Pharmacodynamic characteristics of velkeid efficacy in resistant and recurrent multiple myeloma: determination of free light chains of blood serum immunoglobulins


Aim. To ascertain individual sensitivity to veikeid in patients with resistant and recurrent multiple myeloma (MM) by determination of free light chains (FLC) of serum immunoglobulins.
Material and methods. Forteen patients with MM stage III (Gcappa-5, Glambda-2, Acappa-3, Alambda-1, BJcappa-3) aged 52-75 years with documented resistance to treatment or recurrence received second-line monotherapy with velkeid. The drug was injected intravenously (jet) in a dose 1.3 mg/m2 on the treatment day 1, 4, 8 and 11. Free light chains concentration was examined with antibodies to their latent determinants (Binding Site, UK) on nephelometer (Hitathi-911, Japan) on velkeid treatment day 1, 2, 3, 5, 9 and 12.
Results. Nine patients showed lowering of FLC concentration and responded to treatment by Durie criteria.
Conclusion. Dynamic follow-up of FLC concentration of the tumor clone in resistant and recurrent MM evaluates pharmacodynamics of the drug. The method provides prognosis of late clinical results.
