Trial of Newly Diagnosed High Grade Glioma Treated With Concurrent Radiation Therapy, Temozolomide and BMX-001 — BMX-HGG  

Glioblastoma Clinical Trial

Official title: A Phase 2 Trial for Patients With Newly Diagnosed High Grade Glioma Treated With Concurrent Radiation Therapy, Temozolomide, and BMX-001

Status Active, not recruiting

Clinical Trial Summary

This is a Phase 2 study of newly diagnosed patients with high grade glioma (HGG) undergoing standard radiation therapy and temozolomide treatment. BMX-001 added to radiation therapy and temozolomide has the potential not only to benefit the survival of high grade glioma patients but also to protect against deterioration of cognition and impairment of quality of life. BMX-001 will be given subcutaneously first with a loading dose zero to four days prior to the start of chemoradiation and followed by twice a week doses at one-half of the loading dose for the duration of radiation therapy plus two weeks. Both safety and efficacy of BMX-001 will be evaluated. Impact on cognition will also be assessed. Eighty patients will be randomized to the treatment arm that will receive BMX-001 while undergoing chemoradiation and 80 patients randomized to receive chemoradiation alone. The sponsor hypothesizes that BMX-001 when added to standard radiation therapy and temozolomide will be safe at pharmacologically relevant doses in patients with newly diagnosed high grade glioma. The sponsor also hypothesizes that the addition of BMX-001 will positively impact the overall survival and improve objective measures of cognition in newly diagnosed high grade glioma patients.

Clinical Trial Description

160 patients will be enrolled and randomized with a treatment arm allocation ratio of 1:1 in the Phase 2 study. At enrollment, patients will be assessed with medical history, physical/neurological examinations, standard laboratory evaluations (CBC with differential and comprehensive metabolic panel (CMP)), baseline brain MRI with and without gadolinium, cognitive testing and patient-reported outcome questionnaires of HRQoL. On the first day of BMX-001 (loading dose), patients will be evaluated with medical history, patient physical/neurological examinations, and standard laboratory evaluations (CBC with differential and CMP), and ECG. Patients in Arm A will be administered BMX-001 subcutaneously first as a loading dose before the start of chemoradiation and then at maintenance dose (50% of the loading dose) twice a week for 8 weeks. Because oxidative stress continues to occur for up to several weeks following RT, the proposed protocol includes administering BMX-001 both before the start of RT and continuing for 2 weeks after the completion of RT and TMZ. TMZ will be dosed at 75 mg/m2 orally daily for 42 days and RT will be delivered in daily fractions of 1.8-2 Gy given 5 days a week for 6 weeks for a total of 59.4-60 Gy. During standard RT and TMZ, CBC with differential and CMP will be obtained weekly. Two weeks after the completion of standard RT and TMZ and every 8 weeks during adjuvant TMZ, patients will be evaluated with the following: medical history, physical/neurological examinations, Brain MRI with and without gadolinium, cognitive testing and patient-reported outcome questionnaires of HRQoL. Two weeks after the completion of chemoradiation, patients will transition to adjuvant chemotherapy with TMZ dosed at 150-200 mg/m2 orally for 5 days of a 28-day cycle for a total of 12 cycles. In light of the findings that BMX-001 can spare radiation-induced hair loss in a mouse model [41], we will evaluate and describe hair loss as an exploratory outcome in HGG patients by evaluating hair at baseline and then every 8 weeks. Patients will be discontinued from the study if they experience progression of disease, death or withdraw informed consent. ;
