Eligibility

Inclusion Criteria:

1. Age =18 yrs

2. Scleroderma as determined by the 2013 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria.

6. Presence of any ground-glass opacification (GGO) on thoracic high-resolution computed tomography (HRCT)

7. Repeat FVC-% at the baseline visit within 10% of the FVC-% value measured at screening. If these criteria are not met, a repeat FVC-% may be obtained within 7 days and the subject may qualify for randomization if the repeat FVC-% agrees within 10% of the FVC-% obtained at screening.

Exclusion Criteria:

1. Disease features supporting the primary diagnosis of another connective tissue disease such as rheumatoid arthritis, systemic lupus erythematosus or mixed connective tissue disease (Features consistent with a secondary Sjogren syndrome or scleroderma-associated myopathy will be allowed).

2. FVC-% of <45% at either screening or baseline.

3. Forced Expiratory Volume in the first second (FEV1)/Forced Vital Capacity (FVC) ratio <0.65 at either screening or baseline.

4. Diffusing capacity of the lung for carbon monoxide adjusted for hemoglobin, expressed as a percentage of the normal predicted value (DLCOHb-%) of <30% at screening or <25% at baseline.

a) All participants with a DLCOHb-% between 30 to 40% must have pulmonary artery pressures documented by either echocardiogram, right heart catheterization or magnetic resonance imaging in order to be considered for inclusion.

5. Diagnosis of clinically significant resting pulmonary hypertension requiring treatment or mild pulmonary hypertension requiring treatment with more than one oral medication as ascertained prior to study evaluation or as part of a standard of care clinical assessment performed outside of the study protocol.

6. Evidence of uncontrolled congestive heart failure, unstable ischemic heart disease, history of complicated pulmonary embolism impacting on heart or lung function, or unstable cardiac arrhythmia requiring chronic anticoagulation.

7. Clinically significant abnormalities on HRCT not attributable to SSc

8. Hematologic abnormality at screening including:

1. Leukopenia (white blood cells [WBC] <4.0x10^3/µl).

2. Thrombocytopenia (platelet count <120.0x10^3/µl).

3. Clinically significant anemia [Hemoglobin (Hgb) <10.0 g/dl].

Participants with an identified and correctable etiology may be eligible if repeat testing within the maximal 90-day screening period meets all criteria.

10. Serum creatinine >2.0mg/dl

11. History of recurrent aspiration, uncontrolled heartburn, or gastroesophageal reflux disease (GERD) with a reflux scale score of >1.00 as determined by a UCLA Scleroderma Clinical Trial Consortium Gastrointestinal Scale (UCLA SCTC GIT), Version 2.0.

Participants with uncontrolled heartburn or GERD that is amenable to medical management may be eligible if repeat testing within the maximal 90-day screening period meets this criteria.

12. Known achalasia, esophageal stricture or esophageal dysfunction sufficient to limit the ability to swallow medication.

If a subject chooses abstinence, then a second reliable means of contraception is not needed.

15. Prior use of potential disease modifying antirheumatic drugs (DMARDs) according to the following exposure rules:

1. Use of oral cyclophosphamide (CYC), MMF, azathioprine or other oral or short half-life DMARDs (as detailed in Protocol Section 7.5.1a) for more than 6 months in the past year as determined at the time of the initial screening visit.

2. Treatment with more than three intravenous doses of CYC, one treatment course of Rituximab or other intravenous or injectable DMARDs (as detailed in Protocol Section 7.5.1b) in the past year.

3. More distant history of treatment with a DMARD is allowed as long as the patient has a new diagnosis/new episode of active SSc-ILD since stopping that treatment and meets the criteria noted in 15a or 15b.

16. Use of CYC, MMF, azathioprine, Rituximab or other DMARD (as defined in Protocol Section 7.5.1a&b) in the 30 days prior to their baseline visit unless the patient is on MMF and the responsible physician indicates that continued use is in the best clinical interest of the patient.

17. Active infection (lung, ulcers or elsewhere) whose management would be compromised by immunosuppression.

18. Other serious concomitant medical illness (e.g., active malignancy within the past 5 years other than surgically-removed local skin cancer such as a basal cell carcinoma), chronic debilitating illness (other than SSc), unreliability or drug abuse that might compromise the patient's participation in the trial.

19. Current use, or use within the 30 days prior to their baseline visit, of prednisone (or equivalent) in doses >10 mg/day.
