ABSTRACT

BACKGROUND: The Advancing Inclusive Research (AIR) Site Alliance is composed of clinical research centers that partner with Genentech, a biotechnology company, to advance the representation of diverse patient populations in its oncology and ophthalmology clinical trials, test recruitment, and retention approaches and establish best practices to leverage across the industry to achieve health equity. METHODS: Through a data-driven selection process, Genentech identified 6 oncology and 3 ophthalmology partners that focus on reaching historically underrepresented patients in clinical trials and worked collaboratively to share knowledge and explore original ways of increasing clinical study access for every patient, including sites co-creation of a Protocol Entry Criteria Guideline with inclusion principles. RESULTS: For patients, three publicly available educational videos about clinical trials were created in multiple languages. The AIR Site Alliance has also defined invoiceable services for sites to enhance patient support; this has been built into the new study budget templates for sustainability. For healthcare professionals (HCPs), the first-of-its-kind AIR Educational Program was developed to focus on identifying and addressing bias and engaging historically underrepresented patient populations in trials. The sites also co-created videos for HCPs and patients on why advancing inclusive research matters. Over 16 regional health equity symposia have been delivered for patients, HCPs, and community leaders. CONCLUSIONS: This AIR Site Alliance is a model for other site alliances, including Kenya, South Africa, the United Kingdom, and Canada. Such alliances will build a robust and sustainable research ecosystem that includes diverse patient groups and encourages change across the healthcare system.

ABSTRACT

PURPOSE: To evaluate long-term visual acuity (VA) and performance of a monitoring strategy with a self-operated artificial-intelligence-enabled home monitoring system in conjunction with standard care for early detection of neovascular age-related macular degeneration (nAMD). DESIGN: Retrospective review. SUBJECTS: Patients with dry-age-related macular degeneration from 5 referral clinics. METHODS: Clinical data of patients monitored with ForeseeHome (FSH) device from August 2010 to July 2020 were reviewed. MAIN OUTCOME MEASURES: Visual acuity at baseline, VA at diagnosis of nAMD for eyes that converted while monitored, and VA from the final study follow-up, weekly frequency of use, duration of monitoring, modality of conversion diagnosis (system alert vs. detection by other standard care means), and duration and number of treatments since conversion to final study follow-up were collected. RESULTS: We reviewed 3334 eyes of 2123 patients with a mean (standard deviation [SD]) age of 74(8) years, monitored for a mean (SD) duration of 3.1 (2.4) years, with a total of 1 706 433 tests in 10 474 eye-monitoring years. The mean (SD) weekly use per patient was 5.2 (3.4), and it was persistent over the usage period. Two hundred eighty-five eyes converted while monitored at an annual rate of 2.72% and were treated with a mean (SD) 17.3 (16.5) injections over a mean (SD) 2.7 (2.0) years, with 6.4 (3.1) injections per year for eyes treated for > 1 year. The median VAs at baseline and at final follow-up for eyes that did not convert were 20/27 and 20/34 with a median change of 0.0 letters. The median VAs at baseline, conversion, and final follow-up for eyes that converted during the monitoring period were 20/30, 20/39, and 20/32 with a median change from baseline to conversion, baseline to recent, and conversion to recent of -4, -4, and 0 letters, respectively. Fifty-two percent of conversions detected had a system alert before conversion. Forty-eight percent of patients were detected by symptoms or routine visit. Patients experienced a non-nAMD alert on average every 4.6 years. At conversion and at final follow-up, the proportion (95% CI) of eyes that maintained ≥ 20/40 was 84% (78% to 88%) and 82% (76% to 86%), respectively. CONCLUSIONS: Patients in the FSH monitoring program showed excellent long-term VA years after conversion to nAMD.

ABSTRACT

OBJECTIVE: The purpose of this study is to determine if ziv-aflibercept is a safe and effective maintenance drug for nAMD. STUDY DESIGN AND METHODS: This is a randomized, prospective, single-blinded trial. Inclusion criteria were active nAMD, prior anti-VEGF treatment, and BCVA ≤20/200. The treatment group received ziv-aflibercept. The control group continued their existing anti-VEGF regimen. The main outcome measures were BCVA, CFT, and safety. RESULTS: Mean baseline BCVA was 1.58 ± 0.44 logMAR and 1.71 ± 0.39 logMAR in the control (n = 27) and treatment (n = 29) groups, respectively. After 24 months, the mean change in BCVA was 0.11 in the control group (equivalent to a loss of 5 ETDRS letters) and 0.01 logMAR in the treatment group (p = .48). Baseline CFT was 257 ± 33 µm and 247 ± 30 µm in the control and treatment groups, respectively, and after 24 months mean change in CFT was 26 µm and -5 µm (p = .24). There were no ocular or systemic adverse events during the study. CONCLUSION: Ziv-aflibercept is a safe and effective as a maintenance drug for patients with nAMD. It may represent a cost-effective alternative to aflibercept and second-line therapy for eye resistant bevacizumab or ranibizumab.

