Description
This is an open-label, multi-centre Phase I study to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of AZD5492 in adult participants with either SLE or IIM or RA. The study consists of 2 parts: Part 1 - Single ascending dose (SAD) Part 1 will be a sequential SAD design in adult participants with SLE. Up to 5 dose levels of AZD5492 are planned to be investigated. Depending on emerging data, up to 4 additional dose levels may be added at the discretion of the Sponsor.
