DUBLIN, Nov. 13, 2015 /PRNewswire/ -- Allergan plc (NYSE: AGN), a leading global pharmaceutical company announced today that a post-hoc analysis of best corrected visual acuity (BCVA) data in diabetic macular edema (DME) patients treated with anti-vascular endothelial growth factor (anti-VEGF) therapy suggests that long-term response in anti-VEGF treatment of DME can be assessed after three injections.i This analysis, “Early Anti-VEGF Response and Long-term efficacY (EARLY Analysis),” is based on the Protocol I study, which was a three-year Phase III multicenter trial including 691 patients (854 study eyes) with DME conducted by the Diabetic Retinopathy Clinical Research Network (DRCR.net).I

The DRCR.net is a collaborative effort sponsored by the National Eye Institute of the National Institutes of Health (U.S. Department of Health and Human Services) for facilitating clinical research of diabetic retinopathy, macular edema and associated retinal conditions.ii Allergan conducted this post-hoc analysis to support patient care in the management of DME.
“The EARLY Analysis study has relevance for retinal physicians looking to assess how patients will respond to anti-VEGF treatment long-term,” said Pravin Dugel, M.D., Clinical Professor, USC Eye Institute, Keck School of Medicine, University of Southern California and Managing Partner of Retinal Consultants of Arizona. “This data suggests that if treatment goals are not achieved after three injections, further expected improvement may be minimal and physicians may want to consider other treatment strategies.”i
This analysis of Protocol I looked at one anti-VEGF that is FDA-approved for the treatment of DME and assessed outcomes in three cohorts based on observed BCVA response, which was defined by letters gained on the Early Treatment of Diabetic Retinopathy Study (ETDRS) chart at week 12.i The cohorts were defined as a gain of less than five letters, a gain between five and nine letters and a gain of greater than or equal to 10 letters.i The unadjusted differences in mean BCVA change from baseline was +0.3, +6.9 and +15.2 at 12 weeks, respectively, and +3.0, +8.2 and +13.8 at three years, respectively.i After multivariate adjustment, significant correlation remained between BCVA gain at week 12 and years one and three (p <0.001).i
“DME is difficult to manage and it requires a customized patient approach,” said David Nicholson, Ph.D., Executive Vice President, Global Brands R&D, Allergan. “The EARLY Analysis underscores Allergan’s commitment to broadening our knowledge of the current landscape of DME treatment patterns.”
While additional analysis is needed to confirm these findings, the EARLY Analysis shares information that may help shape treatment patterns for patients with DME.
About Diabetic Macular Edema
DME is a growing public health problem due to the increasing prevalence of diabetes.iii According to the U.S. Centers for Disease Control and Prevention, as of 2014, 29.1 million people 9.3 percent of the U.S. population have diabetes; 1.7 million new cases of diabetes were diagnosed in people aged 20 years or older in 2012.iv A high level of health care utilization is not surprising given the overall health status of this population.v
