Trial Summary

What is the purpose of this trial?

The purpose of this randomized, controlled, multicenter study is to evaluate the safety and efficacy of TTAX03 in participants with mild to moderate DED. The primary question it aims to answer is if TTAX03 is safe. The secondary is the effectiveness. Researchers will compare 10mg of TTAX03 reconstituted in 150, 300, or 600 uL saline to the saline control group to look at effectiveness. Participants will be randomized to a treatment group one time and be evaluated at 5 different study visits.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are using a nasal cholinergic agonist or topical glaucoma medication, you may need to stop as these are listed in the exclusion criteria.
