Overview of the studies
These records describe Phase 3 clinical trials that are studying SALICYLIC ACID in people with hidradenitis suppurativa (HS).[1][2] Both trials are interventional, which means the researchers give a study treatment and then measure the results.[1][2] The studies are authorised and are focused on patients with moderate to severe disease.[1][2]
Who can participate
The target population in both trials is adult and adolescent patients with moderate to severe HS.[1][2] This means the studies are not for every person with HS, but for those who meet the trial rules and have a more serious form of the disease.[1][2]
One trial plans to enroll 532 participants, and the other plans to enroll 487 participants.[1][2] These are fairly large studies, which is common in Phase 3 research.[1][2]
What is being measured
The main endpoint in both trials is HiSCR50 at Week 16.[1][2] HiSCR50 is a study measure used in HS research and means at least a 50% decrease in the number of abscesses and inflammatory nodules, with no increase in abscesses or draining tunnels/fistulae compared with the start of the study.[1][2]
The brief study aim is to show the efficacy of the treatment compared with placebo after 16 weeks of treatment.[1][2] In patient-friendly language, the researchers want to see whether the study treatment helps skin lesions improve more than a placebo, which is a look-alike treatment with no active study drug.[1][2]
Study design and phase
Both records describe Phase 3 studies.[1][2] Phase 3 trials usually test whether a treatment works in a larger group of patients and continue to look closely at safety and tolerability.[1][2]
The trial titles and intervention lists mention remibrutinib, LOU064, placebo to remibrutinib (LOU064), clindamycin, and triamcinolone.[1][2] The source data also shows that the studies compare the active treatment with placebo and include other listed study medicines or procedures as part of the trial design.[1][2]
Trial details
The first study, 2024-513266-19-00, is an authorised Phase 3 trial with 532 planned participants.[1] Its primary outcome is HiSCR50 at Week 16.[1]
The second study, NCT06799000, is also an authorised Phase 3 trial with 487 planned participants.[2] It uses the same main endpoint, HiSCR50 at Week 16, and has the same overall goal of comparing efficacy with placebo after 16 weeks.[2]
Important patient terms
- Placebo: a look-alike treatment used for comparison. It helps researchers see whether the study treatment works better than no active treatment.[1][2]
- Baseline: the starting point before treatment begins. Trial results are often compared with this first measurement.[1][2]
- Abscess and inflammatory nodule count: the number of painful skin lumps and pus-filled areas counted by the researchers.[1][2]
- Draining tunnels/fistulae: channels under the skin that can leak fluid. The endpoint checks that these do not increase.[1][2]
- Tolerability: how well patients can handle the treatment during the study.[1][2]
