Abstract:
242 Background: Cbz is an established second-line treatment for pts with mCRPC, having demonstrated an overall survival benefit (with P) vs mitoxantrone with P in the Phase III TROPIC trial. The global CUP (CABAZ_C_05005) and EAP (NCT01254279) (both funded by Sanofi) aimed to provide access to Cbz + P before commercial availability and to document safety in a real-world population. We present a regional analysis of interim data from the CUP and EAP. Methods: Expected total enrolment is 1,450 pts. Pts received Cbz 25 mg/m 2 IV Q3W + P 10 mg QD until disease progression (PD), death, unacceptable toxicity or physician/pt decision. Granulocyte colony-stimulating factor (G-CSF) was administered per ASCO guidelines. The cut-off date for this analysis was 30 May 2012. Results: Globally, 1,301 pts have been included from eight regions (Eastern Europe [EE], Western Europe [WE] , Northern Europe [NE] and Southern Europe [SE] ; Asia [As]; Canada [Ca] ; Latin America [LA]; and Australia [Aus] ). Key data by region are shown in the Table. Median age varied from 65 years (Ca) to 70 years (Aus, LA, SE). In pts who progressed after last D line, time from last D dose to last PD ranged from 2.3 months (EE, LA) to 6.6 months (Ca). G-CSF use (therapeutic or prophylactic) at Cycle 1 varied widely between regions, from 23% (WE) to 79% (As). Between 11% (LA) and 30% (NE) of patients received ≥10 cycles of Cbz. Conclusions: In this extensive, real-world CUP/EAP cohort of mCRPC pts, substantial regional variation was observed for baseline and on-treatment parameters, including time from last D dose to last PD and G-CSF use. The low proportion of patients receiving ≥10 cycles in LA, Ca and WE may result from a limit of 10 cycles of therapy in some centers. Clinical trial information: NCT01254279. [Table: see text]
