Evaluation of the Tolerability and Efficacy of CWT-f-002 Lubricant Eye Drops

In this study CWT-f-002 lubricant eye drop is being evaluated in subjects with dry eye. This OTC eye drop has previously shown promising results in multiple preclinical and clinical settings. The active comparator for this study is Systane (R). Ingredient lists as follows. CWT-f-002: Active Ingredients are glycerin 0.7% and polyethylene glycol 400 0.4%. Inactive ingredients are mannitol, polylysine-graft-polyethylene glycol, sterile water for injection, and sodium phosphate buffer. Systane: Active ingredients are polyethylene glycol 400 0.4% and propylene glycol 0.3%. Inactive ingredients are boric acid, calcium chloride, hydroxypropyl guar, magnesium chloride, potassium chloride, purified water, sodium chloride, zinc chloride. Systane (R) may contain hydrochloric acid and/or sodium hydroxide to adjust pH. Both products are preservative free and supplied in unit dosers.
