About this study

Official title: A One-month, Randomized, Single Centre, Double-masked, Comparative Study to Evaluate the Short-term Ocular Effects of Experimental BHVI2 and 0.02% Atropine Eye Drops Either Alone or in Combination

To assess the one-month ocular effects of nightly application of experimental BHVI2 and 0.02% atropine eye drops either alone or in combination, in children aged between 6 to 13 years old with myopia and randomized to use of experimental BHVI2 eye drops, 0.02% atropine eye drops, experimental BHVI2 plus 0.02% atropine eye drops.

Read the detailed description

Atropine was proven to be effective in controlling myopia. 7-methylxanthine was considered to play a role in slowing myopia. The experimental BHVI2 eye drops were proven to be safe for in-eye use in the trial that was conducted in Sydney, Australia. The investigators wish to evaluate the effects of experimental BHVI2 and 0.02% atropine eye drops either alone or in combination mainly on the pupillary and accommodative responses in children aged between 6 to 13 years old over a one-month period.

What is being measured

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

  1. Change in pupillary diameter

    Measure and compare the photopic and mesopic pupil size (milimeters) before and after instillation of eye drops

    Measured: At baseline, at two-week and one-month visits

  2. Change in accommodative amplitude

    Measure and compare the accommodative amplitude (diopters) before and after instillation of eye drops

    Measured: At baseline, at two-week and one-month visits

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Experimental BHVI2, Atropine sulfate 0.02% eye drops and Combination eye drops in people with Myopia, run by Hai Yen Eye Care at 1 site in Vietnam.

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 7 inclusion and 11 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 12 Feb 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 Vietnam. 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.

What does this 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.

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?

Change in pupillary diameter (time frame: At baseline, at two-week and one-month visits). 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?

On the ClinicalTrials.gov record for NCT03690414, which also lists 18 linked publications.

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 12 Feb 2020.
