Longitudinal Retinal Perfusion Status in Eyes with Diabetic Macular Edema Receiving Intravitreal Aflibercept or Laser in VISTA Study.

PURPOSE: To evaluate changes in retinal perfusion status with intravitreal aflibercept injection (IAI) and laser treatment in the phase 3 VISTA study of patients with diabetic macular edema (DME). DESIGN: Post hoc analysis of a double-masked, randomized, active-controlled, phase 3 trial. PARTICIPANTS: Patients with center-involved DME in the study eye. METHODS: VISTA randomized 466 patients to laser, IAI 2 mg every 4 weeks (2q4), or IAI 2 mg every 8 weeks after 5 monthly doses (2q8). One eye per patient was enrolled in the study. Retinal perfusion status was evaluated by fluorescein angiography based on the presence or absence of retinal nonperfusion (RNP) in quadrants intersecting at the optic nerve head by a masked independent reading center at weeks 24, 52, 72, and 100. Visual and anatomic outcomes were evaluated at all visits. In patients who received rescue treatment, data were censored from the time rescue treatment was given. MAIN OUTCOME MEASURES: Change in perfusion status from baseline through week 100. RESULTS: At week 100, the proportion of eyes with improvement in retinal perfusion (defined as a reduction from baseline in the total number of quadrants in which RNP is present) in the laser control, 2q4, and 2q8 groups was 14.6%, 44.7%, and 40.0%, respectively. The proportion of eyes that experienced worsening in retinal perfusion (defined as an increase from baseline in the total number of quadrants in which RNP is present) at week 100 in the laser control, 2q4, and 2q8 groups was 25.0%, 9.0%, and 8.6%, respectively. CONCLUSION: Post hoc analysis of the phase 3 VISTA study in patients with DME provides evidence that regular IAI dosing not only can slow worsening of retinal perfusion associated with diabetic retinopathy but also may be able to improve retinal perfusion in some cases by decreasing zones of RNP.

Impact of Age on the Efficacy and Safety of Alirocumab in Patients with Heterozygous Familial Hypercholesterolemia.

PURPOSE: This post-hoc analysis examined whether age modified the efficacy and safety of alirocumab, a PCSK9 inhibitor, in patients with heterozygous familial hypercholesterolemia (HeFH), using pooled data from four 78-week placebo-controlled phase 3 trials (ODYSSEY FH I, FH II, LONG TERM, and HIGH FH). METHODS: Data from 1257 patients with HeFH on maximally tolerated statin ± other lipid-lowering therapies were analyzed by an alirocumab dose regimen and by age subgroups (18 to < 45, 45 to < 55, 55 to < 65, and ≥ 65 years). In the FH I and II trials, patients received 75 mg subcutaneously every 2 weeks (Q2W), with dose increase to 150 mg Q2W at week 12 if week 8 low-density lipoprotein cholesterol (LDL-C) was ≥ 70 mg/dl. In HIGH FH and LONG TERM, patients received 150 mg alirocumab Q2W. RESULTS: Baseline characteristics were similar between treatment groups across all age groups; the proportion of males decreased whereas the proportion of patients with coronary heart disease, diabetes, hypertension, and declining renal function increased with increasing age. Mean LDL-C reductions at week 24 were consistent across age groups (50.6-61.0% and 51.1-65.8% vs. placebo for the 75/150 and 150 mg alirocumab dose regimens, respectively; both non-significant interaction P-values). Treatment-emergent adverse events occurred in similar frequency in alirocumab- and placebo-treated patients regardless of age, except for injection-site reactions, which were more common in alirocumab than placebo but declined in frequency with age. CONCLUSIONS: Alirocumab treatment resulted in significant LDL-C reductions at weeks 12 and 24 and was generally well tolerated in patients with HeFH across all age groups studied.

Baseline Factors Affecting Changes in Diabetic Retinopathy Severity Scale Score After Intravitreal Aflibercept or Laser for Diabetic Macular Edema: Post Hoc Analyses from VISTA and VIVID.

