Preliminary results of a phase I study of paclitaxel (Taxol; Bristol- Myers Squibb Company, Princeton, NJ), given by 3-hour infusion, followed by carboplatin in chemotherapy-naive patients with stage IV non-small cell lung cancer indicate that both agents can be combined at clinically relevant single-agent doses. The paclitaxel (mg/m2)/carboplatin area under the concentration-time curve (mg · min/mL) dose level of 225/7 is projected to be the maximally tolerated and recommended phase II dose level for future evaluations. Dose-limiting neutropenia, thrombocytopenia, and nausea and vomiting preclude treatment with carboplatin doses estimated to target an area under the concentration-time curve of 9 mg · min/mL when given with paclitaxel 225 mg/m2. The heterogeneous nature of the principal toxicities, as well as the ability to administer clinically relevant single-agent doses of both agents in combination, also indicate that further dose escalation of paclitaxel and carboplatin using hematopoietic growth factors would not be feasible. The preliminary antitumor activity noted to date, as well as the safety associated with the clinically relevant single-agent doses that can be given in combination, indicate that phase II/III evaluations of this regimen are warranted in patients with both advanced and early stage non-small cell lung cancer.
