Study summary

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

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

What researchers measure

Primary outcomes

  1. Change in glaucomatous damage

    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.

    Time frame: Baseline and Visit at 36 months

Secondary outcomes

  1. progression of glaucoma in the SD OCT examination

    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.

    Time frame: Baseline and Visit at 36 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2015 to primary completion in Mar 2019, 41 months.

Of 272 non-industry interventional studies with no phase under Glaucoma, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 55. This study's 41 months is above that.

Counting every sponsor, half of 355 studies reached it within 29 months; a quarter within 15 and three quarters within 55.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 16, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
