The sponsor of the current study is now Acrotech Biopharma, divested from Spectrum Pharmaceuticals Inc. (Spectrum), which licensed the Melphalan HC1 for Injection (Propylene Glycol-Free) product from Ligand Pharmaceuticals , formerly CyDex Pharmaceuticals, Inc. (CyDex). This new injectable form of melphalan HCL incorporates Captisol®, β cyclodextrin sulfobutyl ether sodium salts (also known as [SBE]7m-β-CD), into the product. Captisol is present to facilitate the use of an all aqueous diluent (normal saline) for reconstitution and administration of the freeze-dried product in place of the propylene glycol-ethanol diluent necessary for the currently used melphalan intravenous product. Captisol provides for solubilization and improved stability of the all aqueous reconstituted and diluted infusion solution.~This is the second of two studies supporting product registration. This study will be a multicenter study of high-dose Melphalan HCL for Injection (Propylene Glycol-Free) conducted in 60 patients who have symptomatic MM and qualify for autologous stem cell transplantation (ASCT).~During the Study Period, patients will receive 100mg/m2 of either Melphalan HCL for Injection (Propylene Glycol-Free) on Day -3 and on Day -2 for a total dose of 200mg/m2. Blood samples (5 timepoints post infusion) for population pharmacokinetic (PK) evaluation will be withdrawn through an indwelling i.v. cannula on the first day of administration of melphalan (Day -3) for all patients and then additional blood samples (2 timepoints post infusion) drawn in a subset of patients on the second day of melphalan administration (Day -2).~Following one day of rest after the high dose myeloablative conditioning (Day -1), patients will receive an autologous graft (Day 0).
The purpose of this trial is to confirm the safety and efficacy of high-dose Melphalan HCL for Injection (Propylene Glycol-Free) as a myeloablative conditioning regimen in multiple myeloma patients (MM) undergoing autologous transplantation.
