Mirtogenol and Bimatoprost on IOP in Hispanics With Open-Angle Glaucoma

A prospective, parallel-group, double-blind, randomized placebo-controlled clinical study will be conducted with an estimated 72 participants. The objective of this study is to determine if Mirtogenol has an additive effect on the reduction of intraocular pressure when combined with bimatoprost in the Hispanic population with primary open angle glaucoma. Baseline clinical data will be collected for each participant and they will be randomized 1:1 to a treatment group (bimatoprost 0.01% and Mirtogenol) or control group (bimatoprost 0.01% and placebo). Efficacy and safety of Mirtogenol will be measured during the 24 week study. Participants will be evaluated in five visits: screening and baseline, week 4, week 8, week 12 and week 24. The tests that will be performed include visual acuity, visual field evaluation, applanation tonometry, optical coherence tomography (OCT), and pachymetry. Side effects or adverse effects will be reported and evaluated by the ophthalmologist at each visit to access the safety of Mirtogenol. The primary efficacy endpoint of intraocular pressure (IOP) will be compared using a t-test and will have an 80% probability to detect a difference between treatments at a 0.05 significance level.

METHODOLOGY AND STUDY DESIGN A prospective, parallel-group, double-blind, randomized placebo-controlled clinical trial will be conducted with an estimated 72 primary open-angle glaucoma patients. A double blind RCT was chosen to minimize bias and yield similar groups with the same prognostic at baseline to avoid compromising the validity of the study results. The primary efficacy endpoint of the study will be IOP and the secondary endpoint will be the safety analysis. Qualifying participants will be evaluated for inclusion and exclusion criteria by their ophthalmologist (Dr. Marino Blasini) and informed about the study objectives. If they agree to participate, relevant baseline clinical data will be collected for each participant and they will be assigned to a treatment or a control group by stratified randomization based on their age, intraocular pressure and cup-to-disk ratio. This stratified randomization will allow comparability of randomized study groups at baseline. Participants will be randomized in a 1:1 ratio to treatment group (bimatoprost 0.01% and Mirtogenol®) or control group (bimatoprost 0.01% and placebo) and be assigned a participant ID number. Once the randomization process has concluded, participants will be notified to pass by the office to receive the product and to start using the Mirtogenol® or placebo the next day. Both Mirtogenol® and placebo bottles will label drug of study and be registered with a number identification for each patient. Mirtogenol and the placebo will be stored in a destinated area in the primary investigator's pharmacy under a cool, dry environment that protects them from extreme temperature changes and light. Oral and written instructions on drug regimen, including route of administration, frequency, proper storage and mode of administer will be provided. The groups will self-instill one drop of bimatoprost 0.01% in the affected eye(s) once daily as instructed by the ophthalmologist. In addition, participants will use one (1) capsule of Mirtogenol® or one (1) placebo capsule orally daily in the morning with food. Mirtogenol® will be funded by Life Extension Clinical Research, Inc. Placebo capsules will be similar in appearance, size, and route of administration to Mirtogenol®. The study will have five visits: screening and baseline, week 4, week 8, week 12 and week 24 of approximate 30-60 minutes of duration and an addition visit for pickup of the product after the randomization process. An ophthalmological evaluation will be conducted by a glaucoma specialist at each visit. At the baseline visit, the following tests will be performed: visual acuity, visual field evaluation, applanation tonometry, optical coherence tomography (OCT), and pachymetry. At week 4, and week 8 the following tests will be performed: visual acuity and applanation tonometry. At week 12, the following tests will be performed: visual acuity, visual field evaluation and applanation tonometry. At week 24, assessments will include the following: visual acuity, visual field evaluation, applanation tonometry, optical coherence tomography and pachymetry. The same equipment will be used throughout the study for measurement consistency. Each test will be measured in the morning and the patient will be resting, sitting for at least 10 minutes before measurement. The tests will always be performed by the same person to rule out variations. At each visit, the IOP will be measured twice, with 10-minute intermissions between measurements, and mean values will be recorded. If only one eye is determined eligible as trial eye (meeting the diagnostic criteria for glaucoma), then all assessments will be performed only for the trial eye. If both eyes are eligible, only the eye with highest baseline mean IOP will be included in the statistical analysis. Patients will be instructed not to take any medications within two hours before measurements. Any therapy considered necessary for the patient's welfare will be given at the discretion of the treating physician and will be documented. Safety measures include non-invasive techniques, standard of care treatment during the duration of the study, ophthalmological evaluations and assessment tests. Side effects or adverse effects will be reported and evaluated by the ophthalmologist at each visit and if deemed necessary the trial medication (Mirtogenol® or matching placebo) will be discontinued and therapy adjusted as appropriate by the clinician. Adverse effects will be recorded at each study visit as well as the probability of possible association of the adverse effects to the treatment. Compliance will be reinforced with daily reminder for a month by email or text messages and then weekly reminders until the termination of the study. A monthly calendar will be provided to keep track of doses and possible miss doses. Patient must bring their supplement or placebo bottles and monthly track calendar to each visit and a pill count will be performed. Participants will be contacted one month after discontinuing the trial medication to assess for any prior changes or side effects.
