Pre-emptive Treatments in Lupus Nephritis Patients With Serological Reactivation

December 13, 2024 updated by: The University of Hong Kong

Pre-emptive Increase of Immunosuppressive Treatments in Lupus Nephritis Patients With Asymptomatic Serological Reactivation

The optimal management of asymptomatic serological reactivation (ASR) in lupus nephritis (LN) patients remained undefined. This project aims to investigate the impact of pre-emptive treatment on disease relapse in LN patients who experienced ASR.

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

LN patients who presented with ASR [defined as 1) increase in anti-dsDNA >100 IU/mL , with or without drop in serum complement; or 2) increase in anti-dsDNA to higher than the normal range and >2 times of the preceding value, with or without drop in serum complement; and 3) Absence of renal or systemic manifestations of SLE) will be randomized to receive pre-emptive increase in immunosuppression or had their current immunosuppressive therapies unchanged.

Patients will be followed at 4-, 12-, 24-wk and then every 12 weeks up to 24 months to monitor for renal or extra-renal relapses. Bloods and urine will be collected for measurement of renal and serological parameters, and also B cell signatures.

Primary outcomes: Renal Flare (denoted as proteinuria >1g/D; presence of urinary RBC >30 hpf/RBC casts, or increase in SCr >15% and positive anti-dsDNA)

Secondary outcomes:

  • Safety & tolerability of pre-emptive increase of immunosuppressive treatments
  • Extra-renal flares
  • Renal function at 24 months
  • Changes in serological parameters

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 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients with biopsy-proven lupus nephritis who experienced an episode of Asymptomatic Serological Flare (ASF) as defined by:

    1. Increase in anti-dsDNA to >100 IU/mL, with or without drop in serum complement levels OR

    2. Increase in anti-dsDNA to higher than the normal range and more than two times of the preceding value, with or without drop in serum complement levels

      AND

    3. Absence of renal or systemic manifestation of SLE.

Exclusion Criteria:

  1. Patients who cannot provide informed consent.
  2. Patients whom the clinicians opined to have excessively high risk of infection or malignancy.
  3. Patients who are pregnant or lactating.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Pre-emptive Treatment (Prednisolone and/or AZA/MMF)
  1. Increase prednisolone to 0.4-0.5 mg/kg/day; taper by 5 mg every 2 weeks to reach 15mg/day; then further reduce by 2.5 mg every 2 week and aim to reach 5-7.5 mg/day after 12 weeks.

  2. Adjustment of the 2nd agent would be as follows:

    1. For patients who receive AZA <75mg/day; increase the dose of AZA to 75 mg/day.
    2. For patients who receive MMF <1g/day, increase the dose of MMF to 1g/day.
Procedure: Pre-emptive increase of immunosuppressive treatments
  1. Increase prednisolone to 0.4-0.5 mg/kg/day; taper by 5 mg every 2 weeks to reach 15mg/day; then further reduce by 2.5 mg every 2 week and aim to reach 5-7.5 mg/day after 12 weeks.

  2. Adjustment of the 2nd agent would be as follows:

    1. For patients who receive AZA <75mg/day; increase the dose of AZA to 75 mg/day.
    2. For patients who receive MMF <1g/day, increase the dose of MMF to 1g/day.
Drug: Prednisolone and/or AZA/MMF
Prednisolone and/or AZA/MMF
No Intervention: Control
Current immunosuppressive regimen and dosage should remain unchanged until the development of renal or extra-renal flares which required increase/change in immunosuppression.

Time Frame: Within 24 months
A composite endpoint denoted by proteinuria >1g/day, presence of urinary RBC >30/hpf or RBC casts, or increase in serum creatinine by 15% compared with baseline, and anti-DNA antibody titre above the upper limit of normal
