Key exclusion criteria
1.Any history of clinically significant cardiac arrhythmias or the presence of clinically significant abnormalities on ECG at screening.2.Any evidence or history of hypotension or hypertension. Hypotension is defined as three separate readings that persistently read under 90/60 mmHg. Hypertension is defined as three separate readings that persistently read over 140/90 mmHg.3.Tumours or fractures as the cause of pain.4.Diabetes as defined as fasting blood glucose levels = 7mM.5.A history or evidence of any other clinical neuropathy.6.Diagnosed Rheumatoid Arthritis.7.Pain anywhere else of an equal or greater intensity than the sciatica-related pain.8.Admission for Heart Failure, a Myocardial Infarction, Transient Ischaemic Attack or Cerebrovascular Accident within the 6 months prior to Day 1.9.Patients with a clinical condition that may, in the opinion of the Investigator, impact on the patient’s ability to participate in the study, or on the study results10.A calculated creatinine clearance of less than 75 mL/min.11.Documented or reported history of Hepatitis B, Hepatitis C, or HIV infection. NOTE – these will not be tested for.12.Any evidence of organ dysfunction, or any deviation in clinical laboratory values which is confirmed on re-examination to be clinically significant (i.e. in the opinion of the Investigator would jeopardise the safety of the patient or impact on the validity of the study results), including a liver function test (LFT) > 1.5 x upper limit of normal (ULN). Total bilirubin levels > 1.5 x ULN will be allowed if associated with Gilbert’s syndrome.13.History of, or current evidence of, abuse (in the investigator’s opinion) of alcohol or any licit or illicit drug substance.14.Known poor compliers or those unlikely to attend study visits.15.Receipt of any drug as part of a research study within 30 days of Day 1.16.Standard blood donation (usually 550 mL) within the 12-week period prior to Day 1.
