An Open-label, Dose Escalating Study to Assess the Safety and Tolerability of a Single Administration of FOV2302 (Ecallantide) in Patients With Macular Edema Associated With Central Retinal Vein Occlusion

The purpose of the study is to evaluate the safety and tolerability of a single administration of FOV2302 (ecallantide) in patients with macular edema associated with central retinal vein occlusion.

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.

Detailed Description

Occlusive retinal vascular disease is not uncommon. Central retinal vein occlusion (CRVO) is the second most common vision-impairing vascular disorder of the retina following diabetic retinopathy. Severe visual loss from CRVO is caused by a combination of retinal edema and neovascular proliferation and ischemia. Vascular endothelial factors as they stimulate angiogenesis and increase vascular permeability, are majors pathogenic factors in CRVO. Counteracting these neovascular effects provide significant therapeutic benefit to subjects suffering from this disorder. Macular edema in this condition results from a conjunction of several, as yet, partially unknown factors.

Macular edema may occur in diseases causing cumulative injury over many years, such as diabetic retinopathy, or as a result of more acute events, such as branch retinal vein occlusion (BRVO) or central retinal vein occlusion (CRVO).

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:

  • Recent onset (< 6 months), non-ischemic CRVO (defined as association of documented retinal hemorrhage in all 4 quadrants of the retina with dilated veins) in patients who have not received treatment for their condition (e.g., no periocular depot or intraocular treatment [including corticosteroid and anti-VEGF], systemic corticosteroids or laser nor hemodilution).
  • Retinal thickness measured by Stratus OCT > 250µm in the central subfield of study eye at baseline.
  • BCVA score (measured by the ETDRS chart between 5 letters (20/800 Snellen equivalent) and 65 letters (20/50) in the study eye at baseline.
  • Media clarity, pupillary dilation and participant cooperation sufficient for adequate fundus photographs.
  • Females of childbearing potential using adequate birth control at Day 0 until study completion.
  • Patient able (in the opinion of the investigator) and willing to return for all scheduled visits and assessments.
  • Ability to read, understand and willingness to provide informed consent.

Exclusion Criteria:

  • Rubeosis iridis or neovascular glaucoma at baseline.
  • Preretinal neovascularisation at baseline.
  • Ischemic CRVO, defined by more than 10 disc area of non-perfusion on fluorescein angiography at baseline.
  • Any grade of diabetic retinopathy.
  • Other eye condition that could contribute to macular edema or cause retinal vascular changes (including vitreomacular traction, uveitis and inflammatory disease, etc).
  • Patients who have received treatment for their condition (e.g., no periocular depot or intraocular treatment [including corticosteroid and anti-VEGF], systemic corticosteroids or laser nor hemodilution).
  • Ocular surgery (including cataract extraction, scleral buckle, etc.) and/or YAG capsulotomy within 3 months preceding treatment date or anticipated within the 3 months following treatment administration.
  • Poorly controlled ocular hypertension and/or glaucoma (IOP greater than 25 mmHg despite maximal therapy).
  • History of pars plana vitrectomy.
  • Aphakia or anterior chamber intraocular lens.
  • Presence of visible sclera thinning or ectasia.
  • Presence of substantial cataract or other media opacity that, in the opinion of the investigator, is likely to interfere with visualization of the fundus or completion of study measurements.
  • Any active ocular or peri-ocular infection (including conjunctivitis, chalazion or significant blepharitis).

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
Safety and tolerability parameters to determine MTD: 1. Systemic parameters: adverse events (AEs), coagulation parameters (APTT, ACT) 2. Ophthalmologic parameters: BCVA, OCT, ocular inflammation, IOP
Time Frame: 3 months post-dose
3 months post-dose

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
Assess the pharmacodynamics up to five dose levels of a single administration of FOV2302 (ecallantide) by longitudinal measurements of the percent change of the macula thickness versus baseline as measured by OCT
Time Frame: 3 months post-dose
3 months post-dose
