About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

  • Agree to follow the contraception requirements of the trial.
  • Able to give fully informed written consent.
  • Agree not to donate blood or blood products during the study and for up to 3 months after the administration of the trial medication.

  • Use of supplement(s) during the 28 days before screening.
  • Participation in other clinical trials of unlicensed medicines, or loss of more than 400 mL blood, within the previous 3 months.
