Multicenter Study
Twenty-four-week interim analysis from a phase 3 open-label trial of adalimumab in Japanese patients with moderate to severe hidradenitis suppurativa.
Hidradenitis suppurativa (HS) is a chronic skin disease characterized by recurrent painful inflamed nodules/abscesses and draining fistulas that negatively impact quality of life. Adalimumab, a monoclonal antibody against tumor necrosis factor-α, has been approved in the EU, USA and Japan for the treatment of moderate to severe HS. This is an interim analysis of an ongoing phase 3, multicenter, open-label, single-arm study of the safety and efficacy of adalimumab weekly dosing in Japanese patients with moderate to severe HS. ⋯ At week 12, 86.7% of patients achieved clinical response, with improvements at week 12 across the primary and secondary end points generally sustained through week 24. Adalimumab weekly dosing was generally safe and well tolerated with no new safety findings through week 24. These results suggest that adalimumab is effective and well tolerated in Japanese patients with moderate to severe HS.
