    To determine the safety, tolerability, and pharmacokinetics and to seek preliminary evidence of anticancer activity of tasidotin (ILX651), a novel dolastatin analogue, when administered as a 30-minute i.v. infusion weekly for 3 weeks every 4 weeks.. Thirty patients with advanced solid malignancies were treated with 82 courses at six dose levels ranging from 7.8 to 62.2 mg/m2 weekly, initially according to an accelerated dose-escalation scheme, which evolved into a Fibonacci scheme as a relevant degree of toxicity was observed. Plasma and urine were sampled to characterize the pharmacokinetic behavior of tasidotin.. A high incidence of neutropenia complicated by fever (one patient), or precluding treatment on day 15 (three patients), was the principal toxicity of tasidotin, at doses above 46.8 mg/m2. At all dose levels, nonhematologic toxicities were generally mild to moderate and manageable. Grade 3 toxicities included diarrhea and vomiting (one patient each). Drug-induced neurosensory symptoms were mild and there was no evidence of cardiovascular toxicity, which has been previously associated with other dolastatins. Tasidotin pharmacokinetics were mildly nonlinear, whereas metabolite kinetics were linear. A patient with non-small cell lung carcinoma experienced a minor response, and a patient with hepatocellular carcinoma had stable disease lasting 11 months.. The recommended dose for phase II studies of tasidotin administered on this schedule is 46.8 mg/m2. The mild myelosuppression and manageable nonhematologic toxicities at the recommended dose, the evidence of antitumor activity, and the unique mechanistic aspects of tasidotin warrant further disease-directed evaluations on this and alternative schedules.

A phase I study of the dolastatin-15 analogue tasidotin (ILX651) administered intravenously daily for 5 consecutive days every 3 weeks in patients with advanced solid tumors.

    To determine the maximum tolerated dose, dose-limiting toxicity, and pharmacokinetics of the dolastatin-15 analogue, tasidotin (ILX651), when administered i.v. daily for 5 days every 3 weeks.. Thirty-six patients with advanced solid tumors received a total of 114 courses through eight dose levels ranging from 2.3 to 36.3 mg/m(2). Pharmacokinetic samples were collected in cycle 1.. Neutropenia was the principal dose-limiting toxicity at 36.3 mg/m(2)/d along with grade 3 ileus and elevated aspartate amino transaminase/alanine amino transaminase (n = 1). At the maximum tolerated dose, 27.3 mg/m(2), 4 of 14 patients experienced dose-limiting grade 4 neutropenia. The other principal toxicities consisted of mild-to-moderate elevated transaminases, alopecia, fatigue, and nausea. One patient with melanoma metastatic to liver and bone treated at 15.4 mg/m(2)/d experienced a complete response and received 20 courses of tasidotin. Two other patients with melanoma had mixed responses of cutaneous metastases at 27.3 mg/m(2)/d associated with either stable or progressive visceral disease. In addition, nine patients had stable disease. There was no accumulation of tasidotin following repeated daily dosing. Tasidotin decayed from plasma in a biphasic fashion with a half-life of <45 minutes in most cases.. The maximum tolerated dose and recommended phase II dose for tasidotin when administered on this schedule was 27.3 mg/m(2)/d. The favorable toxicity profile of tasidotin compared with other antitubulin agents (particularly the lack of severe cumulative neuropathy, peripheral edema, and fatigue), the observed antitumor activity of tasidotin, and its novel mechanism of action support further disease-directed evaluations of this agent on this 5-day schedule every 3 weeks.

Phase I and pharmacokinetic study of the dolastatin-15 analogue tasidotin (ILX651) administered intravenously on days 1, 3, and 5 every 3 weeks in patients with advanced solid tumors.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2005, Nov-01, Volume: 11, Issue:21

    To determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), and pharmacokinetics of tasidotin (ILX651), a dolastatin-15 analogue, when administered on days 1, 3, and 5 every 3 weeks in patients with advanced solid tumors.. Thirty-two patients were treated with 92 courses of tasidotin through seven dose levels determined by a modified Fibonacci scheme ranging from 3.9 to 45.7 mg/m(2). Pharmacokinetic samples were collected during the first course.. Neutropenia was the principal DLT at the 45.7 mg/m(2)/d dose level. In addition, one patient also experienced grade 3 neutropenia complicated with grade 3 esophageal candidiasis and grade 3 dehydration. Only 1 of 11 patients treated at the MTD, 34.4 mg/m(2), experienced dose-limiting neutropenia. Other common, drug-related toxicities included mild to moderate fatigue, anemia, nausea, anorexia, emesis, alopecia, and diarrhea. The best observed antitumor response consisted of stable disease and was noted in 10 patients (31%); the median duration on study for those patients with stable disease was 99.5 days compared with 37.5 days for those patients with progressive disease. Tasidotin plasma concentrations declined biphasically with an effective half-life of < or =55 minutes, and approximately 11% was excreted unchanged in the urine.. The recommended dose for phase II studies and the MTD when tasidotin is administered on days 1, 3, and 5 every 3 weeks is 34.4 mg/m(2). The favorable toxicity profile of tasidotin compared with other antitubulin agents, including other dolastatin analogues, and its novel mechanism of action support further disease-directed evaluation of this agent.
