| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To investigate whether the administration of Exenatide (10mcg BD by subcutaneous injection) in obese patients with type 2 diabetes without sleep apnoea (excluded by in-patient multi channel sleep study) but with symptoms of excess daytime sleepiness and suboptimal glycaemic control (hAb1c >7.5%), would result in a significant improvement in objective measure of daytime sleepiness and wakefulness (as determined by the sustained attention test (OsLer test).  This will be a proof concept study where patients undergo a fixed-order design allocation of placebo for 10 weeks followed by exenatide for 10 weeks. |  | 
| E.2.2 | Secondary objectives of the trial | 
| To investigate whether ten weeks administration of Exenatide (10mcg BD by subcutaneous injection) in obese patients with type 2 diabetes without sleep apnoea would result in a significant improvement in driving performance (assessed using a driving simulator), levels of ‘somnogenic cytokines’ (e.g. interleukin-6, TNF-alpha), Hba1c, weight and waist circumference |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| Inclusion Criteria •	Type 2 diabetes, on a stable medication regimen
 •	Excess daytime sleepiness (Epworth score >9)
 •	HbA1c 7.5-12.0%.
 •	Age 18-65 years
 •	BMI 28-40
 •	Subjects would have undergone a sleep study in the sleep laboratory at the Sherwood Forest Hospitals Foundation Trust and sleep apnoea has been excluded.
 
 |  | 
| E.4 | Principal exclusion criteria | 
| Exclusion Criteria •	Patients with congestive heart failure, depression, cancer, central nervous system demyelinating disorders, recurrent or active infection.
 •	HbA1c <7.5% or >12%)
 •	Age <18 or >65 years
