INCREASED SCALP HAIR COVERAGE1,15,16

The efficacy and safety of Litfulo was evaluated in a pivotal, randomised, double blind, placebo-controlled study in alopecia areata patients 12 years of age and older with ≥50% scalp hair loss. In the study group with Litfulo 50 mg (N=130) vs placebo (N=131), at Week 24, significantly more patients treated with Litfulo 50mg once daily achieved SALT score ≤10 (90% or more scalp hair coverage) vs placebo (estimated response rate 13.4% (n=17) vs 1.5% (n=2) respectively; treatment difference 11.9% [95% CI: 5.4–18.3]; p<0·0003) (primary outcome).1,15,16

Also at Week 24, significantly more patients treated with Litfulo 50mg once daily achieved SALT score ≤20 (80% or more scalp hair coverage) versus placebo (estimated response rate 23% (n=29) vs 1.6% (n=2) respectively; treatment difference 21.4% [95% CI: 13.4–29.5]; p<0.000001) (secondary outcome).1,15,17

Overall significance level (α) of 0.01.15

INCREASED SCALP HAIR COVERAGE1,10,11

The efficacy and safety of Litfulo was evaluated in a pivotal, randomised, double blind, placebo-controlled study in alopecia areata patients 12 years of age and older with ≥50% scalp hair loss including alopecia totalis and alopecia universali. In the study group with Litfulo 50 mg (N=130) vs placebo (N=131), at Week 24, significantly more patients treated with Litfulo 50mg once daily achieved SALT score ≤10 (90% or more scalp hair coverage) vs placebo (estimated response rate 13.4% (n=17) vs 1.5% (n=2) respectively (primary outcome).
Treatment difference 11.9% [95% CI: 5.4–18.3]; p=0·0003).1,2,3


Also at Week 24, significantly more patients treated with Litfulo 50mg once daily achieved SALT score ≤20 (80% or more scalp hair coverage) versus placebo (estimated response rate 23% (n=29) vs 1.6% (n=2) respectively (secondary outcome)
Treatment difference 21.4% [95% CI: 13.4–29.5]; p<0.000001).1,2,4

Data Limitations for Increased Scalp Hair Coverage:
Multiple imputation methods were based on generalised linear mixed model for longitudinal binary data up to Week 24, with an assumption of missing at random for SALT scores missing at Week 24 due to COVID-19. Patients with SALT scores missing due to other reasons were included in the analysis as non-responders. A single complete imputed data set for Week 24 was analysed using the Miettinen and Nurminen method.2,3,4
