Early Real-World Patient and Staff Experience with an Intracanalicular Dexamethasone Insert.

Purpose: To evaluate both the early experience of real-world patients treated with dexamethasone ophthalmic insert (0.4 mg; DEXTENZA®), hereafter referred to as DEX, after cataract surgery as well as staff/practice integration of DEX relative to eyedrops. Patients and Methods: This was a cross-sectional survey study of 23 cataract practices in the United States. Respondents were patients and practice staff who had experience with DEX following cataract surgery. Both patients and practice staff completed an online survey. Descriptive statistics summarized the survey responses to portray the experience of the respondents. Results: Surveys were completed by 62 patients and 19 practice staff. Almost all patients (93%) were satisfied or extremely satisfied with DEX. Patients highly preferred DEX (93%) to topical steroid drops (7%) based on past experiences with topical steroid drops. Most practice staff (95%) were satisfied or highly satisfied with DEX, reporting a 45% reduction in time spent educating patients on postoperative drop use and a 46% decrease in time spent addressing calls from pharmacies regarding postoperative medications. Conclusion: Incorporating the DEX insert into clinical practice in cataract surgery practices can improve patient adherence, while potentially providing significant savings to practices in terms of time spent educating patients and responding to patient and pharmacy call-backs.

Cost-Effectiveness of eRAPID eHealth Intervention for Symptom Management During Chemotherapy.

PURPOSE: A randomized controlled trial of online symptom monitoring during chemotherapy with electronic patient self-Reporting of Adverse-events: Patient Information and aDvice (eRAPID) system found improved symptom control and patient self-efficacy, without increasing hospital admissions and visits. The aim of this study was to evaluate the cost-effectiveness of the eRAPID eHealth intervention compared with usual care for patients receiving systemic treatment for colorectal, breast, or gynecologic cancers in the United Kingdom. METHODS: An embedded economic evaluation was conducted alongside the trial evaluating the effectiveness of eRAPID from health care provider and societal perspectives. Costs and quality-adjusted life-years (QALYs) of patients were compared over 18 weeks of the trial. Incremental cost-effectiveness ratios (ICERs) were estimated and compared with the National Institute for Health and Care Excellence cost-effectiveness threshold. Uncertainty around the ICER was explored using nonparametric bootstrapping and sensitivity analyses. Follow-up data were collected 12-months after random assignment for a subset of the study sample to conduct exploratory analysis of potential longer-term effects. RESULTS: Patients in the eRAPID group had the highest QALY gain and lowest costs over 18 weeks. Although differences were small and not statistically significant, eRAPID had a 55%-58% probability of being more cost-effective than usual care. Patient out-of-pocket costs were lower in the eRAPID group, indicating eRAPID may help patients access support needed within the National Health Service. Exploratory 12-months analysis showed small differences in costs and QALYs, with higher QALY gains in the eRAPID group but also higher costs. Exploratory subgroup analysis by disease status indicated that the eRAPID intervention was cost-effective for patients with early-stage cancers but not for patients with metastatic disease. CONCLUSION: Despite small differences in QALYs and costs, the analyses show potential cost-effectiveness of online symptom monitoring, when added to usual care, particularly during adjuvant systemic treatment for early-stage cancers.

Anti-vascular endothelial growth factor dosing frequency and visual outcomes in macular oedema following branch retinal vein occlusion.

