Unpacking JAK Inhibitors at RAD 2025

At the 2025 Revolutionizing Atopic Dermatitis (RAD) Meeting in Nashville, Dr. Leon H. Kircik, a leading expert in dermatology and medical director at Skin Sciences, PLLC, delved into the pivotal role of Janus Kinase (JAK) inhibitors in managing atopic dermatitis.

The Advantages of JAK Inhibitors

In his discussion, Kircik highlighted the standout feature of JAK inhibitors: their rapid efficacy. "Oral JAKs work incredibly fast," he noted. However, he cautioned about the serious safety concerns reflected in the boxed warnings associated with these medications, particularly when compared to traditional systemic therapies and biologics.

Navigating Safety Concerns

Addressing the critical boxed warnings, Kircik advised healthcare providers to educate themselves about the origins of these alerts. He explained that the warnings stem from studies involving tofacitinib, previously tested in rheumatoid arthritis patients, which highlighted safety issues especially in older adults with cardiovascular history.

Topical JAK Inhibitors: A Safer Alternative?

While safety issues persist in the broader JAK class, Kircik reassured that topical formulations like ruxolitinib present minimal absorption risks. "Unless you're eating the cream, you have nothing to be concerned about," he emphasized, reinforcing the relative safety profile of topical JAKs.

A Double Standard?

Interestingly, Kircik pointed out a paradox: oral ruxolitinib, approved for myelofibrosis, lacks the boxed warning attributed to its topical counterpart. This discrepancy underscores the complexities within the drug class and the impact of regulatory norms on patient treatment.

Conclusion: The Path Forward

As the field of dermatology evolves, it is crucial for both practitioners and patients to stay informed about the latest developments in JAK inhibitor therapy. With ongoing research and updates from conferences like RAD, the future of atopic dermatitis treatment looks promising, albeit with caution.
