Read the detailed description

This is a prospective, single-arm, single-center, explorative clinical trial to evaluate the effect of Rituximab on disease progression in subjects with SLE-PAH receiving concurrent stable-dose standard medical therapy with a prostanoid, endothelin receptor antagonist, phosphodiesterase 5 (PDE-5) inhibitor, and/or guanylate cyclase stimulators.

Objective. The study will focus on assessment of clinical response and safety measures longitudinally.The primary objective of this study is to explore the safety and efficacy of Rituximab in patients with SLE-PAH. In addition, the biomarker of treatment efficacy with Rituximab and pathogenic autoantibody response in this disease will be investigated.

Study population. Subjects with SLE-PAH with mean pulmonary artery pressure ≥25mmHg, pulmonary artery wedge pressure ≤15mmHg, and pulmonary vascular resistance > 3WU as measured by right heart catheterization will be enrolled. The diagnosis of SLE-PAH should be confirmed by a rheumatologist experienced in the diagnosis and treatment of systemic lupus erythematosus in conjunction with a cardiologist specializing in management of PAH. Both specialists will be part of the study team at each site.

Treatment. Rituximab will be administered as two IV infusions of 1000 mg each, given two weeks apart at Day 0 and Week 2. All subjects will receive 40 mg of prednisone orally the night before and morning of each infusion with diphenhydramine and acetaminophen orally thirty to sixty minutes prior to each infusion of rituximab. Subjects will remain on their baseline standard medical regimen.

Fifty eligible subjects will be accrued. Each potential study subject will provide written informed consent prior to screening procedures. All inclusion and exclusion criteria must be met at time of recruitment prior to receipt of the first dose of rituximab (Day 0, Treatment Initiation).

Clinical assessments and sample collection will occur regularly through Week 24 with telephone follow-up conducted intermittently. The peripheral proteome, bulk-RNA sequencing, whole exome sequencing, cytokine profile, and T/B cell subsets will be assessed in 0 and Week 24. During this study, AEs and SAEs will be assessed, providing the subject has not withdrawn consent, to capture any infectious event ≥ Grade 3 using the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE). No additional study-related data will be collected.

The primary efficacy endpoint is the change in pulmonary vascular resistance (PVR) from baseline to 24 weeks after treatment initiation. Hemodynamic measures will be assessed at baseline and Week 24, contributing to the understanding of the relationship between PVR and clinical endpoints. Time to clinical worsening will be assessed as a secondary outcome measure through Week 24, contributing to the understanding of the relationship between PVR and clinical endpoints. Initiation of new therapy due to disease worsening prior to Week 24 will prompt an endpoint visit and right heart catheterization prior to initiation of the new therapy. The mechanistic study objective is to identify biomarkers which correlate with treatment response as measured by exercise capacity (6MWD) and PVR (right heart catheterization). Proteomics, whole exome sequencing, cytokine profile,TB cell subsets, and bulk-RNA sequencing will be measured before and after rituximab treatment. The other mechanistic objective is to determine if the biomarkers anti-U1 RNP, anti-cardiolipin, and other autoantibodies, and quantitative immunoglobulin levels, including IgG subclasses, correlate with treatment response as measured by PVR (right heart catheterization).

The total duration of the study is anticipated to be approximately 3 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. pulmonary vascular resistance (PVR)

    PVR as assessed by right heart catheterization, the gold standard method to assess cardiopulmonary haemodynamics. Standardized Fick-based pulmonary vascular resistance (PVRf, in Woods Units) are calculated as follows: PVR = TPG / CO, where TPG = Transpulmonary Gradient (mmHg), CO = Cardiac Output (L/min)

    Measured: 0-24 weeks

Secondary outcomes (8)
  1. 6MWD

    The amount of change in 6-minute walking distance (6MWD) from baseline to 24 weeks to evaluate changes in athletic ability

    Measured: 0-24 weeks

  2. Right atrium Pressure (RAP)

    Changes in Right Atrial Pressure (RAP) measured by Right Heart Catheter (RHC) from baseline to 24 weeks. the right atrial (RA) pressure waveform reflects both venous return to the right atrium during ventricular systole and right ventricular end-diastolic pressure. Normal RA pressures range from 0 to 7 mmHg

    Measured: 0-24 weeks

  3. Cardiac Index (CI)

    Changes in Cardiac Index (CI) measured by Right Heart Catheter (RHC) from baseline to 24 weeks. Cardiac Index = Cardiac Output / Body Surface Area. The pulmonary artery catheter (PAC) measures the cardiac output (CO) via either the indicator thermodilution method or the Fick method. Normal hemodynamic measures for CI are 2.8 to 4.2 L/min/m2

    Measured: 0-24 weeks

  4. Clinical worsening

    clinical worsening: includes the first occurrence of any of the following: death, hospitalization due to PAH, increased PAH targeted drugs, deterioration of 6MWD>20%, and deterioration of WHO cardiac function grading.

    Measured: 0-24 weeks

  5. BNP/NT proBNP

    Changes in serological indicators (BNP/NT proBNP) from baseline to 24 weeks. Trending BNP levels can be a useful component of globally assessing the patient's clinical course and monitoring response to treatment. BNP and N-terminal pro-BNP (NT-proBNP) are biomarkers that are commonly used to assess severity and monitor response to therapy in patients with heart failure.

    Measured: 0-24 weeks

  6. Patients' quality of life

    Changes in patients' quality of life as assessed by short form 36 (SF-36) from baseline to 24 and 48 weeks. Short-Form 36 (SF-36) is a self-report health-related quality-of-life (HRQOL) questionnaire, widely used in dialysis patients. It consists of physical and mental component scores (PCS/MCS), ranging from 0 to 100.

    Measured: 0-24 weeks

  7. SLEDAI

    Changes in the SLE Disease Activity Index (SLEDAI) of patients from baseline to 24 weeks. The Systemic Lupus Erythematosus Disease Activity Index-2K (SLEDAI-2K) is a scoring systems for global disease activity, ranging from 0 to105 points. SLEDAI includes 9 modules: neurological involvement, vascular involvement, kidney involvement, musculoskeletal involvement, serosal involvement, skin involvement, immunological abnormalities, systemic symptoms, and hematological involvement.

    Measured: 0-24 weeks

  8. low-risk stratification

    The proportion of patients who met the low risk stratification of the 2022 ESC/ERS pulmonary hypertension guidelines within 24 weeks

    Measured: 0-24 weeks
