Melphalan (Alkeran) is an FDA-approved low-dose chemotherapy for multiple myeloma marketed by GlaxoSmithKline. A phase II(a) trial that compares the pharmacokinetics and safety of CDX-353 with Alkeran is planned. Alkeran is packaged as two vials that must be combined prior to injection and requires immediate administration. CDX-353 is a one-vial formulation that remains stable at room temperature for an extended period of time, according to CyDex.
