Patient-Reported Hair Loss and Its Impacts as Measured by the Alopecia Areata Patient Priority Outcomes Instrument in Patients Treated with Ritlecitinib: The ALLEGRO Phase 2b/3 Randomized Clinical Trial.

ABSTRACT:

Background

The ALLEGRO phase 2b/3 study investigated the efficacy and safety of ritlecitinib in patients with alopecia areata (AA).

Objective

To describe the impact of ritlecitinib on patient-reported hair loss using the Alopecia Areata Patient Priority Outcomes (AAPPO) instrument and evaluate the relationship between clinically meaningful hair regrowth and improvements in patient-reported impacts.

Methods

In ALLEGRO-2b/3, patients aged ≥ 12 years with AA and ≥ 50% scalp hair loss received once-daily ritlecitinib 50 or 30 mg (± 4-week 200-mg daily loading dose), 10 mg, or placebo for 24 weeks and then continued ritlecitinib or switched from placebo to ritlecitinib 200/50 or 50 mg for 24 weeks. The AAPPO instrument evaluated improvement in hair loss, emotional symptoms
