About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RegorafenibDrug
Cohort A (Adjuvant/Maintenance Phase). The Adjuvant (Maintenance) Therapy dose escalation will explore three dose levels of regorafenib (e.g., 80 mg, 120 mg and 160 mg; level-1: regorafenib 40 mg will be evaluated in case of DLT during regorafenib 80 mg) administered in combination with adjuvant TMZ to evaluate the initial toxicity of regorafenib and TMZ Cohort B (Concomitant Phase) Therapy dose escalation will explore three dose levels of regorafenib (e.g., 80 mg, 120 mg and 160 mg; level -1: regorafenib 40 mg will be evaluated in case of DLT during regorafenib 80 mg) administered in combination with TMZ and RT.
TemozolomideDrug
Following a "3+3" design, in cohort A three patients will be administered temozolomide 150-200 mg/m2 for 5 consecutive days every 28 days until 6-12 cycles and regorafenib daily for 21 days, with a 1-week washout period at dose of 80 mg (level 1), 120 mg (level 2), or 160 mg (level 3) (regorafenib 40 mg- level -1). As a general rule, one cycle will last 28 days (day 1-28); however, in the event of treatment prolongation, the cycle period will be extended.
In cohort B,During concomitant therapy phase: temozolomide 75 mg/m2/die for 42 (max 49 days) consecutive days (concomitant with radiation therapy).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Regorafenib and Temozolomide in people with Glioblastoma, IDH-wildtype and MGMT-Methylated Glioblastoma, run by Istituto Oncologico Veneto IRCCS at 2 sites in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 29 inclusion and 29 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with a Dose Limiting Toxicity (DLT) (time frame: During dose escalation, the DLT evaluation period will be two cycles from Day -1 of Cycle 1 of adjuvant phase (cohort A) or from Day 1 to last day of the concomitant RT phase (Cohort B). (each cycle is 28 days)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2026.
