Official Title: Efficacy and Safety of 2mg/Day of M100907 on Sleep Maintenance Insomnia With a Sub-study of the Effect of M100907 on Stable Type II Diabetes Mellitus: a One Year, Multi-center, Randomized, Double-blind, Placebo-controlled Study

Further study details as provided by Sanofi:

Primary Outcome Measures:
  • Efficacy: change from baseline for Sleep Maintenance Insomnia using patient reported Wake After Sleep Onset (pr-WASO) [ Time Frame: at 3 months ] [ Designated as safety issue: No ]
  • Efficacy (sub-study): change from baseline for glycemic measure HbA1c [ Time Frame: at 6 and 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Efficacy: change from baseline of the pr-WASO [ Time Frame: at 6 and 12 months ] [ Designated as safety issue: No ]
  • Efficacy: change from baseline of "General Productivity" domain score of the Functional Outcomes of Sleep Questionnaire [ Time Frame: at 3 months ] [ Designated as safety issue: No ]
  • Safety: adverse events and laboratory abnormalities [ Time Frame: during 12 months of treatment ] [ Designated as safety issue: Yes ]
