The study will investigate the impact of reduced renal function on the pharmacokinetic and pharmacodynamic profile of LEO 27847. Volunteers with different degrees of renal impairment will be administered one dose of the investigational drug and then followed until investigational drug is eliminated from the body.

Main Inclusion Criteria:

• Male and/or non-childbearing potential female, 18 years of age and older, healthy or with stable renal impairment (deemed stable by the referring physician for at least the last 4 weeks and not expected to change significantly during the next 3 months)

• BMI ≥18.0 and ≤ 42 kg/m2

• Patients with stable concomitant medical conditions

• Healthy subjects or patients with a creatinine clearance (at the time of screening) estimated using the formula of Cockcroft and Gault within the range of:

  • ≥ 50 to ≤ 80 mL/min (Mild Group: 8 subjects),
  • ≥ 30 to < 50 mL/min (Moderate Group: 8 subjects),
  • < 30 mL/min (Severe Group: 8 subjects).

Main Exclusion Criteria:

• Patients with renal transplants or currently on haemodialysis or peritoneal dialysis

• Clinically significant illness or surgery within 4 weeks prior to dosing

• Clinically significant ECG abnormalities or vital sign abnormalities at screening

• History of stroke, cerebrovascular disorder, coronary angioplasty and coronary bypass graft

• Clinically significant history or presence of any gastrointestinal pathology

  • multivitamins or vitamin D taken on a regular basis
  • topical products without systemic absorption

• Hemoglobin ≤ 90 g/L

• Serum total calcium (adjusted for albumin) level < 2.25 mmol/L

• Clinically significant history of congestive heart failure, cardiac dysfunction or liver disease
