IntroductionFor multiple myeloma patients who respond to primary therapy, autologous hematopoietic stem cell transplant (HSCT) is considered standard of care with high-dose melphalan for transplant candidates. There are now two different melphalan formulations available, including a propylene glycol containing (PG-MEL) product and a propylene glycol-free (PG-free MEL) product. Although considered bioequivalent, there remains limited literature directly evaluating the adverse events between the two agents. We seek to assess the tolerability and severity of side effects between the two formulations in a real-life practice setting.MethodsA retrospective, descriptive analysis was conducted of multiple myeloma patients who received autologous stem cell conditioning with either melphalan formulation when dosed at 100 mg/m2/dose for two consecutive doses. The primary outcome was the assessment of tolerability and severity of side effects. Tolerability was split into four major categories including hematologic to...
