Participant Flow

Participants were recruited at Henry Ford Medical Hospital, Detroit MI, USA between October 2013 to December 2014.

43 subjects screened. 33 subjects received product (ie, enrolled, for the purposes of this reporting), of whom 2 withdrew but re-enrolled (per protocol amendment). These 2 subjects are counted as starting each sequence in the table below, bringing total started to 35 and for AEs to 30 and 29 (DPH and placebo, respectively.) 25 subjects completed.

PRIMARY outcome

Timeframe: 4 weeks

Population: Subjects with evaluable data for mean latency to persistent sleep for both treatment periods were included in the efficacy analysis provided they meet the other defined Per Protocol criteria. All data for each treatment and endpoint were averaged for all days in which the study medication was taken in a given treatment period.
