Psychometric evaluation of the PROMIS SD-SF-8b instrument in individuals experiencing vasomotor symptoms due to menopause.

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.

Plain language summary: Does the amount of time it takes for prostate-specific antigen to double affect how long men with nonmetastatic castration-resistant prostate cancer live and their healthcare costs?

WHAT IS THIS SUMMARY ABOUT?: This is a plain language summary of a research article originally published in Clinical Genitourinary Cancer. The original article described the effect of rapidly rising prostate-specific antigen (PSA) levels on how long men with a type of advanced prostate cancer live and their healthcare costs. The prostate is a part of the male body that helps make semen. PSA is a protein produced by the prostate that can show how advanced prostate cancer has become. One measure of prostate cancer growth is assessing how quickly a patient's PSA level doubles. This is known as the PSA doubling time (PSADT). People with a shorter PSADT usually have faster-growing prostate cancer compared with people who have a longer PSADT of more than 12 months (long PSADT). Researchers wanted to know if PSADT can predict cancer spread (known as metastasis) or death for people with a type of advanced prostate cancer called non-metastatic castration-resistant prostate cancer (nmCRPC). Researchers also wanted to know if PSADT can predict healthcare costs. This could help doctors choose the right treatment for their patients with nmCRPC. This was a real-world study, not a clinical trial. This means that researchers looked at what happened when men received the treatments prescribed by their own doctor as part of their usual healthcare treatment. In this study, researchers used insurance claim information. WHAT WERE THE RESULTS?: Researchers looked at information for 2800 men with nmCRPC. Six out of every 10 men (60%) had a long PSADT of more than 12 months. Researchers found that it took longer for the cancer to spread to other parts of the body in men with a longer PSADT than men with PSADT of 12 months or less. Researchers also found that men with a longer PSADT lived longer than men with PSADT of 12 months or less. The long PSADT group had fewer healthcare visits overall than men with PSADT of 10 months or less. Over time, it cost less to treat men with a long PSADT than men with PSADT of 10 months or less. Generally, if PSADT was shorter, patients tended to do worse. WHAT DO THE RESULTS OF THE STUDY MEAN?: In this real-world study, researchers found that men with nmCRPC lived longer and had lower healthcare costs if they had a long PSADT of more than 12 months compared with men who had a shorter PSADT. Men with nmCRPC and a shorter PSADT may benefit from approved treatments that slow cancer spread and help them live longer. However, these treatments may have side effects and cost more than standard treatment. Doctors take all these things into account when choosing treatments for their patients. Most men in this study had a long PSADT of more than 12 months. Standard treatment may be the right choice for them because they are more likely to have better outcomes than men with a shorter PSADT.

Does race make a difference in how long men with advanced prostate cancer live when treated with abiraterone or enzalutamide?

WHAT IS THIS SUMMARY ABOUT?: This is a summary of a research article originally published in Prostate Cancer and Prostatic Diseases. There were few Black men in the clinical trials that led to the approval of the medications abiraterone and enzalutamide. Abiraterone and enzalutamide are the two most commonly used drugs to treat men with advanced prostate cancer that has progressed on traditional hormonal therapy. This type of prostate cancer is called metastatic castration-resistant prostate cancer (mCRPC). Overall, Black men have a higher likelihood of dying from prostate cancer than White men. Researchers wanted to find out if Black men and White men with mCRPC benefitted differently when treated with either abiraterone or enzalutamide. To do this, researchers looked at medical information from the Veterans Health Administration (VHA). The VHA is a large healthcare system for veterans in the US where everyone has equal access to treatment. This was a real-world study, not a clinical trial. This means that researchers looked at what happened when men received the treatments prescribed by their healthcare practitioners. WHAT WERE THE RESULTS?: After accounting for differences in the men's age and health conditions, researchers found that, on average, Black men with mCRPC actually lived 8 months longer than White men with mCRPC. WHAT DO THE RESULTS OF THE STUDY MEAN?: This real-world, US study of men with mCRPC treated with abiraterone or enzalutamide found that Black men lived longer than White men. All men in this study had equal access to healthcare and were treated with either abiraterone or enzalutamide. More research is needed to understand the reasons for this. Understanding these reasons could guide treatment to help men with mCRPC live longer.

Clinical and economic burden associated with stage III to IV triple-negative breast cancer: A SEER-Medicare historical cohort study in elderly women in the United States.

