Selinexor is an interesting drug with a different mechanism of action. At the initial evaluation of the drug, where it was given as monotherapy with low dose dexamethasone, the high doses given on two consecutive days were associated with excessive gastrointestinal toxicity, asthenia, loss of appetite and essentially this precluded many patients for getting the drug. However, more recently selinexor is being used at lower doses, starting maybe at 40mg weekly in combination with bortezomib in the context of SVd regimen...
Selinexor is an interesting drug with a different mechanism of action. At the initial evaluation of the drug, where it was given as monotherapy with low dose dexamethasone, the high doses given on two consecutive days were associated with excessive gastrointestinal toxicity, asthenia, loss of appetite and essentially this precluded many patients for getting the drug. However, more recently selinexor is being used at lower doses, starting maybe at 40mg weekly in combination with bortezomib in the context of SVd regimen. And this SVd combination is an active and relatively well tolerated combination that could be used for patients who are being treated previously with lenalidomide, even with anti-CD38 monoclonal antibodies, and when access to clinical trials or to other drugs is limited.
