Brief summary
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

Eligibility
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 * Signed written informed consent in accordance with Good Clinical Practice (GCP) and local legislation * Age ≥ 18 and ≤ 50 years * 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 * Current or history of: gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunologic, autoimmune, hormonal disorders, diseases of the central nervous system (such as epilepsy), psychiatric disorders or cancer * Symptoms of a clinically relevant illness in the 3 weeks prior to planned administration of study drug * 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 * Intake of drugs with a long half-life (\> 24 hours) within 1 month prior to planned administration of study drug * Use of any drugs which might influence the results of the trial within 10 days prior to planned administration or during the trial * Participation in another trial with an investigational drug within 2 months prior to planned administration or during trial * Smoker (\> 10 cigarettes or 3 cigars or 3 pipes/day) or inability to refrain from smoking on study days * Current or history of drug, alcohol, tobacco or caffeine abuse * Blood donation within 1 month prior to planned administration or during the trial * Excessive physical activities within 5 days prior to planned administration of study drug or during the trial * Seropositivity for hepatitis B antigen (HBs-Ag), hepatitis C (HCV), HIV 1, or HIV 2 antibodies * Weight over 95 kg