PURPOSE: To evaluate whether select baseline systemic and ocular factors influence ≥2-step improvement in the Diabetic Retinopathy Severity Scale (DRSS) score at week 100 in VISTA and VIVID. DESIGN: Post hoc analysis of 2 similarly designed phase 3 trials, VISTA and VIVID. PARTICIPANTS: Total of 456 patients with center-involved diabetic macular edema (DME). METHODS: VISTA and VIVID randomized 872 DME patients to receive intravitreal aflibercept injection (IAI) 2 mg every 4 weeks (2q4), IAI 2 mg every 8 weeks after 5 monthly doses (2q8), or macular laser photocoagulation. This post hoc analysis evaluated the influence of select baseline factors on ≥2-step DRSS score improvement by logistic regression in an integrated VISTA and VIVID dataset using observed cases (n = 456) with patients in each treatment group divided into tertiles based on each characteristic. MAIN OUTCOME MEASURES: Proportion of patients with ≥2-step improvement in DRSS score from baseline at week 100 by age, duration of diabetes, hemoglobin A1c (HbA1c), body mass index (BMI), best-corrected visual acuity (BCVA), central subfield thickness (CST), and DRSS score. RESULTS: At week 100, 10.1%, 34.3%, and 37.6% of patients in the laser, 2q4, and 2q8 groups experienced a ≥2-step DRSS score improvement, respectively. Age, duration of diabetes, HbA1c, BMI, BCVA, and CST had no impact on the ability to achieve ≥2-step improvement in DRSS score. Initial DRSS score was the only factor significantly associated with ≥2-step DRSS score improvement in all treatment groups at weeks 24, 52, 76, and 100. Relatively higher proportions of IAI-treated patients with worse BCVA or thicker CST experienced ≥2-step DRSS score improvement compared with those with better BCVA or thinner CST, respectively, but these associations were not statistically significant. CONCLUSION: A strong association was present between baseline DRSS score and ≥2-step DRSS score improvement at week 100 for DME patients in VISTA and VIVID.

Correction to: Assessment of the 1% of Patients with Consistent < 15% Reduction in Low-Density Lipoprotein Cholesterol: Pooled Analysis of 10 Phase 3 ODYSSEY Alirocumab Trials.

The original version of this article unfortunately contained a mistake in the Discussion section.

Assessment of the 1% of Patients with Consistent < 15% Reduction in Low-Density Lipoprotein Cholesterol: Pooled Analysis of 10 Phase 3 ODYSSEY Alirocumab Trials.

PURPOSE: Clinical trials of statins and other lipid-lowering therapies (LLTs) often report large inter-individual variations in their effects on low-density lipoprotein cholesterol (LDL-C). We evaluated apparent hyporesponsiveness to the proprotein convertase subtilisin/kexin type 9 inhibitor alirocumab (defined as < 15% LDL-C reduction from baseline at all timepoints) using data from 10 Phase 3 trials (3120 hypercholesterolemic patients). METHODS: This report assessed the LDL-C percent reduction from baseline at weeks 4-104 (depending on study), and alirocumab serum levels and antidrug antibodies, in patients with apparent hyporesponsiveness. RESULTS: Among the 3120 patients evaluated, 98.9% responded to alirocumab, and 33 (1.1%) had < 15% LDL C reduction at all measured timepoints. Pharmacokinetics data indicated that 13/33 apparent hyporesponders had not received alirocumab; no pharmacokinetics data were available for 14/33, and 6/33 had detectable alirocumab. For the six patients with confirmed alirocumab receipt, the degree of adherence to pre-study concurrent LLTs could not be determined after study start; one of these patients had persistent antidrug antibodies. CONCLUSIONS: Apparent hyporesponsiveness to alirocumab appeared to be due to lack of receipt of alirocumab determined by serum alirocumab levels, possible lack of adherence to concurrent LLTs, a theoretical and rare possibility of biological non-responsiveness due to persistent antidrug antibodies, or other causes, as yet unidentified.

Comprehensive Review of Ocular and Systemic Safety Events with Intravitreal Aflibercept Injection in Randomized Controlled Trials.

