About

The study was planned to be conducted in 2 parts: Part 1 to determine the efficacy and safety of ECF843 vs vehicle, followed by Part 2 with additional exploratory assessments of ECF843 vs Vehicle. Both parts of the study included a double-masked study design, with randomization stratified for subjects with Sjogren's Syndrome.

Full description

Part 1 of the study was a double-masked, randomized, parallel design in which participants were assigned to one of the following five treatment arms/groups in a ratio of 1:1:1:1:1.

ECF843 0.45 mg/mL three times daily (TID) or vehicle ECF843 0.15 mg/mL TID or vehicle ECF843 vehicle TID ECF843 0.15 mg/mL twice daily (BID) or vehicle ECF843 vehicle BID The planned duration of double-masked treatment during Part 1 was 56 days. For subjects randomized to ECF843, the maximum drug exposure was up to 28 days. At some point during Part 1, all participants received vehicle.

The study was terminated after completion of Part 1 and Part 2 of the study was not therefore initiated.
