Is this trial a fit for you?

Likely a good fit

Adults with moderate-to-severe HS (≥6 months disease, ≥5 abscesses/inflammatory nodules, involvement of ≥2 body regions with at least one region Hurley II/III) who have had an inadequate response to at least one course of antibiotics and can comply with study visits and contraception requirements are ideal candidates.

Probably not a fit

Patients with very extensive disease such as more than 20 draining tunnels or active skin infections that would interfere with assessment are unlikely to benefit from or be eligible for this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with moderate-to-severe hidradenitis suppurativa will be assigned to receive one of two doses of NAV-240 or a matching placebo delivered by intravenous infusion and will be followed for 22 weeks with up to 9 clinic visits. The primary outcome is the proportion of participants achieving HiSCR75 (at least 75% reduction in abscess and inflammatory nodule count with no worsening of abscesses or draining tunnels) at Week 16. Participants will complete a daily pain diary and may remain on a stable regimen of certain oral antibiotics if required. Key eligibility includes disease duration ≥6 months, lesion count ≥5, involvement of at least two body regions with at least one region Hurley stage II or III, and prior inadequate response to at least one antibiotic.

Why it matters

Potential benefit: If successful, NAV-240 could help many patients achieve large reductions in inflamed lesions and reduce pain compared with placebo.

How similar studies have gone: NAV-240 is an investigational agent and prior data for this specific drug are limited, while established biologic therapies (for example anti-TNF agents) have demonstrated effectiveness in HS.
