Cyclophosphamide and Hydroxychloroquine for Thrombocytopenia in SLE (CHORUS)

February 26, 2022 updated by: Chinese SLE Treatment And Research Group

Cyclophosphamide and Hydroxychloroquine for the Treatment of Severe Thrombocytopenia in Systemic Lupus Erythematosus

Treating severe thrombocytopenia is a challenge in the management of systemic lupus erythematosus. Although rheumatologists have followed some rules in real practice,there is very few evidence to support the current treatment algorithm. The purpose of this study is to compare the complete remission rate and partial remission rate of cyclophosphamide and hydroxychloroquine for treating severe thrombocytopenia in Chinese SLE patients.

Study Overview

Status

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

This is a prospective,randomized,open-label,multi-center clinical trial. The aim of this study is to test the efficacy of GC(gluco-corticosteroid)+HCQ(hydroxychloroquine) and GC(glucocorticosteroid)+CTX(cyclophosphamide) with sequential AZA(azathioprine) in the induction and maintenance therapy of severe thrombocytopenia in SLE patients.

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.

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
Measure Description
Time Frame
complete remission rate
Time Frame: at 12 month
percentage of patients whose platelet count > 100X109/L
at 12 month

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
Measure Description
Time Frame
partial remission rate
Time Frame: at 12 month
percentage of patients whose platelet increase to >30X109/L or with at least a two folds increase of the baseline(ie, pretreatment) count and the absence of bleeding
at 12 month
