Brief Summary:
The purpose of this study is to define the dose for a Phase II study and to investigate safety and tolerability of intravenous administration of recombinant soluble human Angiotensin Converting Enzyme 2 in healthy volunteers.

Condition or disease Intervention/treatment Phase
Pulmonary Diseases Cardiovascular Diseases Kidney Diseases Cancer Diseases Biological: APN01 Other: Placebo Phase 1

Detailed Description:
APN01-1-01 is a placebo controlled double blinded Phase I study composed of a single dose, dose escalation part followed by a multiple dosage part. The first four cohorts (four individuals each) will receive 100, 200, 400 and 800 µg/kg APN01 i.v. or placebo. Cohorts 5 and 6 (three individuals each) will receive three and six i.v. APN01 administrations daily, respectively. Planned dosage of the multiple dose part will be 400 µg/kg.

Primary Outcome Measures :
  1. Safety and tolerability profile of APN01 when administered as a single dose / multiple dose i.v. in healthy volunteers. Measures: Blood chemistry, Hematology, Urinalysis, Adverse events, Vital signs including blood pressure, pulse, respiratory rate, ECG [ Time Frame: 31 Days ]

Secondary Outcome Measures :
  1. To obtain pharmacokinetic and pharmacodynamic data for APN01 and to investigate potential immunogenicity of APN01. Measures: Systemic rhACE2 concentration and activity, potential humoral immune response, Angiotensin II and Angiotensin 1-7 plasma levels. [ Time Frame: 31 days ]
