Approximately 188,000 new cases of HGG are expected to be diagnosed this year across the globe.
HGG reappears in most patients after frontline treatment, and standard of care treatment usually offers an average survival of only seven to nine months.
Tocagen CEO Marty Duvall said: “Completing enrolment in Toca 5 is the latest example of our recent progress as we continue to execute against our goals.
“This important milestone also triggers the next milestone payment of $2m from ApolloBio, our licensor of Toca 511 & Toca FC within the greater China region.”
