Immunosuppressant medications include azathioprine up to 2 mg/kg, methotrexate up to 20 mg/week, mycophenolate mofetil up to 3000 mg/day or mycophenolic acid <= 2.16 g/day. The subject will be taken off these immunosuppressant medications 2 weeks prior to administration of study medication and will be kept off these medications for the duration of study. Any subject experiencing worsening of SLE disease activity will be treated by a single dose of intra-muscular corticosteroid. This will be allowed only once during each period of the study. A second flare during each period requiring treatment would lead to withdrawal of the subject. The subjects in comparator group will continue on standard of care treatment.

About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Phase Ib Study to Evaluate the Safety, Tolerability, And Pharmacokinetics of Gusacitinib in Subjects With Systemic Lupus Erythematosus (SLE)

Background:

Systemic lupus erythematosus (SLE), also called lupus, is a disease that causes the body s immune system to attack healthy tissue. Lupus causes swelling and inflammation in the skin, skin, joints, kidneys, brain, blood vessels, and other organs. There is no cure for lupus. Current treatments do not help everyone and may have adverse effects. Better treatments are needed.

Objective:

To test a study drug (Gusacitinib) in people with lupus.

Eligibility:

People aged 18 years and older with lupus.

Design:

Participants will be screened. They will have a physical exam with blood and urine tests and a test of their heart function. They will have a chest X-ray. They will have tests that use blood pressure cuffs to measure blood flow and pressure throughout the body.

Participants will have 9 clinic visits and 6 phone visits over about 7 months.

The study has 3 parts.

Part 1: Gusacitinib is a tablet taken by mouth. Participants will be divided into 3 groups. One group will receive the study drug, and a second group will get a placebo. The placebo looks like the study drug but does not contain any medicine. Both of these groups will take their tablets once a day for 12 weeks. The third group will continue to take their usual medications for lupus throughout the study.

Part 2: All participants who took the study drug or placebo in part 1 will take the study drug once a day for 12 weeks.

Part 3: All participants who took the study drug will stop taking it for 4 weeks.

Read the detailed description

STUDY DESCRIPTION:

This is a phase Ib study of Gusacitinib a dual inhibitor of JAK and SYK kinases, that can simultaneously target multiple signaling pathways responsible for the SLE disease pathogenesis. This study will compare the safety of Gusacitinib 80 mg with placebo initially in a double-blind period and then 80 mg daily in an open label period, followed by an off-drug period.

In addition, we will have a comparator group of SLE subjects receiving standard of care treatment. We hypothesize that Gusacitinib will be safe and well tolerated in subjects with SLE.

OBJECTIVES:

Primary Objective: The primary Objective of the study is to determine safety and tolerability of Gusacitinib 80 mg in subjects with SLE.

Secondary Objectives: Pharmacokinetics of Gusacitinib in SLE. Effects of Gusacitinib on plasma lipid profile, vascular stiffness, and endothelial dysfunction. Efficacy of Gusacitinib in controlling SLE disease activity. Exploratory objectives to understand the effects of dual JAK and SYK inhibition on Interferon Gene Signature, Serum Cytokines, NET formation, and Immune cells phenotype.

ENDPOINTS:

Primary Endpoint: Adverse Events severity (as defined by AEs equal or greater than grade 3 as per the National Cancer Institute (NCI), Common Terminology Criteria for Adverse Events (CTCAE) v5.0) and frequency as compared to placebo at week 12.

Secondary Endpoints: Change in the proportion of patients achieving SLE Responder Index-4 (SRI 4) response at week 24 compared to baseline. Another efficacy analysis will be done by comparing subjects treated with Gusacitinib vs. placebo at week 12. SRI-4 response is defined as:

  • Reduction of >=4 points from baseline in SLEDAI-2K score
  • No new BILAG A or no more than 1 new BILAG B disease activity scores
  • No worsening (defined as an increase of >=0.3 points [10 mm] from baseline) in the Physician s Global Assessment of Disease Activity
  • Change in SLEDAI-2K total score at week 24

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Gusacitinib in people with Systemic Lupus Erythematosus, run by National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) at 1 site in United States.

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 18 inclusion and 30 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: withdrawn, as of the sponsor's last update on 13 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Adverse Events severity (as defined by AEs equal or greater than grade 3 as per the National Cancer Institute (NCI), Common Terminology Criteria for Adverse Events (CTCAE) v5.0) and frequency as compared to placebo at week 12 (time frame: Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06238531.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2025.
