Ranibizumab in Hemorrhagic Choroidal Neovascularization Trial
This research is being done to look at the effects of an experimental drug, ranibizumab, on a condition called "predominantly hemorrhagic subfoveal choroidal neovascularization (CNV)" due to wet age-related macular degeneration.
A predominantly hemorrhagic CNV lesion is diagnosed when at least 50% of the choroidal neovascular lesion is occupied by blood under the retina. We want to find out if injections of ranibizumab into the eye will help patients with this condition.

描述
Inclusion Criteria:
Subjects will be eligible if the following criteria are met:
- Ability to provide written informed consent and comply with study assessments for the full duration of the study.
- Predominantly hemorrhagic subfoveal CNV (at least 50% of the lesion composed of hemorrhage) from age-related macular degeneration (AMD) resulting in visual acuity of 20/40 or worse.
- Age greater than 50 years.
- Participant must have media clear enough to permit fundus photography, fluorescein angiography, and optical coherence tomography.
Exclusion Criteria:
Subjects who meet any of the following criteria will be excluded from this study:
- Known hypersensitivity to humanized monoclonal antibodies
- History (within past 6 months) or evidence of severe cardiac disease (apparent in electrocardiogram abnormalities, clinical history of unstable angina, acute coronary syndrome, myocardial infarction, revascularization procedure within 6 months prior to baseline, atrial or ventricular tachyarrhythmias requiring ongoing treatment).
- History of stroke within 6 months of study entry.
- Current acute ocular or periocular infection.
- Any major surgical procedure within one month of study entry.
- Known serious allergies to fluorescein dye.
- Previous participation in a clinical trial (for either eye) involving anti-angiogenic drugs (pegaptanib, ranibizumab, anecortave acetate, Protein Kinase C inhibitors, etc) within last 6 months.
- Previous intravitreal drug delivery (e.g., intravitreal corticosteroid injection or device implantation) in the study eye within the last 6 months.
- History of subfoveal laser treatment in the study eye.
- History of other visually-limiting conditions such as optic neuropathy, amblyopia, choroidal neovascularization due to causes other than AMD in the study eye.
- Ocular inflammation (including trace or above) in the study eye.
- Inability to comply with study or follow up procedures.

Number of Subjects Avoiding 15 or More Letter Loss of Best Corrected Visual Acuity From Baseline to 12 Months on an Early Treatment Diabetic Retinopathy Study (ETDRS) Visual Acuity Chart Measured at 4 Meters.
大体时间:12 months
|
Visual acuity measured prior to first treatment with ranibizumab and at 12 months following the first treatment were compared for each subject enrolled in the study.
The 12 month follow-up visual acuity was subtracted from the baseline visual acuity.
Avoiding a 15 or more letter loss in visual acuity was considered a successful outcome.

Potential complications included:
Subjects were monitored for potential drug-related ocular adverse effects: intraocular inflammation (uveitis), endophthalmitis, central retinal vein occlusion, transient elevation of IOP, acute reduction in the visual acuity, vitreous hemorrhage, injection-site pain, retinal hemorrhage, posterior vitreous detachment, and subconjunctival hemorrhage. Subjects were monitored for potential adverse effects of intravitreal injections: crystalline lens penetration, retinal break and/or detachment, vitreous hemorrhage, inflammation, and infection. Potential systemic adverse effects were captured by monitoring vital functions such as cardiovascular function, nervous system function, renal function, and gastrointestinal function. |
