You really need to check yourself what medicine will work for CLL. I believe that there is no such thing as IMITINEF MERCILET
There is a medcine in the market called IMATINIB ( GLIVEC) made by Novartis they also make a next ggeneration of medicine called NILOTINIB
(TASIGNA) which is used to continue if the patient is intolerant to IMATINIB.
There is also another one called DASATINIB
(SPRYCEL) made by Bristol Myer Squibb which is very effective and sits between the two above
Please check them out on the net or contact Hammersmith Hospital in London on 0044 8383 4340 to contact Proffessor Apperley or Dr David Marin. This hospital is world renoun for all types of Leukimea treatments.
I hope this helps in search for your fathers treatment
