I was in a trial testing Stivarga for other cancer types as it is currently on the market for colo-intestinal types. You had to have a certain mutation to be in the trial and I did. The first cycle was at full strength (4 pills a day) and the second cycle was at 75% strength (3 pills a day). It did a great job and shrank my primary tumor from greater than 13 x 8.9 centimeters to 8 x 7.1 centimers and also shrank the metastatic tumors some. However, it is almost debilitating at that strength as it affects the hands, feet, and mouth. But I stayed on it at 50% strength for 10 more cycles with continued mild shrinkage before the cancer started winning again. The last good scan showed the primary tumor at 7.7 x 3.9 centimeters and it was a lymph node that kicked me out of the trial.
I just did 2 cycles of PEN-866 but that was a bust for me. Might work for someone else though. I am now waiting to see where I can be a guinea pig next.
P.S. Diagnosis was in March of 2017 and I did two cycles of the gem/cis. Everything grew. I started the Stivarga trial in June of 2017 and failed out in May of 2018.
