Once consented and registered, eligible patients will commence Cycle 1 and be assessed on Cycle 1 Day 1. An entire cycle will be 28 days of continuous Tofacitinib dosing. There will be a gap of 18-24 days between the first and subsequent cycles of treatment. The patient will once again be assessed on Cycle 2 Day 1. An interim follow-up will be done after the second cycle, during which the patient will undergo a brain MRI for tumor measurements along with all other assessments. Subsequent cycles will continue as prior, with subject assessments, brain MRI, and toxicity evaluations every 4 weeks. Treatments will stop upon evidence of disease progression, unacceptable toxicity, or if the physician deems it unsafe for the subject to continue in the study.
The purpose of this study is to examine the effects of Tofacitinib in patients with recurrent Glioblastoma.
