About this study

Official title: Efficacy and Safety of Low Dose Temozolomide Plus Metformin as Combination Chemotherapy Compared With Low Dose Temozolomide Plus Placebo in Patient With Recurrent or Refractory Glioblastoma

A phase 2 clinical trial for the efficacy and safety of low dose Temozolomide plus metformin as combination chemotherapy compared with low dose Temozolomide plus placebo in patient with recurrent or refractory Glioblastoma

Read the detailed description

Studies will investigate the efficacy and safety of low dose Temozolomide with Metformin or placebo for the patients with recurrent or refractory Glioblastoma.

The dosage of the Metformin will follow the domestically permitted dose to minimize side effects.

The patients will be allocated randomly to arm 1(experimental) and arm 2(placebo controlled) and administered the investigational products for up to 6 cycle. Each cycle consists of 4 weeks.

After 6 cycle(24 weeks), the patients will be checked progression and survival every 24 weeks up to 96 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Temozolomide+Metformin in people with Glioblastoma, run by Yong-Kil Hong at 12 sites in South Korea.

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 11 inclusion and 14 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 9 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in South Korea. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Comparison of progression-free survival obtained from progression-free survival curve (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03243851, which also lists 1 linked publication.

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 9 Sep 2021.
