determined.
