About this study

Official title: A Randomized, Parallel-Group, Multi-Center, Investigator-Masked, Active-and Placebo-Controlled, Phase 1-2 Evaluation of the Safety and Efficacy of OT-730 Ophthalmic Solution in Reducing the Intraocular Pressure in Subjects With Ocular Hypertension or Open-Angle Glaucoma

The purpose of this study is to evaluate the safety and potential efficacy of a new drug, OT-730 ophthalmic solution (eye drops), in reducing intraocular pressure in the eyes of patients with open angle glaucoma or ocular hypertension. It will be compared with commercial timolol and placebo eye drops.

Read the detailed description

Glaucoma is a group of diseases of the eye that can result in irreversible vision loss due to damage to the optic nerve. Elevated intraocular pressure (IOP) is one factor associated with glaucoma. Currently-available medication used to lower IOP includes beta-blocking agents, which can have undesirable side effects on the cardiac and respiratory systems.

The OT-730 ophthalmic solution contains OT-730, a prodrug that, when applied as an eyedrop, metabolizes to OT-705, an active beta blocker. The OT-730 ophthalmic solution is being studied to see how well it lowers IOP in patients with a diagnosis of open angle glaucoma or ocular hypertension. It will be compared with a well known beta blocker, timolol maleate ophthalmic solution, and with a placebo eye drop, in order to assess its ability to lower IOP without the typical side effects of other beta blockers.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing OT-730 ophthalmic solution and timolol maleate ophthalmic solution in people with Glaucoma, Open-Angle and Ocular Hypertension, run by Othera Pharmaceuticals at 5 sites in United States.

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 10 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 7 Jan 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Assess the safety profile of OT-730 (time frame: 8 days). The study lists 2 primary outcomes in all. 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 7 Jan 2009.
