Detailed Description

Primary open angle glaucoma is a chronic progressive neurodegenerative disease and the only proven effective therapy involves reduction of intraocular pressure (IOP). Although treatment effect is quite large, a significant proportion of patients show disease progression with apparently controlled IOP. Given the similarities with other neurodegenerative diseases - particularly in the mechanisms of cell death -neuroprotective treatments have been tried also in glaucoma. Interesting results from experimental studies and weak evidence from human glaucoma trials have been published in recent years. Citicoline is one of the promising molecules with a putative neuroprotective action and has been tried on patients with a number of neurodegenerative diseases with encouraging results. Pilot studies on glaucomatous patients showed a possible effect of citicoline in reducing progression of visual field changes, though these findings need to be confirmed by larger randomized clinical trials.

The aim of this randomized, double-masked, placebo-controlled, cross-over study is to test whether the intake of Neurotidine® (citicoline free acid in oral solution) can be associated with an improvement of quality of life in patients with glaucoma.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

Patients must meet all the following criteria to be eligible for the study:

  • Signed written informed consent.
  • Age ≥ 18 years.
  • Patients with bilateral open-angle glaucoma (OAG). PEX and pigmentary glaucoma will be included.
  • Controlled IOP
  • Patients with moderate damage in the better eye, with mean deviation from normal value (MD) ranging from -6 to -12 dB in the 6 months prior to enrollment. At the screening assessment, MD must range from -5 to -13 dB.

Glaucoma definition will be based on visual field (VF) damage (24-2, SITA standard strategy) corresponding to glaucomatous changes at the optic nerve head. Values of IOP will not be an inclusion criterion, though a "controlled IOP" based on the clinician's judgement will be required.

Exclusion Criteria:

Patients must meet none of the following criteria to be eligible for the study:

  • Single-eyed patients (visual acuity <0.1 in one eye).
  • Patients without the psychophysical requirements to adequately participate and complete the trial.
  • Patients with chronic angle-closure glaucoma (CACG) or other types of glaucoma.
  • Patients with other ocular comorbidities interfering with the correct assessment of the glaucomatous damage to the VF.
  • Patients who have undergone surgery within 6 months.
  • Patients taking other potential neuroprotectors, including topical, competing with Neurotidine®.
  • Patients with Parkinson's disease, dementia or a diagnosis of stroke in the last 6 months.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The mean change of "intra-patient" global score of the Visual Functioning Questionnaire 25 (VFQ-25) after Neurotidine® vs placebo.
Time Frame: At 6 months compared to baseline
Primary outcome is based on the global score of the VFQ-25 questionnaire. Specifically, the VFQ-25 consists of a base set of 25 vision targeted questions. The global score derives from the summary of the scores deriving from each question. The total score has a minimum value "0" considered as the worst visual functionality, and the maximum value "100" considered as the better visual functionality.
At 6 months compared to baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The change of other scores of the questionnaire: Visual Functioning Questionnaire 25 (VFQ-25).
Time Frame: Up to 9 months compared to baseline
Other score utilized in the study: general health, general vision, near and far activities, social, mental, role difficulties, etc.
Up to 9 months compared to baseline
The change of other scores of the questionnaire: Short Form Health Survey - 36 items (SF-36).
Time Frame: Up to 9 months compared to baseline
Other score utilized in the study: general health, general vision, near and far activities, social, mental, role difficulties, etc.
Up to 9 months compared to baseline
The safety and tolerability of Neurotidine®.
Time Frame: Up to 9 months compared to baseline
The safety and tolerability of Neurotidine® will be detected on the basis of possible adverse events. In particular, they will be documented in the CRF. Possible adverse events will be communicated directly by the patient and/or detected by the Investigator during the medical examination.
Up to 9 months compared to baseline