PURPOSE: To assess the ocular and systemic safety of intravitreal aflibercept injection (IAI) compared with controls in IAI trials in neovascular age-related macular degeneration (nAMD), macular edema following central retinal vein occlusion (MEfCRVO), macular edema following branch retinal vein occlusion (MEfBRVO), and diabetic macular edema (DME). DESIGN: Comprehensive review of 10 phase II and III trials of IAI in retinal diseases. PARTICIPANTS: Patients were included from IAI trials in nAMD (CLEAR-IT 2 [52 weeks], VIEW 1 [96 weeks], VIEW 2 [96 weeks], VIEW 1 extension [208 weeks]); MEfCRVO (COPERNICUS [100 weeks], GALILEO [76 weeks]); MEfBRVO (VIBRANT [52 weeks]); and DME (DA VINCI [52 weeks], VIVID [100 weeks], VISTA [100 weeks]). METHODS: Rates were calculated as events/100 person-years at risk (PYR). When applicable, rate ratios (RRs) and 95% confidence intervals (CIs) were provided. MAIN OUTCOME MEASURES: Outcomes included rates for intraocular inflammation, endophthalmitis, serious adverse events (SAEs), wound-healing complications, hypertension (HTN), adjudicated Anti-Platelet Trialists' Collaboration (APTC)-defined arterial thromboembolic events (ATEs) (nonfatal myocardial infarction, nonfatal stroke, and vascular death), and death from all causes. RESULTS: More than 4000 patients contributed >7000 PYR. For all outcomes, there were no meaningful differences between evaluated adverse event rates for IAI and controls. Overall intraocular inflammation rates were 2.37 (control) and 2.06 (IAI); overall RR was 0.87 (95% CI, 0.61-1.27). Overall endophthalmitis rates were 0.52 (control) and 0.22 (IAI); overall RR was 0.42 (95% CI, 0.18-1.03). Overall SAE rates were 23.09 (control) and 20.80 (IAI); overall RR was 0.90 (95% CI, 0.80-1.02). Overall rates of wound-healing complications were 0.17 (control) and 0.15 (IAI); overall RR was 0.85 (95% CI, 0.24-3.86). Overall HTN rates were 14.87 (control) and 11.27 (IAI), with an overall RR of 0.76 (95% CI, 0.65-0.89); HTN rates were highest in MEfBRVO and lowest in nAMD. For adjudicated APTC-defined ATEs, rates were 2.04 (control) and 2.19 (IAI), with an RR of 1.07 (95% CI, 0.73-1.61). Overall death rates were 1.16 (control) and 1.49 (IAI); overall RR was 1.28 (95% CI, 0.80-2.15). CONCLUSIONS: Rates of selected ocular and systemic adverse events with IAI were similar to those of controls and similar across disease states in evaluated IAI trials. Intravitreal aflibercept injection was generally well tolerated in the patients evaluated.

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.

Intraocular Pressure in Patients with Neovascular Age-Related Macular Degeneration Receiving Intravitreal Aflibercept or Ranibizumab.

PURPOSE: To assess change in intraocular pressure (IOP) in patients with neovascular age-related macular degeneration (NVAMD) receiving intravitreal aflibercept injection (IAI) or ranibizumab in VEGF Trap-Eye: Investigation of Efficacy and Safety in Wet AMD (VIEW) 1 and 2 studies. DESIGN: Analyses from 2 randomized, active-controlled, phase III trials. PARTICIPANTS: A total of 2457 patients with NVAMD. METHODS: Patients received IAI 2 mg every (q) 4 weeks (2q4), 0.5 mg q4 weeks (0.5q4), 2 mg q8 weeks (after 3 monthly doses; 2q8), or ranibizumab 0.5 mg q4 weeks (Rq4) for 52 weeks. At week 52, patients were switched to a variable regimen requiring at least quarterly dosing and allowing interim injections based on anatomic and visual assessment. MAIN OUTCOME MEASURES: Pre-injection IOP was analyzed in study and uninjected fellow eyes from baseline to week 96. Prespecified end points included mean change in IOP from baseline and prevalence of a >21 mmHg and >10 mmHg increase in IOP from baseline. Cumulative incidence of sustained (at 2 consecutive visits) IOP >21 mmHg, a single event of IOP >25 mmHg, and sustained IOP increase from baseline (≥5 mmHg) was also evaluated. RESULTS: Mean IOP change from baseline over 96 weeks in all IAI groups was consistently lower than in the Rq4 group, and this finding was replicated in both trials. In an analysis integrating both studies, the proportion of study eyes with IOP >21 mmHg at week 96 was 20.2%, 14.2%, 12.1%, and 12.5% in Rq4, 2q4, 2q8, and 0.5q4, respectively. Reduction in risk, relative to Rq4, of having sustained IOP >21 mmHg over 96 weeks was 62% (95% confidence interval [CI], 36%-78%), 50% (95% CI, 19%-70%), and 69% (95% CI, 45%-84%) for 2q4, 2q8, and 0.5q4, respectively. Risk reduction in the IAI groups for a sustained IOP increase ≥5 mmHg was 31% (95% CI, 8%-48%), 38% (95% CI, 17%-54%), and 47% (95% CI, 27%-61%), respectively. In uninjected fellow eyes, only sustained IOP >21 mmHg events were higher in the Rq4 group compared with all IAI groups. CONCLUSIONS: Incidence of elevated IOP in eyes with NVAMD was lower in all IAI groups than in the ranibizumab group.

