Background

Effective anti-inflammatory treatments for hidradenitis suppurativa (HS) are limited.

Objective

To evaluate the efficacy and short-term safety of apremilast in patients with moderate HS.

Methods

A total of 20 patients with moderate HS were randomized in a 3:1 ratio to receive blinded treatment with apremilast, 30 mg twice daily, or placebo for 16 weeks. The primary outcome was the Hidradenitis Suppurativa Clinical Response at week 16. Linear mixed effects modeling (analysis of covariance) was used to assess secondary clinical outcomes between treatment groups.

Results

The HS clinical response was met in 8 of 15 patients in the apremilast group (53.3%) and none of 5 patients in the placebo group (0%) (P = .055) at week 16. Moreover, the apremilast-treated patients showed a significantly lower abscess and nodule count (mean difference, –2.6; 95% confidence interval, –6.0 to –0.9; P = .011), NRS for pain (mean difference, –2.7; 95% –4.5 to –0.9; P = .009), and itch (mean difference, –2.8; 95% confidence interval, –5.0 to –0.6; P = .015) over 16 weeks compared with the placebo-treated patients. There was no significant difference in the Dermatology Life Quality Index over time between the 2 treatment groups (mean difference, –3.4; 95% confidence interval, –9.0 to 2.3; P = .230). The most frequently reported adverse events in the apremilast-treated patients were mild-to-moderate headache and gastrointestinal symptoms, which did not result in dropouts.

Limitations

Small number of patients, relatively short study duration.

Conclusion

Apremilast, at a dose of 30 mg twice daily, demonstrated clinically meaningful efficacy and was generally well tolerated in patients with moderate HS.

Patients

Patients who were at least 18 years of age with moderate HS, defined as a HS-PGA score of 3, were enrolled. Additionally, patients were required to have at least 4 inflammatory lesions (ie, abscesses, draining sinuses/tunnels, or inflammatory nodules in at least 2 anatomic locations). Patients receiving systemic antibiotics or immunosuppressive/immunomodulating therapy were required to stop treatment at least 28 days before baseline and until the end of study. Patients were excluded if they had

Patients

Enrollment occurred between February and August 2017, and a 16-week follow-up was completed in December 2017. In total, 21 patients were randomized, of whom 20 received at least 1 dose of study medication and were included in the intention-to-treat population. Of these, 18 (90%) completed the week 16 follow-up visit (Fig 1). Of the 15 patients receiving apremilast, 2 (13%) discontinued the study: 1 patient discontinued between week 4 and week 8 because of personal circumstances (travel distance

Discussion

The main finding from this study was a clinically meaningful improvement of moderate HS after treatment with apremilast at a dose of 30 mg twice per day for 16 weeks. Apremilast significantly decreased disease activity as measured by the AN count, and 53.3% of patients receiving apremilast achieved the HiSCR in comparison with none of the patients receiving placebo. In addition, apremilast for 16 weeks was well tolerated by patients with moderate HS. According to the study protocol, the
