Been reading about lower dosages of TKI drugs, especially Sprycel, but couldn't find much on those taking Tasigna. Also anyone taking Tasigna along with Neupogen shots to keep WBC and ANC up out of danger zone? Would be interested in hearing about everyone's experiences with either of these questions. Thanks so much to all that contribute on this forum. Can't tell you how uplifting it is to be empoewered with some knowledge from other people dealing with the same diease.
Anyone acheiving good response while on lower dosage of Tasigna?

mbrown,
In one three month period, I went from 0.2% PCR to .001% PCR averaging 300 mg Tasigna daily. Not a huge achievement as far as log reductions go, but my doctor was very happy, grinning in fact, and so was I... as that was all i could manage during that time period of added stressors in my life. I believe lower doses are entirely possible. I feel empowered too by hearing what works for other people. I continue to strive to take the higher dose, but I do what I can. Janne
Dx'd: 8/2008. Started Gleevec 400 mg 11/08.
Drug break 2011.
Started Tasigna 4/11 450 mg.
Reduction to 300 mg Tasigna 1/2012.
PCRU 9/2012.
12/2012 Detectable.
PCRU 4/2013 through 3/2015. (Reduced to 150 mg 7/2014)
12/2015 ? slightly detectable at probably less than 0.01% per Mayo Clinic.
4/2016 PCRU. Still at 150 mg Tasigna.
CESSATION: stopped treatment 7/20/2017.
9/6/2017: barely detectable at 0.01%.
12/11/2017: PCR at 0.09% (did not do the monthly PCR testing.)
12/18/2017: Inevitable call from Onc. Started back on Tasigna at 150 mg. (Considering Sprycel low dose.)

Thanks Janne for sharing. I too feel that for some people lower than "standard" dosage will work. Just like some people can't tolerate full strength doses of other meds, yet they acheive the same effect as if they did take a full dose. I can't help but think that a person's metabolism and body mass should play a part in what their dose should be and still manage positive response with less side effects. I have yet to be able to tolerate a "full" dose of any of the 3 TKIs available, though it remains a goal. I was dx in May 2011 and still have not acheived CHR mainly due to myloid suppression. I'm now trying the neupogen shots and 1/2 dose of Tasigna. Time will tell...
