The Efficacy of Citicoline in Eyedrops (OMK1) in Reducing the Progression of Glaucoma

Double-blind study (OMK1 vs. Placebo) A total of 90 patients, 30 per center, will be the study sample. The study will include patients with Primary Open angle Glaucoma (glaucoma or pseudoexfoliation) with a loss of visual field with MD between -2 dB and -15 decibel.

Patients will be randomized into 2 treatment groups, both treated with hypotonic ocular drug therapy: one part of the patients will be treated with the OMK1 Medical Device containing topical citicoline for 3 years; the remaining part will receive a placebo.

All patients will be followed with quarterly visits which will check, in addition to the intraocular pressure (IOP), the structure of the optic nerve and visual function (standard visual field).

The primary objective is to evaluate a reduction of the perimetric progression in the group that receives the topical citicoline compared to the group treated with placebo. The reduction of the progression will be evaluated with Spectral Domain Optic coherence tomography and with standard perimetry (SAP).

The secondary objective is to assess the tolerability and safety of OMK1 eye drops.

Inclusion criteria

Patients with POAG and pseudoexfoliation glaucoma in one or both eyes. In the latter case, only one eye (chosen at random) will be used for the analysis.
Patients with -2 < MD < -15 dB, progression of MD at least -0,5 dB/y for 2 years.
Patients with tonometric compensation, i.e., IOP not above 18 mmHg. Tonometric compensation can be achieved with any type of hypotonic medical therapy and must be maintained during the 3 years of the study. If at any check-up the average of at least 3 measurements of IOP at different times is higher than 18 mmHg, the patient will be offered a new hypotonic treatment (including surgery) to control the progression of the disease. If compensation cannot be achieved (e.g., the patient refuses the proposed therapy or, in spite of this does not achieve satisfactory IOP values), the patient will be excluded from the study.
Patients over the age of 18 years

Exclusion criteria

Patients with contraindications to citicoline
Patients with IOP higher than 18 mmHg
Patients with other forms of glaucoma
Patients treated with other neuroprotective therapies
Women who are pregnant and/or breastfeeding
Pediatric or adolescent patients aged under 18 years

Treatment and study plan

Device

(OMK1) will be prescribed in the dosage of 1 drop 3 times a day

will be prescribed in the dosage of 1 drop 3 times a day

Primary outcomes

Change in glaucomatous damage

Time frame: Baseline and Visit at 36 months

The primary objective of the study is to assess whether there is a difference in the deterioration of glaucomatous damage with standard perimetry (HFA 24-2 and 10-2) in the group that receives the topical citicoline in addition to topical therapy with hypotensive drugs compared to the group treated with the sole reduction of intraocular pressure.

Secondary outcomes

progression of glaucoma in the SD OCT examination

Time frame: Baseline and Visit at 36 months

assessment of the progression of glaucoma in the SD OCT examination (Retinal Nerve fiber Layer- RNFL evaluation) in the group that receives the topical citicoline together with ocular antihypertensive drug therapy compared to the group treated with the sole reduction of intraocular pressure.

It will be used for the assessment of the progression of glaucoma the Brusini staging system.