OBJECTIVES: To determine the relationship between treatment frequency with intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents and visual acuity (VA) outcomes in eyes with macular oedema (MO) secondary to branch retinal vein occlusion (BRVO) in US clinical practice. METHODS: Study eyes that initiated anti-VEGF injections between January 2012 and May 2016 were followed for ≥1 year in a retrospective analysis of medical records (Vestrum Health database). Eyes were analysed in 2 cohorts by treatment duration (years 1 and 2) and then in 2 subcohorts by injection frequency (≤6 or ≥7 injections/year). RESULTS: Among 3099 eyes with MO secondary to BRVO, 1197 (38.6%) received ≤6 injections (mean injections, 4.6; baseline mean VA, 53 letters) and 1902 (61.4%) received ≥7 injections through 1 year (mean injections, 8.8; baseline mean VA, 52 letters). At year 1, mean VA gain from baseline was 10.4 versus 13.9 letters in eyes receiving ≤6 versus ≥7 injections (p < 0.001). At year 2, mean VA in eyes receiving ≤6 (n = 42) versus ≥7 injections (n = 227) was 64 versus 68 letters, respectively (p = 0.19). Mean VA change between the start and end of year 2 in eyes receiving ≥7 injections in year 1 and ≤6 in year 2 differed significantly from that of eyes receiving ≥7 injections in both years (-3.0 vs 0.7 letters, respectively; p < 0.001). CONCLUSIONS: In routine clinical practice, more frequent dosing with anti-VEGF agents was associated with greater visual benefits in eyes with MO secondary to BRVO.

Online Symptom Monitoring During Pelvic Radiation Therapy: Randomized Pilot Trial of the eRAPID Intervention.

PURPOSE: Radiation therapy (RT) and chemoRT for pelvic cancers increase survival but are associated with serious treatment-related symptoms. Electronic-patient self-Reporting of Adverse-events: Patient Information and aDvice (eRAPID) is a secure online system for patients to self-report symptoms, generating immediate advice for hospital contact or self-management. This pilot study aimed to establish feasibility and acceptability of the system. METHODS AND MATERIALS: In a prospective 2-center randomized parallel-group pilot study, patients undergoing radical pelvic RT for prostate cancer (prostateRT) or chemoRT for lower gastrointestinal and gynecological cancers were randomized to usual care (UC) or eRAPID (weekly online symptom reporting for 12, 18, and 24 weeks). Primary outcomes were recruitment/attrition, study completion, and patient adherence. Secondary outcomes were effect on hospital services and performance of patient outcome measures. Missing data, floor/ceiling effects, and mean change scores were examined for Functional Assessment of Cancer Therapy (FACT-G), European Organisation for Research and Treatment of Cancer, Quality of Life (EORTC QLQ C-30), self-efficacy, and EuroQol (EQ5D). RESULTS: From 228 patients approached, 167 (73.2%) were consented and randomized (83, eRAPID; 84, UC; 87, prostateRT; 80, chemoRT); 150 of 167 completed 24 study weeks. Only 16 patients (9.6%) withdrew (10, eRAPID; 6, UC). In the eRAPID arm, completion rates were higher in patients treated with prostateRT compared with chemoRT (week 1, 93% vs 69%; week 2, 93% vs 68%; week 12, 69% vs 55%). Overall, over 50% of online reports triggered self-management advice for milder adverse events. Unscheduled hospital contact was low, with no difference between eRAPID and UC. Return rates for outcome measures were excellent in prostateRT (97%-91%; 6-24 weeks) but lower in chemoRT (95%-55%; 6-24 weeks). Missing data were low (1%-4.1%), ceiling effects were evident in EQ5D-5L, self-efficacy-scale, and FACT-Physical Wellbeing. At 6 weeks, the chemoRT-eRAPID group showed less deterioration in FACT-G, EORTC QLQ-C30, and EQ5D-Visual Analogue Scale than UC, after baseline adjustment. CONCLUSIONS: eRAPID was successfully added to UC at 2 cancer centers in different patient populations. Acceptability and feasibility were confirmed with excellent adherence by prostate patients, but lower by those undergoing chemoRT for gynecological cancers.

Early Real-World Physician Experience with an Intracanalicular Dexamethasone Insert.

