Hi @estrada53, our nurse coordinator mentioned this new drug, Levtincity better known as Maribivar. She suggested to to the provider that is an alternative to Valcyte because the new drug does NOT deplete WBCs. A few of the Mayo patients have had very successful outcome with it, according to nurse. At this time however, the provider is sticking with Valcyte but we are more than ready to try the new drug. One draw back about Maribivar is that it is extremely expensive and our insurance requires prior authorization. Thanks for chiming in.estrada53 w drug, Levtincity better known as Maribivar.