Geographic atrophy in patients receiving anti-vascular endothelial growth factor for neovascular age-related macular degeneration.

PURPOSE: To examine factors associated with the apparent growth of geographic atrophy (GA) in a consecutive series of eyes with treatment-naive neovascular age-related macular degeneration receiving intravitreal anti-vascular endothelial growth factor therapy on a treat-and-extend regimen. METHODS: This was a retrospective cohort study. Two independent graders identified areas of GA using near-infrared reflectance imaging and spectral domain optical coherence tomography (SD-OCT). Neovascular lesion subtypes were classified based on fluorescein angiography (FA) as occult choroidal neovascularization, classic choroidal neovascularization, retinal angiomatous proliferation, or mixed choroidal neovascularization, and by the anatomical classification system which utilizes FA and SD-OCT as Types 1 (sub-retinal pigment epithelium), 2 (subretinal), 3 (intraretinal), or mixed neovascularization. RESULTS: Ninety-one patients (94 eyes) fit the inclusion criteria, of which 52 eyes (55.3%) experienced apparent GA growth. The odds of developing apparent GA were significantly lower in Type 1 neovascularization compared to the other lesion types (P < 0.001). Using both FA and SD-OCT to classify neovascular age-related macular degeneration significantly improves the goodness of fit in the correlation between apparent GA growth and baseline neovascular lesion type (P < 0.001). CONCLUSION: Treatment-naive neovascular age-related macular degeneration eyes with Type 1 neovascularization at baseline were less likely to develop GA than eyes with other types. The correlation between apparent GA growth and subtype of neovascularization is stronger when lesions are classified with an anatomic grading that utilizes both FA and SD-OCT.

Intraocular pressure in patients with neovascular age-related macular degeneration switched to aflibercept injection after previous anti-vascular endothelial growth factor treatments.

PURPOSE: To assess for change in intraocular pressure (IOP) in neovascular age-related macular degeneration patients switched to aflibercept after receiving previous treatments of intravitreal bevacizumab or ranibizumab. METHODS: This is a retrospective chart review of the first 53 patients (53 eyes) treated with at least 2 injections of 2 mg in 0.05 mL of aflibercept by March 6, 2013, after at least 2 previous injections of 0.5 mg in 0.05 mL of ranibizumab with or without previous injections of 1.25 mg in 0.05 mL of bevacizumab. The analysis was restricted to the first such sequence within each patient. The last previous anti-vascular endothelial growth factor injection before the switch to aflibercept was ranibizumab in all cases included in the study. Each person served as his or her own control. The pre-aflibercept IOP in the before state (treatment with bevacizumab or ranibizumab) was the preinjection IOP measure before dilation at the visit of the first aflibercept injection. Statistical analysis was performed using Microsoft Excel. RESULTS: There were 41 patients who were first treated with ranibizumab followed by aflibercept and 12 patients treated with ranibizumab and bevacizumab followed by aflibercept. For each of these sequences, IOP in the treated eye during treatment with aflibercept (the after state) was computed in 3 different ways: the first IOP, the last IOP, and the mean IOP for the period when treated with aflibercept. The pooled data showed a mean pre-aflibercept (the before state) IOP of 14.87 that decreased to a mean first IOP of 14.57, mean last IOP of 13.79, and a mean IOP of 14.14 during aflibercept treatment. The inference is based on the pooled analysis. The 95% confidence interval for the differences (after minus before) were -0.30 (-1.12 to 0.52), -1.08 (-1.83 to -0.32), and -0.73 (-1.30 to -0.17) for the first, last, and mean IOPs, respectively. The corresponding P values were 0.46 for the first, 0.006 for the last, 0.01 for the mean IOP during the aflibercept treatment period. CONCLUSION: Intraocular pressure was found to be significantly lower in patients switched to aflibercept after previous treatments with ranibizumab and/or bevacizumab. Aflibercept may have a more favorable IOP safety profile in patients previously on other anti-vascular endothelial growth factor treatments.

Impact of Systemic Dipeptidyl Peptidase-4 Inhibitor Use in Diabetic Macular Edema.

