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. K Stewart et al ASCO Abstract 8026
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). K Stewart et al ASCO Abstract 8026
Significant Responses‡in BTZ-naïve Patients • Significant response rates were observed in both cohorts *Data cut-off date 9 February 2011 †2 patients (3%) in Cohort 2 were excluded on the basis of missing baseline or post-baseline disease assessments. ‡Responses confirmed by Independent Review Committee ORR= 42% ORR= 51% CBR= 59% CBR= 63% K Stewart et al ASCO Abstract 8026
Substantial Duration of Response Observed for Cohorts 1 and 2* K Stewart et al ASCO Abstract 8026 *Data cut-off date 9 February 2011
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).
