First received: May 6, 2003
Last updated: May 29, 2013
Last verified: April 2005

RATIONALE: Drugs used in chemotherapy such as polyglutamate camptothecin may be able to deliver the drug directly to tumor cells while leaving normal cells undamaged.

PURPOSE: Phase I trial to study the effectiveness of polyglutamate camptothecin in treating patients who have advanced cancer.

Condition Intervention Phase
Unspecified Adult Solid Tumor, Protocol Specific Drug: polyglutamate camptothecin Phase 1

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: Phase I Study of CT-2106 in Patients With Advanced Malignancy

Further study details as provided by National Cancer Institute (NCI):

Study Start Date: January 2003
Study Completion Date: May 2005
Detailed Description:


  • Determine the maximum tolerated dose of polyglutamate camptothecin (CT-2106) in patients with advanced malignancies.
  • Determine the tolerability of this drug in these patients.
  • Determine the safety of this drug in these patients.
  • Determine the pharmacokinetics and pharmacodynamics of this drug in these patients.
  • Determine the disease response in patients treated with this drug.

OUTLINE: This is a dose-escalation, multicenter study.

Patients receive polyglutamate camptothecin (CT-2106) IV over 10 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients receive 2 additional courses beyond confirmation of complete response.

Cohorts of 3-6 patients receive escalating doses of CT-2106 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

Patients are followed at 3 weeks.

PROJECTED ACCRUAL: A total of 12-48 patients will be accrued for this study.