ABSTRACT

We present a case of a patient that experienced severe hemorrhagic occlusive retinal vasculitis secondary to injection of 1.0 mg/0.1 ml of intracameral vancomycin for endophthalmitis prophylaxis after an uneventful cataract surgery. The case is especially unique in that our patient ended up maintaining 20/25 vision with an ocular disease that is typically visually threatening. This may be due to the aggressive administration of periocular and oral steroids combined with scheduled anti-VEGF injections that were later transitioned into a treat and extend regimen.

ABSTRACT

PURPOSE: To quantify differences in the age, gender, race, and clinical complexity of Medicare beneficiaries treated by ophthalmologists and optometrists in each of the United States. DESIGN: Cross-sectional study based on publicly accessible Medicare payment and utilization data from 2012 through 2017. METHODS: For each ophthalmic and optometric provider, demographic information of treated Medicare beneficiaries was obtained from the Medicare Provider Utilization and Payment Data from the Centers for Medicare and Medicaid Services (CMS) for the years 2012 through 2017. Clinical complexity was defined using CMS Hierarchical Condition Category (HCC) coding. RESULTS: From 2012 through 2017, ophthalmologists in every state treated statistically significantly older beneficiaries, with the greatest difference (4.99 years in 2014) between provider groups seen in Rhode Island. In most states there was no gender difference among patients treated by the providers but in 46 states ophthalmologists saw a more racially diverse group of beneficiaries. HCC risk score analysis demonstrated that ophthalmologists in all 50 states saw more medically complex beneficiaries and the differences were statistically significant in 47 states throughout all six years. CONCLUSIONS: Although there are regional variations in the characteristics of patients treated by ophthalmologists and optometrists, ophthalmologists throughout the United States manage older, more racially diverse, and more medically complex Medicare beneficiaries.

ABSTRACT

Aim: Evaluate the cost-effectiveness of ocriplasmin in symptomatic vitreomacular adhesion (VMA) with or without full-thickness macular hole ≤400 µm versus standard of care. Methods: A state-transition model simulated a cohort through disease health states; assignment of utilities to health states reflected the distribution of visual acuity. Efficacy of ocriplasmin was derived from logistic regression models using Ocriplasmin for Treatment for Symptomatic Vitreomacular Adhesion Including Macular Hole trial data. Model inputs were extracted from Phase III trials and published literature. The analysis was conducted from a US Medicare perspective. Results: Lifetime incremental cost-effectiveness ratio was US$4887 per quality-adjusted life year gained in the total population, US$4255 and US$10,167 in VMA subgroups without and with full-thickness macular hole, respectively. Conclusion: Ocriplasmin was cost effective compared with standard of care in symptomatic VMA.

ABSTRACT

Background: Age-related macular degeneration is the leading cause of blindness in adults over the age of 50 in the United States of America. Neovascular age-related macular degeneration (nAMD) is sight-threatening, but can be treated by three currently utilized, intravitreally administered drugs: aflibercept, bevacizumab, and ranibizumab. Ziv-aflibercept is an analogue of aflibercept, containing the same active molecule in a different buffer solution, and its recent availability has prompted numerous pre-clinical and clinical trials addressing its viability for intraocular use, summarized herein. Results: Trial outcomes demonstrate that ziv-aflibercept has a similar safety profile to other indicated drugs with effective maintenance or improvement of best-corrected visual acuity (BCVA) and reduction of retinal fluid or central foveal thickness (CFT). Clinical trials of ziv-aflibercept in other neovascular disorders such as diabetic macular edema (DME) and retinal vein occlusion (RVO) have shown similar results. Conclusion: Further prospective, randomized studies of ziv-aflibercept are needed, particularly in eyes with nAMD.

ABSTRACT

BACKGROUND AND OBJECTIVE: The purpose of this study is to provide an updated assessment of cost-efficacy of intravitreal ocriplasmin (IVO) for vitreomacular adhesion (VMA) and macular holes (MH). PATIENTS AND METHODS: This was a single-center, multiple-physician, institutional review board-approved, retrospective, 15-month cost-effectiveness analysis study (January 2015 to April 2016). Clinical charts and billing records of 247 patients with VMA and MH were reviewed. Patients were divided into group 1 (VMA and MH treated by pars plana vitrectomy [PPV]), group 2 (VMA and MH treated by IVO), and group 3 (VMA treated by IVO). Success rates of interventions in each group were compared, including cost-effectiveness, cost per line-year, and cost per quality-adjusted life-year (QALY). RESULTS: Success rates for initial intervention were 98% in group 1, 55.6% in group 2, and 67.7% in group 3. Cost of PPV at our institution was $6,538.00 and cost of IVO (2016) was $3,480.00. Using a cohort-based computer Markov model, the treatment decision tree demonstrated group 1 was less cost-effective, with cost per line of $2,654.39, cost per line-year saved of $185.62, and cost per QALY of $6,187.00. Group 2 was cost-effective with cost per line of $2,456.25, cost per line-year saved of $171.77, and cost per QALY of $5,726.00. The difference in cost-effectiveness showed IVO was more cost-effective than PPV, with a difference in cost per line of $198.14, cost per line-year saved of $13.85, and cost per QALY of $461.00. CONCLUSIONS: IVO is a more cost-effective intervention than vitrectomy for the treatment of VMA and MH in the setting of judicious use in appropriate patients. The success rate of IVO in our patient population was greater than currently published rates and most certainly impacted probability of cost-efficacy. Further research targeting optimizing IVO success rate is needed. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e240-e248.].

