Efficacy and Safety of APP13007 for Treatment of Inflammation and Pain After Cataract Surgery Including a Corneal Endothelial Cell Sub-study

Phase 3
Completed
Conditions
Ocular Inflammation and Pain After Cataract Surgery
Interventions
Drug: APP13007, 0.05%
Drug: Matching Vehicle Placebo for APP13007, 0.05%
Registration Number
NCT04810962
Lead Sponsor
Formosa Pharmaceuticals, Inc.
Brief Summary

This Phase 3 study will evaluate APP13007 in comparison to the matching vehicle placebo in a randomized, parallel-group, double-masked fashion. The subjects will have undergone routine cataract surgery on Day 0 of the study and will be assessed the next day (Post-operative Day; POD1) after uncomplicated surgery for eligibility for randomization to study treatment. The study comprises the Main Study and the Endothelial Cell Sub-study.

Primary Outcome Measures
NameTimeMethod
Participants With ACC Count = 0 in the Operated Study Eye at All Visits From Postoperative Day 8 Through Postoperative Day 15 Without Rescue MedicationPostoperative Day 8 and Postoperative Day 15

The number of cells in the anterior chamber of the eye are counted using slit-lamp biomicroscopy at each study visit and the results are reported as number of cells in a 1mm x 1mm area.

Participants With Ocular Pain Grade = 0 in the Operated Study Eye at All Visits From Postoperative Day 4 Through Postoperative Day 15 Without Rescue MedicationPostoperative Day 4, Postoperative Day 8 and Postoperative Day 15

Ocular pain is measured in the eye using a subject-reported five-point (0-4) ocular pain grade scale (0 = no pain; 1 = minimal; 2 = mild; 3 = moderate; 4 = severe pain).

Participants With Treatment-emergent Adverse Events (AEs)From First dose to Postoperative Day 22 (End of Main Study)

Number of participants with ocular and systemic treatment-emergent AEs.

Secondary Outcome Measures
NameTimeMethod
Participants With Anterior Chamber Cell Grade = 0 in the Operated Study Eye at POD15 Without Rescue MedicationPostoperative Day 15

The number of cells in the anterior chamber of the eye are counted using slit-lamp biomicroscopy at each study visit and the results are reported as number of cells in a 1mm x 1mm area. ACC Grade 0 = 0 cells, ACC grade 1 = 1-5 cells, ACC grade 2 = 6-15 cells, ACC grade 3 = 16-30 cells, ACC grade 4 = \>30 cells.

Participants With Ocular Pain Grade = 0 in the Operated Study Eye at POD15 Without Rescue MedicationPostoperative Day 15

Ocular pain is measured in the eye using a subject-reported five-point (0-4) ocular pain grade scale (0 = no pain; 4 = severe pain).

Participants With Anterior Chamber Flare (ACF) = 0 in the Operated Study Eye at POD8 Without Rescue MedicationPostoperative Day 8

The degree of turbidity (flare) in the anterior chamber of the eye is measured using slit-lamp biomicroscopy and quantified on a five-point (0-4) anterior chamber flare grade scale (0 = none; 4 = Intense).

Participants With Ocular Pain Grade = 0 in the Operated Study Eye at POD4 Without Rescue MedicationPostoperative Day 4

Ocular pain is measured in the eye using a subject-reported five-point (0-4) ocular pain grade scale (0 = no pain; 4 = severe pain).

Participants With Anterior Chamber Flare (ACF) = 0 in the Operated Study Eye at POD15 Without Rescue MedicationPostoperative Day 15

The degree of turbidity (flare) in the anterior chamber of the eye is measured using slit-lamp biomicroscopy and quantified on a five-point (0-4) anterior chamber flare grade scale (0 = none; 4 = Intense).

Ocular Pain Grade in the Operated Study Eye - Change From Baseline (POD1 Prior to Dosing) to POD 15Baseline and Postoperative Day 15

Ocular pain is measured in the eye using a subject-reported five-point (0-4) ocular pain grade scale (0 = no pain; 1 = minimal; 2 = mild; 3 = moderate; 4 = severe pain).

Best Corrected Visual Acuity in the Operated Study Eye - Change From Baseline (POD1 Prior to Dosing) to POD8Baseline and Postoperative Day 8

The visual acuity in each eye is corrected using the pinhole method and the acuity is quantified on a logMAR (minimal angle of resolution) scale using the 'Early Treatment Diabetic Retinopathy Study' \[ETDRS\] charts for right and left eyes. A logMAR Score is calculated using the letter row on the chart and the number of incorrect letters read by the participant.

Best Corrected Visual Acuity in the Operated Study Eye - Change From Baseline (POD1 Prior to Dosing) to POD15Baseline and Postoperative Day 15

The visual acuity in each eye is corrected using the pinhole method and the acuity is quantified on a logMAR (minimal angle of resolution) scale using the 'Early Treatment Diabetic Retinopathy Study' \[ETDRS\] charts for right and left eyes. A logMAR Score is calculated using the letter row on the chart and the number of incorrect letters read by the participant.

Best Corrected Visual Acuity in the Operated Study Eye - Change From Baseline (POD1 Prior to Dosing) to POD4Baseline and Postoperative Day 4

The visual acuity in each eye is corrected using the pinhole method and the acuity is quantified on a logMAR (minimal angle of resolution) scale using the 'Early Treatment Diabetic Retinopathy Study' \[ETDRS\] charts for right and left eyes. A logMAR Score is calculated using the letter row on the chart and the number of incorrect letters read by the participant.

Participants Using of Anti-inflammatory 'Rescue' Medication Through End-of-TreatmentFirst dose to Postoperative Day 15

Participants who do not respond to study treatment after randomization are started on anti-inflammatory medication (referred to as 'Rescue' medication). The number of subjects starting 'Rescue' medication is recorded at each study visit
