Pharmacokinetics and Pharmacodynamics of BIWH 3 in Healthy Duffy Positive vs. Duffy Negative Male Volunteers

Pharmacokinetics and Pharmacodynamics of BIWH 3: a Randomised, Placebo-controlled, Double Blind Dose Escalation Study (0.02, 0.06, 0.2, 0.6, and 2.0 μg/kg Intravenous Over One Hour) in Healthy Duffy Positive vs. Duffy Negative Male Volunteers

Study to compare the pharmacokinetic and pharmacodynamic effects of escalating dosages of recombinant human pyro-Glu MCP-1 (BIWH 3) in Duffy positive vs. Duffy negative healthy male volunteers: plasma levels of monocyte chemotactic protein-1 (MCP-1) and markers of leukocyte, coagulation, platelet and endothelial activation will be quantified; To examine the safety of BIWH 3 in this setting

Inclusion Criteria:

• Healthy male subjects as determined by results of screening
• Erythrocyte Fy positive and negative individuals because expression of the Duffy (Fy) receptor may influence MCP-1 plasma levels in humans

• Body mass index: ≥18 kg/m2 and < 30 kg/m2
• Normal findings in medical history and physical examination unless the investigator considers an abnormality to be clinically irrelevant
• Normal laboratory variables unless the investigator considers an abnormality to be clinically irrelevant
• Normal pharmacodynamic variables as determined at baseline visit
• Normal response to glucose tolerance test

Exclusion Criteria:

• Any finding in the medical examination (including blood pressure, pulse rate and ECG) deviating from normal and of clinical relevance

• History of orthostatic hypotension, fainting spells and blackouts
• Chronic or relevant acute infections
• History of allergy / hypersensitivity (including drug allergy) which is deemed relevant to the trial as judged by the investigator
• Any Electrocardiogram (ECG) value outside the reference range of clinical relevance including, but not limited to QRS interval > 110 ms or QTcB > 450 ms
