Jon was selected to undergo a medical trial since the end of Nov 2015. Apparently he has achieved a complete molecular remission of his CML. Until now, no one is sure whether it is safe to take off Glivec completely. However, trial in a few countries found that patients on Pegasys (peginterferon alfa-2a) showed very encouraging result. Hence, he is now on a weekly injection of Pegasys instead of taking Glivec.
Since he is on Pegasys, he is also slowing gaining weight which is very encouraging.
Pray that he can be completely taken off Glivec.
