Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male or female aged 18 years or older
  • Type 1 or type 2 Diabetes Mellitus
  • Central-involved DME with central subfield thickness of ≥ 320µm on Spectralis® spectral domain optical coherence tomography (SD-OCT) or ≥ 305µm on non-Spectralis SD-OCT, in the study eye
  • Best-corrected visual acuity (BCVA) ≤ 62 and ≥ 23 ETDRS letter score in the study eye
  • Written informed consent obtained from the subject prior to screening procedures

Exclusion Criteria:

  • Macular edema due to causes other than DME
  • Concurrent disease in the study eye, other than central-involved DME, that could compromise BCVA, require medical or surgical intervention during the study period or could confound interpretation of the results
  • Any condition that could confound the ability to detect a change in central subfield thickness in the study eye
  • Previous confounding treatments / procedures, or expected to require confounding treatments / procedures at any time during the study period
  • Presence of neovascularization at the disc (NVD) in the study eye
  • Uncontrolled glaucoma in the study eye
  • Any active ocular / intra-ocular infection or inflammation in either eye
  • Poorly controlled Diabetes Mellitus
  • Uncontrolled hypertension

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Incidence of dose-limiting toxicities up to the Day 14 visit
Time Frame: From Day 0 up to Day 14
From Day 0 up to Day 14

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Incidence of systemic and ocular adverse events including serious adverse events up to the end of the study
Time Frame: From Day 0 up to Day 84
From Day 0 up to Day 84
Occurrence of laboratory abnormalities up to the end of the study
Time Frame: At Screening, Day 1, Day 7, Day 28 and Day 84
