Abstract

BACKGROUND

Alopecia areata (AA) is a hair loss disorder that can seriously impact quality of life. Janus kinase (JAK) inhibitors, including deuruxolitinib, have previously demonstrated significant hair regrowth in AA.

OBJECTIVE

The Phase 3 THRIVE-AA1 randomized, double-blinded, placebo-controlled trial (NCT04518995) evaluated safety and efficacy of the oral JAK1/JAK2 inhibitor deuruxolitinib in adult patients with AA.

METHODS

Patients aged 18-65 years with ≥50% hair loss were randomized to deuruxolitinib 8 mg BID, deuruxolitinib 12 mg BID, or placebo for 24 weeks. The primary endpoint was percentage of patients achieving Severity of Alopecia Tool (SALT) score ≤20. A key secondary endpoint was percentage of satisfaction of hair patient-reported outcome (SPRO) responders.

RESULTS

Significantly higher proportions of patients taking deuruxolitinib met the primary endpoint (8 mg 29.6%; 12 mg 41.5% versus placebo 0.8%). Both deuruxolitinib doses achieved significant improvements in all secondary endpoints versus placebo, including SPRO (8 mg 42.1%; 12 mg 53.0% versus placebo 4.7%). Most treatment-emergent adverse events were mild or moderate, consistent with other oral JAK inhibitors.

LIMITATIONS

Further studies are required to understand longer-term safety, efficacy, and impact of treatment cessation.

CONCLUSION

Both doses of deuruxolitinib were effective for hair regrowth. Patient satisfaction aligned with hair growth.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
