A Study of the Safety and Tolerability of Intravitreal LKA651 in Patients With Diabetic Macular Edema

Diabetic Macular Edema Clinical Trial

Official title: A Randomized, Sham Controlled, Single Ascending Dose Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamic Activity of Intravitreal LKA651 in Patients With Diabetic Macular Edema

Status Withdrawn

Clinical Trial Summary

The purpose of this study is to evaluate the initial safety of intravitreal (IVT) LKA651 and potential for use alone or in combination with Ranibizumab ophthalmic solution (Lucentis®) for the treatment of Diabetic Macular Edema (DME) in patients with symptomatic disease.

Clinical Trial Description

This first-in-human study will be conducted in 2 parts. Part 1 is an ascending dose design to assess the safety, tolerability, pharmacodynamics and pharmacokinetics of various single IVT doses of LKA651 in up to 48 subjects with diabetic macular edema. Subjects will be randomized to receive active or sham injections in a 3:1 ratio. A total of 6 cohorts (8 subjects per cohort) may be enrolled in Part 1. Each subject will participate in a screening/eligibility period (up to 60 days), a treatment period (single day), and an 84 day follow up period. A total of up to 11 visits will take place, all on an out-patient basis. An independent data monitoring committee (DMC) will be chartered to review cumulative safety data and approve each dose escalation and cohort progression in this first-in-human trial.

Part 2 is a double-masked design to assess the safety/tolerability, pharmacokinetics and pharmacodynamics of a single IVT dose of LKA651 when co-administered with Lucentis®. A total of up to 3 cohorts (8 subjects per cohort) may be enrolled in Part 2. Each subject will participate in a screening/eligibility period (up to 60 days), a treatment period (combination therapy, single day), and an 84 day follow up period. A total of up to 11 visits will take place, all on an out-patient basis. For the LKA651 vs sham injections, the unmasked ophthalmologist is not permitted to do any of the assessments except for the injection (and an inspection of the injection site immediately following). All other ocular assessments after randomization will be conducted by a second ophthalmologist masked to the type of injection (active or sham). The Lucentis injection (Part 2) is given open label to all patients following either the LKA651 or sham injection. ;