Purpose: To describe the early real-world experience of physicians with an intracanalicular dexamethasone insert (DEX) in patients undergoing cataract surgery and to capture the clinical impact of adopting this therapy. Patients and Methods: 23 United States sites including Ambulatory Surgical Center Setting (ASC) and Outpatient Clinical settings. Respondents were physicians who had early experience with DEX in cataract surgery patients. This was a Phase 4 experiential cross-sectional survey study comprised of 3 sequential online physician surveys. Descriptive statistics summarized the surveys' responses to determine the early impressions of the respondents. Results: Forty-two physicians completed surveys. On average, physicians reported feeling comfortable administering DEX after placing 3 inserts (mean 2.7; standard deviation 1.9). Most physicians (92%) were satisfied with DEX, and all physicians (100%) reported that DEX improved patient compliance. Most physicians (62.5%) indicated they would highly prefer DEX over traditional steroid eyedrops for the management of post-surgical inflammation and pain. Conclusion: The surveys exploring the early use of DEX suggest that DEX is a clinically effective treatment with a rapid initial learning curve and integrates well into clinical use. Physicians had a very positive early experience with DEX, including comfort with insertion and satisfaction. DEX shows promise as a primary treatment choice of physicians for ocular inflammation and pain following cataract surgery by offering patients a hands-free innovative therapy that delivers a preservative-free steroid to the ocular surface over approximately 30 days.

Phase III Randomized Controlled Trial of eRAPID: eHealth Intervention During Chemotherapy.

PURPOSE: Electronic patient self-Reporting of Adverse-events: Patient Information and aDvice (eRAPID) is an online eHealth system for patients to self-report symptoms during cancer treatment. It provides automated severity-dependent patient advice guiding self-management or medical contact and displays the reports in electronic patient records. This trial evaluated the impact of eRAPID on symptom control, healthcare use, patient self-efficacy, and quality of life (QOL) in a patient population treated predominantly with curative intent. METHODS: Patients with colorectal, breast, or gynecological cancers commencing chemotherapy were randomly assigned to usual care (UC) or the addition of eRAPID (weekly online symptom reporting for 18 weeks). Primary outcome was symptom control (Functional Assessment of Cancer Therapy-General, Physical Well-Being subscale [FACT-PWB]) assessed at 6, 12, and 18 weeks. Secondary outcomes were processes of care (admissions or chemotherapy delivery), patient self-efficacy, and global quality of life (Functional Assessment of Cancer Therapy-General, EQ5D-VAS, and EORTC QLQ-C30 summary score). Multivariable mixed-effects repeated-measures models were used for analyses. Trial registration: ISRCTN88520246. RESULTS: Participants were 508 consenting patients (73.6% of 690 eligible) and 55 health professionals. eRAPID compared to UC showed improved physical well-being at 6 (P = .028) and 12 (P = .039) weeks and no difference at 18 weeks (primary end point) (P = .69). Fewer eRAPID patients (47%) had clinically meaningful physical well-being deterioration than UC (56%) at 12 weeks. Subgroup analysis found benefit in the nonmetastatic group at 6 weeks (P = .0426), but not in metastatic disease. There were no differences for admissions or chemotherapy delivery. At 18 weeks, patients using eRAPID reported better self-efficacy (P = .007) and better health on EQ5D-VAS (P = .009). Average patient compliance with weekly symptom reporting was 64.7%. Patient adherence was associated with clinician's data use and improved FACT-PWB at 12 weeks. CONCLUSION: Real-time monitoring with electronic patient-reported outcomes improved physical well-being (6 and 12 weeks) and self-efficacy (18 weeks) in a patient population predominantly treated with curative intent, without increasing hospital workload.

Dropless cataract surgery: modernizing perioperative medical therapy to improve outcomes and patient satisfaction.

PURPOSE OF REVIEW: Advances in pharmacology offer freedom from topical medical therapy without compromise of anti-inflammatory and antimicrobial coverage in the perioperative period. In this review, we describe the basis for dropless cataract surgery with the goal of improving outcomes and the patient experience. RECENT FINDINGS: Phacoemulsification outcomes depend largely on surgeon skill but also on adherence to a complex multidrug regimen of perioperative anti-inflammatory and antimicrobial therapy to prevent sight-threatening complications such as cystoid macular edema or endophthalmitis. Successful administration of this regimen can be limited by noncompliance, difficulty administering eye drops, bioavailability, and side effects, among others. The recent development of sustained-release formulations of dexamethasone - one an intracanalicular insert and the other an intraocular suspension - can provide sustained tapering doses of dexamethasone while reducing or eliminating the need for anti-inflammatory eye drop therapy. Similarly, mounting evidence compellingly demonstrates that intracameral antibiotic use intraoperatively is at least as effective as topical antibiotics in preventing endophthalmitis. SUMMARY: Sustained-release dexamethasone coupled with intracameral antibiotics at the time of phacoemulsification can provide antimicrobial and anti-inflammatory prophylaxis without the need for topical eye drop medications. This approach has the potential to improve compliance with therapy, visual acuity outcomes, and the overall patient experience.

