Regorafenib With Temozolomide With or Without RT in MGMT-Methylated, IDH Wild-type GBM Patients (REGOMA-2)
Regorafenib in Combination With Temozolomide With or Without Radiotherapy in Patients With Newly Diagnosed MGMT-Methylated, IDH Wild-type Glioblastoma. A Phase I Dose-finding Study
This study will evaluate the addition of regorafenib to standard of care treatment with TMZ as adjuvant therapy, and in combination with TMZ+RT as concomitant therapy.
The standard of care for newly diagnosed GBM (ndGBM) includes surgical resection to the extent that is safely feasible, followed by RT plus concomitant TMZ chemotherapy, and up to 6 months of adjuvant TMZ.
The dose escalation will be explored following a "3+3" design, escalating oral doses of regorafenib in combination with adjuvant (maintenance) TMZ (cohort A) to estimate the MTD of regorafenib as adjuvant (maintenance) therapy. After finding the MTD in the Adjuvant Therapy dose escalation, the Concomitant Therapy (cohort B) dose escalation will start, exploring escalating oral doses of regorafenib in combination with concomitant TMZ+RT, to estimate the MTD of regorafenib as concomitant therapy.
