Inclusion Criteria:

1. Provide written informed consent prior to any study procedures and who agree to adhere to all protocol requirements.
2. Aged 18 to 75 years inclusive at the time of consent.
3. Have a classification of systemic sclerosis, as defined by American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) criteria with disease duration ≤5 years from first non-Raynaud phenomenon manifestation.
4. Have a diagnosis of diffuse cutaneous SSc defined as systemic sclerosis with skin thickening on the upper arms proximal to the elbows, on the upper legs proximal to the knees, or on the trunk.
5. Have skin thickening in a body area suitable for repeat biopsy.
6. Have a mRSS at Screening of ≥15 to ≤40.
7. FVC ≥50% of predicted at Screening.
8. If on azathioprine, mycophenolate mofetil, or hydroxychloroquine, have been on a stable dose for at least 2 months prior to baseline.
9. Women of childbearing potential (WOCPB) and males with partners of child-bearing potential must agree to use highly effective contraception (a failure rate of <1%), for the duration of the study and until three months after their last dose of IMP.

Exclusion Criteria:

1. Pregnant or breast-feeding, or plan to become pregnant during the study.
2. Have received any IMP within 30 days or 5 half-lives prior to randomisation (4 months if the previous drug was a new chemical entity), whichever is longer.
3. Have known or suspected contraindications to the IMP.

Have severe or unstable SSc or end-stage organ involvement as evidenced by:

1. On an organ transplantation list or has received an organ transplant including autologous stem cell transplant.
2. Renal crisis within 1 year prior to Baseline.
3. Interstitial lung disease or pulmonary hypertension requiring constant oxygen therapy. This excludes oxygen used to aid sleep or exercise.
4. Gastrointestinal dysmotility requiring total parenteral nutrition or requiring hospitalisation within the 6 months prior to Baseline.
5. Concomitant inflammatory myositis, rheumatoid arthritis, or systemic lupus erythematosus when definite classification criteria for those diseases are met (Bohan and Peter criteria for polymyositis and dermatomyositis)
6. SSc-like illnesses related to exposures or ingestions

The use of the following drugs within the specified periods:

1. Methotrexate in the 2 weeks prior to Day 1
2. Other anti-fibrotic agents including D-penicillamine or tyrosine kinase inhibitors (nilotinib, imatinib, dasatinib) in the month prior to Screening.
3. Biologic drugs such as tumour necrosing factor (TNF) inhibitors, tocilizumab, or Janus kinase (JAK) inhibitors, in the 3 months prior to Screening.
4. Rituximab in the 6 months prior to Screening.
5. Cyclophosphamide oral or IV in the 3 months prior to Screening.
6. Oral prednisolone >10 mg per day or IV steroids in the month prior to Screening.
7. Have any malignancy not considered cured (except basal cell or squamous cell carcinoma of the skin, or carcinoma in situ of the cervix); a subject is considered cured if there has been no evidence of cancer recurrence for the 6 years prior to randomisation.
8. Have aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transferase (GGT), lactate dehydrogenase (LDH), or bilirubin values above the upper limit of normal (ULN) at Screening or Baseline, or evidence of hepatic disease as determined by any one of the following: history of hepatic encephalopathy, history of oesophageal varices, or history of portacaval shunt.
9. Estimated glomerular filtration rate (eGFR) <60mL/min, urinary albumin/creatinine ratio <30mg/g.
10. Haemoglobin < 80 g/L, platelets < 90 x 109/L, or neutrophil count < 1.4 x 109/L
11. Other than SSc, have any other medical condition or significant co-morbidities, clinically relevant social or psychiatric conditions, or any finding during Screening, which in the investigator's opinion may put the subject at risk or interfere with the study objectives.
