Multicenter Study Clinical TrialPaclitaxel (1-hour infusion) plus carboplatin in the treatment of advanced non-small cell lung cancer: results of a multicenter phase II trial.
This study was performed to determine the activity and toxicity of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given by 1-hour infusion plus carboplatin in the treatment of patients with advanced non-small cell lung cancer when used in a multicenter, community-based setting. The study population included 100 chemotherapy-naive patientswith stage IIIB or IV non-small cell lung cancer, Karnofsky performance status 70 to 100, measurable disease, and adequate kidney, liver, and bone marrow function. All patients received paclitaxel 225 mg/m2 intravenously by 1-hour infusion followed immediately by carboplatin at a targeted area under the concentration-time curve of 6.0 (Calvert formula). ⋯ One patient died as a result of treatment due to sepsis. This large, multicenter, community-based phase II trial demonstrates the efficacy of paclitaxel/carboplatin combination chemotherapy in advanced non-small cell lung cancer. This regimen is relatively well tolerated and when paclitaxel is given by 1-hour infusion, this treatment is easily administered in the outpatient setting.

Comparative Study Clinical TrialPaclitaxel by either 1-hour or 24-hour infusion in combination with carboplatin in advanced non-small cell lung cancer: preliminary results comparing sequential phase II trials.
Our group previously described the activity of carboplatin plus paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) (given as a 24-hour infusion) in 51 patients with advanced non-small cell lung cancer. To facilitate outpatient administration, the regimen was modified to infuse paclitaxel over 1 hour. Between February 1995 and August 1996, 63 patients with advanced non-small cell lung cancer were accrued by the Vanderbilt Cancer Center and its affiliate network. ⋯ Likewise, the incidence of grade 1 to 3 arthralgia/myalgia was greater among patients receiving 1-hour infusion of paclitaxel (3.5% v 28%). Although not randomized, these data suggest that survival may be comparable whether paclitaxel is given by short or prolonged infusion in advanced non-small cell lung cancer. Toxicity profiles differ, however, with greater myelosuppression following 24-hour paclitaxel, but a higher incidence of neurotoxicity and arthralgia/myalgia with the 1-hour infusion.

Clinical TrialA phase II study evaluating the efficacy of carboplatin, etoposide, and paclitaxel with granulocyte colony-stimulating factor in patients with stage IIIB and IV non-small cell lung cancer and extensive small cell lung cancer.
We initiated a phase II pilot study to determine whether adding paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) to combination carboplatin/etoposide is tolerable and active in patients with advanced non-small cell lung cancer and extensive small cell lung cancer. Patients were given carboplatin (area under the concentration-time curve of 6) followed by etoposide 80 to 100 mg/m2 intravenously on days 1 through 3 followed by paclitaxel 200 mg/m2 intravenously over 3 hours on day 3. On days 4 through 18, granulocyte colony-stimulating factor 5 microg/kg was administered subcutaneously. ⋯ None of the four patients with non-small cell lung cancer responded to treatment, while six of seven small cell lung cancer patients have obtained major responses to therapy. We have increased the etoposide dose to 100 mg/m2 in subsequent patients. The combination chemotherapy regimen of carboplatin, etoposide, and paclitaxel is tolerable and active in patients with small cell lung cancer.

Clinical TrialTwice-weekly paclitaxel and radiation for stage III non-small cell lung cancer.
A phase I study was conducted to investigate the safety and efficacy of twice-weekly paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and concurrent thoracic irradiation in patients with stage III non-small cell lung cancer. Radiation therapy beginning on day 1 was delivered in 1.8- to 2.0-Gy daily fractions, to a total dose of 61 Gy. Paclitaxel at a starting dose of 25 mg/m2/d was administered intravenously over 1 hour before daily radiation on days 1, 4, 8, 11, 15, 18, 22, 25, 29, 32, 36, and 39, for a total of 12 doses over 6 weeks. ⋯ Response rates ranging from 50% to 100% were observed (three of six patients at paclitaxel 25 mg/m2, four of six at 30 mg/m2, seven of seven at 35 mg/m2, six of six at 40 mg/m2), for an overall response rate of 80%. We conclude that the maximum tolerated dose of paclitaxel is 35 mg/m2 given twice weekly in a 1-hour infusion for 6 weeks concurrently with thoracic irradiation. This study provides the basis for an ongoing trial combining twice-weekly paclitaxel and carboplatin with concurrent thoracic irradiation for patients with stage III non-small cell lung cancer.

Clinical TrialSecond-line treatment of advanced non-small cell lung cancer with paclitaxel and gemcitabine: a preliminary report on an active regimen.
A phase II study of combination paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ)/gemcitabine was conducted in patients with non-small cell lung cancer (NSCLC) who had failed first-line docetaxel- or cisplatin-based chemotherapy. Eligibility criteria included histologically confirmed measurable stage IIIB or IV NSCLC and previous exposure to docetaxel- or cisplatin-based regimens, World Health Organization performance status between 0 and 2, adequate hematologic parameters, and adequate hepatic, renal, and cardiac function. Gemcitabine (900 mg/m2) was given on days 1 and 8 as a 30-minute infusion; paclitaxel (175 mg/m2) was administered on day 8 as a 3-hour infusion after appropriate premedication. ⋯ Other toxicities were mild to moderate. These preliminary results suggest that the paclitaxel/gemcitabine combination is an active and well-tolerated salvage regimen in patients with NSCLC previously treated with docetaxel- or cisplatin-based chemotherapy. The paclitaxel/gemcitabine combination merits further evaluation as first-line treatment.
