Detection of erythropoiesis stimulating agent Luspatercept after administration to healthy volunteers for antidoping purposes.

ABSTRACT: Luspatercept (Reblozyl®) is a newly approved anti-anemic drug prohibited by the World Anti-Doping Agency. It promotes erythropoiesis by limiting apoptosis of immature erythroblasts and the risk of misuse by athletes for doping is high. Proposed detection methods have been published recently but only evaluated in vitro. The objective of this study was to perform the first administration of luspatercept in healthy volunteers for antidoping purpose and to evaluate the detectability in serum, dried capillary blood spots (DBS, collected using TASSO M20 device), and urine. Indirect detection was also evaluated by analyzing hematological parameters for the Athlete Biological Passport. Four volunteers (two males, two females) received one subtherapeutic dose of luspatercept (0.25 mg/kg) followed 3
