A Study to Evaluate the Performance and Safety of CBL-101 Versus Vismed® Multi Eye Drops in the Management of Dry Eye

The primary objectives of this investigation are to show that the performance of CBL-101 Eye Drops is non-inferior to that of Vismed® Multi eye drops in subjects with moderate to severe keratoconjunctivitis sicca after 28 days, and to assess the safety of CBL-101 Eye Drops during a 90-day period with treatment administered 3 to 6 times per day.

Primary outcomes

  1. Change From Baseline in Ocular Surface Fluorescein Staining Score at Day 28

    Time frame: Baseline (Day 0), Visit 4 (Day 28)

    Mean change from baseline (CFB) in the study eye in Ocular Surface Fluorescein Staining (OSFS) scored according to the Oxford Scheme.

    The Oxford Scheme is a validated scale consisting of a series of panels labelled A to E in order of increasing severity. Grade 0 corresponds to panel A increasing to Grade 5 corresponding to more than Panel E, with punctate dots representing staining. The 3 regions, cornea, nasal and temporal bulbar conjunctiva are graded separately from 0 to 5, with the OSFS score ranging from 0 (best outcome) to 15 (worst outcome). The OSFS is the sum score of the 3 subscores (cornea, nasal and temporal regions).

    The study eye was the eligible eye with the highest OSFS score at baseline, which needed to be ≥4 and ≤9 on the 15-grade Oxford Scheme. If both eyes were eligible and had the same OSFS score, the study eye was the right eye.
