Brief Summary

Systemic sclerosis (SSc) is characterized by autoimmunity and vasculopathy resulting in fibrosis of the skin and internal organs including the Gastrointestinal (GI) tract. Key unmet clinical needs are the availability of non-invasive biomarkers for early diagnosis of SSc-GI, further characterization of different stages of SSc-GI and SSc-GI treatment response. The investigators propose combining MRI FDG-PET with MRI T1-MOLLI mapping, which has been applied to cardiac imaging to quantify histologically correlated cardiac fibrosis. T1-MOLLI enables detection and quantification of diffuse fibrosis without the need for contrast. Aim 1: FDG-PET-MRI imaging (primary biomarker) and stool markers (secondary biomarker) will be compared between patients with VEDOSS/early SSc and those with late SSc not on immunosuppressive treatment. Aim 2: Evaluation of change in biomarker levels from pre-treatment baseline to 6 months (primary end-point) and 12-months (secondary end-point) following MMF treatment, in early SSc patients Using precision medicine approach in diagnosis and treatment evaluation, the investigators anticipate that this study will contribute significantly to advance management strategies for, and improve outcomes of SSc-GI disease.

Conditions

Systemic Sclerosis; Scleroderma

Keywords

Systemic Sclerosis; Imaging, Diagnostic; MRI Scans; PET-MRI Scan

Outcome Measures

Primary Outcomes (2)

• Inflammatory or fibrosis FDG-PET-MRI imaging biomarkers in VEDOSS/early SSc or late SSc patients not on immunosuppresive treatment

  PET-MRI imaging biomarkers: Inflammatory biomarker: PET SUV tissue to background ratio (TBR); fibrosis biomarker: native T1-MOLLI value.

  Baseline

• Inflammatory biomarkers on FDG-PET-MRI imaging after 6 months (primary endpoint) and 12 months (secondary endpoint) of Mycophenolate mofetil treatment.

  Change in PET SUV TBR from baseline at 6 months (Primary endpoint) and 12 months (secondary endpoint) following Mycophenolate mofetil treatment

  Baseline, 6-month and 12-month

Secondary Outcomes (2)

• FDG-PET-MRI imaging over one year in patients with VEDOSS/early SSc not on immunosuppresive treatment

  Baseline and 12-month

• Stool biomarkers

  baseline, 6 and 12 months

Study Arms (3)

Aim 1

The investigators will compare PET-MRI imaging and stool biomarkers between patients with VEDOSS/early SSc (n=40) and those with late SSc (n=20) not on immunosuppressive treatment. Participants will undergo a PET-MRI scan once at baseline.

Diagnostic Test: PET-MRI scan

Aim 2

In early SSc patients (n=35), the investigators will determine change in biomarker levels from pre-treatment baseline to 6 months (primary end-point) and 12-months (secondary end-point) following MMF treatment. Participants will undergo PET-MRI scans at baseline, 6-month and 12-month.

Diagnostic Test: PET-MRI scan

Exploratory aim

In patients with VEDOSS/early SSc (n=15) not on immunosuppressive treatment, the investigators will characterize imaging and stool biomarker changes over one year. Participants will undergo PET-MRI scans at baseline and 12-month.

Diagnostic Test: PET-MRI scan

Interventions

PET-MRI scan DIAGNOSTIC_TEST

Participants will be scanned centrally at Clinical Imaging Research Centre (CIRC, Singapore), on a Biograph mMR PET-MR scanner. Combined FDG-PET-MRI scan is critical for co-registration of peristaltic bowel for optimal image quality. The oesophagus to anorectum will be imaged. The PET-MRI scan starts 60 minutes post-FDG injection of 6mCi and immediately after injecting 10mg hyoscine butylbromide to reduce peristalsis. MRI sequences are non-contrast.
