Study to Evaluate Tulisokibart for Hidradenitis Suppurativa (MK-7240-012)

Phase 2
Recruiting
Conditions
Hidradenitis Suppurativa
Interventions
Drug: Placebo
Registration Number
NCT06956235
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This is a phase 2b randomized, double-blind, placebo-controlled study of the safety and efficacy of tulisokibart in participants with moderate to severe hidradenitis suppurativa. The primary hypothesis is that at least 1 dose of tulisokibart is superior to placebo with respect to the proportion of participants achieving a 50% reduction in Hidradenitis Suppurativa Clinical Response (HiSCR50) at Week 16 (ie, at end of double-blind treatment).

Detailed Description

This study consists of a 16-week Double-blind Period and a 100-week Long-term Extension (LTE) composed of a 40-week Main Extension and a 60-week Optional Extension.

Inclusion Criteria
  • Has signs and symptoms of hidradenitis suppurativa (HS) for ≥ 6 months and a clinical diagnosis of HS at screening
  • Has moderate or severe HS

Exclusion Criteria
  • Has other active skin conditions that may interfere with the assessment of HS
  • Has any immune-mediated inflammatory condition that is not well controlled and which may potentially require biologic therapy

Primary Outcome Measures
NameTimeMethod
Percentage of participants achieving Hidradenitis Suppurativa Clinical Response (HiSCR) 50 at Week 16Week 16

The percentage of participants with ≥50% reduction in total abscesses and inflammatory nodules (AN) count with no increase in abscess count, and no increase in draining tunnels (ie, HiSCR50) will be reported.

Secondary Outcome Measures
NameTimeMethod
Percentage of participants achieving HiSCR75 at Week 16Week 16

The percentage of participants with ≥75% reduction in total abscesses and inflammatory nodules (AN) count with no increase in abscess count, and no increase in draining tunnels (ie, HiSCR75) will be reported.

Mean Change from Baseline in Dermatology Life Quality Index (DLQI) at Week 16Week 16

The DLQI is a validated dermatology-specific instrument that measures the HRQoL in adult patients with skin diseases. The DLQI consists of 10 questions and provides a total HRQoL score, as well as scores for 6 aspects of QoL: symptoms and feelings; daily activities; leisure; work/school; personal relationships; and treatment. The recall period is over the last week. Question responses are assessed using a 4-point Likert rating scale ranging from "not at all" (scored 0) to "very much" (scored 3). The final score ranges from 0 (no impact on QOL) to 30 (maximum impairment). The mean change from baseline in DLQI at Week 16 will be reported.

Percentage of Participants Who Experience One or More Adverse Events (AEs)Up to ~130 weeks

An AE is defined as any untoward medical occurrence in a participant administered a study treatment which did not necessarily have to have a causal relationship with this treatment. An AE could be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of study treatment, is also an AE. The percentage of participants with any AE will be reported.

Percentage of Participants Who Discontinue Study Intervention Due to an AEUp to ~116 weeks

An AE is defined as any untoward medical occurrence in a participant administered a study treatment which did not necessarily have to have a causal relationship with this treatment. An AE could be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition that is temporally associated with the use of study treatment, is also an AE. The percentage of participants discontinuing from study intervention due to AE will be reported.
