Age-related macular degeneration (AMD) is a leading cause of blindness, particularly in higher-income countries. Although dry AMD accounts for 85% to 90% of AMD cases, a comprehensive understanding of the global dry AMD burden is needed. A targeted literature review was conducted in PubMed, MEDLINE, Embase, and the Cochrane Database of Systematic Reviews (1995-2019) to identify data on the epidemiology, management, and humanistic and economic burden of dry AMD in adults. A landscape analysis of patient-reported outcome (PRO) instruments in AMD was also conducted via searches in PubMed (1995-2019), ClinicalTrials.gov, PROQOLID, PROLABELS, and health technology assessment reports (2008-2018). Thirty-seven of 4205 identified publications were included in the review. Dry AMD prevalence was 0.44% globally, varied across ethnic groups, and increased with age. Patients with dry AMD had higher risks of all-cause mortality (hazard ratio [HR] = 1.46; 95% CI, 0.99–2.16) and tobacco-related (HR = 2.86; 95% CI, 1.15–7.09) or cancer deaths (HR = 3.37; 95% CI, 1.56–7.29; P = 0.002) than those without dry AMD. Smoking, increasing age or cholesterol levels, and obesity are key risk factors for developing dry AMD. No treatment guidelines were identified for dry AMD specifically; management focuses on risk factor reduction and use of dietary supplements. In the United States and Italy, direct medical costs and health care resource utilization were lower in patients with dry versus wet AMD. Patients with dry AMD, particularly advanced disease, experienced significant visual function impairment. Dry AMD symptoms included reduced central vision, decreased ability to see at night, increased visual blurriness, distortion of straight lines and text, and faded color vision. Most PRO instruments used in AMD evaluations covered few, if any, of the identified symptoms reported by patients with dry AMD. Although the Quality of Life and Vision Function Questionnaire, 25-item National Eye Institute Vision Function Questionnaire, Low Vision Quality of Life, Impact of Vision Impairment–Very Low Vision, and Functional Reading Independence Index had strong content validity and psychometric properties in patients with dry AMD, they retained limited coverage of salient concepts. Despite dry AMD accounting for most AMD cases, there are substantial gaps in the published literature, particularly the humanistic and economic burden of disease and the lack of differentiation among dry, wet, or unspecified dry AMD. The significant burden of illness alludes to a high unmet need for tolerable and effective treatment options, as well as PRO instruments with more coverage of dry AMD symptoms and salient concepts.

Background Women with vasomotor symptoms (VMS) due to menopause frequently experience poor sleep quality. The Patient-Reported Outcomes Measurement Information System Sleep Disturbance – Short Form 8b (PROMIS SD-SF-8b) has been developed to assess sleep disturbance. The study objective was to use data from the fezolinetant SKYLIGHT 1 and 2 studies in individuals with VMS to assess the psychometric properties of the PROMIS SD-SF-8b. Methods Individuals (aged ≥ 40–≤65 years) with moderate-to-severe VMS (≥ 7 hot flashes/day) were enrolled. Besides PROMIS SD-SF-8b, eight other patient-reported outcome (PRO) measures were used for the psychometric evaluation. All the PRO assessments were completed at weeks 4 and 12 during the treatment period and most were completed at baseline. Psychometric analyses included factor analysis and reliability, construct validity, and sensitivity to change assessments. The within-patient threshold for a clinically meaningful change in sleep disturbance was derived. Results Overall, 1022 individuals were included from the SKYLIGHT 1 and 2 studies. Mean PROMIS SD-SF-8b total score at baseline was 26.80, which decreased to 22.68 at week 12, reflecting improved sleep disturbance. The confirmatory factor analysis supported the proposed PROMIS SD-SF-8b domain structure. Internal consistency was excellent, with Cronbach’s alpha values of 0.915 and 0.935 and a McDonald’s omega of 0.917. Item-to-item and item-total correlations were sufficient and moderate test-retest reliability was noted. The construct validity assessments showed that moderate Spearman rank correlations ( r : 0.608 to 0.651) were observed between PROMIS SD-SF-8b total scores and measures of sleep disturbance and sleep-related impairment, and that significant differences were noted in the total scores across PRO categories. The responsiveness of PROMIS SD-SF-8b total scores was supported by the results from the correlations in change scores and comparisons of mean change scores by PRO categories. Statistically significant differences in mean scores were observed between responder and non-responder PRO groups. A PROMIS SD-SF-8b total score of 8 points was identified as the within-patient threshold to use to confirm a meaningful change in sleep disturbance. Conclusions The psychometric properties of the PROMIS SD-SF-8b support its use to measure sleep disturbance in women with VMS due to menopause.

