What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To demonstrate that the fixed combination of latanoprost and timolol has a better IOP-reducing effect than the individual monotherapies.

    Measured: 6 months

Secondary outcomes (8)
  1. To examine, within treatment groups, the diurnal IOP reducing effect from baseline for all treatments at Week 26

    Measured: 6 Months

  2. To compare the diurnal IOP reducing effect from baseline between the monotherapies latanoprost and timolol at Week 26

    Measured: 6 Months

  3. To compare the number of treatment failures and patients withdrawn due to uncontrolled IOP from baseline to Week 26 between treatment groups

    Measured: 6 Months

  4. To compare the proportion of patients reaching pre-specified (15, 18, and 21 mmHg) target diurnal IOPs between the treatment groups at Week 26

    Measured: 6 Months

  5. To describe the IOP development from baseline to Week 26 for all treatment groups

    Measured: 6 Months

  6. To compared the IOP reducing effect from baseline to Week 26 of the monotherapies with the IOP reducing effect from Week 26 to Week 52 of the fixed combination

    Measured: 6 Months

  7. To examine, within the fixed combination treatment group, the diurnal IOP reducing effect from baseline to Week 26 and Week 52

    Measured: 6 Months

  8. To follow the safety variables throughout the study periods.

    Measured: 6 Months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing i. Fixed combination of latanoprost 0.005% and timolol 0.5%, timolol 0.5% ophthalmic solution and latanoprost 0.005% ophthalmic solution in people with Ocular Hypertension and Glaucoma, run by Pfizer's Upjohn has merged with Mylan to form Viatris Inc. at 37 sites in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 37 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To demonstrate that the fixed combination of latanoprost and timolol has a better IOP-reducing effect than the individual monotherapies. (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Feb 2021.