Outcomes by Baseline Choroidal Neovascularization Features in Age-Related Macular Degeneration: A Post Hoc Analysis of the VIEW Studies.

PURPOSE: To assess the influence of baseline choroidal neovascularization (CNV) features on visual change and fluid resolution after anti-vascular endothelial growth factor (VEGF) treatment of eyes with neovascular age-related macular degeneration (nAMD). DESIGN: Post hoc analysis of 52-week data from the phase 3 Vascular Endothelial Growth Factor VEGF Trap-Eye: Investigation of Efficacy and Safety in Wet Age-Related Macular Degeneration (AMD) Studies (VIEW) 1 and 2 clinical trials. PARTICIPANTS: One thousand eight hundred four patients with nAMD. METHODS: Integrated data from VIEW 1 and 2 of 1804 eyes receiving intravitreal aflibercept injections (IAIs) 2 mg every 4 weeks, IAIs 2 mg every 8 weeks after 3 initial monthly doses, and ranibizumab every 4 weeks with documented baseline CNV type, total area, and leakage area were analyzed. Time to an event and cumulative incidence were evaluated by Kaplan-Meier analysis, and relative risks were estimated using proportional hazards analysis. MAIN OUTCOMES MEASURES: Cumulative incidence of time to first sustained vision gain of 15 or more Early Treatment Diabetic Retinopathy Study letters, vision loss of more than 5 Early Treatment Diabetic Retinopathy Study letters from baseline, as well as first sustained absence of retinal fluid and intraretinal fluid as evaluated by OCT with respect to CNV type, total CNV, and leakage area. RESULTS: Eyes with predominantly classic CNV (mean best-corrected visual acuity [BCVA], 48.2 letters at baseline) showed a higher incidence rate of first sustained gain of 15 letters or more than eyes with occult CNV (mean BCVA, 57.9 letters at baseline; P < 0.01). Eyes with occult CNV at baseline showed higher incidence rates of first sustained absence of retinal fluid and of intraretinal fluid than eyes with predominantly classic CNV (both P < 0.01). With increasing baseline CNV total area and leakage area, the incidence rate of first sustained gain of 15 letters or more decreased. CONCLUSIONS: This post hoc analysis provided additional evidence for the role of baseline CNV features (CNV type, total area, and leakage area) in influencing visual and anatomic outcomes in eyes with nAMD after anti-VEGF treatment.

Evaluating a Technology-Mediated HPV Vaccination Awareness Intervention: A Controlled, Quasi-Experimental, Mixed Methods Study.

College-aged women and men are an important catch-up population for human papillomavirus (HPV) vaccination interventions. Limited research has explored technology-mediated HPV vaccination awareness interventions aimed at college students. The purpose was to evaluate a novel, technology-mediated, social media-based intervention to promote HPV vaccination among college students. A controlled, quasi-experimental, mixed methods study examined the feasibility of a technology-based intervention among two undergraduate classes (n = 58) at a public university in the southeastern United States of America. Classes were randomized to receive one of two cancer prevention programs (i.e., HPV vaccination (intervention) or healthy weight (control)). Both programs contained eight technology-mediated sessions, including weekly emails and private Facebook group posts. Participants completed pre-/post-test surveys and submitted weekly qualitative reflections. Data were analyzed using descriptive statistics and thematic review for qualitative data. Knowledge improved among participants in the HPV vaccination intervention relative to those in the control condition. Participants (97%) interacted on Facebook by "liking" a post or comment or posting a comment. Participants demonstrated robust engagement and high treatment satisfaction. Results suggests that social media is an effective platform to reach college students with health promotion interventions and increase HPV vaccination awareness in this important catch-up population.

