Brief summary

This is a multicenter, randomized, double-blinded, placebo-controlled clinical study of ORKA-002 in adult participants with moderate-to-severe HS.

Detailed description

The study will evaluate an induction dosing regimen of ORKA-002 administered every 4 weeks for 12 weeks compared with placebo during a double-blind induction period through Week 16. This will be followed by an open-label maintenance period, during which ORKA-002 will be administered every 12 weeks. The study will consist of four periods: * Screening Period * Induction Period (double-blind) * Maintenance Period (open-label) * Post-Treatment Follow-Up Period

Design outcomes

Primary

MeasureTime frameDescription
Proportion of participants achieving HiSCR75 at Week 16Week 16At least a 75% reduction from Baseline in the total abscess and inflammatory nodule count, with no increase from Baseline in abscess or draining tunnel count.

Secondary

MeasureTime frameDescription
Proportion of participants with a ≥ 3-point decrease from Baseline in the weekly mean of the HSSDD worst skin pain score at Week 16 among those with a Baseline score ≥ 3Week 16This endpoint assesses the proportion of participants who achieve at least a 3-point reduction in their weekly mean worst skin pain score by Week 16.
Proportion of participants achieving HiSCR50 at Week 16Week 16At least a 50% reduction from Baseline in the total abscess and inflammatory nodule count, with no increase from Baseline in abscess or draining tunnel count
Change from Baseline in the weekly mean of the Hidradenitis Suppurativa Symptom Daily Diary (HSSDD) worst skin pain score at Week 16Week 16This endpoint assesses the change from baseline to Week 16 in the average weekly patient-reported worst skin pain score, as recorded daily in the HSSDD.
Incidence of TEAEs, TESAEs, and TEAESIs and Observed values, potentially clinically important values, and change from baseline in vital signs, laboratory tests, and electrocardiogramsDay 1 through Week 92Incidence of Treatment-emergent Adverse Events (TEAEs), Treatment-emergent Serious Adverse events (TESAEs), and TEAEs of Special Interest (TEAESIs); These endpoints assess safety and tolerability of ORKA-002 in participants with moderate-to-severe HS.
