Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

All participants may continue to receive stable background standard of care therapy for LN and systemic lupus erythematosus (SLE) as permitted by the protocol (for example, mycophenolate mofetil [MMF], azathioprine, antimalarials, glucocorticoids, cyclosporin, voclosporin, tacrolimus, angiotensin converting enzyme [ACE] inhibitors, angiotensin receptor blockers [ARBs]).

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Key Inclusion Criteria:

  • Participants who have a diagnosis of SLE according to European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) 2019 Criteria
  • Has a history of International Society of Nephrology/Renal Pathology Society (ISN/RPS) Class III or IV with or without Class V glomerulonephritis on renal biopsy within 24 months prior to screening or as performed during screening.
  • Has proteinuria level between ≥0.5 to 3.0 grams (g)/g/day assessed via urine protein to creatine ratio (UPCR) during screening.
  • Has evidence of classical complement activation at screening
  • Has a history of receiving one or more standard therapies for LN

Key Exclusion Criteria:

  • Has a history of ISN/RPS Class VI or isolated Class V (without co-existent/predominant Class III or IV glomerulonephritis) glomerulonephritis on renal biopsy.
  • Has severe kidney disease defined as eGFR of <30 milliliters (mL)/minute/1.73 square meter (m^2) or end-stage renal disease (ESRD) requiring dialysis or kidney transplantation.
  • Has a concurrent systemic autoimmune disease that may confound study assessments other than SLE, LN, or cutaneous lupus erythematosus.

NOTE: Other inclusion and/or exclusion criteria may apply.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: Baseline (Week 1) up to Week 15
Baseline (Week 1) up to Week 15

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Change From Baseline in Free Complement Component 1q (C1q) Concentrations in Serum Over Time
Time Frame: Baseline (Week 1), up to Day 31
Baseline (Week 1), up to Day 31
