The patients will be randomized into two groups and given either the study drug or the placebo at the time of enrollment. The patients will come for weekly visits during which slit lamp photograph of the dendrite will be taken. At week 2, if the dendrite has not healed the drug will by unmasked and rescue therapy will be given. the patients will be examined at week 1, 2, and 3 or until resolution occurs.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 8 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

What does this phase mean?

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.

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?

Corneal Ulcer Healing (time frame: 2 weeks). 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 8 Jul 2021.