BACKGROUND: The current study was performed to describe patient characteristics, treatment patterns, survival, health care resource use (HRU), and costs among older women in the United States with advanced (American Joint Committee on Cancer stage III/IV) triple-negative breast cancer (TNBC) in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. METHODS: Women who were aged ≥66 years at the time of diagnosis and diagnosed with advanced TNBC between January 1, 2007, and January 1, 2011, in the SEER-Medicare database and who were followed for survival through December 31, 2013, were eligible. Patient demographic and clinical characteristics at the time of diagnosis, subsequent treatment patterns, and survival outcomes were analyzed. HRU and costs for the first 3 months after diagnosis, the last 3 months of life, and the time in between are summarized. All analyses were stratified by American Joint Committee on Cancer stage of disease. RESULTS: There were 1244 patients newly diagnosed with advanced TNBC; the majority were aged ≥75 years (61% with stage III disease and 57.4% with stage IV disease) and white (>70% of patients in both disease stage groups). The most common treatment approaches were surgery combined with chemotherapy for patients for stage III disease (50.6%) and chemotherapy alone or with radiotherapy for patients with stage IV disease (31.3%). Diverse chemotherapy regimens were administered for each line of therapy; nevertheless, the medications used were consistent with national guidelines. Patients with stage III and stage IV disease were found to have a similar mean number of hospitalizations and outpatient visits, but mean monthly costs were greater for patients with stage IV disease at all 3 time points. The mean cost per patient-month (in 2013 US dollars) was $4810 for patients with stage III disease and $9159 for patients with stage IV disease. CONCLUSIONS: Among older women with advanced TNBC, significant treatment variations and considerable HRU and costs exist. Further research is needed to find effective treatments with which to reduce the clinical and economic burden of this disease. Cancer 2018;124:2104-14. © 2018 American Cancer Society.

Number-needed-to-treat analysis of clinical progression in patients with metastatic castration-resistant prostate cancer in the STRIVE and TERRAIN trials.

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. TRIAL REGISTRATION: STRIVE (NCT01664923; registration date: August 10, 2012) and TERRAIN (NCT01288911; registration date: February 1, 2011).

Psychometric Evaluation of the MENQOL Instrument in Women Experiencing Vasomotor Symptoms Associated with Menopause.

INTRODUCTION: Vasomotor symptoms (VMS) associated with menopause can negatively affect health-related quality of life (HRQoL). The Menopause-Specific Quality of Life (MENQOL) questionnaire has been developed to assess QOL specific to menopause. The objective of the current study was to assess the psychometric properties, sensitivity to change, and clinically meaningful within-patient change of the MENQOL using data from the fezolinetant SKYLIGHT 1 and 2 studies in individuals with VMS. METHODS: Individuals aged ≥ 40 to ≤ 65 years with moderate-to-severe VMS (≥ seven hot flashes/day) were enrolled. In addition to MENQOL, eight patient-reported outcome (PRO) measures were used for the psychometric evaluation. All 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 MENQOL was derived. RESULTS: In total, 1022 individuals were included from SKYLIGHT 1 and 2. Mean MENQOL total score at baseline was 4.30, improving to 3.16 at week 12. The confirmatory factor analysis supported established MENQOL domain structure, including the overall score. The internal consistency of the MENQOL overall and domain scores was supported using Cronbach's alpha and McDonald's omega, and MENQOL construct validity was supported for overall and domain scores. Item-to-item and item-total correlations were generally sufficient, and moderate test-retest reliability was noted. The scales against which construct validity and responsiveness for MENQOL domains were examined were moderately related to the MENQOL domains in general, providing additional support for acceptable measurement properties of MENQOL in this population. A reduction in MENQOL overall score of ≥ 0.9 points was identified as responding to treatment (a clinically important threshold). Thresholds of 2.0 points for the vasomotor domain and 0.9 for the psychosocial domain were estimated, in addition to distribution-based threshold estimates of 0.8 and 1.2 for the physical and sexual domains, respectively. CONCLUSIONS: The psychometric properties of the MENQOL overall and domain scores support use of this instrument to capture experiences among individuals with moderate-to-severe VMS associated with menopause and assess related endpoints in clinical trials.

Dry Age-Related Macular Degeneration: Distribution of Visual Acuity and Progression Risk in a Large Registry.

