Alternate Title

PI-88 in Treating Patients With an Advanced Malignancy (Cancer) or Stage IV Melanoma

Basic Trial Information

Phase Type Status Age Sponsor Protocol IDs Phase II, Phase I Treatment Closed 18 and over Pharmaceutical / Industry PROGEN-PR88201 COMIRB-01-207, NCT00073892

Objectives

Phase I

1. Determine the maximum tolerated dose of PI-88 in patients with an advanced malignancy.
2. Determine the safety and tolerability of this drug in these patients.

Phase II

1. Determine the progression-free survival and time to progression in patients with stage IV melanoma treated with this drug.
2. Determine the biological activity of this drug in these patients.

Expected Enrollment

A total of 18-69 patients (18-30 for phase I [part 1], 6-9 for phase I [part 2], and 25-30 for phase II) will be accrued for this study.

Outline

This is an open-label, dose-escalation study.

• Phase I (parts 1 and 2):
  • Part 1: Patients receive PI-88 subcutaneously (SC) once daily on days 1-4 and 15-18.

    Cohorts of 3-6 patients receive escalating doses of PI-88 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. Once the MTD has been determined in part I, the effect of dose frequency is determined in patients in part II.

  
  
  
  • Part 2: Patients receive PI-88 SC once daily on days 1-4, 8-11, 15-18, and 22-25 at a dose based on the MTD determined in part 1.

    Cohorts of 3 patients receive escalating doses of PI-88 until the MTD at this frequency is determined.

  
  
  



• Phase II (patients with metastatic melanoma): Patients receive PI-88 as in phase I, part 2 at the MTD.

Treatment in both phases repeats every 28 days in the absence of disease progression or unacceptable toxicity.
