Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43718   clinical trials with a EudraCT protocol, of which   7255   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.3Principal inclusion criteria
    •Male or female patients 18 years of age or older diagnosed with open-angle glaucoma or ocular hypertension who are currently on one or more IOP-lowering medications and, in the opinion of the investigator, would benefit from one of the combination therapies.
    •Patients must meet the following IOP entry criteria in at least one treated eye: (1) For the qualifying treated eye(s), the mean IOP must be greater or equal to 24 mmHG at 9 AM and 21 mmHG at 4 PM on the Eligibility Visits 1 and 2, (2) The mean IOP in either eye must not be greater than 36 mmHg at any time point, (3) The same eye(s) must qualify at both time points at the Eligibility Visits 1 and 2.
    •Patients must be able to discontinue use of all IOP-lowering medication(s) for a minimum period of 5 days ± 1 day, to 28 days ± 1 day prior to the Eligibility Visit 1.
    •Only patients who satisfy all informed consent requirements may be included in the study.
    E.4Principal exclusion criteria

    •Patients with any form of glaucoma other than open-angle glaucoma or ocular hypertension.
    •Patients who are currently on therapy or were on therapy with another investigational agent within 30 days prior to the Eligibility 1 Visit.
    •History of chronic recurrent, or current severe inflammatory eye disease (i.e., scleritis, uveitis, herpes keratitis) in either eye.
    •History of, or current other severe ocular pathology (including severe dry eye) in either eye or serious hypersensitivity to prostaglandin drugs or their analoques, that would preclude the administration of a topical prostaglandin analogue, carbonic anhydrase inhibitor, or beta-blocker.
    •Patients who cannot safely discontinue their glucocorticoid medications administered by any route.
    •History of spontaneous or current hypoglycaemia or uncontrolled diabetes.
    •Any abnormality preventing reliable applanation tonometry of either eye.
    •History of, or current clinically relevant or progressive retinal disease.
    •History of intraocular trauma or surgery within the past six months.
    •Patients with less than 30 days stable dosing regimen before the Screening Visit of any non-glaucoma medications.
    •History of, or current bronchial asthma, severe chronic obstructive pulmonary disease, or severe unstable or uncontrolled cardiovascular, hepatic or renal disease.
    •Patients with best-corrected visual acuity worse than 0.6 logMAR score in either eye.
    •Patients with angle grade less than Grade 2 measured by gonioscopy.
    •Patients with a cup/disc ratio greater than 0.80 in either eye.
    •Additionally, the Medical Monitor may declare any patient ineligible for a valid medical reason.
    E.5 End points
    E.5.1Primary end point(s)
    The primary statistical objective of this study is to demonstrate that the IOP-lowering efficacy of dosing Travoprost 0.004%/Timolol 0.5% Ophthalmic Solution (once-daily morning dosing) is superior to Dorzolamide 2%/Timolol 0.5% Ophthalmic Solution, dosed twice-daily.
