Phase I study of the taxane BMS-188797 in combination with carboplatin administered every 3 weeks in patients with solid malignancies.
BMS-188797 is one of several novel taxanes in ongoing clinical development. It has superior activity in experimental tumor models when compared with paclitaxel. BMS-188797 has a single C-4 modification, a 4-desacetyl-4-methylcarbonate, compared with paclitaxel.. We did a phase I study, in which a fixed dose of carboplatin was combined with a dose escalation schedule of BMS-188797, both administered once every 3 weeks, in patients with advanced solid malignancies.. Thirty patients were treated, 11 at the proposed recommended phase II dose. The dose-limiting toxicity was myelosuppression. There was a linear relationship between administered dose of BMS-188797 and the measured area under the curve (AUC). There was significant interpatient variability of BMS-188797 AUC at the maximum tolerated dose. Two radiographic partial responses were observed: one patient with duodenal adenocarcinoma and one patient with esophageal adenocarcinoma (time on study, 19 and 30 weeks, respectively).. The recommended phase II dose for BMS-188797 and carboplatin administered on a once-every-3 week schedule is carboplatin AUC = 5 mg min/mL and BMS-188797 at a dose of 135 mg/m(2).

A phase I and pharmacokinetic study of novel taxane BMS-188797 and cisplatin in patients with advanced solid tumours.
This phase I study investigated the maximum tolerated dose and pharmacokinetics of a 3-weekly administration of BMS-188797, a paclitaxel derivate, at three dose levels (DLs) (80, 110 and 150 mg m(-2) DL), combined with cisplatin (standard dose 75 mg m(-2)). In 16 patients with advanced malignancies treated, one patient experienced dose-limiting febrile neutropenia, sepsis and severe colitis at the 150 mg m(-2) DL; at the 110 mg m(-2) DL one episode of dose-limiting grade 3 diarrhoea/nausea occurred. Grade 3/4 haematological toxicities were leucopenia/neutropenia; grade 3 nonhaematological toxicities were neuropathy, nausea, diarrhoea and stomatits. Objective response was seen in four patients, with three complete remissions in ovarian and cervical cancer patients. Pharmacokinetics of BMS-188797 appeared linear through the 110 mg m(-2), but not through the 150 mg m(-2) DL. The mean+/-SD values for clearance, distribution volume at steady state and terminal half-life during cycle 1 were 317+/-60 ml min(-1) m(-2), 258+/-96 l m(-2) and 30.8+/-7.7 h, respectively. The maximum tolerated and recommended phase II dose for BMS-188797 was 110 mg m(-2) (1-h infusion, every 3 weeks) combined with cisplatin 75 mg m(-2).

Phase I study of a novel taxane BMS-188797 in adult patients with solid malignancies.
Preclinical studies show that BMS-188797 has a broad spectrum of antitumor activity in in vitro cytotoxicity assays and tumor xenograft models. We did a phase I trial designed to determine the maximum tolerated dose and the pharmacokinetics of BMS-188797 when administered i.v.. BMS-188797 was administered i.v. over 60 minutes once every 21 days to 51 patients. The initial dose cohort of 3.75 mg/m(2) was set at approximately one third the lethal dose in dogs. Doses were subsequently escalated in cohorts according to a modified Fibonacci design.. Fifty-one patients received a total of 160 cycles of therapy. The dose-limiting toxicity of febrile neutropenia occurred in two patients at the 200 mg/m(2) cohort. Moderate to severe sensory neuropathy occurred in 12 patients (24%). Four radiographic partial responses based on the Response Evaluation Criteria in Solid Tumors occurred: two in subjects with breast cancer, one in a subject with non-small cell lung cancer, and one in a subject with renal cell carcinoma. The duration of the partial responses observed were 24.1 months (renal cell carcinoma), 5.7 and 4.3 months (breast cancer), and 4.5 months (non-small cell lung cancer). Pharmacokinetics appear linear at doses through 110 mg/m(2) but not at higher doses.. The dose-limiting toxicity in this single-agent study of BMS-188797 was febrile neutropenia. The recommended phase II dose of BMS-188797 as a single agent is 175 mg/m(2) i.v. for 1 hour administered every 3 weeks.

