Multicenter Study Clinical TrialDose-escalated paclitaxel in 1-hour infusion with a fixed dose of cisplatin in previously untreated advanced ovarian cancer: a phase II trial of the Spanish Group for Ovarian Cancer.
This phase II trial was planned to study the efficacy and toxicity of a fixed dose of cisplatin plus paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given over 1 hour with intrapatient dose escalation. Patients with advanced epithelial ovarian cancer (stages IIB-IV); Eastern Cooperative Oncology Group performance status < or = 2; normal renal, liver, and bone marrow function; and evaluable residual disease after debulking surgery were accrued. Paclitaxel was given over 1-hour infusion and dose was escalated from 175 to 200 and 225 mg/m2 if nadir neutrophil counts were > or = 1000/microL, platelets were > or = 100,000/microL, and neurotoxicity was less than grade 2. ⋯ Peripheral neurotoxicity (grade 1, 39.7%; grade 2, 42.6%; and grade 3, 8.8%) was dose-limiting. It is too early to report on time to progression and survival, and these data are not yet available. This combination of cisplatin with escalating doses of paclitaxel is feasible and very active, but the high incidence of peripheral neurotoxicity may limit its use.

Multicenter Study Clinical TrialPaclitaxel in platinum-resistant ovarian cancer patients. Argentine Multicenter Taxol Group.
Paclitaxel (Taxol; Bristol-Myers Squibb Company; Princeton, NJ) is an antineoplastic agent that inhibits microtubular function and has shown efficacy in several solid tumors, mainly ovarian tumors, in which 20% to 40% response rates in previously treated patients were observed. We conducted a study to assess survival, response rate, and toxicity associated with paclitaxel treatment in patients with advanced ovarian cancer resistant to platinum therapy. Between September 1994 and November 1996, 38 patients were admitted for study and 37 were evaluable. ⋯ Mild to moderate hematologic toxicity was observed with only one episode of grade 4 neutropenia, without fever. Gastrointestinal toxicity was moderate and peripheral neuropathy was mild, except for two patients who had concomitant pathologies or previous treatment, which might have caused some neuropathy. We concluded that paclitaxel given as a 3-hour infusion was easily administered for ambulatory treatment, with mild to moderate toxicity and promising results based on rate and duration of response as well as survival.

Randomized Controlled Trial Multicenter Study Clinical TrialCarboplatin plus paclitaxel as first-line chemotherapy in previously untreated advanced ovarian cancer. German AGO Study Group Ovarian Cancer. Arbeitsgemeinschaft Gynäkologische Onkologie.
Since publication of the results of the Gynecologic Oncology Group (GOG) III study, the combination of cisplatin and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) has been adopted widely as the new standard for treating advanced ovarian cancer. Further attempts to optimize first-line chemotherapy with platinum and taxanes include substituting carboplatin for cisplatin, individualizing the carboplatin dose by calculating it according to the area under the concentration-time curve, and reducing the length of the paclitaxel infusion. Attempts to optimize platinum/paclitaxel combinations have led to the initiation of several small phase I/II trials evaluating the carboplatin/paclitaxel combination. ⋯ Retrospective comparison with the GOG results reveals no significant difference in response rates between patients in the cisplatin/paclitaxel arm of GOG III and those in the AGO study: the GOG study reported a 73% response rate, compared with a preliminary 75% response rate in the AGO study, resulting in a relative risk of 1.03 (95% confidence interval, 0.83 to 1.27). Overall, this interim analysis did not reveal any reason to terminate this study early. Accrual is ongoing and is expected to be completed in 1997.

Multicenter Study Clinical TrialDocetaxel (Taxotere) and gemcitabine in the treatment of non-small cell lung cancer: preliminary results.
A phase II study was performed to investigate the tolerance and efficacy of the combination of docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) and gemcitabine in chemotherapy-naive patients with advanced non-small cell lung cancer (NSCLC). To date, 24 patients (five with stage IIIB and 19 with stage IV NSCLC) have been treated according to the protocol: gemcitabine 900 mg/m2 was administered on days 1 and 8 as a 30-minute infusion and docetaxel 100 mg/m2 was administered on day 8 as a 1-hour infusion after appropriate premedication. Granulocyte colony-stimulating factor 150 microg/m2 subcutaneously was given on days 9 to 15. ⋯ The median delivered dose was 600 mg/m2/wk and 33 mg/m2/wk for gemcitabine and docetaxel, respectively. These preliminary data suggest that the docetaxel/gemcitabine combination has significant antitumor activity and is well tolerated in chemotherapy-naive patients with NSCLC. The study is ongoing.

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.
