A Study to Test Long-term Treatment With Spesolimab in People With a Skin Condition Disease Called Hidradenitis Suppurativa (HS) Who Took Part in a Previous Study With Spesolimab

May 21, 2026 updated by: Boehringer Ingelheim

Lunsayil LTE: An Extension Trial Assessing Long-term Spesolimab Treatment in Patients With Hidradenitis Suppurativa (HS)

This study is open to people with hidradenitis suppurativa (HS) who have completed another study with spesolimab (study 1368-0098 (NCT05819398) or study 1368-0100).

The purpose of this study is to find out how well people tolerate spesolimab and whether it helps people with HS in the long-term. For about 1.5 years, participants get spesolimab injections under the skin every 2 weeks.

Participants are in the study for about 2 years. During this time, participants have 41 visits. 24 visits are done at the study site. 17 visits can be done by video call at the participant's home. At study visits, doctors check the severity of the participant's HS and collect information on any health problems of the participants.

Description

Inclusion Criteria:

  1. Signed and dated written informed consent in accordance with ICH Harmonized Guideline for Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Spesolimab low dose
Participants with hidradenitis suppurativa who completed their treatment with spesolimab in Part 1 of trial 1368-0098 and who met the eligibility criteria for this extension trial. Participants continued on the same dosing regimen that they had in the parent trial. Spesolimab was administered every 2 weeks with a subcutaneous injection. To keep the study blinded, participants were additionally administered placebo to match the volume administered to the participants in the high dose group. Patients were planned to be treated for 76 weeks, followed by a 16-week safety follow-up period.
Administered every 2 weeks with a subcutaneous injection.
Administered every 2 weeks with a subcutaneous injection.
Experimental: Spesolimab high dose
Participants with hidradenitis suppurativa who completed their treatment with spesolimab in Part 1 of trial 1368-0098 and who met the eligibility criteria for this extension trial. Participants continued on the same dosing regimen that they had in the parent trial. Spesolimab was administered every 2 weeks with a subcutaneous injection. Patients were planned to be treated for 76 weeks, followed by a 16-week safety follow-up period.
Administered every 2 weeks with a subcutaneous injection.
Experimental: Spesolimab high dose with prior placebo
Participants with hidradenitis suppurativa who completed their treatment with placebo in Part 1 of trial 1368-0098 and who met the eligibility criteria for this extension trial. Participants continued on the same dosing regimen that they had in the parent trial. Spesolimab was administered every 2 weeks with a subcutaneous injection. Patients were planned to be treated for 76 weeks, followed by a 16-week safety follow-up period.
Administered every 2 weeks with a subcutaneous injection.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Occurrence of Treatment Emergent Adverse Events (TEAE) up to the End of Maintenance Treatment Period
Time Frame: From first drug administration, up to 16 weeks after last administration, up to 39 weeks.
The occurrence of treatment emergent adverse events (TEAEs) is reported as the number of patients with TEAEs. TEAEs were defined as all adverse events occurring between start of treatment in the extension trial and the end of its residual effect period. Adverse events that start before first drug intake in the extension trial and deteriorate under treatment during the extension trial were also considered as 'treatment-emergent'.
From first drug administration, up to 16 weeks after last administration, up to 39 weeks.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

NO

IPD Plan Description

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).

https://www.clinicalstudies.boehringer-ingelheim.com/msw/datasharing

IPD Sharing Time Frame

One year after the approval has been granted by major Regulatory Authorities and after the primary manuscript has been accepted for publication, or after termination of the development program.

IPD Sharing Access Criteria

For study documents upon signing of a 'Document Sharing Agreement'. For study data 1. after the submission and approval of the research proposal (checks will be performed by the sponsor and/or the independent review panel, including checking that the planned analysis does not compete with sponsor's publication plan); 2. and upon signing of a legal agreement.
