Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 70 years
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Patients with 6 or more months of SLE according to the 2019 EULAR/ACR criteria, have positive autoantibodies or low complement at screening, and have active SLE as measured by SLEDAI-2K of 6 or more, or 4 or more if joint involvement is present.
- Patients need to be on treatment which can be:
- A stable dose of oral corticosteroid (≤40 mg/day prednisone or equivalent) for a minimum of 2 weeks prior to signing of the informed consent form (ICF) at the Screening Visit. The dose of oral corticosteroid the patient is taking should not increase between screening and Week 0 (Day 1).
- And/or antimalarial treatment (e.g., hydroxychloroquine, chloroquine, quinacrine),
- And/or no more than 1 of the following conventional DMARDS:
- Azathioprine ≤200 mg/day
- Mycophenolate mofetil ≤2 g/day or mycophenolic acid ≤1.44 g/day
- Oral, subcutaneous, or intramuscular (IM) methotrexate ≤20 mg/week.
Who cannot join
- Drug-induced SLE or other autoimmune diseases that, in the opinion of the Investigator, are likely to confound efficacy assessments
- Active, proliferative lupus nephritis that in the Investigator's opinion may require treatment not allowed by the protocol
- Current disease other than SLE that, in the opinion of the Investigator, is likely to interfere with SLE disease activity assessments. Examples include severe fibromyalgia, severe osteoarthritis and severe cardiorespiratory diseases.
- Active severe or unstable neuropsychiatric SLE including, but not limited to the following: aseptic meningitis; cerebral vasculitis; myelopathy; demyelination syndromes (ascending or transverse myelitis, acute inflammatory demyelinating polyradiculopathy); acute confusional state; impaired level of consciousness; psychosis; acute stroke or stroke syndrome; cranial neuropathy; new seizures; cerebellar ataxia; and mononeuritis multiplex.
- That would make the patient unable to fully understand the ICF, or
- Where, in the opinion of the Principal Investigator, protocol-specified SOC is insufficient and utilization of a more aggressive therapeutic approach not permitted in the protocol, is indicated

What is being measured
The primary outcome is the main question the study is designed to answer.
To compare the effect on disease activity measured by the proportion of patients achieving British Isles Lupus Assessment Group (BILAG)-based Composite Lupus Assessment (BICLA) response at Week 48 between doses of ESK-001 and placebo
Measured: Week 48
Secondary outcomes (14)
To assess the safety and tolerability of multiple dose levels of ESK-001
Safety and Tolerability will be assessed with clinical and laboratory assessments including blood tests for liver and kidney function, ECGs, hematological measures and physical examinations throughout the time of the study and safety follow up. The number and proportion of TEAEs, SAEs, AEs of greater than grade 3 severity and AEs of Clinical Interest will be recorded.
Measured: Week 48
To compare the effect on disease activity measured by the proportion of patients achieving an SLE Responder Index of ≥4 (SRI[4]) response at Week 48
Measured: Week 48
To compare corticosteroid use in patients at Week 48
To compare the number and percentage of patients using corticosteroids and continuous summaries of dose used will be assessed as well as the frequency and percentage of patients able to taper corticosteroids and maintain low doses following taper.
Measured: Week 48
To compare the effect on cutaneous disease activity measured by the proportion of patients with a CLASI activity score of ≥8 at baseline achieving ≥ 50% reduction in the CLASI activity score at Week 48 between doses of ESK-001 and placebo
Measured: Week 48
To compare the effect on disease activity measured by the proportion of patients achieving BICLA responses at Week 48 between doses of ESK-001 and placebo by stratification groups
Measured: Week 48
To compare the Lupus Low Disease Activity State (LLDAS) response between doses of ESK-001 and placebo at Week 48
Measured: Week 48
To compare the annualized flare rate through Week 48
Measured: Week 48
To use the SF-36 (Short Form-36 item QoL measure) to compare the effect on health-related quality of life (HRQOL) between doses of ESK-001 and placebo
Efficacy: Comparing the effects of Esk-001 doses vs Placebo on Patient Reported Outcome (PRO) as it relates to Health-Related Quality of Life (HRQoL) as measured by self-reporting using the SF-36 (Short Form-36 item QoL measure) Questionnaire which uses a scale of 0 to 100. The higher numbers mean better health.
Measured: Week 48
To use the SLE-specific Lupus Quality of Life (LQoL) questionnaire to compare the effect on health-related quality of life (HRQOL) between doses of ESK-001 and placebo
Efficacy: Comparing the effects of Esk-001 doses vs Placebo on Patient Reported Outcome (PRO) as it relates to Health-Related Quality of Life (HRQoL) as measured by self-reporting using the SLE-specific Lupus Quality of Life (LQoL) questionnaire which uses a scale of 0 to 100. The higher numbers mean better health.
Measured: Week 48
To compare disease-specific QoL between doses of ESK-001 and placebo
Efficacy: To compare disease-specific QoL between doses of ESK-001 and placebo using the SLE Disease Activity Index 2000 (SLEDAI2K) measured on a scale of 0 to 105 where the higher numbers mean more disease activity.
Measured: Week 48
To compare disease-specific QoL between doses of ESK-001 and placebo
Efficacy: To compare disease-specific QoL between doses of ESK-001 and placebo using the British Isle Lupus Assessment Group 2004 (BILAG-2004) with a scale of A to E (A meaning very active disease and E no current or previous disease).
Measured: Week 48
To compare disease-specific QoL between doses of ESK-001 and placebo
Efficacy: To compare disease-specific QoL between doses of ESK-001 and placebo using the Physician's Global Assessment (PGA) evaluating disease response using the 4-point VAS (Visual Analog Scale) of 0 to 3 (0 means no flares and 3 means severe flare in disease).
Measured: Week 48
To compare Fatigue measured by FACIT-F between doses of ESK-001 and placebo
To compare patient-reported fatigue as measured by Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire between doses of ESK-001 and placebo, where the score range is 0 to 52 and a lower score indicates greater fatigue/worse outcome.
Measured: Week 48
To compare patient global assessment of disease activity (PtGA) between doses of ESK-001 and placebo
Efficacy: To compare disease-specific QoL between doses of ESK-001 and placebo using the PtGA (Patient Global Assessment) instrument. Patients record on a visual analog scale (VAS) how well or badly they feel as a result of the disease in their own estimation over the course of the study.
Measured: Week 48

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 21 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 169 sites in United States, India, Mexico, Poland, Argentina and 16 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To compare the effect on disease activity measured by the proportion of patients achieving British Isles Lupus Assessment Group (BILAG)-based Composite Lupus Assessment (BICLA) response at Week 48 between doses of ESK-001 and placebo (time frame: Week 48). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
