Patients received carfilzomib at a dose of 15 or 20 mg/m2 on days 1 and 2 and a target dose of 56 or 20 mg/m2 on days 8, 9, 15 and 16 in trials PX‐171‐007 and PX‐171‐005, respectively. Some patients in PX‐171‐005 did not step up to their target dose (e.g. from 15 to 20 mg/m2) and continued to receive 15 mg/m2. Patient responses were determined using International Myeloma Working Group criteria (Badros et al, 2013; Papadopoulos et al, 2013).
