Details and patient eligibility

About

This is a multicenter, Phase 2, Proof-of-concept study in subjects with newly diagnosed glioblastoma multiforme (GBM).

All subjects will receive standard of care therapy for the treatment of their GBM and any Anti-Epileptic Drug (AED) deemed necessary for their surgical resection of the GBM. Patients who are taking concomitant AEDs will be eligible for the study. Treatment with Anhydrous Enol-Oxaloacetate will be added to the Standard of Care.

This study is testing adjuvant Anhydrous Enol-Oxaloacetate (AEO) in GBM, an orally active drug candidate which in animal studies has demonstrated decreased tumor growth rate and increased survival.

Full description

Currently, the multidisciplinary Standard of Care treatment for Glioblastoma multiforme includes maximal surgical resection of the tumor followed by radiotherapy plus concomitant and maintenance temozolomide chemotherapy.This study will treat newly diagnosed GBM patients by adding Anhydrous Enol-Oxaloacetate treatment to their current Standard of Care.

In the body, Anhydrous Enol-Oxaloacetate (AEO) converts into "Oxaloacetate", a metabolite important for many biochemical reactions in the body. On a cellular level, oxaloacetate treatment has been found to modify cancer metabolism in GBM cells, reversing the "Warburg Effect", reducing glycolysis and reducing lactate production. In animals, oxaloacetate treatment has increased survival and reduced tumor growth of implanted GBM tumors.

In other animal studies, oxaloacetate has also shown to have neuo-protective effects including positive effects on seizure development.
