Pentostatin in Treating Patients With Refractory Chronic Graft-Versus-Host Disease
RATIONALE: Pentostatin may be effective in treating chronic graft-versus-host disease by stopping the immune system from rejecting donor stem cells or donor white blood cells.
PURPOSE: This phase II trial is studying how well pentostatin works in treating patients with chronic graft-versus-host disease that is refractory (not responsive) to treatment with steroids.
|Study Design:||Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Supportive Care
|Official Title:||A Phase II Trial Of Intravenous Pentostatin For The Treatment Of Patients With Refractory Chronic Graft-Versus-Host Disease|
- Response Rate [ Time Frame: 3 months ]
Percentage of participants who had a complete or partial response defined by the Hopkins scoring system.
A complete response is defined as the disappearance of signs and symptoms of chronic GVHD in all involved systems that is sustained for at lest 4 weeks. A partial response is an improvement by 2 or more points in at least one system score, which is sustained for at least 4 weeks, with no signs of worsening in others.
- Grade 3 or Higher Non-hematologic Adverse Events [ Time Frame: Duration of treatment (up to 5 years) ]Number of participants experiencing a grade 3, 4 or 5 clinically significant non-hematologic adverse events, at least possibly related to treatment.
- Overall Survival At 1 Year [ Time Frame: 1 year ]Percentage of patients who were alive at 1 year.
- Overall Survival At 2 Years [ Time Frame: 2 year ]Percentage of patients who were alive at 2 years.
- Pharmacokinetics [ Time Frame: At initiation of Tx and at 3 months ]
|Study Start Date:||December 2003|
|Primary Completion Date:||August 2008 (Final data collection date for primary outcome measure)|
treatment of pts with refractory graft vs host disease
4 mg/sq m IV infusion over 20-30 min q 2 weeks
- Determine the response rate in patients with refractory chronic graft-versus-host disease treated with pentostatin.
- Determine the time to next immunosuppressive agent (i.e., the time to progression from best response) in patients treated with this drug.
- Determine the toxicity of this drug in these patients.
- Determine the infection rate in patients treated with this drug.
- Determine the pharmacokinetics of this drug in these patients.
- Determine the changes in lymphocyte populations in patients treated with this drug.
- Determine the survival of patients treated with this drug.
OUTLINE: This is a multicenter study.
Patients receive pentostatin IV over 20-30 minutes on day 1. Treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity.
Patients who achieve a complete response after 6 courses receive 4 additional courses. Patients who achieve a partial response, minor response, or stable disease after 6 courses may receive up to 6 additional courses.
Patients are followed every 4 weeks for 1 year, every 3 months for 2 years, and then annually for 5 years.
PROJECTED ACCRUAL: Approximately 37 patients will be accrued for this study.