BACKGROUND AND OBJECTIVE: To evaluate impact of baseline systemic dipeptidyl peptidase-4 (DPP-4) inhibitor use in diabetic macular edema (DME). PATIENTS AND METHODS: This was a post hoc exploratory analysis of previously completed randomized, controlled clinical trials (VISTA and VIVID) in patients with DME evaluating intravitreal aflibercept injection (IAI) every 4 weeks (2q4) or every 8 weeks (2q8) or macular laser photocoagulation. RESULTS: Overall, a small number of patients (12.2% [n = 35], 9.7% [n = 28], and 15.4% [n = 44]) in the laser control, 2q4, and 2q8 groups reported baseline DPP-4 inhibitor use. There were no differences in changes from baseline in best-corrected visual acuity, central subfield thickness, or rates of 2-or-greater-step improvement in Diabetic Retinopathy Severity Scale score based on DPP-4 inhibitor use within each treatment group. CONCLUSION: DPP-4 inhibitor use at baseline did not influence the magnitude of visual and anatomic benefit in patients with DME being treated with IAI or laser.

Changes in neovascular activity following fixed dosing with an anti-vascular endothelial growth factor agent over 52 weeks in the phase III VIEW 1 and VIEW 2 studies.

BACKGROUND/AIMS: To understand changes in disease activity as assessed by leakage and retinal fluid status in patients with neovascular age-related macular degeneration (nAMD) receiving fixed dosing with an anti-vascular endothelial growth factor (anti-VEGF) agent. METHODS: In the phase III VIEW 1 (NCT00509795) and VIEW 2 (NCT00637377) studies, eyes with nAMD were treated with intravitreal aflibercept or ranibizumab. Independent, masked reading centres determined the presence/absence of leakage (fluorescein angiography) and retinal fluid (optical coherence tomography) at baseline, week 24 and week 52. In this integrated, post hoc analysis of the VIEW studies, the relationship between leakage/fluid status and best-corrected visual acuity (BCVA) was assessed. The impact of baseline lesion type (predominantly classic (PC), minimally classic (MC), occult) was also evaluated. Data from all treatment groups were pooled. RESULTS: 2373 eyes were included in this analysis. At baseline, 95.4% of eyes presented with both leakage and fluid. By week 52, leakage and fluid were present in 16.0% of eyes. Mean BCVA gains at week 52 were numerically greater in eyes without leakage and fluid versus eyes with both leakage and fluid (10.3 vs 9.2 letters). At week 52, 11.6%, 15.3% and 20.1% of eyes with PC, MC and occult lesions, respectively, had both leakage and fluid present. CONCLUSION: In this post hoc analysis, fixed dosing with an anti-VEGF agent over 52 weeks eliminated disease activity (absence of both leakage and fluid) in most eyes. The effect of anti-VEGF treatment on leakage/fluid status favoured PC versus occult lesions.

Outcomes in Patients with Diabetic Macular Edema Requiring Cataract Surgery in VISTA and VIVID Studies.

PURPOSE: To evaluate the impact of cataract surgery on visual and anatomic outcomes in patients with diabetic macular edema treated with intravitreal aflibercept injection (IAI) or laser control and who did not require rescue therapy. DESIGN: Post hoc analysis of 2 phase 3 trials, Study of Intravitreal Aflibercept Injection in Patients with Diabetic Macular Edema (VISTA) and Intravitreal Aflibercept Injection in Vision Impairment Due to DME (VIVID). PARTICIPANTS: Fifty-four patients (laser treatment, n = 11; IAI, n = 43) who underwent cataract surgery during the study period. METHODS: In VISTA and VIVID, patients received IAI 2 mg every 4 weeks, IAI 2 mg every 8 weeks after 5 monthly doses, or laser control through week 100. Starting at week 24, if rescue treatment criteria were met, IAI patients received laser therapy, and laser therapy patients received IAI 2 mg every 8 weeks (after 5 monthly doses). Patients who received rescue treatment before cataract surgery were excluded. MAIN OUTCOME MEASURES: Best-corrected visual acuity (BCVA) and central retinal thickness (CRT) in the laser control and pooled IAI groups before and after cataract surgery. RESULTS: The cumulative incidence of cataract surgery did not depend on treatment group assignment (rate ratio, = 1.517; 95% confidence interval, 0.782-2.944; P = 0.2174). At the last study visit before surgery, BCVA was 62.2 and 56.9 letters and CRT was 342 µm and 301 µm in the laser control and IAI groups, respectively. At the first study visit after cataract surgery, BCVA was improved significantly in both the laser control and IAI groups to 73.5 letters (P = 0.010 compared with last visit before surgery) and 67.2 letters (P < 0.001 compared with last visit before surgery), respectively. Corresponding change in CRT was a modest increase to 364 µm (P > 0.05 compared with last visit before surgery) and 359 µm (P = 0.013 compared with last visit before surgery), respectively. CONCLUSIONS: Incidence of cataract surgery was similar in both treatment groups. Despite a modest worsening in CRT after cataract surgery, BCVA was improved in both treatment groups.

