I have MDS RARS, SF3B1 mutation Dx in 2006. I have been on Luspatercept since April. I had a lot of side effects at first, dizziness, bone pain, diarrhea, all have subsided except the diarrhea after 12 injections. My WBC’s and Platelets improved first, and just recently, my HGB was 10.6 which is a number I haven’t seen in over 5 years. I still get transfused every two weeks, but only one unit instead of two. Hoping to stretch it out to every 3 weeks, but we’ll see.
So, please don’t despair if it is not working for you after 5 weeks, my Hematologist who is familiar with the clinical trials told me it can take many months to work.
