24-hour Efficacy and Tolerability of the Tafluprost-timolol Fixed Association Without Preservatives in Glaucomatous or Ocular Hypertensive Patients Already Treated With Latanoprost Preserved With BAK. A Prospective, Open Study of 3 Months Duration.

• Status: Recruiting
• Trial end date: 2022-06-30

• Participant gender: All

Summary

This is a phase IV, interventional, multi-center, open clinical Trial. Patients will be administered one eye drop of tafluprost/timolol fixed combination at 20:00 (+/- 1 hour), in the treatment of open angle glaucoma and ocular hypertension. The patients will suspend the treatment with latanoprost.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

• Lead Sponsor: Fondazione G.B. Bietti, IRCCS
• Treatments: Timolol

Criteria

Inclusion Criteria:

1. Ocular hypertension or primary open-angle glaucoma or secondary to dispersion of pigment or pseudoesfoliatio;

2. IOP <22 mmHg in latanoprost therapy in both eyes since at least 6 weeks and > 17 mmHg in at least one eye;

3. OSD at least mild as defined by DEQ-5 (score> 6);

4. Examination of the visual field during the three months prior to enrollment (if not present, the patient must be subjected to a visual field at the screening visit);

5. Treatment with latanoprost BAK-preserved from at least 6 weeks;

6. Subject agrees to follow the study procedures and signs the EC-approved ICF;

7. For women of child-bearing potential, blood screening for beta-HCG before randomization and use of one effective method of birth control during the conduct of the study

Exclusion Criteria:

1. Inability to understand and sign informed consent;

2. Age under 18 years;

3. Other forms of secondary glaucoma (besides pigmentary and pseudoesfoliatius);

4. Narrow angle or history of acute glaucoma attacks;

5. Previous history of trabeculoplasty in the previous 6 months;

6. History of glaucoma surgery or refractive surgery;

7. Cataract surgery in the 6 months prior to enrollment;

8. Contraindications to the use of beta-blockers (reactive airway disease, including bronchial asthma or a history of bronchial asthma, severe chronic obstructive pulmonary disease; sinus bradycardia, sick sinus syndrome, including sinoatrial block, second or third degree atrioventricular block not controlled by pacemaker; full-blown heart failure, cardiogenic shock);

9. Damage to the visual field with a mean deviation (MD) <-20 dB;

10. BCVA <2/10;

11. Topical ocular drugs performed within 3 months prior to enrollment that may interfere with the study results (eg steroids, non-steroidal anti-inflammatory drugs, immunosuppressants, etc.);

12. Use of tear substitutes containing preservatives within 30 days prior to enrollment;

13. Any other condition that, in the opinion of the investigator, may compromise the safety or compliance of the patient or would preclude the patient from successful completion of the study or would impair interpretation of results;

14. Corneal anomalies that preclude an accurate measurement of IOP (eg astigmatism> 3 D, keratoconus, opacity or corneal ulcers);

15. Any type of previous corneal or conjunctival surgery including pterygium removal or refractive surgery;

16. Unstable systemic disorders that may require the initiation or variation of therapies that may influence intraocular pressure during the study;

17. Woman of childbearing potential, or who is currently pregnant or breastfeeding;

18. Inability to adhere to the procedures required by the protocol or to the studio treatment;

19. Participation in another experimental therapeutic protocol within one month prior to baseline and during the study period (participation in natural history study is allowed);

20. Hypersensitivity to the active substances or to any of the excipients.
