Investigational drugs in clinical trials for Hidradenitis Suppurativa.

INTRODUCTION: Hidradenitis suppurativa is a chronic skin disease with a significant unmet need for treatment options. Randomized controlled trials are few and only a single drug (adalimumab) has Hidradenitis as a registered indication. AREAS COVERED: The clinicaltrials.gov and the EudraCT clinical trials register for reported trials on Hidradenitis Suppurativa was searched on the 22-06-2017. Trials for upcoming new drugs for HS are reported focusing on drugs in phase I and II trials.The clinicaltrials.gov and the EudraCT clinical trials register for reported trials on Hidradenitis Suppurativa was searched on the 22-06-2017. Trials for upcoming new drugs for HS are reported focusing on drugs in phase I and II trials. EXPERT OPINION: Currently, MABp1, Secukinumab, CJM112, Apremilast and IFX-1 are being investigated in Phase I and II trials and offer theoretical and promising new treatment options. A trial with the drug MEDI8968 has been terminated with disappointing results. Metformin, Botulinum Toxin B, Provodine, Benzoyl Peroxide and intralesional triamcinolone are being tested as well. Treatment of Hidradenitis remains a challenge and quality RTCs are needed. Studies indicates a range of potential targets for therapy such as interleukin-1 and interleukin-17, but 'broad-spectrum' immunosuppressants like phosphodiesterase-4 inhibitors are being examined as well. A range of outcomes, including Physician Global Assessment, Sartorius scores and hidradenitis suppurativa clinical response are used in these trials, making future meta-analysis of the data difficult.
