Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Double-blind, Placebo-controlled Dose-escalation Phase I Study With Recombinant Human Soluble Angiotensin Converting Enzyme 2 (rhACE2) APN01 in Healthy Volunteers

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 ] [ Designated as safety issue: Yes ]

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 ] [ Designated as safety issue: No ]

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.
