About this study

Official title: Clinical Trial Protocol for Safety and Efficacy of Soft Contact Lens (Model: Spherical Lens)

This project is a multi-center, randomized, parallel-controlled, non-inferior clinical trial of soft contact lenses.

Read the detailed description

The test product is the Soft Contact Lens (model: Spherical Lens), and the control product is a commercially available soft contact lens (model: SiHy Daily). The number of enrolled subjects is 148, and clinical observation is performed for 3 months.

What is being measured

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

  1. The ratio of corrected visual acuity of left and right eyes is ≥5.0

    The standard logarithmic visual acuity chart consistent with the guiding principle is adopted in this scheme.

    • Success criteria: If the lower limit of 95% CI of the evaluated rate of corrected for visual acuity for both eyes ≥ 5.0 at 1 week visit is ≥-10%, the primary endpoint of the two groups is non-inferior.

    Measured: 1 week

  2. The occurrence of adverse events

    Compare the number of adverse events and serious adverse events, the number of cases and the incidence rate; list the number and cases of adverse events; describe the adverse events that are related to the investigational products.

    Measured: 3 month

Secondary outcomes (1)
  1. BCVA (spectacles) and BCVA (CL)

    BCVA (spectacles and CL) of both eyes are compared at baseline and at each follow-up.

    Measured: 1 week, 1 month, 3 months

Questions about this trial

What is this clinical trial studying?

A study testing Contact Lenses in people with Myopia, run by Menicon Co., Ltd. at 1 site in China.

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 6 inclusion and 13 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 6 Mar 2020. 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 China. 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?

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?

The ratio of corrected visual acuity of left and right eyes is ≥5.0 (time frame: 1 week). 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 6 Mar 2020.