Social Cost of Blindness Due to AMD and Diabetic Retinopathy in the United States in 2020.

BACKGROUND AND OBJECTIVE: To estimate the social cost of blindness due to wet age-related macular degeneration (wAMD), diabetic macular edema (DME), and proliferative diabetic retinopathy (PDR) in the United States in 2020. PATIENTS AND METHODS: Excess costs that occur because of blindness were estimated as the difference in costs in blind versus non-blind individuals. Per-patient costs were aggregated using the number of cases of blindness due to wAMD, DME, and PDR projected in 2020. RESULTS: Associated annual excess direct costs, indirect costs, and quality-adjusted life year loss per blind individual were $4,944, $54,614, and 0.214, respectively. Combining estimates with 246,423 projected cases of blindness due to wAMD, DME, and PDR translated to total societal costs of $20 billion in 2020, estimated to triple by 2050. CONCLUSION: Excess social costs associated with blindness in individuals with wAMD, DME, and PDR are substantial, with more than half of the burden attributed to indirect costs.

Punctum and canalicular anatomy for hydrogel-based intracanalicular insert technology.

Aim: Despite advances in cataract surgery, postoperative ocular inflammation and pain occurs. To address compliance issues with topical corticosteroid administration, a hydrogel-based dexamethasone insert was developed for intracanalicular administration. The objective is to understand the anatomy to best administer the insert and learn how the anatomy and hydrogel properties help retain the insert in the canaliculus over time. Materials & methods: Human cadavers (n = 5) were dissected to assess dimensions of punctum and canaliculus as part of drug discovery and development. Results & conclusions: Mean measures for punctal diameter was 0.5 ± 0 mm and vertical canaliculi length was 2.4 ± 0.5 mm and width was 1.6 ± 0.5 mm. Vertical canalicular width was larger than the punctal opening, a critical understanding for placing and retaining intracanalicular inserts.

Examining Breast Cancer Screening Behavior Among Southern Black Women After the 2009 US Preventive Services Task Force Mammography Guideline Revisions.

Updated United States Preventive Services Task Force (USPSTF) and American Cancer Society mammography screening recommendations push for increased age of initiation and lengthened breast cancer screening intervals. These changes have implications for the reduction of breast cancer mortality in Black women. The purpose of this study was to examine breast cancer screening behavior in a cohort of Southern Black women after the release of the 2009 USPSTF recommendations. Surveys assessing cancer screening information were collected from members of Black churches between 2006 and 2013. The sample was restricted to women aged 40 to 74 years, who did not report a breast cancer diagnosis, or a recent diagnostic mammogram (n = 789). Percentages of women ever completing a mammogram (age 40-49) and annual mammography (age 50-74) in 2006-2009 and 2010-2013 were compared using chi-square statistics. Logistic regression models were fit to determine the predictors of adherence to pre-2010 screening guidelines. No significant changes in mammography rates were found for women in the 40-49 age group (X2 = 0.42, p = 0.52) nor for those in the 50-74 age group (X2 = 0.67, p = 0.41). Completing an annual clinical breast exam was a significant predictor of adherence to pre-2010 screening guidelines for both age groups (OR 19.86 and OR 33.27 respectively) and participation in education sessions (OR 4.26). Stability in mammography behavior may be a result of PCP's advice, or community activities grounded pre-2010 screening recommendations. More research is needed to understand how clinical interactions and community-based efforts shape Black women's screening knowledge and practices.

Higher-Order Assessment of OCT in Diabetic Macular Edema from the VISTA Study: Ellipsoid Zone Dynamics and the Retinal Fluid Index.

