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. SI-053 is a novel delivery format of temozolomide (gel format) directly administered at the site of the tumour following surgical removal, thus ensuring that the therapeutic effect is delivered precisely where it is needed and without the need to pass through the blood-brain barrier Temozolomide is a prodrug which destroys the tumour’s DNA and triggers the death of tumour cells.
