Brief Summary:
Acute adenoviral conjunctivitis is a highly contagious, widespread endemic disease associated with frequent outbreaks, significant patient discomfort, lost productivity, and in some cases permanent visual compromise from long-term immune mediated sequelae. OKG-0301 is a novel ophthalmic solution with a potent ribonuclease that has broad-spectrum antiviral properties relevant for the treatment of acute adenoviral conjunctivitis. This randomized, double masked, multi-center Phase 2 study is being conducted entirely within Australia and is designed to support the safety and efficacy of OKG-0301 for the treatment of acute adenoviral conjunctivitis. The study intends to show superiority of OKG-0301 Ophthalmic Solution compared to vehicle for the primary efficacy endpoint of mean change from baseline in viral titre in patients with acute adenoviral conjunctivitis. Secondary efficacy endpoints including adenoviral eradication, clinical cure of acute adenoviral conjunctivitis, subepithelial infiltrates, other clinical signs and symptoms, and rate of cross-over infection to the other eye will also be assessed. Safety will also be evaluated.

Primary Outcome Measures :
  1. Mean change from baseline in viral titre levels in the study eye [ Time Frame: Day 7 ]
    PFU


Secondary Outcome Measures :
  1. Clinical Cure as Measured by the Absence of Bulbar Conjunctival Injection [ Time Frame: Day 4, 7 and 14 ]
    Clinical cure of acute adenoviral conjunctivitis as measured by the absence (score = 0) of bulbar conjunctival redness (graded using the validated Ora Calibra Scale 16.2: Bulbar Conjunctival Redness Grading Scale)

  2. Clinical Cure as Measured by the Absence of Watery Conjunctival Discharge [ Time Frame: Day 4, 7 and 14 ]
    Clinical cure of acute adenoviral conjunctivitis as measured by the absence (score = 0) of watery conjunctival discharge (graded on a scale of 0-3 based on severity, developed specifically for this trial)

  3. Adenoviral eradication (CC-IFA) [ Time Frame: Day 4, 7 and 14 ]
    Adenoviral eradication is defined as negative CC-IFA. CC-IFA will be conducted using conjunctival swab samples collected at each visit to determine the presence or absence of adenovirus.

  4. Adenoviral eradication (PFU) [ Time Frame: Day 4, 7 and 14 ]
    Adenoviral eradication is defined as zero plaques in cultures of ocular samples. PFU will be conducted using conjunctival swab samples collected at each visit to determine the presence or absence of adenovirus.

  5. Severity of subepithelial infiltrates [ Time Frame: Day 4, 7 and 14 ]
    Evaluation of SEIs in study eye, assessed under slit lamp exam with Investigator grading on a 0-3 semi-quantitative scale (developed specifically for this study).

  6. The rate of cross-over infection [ Time Frame: Day 4, 7 and 14 ]
    Clinical signs in contra-lateral eye that initially presented with no signs or symptoms of adenoviral conjunctivitis

  2. Be willing and able to follow all instructions and attend all study visits.
  3. Have a clinical diagnosis of suspected acute adenoviral conjunctivitis in at least 1 eye and the presence of both of the following minimal clinical signs in that same eye:

    • Bulbar conjunctival redness: a minimum grade of '1' on 0-3 scale
    • Watery ocular discharge: a minimum grade of '1' on a 0-3 scale
  4. Patient reported presence of signs and symptoms consistent with adenoviral conjunctivitis equal to or less than 3 days in same eye prior to Visit 1.
  5. Have a positive AdenoPlus® test at Visit 1 in the same eye that meets the minimum 1+ grade for bulbar conjunctival redness and watery ocular discharge.
  6. Be willing to discontinue contact lens wear for the duration of the study.

Exclusion Criteria:

Each patient MUST NOT:

  1. Have known sensitivity or poor tolerance to any component of the study medications or diagnostics.
  2. Have a history of ocular surgical intervention or trauma within 12 weeks prior to Visit 1 or planned for the period of the study.