PURPOSE: To investigate retinal fluid features and ellipsoid zone (EZ) integrity dynamics on spectral-domain OCT (SD-OCT) in eyes with diabetic macular edema (DME) treated with intravitreal aflibercept injection (IAI) in the VISTA-DME study. DESIGN: A post hoc subanalysis of a phase III, prospective clinical trial. PARTICIPANTS: Eyes received either IAI 2 mg every 4 weeks (2q4) or every 8 weeks after 5 initial monthly doses (2q8). METHODS: All eyes from the VISTA Phase III study in the IAI groups imaged with the Cirrus HD-OCT system (Zeiss, Oberkochen, Germany) were included. The OCT macular cube datasets were evaluated using a novel software platform to generate retinal layer and fluid boundary lines that were manually corrected for assessment of change in EZ parameters and volumetric fluid parameters from baseline. The retinal fluid index (i.e., proportion of the retinal volume consisting of cystic fluid) was also calculated at each time point. MAIN OUTCOME MEASURES: The feasibility of volumetric assessment of higher-order OCT-based retinal parameters and its correlation with best-corrected visual acuity (BCVA). RESULTS: Overall, 106 eyes of 106 patients were included. Specifically, 52 eyes of 52 patients were included in the IAI 2q4 arm, and 54 eyes of 54 patients were included in the IAI 2q8 arm. Ellipsoid zone integrity metrics significantly improved from baseline to week 100, including central macular mean EZ to retinal pigment epithelium (RPE) thickness (2q4: 26.6 µm to 31.6 µm, P < 0.001; 2q8: 25.2 µm to 31.4 µm, P < 0.001). At week 100, central macular intraretinal fluid volume was reduced by >65% (P < 0.001) and central macular subretinal fluid volume was reduced by >99% in both arms (P < 0.001). Central macular retinal fluid index (RFI) significantly improved in both arms (2q4: 17.9% to 7.2%, P < 0.001; 2q8: 19.8% to 4.2%, P < 0.001). Central macular mean EZ-RPE thickness (i.e., a surrogate for photoreceptor outer segment length) and central RFI were independently correlated with BCVA at multiple follow-up visits. CONCLUSIONS: Intravitreal aflibercept injection resulted in significant improvement in EZ integrity and quantitative fluid metrics in both 2q4 and 2q8 arms and correlated with visual function.

Engaging Patients and Clinicians in Online Reporting of Adverse Effects During Chemotherapy for Cancer: The eRAPID System (Electronic Patient Self-Reporting of Adverse Events: Patient Information and aDvice).

INTRODUCTION: During cancer treatment the timely detection and management of adverse events is essential for patient safety and maintaining the quality of life. Electronic patient self-Reporting of Adverse events: Patient Information and aDvice (eRAPID) was devised to support oncology practice, by allowing patients to self-report symptoms online at home during and beyond cancer treatment. Fundamentally the eRAPID intervention delivers immediate severity-tailored feedback directly to patients to guide self-management strategies or hospital contact. Patient data are available in electronic health records for hospital staff to access and review as part of clinical assessments. METHODS FOR INTERPRETING AND ADDRESSING PATIENT-REPORTED OUTCOME (PRO) SCORES:: The eRAPID intervention has 5 main interconnecting components (clinical integration into standard care pathways, patient symptom reports, self-management advice, information technology, and staff/patient training). Following guidance for the development of complex interventions and using a mixed methods approach, eRAPID was created through a number of stages and tested in a series of usability settings before undergoing systematic evaluation in a randomized controlled trial. These developmental stages are described here with a focus on how decisions were made to enhance patient and professional engagement with symptom reports and encourage interpretation and clinical utilization of the data. DISCUSSION: Clinically embedded PRO interventions involve a number of elements and stakeholders with different requirements. Following extensive developmental work eRAPID was pragmatically designed to fit into current oncology practices for reviewing and managing chemotherapy-related toxicities.

Difference in Treatment Effect Between Intravitreal Aflibercept Injection and Laser by Baseline Factors in Diabetic Macular Edema.

