CpG 7909 in Treating Patients Who Have Undergone Autologous Stem Cell Transplant
|ClinicalTrials.gov Identifier: NCT00369291|
Recruitment Status : Terminated (Slow accrual)
First Posted : August 29, 2006
Last Update Posted : November 29, 2017
RATIONALE: Giving CpG 7909 after an autologous stem cell transplant may make a stronger immune response and prevent or delay the recurrence of cancer.
PURPOSE: This phase I trial is studying the side effects and best dose of CpG 7909 in treating patients who have undergone autologous stem cell transplant.
|Condition or disease||Intervention/treatment||Phase|
|Germ Cell Tumor Leukemia Lymphoma Multiple Myeloma and Plasma Cell Neoplasm||Biological: keyhole limpet hemocyanin Biological: tetanus toxoid||Phase 1|
- Determine whether CpG 7909 enhances immune function, as measured by the response to keyhole limpet hemocyanin (neo-antigen) and tetanus toxoid (memory antigen), in patients who have undergone autologous stem cell transplantation.
- Determine if dose escalation of CpG 7909, within a range of previously tested safe doses of CpG 7909, impacts upon the primary immune readouts.
OUTLINE: This is a non-randomized, dose-escalation study of CpG 7909.
Patients receive CpG 7909 subcutaneously (SC) on days 1, 7, and 14. Patients receive keyhole limpet hemocyanin SC and tetanus toxoid SC on day 7.
Cohorts of 3-6 patients receive escalating doses of Cp6 7909 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. A total of 10 patients are treated at the MTD.
Blood is collected at baseline and at approximately day 40 for immunological studies, including immunoenzyme techniques, antibody response assays, and immunophenotyping.
After completion of study treatment, patients are followed every 3 months for 1 year.