INTRODUCTION: Understanding the progression to geographic atrophy (GA) in late dry age-related macular degeneration (dAMD) can support development opportunities for dAMD treatments. We characterized dAMD by distribution of visual acuity (VA) categories and evaluated VA progression risk by disease stage. METHODS: This retrospective observational study used data from the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) to identify patients diagnosed with dAMD in ≥ 1 eye from January 2016 through December 2019 (index date) with ≥ 1 visit and ≥ 1 VA measurement recorded post-index date. Patients were followed until the date of last visit, last contribution for diagnosing provider, or diagnosis of neovascular AMD post-index. Models were utilized to describe the distribution of VA categories and progression to worsening VA. RESULTS: Data from 593,277 patients were analyzed. At baseline, 64.4% had mild disease, 29.4% intermediate, and 2.9%/3.3% had GA with/without subfoveal involvement. Most patients with mild (88.4%) and intermediate (79.7%) disease and GA without subfoveal involvement (57.1%) had baseline VA ≥ 20/63 in the study eye; 72.0% of patients with GA with subfoveal involvement had VA < 20/63. Modeled results showed lower VA with more progressive stage at baseline. Annual probability of stable dAMD based on baseline stage ranged from 82.1% (GA without) to 92.3% (GA with subfoveal involvement). Annual progression probability to GA without/with subfoveal involvement was 0.4% for mild and 5.5% for intermediate disease and from dry to neovascular AMD, 0.5% for mild and 8.0% for intermediate disease. CONCLUSIONS: Results from this analysis of a large database of electronic health records complement those from randomized trials and show that patients with more advanced dAMD have lower VA at baseline and that VA progression is generally faster with each progressive stage. Together these findings highlight the disease burden and trajectory of dAMD as well as opportunities for addressing unmet needs.

Dry age-related macular degeneration (dAMD) is a disease that progressively worsens over time. As the disease progresses, patients start to lose their vision, leading to a substantial burden on their quality of life and finances due to the need for increased healthcare services. As of 2022, there are no medications available to reverse or stop worsening of dAMD. This study used real-world data from a large registry of electronic health records to increase the understanding of how patients progress through the stages of dAMD. By reviewing patient records, we were able to identify approximately 600,000 patients with confirmed dAMD. These patients were then followed over time, and we were able to confirm that patients with a lower ability to see at the beginning of our review period had more advanced dAMD. We also found that as patients' disease worsened, their vision also decreased. These findings highlight the need for new medication options to reverse or delay the worsening of dAMD and improve the quality of life for patients.

Prevalence and quality-of-life burden of vasomotor symptoms associated with menopause: A European cross-sectional survey.

OBJECTIVES: To determine, in a European cohort, the prevalence and health-related quality-of-life (QOL) burden of moderate-to-severe vasomotor symptoms (VMS) in postmenopausal women, and among subgroups of women not taking hormone therapy (HT). STUDY DESIGN: Screening surveys were sent to a random sample of women aged 40-65 years; those meeting the inclusion criteria completed the full questionnaire. Women with successfully treated VMS or breast cancer or who were receiving HT for medical conditions were excluded. MAIN OUTCOME MEASURES: Frequency and duration of VMS, perceptions of menopause, seeking advice from a healthcare professional, treatment for VMS symptoms, perceptions of HT use, out-of-pocket costs, and other approaches to coping with menopause. The Menopause-Specific QOL (MENQOL) questionnaire and Work Productivity and Activity Impairment (WPAI) questionnaire were included. RESULTS: Of 11,452 women who completed the screening survey, 5178 were postmenopausal and 2035 completed the full questionnaire. Prevalence of moderate-to-severe VMS ranged from 31 % in France to 52 % in Italy. The majority were in the HT-caution or HT-averse group, despite being eligible for HT. Most common menopausal symptoms reported in the MENQOL were "feeling tired or worn out," with aching in muscles and joints reported as the most common symptom in Spain. Weight gain was the most bothersome symptom in all countries, except for Spain, where low backache was more bothersome. Hot flashes and night sweats had a greater impact on daily than on working activities, as measured by the WPAI. CONCLUSIONS: A high proportion of European women reported experiencing moderate-to-severe VMS, with associated symptoms influencing QOL.

Survival and Economic Impact of Rapid Prostate-Specific Antigen Doubling Time in Patients With Nonmetastatic Castration-Resistant Prostate Cancer.