Background Peficitinib (ASP015K), a novel oral Janus kinase inhibitor, has demonstrated efficacy and safety in the treatment of patients with rheumatoid arthritis (RA). This study evaluated the effect of peficitinib on patient- and physician-reported outcomes in Asian patients with RA and an inadequate response to prior disease-modifying antirheumatic drugs (DMARDs). Methods Patients from two randomized, placebo-controlled, double-blind, phase 3 trials (RAJ3 and RAJ4) received once-daily peficitinib 100 mg, peficitinib 150 mg, or placebo, alone or in combination with DMARDs (RAJ3), or in combination with methotrexate (RAJ4). Mean changes in Work Productivity and Activity Impairment (WPAI) questionnaire domain scores from baseline, and percentages of patients achieving minimal clinically important differences (MCIDs) for patient- and physician-reported outcomes (WPAI, Health Assessment Questionnaire – Disability Index [HAQ-DI], and Subject’s Global Assessment of Pain [SGAP]), and Physician’s Global Assessment of disease activity (PGA) were evaluated at weeks 4, 8, 12, and 12/early termination (ET). Results Data from 1025 patients were analyzed. At week 12/ET in both studies, patients who received peficitinib 100 mg or 150 mg reported significantly improved WPAI domain scores from baseline (except for absenteeism in RAJ4) compared with placebo (both doses, p <0.05). A higher proportion of peficitinib- versus placebo-treated patients achieved MCID in WPAI, HAQ-DI, SGAP, and PGA in studies RAJ3 and RAJ4. Significant differences with peficitinib versus placebo were evident in both studies as early as week 4 in HAQ-DI (peficitinib 150 mg only), SGAP, and PGA, and week 8 in WPAI loss of work productivity and daily activity impairment. At week 12/ET, significantly higher proportions of patients receiving peficitinib versus placebo achieved MCID in HAQ-DI, SGAP, PGA, and WPAI domains of presenteeism (RAJ3 only), loss of work productivity (RAJ3 only), and daily activity impairment ( p <0.05 for all comparisons). Conclusions Peficitinib 100 mg or 150 mg administered daily over 12 weeks resulted in clinically meaningful improvements in outcomes that are important to RA patients, including pain, physical function, and work productivity and activity. These observations were reinforced through similar improvements in physicians’ rating of disease activity. Trial registration RAJ3: ClinicalTrials.gov, NCT02308163 , registered 4 December 2014. RAJ4: ClinicalTrials.gov, NCT02305849 , registered 3 December 2014.

IntroductionPeficitinib, a Janus kinase (JAK) inhibitor, is approved for clinical use in Japan, Korea, and Taiwan, but head-to-head comparisons versus other JAK inhibitors are lacking. We indirectly compared peficitinib, tofacitinib, and baricitinib for rheumatoid arthritis treatment.MethodsWe searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and congress archives up until February 12, 2019, for randomized controlled trials of peficitinib, tofacitinib, and baricitinib. Efficacy (American College of Rheumatology responses, disease activity scores, modified total Sharp score, Simplified Disease Activity Index [SDAI]) and safety outcomes were compared using a Bayesian network meta-analysis. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) consensus was followed for reporting results. A network meta-regression assessed the impact on outcomes of proportions of patients receiving concomitant methotrexate or of Asian ethnicity.ResultsThe network meta-analysis included 21 randomized controlled trials. At 12 weeks, all evaluable efficacy outcomes were comparable or improved with peficitinib 150 mg and 100 mg once daily, versus baricitinib 2 and 4 mg once daily and tofacitinib 5 mg twice daily. At 24 weeks, efficacy outcomes were comparable or improved for each peficitinib dose versus baricitinib and tofacitinib. Risk of adverse events and serious adverse events at 12 weeks were similar with peficitinib 100 and 150 mg versus baricitinib and tofacitinib. The proportion of patients receiving concomitant methotrexate had no effect on any outcome analyzed, but Asian ethnicity had a positive effect on multiple efficacy outcomes.ConclusionsPeficitinib had comparable efficacy versus tofacitinib and baricitinib for reduction in disease activity as measured by SDAI, and for reduction in progression of joint damage as measured radiographically. No notable differences in safety outcomes were observed. Further studies are required to better characterize the impact of ethnicity on the efficacy of JAK inhibitors.

