Vaccine Therapy in Treating Patients With Chronic Myelogenous Leukemia
RATIONALE: Vaccines may make the body build an immune response to kill cancer cells.
PURPOSE: Phase II trial to study the effectiveness of vaccine therapy in treating patients who have chronic myelogenous leukemia.
|Study Design:||Primary Purpose: Treatment|
|Official Title:||Phase II, Multicenter Vaccination of Patients With Chronic Myelogenous Leukemia With a Multivalent Tumor Specific Breakpoint Peptide Vaccine|
|Study Start Date:||March 1999|
|Study Completion Date:||August 2005|
|Primary Completion Date:||August 2005 (Final data collection date for primary outcome measure)|
- Determine the safety and immunogenicity of a multivalent tumor-specific breakpoint peptide vaccine in patients with chronic myelogenous leukemia.
- Determine the antileukemic effects of vaccination with these peptides in these patients.
OUTLINE: Patients receive bcr/abl breakpoint peptide vaccine in QS21 adjuvant subcutaneously at rotated sites every 1-3 weeks (on or about days 0, 7, 21, 35, and 56) over 8 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients demonstrating a response by week 10 may receive 3 additional monthly vaccinations initiated within 8 weeks of the fifth dose. Patients demonstrating a response by vaccination 8 may receive 3 additional vaccinations administered at two-month intervals.
Patients are followed at 2 weeks.
PROJECTED ACCRUAL: A total of 24 patients will be accrued for this study within 2 years.
