Abstract 5132


PROSELICA (NCT01308580) assessed the non-inferiority of cabazitaxel 20 mg/m2 (C20) vs 25 mg/m2 (C25) in patients (pts) with mCRPC post docetaxel, while FIRSTANA (NCT01308567) investigated whether C20 and C25 were superior to docetaxel 75 mg/m2 (D75) in chemotherapy-naive mCRPC. This analysis evaluated the impact of cabazitaxel on HRQL in both trials.


Alongside pain and analgesic score, HRQL was assessed using the Functional Assessment of Cancer Therapy Prostate (FACT-P) questionnaire. The analysis focused on FACT-P (clinically meaningful improvement or deterioration of total score [TS]) among responders.


Pt baseline characteristics are shown in the table. In PROSELICA, 57.2% and 59.4% of pts receiving C20 and C25 had FACT-P TS improvements; in FIRSTANA, 63.5%, 62.3% and 57.7% of pts receiving C20, C25 and D75 had FACT-P TS improvements. In FACT-P responders, FACT-P TS improvements occurred as early as Cycle (C) 1 (mean change from baseline: PROSELICA C20 10.4, n = 264; C25 10.6, n = 266; FIRSTANA C20 11.7, n = 206; C25 11.7, n = 202; D75 9.0, n = 195); these were largely maintained. For pts with a pain response in PROSELICA, FACT-P TS improvements occurred as early as C1 (C20 6.8, n = 71; C25 11.1, n = 81) and were maintained until C8 (C20 10.6, n = 43; C25 9.6, n = 44). In FIRSTANA, FACT-P TS improvements in pts with a pain response were seen as early as C1 or C2 (C1: C20 15.5, n = 41; C25 12.5, n = 41; D75, 7.9, n = 32) and maintained until C9 (C20 9.0, n = 27; C25 10.5, n = 26; D75 16.4, n = 20). In pts with a tumor or PSA response, HRQL was maintained for all treatment arms in both studies. Additional results for clinical responder subgroups and FACT-P subscales will be presented.Table: 812P
