A Trial to Investigate the Impact of Nocturnal Hypoglycaemia on Sleep in Subjects With Type 2 Diabetes

January 20, 2017 updated by: Novo Nordisk A/S
This trial is conducted in Europe. The aim of this trial is to investigate the impact of low blood sugar during the night on sleep in subjects with type 2 diabetes.

Description

Inclusion Criteria:

  • Type 2 diabetes mellitus (diagnosed clinically) for at least 24 weeks prior to screening
  • Currently treated with any anti-diabetic treatment (incl. diet and exercise) except insulin with a stable dose for more than 4 weeks prior to screening
  • Body mass index below 35 kg/m^2

Exclusion Criteria:

  • Severe hypoglycaemic event during the past 6 months or hospitalisation for diabetic ketoacidosis during the previous 6 months
  • Any other chronic disorder or severe disease by clinical information (including chronic obstructive pulmonary disease (COPD), sleep apnoea and epilepsy) which, in the opinion of the investigator might jeopardise subject's sleep, safety or compliance with the protocol, or subjects with mental incapacity or language barriers precluding adequate understanding or co-operation or who, in the opinion of the investigator, should not participate in the trial
  • Use of antidepressants, antipsychotics, hypnotics, sedatives or other drugs known to influence sleep within 12 weeks prior to screening

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
OTHER: Normoglycaemia followed by hypoglycaemia
Other: glucose clamp
Each subject will complete one adaptation night visit followed by two experimental night visits, one normoglycaemic and one hypoglycaemic, in randomised order. While subjects are asleep, sleep patterns will be monitored online using polysomnographic recordings during a hypoglycaemic and a normoglycaemic clamp (using constant intravenous (i.v.) infusion of human soluble insulin (Actrapid®)). Plasma glucose will be monitored.
