Carfilzomib and PX-171-004
• Carfilzomib is a selective tetrapeptide epoxyketone proteasome inhibitor that displays potent and sustained proteasome inhibition.
• The high degree of selectivity of carfilzomib may account for its improved tolerability profile: – In early clinical studies, carfilzomib has not been associated with
dose-limiting peripheral neuropathy (PN).
• PX-171-004 is an ongoing multicenter, non-randomized, open-label, single-arm phase 2 trial of single-agent carfilzomib in patients with R/R MM who have received 1–3 prior lines of therapy.

Study Design and Treatment
• Bortezomib-naïve patients (N=129) were enrolled in 2 sequential dose cohorts.
– In Cohort 1, patients received carfilzomib 20 mg/m2 IV on Days 1, 2, 8, 9, 15, and 16 every 28 days, for up to 12 cycles.
– In Cohort 2, patients received a stepped-up, dose-escalating regimen of carfilzomib 20 mg/m2 for Cycle 1 followed by carfilzomib 27 mg/m2 for all subsequent treatment cycles.
– Dexamethasone 4 mg was administered prior to carfilzomib in Cycle 1 only to ameliorate a potential “first dose” effect (including fever, chills, rigors, and dyspnea).
• Patients completing all 12 cycles were eligible to enroll in an extension study (PX-171-010).

Similar Incidence and Severity of AEs Between Cohorts
• There were no discontinuations of treatment due to peripheral neuropathy.
• In no case were any toxicities (any grades) >2% higher in Cohort 2 than in Cohort 1; in general they were either similar or lower
• cumulative toxicities has been observed in patients continuing on extended carfilzomib treatment (PX-171-010).
