New hope for HS sufferers: LAD191 enters Mid-Stage trial
NCT ID NCT07151937
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new injectable drug called LAD191 in 200 adults with moderate-to-severe hidradenitis suppurativa (HS), a painful skin condition causing abscesses and scarring. Participants will receive either LAD191, a placebo, or an active comparator (adalimumab) to see if LAD191 reduces skin lesions by at least 50% over 16 weeks. The goal is to find a more effective treatment for HS.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- LAD191 (injected under the skin)
- What this could lead to
- If successful, LAD191 could offer a new treatment option to reduce painful abscesses and nodules in people with hidradenitis suppurativa.
- What could go wrong
- This is an early Phase 2 study with only 200 participants. The drug may not work better than placebo, and side effects are still being evaluated.

Inclusion Criteria: * Aged greater than or equal to (\>=) 18 to less than or equal to (\<=) 65 years. * A diagnosis of moderate-to-severe HS defined as a total of \>= 5 inflammatory lesions (i.e., number of abscesses plus number of inflammatory nodules) at both the Screening and Baseline/Day 1 visits, with signs and symptoms of HS for at least 6 months. * HS lesions present in at least 2 distinct anatomic areas (e.g., left and right axilla), one of which must be at least Hurley Stage II or Hurley Stage III at both the Screening and Baseline/Day 1 visits. * History of inadequate response, intolerance, or contraindication to a course of a systemic antibiotics for treatment of HS at the screening visit. * Regular use of over-the-counter topical antiseptics on HS lesions and agrees to regular use, throughout the entirety of the study. * Participants who are women of child-bearing potential (WOBCP) and male participants must agree to the requirements for the avoidance of pregnancy and exposure of the participant's partner to LAD191 during the study. Exclusion Criteria: * HS with \>20 draining tunnels at the Screening or Baseline/Day 1 visit. * Ongoing medical conditions requiring systemic immunosuppressive/immunomodulating treatments during the study. * Known hypersensitivity to LAD191 or any of its excipients. * Known hypersensitivity to adalimumab or biosimilar or any of its excipients or meeting any warning or contraindication to adalimumab treatment as per the approved product information, and as per the Investigator's judgment. * Hypersensitivity or systemic reaction to a prior biologic (antibody-based) therapy, regardless of indication, that was clinically significant, as per the Investigator's judgment. * Prior treatment with LAD191. * Live or attenuated vaccinations 4 weeks prior to Baseline/Day 1 or is planning to receive any such vaccine during the study. * Pregnant or breastfeeding women, or women planning to become pregnant or breastfeed during the study. * Intention to use any concomitant medication or therapy that is not permitted by this protocol or failure to meet the required washout period for a particular prohibited medication prior to Baseline/Day 1.
