A Study of Enpatoran in Participants With Cutaneous Manifestations of Lupus With or Without Systemic Disease

A Phase 3, Randomized, Double-Blind,Placebo-Controlled Parallel Study to Evaluate the Efficacy and Safety of Enpatoran in Participants With Active Cutaneous Manifestations of Lupus Erythematosus With or Without Systemic Disease Receiving Standard of Care (ELOWEN-1)

A Study of Enpatoran in Participants With Cutaneous Manifestations of Lupus With or Without Systemic Disease (NCT07332481) is a Phase 3 interventional studying Systemic Lupus Erythematosus (SLE) and Cutaneous Lupus Erythematosus (CLE), sponsored by EMD Serono Research & Development Institute, Inc.. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

The purpose of this global, multicenter, Phase 3 study is to evaluate the efficacy and safety of enpatoran over 24 weeks in participants with active cutaneous manifestations of lupus erythematosus with or without systemic disease. Study details include: Study Duration: Up to 35 weeks. Treatment Duration: 24 weeks. Visit Frequency: every 4 weeks, with the exception of the Week 2 televisit. Study Intervention Name: Enpatoran, Placebo. Intervention Form: Film-coated tablet.

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Systemic Lupus Erythematosus (SLE), Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 202 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Systemic Lupus Erythematosus (SLE) subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Inclusion Criteria - Vaccinations are up to date according to local guidelines/recommendations. Recombinant zoster vaccination is encouraged but not mandatory. - Participants with diagnosis of Discoid Lupus Erythematosus (DLE) and/or Subacute Cutaneous Lupus Erythematosus (SCLE) documented in medical history, with or without Systemic Lupus Erythematosus (SLE). - Participants with active Acute Cutaneous Lupus Erythematosus (ACLE) as sole cutaneous manifestations is allowed in the presence of SLE and should be present for at least 6 weeks prior to the Screening visit. - Participants with diagnosis of SLE fulfilling the European Alliance of Associations for Rheumatology (EULAR)/American College of Rheumatology (ACR) 2019 classification criteria, must have active DLE and/or SCLE and/or ACLE. For participants with SLE: - Participants with diagnosis of SLE and fulfill EULAR/ACR 2019 classification criteria. - Participants with disease duration (cutaneous disease and, where applicable, SLE) of \>= 6 months from time of diagnosis to Screening. - Participants with CLASI-A score \>= 8 at Screening and Day 1 visits. - Other protocol-defined inclusion criteria may apply. Exclusion Criteria - Participants with primary diagnosis of autoimmune rheumatic disease (e.g., systemic sclerosis, rheumatoid arthritis) other than Cutaneous Lupus Erythematosus (CLE) and SLE. - Participants with any condition including dermatological diseases other than cutaneous manifestations of lupus (e.g. psoriasis), any uncontrolled disease (e.g. asthma, chronic obstructive pulmonary disease, interstitial lung disease, bronchiectasis, pulmonary arterial hypertension), or life-threatening manifestations of lupus (e.g. active systemic vasculitis) that in Investigator's or Sponsor/designee's opinion constitutes inappropriate risk or contraindication for participation. - Participants with drug-induced lupus (SLE or CLE). ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.