ABSTRACT

INTRODUCTION: The purpose of this project was to evaluate the role of MR antagonists as an adjunct in patients with neovascular age-related macular degeneration (AMD) who have chronic subretinal fluid. METHODS: Inclusion criteria were patients with a diagnosis of neovascular AMD, who had completed at least six anti-VEGF injections, and had persistent subretinal fluid (SRF) on optical coherence tomography (OCT). Treatment with oral eplerenone was initiated and dose titrated according to protocol. RESULTS: 23 patients were included in the study (mean age = 54.6, 52.2% female, 47.8% male). 13 of the 23 patients had predominantly chronic subretinal fluid without large PEDs. In this subgroup, mean initial central macular thickness (CMT) prior to starting oral eplerenone was 305.3 µm, and mean injection interval was 40.25 days. Mean final CMT after at least 3 months of adjunctive eplerenone treatment was 240.6 µm and mean injection interval with adjunctive treatment was 54.61 days. Mean extension of the injection interval after commencing oral eplerenone was 14.36 days. CONCLUSIONS: These findings suggest oral MR antagonists may have a role as an adjunctive treatment in neovascular AMD, and may be particularly useful in dehydration of the subretinal space in the setting of chronic subretinal fluid. Further research is needed in randomized controlled trials to elucidate the precise role of oral MR antagonists in neovascular AMD.

ABSTRACT

PURPOSE: To report the first case to our knowledge of intravitreal daptomycin used to successfully treat culture-negative vancomycin resistant to exogenous endophthalmitis. METHODS: Case report with preoperative, intraoperative, and postoperative findings. RESULTS: A 63-year-old Caucasian male underwent routine pars plana vitrectomy with epiretinal membrane peeling. He developed acute postoperative endophthalmitis, and underwent vitreous tap and injection of intravitreal vancomycin/ceftazidime/dexamethasone. Gram stain showed Gram-positive cocci, but cultures were negative. His infection subsequently proved very recalcitrant and his treatment course involved pars plana vitrectomy with anterior chamber washout and repeat injection of antibiotics, followed by repeat intravitreal vancomycin and ceftazidime. Ultimately, a second vitrectomy with intravitreal daptomycin controlled his intraocular infection. On each occasion, cultures were negative. CONCLUSION: This case suggests that vancomycin resistance should be considered in culture-negative postoperative endophthalmitis, and intravitreal daptomycin should be considered as an important treatment alternative. Although vancomycin resistance is fairly rare in endophthalmitis, acknowledgment of its increasing occurrence rate is critical for optimal management.

ABSTRACT

BACKGROUND AND OBJECTIVE: Overaction of mineralocorticoid receptor (MR) pathways has been implicated in the pathophysiology of central serous chorioretinopathy (CSCR). The purpose of this study was to evaluate MR antagonists in the treatment of CSCR. STUDY DESIGN AND METHODS: A retrospective chart review was conducted of all CSCR patients at one center treated with spironolactone or eplerenone (50 mg p.o. b.i.d.) or observation. Patients were followed at monthly intervals with examination and optical coherence tomography. RESULTS: 32 patients (12 eplerenone, 12 spironolactone, 8 observation) were enrolled in the study. Both MR antagonists demonstrated statistically significant visual acuity improvement and subretinal fluid reduction at 1, 2, and 3 months compared to baseline (p < 0.05). 58.3% of patients had complete resolution of subretinal fluid at 2 months on MR antagonists, compared to 12.5% under observation (p < 0.05). Photodynamic therapy was used to treat refractory subretinal fluid past 6 months in 1/24 (4.2%) on MR antagonists and 2/8 (25%) patients under observation. There was no difference in efficacy between eplerenone and spironolactone. Spironolactone exhibited increased side effects (8/12, 75%) compared to eplerenone (3/12, 25%; p < 0.05). CONCLUSIONS: This data supports the use of MR antagonists in CSCR and suggests an accelerated improvement compared to observation. Prospective randomized trials are needed to better elucidate the precise role of MR antagonists in the management of CSCR.

ABSTRACT

Overactivation of mineralocorticoid receptor pathways has been implicated in the pathophysiology of central serous chorioretinopathy (CSCR). Recently, mineralocorticoid receptor antagonists such as eplerenone have demonstrated success in treating subretinal fluid in CSCR. This case demonstrates a patient who was initially presumed to have subretinal fluid secondary to CSCR and was started on a trial of oral eplerenone. It quickly became evident that her subretinal fluid was secondary to a peripapillary polypoidal choroidal vasculopathy network, but she demonstrated a significant improvement with oral eplerenone. To the authors' knowledge, this is the first case of eplerenone use to treat polypoidal choroidal vasculopathy.
