About this trial

This clinical study is aimed at evaluating the safety and effectiveness of 2 test formulations (Rain and Mist), against an approved over-the-counter formulation (Systane Ultra) and a placebo (saline), in the treatment of moderate dry eye disease.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Be at least 18 years of age at the Screening Visit;

Of either gender and any race;

Be willing and able to follow all instructions and attend all study visits;

A corneal fluorescein staining score of ≥ 2 in at least one corneal region OR have a sum of ≥ 4 in all corneal regions

Disqualifiers

Have a known hypersensitivity to any of the procedural agents or study drug components, or have previously used the study drug;

Have clinically significant corneal epithelial defects at Visit 1, prior to performing Schirmer's Test;

Have had any intraocular surgery (such as cataract surgery) or extraocular surgery in either eye within three months, or refractive surgery (e.g., laser-assisted in-situ keratomileusis, laser epithelial keratomileusis, photorefractive keratectomy or corneal implant) within twelve months of Visit 1;

Have had blepharoplasty in either eye;

Treatments tested in this trial

  • Two test formulations for the treatment of DED are being compared against the approved OTC formulation (Systane Ultra) and saline (placebo).

    Drug

    Rain and Mist are the test formulations. Systane Ultra is an approved OTC formulation. Saline is the placebo.
