A Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of ION904

Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: ION904; Drug: Placebo

• Registration Number: NCT04731623
• Lead Sponsor: Ionis Pharmaceuticals, Inc.

Brief Summary

The purpose of this study is to assess the safety and tolerability of ION904.

Detailed Description

This is a Phase 1, randomized, double-blind, placebo-controlled, single-ascending dose escalation study of ION904 in up to 72 participants. Following a Screening Period of up to 28 days, eligible healthy participants will be randomized to treatment and receive a single, subcutaneous (SC) dose of the assigned study drug. Participants will be followed for up to 13 weeks after dosing.
