Adalimumab is the only FDA- and EMA-approved treatment for moderate-to-severe hidradenitis suppurativa (HS), suggesting that the mechanism of action of adalimumab is distinct in HS and may contribute to improved wound healing. We have demonstrated that adalimumab, but neither etanercept nor certolizumab-pegol, induces a wound healing profile in vitro, which may underlie the differences in efficacy between various anti-TNF agents. To examine and compare the efficacy of therapeutic TNF inhibitors in chronic cutaneous wound healing in vivo, a human TNF knock-in Leprdb/db mouse model was established. The vehicle group exhibited severe impairments in cutaneous wound healing. In contrast, adalimumab significantly accelerated healing, confirmed by both histologic assessment and a unique healing transcriptional profile. Moreover, adalimumab and infliximab showed similar levels of efficacy, but golimumab was less effective, along with etanercept and certolizumab-pegol. In line with histologic assessments, proteomics analyses from healing wounds exposed to various TNF inhibitors revealed distinct and differential wound healing signatures that may underlie the differential efficacy of therapeutic inhibitors in accelerating chronic wound healing.
