A Three Part Study of MGV354 in Ocular Hypertension or Glaucoma

Alcon Research191 enrolled

Overview

The purpose of this study is to determine if the clinical profile of topical-ocular MGV354 merits further development for the indication of lowering intraocular pressure (IOP).

Part 1 will evaluate the safety and tolerability of single ascending doses of MGV354 compared to placebo in healthy male and female subjects. Part 2 will evaluate the safety and tolerability of MGV354 in a multiple ascending dose design (two highest tolerated doses from Part 1) compared to placebo when administered for 7 days to patients with ocular hypertension or glaucoma. Part 3 will explore the safety, tolerability and efficacy of a single dose level of MGV354 (maximum tolerated dose) compared to placebo when administered for 7 days in patients with ocular hypertension or glaucoma.

Exclusion criteria: * History of hypersensitivity to any of the study drugs or to drugs of similar chemical classes; * History of or current presence of clinically significant ECG abnormalities or arrhythmias; * History of malignancy of any organ system (other than localized basal cell carcinoma of the skin or in-situ cervical or breast cancer), treated or untreated, within the past 5 years; * Known clinical history of heart failure, myocardial infarction, or stroke; * Exposure during the four weeks preceding the Screening visit to any topical, inhaled, or systemic corticosteroids; * Angle grade less than Grade 2 in either eye; * Any abnormality, including corneal thickness \> 620 microns, preventing reliable applanation tonometry; * Pregnant or lactating women and women of child-bearing potential; * Sexually active males must agree to use a condom during intercourse while taking drug and for 6 days after stopping MGV354 medication and should not father a child in this period; * Positive HIV, Hepatitis B Ag or Hepatitis C Ab test result at Screening; * Abnormal liver function tests; * History or presence of impaired renal function; * Part 1 (Healthy Volunteers): Use of any NEW prescription drugs or herbal supplements within four (4) weeks prior to initial dosing, and/or NEW over-the-counter (OTC) medication, dietary supplements (vitamins included) within two (2) weeks prior to initial dosing. * Parts 2 and 3 (Patients): Patients with related disease condition(s) including any form of glaucoma other than open-angle glaucoma and pseudoexfoliation and/or pigment dispersion components; patients who cannot safely discontinue use of all topical ocular and/or systemic IOP-lowering medication according to protocol-specified Washout Schedule; patients with ocular diseases or conditions as specified in the protocol; patients taking certain medications as specified in the protocol; * Other protocol-specified exclusion criteria may apply.

Outcomes

Primary Outcomes

Part 3: Change in Diurnal IOP (Averaged Over 8 AM, 10 AM, Noon, 4 PM, and 8 PM) From Baseline to Day 8

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. Diurnal IOP was defined as the average of the five time points measured (8 AM, 10 AM, noon, 4 PM, and 8 PM). Baseline diurnal IOP was the average of IOP measurements obtained at the 2 eligibility visits. Change from baseline was calculated by taking the change at each time point from baseline to Day 8 and averaging the available changes. A more negative change from baseline indicates a greater improvement, i.e., a reduction of IOP. Only one eye (study eye) contributed to the analysis.

Time frame: Baseline, Day 8

Part 3: Change in IOP From Baseline to Day 8 at 8 AM, 10 AM, Noon, 4 PM, and 8 PM

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. Baseline IOP was the average of IOP measurements obtained at the 2 eligibility visits. Change from baseline was calculated by taking the change at each time point from baseline to Day 8. A more negative change from baseline indicates a greater improvement, i.e., a reduction of IOP. Only one eye (study eye) contributed to the analysis.

Time frame: Baseline, Day 8

Secondary Outcomes

Part 3: Change From Baseline in IOP at 36 Hours and 48 Hours Post Day 7 Administration

IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and reported in mmHg. Baseline IOP was the average of IOP measurements obtained at the 2 eligibility visits. Change from baseline was calculated by taking the change at each time point from baseline to Day 8 and averaging the available changes. A more negative change from baseline indicates a greater improvement, i.e., a reduction of IOP. Only one eye (study eye) contributed to the analysis.

Time frame: Baseline, up to Day 9

Part 1: Maximum Observed Concentration [Cmax (ng/mL)]

Based on plasma samples collected at pre-determined nominal time points, dependent on observed concentrations. Approximately 2 mL of venous blood was collected at each time point. Cmax is reported as mass/volume.