Alirocumab efficacy and safety by race and ethnicity: Analysis from 3 ODYSSEY phase 3 trials.

BACKGROUND: Differences in lipid and cardiovascular risk profiles have been observed in African-American/black (AA/B), white (W), and Hispanic/Latino (H/L) individuals. Efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, may vary by race and ethnicity and has not been analyzed. OBJECTIVE: This post hoc analysis evaluated alirocumab efficacy and safety vs control in 3 pooled ODYSSEY phase 3 trials (COMBO I, COMBO II, and LONG TERM) by race (AA/B [n = 154] vs W [n = 1982]) and ethnicity (H/L [n = 174] vs non-H/L [n = 3149]). METHODS: Patients with elevated low-density lipoprotein cholesterol (LDL-C) despite maximally tolerated statin received alirocumab (75 mg up to 150 mg every 2 weeks [COMBO I & II] or 150 mg every 2 weeks [LONG TERM]) or control (placebo [COMBO I and LONG TERM] or ezetimibe [COMBO II]). RESULTS: At baseline, LDL-C levels were similar across treatment groups; median lipoprotein(a) levels were higher in AA/B (33.0-120.0 mg/dL) vs W (7.1-66.3 mg/dL) and lower in H/L (5.0-38.3 mg/dL) vs non-H/L (7.7-69.0 mg/dL). At week 24, alirocumab significantly reduced LDL-C vs control. Alirocumab also reduced lipoprotein(a) compared with control across the subgroups. Treatment-emergent adverse events were similar between alirocumab (68.9-85.0%) and control (70.6-82.4%) regardless of race and ethnicity. CONCLUSION: Alirocumab significantly reduced LDL-C and Lp(a) levels compared with control, regardless of race and ethnicity, with overall safety comparable to control across most of the racial and ethnic groups analyzed.

Incidence of New Choroidal Neovascularization in Fellow Eyes of Patients With Age-Related Macular Degeneration Treated With Intravitreal Aflibercept or Ranibizumab.

IMPORTANCE: Incidence of conversion to neovascular age-related macular degeneration (nAMD) in untreated fellow eyes of patients who are treated for nAMD in 1 eye with anti-vascular endothelial growth factor agents provides important prognostic information to clinically manage patients. OBJECTIVE: To investigate the association of treatment assignment (intravitreal aflibercept vs ranibizumab) and baseline characteristics with fellow eye conversion to nAMD in the VEGF (Vascular Endothelial Growth Factor) Trap-Eye: Investigation of Efficacy and Safety in Wet AMD (VIEW) studies. DESIGN, SETTING, AND PARTICIPANTS: This post hoc analysis of the VIEW 1 and VIEW 2 studies (randomized, double-masked, active-controlled, multicenter, 96-week, phase 3 trials comparing the efficacy and safety of intravitreal aflibercept in 2457 patients with treatment-naive eyes with nAMD) analyzed a subgroup of participants treated for nAMD in 1 eye who had untreated fellow eyes without neovascularization at baseline. All participants in the VIEW studies were included in 1 of 4 groups: ranibizumab, 0.5 mg, every 4 weeks; aflibercept, 2 mg, every 4 weeks; aflibercept, 0.5 mg, every 4 weeks; or aflibercept, 2 mg, every 8 weeks after 3 injections at 4-week intervals. Data collection in the VIEW studies occurred from July 2007 to August 2011; the data analysis presented in this report took place from April 2016 to November 2018. INTERVENTIONS: Patients received no treatment in the fellow eyes unless after conversion to nAMD, when any treatment approved by heath authorities was given per the investigators' discretion. MAIN OUTCOMES AND MEASURES: Incidence of conversion to nAMD in patients with untreated fellow eyes that had not had clinical signs of neovascularization at baseline. RESULTS: A total of 1561 participants were included in this analysis. At 96 weeks, 375 patients (24.0%) experienced cases of conversion to neovascular disease in the fellow eye, including 107 of the 399 individuals who received ranibizumab, 0.5 mg, every 4 weeks; 93 of the 387 individuals who received aflibercept, 2 mg, every 4 weeks; 84 of the 387 individuals who received aflibercept, 0.5 mg, every 4 weeks; and 91 of the 388 individuals who received aflibercept, 2 mg, every 8 weeks after 3 doses at 4-week intervals. The rates were 18.1, 16.2, 14.7, and 16.0 per 100 patient-years at risk at week 96, respectively. On multivariate analysis, fellow eye conversion was associated with increasing patient age (per 10 years) at baseline (hazard ratio [HR], 1.20 [95% CI, 1.05-1.36]), female sex (HR, 1.32 [95% CI, 1.06-1.63]), intraretinal fluid in the study eye at baseline (HR, 1.28 [95% CI, 1.02-1.61]), and increasing choroidal neovascularization lesion size (per 10 mm2) in the study eye at baseline (HR, 1.29 [95% CI, 1.06-1.57]). Rates of fellow eye conversion were similar with either of the treatments. CONCLUSIONS AND RELEVANCE: In this secondary analysis of randomized clinical trial data, patients with active nAMD in 1 eye appeared to have a high risk for fellow eye conversion. Such patients should be monitored closely.

