To assess the correlation between PFS2 and OS among patients with advanced prostate cancer (PC) in a real-world setting for Japan. This was a retrospective analysis using the Japanese MDV database. Patients with nmCRPC (non-metastatic Castration-Resistant PC), mCRPC (metastatic Castration-Resistant PC), and mCNPC (metastatic Castration-Naïve PC) were identified and their medical records were investigated for PFS2 and death. Association between PFS2 and OS was determined using the Pearson's, Spearman's, Kendall's Tau, and Fleischers' correlation coefficients. A total of 386,484 patients with PC were identified from the database, of which, 1,783 patients with nmCRPC, 630 with mCRPC, and 454 with mCNPC met the predefined eligibility criteria. Significant correlation between PFS2 and OS was observed in patients with nmCRPC (Pearson's r = 0.873; 95% CI: 0.849−0.897, Spearman's r = 0.909; 95% CI: 0.893−0.925; Kendall's Tau r = 0.831; 95% CI: 0.812−0.850, Fleischers' r = 0.682; 95% CI: 0.601−0.764), mCRPC (Pearson's r = 0.812; 95% CI: 0.758−0.865, Spearman's r = 0.895; 95% CI: 0.868−0.923, Kendall's Tau r = 0.789; 95% CI: 0.755−0.823, Fleischers' r= 0.439; 95% CI: 0.334−0.544), and mCNPC (Pearson's r = 0.931; 95% CI: 0.899−0.964, Spearman's r = 0.943; 95% CI: 0.922−0.964, Kendall's Tau r = 0.866; 95% CI: 0.836−0.896, Fleischers' r = 0.756; 95% CI: 0.624−0.888). The results of this study indicate a significant correlation between PFS2 and OS, which adds additional evidence to the existing literature of using PFS2 as a surrogate endpoint for OS in patients with PC.

The phase 3 studies, VOYAGE 1 and 2, were conducted to assess guselkumab in the treatment of patients with moderate-to-severe psoriasis. To investigate the efficacy and safety of guselkumab in Korean patients. The Korean sub-population of VOYAGE 1 and 2 study patients were included in this analysis. Efficacy and safety were evaluated through Weeks 24 and 28, respectively. Of 126 randomized Korean patients, 30, 63, and 33 received placebo, guselkumab, and adalimumab, respectively. At Week 16, guselkumab was superior to placebo in achieving an Investigator's Global Assessment (IGA) score of 0 or 1 (cleared or minimal; 90.5 vs. 20.0%, p<.001) and a Psoriasis Area and Severity Index (PASI) 90 response (71.4 vs. 3.3%, p<.001). At week 24, a significantly higher proportion of guselkumab-treated patients achieved PASI 75 and IGA 0 (clear skin) responses compared to adalimumab-treated patients (PASI 75: 93.7 vs. 66.7%, p<.001; IGA 0: 52.4 vs. 21.2%, p=.004). Through Week 28, guselkumab and adalimumab showed comparable safety profiles. The efficacy and safety of guselkumab in Korean psoriasis patients through 28 weeks were consistent with findings for the overall VOYAGE 1 and 2 study population. [ABSTRACT FROM AUTHOR]
