3 weeks of dosing where it was onve per week was nothing! The T1/2 (half life) is 2-3 hours so after 10 T1/2 (20-30hrs) its gone. A second dose a day or two later and its a SUPER 1-2 punch in phase II! This isfreaking outstanding news! Kevetrin is SAFE and EFFECTIVE against pancreatic cancer. This is a TERRIBLE disease and once diagnosed you only have a few months so for the patient to have a few extra months on such low doses is incredibly remarkable. To those assholes who will argue its not statistically powerful enough: go eat turds. That patient and their family would gladly serve them to you. And of course, multi-week dosing will smack some sense into you.
