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
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.
