Efficacy and Safety of JAK Inhibitors in Patients With AA: RWE Study

August 25, 2024 updated by: Second Affiliated Hospital, School of Medicine, Zhejiang University

Efficacy and Safety of JAK Inhibitors in Patients With Alopecia Areata: a Single-center, Real-world Study

The introduction of Janus Kinase inhibitors (JAKi) seems to revolutionize the field of alopecia areata (AA) therapeutics. However, the ideal JAKi is not yet settled and the real-world data are still missing. To provide evidence about effectiveness and safety of different JAKi including tofacitinib, baricitinib, ritlecitinib，abrocitinib, upadacitinib and ifidancitinib in real-world settings and describe baseline disease characteristics and patients profiles that are considered good candidates for JAKi in the daily practice. Furthermore, we intended to investigate the efficacy and safety of JAK Inhibitors in patients With AA, as well as to provide clinical evidence for the clinicians and patients when they formulate individualized treatment plans.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