INTRODUCTION: In patients with nonmetastatic castration-resistant prostate cancer (nmCRPC), prostate-specific antigen doubling time (PSADT) is associated with risk of metastasis and survival. This study evaluated the association of PSADT with clinical and economic outcomes in a real-world setting among patients with nmCRPC not receiving novel hormonal therapy (NHT), using 2-month PSADT thresholds. PATIENTS AND METHODS: We retrospectively identified Veterans Health Administration patients with nonmetastatic prostate cancer and ≥2 PSA increases after medical/surgical castration (2012-2016). The third measurement was the index (CRPC) date. Patients with ≥3 postindex PSA measurements, including index, were followed until death or ≥12 months until disenrollment, study end, or death, and grouped into 2-month cohorts based on postindex PSADT. Cox regression models assessed association between PSADT, time to metastasis, and death. Healthcare resource utilization and costs were evaluated. RESULTS: Among 2800 evaluable patients, median follow-up was 30 months and median PSADT was 17 months. Relative to the reference cohort (PSADT >12 months), all cohorts had significantly higher metastasis risk. PSADT ≤10-month cohorts had significantly greater mortality risk than the reference; hazard ratios (95% confidence intervals) ranged from 12.3 (9.2, 16.4) in the PSADT ≤2-month cohort to 1.3 (0.9, 2.0) in the >10 to ≤12-month cohort. Total costs were significantly higher for cohorts up to and including the PSADT >8 to ≤10-month cohort, than for the reference cohort. Mean per patient per month all-cause medical plus pharmacy costs were $6623, $4768, and $4049 in the PSADT ≤2-month, >2 to ≤4-month cohort, and >4 to ≤6-month cohorts, respectively, versus $1911 in the PSADT >12-month cohort (P <0.05). CONCLUSION: Most patients with nmCRPC have PSADT >12 months and a long natural history. For those with shorter PSADT, the risk of metastasis, death, and costs increased. These data can help select patients for NHT and conversely those who can safely delay NHT for nmCRPC.

Epidemiology and treatment patterns of UK women diagnosed with vasomotor symptoms: Findings from the Clinical Practice Research Datalink GOLD database.

OBJECTIVES: To describe the epidemiology and treatment of vasomotor symptoms (VMS) in the UK. STUDY DESIGN: Retrospective study that used electronic medical records from UK primary care centers. MAIN OUTCOME MEASURES: The prevalence and incidence of moderate-to-severe VMS, the proportion treated, persistence with initial treatment, treatment patterns, and menopausal hormone therapy (HT) experience were investigated over the study period (Jan. 2009-Dec. 2018). The study population comprised women aged 40-65 years registered at general practitioner clinics. For incident cases, the uptake of pharmacological non-hormonal or hormonal treatment was recorded, which included experience of HT. RESULTS: Over the 10-year study period, 1,481,646 women were included from the database, among whom there were 313,031 prevalent and 90,434 incident cases of VMS. Annual prevalence and incidence rates were stable over time, with a weighted average of 21.1 % and 15.3 per 1000 person-years, respectively (results varied across age groups). Among women who were incident VMS cases, 32.4 % (29,275) were initially prescribed non-hormonal treatments for a median of 3.9 months, 49.4 % (44,700) were prescribed hormonal treatments for 4.0 months, and 18.2 % (16,459) had no treatment. Approximately one-third of treated women switched between non-hormonal and hormonal treatments. The HT experience results showed that 52.7 % (47,639) of women were HT-eligible, 13.1 % (11,872) were HT-contraindicated (they may or may not have received HT), and 34.2 % (30,923) did not receive HT. CONCLUSIONS: Variations in prescribed treatment patterns suggest that education may be needed for clinicians and women regarding the potential pharmacological options for treating VMS in the UK.

Evaluation of the impact, treatment patterns, and patient and physician perceptions of vasomotor symptoms associated with menopause in Europe and the United States.

