Tofacitinib in Recurrent GBM Patients

Inclusion criteria

• . Histologically confirmed GBM (MGMT unmethylated, IDH wild type) at first, second, third, or fourth recurrence after concurrent chemoradiotherapy. Patients with an initial diagnosis of a lower-grade glioma are eligible if a subsequent biopsy determined the progressive tumor to be GBM.
• . Imaging confirmation of first tumor progression or regrowth as defined by the Response Assessment in Neuro-Oncology (RANO) criteria. A minimum of 12 weeks must have elapsed from the completion of radiotherapy to study entry to minimize the potential for MRI changes related to radiation necrosis that might be misdiagnosed as progression of disease, unless there is a new lesion outside the radiation field or unequivocal evidence of viable tumor on histopathological sampling.
• . Karnofsky Performance Status (KPS) ≥ 60%.
• . Patients must be willing and able to provide written informed consent and to comply with the study protocol as judged by the investigator.
• . Age ≥ 18 years.
• . Patients must be able to swallow oral medications.
• . For women who are of child-bearing potential and who are sexually active and who are not surgically sterile (absence of ovaries and/or uterus): to use an adequate method of contraception (oral contraceptives, intrauterine contraceptive device, barrier method of contraception in conjunction with spermicidal jelly) during the treatment period and for at least 6 months after last dose of study drug. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. For male patients who are partners of premenopausal women: agreement to use a barrier method of contraception during the treatment period and for at least 6 months after the last dose of study drug.
