Key Takeaways

Baricitinib and deuruxolitinib inhibit JAK1/2, while ritlecitinib targets JAK3 and TEC, reflecting different mechanisms of action in alopecia treatment.
Selective inhibition focuses on specific JAK pathways, potentially minimizing off-target effects and improving safety profiles.
Pan-inhibition affects multiple JAK pathways, which may enhance efficacy but also increase the risk of adverse effects.
Understanding the differences in JAK inhibitor selectivity is essential for optimizing therapeutic strategies in alopecia management.

Panelists discuss the differences in mechanisms of action among the FDA-approved Janus kinase (JAK) inhibitors for alopecia, including baricitinib, deuruxolitinib, and ritlecitinib, and explore how selective inhibition differs from pan-inhibition in influencing treatment efficacy.

Video content above is prompted by the following:

Three JAK inhibitors are FDA-approved for the treatment of alopecia: baricitinib and deuruxolitinib (JAK1/2 inhibitors), and ritlecitinib (selective JAK3 and TEC inhibitor). Can you talk about the differences in mechanisms of action and how they might influence treatment efficacy for alopecia?
