Glaucoma, Open-Angle Clinical Trial
Official title:
Clinical Evaluation of the Antioxidant and Neuroprotective Effects of CoQ10-MINIACTIVES® (COQUN® OS) 100 mg BID Oral Administration in Patients Affected by Primary Open Angle Glaucoma (POAG): a Randomized, Double Blind Study
This is a randomized, double blind study with competitive enrolment, aimed to enroll a total
of 70 patients with a diagnosis of primary open angle glaucoma (POAG).
Patients, after signing the Informed Consent, will enter into a 1- week screening phase
during which the baseline tests will be conducted.
Subjects will be randomized in a 1:1 ratio to the following groups:
- group A of 35 patients treated with pressure lowering drugs and placebo;
- group B of 35 patients with pressure lowering drugs and COQUN oral formulation 100 mg
BID.

Inclusion criteria: - Patient Informed consent form (ICF) signed - M & F Aged = 40 and = 80 years at the time of the signature of ICF - Patients with Primary Open Angle Glaucoma (POAG) stage early-moderate according to Hodapp-Parrish-Anderson criteria (MD less than -12 dB) - Patients must be diagnosed with POAG at least 1 year before the screening visit in this study. - Anamnesis with at least 1 value of Intraocular pressure (IOP) >21mmHg documented any time prior the initiation of the stable treatment with anti-hypertensive topical drugs. - Patients affected by POAG and under stable treatment with anti-hypertensive topical drugs in the previous 6 months prior to enrolment to maintain IOP =18 mmHg. - Corrected visual acuity (using ETDRS tables) = 8/10 - Transparent dioptric means to allow the examination of the OCT >25 µm. - Pachymetry values between 500 and 600 µm. - Patients have to show a stable visual field in the previous 6 months prior to enrolment (where by stable visual field it is intended that the patient must remain within the same stage of POAG severity (i.e. early or moderate) during the previous 6 months before the enrolment). - Willing to follow all study procedures, including attending all site visits, tests and examinations. - Women must agree to be using two forms of effective contraception, be post-menopausal from at least 12 months prior to trial entry, or surgically sterile. Exclusion criteria: - Patients with a severe defect of POAG according to Hodapp-Parrish-Anderson criteria. - Previously diagnosed optic neuropathies. - Diabetic retinopathy or Hypertensive retinopathy. - Decompensated diabetes. - Not stabilized hypertension (SAP and/or DAP) despite under adequate pharmacological treatment. - Retinal pathologies including hereditary forms. - Neurological, neurodegenerative or cerebrovascular conditions. - No previous history or presence of any disease involving cornea or retina. - Patients with a significantly progressive opacity of lens in the previous 3 months prior to enrolment (where by significant progressive opacity of lens it is intended patients who have been diagnosed with cataracts of any aetiology and for whom surgery is being considered). - No surgical intervention for cataract in the previous 3 months prior to enrolment. - Eye inflammatory conditions (uveitis) diagnosed any time in the patient's history. - Treatment with topical or systemic neuroprotective agents different from CoQ10. These patients can be admitted in the study after at least a 1 month of wash-out period. - Treatment with warfarin. - Treatment with miotic drugs able to influence the visual field. - Treatment with systemic or topical steroids. - Refractive defects beyond the 5 spherical diopters, both positive and negative and over 3 cylindrical. - Any clinically significant history of serious digestive tract, liver, kidney, cardiovascular, cancer or hematological disease. - Known drug and/or alcohol abuse. - Mental incapacity that precludes adequate understanding or cooperation. - Participation in another investigational study or blood donation within 3 months prior to ICF signature. |
