Further study details as provided by Apeiron Biologics:

Primary Outcome Measures:

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:

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 ]


Estimated Enrollment:	22
Study Start Date:	April 2009
Study Completion Date:	December 2009
Primary Completion Date:	November 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Active Comparator: APN01 Healthy volunteers will receive APN01	Biological: APN01 APN01, a physiological formulation of recombinant human Angiotensin Converting Enzyme 2 administrated i.v.
Placebo Comparator: Placebo Physiological saline administrated i.v.	Other: Placebo Physiological saline administrated i.v.

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.
