BACKGROUND: The primary objectives of this study were to determine the efficacy and tolerability of a pemetrexed-carboplatin combination as first-line therapy in patients with advanced nonsmall cell lung cancer. METHODS: Eligibility criteria included Zubrod performance status of 0 or 1, Stage IIIB (malignant effusion) or IV disease, and no prior chemotherapy. Treatment was pemetrexed 500 mg/m2 given intravenously and carboplatin area under the serum concentration-time curve = 6 given intravenously on Day 1 every 3 weeks for six cycles; patients could receive additional cycles at the discretion of the treating physician and patient. All patients received folic acid, vitamin B12, and dexamethasone prophylaxis. RESULTS: Fifty patients (31 men and 19 women) were treated. The median age was 62 years. Ninety-six percent of patients had Stage IV disease, and 88% had a performance status of 1. The median number of cycles was 6; 15 patients received 8 or more cycles. There was Grade 3/4 neutropenia in 11 (22%) and 2 (4%) patients, respectively; Grade 3/4 thrombocytopenia in 1 (2%) and 0 patients, respectively. Three patients (6%) experienced Grade 3 nonhematologic side effects (diarrhea, neutropenic pneumonia, and fatigue). No patients had sensory neuropathy or alopecia >Grade 1. The partial response rate was 24%, median time to progression 5.4 months, 1-year survival 56.0%, and median survival 13.5 months. CONCLUSIONS: This is an active, very well-tolerated regimen. Trials focused on how to integrate this doublet with novel agents are warranted.
