Efficacy and Safety of NVC-422 in the Treatment of Adenoviral Conjunctivitis


The purpose of this study is to evaluate the clinical and microbiological efficacy and safety of NVC-422 compared to vehicle for adenoviral conjunctivitis. Adults and children one year of age and older with diagnosis of adenoviral conjunctivitis in at least one eye based upon a positive adenovirus test result using the Aden-Detactor Plus kit (Rapid Pathogen Screening, Inc).

Subjects will be randomly assigned to receive either NVC-422 or Vehicle.

Detailed Description

This is a randomized (1:1) double-masked, vehicle-controlled, multi-center, parallel group study with two treatment arms: NVC-422 Ophthalmic Solution 0.33% ("NVC-422") and NVC-422 Vehicle ("Vehicle").

Subjects that meet all inclusion/exclusion criteria will be enrolled into the study, randomized and evaluated at 6 visits:

- Visit 1: Screening, Day 1

- Visit 2: Day 3

- Visit 3: Day 6

- Visit 4: Day 11 End of Treatment (EOT)

- Visit 5: Day 18 Test-of-Cure (TOC)

- Visit 6: Day 42 Follow-up

Subjects were dosed OU for 10 days. Specimens were collected OU at each visit for quantitative PCR adenoviral load and molecular typing.
