Pemetrexed combined with paclitaxel in patients with advanced or metastatic non-small-cell lung cancer: a phase I-II trial.

Pemetrexed, a novel multi-targeted agent established for the treatment of mesothelioma, has been under investigation for other malignancies, and in recent years particularly for non-small-cell lung cancer (NSCLC). In the present trial we investigated pemetrexed in combination with paclitaxel as front-line treatment in advanced or metastatic NSCLC. Our objectives were to determine the response rate, median and overall survival and toxicity. From April 2005 until May 2006, 51 patients with advanced or metastatic NSCLC were enrolled and 48 were considered evaluable. There were 39 males and nine females, median age 62 years (range 37-81 years), one patient stage IIIA N(2), 23 patients, IIIB and 24, stage IV. All patients had a cytologically- or histologically-confirmed diagnosis. Pemetrexed was administered at a standard dose of 500mg/m(2) and paclitaxel at an escalating dose starting at 135mg/m(2), then 150mg/m(2) and ending at a dose of 175mg/m(2); the level was increased every three patients. Both agents were administered on day 1, repeated every 3 weeks for six courses. A 39.6% partial response rate was observed with a median survival of 14 months. Toxicity was mild with 8.3% grade 3 and 4 neutropenia and other very mild hematologic and non-hematologic adverse reactions. The combination of pemetrexed and paclitaxel at doses of 500mg/m(2) and 175mg/m(2), respectively, has been shown to be an effective combination with very limited toxicity.

Vinorelbine plus cisplatin versus docetaxel plus gemcitabine in advanced non-small-cell lung cancer: a phase III randomized trial.

PURPOSE To compare the activity and tolerability of docetaxel/gemcitabine (DG) and vinorelbine/cisplatin (VC) combinations in chemotherapy-naive non-small-cell lung cancer (NSCLC) patients. PATIENTS AND METHODS Patients with advanced NSCLC were randomly assigned to receive either DG (gemcitabine 1,000 mg/m(2) [days 1 and 8] plus docetaxel 100 mg/m(2) [day 8]) or VC (vinorelbine 30 mg/m(2) [days 1 and 8] plus cisplatin 80 mg/m(2) [day 8]) and prophylactic recombinant human granulocyte colony-stimulating factor (150 microg/m(2) subcutaneously [day 9 through 15]) every 3 weeks. Results A total of 413 randomly assigned patients were analyzed for response and toxicity (DG, n = 197; VC, n = 192). Median survival was 9.0 and 9.7 months (P = .965) for DG and VC arms, respectively; the corresponding 1-year survival rates were 34.3% and 40.8%, respectively. Overall response rate was 30% (95% CI, 23.9% to 36.3%) and 39.2% (95% CI, 32.5% to 45.9%; P = .053) for DG and VC, respectively. Toxicity was as follows (DG v VC): grade 2 to 4 anemia, 34% v 55% (P = .0001); grade 3 to 4 neutropenia, 16% v 37% (P = .0001); febrile neutropenia, 6% v 11% (P = .009); and grade 3 to 4 nausea and vomiting, 1% v 15% (P = .003). Nephrotoxicity occurred in 8% and ototoxicity in 2% of VC-treated patients. There were five and six treatment-related deaths in the DG and VC arms, respectively. Quality of life was improved in DG but not in VC patients. CONCLUSION Although the two regimens produced comparable overall survival, the DG regimen had a better toxicity profile. Therefore, DG could be used in the first-line setting of advanced NSCLC, especially for patients who cannot tolerate cisplatin.
