About this study

This will be a controlled and randomized, single-masked, crossover study in which 48 subjects will use the Biofinity Contact Lens (comfilcon A) with each of the two lens care products ('solutions'), (Synergi and Biotrue Multi-purpose Solution) for one month each. Follow-up visits for each solution will take place at one week, two weeks and four weeks: with a one-week 'wash-out' period between the solutions. Key outcome measures for this study include biomicroscopic and subjective responses to the lens/solution combinations.

Questions about this trial

What is this clinical trial studying?

A study testing comfilcon A, Synergi and Biotrue in people with Myopia, run by CooperVision, Inc. at 1 site in United Kingdom.

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 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 1 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Feb 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Conjunctival Hyperaemia (time frame: Baseline, 1 week, 2 weeks, 4 weeks). The study lists 17 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 1 Feb 2017.
