Glioblastoma is the most aggressive type of primary brain cancer, one with a prognosis of 11-15 months with standard treatment. Results from a phase 1b clinical trial of a new experimental glioblastoma vaccine developed by Jefferson and Imvax, show the treatment was tolerated well by patients, slowed tumor recurrence, and prolonged patient survival.
The research was presented at an oral session of the American Association for Cancer Research (AACR) annual meeting on March 31st in Atlanta, Georgia.
Researchers treated 33 patients with newly diagnosed glioblastoma multiforme with the novel cancer vaccine (IGV-001) in a prospective phase 1b clinical study and compared outcomes to a historical comparator group of 35 patients treated with standard of care at the same institution. The results showed patients treated with the vaccine had improved progression-free survival and overall survival compared to the control group treated with standard of care alone.
