LHA510 Proof-of-Concept Study as a Maintenance Therapy for Patients With Wet Age-Related Macular Degeneration

Alcon, a Novartis Company136 enrolled

Overview

The purpose of this study is to evaluate the efficacy of 84 successive days of topically administered LHA510 compared to vehicle in reducing the number of patients requiring intravitreal (IVT) anti-vascular endothelial growth factor (VEGF) therapy (Lucentis®) for recurrence of active choroidal neovascularization (CNV).

On Day -1, patients will receive an IVT Lucentis® injection in the study eye, and then will be randomized to receive either topical LHA510 ophthalmic suspension or vehicle in a 1:1 ratio for 84 days. Patients with recurrence of active CNV in the study eye during the study will receive rescue IVT Lucentis® injections. Following the treatment period, subjects will return for a follow-up visit and a disposition visit. Only one eye (designated as the study eye) will be dosed with either topical LHA510 or vehicle per patient.

Outcomes

Primary Outcomes

Number of Subjects With Positive LUCENTIS® Retreatment Status at Day 84

For subjects who completed the Day 84 visit, retreatment need status was positive if LUCENTIS® retreatment (injection) was required before or at Day 84, including requiring retreatment at or before the Day 84 visit with the actual retreatment performed at a later visit.

Time frame: Day 84

Secondary Outcomes

Time to First LUCENTIS® Retreatment Need Identification up to Day 84

The time was determined based on the visit of the treatment period when a patient was identified as requiring retreatment with LUCENTIS.

Time frame: Day 14, Day 28, Day 56, Day 84

Number of LUCENTIS® Retreatment Needs Identified Required up to Day 84

The number of LUCENTIS retreatment needs identified before or at the Day 84 visit (even if retreatment was applied at a later visit) for each patient was used in the analysis

Time frame: Up to Day 84

Number of Subjects Requiring LUCENTIS® Retreatment at Days 28 and 56

The number of LUCENTIS® retreatment needs identified before or at the Day 28 and Day 56 visits (even if retreatment was applied at a later visit) for each subject was used in the analysis.

Time frame: Day 28, Day 56

Change From Randomization Visit (Day -1) in Central Subfield Thickness Total (CSFTtot) at All Visits at the Study Site

The thickness of the retina was measured using SD-OCT and reported as a difference, in micrometers, between a given post-Randomization Visit and Randomization Visit (Day-1). A negative number indicates a reduction in thickness, whereas a positive number indicates an increase. An increase in thickness may indicate a progression of the underlying disease. Only one eye (study eye) contributed to the analysis.

Time frame: Day -1, Day 14, Day 28, Day 56, Day 84

Change From Randomization Visit (Day -1) in Best Corrected Visual Acuity (BCVA) at All Visits at the Study Site

Measurement of best corrected (with spectacles or other visual corrective devices) visual acuity was conducted in each eye individually using ETDRS charts and reported in number of letters read correctly. An increase (gain) in letters read from the baseline assessment indicates improvement. Only one eye (study eye) contributed to the analysis.

Time frame: Day -1, Day 14, Day 28, Day 56, Day 84

Change From Randomization Visit (Day -1) in Central Subfield Thickness, Neuro-retina (CSFTnr) by Visit

The thickness of the neuro-retina, at the level of the central subfield, was measured using SD-OCT and reported as a difference, in micrometers, between a given post-Randomization Visit and Randomization Visit (Day-1). A negative number indicates a reduction in thickness, whereas a positive number indicates an increase. An increase in thickness may indicate a progression of the underlying disease. Only one eye (study eye) contributed to the analysis.

Time frame: Day -1, Day 28, Day 84

Change From Randomization Visit (Day -1) in Lesion Thickness by Visit

The thickness of the neovascular lesion was measured using SD-OCT and reported as a difference, in micrometers, between a given post-Randomization Visit and Randomization Visit (Day-1). A negative number indicates a reduction in thickness, whereas a positive number indicates an increase. An increase in thickness of the neovascular lesion may indicate a progression of the underlying disease. Only one eye (study eye) contributed to the analysis.

Time frame: Day -1, Day 28, Day 84

Change From Randomization Visit (Day -1) in Subretinal Fluid - Foveal Involvement (SRFfi) Thickness by Visit

The thickness of subretinal fluid involving the fovea was measured using SD-OCT and reported as a difference, in micrometers, between a given post-Randomization Visit and Randomization Visit (Day-1). A negative number indicates a reduction in thickness, whereas a positive number indicates an increase. An increase in thickness of subretinal fluid involving the fovea may indicate a progression of the underlying disease. Only one eye (study eye) contributed to the analysis.

Time frame: Day -1, Day 28, Day 84

Change From Randomization Visit (Day -1) in Pigment Epithelial Detachment - Foveal Involvement (PEDfi) Thickness by Visit

The thickness of pigment epithelial detachment involving the fovea was measured using SD-OCT and reported as a difference, in micrometers, between a given post-Randomization Visit and Randomization Visit (Day-1). A negative number indicates a reduction in thickness, whereas a positive number indicates an increase. An increase in thickness of pigment epithelial detachment involving the fovea may indicate a progression of the underlying disease. Only one eye (study eye) contributed to the analysis.

Time frame: Day -1, Day 28, Day 84

Change From Randomization Visit (Day -1) in Total Lesion Size by Visit

The total wet AMD lesion size was measured using FA and reported as a difference, in millimeter squared, between a given post-Randomization Visit and Randomization Visit (Day-1). A negative number indicates a reduction, whereas a positive number indicates an increase. An increase in wet AMD lesion size may indicate a progression of the underlying disease. Only one eye (study eye) contributed to the analysis.

Time frame: Day -1, Day 84

Change From Randomization Visit (Day -1) in CNV Size by Visit

The size of CNV (area of new blood vessels in the choroid layer of the retina) was measured using FA and reported as a difference, in millimeter squared, between a given post-Randomization Visit and Randomization Visit (Day-1). A negative number indicates a reduction, whereas a positive number indicates an increase. An increase in CNV size may indicate a progression of the underlying disease. Only one eye (study eye) contributed to the analysis.

Time frame: Day -1, Day 84

Plasma Concentration of LHA510 and CRA398

Samples collected from subjects, after multiple topical ocular dosing of LHA510, were analyzed to determine concentrations of LHA510 and its metabolite, CRA398. Plasma LHA510 and CRA398 concentrations were quantitated by a validated liquid chromatography-tandem mass spectroscopy assay method. Below the limit of quantification (BLQ) is treated as zero.
