Clinical Trial Summary

The main purpose of this study was to demonstrate that LML134 can increase wakefulness compared to placebo in patients with shift work disorder (SWD) measured by objective and subjective endpoints of wakefulness, i.e. the sleep latency in the multiple sleep latency test (MSLT) and the Karolinska Sleepiness Scale (KSS), respectively. Safety and PK of LML134 were also evaluated. In addition, novel methodologies to measure wakefulness and sleep were also to be tested and compared to gold standard methods like the MSLT and polysomnography (PSG) (at sites where staff have appropriate equipment and training). The aim of such comparisons was to evaluate the usefulness of the new technologies in clinical studies and provide preliminary validation data.

This was a randomized, subject and investigator-blinded, placebo controlled, crossover, multi-center Proof of Concept (PoC) study with in-house simulated laboratory night shifts in patients with SWD. This non-confirmatory study included two treatment arms: LML134 and placebo. After a screening period, the treatment phase of the study consisted of two overnight stays in a sleep lab in each of two treatment periods, with a minimum one week wash-out in between.

• Heavy caffeine consumers, i.e. subjects who consume greater than 850 mg of caffeine per day (approximate equivalent of three tall cups of Starbucks coffee) in coffee, tea, or other caffeine-containing drinks.

• Subjects who have high risk of obstructive sleep apnea, indicated by score of 5 or more on the STOP-BANG questionnaire.

• Presence of any sleep disorder other than SWD, as confirmed by PSG at screening.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean Sleep Latency Over Two Consecutive Test Nights as Measured by the the Multiple Sleep Latency Test (MSLT)	The Multiple Sleep Latency Test (MSLT) is an objective assessment of sleepiness that measures the ability of a subject to remain awake. Long latencies to sleep are indicative of a patient's ability to remain awake. Mean sleep latency from MSLT was measured for four MSLT naps performed at scheduled timepoints (01:30, 03:30, 05:30, and 07:30). The primary efficacy variable was the mean MSLT sleep latency assessed at Day 1 and Day 2 of each treatment period.	Day 1 and Day 2 of each treatment period (midnight until 8:00)
Secondary	Sleep Latency at Separate Naps Over Two Consecutive Test Nights as Measured by the the Multiple Sleep Latency Test (MSLT)	The Multiple Sleep Latency Test (MSLT) is an objective assessment of sleepiness that measures the ability of a subject to remain awake. Long latencies to sleep are indicative of a patient's ability to remain awake. Mean sleep latency from MSLT was measured for four MSLT naps performed at scheduled timepoints (01:30, 03:30, 05:30, and 07:30). The outcome measure is the mean value of Day 1 and Day 2 assessments for each timepoint.	Day 1 and Day 2 of each treatment period (midnight until 8:00)
Secondary	Plasma PK Concentration	Plasma PK concentration. Due to sparse sampling, only plasma concentrations were calculated and no PK parameter was evaluated by non-compartmental analysis.	0 to 34.5 hours post first treatment.
Secondary	Total Time in Bed Measured by Polysomnography (PSG)	PSG encompasses the monitoring of subjects in a sleep facility using an array of medical equipment with simultaneously recording on a multi-channel analog or digital system. PSG was performed in the study to record and evaluate various aspects of sleep.; Total time in bed is the time spent in bed during recording.	Day 2 (10:00 until 18:00) of each treatment period
Secondary	Sleep Time Measured by Polysomnography (PSG)	PSG encompasses the monitoring of subjects in a sleep facility using an array of medical equipment with simultaneously recording on a multi-channel analog or digital system.
