Clinical Trial Summary

Aim of this study is to investigate the administration effects of the combination of citicoline 40mg/ml and nicotinamide 15mg/ml oral solution (Kron®) on short term improvement in inner retinal function, bioelectrical activity of the visual cortex and visual function.

Description:

Prospective, masked, randomized placebo-controlled study to evalute the offect of the oral solution Kron® (citicoline 40mg/ml and nicotinamide 15mg/ml) on patients with a diagnosis of open angle glaucoma and risk of glaucoma progression.

Glaucomatous patients with a diagnosis of open angle glaucoma and risk of glaucoma progression who meet the study criteria will be enrolled and randomly assign to the following two arms:

1. Treatment group (TG): 20 patients will receive Citicoline 40 mg/ml + Nicotinamide 15 mg/ml oral solution for 3 months (10 ml/day)

2. Control group (CG): 10 patients will be evaluated as control

Once recruited, a clinical evaluator will perform a comprehensive ophthalmologic evaluation at baseline, week 6 and week 12. The following examinations will be done in the following sequence:

• Visual acuity

• Slit lamp evaluation

• PERG

• PEV pattern

• Tonometry

• Visual field

• Optical Coherence Tomography

• Dilated Fundus examination

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Electrofunctional evaluation	Short term improvement in inner retinal function and bioelectrical activity of the visual cortex evaluated by means of PERG (P50 and N95 peaks) and PEV (P100 implicit time and N75-P100 amplitude) pattern.	3 months
Secondary	VF and SD-OCT	Visual field examination will be performed at the beginning and at the end of trial. Standard pattern short-term improvement in visual function in treated patients evaluated by means of VF. Retinal nerve fiber layer thickness, ganglion cell complex thickness and minimum rim width will be evaluated at the baseline and at the end of the study.	3 months
