What researchers measure

Primary outcomes

  1. Efficacy of ADX-102 on the Ora Calibra® Discomfort & 4-Symptom Questionnaire for Dryness.

    Change from baseline comparison of ADX-102 to Vehicle on the Ora Calibra® Discomfort \& 4-Symptom Questionnaire (0 = least, 5 = most) for dryness across all time points. The intervention was administered bilaterally. The Least Squares Mean (Standard Error) was derived from Mixed Model Repeated Measure for change from baseline calculated using baseline score, visit, treatment, and visit-by-treatment interaction.

    Time frame: Efficacy assessment period (Day 1 through Day 85) - assessed on Days 1, 15, 29, 57, and 85.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2018 to primary completion in Jul 2018, 6 months.

Results were first posted in Feb 2025, 6 years 6 months after primary completion. A results delay was requested in Jul 2019.

Of 75 industry-sponsored phase 2 interventional studies under Dry Eye Syndromes, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 11. This study's 6 months is below that.

Counting every sponsor, half of 90 studies reached it within 7 months; a quarter within 5 and three quarters within 12.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 6, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