BACKGROUND AND OBJECTIVE: To evaluate the effect of baseline factors on differences in vision gains with intravitreal aflibercept injection (IAI) versus laser control in patients with diabetic macular edema (DME). PATIENTS AND METHODS: This was an integrated post-hoc subanalysis of two phase 3 trials (VISTA, VIVID) in patients with DME. Least square (LS) mean differences of patients treated with IAI compared to laser control in best-corrected visual acuity (BCVA) change from baseline at week 100 were evaluated for association with baseline demographics and baseline systemic disease characteristics. RESULTS: At week 100, LS mean differences in BCVA change from baseline with IAI compared to laser control were not significant for association with baseline age, gender, and race or status of glycosylated hemoglobin, body mass index, renal impairment, hypertension, cerebrovascular disease, and ischemic heart disease. CONCLUSION: Vision gains with IAI were significantly greater than laser control and were not influenced by demographics and systemic disease control at baseline.

Online tool for monitoring adverse events in patients with cancer during treatment (eRAPID): field testing in a clinical setting.

OBJECTIVES: Electronic patient self-Reporting of Adverse-events: Patient Information and aDvice (eRAPID) is an online system developed to support patient care during cancer treatment by improving the detection and management of treatment-related symptoms. Patients can complete symptom reports from home and receive severity-based self-management advice, including notifications to contact the hospital for severe symptoms. Patient data are available in electronic records for staff to review. Prior to the commencement of a randomised controlled trial (RCT), field testing of the intervention was undertaken to troubleshoot practical issues with intervention integration in clinical practice. DESIGN: Observational clinical field testing. SETTING: Medical oncology breast service in a UK cancer centre. PARTICIPANTS: 12 patients receiving chemotherapy for early breast cancer and 10 health professionals (oncologists and specialist nurses). INTERVENTION: Patients were asked to use the eRAPID intervention and complete weekly online symptom reports during four cycles of chemotherapy. Clinical staff were invited to access and use patient data in clinical assessments. ANALYSIS: Descriptive data on the frequency of online symptom report completion and severe symptom notifications were collated. Verbal and written feedback was collected from patients and staff and semistructured interviews were conducted to explore patient experiences. Interviews were transcribed and analysed thematically. RESULTS: The testing ran from January 2014 to March 2014. Feedback from patients and staff was largely positive. Patients described eRAPID as 'reassuring' and 'comforting' and valued the tailored management advice. Several changes were made to refine eRAPID. In particular, improvement of the clinical notification, patient reminder systems and changes to patient and staff training. CONCLUSIONS: The field testing generated valuable results used to guide refinement of eRAPID prior to formal intervention evaluation. Feedback indicated that eRAPID has the potential to improve patients' self-efficacy, knowledge and confidence with managing symptoms during treatment. A large-scale RCT is underway with data collection due to finish in October 2018.

Extended (Every 12 Weeks or Longer) Dosing Interval With Intravitreal Aflibercept and Ranibizumab in Neovascular Age-Related Macular Degeneration: Post Hoc Analysis of VIEW Trials.

PURPOSE: To evaluate outcomes and disease characteristics in eyes with neovascular age-related macular degeneration that received intravitreal aflibercept injection (IAI) and ranibizumab every 12 weeks or longer (≥q12 weeks) or less than every 12 weeks (

Intravitreal Aflibercept Versus Ranibizumab for Wet Age-Related Macular Degeneration: A Cost-Effectiveness Analysis.

