LML-134

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.
