Clinical Study Timeline

The study completed enrolling patients on September 29, 2017. In total, 52 patients were treated with the Elevoplasty™ procedure in the trial. They and their bed partners are completing or have completed their six month study follow-up.

Zelegent expects that the final data point in the study will be collected in April 2018.

If the clinical results of this pivotal, multi-center trial are consistent with the results obtained in the single-center pilot trial performed in New York in 2015, the data will support a regulatory submission to the U.S. Food and Drug Administration (FDA) in 2018.

Note: Elevoplasty™ is an investigational procedure and the Elevo™ Kit Snoring Intervention Device is an investigational device only — not for sale in the U.S.
