Discharge from trial

My father has been discharge from the clinical trial medicine. There has been no improvement to his condition and the tumour size is still about the same as previously. The trial medicine dosage has been reducing as my father complain about fatigue and pain.
The doctor has advised that we can either stop the treatment or try the chemotherapy. But he do not think the chemotherapy will help in this case. In other words, he meant to let the patient enjoy life. So the doctor is also powerless against this cancer and it is now up to the patient will power to fight the battle. Abbott ABT 869 trial medicine has finally still not help to win the cancel battle.
