Evaluation of the Safety and Tolerability of Ocular Lubricants
- Conditions
- Dry Eye Disease
- Registration Number
- NCT06571656
- Lead Sponsor
- Alcon Research
- Brief Summary
The purpose of this study is to evaluate the safety and tolerability of three new artificial tear formulations in subjects with moderate dry eye disease.
- Detailed Description
This study will be conducted in 2 stages. In Stage 1, subjects will attend a total of 10 scheduled visits: one Screening visit, four Investigational Product visits, four 12-hour Follow Up visits (one for each Investigational Product visit), and an Exit visit. At each Investigational Product visit, subjects will receive one drop of the investigational product in each eye (2 drops total), as randomized. The first Investigational Product visit will occur 1 to 7 days after the Screening visit. A washout period of 2 to 7 days will separate each Investigational Product visit. Total individual duration of participation in Stage 1 will be 8 to 34 days. The planned enrollment for Stage 1 is 72 subjects.
At the conclusion of Stage 1, an interim analysis will be conducted to help determine potential adaptations to the study design for Stage 2.
This study will be conducted in Australia.

- Primary Outcome Measures
Name Time Method Number of Treatment-Emergent Adverse Events (AEs) Visit 2 (1 to 7 days after the Screening Visit) through Visit 6/Study Exit. Visit 6 will occur 7 to 27 days after Visit 2 depending on observed visit windows. An AE is any untoward medical occurrence, unintended disease or injury, or untoward clinical signs (including abnormal laboratory findings) in subjects, users, or other persons, whether or not related to the investigational medical device (test product). The number of adverse events as observed or reported will be recorded.
Number of Subjects with Biomicroscopy Findings Outside of Normal Limit Screening Visit through Visit 6/Study Exit. Visit 6 will occur 8 to 34 days after Screening Visit, based on observed visit windows. The investigator will observe the corneal and other ocular structures under white light of the slit lamp. The number of subjects with biomicroscopy findings outside of normal limits will be recorded.
Best Corrected Visual Acuity (BCVA) Screening through Visit 6/Study Exit. Visit 6 will occur 8 to 34 days after Screening Visit, based on observed visit windows. BCVA will be assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) letter charts and recorded in logarithm Minimum angle of resolution (logMar).