ObjectiveEvaluation of the comparative effectiveness of enzalutamide and abiraterone in patients with metastatic castration-resistant prostate cancer (mCRPC) is limited to meta-analyses of randomized trials that exclude patients with significant comorbidities. We evaluated overall survival (OS) in patients with chemotherapy-naive mCRPC treated with enzalutamide or abiraterone acetate (abiraterone) in a real-world single payer setting.MethodsA retrospective analysis (4/1/2014–3/31/2018) of the Veterans Health Administration (VHA) database was conducted. Patients with mCRPC had ≥1 pharmacy claim for enzalutamide or abiraterone (first claim date = index date) following disease progression on surgical/medical castration, without chemotherapy <12 months prior to index date. Patients had continuous VHA enrollment for ≥12 months pre-index date and were followed until death, disenrollment, or end of study. Kaplan–Meier analysis and multivariable Cox proportional hazards regression models examined the OS treatment effect.ResultsPatients with chemotherapy-naive mCRPC (N = 3174; enzalutamide, n = 1229; abiraterone, n = 1945) had mean ages of 74 and 73 years, respectively. Median follow-up was 18.27 and 19.07 months with enzalutamide and abiraterone, respectively. Enzalutamide-treated patients had longer median treatment duration than abiraterone-treated patients (9.93 vs 8.47 months, respectively, p = 0.0008). After baseline comorbidity adjustment, enzalutamide-treated patients had a 16% reduced risk of death (hazard ratio [HR] = 0.84; 95% CI, 0.76–0.94; p = 0.0012). For patients who remained on first line-therapy only, enzalutamide-treated patients had improved OS versus abiraterone-treated patients (HR = 0.71; 95% CI, 0.62–0.82). Enzalutamide-treated patients who crossed over to abiraterone had a comparable risk of death versus abiraterone-treated patients who crossed over to enzalutamide (HR = 1.10; 95% CI, 0.89–1.35). These results were confirmed by sensitivity analysis, which considered prognostic variables.ConclusionsRetrospective analysis of the VHA database indicated that chemotherapy-naive patients with mCRPC initiating therapy with enzalutamide had improved survival versus abiraterone.

BackgroundBlack men are more likely to be diagnosed with aggressive prostate cancer (PC) and die from PC than white men. However, black men with metastatic castration-resistant PC (mCRPC) had longer overall survival (OS) than white men when treated with certain agents in clinical trials. We analyzed claims data from the Veterans Health Administration (VHA) database to evaluate OS in black and white men treated with enzalutamide or abiraterone (novel hormonal therapy [NHT]) for chemotherapy-naïve mCRPC.MethodsPatients with mCRPC aged ≥18 years were identified in the VHA database by diagnosis codes, evidence of surgical/medical castration, and a prescription claim for enzalutamide or abiraterone after castration from April 2014–March 2017. Cox models assessed associations between race and OS. Unadjusted and multivariable analyses were performed on the entire population and subsets based on the type of therapy received (if any) after NHT.ResultsIn total, 2910 patients were identified (787 black, mean 71.7 years; 2123 white, mean 74.0 years). Median follow-up was 19.0 and 18.7 months in blacks and whites, respectively. Black men had better survival versus white men: hazard ratios (95% CIs) were 0.89 (0.790–0.996; P = 0.044) and 0.67 (0.592–0.758; P < 0.0001) in the unadjusted and multivariable models, respectively. Statistically significantly longer OS was seen in black versus white men regardless of subsequent treatment, including no subsequent treatment.ConclusionsIn the VHA, black men with chemotherapy-naïve mCRPC initiating NHT may have better outcomes than similarly treated white men.

