Randomized Controlled Trial Clinical TrialA phase II study of cisplatin, 5-fluorouracil, and leucovorin augmented by vinorelbine (Navelbine) for advanced non-small cell lung cancer: rationale and study design.
In a randomized phase II study by the Cancer and Leukemia Group B, the cisplatin/5-fluorouracil/leucovorin (PFL) combination produced a 29% response rate in advanced, unresectable non-small cell lung cancer. Vinorelbine (Navelbine; Burroughs Wellcome, Co, Research Triangle Park, NC; Pierre Fabre Médicament, Paris, France), a semisynthetic vinca alkaloid, has also demonstrated single-agent activity in this disease. Therefore, a phase I-II study was designed to investigate the addition of vinorelbine in escalating doses to the PFL combination. ⋯ It was concluded that this dose level was not feasible. During a preliminary analysis, one complete response and three partial responses were observed in 16 patients evaluated; one of these patients had a pathologic complete remission. This early analysis indicates activity for the regimen.

Randomized Controlled Trial Multicenter Study Clinical TrialPrevention of chemotherapy-induced nausea and vomiting by tropisetron (Navoban) alone or in combination with other antiemetic agents.
We report an open, three-armed, multicenter study being carried out to assess the optimum treatment for acute and delayed emesis and nausea in patients undergoing highly emetogenic chemotherapy. Eighty-seven patients were randomized to receive tropisetron (Navoban; Sandoz Pharma Ltd, Basel, Switzerland), tropisetron plus dexamethasone, or tropisetron plus metoclopramide during chemotherapy. Tropisetron in combination with dexamethasone produced the best control of both acute and delayed emesis. ⋯ In the tropisetron and tropisetron plus metoclopramide treatment groups, a decreased food intake was observed due to delayed nausea while the addition of dexamethasone prevented loss of appetite. The antiemetic treatments were similarly well tolerated. The most common adverse events were constipation (15%) and tiredness (7%).

Multicenter Study Clinical TrialPreliminary results of two dose-finding studies of paclitaxel (Taxol) and carboplatin in non-small cell lung and ovarian cancers: a European Cancer Centre effort.
Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given as a 24-hour infusion, and carboplatin have activity in advanced non-small cell lung cancer (NSCLC) and ovarian cancer. Two dose-finding studies were initiated to identify the optimal doses for the paclitaxel/carboplatin combination when paclitaxel is given in a 3-hour infusion. The fact that the pharmacologic interaction between paclitaxel and cisplatin increases the toxicity of paclitaxel when cisplatin is given before it also prompted an investigation of the influence of drug sequence on toxicity and pharmacokinetics in the NSCLC trial. ⋯ No difference in toxicity has been observed thus far between the two drug sequences in the NSCLC study. Both studies are still accruing patients as the maximum tolerated doses of paclitaxel in combination with carboplatin have not yet been reached (carboplatin 300 mg/m2 with paclitaxel 175 mg/m2 in the NSCLC study; carboplatin 400 mg/m2 with paclitaxel 150 mg/m2 in the ovarian cancer study). An investigation of maximum tolerated doses with granulocyte colony-stimulating factor support is planned thereafter.

Clinical TrialCarboplatin and radiotherapy in the treatment of head and neck cancer: six years' experience.
Between 1987 and 1991, 103 patients with advanced head and neck carcinoma were treated with radiochemotherapy plus carboplatin. Tumors were located in the oral cavity in 33 patients, the oropharynx in eight, and the hypopharynx in seven. Four patients had a tumor of the epipharynx and three, tumor of the larynx. ⋯ Patients with advanced head and neck carcinomas are either randomized for conventional radiotherapy plus carboplatin or hyperfractionated accelerated irradiation plus carboplatin. As of July 1994, 178 patients have been entered in the study. Results will be evaluated after the study is completed.
