Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to measure the safety, tolerability, PK, and PD of AZD5492 administered subcutaneously in adult participants with SLE or IIM or RA

Study details include:

• The study duration will be a minimum of 180 days in addition to the screening period.

Additional follow-up visits may be required up to 12 months from study start.

* Depending on the study part they are assigned to, participants will be administered AZD5492 once (Part 1) or twice (Part 2).
* Study visits will occur at:

Screening, Days 1-4, 8, 15, 22, 30, 60, 90, 120, 150, and 180 in Part 1, Screening, Days 1-4, 8-11, 15, 22, 29, 43, 60, 90, 120, 150, and 180 in Part 2.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

The decision to open Part 2 will be made by the Safety Review Committee (SRC) based on the evaluation of all available data including safety, tolerability, PK, and PD from Part 1 and pertinent data arising from other ongoing studies with AZD5492 will also be considered, and the dose levels and dosing strategy for Part 2 will be confirmed.

After a screening period of up to 42 days, participants will receive 1 dose of AZD5492 and be followed up for at least 179 days post-dose.

Part 2 - Step-up dosing (SUD) Part 2 will be a SUD design in adult participants who have SLE (and did not participate in Part 1), as well as adult participants with IIM or RA. In Part 2, participants will receive 2 dose administrations, 7 days apart. The first (priming) dose of the step-up regimen will be agreed by the SRC. The second (target) dose will be escalated, and a minimum of 3 target dose levels are planned to be investigated in Part 2.
