Phase 1 Study of VEGF Trap in Patients With Diabetic Macular Edema

An Exploratory Study of the Safety, Tolerability and Biological Effect of a Single Intravitreal Administration of VEGF Trap in Patients With Diabetic Macular Edema

To assess the ocular and systemic safety and tolerability of a single intravitreal injection of VEGF Trap in patients with diabetic macular edema.

Study Overview

• Status: Completed
• Conditions: Diabetic Macular Edema
• Intervention / Treatment: Drug: VEGF Trap-Eye

Detailed Description

This is an open label study. Initially, 5 patients with DME will receive an ITV injection of VEGF Trap into the study eye. Additional patients may be enrolled at the same or additional dose levels. Patients will be observed for six weeks following the injection for assessments of ocular and systemic safety.

• Study Type: Interventional
• Enrollment (Actual): 5
• Phase: Phase 1

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (ADULT, OLDER_ADULT)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Diagnosis of diabetes mellitus (type 1 or type 2).
• Best corrected E-ETDRS visual acuity score of ≥ 24 letters (i.e., 20/320 or better) and ≤ 73 letters (i.e., 20/40 or worse).
• On clinical exam, definite retinal thickening due to diabetic macular edema involving the center of the macula.
• Retinal Thickness at the center point ≥ 250 microns.
• Media clarity, pupillary dilation, and patient cooperation sufficient for adequate fundus photographs.

Exclusion Criteria:

• History of any vitreous hemorrhage within 4 weeks prior to Visit 2 (Day 1).
• Macular edema due to causes other than diabetic macular edema. An eye should be considered ineligible: (1) if the macular edema is considered to be related to cataract extraction or (2) clinical exam and/or OCT suggests that vitreoretinal interface disease (e.g., a taut posterior hyaloid or epiretinal membrane) is the primary cause of the macular edema.
• An ocular condition is present such that, in the opinion of the investigator, visual acuity would not improve from resolution of macular edema (e.g., foveal atrophy, pigmentary changes, dense subfoveal hard exudates, nonretinal condition).
• An ocular condition is present (other than diabetes) that, in the opinion of the investigator, might affect macular edema or alter visual acuity during the course of the study (e.g., vein occlusion, age-related macular degeneration, uveitis or other ocular inflammatory disease, neovascular glaucoma, Irvine-Gass Syndrome, etc.).
• Presence of any other condition or laboratory abnormality, which, in the opinion of the Investigator, would interfere with the assessment of disease status/progression or jeopardize the patient's appropriate participation in this Phase 1 study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
To assess the ocular and systemic safety and tolerability of a single intravitreal (IVT) injection of VEGF Trap-Eye in patients with diabetic macular edema (DME)	Assessments for safety and tolerablity are performed at each visit (Visit 1 - Visit 10)

Secondary Outcome Measures

Outcome Measure	Time Frame
To obtain a preliminary assessment of the effect of a single dose of VEGF Trap-Eye on central retinal thickness (CRT) at the center point as determined by optical coherence tomography (OCT)	Assessments for CRT are performed at each visit (Visit 1 - Visit 10) by means of OCT.
To obtain a preliminary assessment of the effect of a single IVT administration of VEGF Trap-Eye on visual acuity	Assessments for visual acuity are performed at each visit (Visit 1 - Visit 10).
