NCT02111122

Brief Summary

Sleep wake disturbance is a common problem in Parkinson's disease patients and so far the therapeutic possibilities for symptomatic relief are limited. Small, open-label studies indicate that the use of Xyrem (gamma-hydroxybutyrate) might be of benefit in this situation. This study is intended to show a beneficial effect of the study medication in a randomized cross-over trial, that fulfills strict scientific criteria.

Study Arms (2)

Sodium Oxybate

EXPERIMENTAL

Treatment (500mg Natrii oxybas/ml) will be administered every day at night time for 6 weeks each orally by the patient itself. If necessary, the investigator will make sure that a relative or caregiver is able to assist in daily treatment administration. The dosage starts at 3g per night and is adapted in steps of 1.5g during visits and telephone screenings and always noted in the "medication log-book". The maximal dosage is 9g per night.

Drug: Sodium Oxybate

Placebo

PLACEBO COMPARATOR

Treatment will be administered every day at night time for 6 weeks each orally by the patient itself. If necessary, the investigator will make sure that a relative or caregiver is able to assist in daily treatment administration. As with the active compound, placebo will be given with a starting dose of 3g per night and is adapted in steps of 1.5g during visits and telephone screenings and always noted in the "medication log-book". The maximal dosage is 9g per night.

Drug: Placebo

  • Women who are pregnant or breast feeding,
  • Intention to become pregnant during the course of the study,
  • Lack of safe contraception, defined as:
  • Female patients of childbearing potential, not using and not willing to continue using a medically reliable method of contraception for the entire study duration, such as oral, injectable, or implantable contraceptives, or intrauterine contraceptive devices, or who are not using any other method considered sufficiently reliable by the investigator in individual cases.
  • Please note that female patients who are surgically sterilized/hysterectomized or post-menopausal for longer than 2 years are not considered as being of child bearing potential.
