Yes Gary, this paxalisib, a PI3 cell disorder inhibitor, developed to treat cancer and kind of gave up by Genentech is now being tested by Karzia, and like you said the benefit is when compared with DcVaxL is like between a valley and Himalayas. But I see Karzia is gaining traction for a few month improvement shown in Phase 2. A few months Vs a few years, I think DcVax is unbeatable by any pharma including BPs. We are golden, just can't wait for TLD! Go NWBO!!