BACKGROUND: Age-related macular degeneration (AMD) is the leading cause of vision loss in the United States. The most severe vision loss occurs in patients with neovascular AMD, known as wet AMD (wAMD). The most commonly used antivascular endothelial growth factor (VEGF) therapies approved by the FDA to treat patients with wAMD are ranibizumab, 0.5 mg administered by intravitreal injection once a month (approximately every 28 days), and intravitreal aflibercept injection (IAI), 2 mg every 4 weeks (monthly) for the first 12 weeks (3 months), followed by IAI 2 mg once every 8 weeks (2 months). Given the similar efficacy and safety profiles between IAI and ranibizumab, their associated costs and comparative cost-effectiveness are key factors in determining which one represents a more rational investment of scarce health care resources to help address the increasing cost of prescription drugs in the United States, a source of concern for patients, prescribers, payers, and policymakers. OBJECTIVE: To assess the cost-effectiveness of intravitreal aflibercept injection 2 mg every 8 weeks after 3 initial monthly doses (IAI 2q8) versus ranibizumab 0.5 mg monthly (Rq4) and pro re nata (PRN) in the treatment of patients with wAMD from a U.S. payer perspective. METHODS: A Markov cohort model was developed to estimate the lifetime quality-adjusted life-years (QALYs) and costs of treating patients with wAMD with IAI 2q8, Rq4, and ranibizumab PRN. The model considered changes in best-corrected visual acuity in the affected and fellow eyes over time, and the effect of blindness on mortality. Efficacy for IAI 2q8 and Rq4 was from VIEW 1 and VIEW 2 studies and from the Comparison of AMD Treatments Trials for ranibizumab PRN. Utilities and costs (in 2016 U.S. dollars) were from published literature. Health outcomes and costs were discounted at an annual rate of 3%. RESULTS: Over a lifetime, IAI 2q8 provided equal health benefits with Rq4 (5.44 QALYs) at a lower total cost ($33,745 vs. $48,031) as a result of fewer injections. IAI 2q8 yielded slightly greater QALYs versus ranibizumab PRN (5.44 vs. 5.40) at a slightly higher cost ($33,745 vs. $33,652), with an incremental cost per QALY gained of $2,583. Results were sensitive to variations in drug acquisition costs and number of injections of both drugs and the baseline age of the cohort. CONCLUSIONS: IAI 2q8 can be cost saving and cost-effective compared with Rq4 and ranibizumab PRN for the treatment of wAMD in the United States. DISCLOSURES: This study was funded by Regeneron Pharmaceuticals, the manufacturer of aflibercept. Hernandez, Lanitis, Cele, and Toro-Diaz are employed by Evidera, which received funding from Regeneron Pharmaceuticals to conduct this study. Gibson and Kuznik are employed by and own stock in Regeneron Pharmaceuticals.

Differential Response to Anti-VEGF Regimens in Age-Related Macular Degeneration Patients with Early Persistent Retinal Fluid.

PURPOSE: To compare the effect of intravitreal aflibercept or ranibizumab drug type and frequency on visual acuity outcomes in eyes with neovascular age-related macular degeneration (NVAMD) and early persistent retinal fluid after 3 initial monthly injections. DESIGN: A post hoc analysis of eyes enrolled in VIEW 1 and VIEW 2, 2 similarly designed, randomized, phase 3 trials. PARTICIPANTS: A total of 1815 eyes with NVAMD from VIEW 1 and VIEW 2. METHODS: Analyses included patients with known fluid status at baseline and weeks 4, 8, and 12 in 3 treatment groups: ranibizumab 0.5 mg every 4 weeks (Rq4) (n = 595), intravitreal aflibercept injection (IAI) 2 mg every 4 weeks (2q4) (n = 613), and IAI 2 mg every 8 weeks (2q8) after 3 monthly injections (n = 607). MAIN OUTCOME MEASURES: Mean best-corrected visual acuity (BCVA) change from baseline over weeks 16 to 52 and the proportion of eyes that gained ≥15 letters or lost ≥5 letters were evaluated in eyes with and without persistent fluid (cystic intraretinal or subretinal fluid at all 4 initial visits). Visual outcomes also were assessed in eyes with persistent fluid by fluid type (intraretinal and subretinal fluid). RESULTS: The proportions of eyes with persistent fluid were 29.4%, 18.8%, and 20.3% in the Rq4, 2q4, and 2q8 groups, respectively. In these eyes, mean BCVA gain from baseline to week 52 was greater with 2q4 compared with Rq4 (P < 0.01) and 2q8 (P < 0.05), whereas it was similar with Rq4 and 2q8 (P = 0.294). At week 52, similar proportions of eyes gained ≥15 letters (31.5%-35.2%), whereas fewer eyes lost ≥5 letters with 2q4 compared with Rq4 and 2q8 (6.5% vs. 16.6% and 16.2%). The pattern of visual outcomes was similar regardless of fluid type. In eyes without persistent fluid, BCVA changes were similar across treatment groups. CONCLUSIONS: In patients with early persistent fluid, 2q4 may provide additional clinical benefit over 2q8 or Rq4.
