Clinical Trial: Proof of Concept Study to Evaluate Safety and Efficacy of LME636 in the Treatment of Acute Anterior Uveitis
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: A Multicenter, Randomized, Double-Masked, Active-Controlled Study to Evaluate the Safety and Efficacy of LME636 in Patients With Acute Anterior Uveitis
Brief Summary: The purpose of the study is to determine whether topical ocular administration of LME636 60 mg/mL is efficacious in resolving the ocular inflammation in the anterior chamber associated (AC) with acute anterior uveitis (AAU).
Detailed Summary: Eligible subjects will be randomized to LME636 or Dexamethasone in a 3:1 ratio at the time they present to the trial site with the AAU flare and will enter treatment for 28 full days. Subjects with worsening disease from Visit 2/Day 4 onward or subjects without improvement after 14 days of treatment will be discontinued from treatment, unmasked and treated with a rescue regimen at the discretion of the investigator.

Current Primary Outcome:
- Number of Subjects with Reduction from Baseline in AC cell grade of ≥2 at Day 15 [ Time Frame: Baseline (Day 1), Day 15 ]Anterior chamber cells will be graded as per Standardization of Uveitis Nomenclature (SUN).
- Mean Best Corrected Visual Acuity (BCVA) at Each Visit [ Time Frame: Up to Day 29 ]Visual Acuity (VA) will be measured with the subject's best spectacles or other visual corrective device in place using an ETDRS or Snellen visual acuity chart.
- Mean Intraocular Pressure (IOP) at Each Visit [ Time Frame: Up to Day 29 ]IOP (fluid pressure inside the eye) will be assessed using Goldmann applanation tonometry or Tonopen.
- Number of Subjects with a 1 Grade or More Worsening Score from Baseline in Slit Lamp Parameters at Each Visit [ Time Frame: Baseline (Day 1), Up to Day 29 ]Ocular signs (lids/lashes, conjunctiva, cornea, anterior chamber, iris, and lens) will be assessed by slit-lamp biomicroscopy.
- Number of Subjects with a 1 Grade or More Worsening Score from Baseline in Dilated Fundus Parameters at Each Visit [ Time Frame: Baseline (Day 1), Up to Day 29 ]Fundus parameters (vitreous, retina, macula, and optic nerve) will be analyzed by dilated examination.
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Number of Subjects with IOP Elevation at Each Visit [ Time Frame: Baseline (Day 1), Up to Day 29 ]IOP will be assessed using Goldmann applanation tonometry or Tonopen. IOP elevation is defined as an increase of ≥10 mmHg from baseline and ≥21 mmHg.
- Mean Change from Baseline in BCVA at Each Visit [ Time Frame: Baseline (Day 1), Up to Day 29 ]Visual Acuity (VA) will be measured with the subject's best spectacles or other visual corrective device in place using an ETDRS or Snellen visual acuity chart.
- Time-to-Response [ Time Frame: Baseline (Day 1), Up to Day 29 ]Response is defined as reduction from Baseline in AC cell grade of ≥2. Time-to-response will be presented as the number of subjects with first response by visit.
- Use of Rescue Treatment [ Time Frame: Up to Day 29 ]Use of rescue treatment will be presented as the number of patients with first use of rescue treatment by visit.
- Mean Serum Concentration of Total LME636 at Each Visit [ Time Frame: Up to Day 29 ]Determination of the concentration of total LME636 in serum will be performed using an immunoassay.
- Number of Subjects with Anti-LME636 Antibodies Present at Each Visit [ Time Frame: Up to Day 29 ]Serum samples will be collected and assessed for anti-LME636 antibodies.
Original Secondary Outcome: Same as current