OBJECTIVES: This study elicited the views of physicians and patients with vasomotor symptoms (VMS) associated with menopause on the impact of VMS and treatment patterns/perceptions. STUDY DESIGN: Data from the Adelphi VMS Disease Specific Programme, a point-in-time survey conducted in 5 European countries and the United States in 2020, were used. Primary care providers (PCPs) and gynecologists seeing ≥3 patients/week with VMS associated with menopause completed a survey and chart review; their patients were invited to complete a survey and questionnaires. MAIN OUTCOME MEASURES: Physicians reported treatment patterns and patient-specific symptoms and treatment preferences. Patients described symptoms, impact of VMS, and treatment satisfaction. RESULTS: Participants included 115 PCPs and 118 gynecologists. Physicians reviewed the charts of 1816 patients, 854 of whom completed surveys. Moderate/severe impact of VMS on sleep, mood, quality of life, and work/study was reported by 35.8 %, 31.6 %, 23.6 %, and 15.4 % of women, respectively. Based on chart review, 64.8 % of women were currently prescribed treatment for VMS, most commonly hormone therapy (HT; 73.1 %), followed by selective serotonin or serotonin-norepinephrine reuptake inhibitors (31.3 %). Most women (57.3 %) with VMS were eligible for HT but averse to using it. Despite 91.4 % of physicians finding HT to be effective, 62.7 % agreed (slightly-strongly) that their patients are generally reluctant to use it. One-third of women were dissatisfied with VMS control. CONCLUSIONS: VMS can considerably impact daily life. Effective treatment options that are better accepted could potentially improve management of VMS and lead to better quality of life for women with VMS associated with menopause. CLINICAL TRIAL REGISTRATION: None.

Survival by race in men with chemotherapy-naive enzalutamide- or abiraterone-treated metastatic castration-resistant prostate cancer.

BACKGROUND: Black 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. METHODS: Patients 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. RESULTS: In 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. CONCLUSIONS: In the VHA, black men with chemotherapy-naïve mCRPC initiating NHT may have better outcomes than similarly treated white men.

Global Burden of Dry Age-Related Macular Degeneration: A Targeted Literature Review.

PURPOSE: 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. METHODS: 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). FINDINGS: 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. IMPLICATIONS: 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.

The Patient Experience: Symptoms and Impact of Dry Age-Related Macular Degeneration.

INTRODUCTION: No published literature systematically explores the dry age-related macular degeneration (AMD) patient experience. To inform the development of patient-reported outcome measures (PROMs), the important and relevant signs, symptoms, and impacts for patients with dry AMD were identified. METHODS: A holistic approach was used to capture, define, and organize the signs, symptoms, and impacts that are important to patients with dry AMD. Qualitative evidence was identified through a targeted literature review and clinician (N = 5) and patient (N = 20) interviews. The targeted review was expanded to include patients with AMD, as few studies specific to dry AMD were identified. The qualitative evidence was incorporated into a conceptual model that included the signs, symptoms, and impacts of dry AMD affecting the patient experience. RESULTS: Twenty-nine articles (dry AMD, N = 5; general AMD, N = 24) exploring health-related quality-of-life evidence in patients with AMD were identified. Concepts identified and included in the preliminary, literature-based model included signs and symptoms related to general vision loss and general impacts (e.g., dependency on others, poor spatial perception/mobility, difficulty reading, emotional affects). No concepts unique to dry AMD were identified. Interviewed clinicians refined the literature-based model. Across all visual acuity severities, ≥ 80% of patients reported difficulty driving, reading, and completing activities of daily living, along with frustration and dependency on others; all patients reported blurred vision. The final model included 35 signs, symptoms, and impacts, with 19 considered salient. CONCLUSIONS: To better understand the patient experience, we captured, defined, and organized signs, symptoms, and impacts into a dry AMD conceptual model. This model can aid in the development of PROMs reflecting the experience of patients with dry AMD.

Global cross-sectional survey of women with vasomotor symptoms associated with menopause: prevalence and quality of life burden.

