Abstract

GEn significantly improved the International Restless Legs Scale total score by 12.3 points for the no-to-moderate sleep disturbance group.

  • GEn 600 mg and 1200 mg both showed significant improvements in IRLS total scores compared to placebo for adults with moderate-to-severe primary restless legs syndrome.
  • In the severe-to-very severe sleep disturbance group, GEn led to a mean change of -16.6 and -17.0 points, respectively, compared to -12.7 with placebo.
  • A higher proportion of patients treated with GEn met the criteria for 'much'/'very much' improved on the Clinical Global Impression-Improvement scale compared to those on placebo.
  • GEn also resulted in notable improvements in mood and pain scores for both sleep disturbance subgroups when compared to placebo.
  • The most common side effects reported were somnolence and dizziness.