Phase I and pharmacokinetic trial of the novel taxane BMS-184476 administered as a 1-hour intravenous infusion in combination with cisplatin every 21 days.
BMS-184476 is a 7-methylthiomethyl ether derivative of paclitaxel that displays potency superior to paclitaxel against tumor cells in culture and human tumor xenografts. It also inhibits the growth of paclitaxel-resistant human tumor cell lines with multidrug resistance mediated by either P-glycoprotein or mutated tubulin. Given the known synergy between taxanes and cisplatin in vitro and their clinical activity in combination, we performed a Phase I trial of BMS-184476 as a 1-h i.v. infusion followed by cisplatin every 21 days. Twenty-seven patients with a variety of solid tumors and good performance status received 116 cycles of therapy at BMS-184476 doses of 40-60 mg/m(2) together with cisplatin at 75 mg/m(2). The early observation of hypersensitivity reactions required prophylactic premedication in all patients. At the planned highest dose of BMS-184476 (60 mg/m(2)) and cisplatin (75 mg/m(2)), we observed dose-limiting toxicity in the form of neutropenia and diarrhea. Also at this level, five patients experienced grade 3 or worse nausea and vomiting. Aggressive prophylactic treatment eliminated the gastrointestinal toxicity. Mild to moderate peripheral neuropathy was infrequent, as was alopecia. Patient benefits included three partial responses in patients with mesothelioma, esophageal cancer, and head and neck cancer, and two additional minor responses. Plasma pharmacokinetic data are available for 23 patients treated at 40-60 mg/m(2). The mean maximum plasma concentrations and areas under the curves increased in a dose-related manner. The pharmacokinetics of BMS-184476 appeared independent of dose. The mean (+/- SE) values for clearance, volume of distribution at steady state, and the apparent terminal half-lives of the three dose groups during cycle 1 were 243 +/- 5 ml/min/m(2), 423 +/- 58 l/m(2), and 32.2 +/- 4.5 h, respectively. BMS-184476 60 at mg/m(2) with cisplatin at 75 mg/m(2) with appropriate supportive therapy is the dose recommended for further evaluation.

Phase I and pharmacokinetic study of BMS-188797, a new taxane analog, administered on a weekly schedule in patients with advanced malignancies.
The purpose of this study was to establish the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), and preliminary activity of BMS-188797 administered weekly.. Patients with advanced malignancies were treated with escalating doses of BMS-188797 on a weekly schedule as a 1-h i.v. infusion. Plasma sampling was performed to characterize the pharmacokinetics of BMS-188797.. Eighteen patients with advanced malignancies were enrolled at three dose levels ranging from 35 to 65 mg/m(2). The number of patients evaluated at each dose level was as follows: 35 mg/m(2) (n = 3); 50 mg/m(2) (n = 9); and 65 mg/m(2) (n = 6). At 65 mg/m(2), three of six patients had a DLT (one had grade 4 neutropenia lasting >7 days, and two had grade 3 diarrhea). Expansion of the 50-mg/m(2) dose cohort to nine patients established this dose as the MTD, with one patient experiencing a DLT (grade 4 neutropenia with fever). Two partial responses were observed (lung cancer, 7+ months; ovarian cancer, 6+ months durations), as well as two minor responses (esophageal cancer, 5 months; ovarian cancer, 5 months). Both patients with partial responses had been clinically resistant to paclitaxel. Plasma pharmacokinetic mean values of maximum concentration (C(max)) and area under the curve (AUC(0-48)) increased in a dose-dependent manner within the range of doses used in this study, and in three of four patients, the DLTs correlated with AUC.. The MTD and the recommended Phase II dose of weekly BMS-188797 is 50 mg/m(2). The drug demonstrates antitumor activity in taxane-refractory solid tumors and is now being evaluated in combination with carboplatin.
