EFFICACY AND SAFETY OUTCOMES OF INTRAVITREAL AFLIBERCEPT FOCUSING ON PATIENTS WITH DIABETIC MACULAR EDEMA FROM JAPAN.

ABSTRACT: PURPOSE:To evaluate the efficacy and safety of intravitreal aflibercept injection (IAI) in Japanese patients with diabetic macular edema (DME). METHODS:VIVID-DME was a Phase 3 study comprising patients with DME randomized 1:1:1 to IAI 2 mg every 4 weeks (2q4), IAI 2 mg every 4 weeks until Week 16 then 8-week dosing (2q8), and laser. A total of 403 patients (76 Japanese) were included in this study. VIVID-Japan (72; all Japanese patients) was a nonrandomized, open-label study comprising Japanese patients with DME receiving IAI 2q4 until Week 16, then 2q8. Primary efficacy endpoint (Week 52) of VIVID-DME was mean change from baseline in best-corrected visual acuity; VIVID-Japan evaluated safety and tolerability. RESULTS:Mean change in best-corrected visual acuity (letters) for 2q4, 2q8, and laser groups was +10.6, +10.9, and +1.2 and +9.8, +9.5, and +1.1 in the non-Japanese and Japanese populations of VIVID-DME, respectively. In VIVID-Japan, it was +9.3 for IAI 2q8. Intravitreal aflibercept injection also provided consistently greater benefits for anatomical outcomes versus laser. Adverse events were consistent with the known safety profile of IAI. CONCLUSION:In Japanese patients with DME, IAI treatment was superior to laser for visual and anatomical outcomes and resulted in efficacy and safety outcomes similar to those in a non-Japanese patient population.

Project description:PurposeThe prevalence of diabetes and diabetes-related complications, including diabetic macular edema (DME), is increasing in Asia and worldwide.MethodsVIVID-East was a 12-month, double-masked, randomized, active-controlled, Phase 3 trial (NCT01783886) enrolling adult patients (aged ≥18 years) with DME at 25 centers across China, Hong Kong, Republic of Korea, and Russia. Eyes were randomized 1:1:1 to 2 mg intravitreal aflibercept (IVT-AFL) every 4 weeks (2q4; N=127), 2 mg IVT-AFL every 8 weeks (after 5 initial monthly doses from baseline to week 16) with sham injections on nontreatment visits (2q8; N=127), or macular laser photocoagulation at baseline and sham injections at every visit (laser control group; N=124). The primary efficacy endpoint was mean change in best corrected visual acuity (BCVA) from baseline to week 52.ResultsCompared with baseline, at week 52 the mean (SE) BCVA in the 2q4 and 2q8 groups gained +13.6 (0.9) and +13.1 (1.0) letters, respectively, versus -0.5 (1.4) letters in the laser group (P<0.0001 for both). A significantly higher proportion of patients treated with IVT-AFL (2q4 and 2q8) achieved a ≥10-letter or ≥15-letter gain compared with laser (both P<0.0001) (≥10-letter gain: 70.9%, 62.7%, and 23.4%, respectively; ≥15-letter gain: 43.3%, 36.5%, and 12.1%, respectively). Mean reduction in central retinal thickness from baseline to week 52 was significantly greater with IVT-AFL versus laser treatment. Incidence of treatment-emergent adverse events was low and similar across groups; conjunctival hemorrhage (11.8%), retinal hemorrhage (8.7%), retinal aneurysm (7.5%), and retinal exudates (5.5%) being the most frequently reported. Visual and anatomic outcomes in the Chinese subgroup were consistent with the overall population.ConclusionIVT-AFL treatment resulted in significant visual and anatomic improvements in Asian patients with DME. Treatment benefits observed in the overall study population were mirrored in the subgroup of Chinese patients, who made up the largest population group in the study.Study registrationNCT01783886.

Project description:BackgroundThe relative efficacy and safety of intravitreous aflibercept, bevacizumab, and ranibizumab in the treatment of diabetic macular edema are unknown.MethodsAt 89 clinical sites, we randomly assigned 660 adults (mean age, 61±10 years) with diabetic macular edema involving the macular center to receive intravitreous aflibercept at a dose of 2.0 mg (224 participants), bevacizumab at a dose of 1.25 mg (218 participants), or ranibizumab at a dose of 0.3 mg (218 participants). The study drugs were administered as often as every 4 weeks, according to a protocol-specified algorithm. The primary outcome was the mean change in visual acuity at 1 year.ResultsFrom baseline to 1 year, the mean visual-acuity letter score (range, 0 to 100, with higher scores indicating better visual acuity; a score of 85 is approximately 20/20) improved by 13.3 with aflibercept, by 9.7 with bevacizumab, and by 11.2 with ranibizumab. Although the improvement was greater with aflibercept than with the other two drugs (P<0.001 for aflibercept vs. bevacizumab and P=0.03 for aflibercept vs. ranibizumab), it was not clinically meaningful, because the difference was driven by the eyes with worse visual acuity at baseline (P<0.001 for interaction). When the initial visual-acuity letter score was 78 to 69 (equivalent to approximately 20/32 to 20/40) (51% of participants), the mean improvement was 8.0 with aflibercept, 7.5 with bevacizumab, and 8.3 with ranibizumab (P>0.50 for each pairwise comparison). When the initial letter score was less than 69 (approximately 20/50 or worse), the mean improvement was 18.9 with aflibercept, 11.8 with bevacizumab, and 14.2 with ranibizumab (P<0.001 for aflibercept vs. bevacizumab, P=0.003 for aflibercept vs. ranibizumab, and P=0.21 for ranibizumab vs. bevacizumab). There were no significant differences among the study groups in the rates of serious adverse events (P=0.40), hospitalization (P=0.51), death (P=0.72), or major cardiovascular events (P=0.56).ConclusionsIntravitreous aflibercept, bevacizumab, or ranibizumab improved vision in eyes with center-involved diabetic macular edema, but the relative effect depended on baseline visual acuity. When the initial visual-acuity loss was mild, there were no apparent differences, on average, among study groups. At worse levels of initial visual acuity, aflibercept was more effective at improving vision. (Funded by the National Institutes of Health; ClinicalTrials.gov number, NCT01627249.).
