Phase 4

Completed

• Conditions: Vitreomacular Traction; Vitreomacular Adhesion
• Interventions: Drug: Ocriplasmin

• Registration Number: NCT02035748
• Lead Sponsor: Alcon Research

Brief Summary

The purpose of this study is to observe the anatomical and functional outcomes of ocriplasmin (JETREA®) over a 6-month follow-up period.

Detailed Description

After receiving a single intravitreal injection as per country's product label (Day 0), subjects were followed for a 6-month period (Day 180).

Group	Intervention	Description
Ocriplasmin	Ocriplasmin	Ocriplasmin 0.125 mg in a 0.1 mL volume administered as a single dose by intravitreal injection

Primary Outcome Measures

Name	Time	Method
Proportion of Subjects With Nonsurgical Resolution of Focal Vitreomacular Traction (VMT/VMA) at Day 28, as Determined by Central Reading Center (CRC) Spectral Domain Optical Coherence Tomography (SD-OCT) Evaluation	Baseline, Day 28	Vitreous separation was assessed by SD-OCT using scores ranging from 1 (vitreous attached from macula to ON; separated elsewhere cannot determine foveal) to 12 (unable to determine state of separation). Nonsurgical resolution was defined as a change from baseline score of 5/6/8 to 7/9/10 at Day 28. The assessment of resolution of VMT/sVMA was based upon the anatomical resolution of VMA only, i.e. no resolution of the related symptoms was considered. Thus, the term VMA is used interchangeably with VMT/sVMA. Proportion of subjects is presented as a percentage, with percentage based on the number of subjects who have VMT/sVMA at baseline and SD-OCT value at Day 28. One eye (study eye) contributed to the analysis.

Secondary Outcome Measures

Name	Time	Method
Proportion of Subjects With Nonsurgical Closure of Macular Hole (MH), if Present at Baseline	Day 28, Day 90, Day 180	The closure of macular hole (a full thickness defect of the retinal tissue involving the anatomical fovea) is defined as a flattened and reattached hole rim along the whole circumference of macular hole. Closure was determined by SD-OCT evaluation and the percentage of subjects tabulated. Proportion of subjects is presented as a percentage, with percentage based on the number of subjects who had macular hole at baseline and OCT value at each specific visit. One eye (study eye) contributed to the analysis.
Proportion of Subjects With Nonsurgical Resolution of VMT/sVMA	Baseline, Day 90, Day 180	Vitreous separation was assessed by SD-OCT using scores ranging from 1 (vitreous attached from macula to ON; separated elsewhere cannot determine foveal) to 12 (unable to determine state of separation). Nonsurgical resolution was defined as a change from baseline score of 5/6/8 to 7/9/10 at Day 90 and Day 180. The assessment of resolution of VMT/sVMA was based upon the anatomical resolution of VMA only, i.e. no resolution of the related symptoms was considered. Thus, the term VMA is used interchangeably with VMT/sVMA. Proportion of subjects is presented as a percentage, with percentage based on the number of subjects who have VMT/sVMA at baseline and SD-OCT value at Day 90/Day 180. One eye (study eye) contributed to the analysis.
Proportion of Subjects Experiencing Pars Plana Vitrectomy (PPV) at Day 180	Day 180	Pars plana vitrectomy (the surgical removal of vitreous gel from the eye) was captured in Concomitant Ocular Procedures. Proportion of subjects is reported as a percentage. One eye (study eye) contributed to the analysis.
Mean Nonsurgical Change From Baseline in Central Foveal Thickness (CFT)	Baseline (Day 0), Day 28, Day 180	Nonsurgical change in central foveal thickness (CFT values after a vitrectomy were imputed with the last non-missing value prior to the vitrectomy) was determined by subtracting the measurements in subretinal fluid and retinal pigment epithelium (RPE) elevations and/or SHRM (subretinal hyper-reflective material, such as choroidal neovascularization (CNV)) from the value in total retinal measurement. A lower CFT indicates improvement. One eye (study eye) contributed to the analysis.
Nonsurgical Change From Baseline in Best-corrected Visual Acuity (BCVA) at Distance	Baseline (Day 0), Day 28, Day 90, Day 180	BCVA (with spectacles or other visual corrective devices) was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) testing at 4 meters. The charts contain 14 rows of letters. BCVA was calculated as the number of letters read correctly and improvement defined as an increase (gain) in letters read from the baseline assessment. One eye (study eye) contributed to the analysis.