OBJECTIVE: To determine prevalence and health-related quality of life (HRQOL) of moderate-to-severe vasomotor symptoms (VMS) in postmenopausal women in Europe, the US, and Japan, and among subgroups of women not taking hormone therapy (HT). METHODS: Screening surveys were sent to a random sample of women aged 40 to 65 years; full questionnaires followed to those who completed them and met inclusion criteria. Women with successfully treated VMS, breast cancer, or on HT for medical conditions were excluded. The Menopause-Specific QOL (MENQOL) and Work Productivity and Activity Impairment (WPAI) questionnaires were included in the questionnaire. RESULTS: Of 25,161 women completing the screening survey, 11,771 were postmenopausal and 3,460 met inclusion criteria and completed the full questionnaire. Prevalence of moderate-to-severe VMS was 40%, 34%, and 16% in Europe, the US, and Japan, respectively. A large proportion were HT averse, albeit eligible (Europe 56%, US 54%, Japan 79%). In total, 12%, 9%, and 8% in Europe, the US, and Japan, respectively, were HT-contraindicated. A high proportion were HT-cautious (Europe 70%, US 69%, Japan 52%). Most common menopausal symptoms reported in the MENQOL were feeling tired or worn out (Europe/US 74%, Japan 75%), aching in muscles and joints (Europe 69%, US 68%, Japan 61%), difficulty sleeping (Europe 69%, US 66%, Japan 60%), and hot flashes (Europe 67%, US 68%, Japan 62%). Overall, the most bothersome symptom was weight gain. As measured by the WPAI, hot flashes and night sweats had a greater impact on daily activities than on working activities. CONCLUSIONS: A high proportion of women experienced moderate-to-severe VMS, with associated symptoms impacting QOL.

Survival outcomes in patients with chemotherapy-naive metastatic castration-resistant prostate cancer treated with enzalutamide or abiraterone acetate.

OBJECTIVE: Evaluation 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. METHODS: A 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. RESULTS: Patients 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. CONCLUSIONS: Retrospective analysis of the VHA database indicated that chemotherapy-naive patients with mCRPC initiating therapy with enzalutamide had improved survival versus abiraterone.

Patient- and physician-reported outcomes from two phase 3 randomized studies (RAJ3 and RAJ4) of peficitinib (ASP015K) in Asian patients with rheumatoid arthritis.

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.

Comparative Efficacy and Safety of Peficitinib Versus Tofacitinib and Baricitinib for Treatment of Rheumatoid Arthritis: A Systematic Review and Network Meta-Analysis.

INTRODUCTION: Peficitinib, 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. METHODS: We 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. RESULTS: The 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. CONCLUSIONS: Peficitinib 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.

Budget Impact of Enzalutamide for Nonmetastatic Castration-Resistant Prostate Cancer.

BACKGROUND: Prostate cancer is the most common cancer and second-leading cause of cancer death among men in the United States. Prostate cancer poses a large economic burden, which increases with progression from localized to metastatic disease. Newly approved treatments for non-metastatic castration-resistant prostate cancer (nmCRPC) delay disease progression and reduce the risk of metastatic disease. Quantifying the potential budget impact of these new treatments is of interest to health care decision makers. OBJECTIVE: To estimate the budget impact of enzalutamide for the treatment of patients with nmCRPC in the United States over a 3-year time horizon. METHODS: An Excel-based model was developed to estimate the budget impact to a U.S. health plan of enzalutamide, a second-generation antiandrogen, as an add-on to androgen deprivation therapy (ADT) for the treatment of high-risk nmCRPC patients (prostate-specific antigen doubling time of ≤ 10 months). Comparators include apalutamide + ADT, bicalutamide + ADT, and ADT only. The analysis includes treatment costs for nmCRPC and for treatment after progression to metastatic castration-resistant prostate cancer (mCRPC). The treated population size was estimated from epidemiological data and literature. Dosing, duration of therapy, and adverse event rates were based on package inserts and pivotal studies. RED BOOK, Centers for Medicare & Medicaid Services fee schedules, and literature were used to obtain costs of drugs, adverse events, and health care visits. Market shares were estimated for each comparator before and after enzalutamide adoption. A 1-way sensitivity analysis was performed to quantify the impact of parameter uncertainty. RESULTS: In a hypothetical 1-million-member plan with 3% annual growth, it was estimated that there would be approximately 19 eligible incident nmCRPC patients in year 1, increasing to 20 eligible incident patients in year 3. With an assumed market share of approximately 6% for enzalutamide in year 1, the budget impact would be $106,074 ($0.009 per member per month [PMPM]). With a 26% enzalutamide share in year 3, the budget impact would be $632,729 ($0.048 PMPM). Cumulative budget impact to the health plan over 3 years is estimated to be $1,082,095 ($0.028 PMPM). The increased cost of the treatment regimen is partly offset by reduced postprogression costs. CONCLUSIONS: Treatment of nmCRPC patients with enzalutamide has a modest budget impact that is partly offset by delaying progression to mCRPC.
