- Radiation: Radiation therapyProcedure: Stem cell collectionProcedure: Stem cell infusion
- Registration Number
- NCT02976441
- Lead Sponsor
- Washington University School of Medicine
- Brief Summary
The investigators hypothesize that this study will show that sufficient lymphocyte stem cell can be harvested prior chemoradiation and be reinfused back after treatment, and at least 5 of the 10 patients (50%) will achieve an absolute increase of lymphocyte counts of 300 cells/mm\^3 four weeks after stem cell reinfusion in high grade glioma patients.

- Primary Outcome Measures
Name Time Method Efficacy of lymphocyte stem cell harvesting and reinfusion in patients as measured by the number of patients from whom 1-5x10e6 lymphocyte stem cells are collected and successfully reinfused without an adverse event Completion of follow-up of all patients who received stem cell reinfusions (estimated to be 15 months) The study will provide preliminary evidence of efficacy if ≥5 of 10 patients (50%) achieve an increase over baseline in absolute lymphocyte counts (ALC) ≥300 cells/mm3 at 4 weeks after reinfusion from their baseline lymphocyte counts.
- Secondary Outcome Measures
Name Time Method Safety and toxicities with stem cell collection and reinfusion as measured by grade and frequency of adverse events Up to 6 months after stem cell reinfusion (approximately 9 months) the descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all adverse event/toxicity reporting.
Changes in lymphocyte subtypes following collection and reinfusion Up to 6 months after stem cell reinfusion (approximately 9 months) Lymphocyte subtypes will be monitored by flow cytometry at the time of stem cell collection, prior to autologous stem cell reinfusion, and then monthly for 6 months.
Changes in series of cytokine levels following collection and reinfusion Up to 6 months after stem cell reinfusion (approximately 9 months) Cytokine levels will be checked by ELISPOT at the time of stem cell collection, weekly during radiation therapy/temozolomide (up to 6 weeks), prior to autologous stem cell reinfusion, and then monthly for 6 months.
Number of lymphocyte stem cells that can be harvested from this patient population Completion of follow-up of all patients who received stem cell reinfusions (estimated to be 15 months) Proportion of patients who have an increase in lymphocyte of ≥300 cells/mm^3 after autologous stem cell reinfusion. 4 weeks after stem cell reinfusion Duration of lymphocyte rise following stem cell reinfusion Up to 6 months after stem cell reinfusion (approximately 9 months)
