In group three, 25 patients will be instructed to scrub the lid margin of one eye with 5% PI and the other eye will receive 1 drop of azithromycin ophthalmic solution twice daily for 10 days. In group four, 25 patients will be instructed to scrub the lid margin of one eye with 5% PI and the other eye will receive tobradex ointment applied to the lid margin. Subjective variables assessed included itchiness, foreign body sensation and eyelid edema (grade 0-4). Objective variables assessed included lid margin redness, meibomian gland plugging and presence/absence of collarets (grade 0-4). Cultures of lid margin at the initiation and at the cessation of treatment were obtained.

Clinical Trials Update

Current Status of Clinical Investigations

As of 2023, there are no ongoing or recent major clinical trials specifically targeting TOBRADEX ST registered on ClinicalTrials.gov. Historically, clinical research emphasized safety, efficacy, and comparative studies for bacterial infections and inflammatory ocular conditions.

Parameter	Details
Number of active trials	0 (per latest registry data)
Past clinical studies	Focused on safety profile, resistance potential, and efficacy in bacterial conjunctivitis (e.g., NCT01894591, completed in 2014)
Regulatory updates	No recent IND applications or supplementary NDA filings identified
Adverse event monitoring	Consistent with known profile; minimal reports of antimicrobial resistance development

Implications of Trial Data

The absence of recent clinical trials indicates that TOBRADEX ST’s development focus may have shifted from clinical experimentation toward post-market surveillance and generic competition. Nonetheless, ongoing research in similar medications suggests potential future studies in resistance management or formulation optimization.
