About this study

Official title: A Dispensing Clinical Trial of Invigor 1 Daily Disposable Lens Against Clariti 1-day Lens

The purpose of this study is to compare the dispensing performance of somofilcon A test 1 day contact lens against somofilcon A control 1 day contact lens.

Read the detailed description

The purpose of this study is to evaluate the clinical performance of a silicone-hydrogel test contact lens compared to the commercially available silicone-hydrogel (control) contact lens when worn over one week for each lens type in a randomized, bilateral, cross-over, dispensing study on a daily disposable basis.

Questions about this trial

What is this clinical trial studying?

A study testing Test lens in people with Myopia, run by CooperVision, Inc. at 2 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 11 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What does the primary outcome measure?

Number of Participants With Lens Centration (time frame: Baseline). The study lists 14 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 18 Jun 2020.
