Brief summary
This Phase II study will evaluate the safety and efficacy of three fluoroquinolone ophthalmic agents to determine the optimal treatment in patients with infectious corneal ulcers.
Detailed description
This is a prospective, single masked, comparative, mono-therapeutic trial evaluating three fluoroquinolone agents that are approved and marketed for the treatment of conjunctivitis. Approximately 120 patients who have corneal ulcers greater than 2 mm but less than 6 mm in size who meet all other inclusion criteria will be enrolled into this study. Patients will be randomized in a 2:1:1 ratio to receive besifloxacin 0.6% ophthalmic suspension, gatifloxacin 0.5% ophthalmic solution, or moxifloxacin 0.5% ophthalmic solution.
Interventions
Drop to be applied in affected eye initially every hour for the first 48 hours then doses will be reduced at each subsequent visit by 50% if patient continues to show a reduction in size of 25% from the previous visit up to every 4 hours. If subject dose has been reduced to every 4 hours at visit 3 and shows an additional reduction size of 25% at visit 4, then they will be reduced to every 6 hours.
