Brief Summary: RATIONALE Drugs used in chemotherapy such as talotrexin work in different ways to stop the growth of tumor cells either by killing the cells or by stopping them from dividing
PURPOSE This phase I trial is studying side effects best way to give and best dose of talotrexin in treating patients with advanced or recurrent solid tumors
Detailed Description: OBJECTIVES
Primary
Determine the maximum tolerated dose of talotrexin in patients in patients with advanced or recurrent solid tumors Determine the safety of this drug in these patients Determine the dose-limiting toxic effects of this drug in these patients
Secondary
Determine the pharmacokinetics of this drug in these patients Correlate pharmacokinetic parameters of this drug or patient characteristics with drug-related toxicity in these patients Determine preliminarily the antitumor efficacy of this drug in these patients
OUTLINE This is an open-label dose-escalation multicenter study
Patients receive talotrexin IV over 5 minutes on day 1 OR days 1 and 8 OR days 1 8 and 15 Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity
Cohorts of 1-6 patients receive escalating doses of talotrexin until the maximum tolerated dose MTD is determined The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity An additional 6-10 patients are treated at the MTD
Patients are followed at 1 month
PROJECTED ACCRUAL A total of 20-40 patients will be accrued for this study within 9-12 months
