Ravi Vij, MD:The use of ixazomib/lenalidomide (Ninlaro/Revlimid), and dexamethasone is also supported by the tolerability of the regimen in older individuals. The drug has good oral tolerability. Ixazomib is a drug that causes, in some patients, nausea, but the fact is, that if you take preventive measures, generally the side effect is mild. It is rare in my practice to see patients who have repeated episodes of emesis, requiring us to stop the drug. The other thing is that the drug, though associated with some neuropathy, is also much less than what we have seen with drugs like bortezomib (Velcade) in the past. The effect on the hematopoietic system certainly is there, but the fact is that once again, the effect on platelets especially is cyclical and manageable. So, overall, the drug regimen is well tolerated.
Another thing that we see sometimes with ixazomib is the development of a rash. Sometimes it’s difficult to know whether the rash happened because of lenalidomide, if used in the regimen, or ixazomib. There are truly some patients that have ixazomib-induced rashes, but fortunately they’re rare. One knows that one has to be cautious when we use any drug, but ixazomib, I think in the spectrum of tolerability, is toward the more favorable end of that spectrum.
What take-home would I deliver to people who are looking at possibly using ixazomib with lenalidomide and dexamethasone? I would say that the regimen is convenient. It is effective even for a high-risk subgroup of patients. It is a regimen that is well tolerated, and it is a regimen that I think, in the appropriate patient, pays dividends.