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.

Efficacy and Safety of Alirocumab 300 mg Every 4 Weeks in Individuals With Type 2 Diabetes on Maximally Tolerated Statin.

CONTEXT: In the ODYSSEY CHOICE I trial, alirocumab 300 mg every 4 weeks (Q4W) was assessed in patients with hypercholesterolemia. Alirocumab efficacy and safety were evaluated in a patient subgroup with type 2 diabetes mellitus (T2DM) and who were receiving maximally tolerated statins with or without other lipid-lowering therapies. METHODS: Participants received either alirocumab 300 mg Q4W (n = 458, including 96 with T2DM) or placebo (n = 230, including 50 with T2DM) for 48 weeks, with alirocumab dose adjustment to 150 mg every 2 weeks at Week (W) 12 if W8 low-density lipoprotein cholesterol (LDL-C) levels were ≥70 mg/dL or ≥ 100 mg/dL, depending on cardiovascular risk, or if LDL-C reduction was <30% from baseline. Efficacy end points included percentage change from baseline to W24 for lipids, and time-averaged LDL-C over W21 to W24. RESULTS: In individuals with T2DM, LDL-C reductions from baseline to W24 and the average of W21 to W24 were significantly greater with alirocumab (-61.6% and -68.8%, respectively) vs placebo. At W24, alirocumab significantly reduced levels of non-high-density lipoprotein cholesterol (HDL-C) and other lipids. At W24, 85.9% and 12.5% of individuals in the alirocumab and placebo groups, respectively, reached both non-HDL-C <100 mg/dL and LDL-C <70 mg/dL. At W12, In total, 18% of alirocumab-treated participants received dose adjustment. The most common treatment-emergent adverse events were upper respiratory tract infection and injection-site reaction. No clinically significant changes in fasting plasma glucose and glycated hemoglobin were observed. CONCLUSION: In individuals with T2DM, alirocumab 300 mg Q4W was generally well tolerated and efficacious in reducing atherogenic lipoproteins.

Efficacy and safety of alirocumab in patients with or without prior coronary revascularization: Pooled analysis of eight ODYSSEY phase 3 trials.

BACKGROUND AND AIMS: Patients with atherosclerotic cardiovascular disease (ASCVD) and prior revascularization are at high risk of further cardiovascular events and may require additional lipid-lowering therapies beyond maximally tolerated statin therapy. We assessed the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, in patients with ASCVD, with or without prior coronary revascularization (percutaneous coronary intervention [PCI] or coronary artery bypass graft [CABG]). METHODS: Data from eight controlled (placebo/ezetimibe) phase 3 ODYSSEY trials were pooled and stratified by trial design: alirocumab 150 mg or 75 mg with possible dose increase to 150 mg (75/150 mg) every 2 weeks (Q2W) versus placebo, and alirocumab 75/150 mg Q2W versus ezetimibe. Most patients received background maximally tolerated statin therapy. RESULTS: Among 4629 randomized patients with hypercholesterolemia, 3382 had ASCVD including 2191 with prior revascularization. Although baseline characteristics were comparable between alirocumab and control groups, revascularized patients were more likely to be male, have had prior myocardial infarction/stroke, have higher lipoprotein (a) and PCSK9 levels, and were more often treated with high-intensity statin therapy. Alirocumab significantly reduced low-density lipoprotein cholesterol (LDL-C; primary endpoint; p < 0.0001), lipoprotein (a), non-high-density lipoprotein cholesterol, and apolipoprotein B levels from baseline to week 24 (vs. control), regardless of stratified treatment group or revascularization status. On-treatment LDL-C levels with alirocumab ranged from 45.6 to 64.8 mg/dL. Alirocumab had a similar safety profile regardless of revascularization status, and higher rates of injection-site reactions versus controls. CONCLUSIONS: Alirocumab is generally well-tolerated and effective with a similar safety profile in high-risk patients with or without prior revascularization (PCI/CABG).

