More about Glioblastoma: Glioblastoma, the most common and aggressive malignant form of all primary brain tumours, affects glial cells and accounts for 52 % of all brain tissue tumour cases and 20 % of all tumours inside the skull.  Approximately 12,000 patients with glioblastomas are identified each year in the US and 250 000 globally.

The current standard of care is surgery followed by radiation and chemotherapy. Double Bond’s Temodex®/SI-053 (Temozolomide) is a chemotherapy drug administered directly at the site of the tumour following surgical removal, in the form of a gel, thus ensuring that the therapeutic effect is felt precisely where it is needed. Temozolomide is a prodrug which destroys the tumour’s DNA and triggers the death of tumour cells.

DBP is managing an Early Access to Treatment program to raise awareness of the treatment’s availability to physicians and patients across the globe:
