A Randomised, Double-blind, Placebo-controlled Phase 1 Single Ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Subcutaneously Administered SLN124 in Healthy Volunteers

This study will evaluate the safety and tolerability of SLN124 in healthy volunteers.

This first-in-human (FIH) study will investigate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of SLN124 after single ascending s.c. doses in healthy male and female subjects.

Up to 3 cohorts of 24 healthy volunteers will be enrolled. Each subject will receive a single dose of SLN124 or placebo given by subcutaneous (s.c) injection.
