Age-related Macular Degeneration, Choroidal Neovascularization
Conditions
Brief summary
The purpose of this study is to evaluate the safety, biological activity and pharmacodynamic effect of repeated intravitreal doses of hI-con1 0.3 mg administered as monotherapy and in combination with ranibizumab 0.5 mg compared to ranibizumab 0.5 mg monotherapy in treating patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD).
Interventions
Intravitreal injection of hI-con1 0.3 mg
Intravitreal injection of ranibizumab 0.5 mg
No injection is given, a needleless syringe is used to mimic an injection.

Eligibility
Inclusion criteria
* Males or females of any race at least 50 years of age * Active primary Choroidal Neovascularization (CNV) secondary to Age-Related Macular Degeneration (AMD) in the study eye * Best Corrected Visual Acuity (BCVA) of 70 to 24 letters (worse than 20/40 up to 20/320) in the study eye

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Best Corrected Visual Acuity (BCVA) in the Study Eye at Month 3 | Baseline and Month 3 | Best corrected visual acuity (BCVA) was measured pre treatment prior to dilating eyes, using standard Early Treatment Diabetic Retinopathy Study (ETDRS) retro illuminated charts. The BCVA was recorded as the total letter score in each eye. |
| Change From Baseline in Central Retinal Subfield Thickness (CST) in the Study Eye at Month 3 | Baseline and Month 3 | Optical Coherence Tomography (OCT) imaging was performed pre treatment during visits in which study treatment was administered and to assess lesion characteristics for the study eye. and were evaluated by a central reading center for standardized grading. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in BCVA in the Study Eye at Month 6 | Baseline and Month 6 | Best corrected visual acuity (BCVA) was measured pre treatment prior to dilating eyes, using standard Early Treatment Diabetic Retinopathy Study (ETDRS) retro illuminated charts. The BCVA was recorded as the total letter score in each eye. |
| Change From Baseline in CST in the Study Eye at Month 6 | Baseline and Month 6 | Central Retinal Subfield Thickness (CST) as measured by Optical Coherence Tomography (OCT). The change from the baseline measurement was compared to the month 6 measurement. |
