Modulation of Neuronal Connettivity Along the Visual Pathways in Patients Affected by Glaucoma Throug Treatment With Citicoline Oral Solution: Multimodal Morpho-funcional Study
In Brief
A clinical study evaluating Citicoline and Placebo for Primary Open Angle Glaucoma. Active but no longer recruiting, targeting 29 participants across 2 sites.
Detailed Summary
A prospective, multicentre, randomized, blinded, masked study that involves the enrollment of 60 patients affected by open angle glaucoma (OAG). Patients selected according to the inclusion / exclusion criteria, after signing the informed consent, will be randomized into two groups: 1. In a group of patients with OAG, Citicoline in oral solution (10 ml / day, Neurotidine®) will be administered for 12 months (Citicoline Treated Group, TC Group) 2. in another group of patients with OAG will be administered Placebo (Containing all excipients of Neurotidine ®) (10 ml / day) for 12 months (Placebo Treated Group, TP Group) Randomization will be done by dividing the selected patients into two groups based on similar characteristics of: age, perimetric defect and, mainly, retinal-cortical time (RCT) values. Patients will be assigned to each group by an investigator not involved in functional and structural testing. The key will be opened only at the end of the treatment in order to evaluate the first effects. The Primary Objective was to evaluate whether treatment with Citicoline in oral solution can produce an improvement of the post-retinal neural conduction, that is delayed in patients with OAG. The Secondary objective was to evaluate in patients with OAG whether the possible changes in post-retinal neural conduction induced by treatment with Citicoline in oral solution (information obtained through electrophysiological recordings) are associated or not with morphological and functional variations of the nervous structures forming the visual pathways (nucleus geniculatus lateral, optic tract, visual cortex, information obtained through the acquisition of structural and functional magnetic resonance imaging) and whether both conditions can be related to the morpho-functional variations of the retinal ganglion cells and of the visual field (VF).

Timeline
Interventions
The patient will be given 10 ml of Citicoline oral solution (Neurotidine ®) once a day in the morning for 1 year. To patients will be given 4 bottles containing 500 ml of Citicoline and the relative instructions for administration. After 6 months, the patient will bring back the used bottles and will be given additional 4 bottles containing Citicoline (Neurotidine ®). Again at the end of this 6 month period the patient will bring back the used bottles. Each bottle of Neurotidine will contain: water; fructose; Citicoline (500 mg per 10 ml); acidity regulators: sodium citrate, sodium hydroxide; preservative: potassium sorbate; dye: riboflavine.
The patient will be given 10 ml of an oral solution of Placebo. Each bottle of Placebo, the solution of which will be indistinguishable from the active product in terms of appearance and flavor, will contain: water; fructose; acidity regulators: sodium citrate, sodium hydroxide; preservative: potassium sorbate; dye: riboflavin
