研究概览

简要总结

Researchers are looking for new ways to treat diabetic macular edema (DME). In this trial, researchers want to learn if a trial medicine called MK-8748 can treat DME. An available standard (usual) treatment for DME is aflibercept. However, standard treatments such as aflibercept may not work for every person.

The main goal of this trial is to learn if MK-8748 works as well as aflibercept to treat DME.

入选标准

  • The main inclusion criteria include but are not limited to the following:
  • Has Type 1 or Type 2 diabetes mellitus and a hemoglobin A1c (HbA1c) of ≤12%
  • Has a decrease in vision in the study eye determined by the Investigator to be primarily the result of diabetic macular edema (DME)
  • For participants who are treatment-naïve for DME, the diagnosis must have been made within 9 months of screening. For all treatment-experienced participants, the first treatment should have been no longer than 3 years prior to the Screening visit

  • Has newly diagnosed or previously untreated diabetes mellitus and initiated oral or injectable anti-diabetic medication within 3 months to first dose of study intervention
  • Has history of cataract surgery and/or minimally invasive glaucoma surgery in the study eye within 90 days of screening
  • Has any treatment for complications of cataract surgery with steroids or yttrium aluminum garnet (YAG) laser capsulotomy in the study eye within 90 days of screening
  • Has advanced or uncontrolled glaucoma in the study eye
  • Has any history of retinal detachment or treatment or surgery for retinal detachment in the study eye

  • Has uncontrolled blood pressure at screening

研究组 & 干预措施

MK-8748 Low Dose

Experimental

Participants receive 5 initial administrations of MK-8748 low dose every 4 weeks (Q4W), then continue to receive MK-8748 low dose every 8 weeks (Q8W) until week 48. After week 48, participants will be treated at intervals determined based on individualized response to treatment, up to week 100.

干预措施: MK-8748 (Drug)

MK-8748 High Dose

Experimental

Participants receive 5 initial administrations of MK-8748 high dose every 4 weeks (Q4W), then continue to receive MK-8748 high dose every 8 weeks (Q8W) until week 48. After week 48, participants will be treated at intervals determined based on individualized response to treatment, up to week 100.

干预措施: MK-8748 (Drug)

Aflibercept 2 mg

Active Comparator

Participants receive 5 initial administrations of aflibercept 2 mg every 4 weeks (Q4W), then continue to receive aflibercept 2mg every 8 weeks (Q8W) until week 100.

结局指标

主要结局

Mean Change in Best-Corrected Visual Acuity (BCVA) (Early Treatment of Diabetic Retinopathy Study [ETDRS] Letters) From Baseline to Year 1

时间窗: Baseline and 1 Year

Participants' BCVA in the study eye will be measured using the Early Treatment of Diabetic Retinopathy (ETDRS) methodology. The ETDRS letter score ranges from 0 to 100, with a higher score indicating better visual acuity. Mean change in ETDRS letters from baseline to Year 1 will be assessed.
