First-in-Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of PRS-080

Phase 1

Completed

• Conditions: Healthy
• Interventions: Drug: PRS-080#022-DP; Drug: PRS-080-Placebo#001

• Registration Number: NCT02340572
• Lead Sponsor: Pieris Pharmaceuticals GmbH

Brief Summary

Anticalins® are engineered human proteins that are able to bind specific target molecules. The Anticalin PRS-080#022-DP to be investigated in this study is directed against hepcidin and is intended for treatment of anemia of chronic disease. This phase I First-in-Human study shall investigate safety and pharmacokinetics in healthy human volunteers.

Detailed Description

First-in-Human (FIH), randomized, dose-escalation, double-blind, placebo-controlled single dose in healthy volunteers.

The single rising dose study will enroll 8 subjects per cohort (6 verum, 2 placebo), up to a maximum tolerated dose, defined by stopping rules. 6 dose levels are anticipated. Study drug will be administered as i.v. infusion on Day 1. The decision to escalate the dose by the dose escalation committee (DEC) will be based on an interim analysis of clinical safety and safety laboratory data.
