Trial Summary

What is the purpose of this trial?

This trial is testing a new medication called ESK-001 to see if it can help adults with SLE, a chronic autoimmune disease. The study will check the effectiveness and safety of ESK-001 over several months.

Will I have to stop taking my current medications?

The trial requires that you stay on a stable dose of certain medications, like oral corticosteroids, antimalarials, or specific DMARDs (disease-modifying antirheumatic drugs), before and during the study. You should not increase the dose of these medications between screening and the start of the trial.

What safety data exists for ESK-001 or similar treatments in humans?

The study on a similar treatment, GSK2586184, for lupus found safety concerns, including elevated liver enzymes and a serious drug reaction in some patients, leading to the study's early termination. ^{1 2 3 4 5}

Eligibility Criteria

Adults with active Systemic Lupus Erythematosus (SLE) for at least 6 months, meeting specific disease criteria and on stable medications like Azathioprine or Methotrexate. Excluded are those with chronic infections, other autoimmune diseases that could affect results, recent use of oral anti-infectives, severe unrelated conditions, or a history of significant neuropsychiatric SLE.

Inclusion Criteria

I've been on a stable dose of corticosteroids (≤40 mg/day) for at least 2 weeks.

I have had lupus for over 6 months, with active symptoms and positive tests.

I take 200 mg or less of Azathioprine daily.

Exclusion Criteria

I have had a severe herpes infection before.

I haven't had a serious infection except for nail fungus in the last 8 weeks.

I haven't been hospitalized or needed IV antibiotics for an infection in the last 4 weeks.

Treatment Details

Interventions

• ESK-001 (Monoclonal Antibodies)
• Placebo (Placebo)

Trial Overview The trial is testing the effectiveness and safety of multiple doses of a new drug called ESK-001 against a placebo in adults with SLE. It will compare how well each treatment works and monitor any changes in the disease's activity and severity.

Findings from Research

The JAK1 inhibitor GSK2586184 was evaluated in a study involving 50 adults with systemic lupus erythematosus (SLE) over 12 weeks, but it showed no significant effect on interferon transcriptional biomarkers, leading to the study being declared futile.

Safety concerns arose during the trial, including elevated liver enzymes in six patients, which resulted in immediate cessation of dosing and indicated that GSK2586184 is not suitable for further evaluation in SLE patients.

In a 36-week phase IIb trial involving 185 adults with active systemic lupus erythematosus, the immunotherapeutic vaccine interferon-α kinoid (IFN-K) successfully induced neutralising antibodies in 91% of patients and significantly reduced the interferon gene signature, indicating its potential efficacy.

While the primary clinical endpoint was not met, IFN-K showed significant benefits in secondary outcomes, including a higher rate of achieving lupus low disease activity state (53% vs 30%) and a notable reduction in corticosteroid use, suggesting a favorable safety profile.

In a study of 38 Portuguese patients with Systemic Lupus Erythematosus (SLE), belimumab demonstrated significant effectiveness, with SLE Responder Index (SRI) response rates increasing from 51.9% at 6 months to 91.7% at 24 months, indicating a reduction in disease activity.

Belimumab was associated with a good safety profile, with only five patients experiencing adverse events, primarily infections, and the treatment led to a significant decrease in disease activity markers and daily steroid use.