Efficacy and safety of alirocumab in individuals with type 2 diabetes mellitus with or without mixed dyslipidaemia: Analysis of the ODYSSEY LONG TERM trial.

BACKGROUND AND AIMS: Alirocumab, a monoclonal antibody to proprotein convertase subtilisin/kexin type 9, significantly reduces low-density lipoprotein cholesterol (LDL-C). We evaluated the efficacy and safety of alirocumab in individuals with type 2 diabetes mellitus (T2DM) with versus without mixed dyslipidaemia (MDL, defined as baseline LDL-C ≥70 mg/dL [1.8 mmol/L] and triglycerides ≥150 mg/dL [1.7 mmol/L]). METHODS: Data from 812 individuals with T2DM, from the placebo-controlled, 78-week, Phase 3 ODYSSEY LONG TERM trial of alirocumab 150 mg every 2 weeks (Q2W), on a background of maximally tolerated statins ±â€¯other lipid-lowering therapies, were pooled according to MDL status. Efficacy endpoints included percentage change from baseline to Week 24 in calculated LDL-C and other lipids/lipoproteins. RESULTS: In individuals with T2DM who received alirocumab 150 mg Q2W, mean LDL-C changes from baseline to Week 24 were -62.6% (vs. -6.0% with placebo) in those with MDL and -56.1% (vs. 5.6%) in those without MDL, with no significant between-group difference (p-interaction = 0.0842). Risk-based LDL-C goals (<70 [1.8 mmol/L] or <100 mg/dL [2.6 mmol/L]) were achieved by 69.1% and 72.4% of alirocumab-treated individuals with and without MDL, respectively. Mean reductions in non-high-density lipoprotein cholesterol (49.2% and 47.8%) and apolipoprotein B (50.2% and 49.1%) with alirocumab were also similar in those with and without MDL, respectively. Treatment-emergent adverse event rates were comparable between alirocumab-treated individuals with T2DM, with and without MDL. CONCLUSIONS: Reductions in LDL-C and other lipids with alirocumab, as well as safety and tolerability, were comparable between individuals with T2DM and with versus without MDL.

Impact of Baseline Characteristics on Treatment Response to Intravitreal Aflibercept Injection for Wet Age-Related Macular Degeneration.

PURPOSE: To determine whether wet age-related macular degeneration (AMD) treatment outcomes within prespecified patient subgroups were consistent with overall study results. Additionally, this subanalysis investigated whether there were any relationships between baseline characteristics and evaluated treatment outcomes. DESIGN: Post hoc subanalysis of The VEGF Trap-Eye: Investigation of Efficacy and Safety in Wet AMD (VIEW) 1 and 2, 2 similarly designed prospective, multicenter, double-masked, active-controlled, parallel-group, randomized clinical trials. PARTICIPANTS: Two thousand four hundred twelve patients with an active subfoveal choroidal neovascularization (CNV) lesion of any subtype secondary to AMD. METHODS: Primary and key secondary visual end points at week 52 were examined to explore the consistency of effect among prespecified subgroups of 5 baseline characteristics: age, best-corrected visual acuity (BCVA), lesion type, lesion size, and central retinal thickness (CRT). Additionally, within-group analyses were conducted to determine whether the mean changes in BCVA and CRT at 52 weeks were associated positively or negatively with the baseline characteristics of interest. MAIN OUTCOME MEASURES: Consistency of treatment outcomes among prespecified subgroups of baseline characteristics. RESULTS: For each baseline characteristic, tests for interaction within each prespecified subgroup and among the subgroups were not significant, suggesting that relative visual outcomes for each treatment arm were consistent with overall study outcomes. Within-group analysis revealed a significant association between baseline age, BCVA, and lesion size with BCVA outcomes at 52 weeks; namely, older age, greater BCVA, and larger lesion size were associated with lower mean BCVA gains at 52 weeks. CONCLUSIONS: Patients in all subgroups of baseline age, BCVA, lesion type, lesion size, and CRT experienced visual outcomes consistent with those of the overall study population. Additionally, baseline older age, better BCVA, and larger CNV lesion size were found to be associated independently with lower mean BCVA gains after 52 weeks of anti-vascular endothelial growth factor therapy. The influence of baseline age, BCVA, and CNV lesion size on treatment outcomes is consistent with other reports from large, prospective trials in wet AMD.