Background This analysis estimated the number needed to treat with enzalutamide versus bicalutamide to achieve one additional patient with chemotherapy-naïve metastatic castration-resistant prostate cancer who would obtain clinical benefit regarding progression-free survival, radiographic progression-free survival, or no prostate-specific antigen progression at 1 and 2 years following treatment initiation. Methods Clinical event rates were obtained from the STRIVE (NCT01664923) and TERRAIN (NCT01288911) trials, and the number needed to treat was the inverse of the absolute rate difference between the event rates of enzalutamide and bicalutamide. The 95% Confidence Interval of the number needed to treat was derived from the 95% Confidence Interval of the event rate difference. Results Using STRIVE data (patients with metastatic disease: n  = 128 enzalutamide; n  = 129 bicalutamide) comparing enzalutamide with bicalutamide at 1 and 2 years, the numbers needed to treat to achieve one additional patient with chemotherapy-naïve metastatic castration-resistant prostate cancer with progression-free survival were 2.0 and 2.8, respectively; with radiographic progression-free survival, 2.6 and 3.0, respectively; and without prostate-specific antigen progression, 1.8 and 2.4, respectively. Using TERRAIN data ( n  = 184 enzalutamide; n  = 191 bicalutamide) comparing enzalutamide with bicalutamide at 1 and 2 years, the numbers needed to treat to achieve one additional patient with progression-free survival were 4.3 and 3.7, respectively; with radiographic progression-free survival, 10.0 and 2.8, respectively; and without prostate-specific antigen progression, 2.1 and 3.2, respectively. Conclusions The combined data from TERRAIN and STRIVE demonstrated that treating chemotherapy-naïve metastatic castration-resistant prostate cancer with enzalutamide leads to more patients without clinical progression at 1 and 2 years than with bicalutamide.

Introduction Corticosteroids are a mainstay treatment for castration-resistant prostate cancer (CRPC). Although corticosteroids have been associated with adverse events, long-term outcomes related to their sustained use have not been assessed in men with CRPC. Objective This study evaluated the impact of cumulative corticosteroid exposure on the risk of developing specific adverse events in men with CRPC. Methods Data were obtained from administrative claims databases. Adult chemotherapy-naïve men who initiated CRPC treatment following surgical or medical castration were selected. Patients were grouped into four cohorts based on cumulative corticosteroid dose: no exposure, low exposure (< 0.5 g), medium exposure (0.5–2.0 g), and high exposure (> 2.0 g). Time to each adverse event was assessed using Kaplan–Meier analyses and time-dependent Cox proportional hazard models, adjusting for baseline characteristics. Results Overall, 9425 patients were included (no exposure, N  = 6765; low exposure, N  = 1660; medium exposure, N  = 655; high exposure, N  = 345). The mean age was 71–76 years across cohorts. During the study period, cumulative corticosteroid exposure was associated with a significantly higher risk of developing an infection [high vs. no exposure, adjusted hazard ratio (HR) 2.55; 95% confidence interval (CI) 2.27–2.85; p  < 0.001 for trend], peptic ulcer (HR 1.91; 95% CI 1.39–2.64; p  < 0.001), acute cardiovascular events (HR 1.62; 95% CI 1.43–1.83; p  < 0.001), endocrine disorder (HR 1.61; 95% CI 1.34–1.94; p  < 0.001), fracture (HR 1.59; 95% CI 1.37–1.86; p  < 0.001), or mental health condition (HR 1.28; 95% CI 1.06–1.55; p  = 0.014). Exposure to corticosteroids was associated with a more rapid onset of adverse events. Conclusion Patients with CRPC receiving corticosteroids had a higher risk of developing a wide range of adverse events than those not receiving them. The increased adverse event risk was observed after accounting, to the extent possible, for patients’ overall disease severity.
