Treatments for Relapsed and Refractory Multiple Myeloma - Episode 4
Ravi Vij, MD:The patient in this illustration is between 70 and 80 years of age. Most of the patients in my practice, between 70 and 80, who are not transplant-eligible, are able to tolerate a 3-drug regimen. I think that in my own practice, therefore, I would probablyas noted before—have treated this patient with a 3-drug regimen of bortezomib (Velcade), lenalidomide (Revlimid), and dexamethasone because I believe that it produces greater depth of response, which usually leads to long-term outcomes being better.
In the patient who is not transplant-eligible, we don’t have any data on VRD-lite. We do, however, have data from patients who are not proceeding on to stem cell transplant, with full intensity regimen of Velcade, Revlimid, and Decadron (dexamethasone), actually improved survival over the use of Revlimid and Decadron, in a study conducted by SWOG.
Certainly, that population of patients included some that were possibly transplant-eligible. They were just not meant to be taken to transplant right away. With that piece of information, though, I am more inclined to use a 3-drug regimen if possible, because we have not only a progression-free survival but also an overall survival benefit, albeit with full intensityVelcade, Revlimid, and Decadron.
The question of whether bortezomib use is difficult in patients who have preexisting neuropathy comes up frequently. In the elderly, it is even more of a relevant factor to take into consideration before deciding therapy. There are patients who have diabetic neuropathy and that, again, can be a contraindication to using bortezomib. The use of bortezomib given subcutaneously these days, and given only once a week, has certainly reduced the intensity and the kind of neuropathy that we used to see in the past. However, by no means has it eliminated it. So, we are trying to avoidespecially in those who have preexisting neuropathy—the use of bortezomib frontline. However, there’s no absolute contraindication that I see in this case to the possible use of bortezomib.
