Brief Summary:
Scleroderma is a rare, long-term autoimmune disease in which normal tissue is replaced with dense, thick fibrous tissue. Normally, the immune system helps defend the body against disease and infection. In people with scleroderma, the immune system triggers fibroblast cells to produce too much of the protein collagen. The extra collagen becomes deposited in the skin and organs, causing hardening and thickening that is similar to the scarring process. Although scleroderma most often affects the skin, it also can affect other parts of the body, including the lungs, and in its most severe forms scleroderma can be life-threatening. Scleroderma-related interstitial lung disease is one example of a life-threatening scleroderma condition. In people with symptomatic scleroderma-related interstitial lung disease, scarring occurs in the delicate lung tissue, compromising lung function. The purpose of this study is to determine whether people with symptomatic scleroderma-related interstitial lung disease experience more respiratory benefits from treatment with a 2-year course of mycophenolate mofetil or treatment with a 1-year course of oral cyclophosphamide.

| Scleroderma Interstitial Lung Disease | Drug: Mycophenolate mofetil Drug: Cyclophosphamide Drug: Placebo | Phase 2 |
Interstitial lung disease describes a condition in which the lung tissue has become scarred or inflamed. Interstitial lung disease caused by scleroderma, specifically seen as progressive pulmonary fibrosis, occurs in approximately 40 percent of patients with scleroderma and has emerged as the leading overall cause of death.
In a previous study, the Scleroderma Lung Study I (SLS I), investigators evaluated a 1-year cyclophosphamide (CYC) treatment for people with scleroderma-related interstitial lung disease. The study results demonstrated statistically significant improvements in forced vital capacity, total lung capacity, dyspnea, Rodnan skin scores, and several measures of quality of life. However, when patients were followed for another year after completing their CYC therapy, the beneficial effects of CYC waned and were no longer significant by the 24-month follow-up. Preliminary information suggests that an alternative immunosuppressive medication, mycophenolate mofetil (MMF), may be effective in treating this disease, be given for longer periods, and result in fewer side effects.
This study, the Scleroderma Lung Study II (SLS II), will compare the safety and efficacy of a 2-year treatment with MMF versus a 1-year treatment with CYC. Specifically, investigators will determine whether MMF produces similar or better improvements in lung capacity and fewer side effects throughout the entire 2-year period.
Participation will include about 21 study visits over a 2-year period. Eligible participants will be randomly assigned to receive either MMF twice daily for 2 years or CYC once daily for 1 year, followed by placebo for 1 year. Blood and urine samples will be collected every 2 weeks for the first 2 months and then once a month for the remainder of the study. Every 3 months, participants will attend study visits that will include pulmonary function tests, blood and urine sampling, a physical exam, and questionnaires about current health and medications. At the final study visit, participants will also undergo a high resolution computerized tomography (HRCT) scan and possibly a punch biopsy.

Primary Outcome Measures :
- Forced Vital Capacity (FVC), as a Percent of the Age, Height, Gender, and Ethnicity Adjusted Predicted Value [ Time Frame: Measured at study Baseline and Months 3, 6, 12, 15, 18, 21, and 24 ]The primary outcome is the course over time from baseline to 24 months for the FVC %-predicted. The FVC %-predicted represents the adjusted volume of air (adjusted as a percentage of the expected normal valued based on the participant's age, height, gender and ethnicity) that can be forcibly exhaled from the lungs after taking the deepest breath possible. The FVC %-predicted is reduced in patients with interstitial lung disease and is used as a measure of lung involvement and disease severity.
Secondary Outcome Measures :
- Total Lung Capacity (TLC), as a Percent of the Age, Height, Gender, and Ethnicity Adjusted Predicted Value [ Time Frame: Measured at study entry and Months 6, 12, 18, and 24 ]The TLC represents the total volume of air within the lung after taking the deepest breath possible and the TLC %-predicted represents the TLC expressed as a percentage of the expected normal valued based on the participant's age, height, gender and ethnicity. The TLC %-predicted is reduced in patients with interstitial lung disease and is used as a measure of disease severity.
- Single-breath Diffusing Capacity for Carbon Monoxide (DLCO), as a Percent of the Age, Height, Gender, and Ethnicity Adjusted Predicted Value [ Time Frame: Measured at study entry and Months 3, 6, 12, 15, 18, 21, and 24 ]The DLCO is a pulmonary function test that measures the capacity for the lung to carry out gas exchange between the inhaled breath and the pulmonary capillary blood vessels and the DLCO %-predicted represents the DLCO expressed as a percentage of the expected normal valued based on the participant's age, height, gender and ethnicity. The DLCO %-predicted is reduced in patients with interstitial lung disease and is used as a measure of disease severity.
- Fibrosis Score, as Measured by Thoracic High Resolution Computerized Tomography (HRCT) [ Time Frame: Measured at baseline and Month 24 ]Imaging of the whole lung (WL) is performed using a volumetric high resolution computerized tomography (HRCT) scan, which is then analyzed using a computer algorithm to determine the percentage of overall pixels exhibiting features characteristic for quantitative lung fibrosis (QLF). Higher percentages for QLF-WL therefore represent greater involvement by lung fibrosis.
- Transitional Dyspnea Index Score [ Time Frame: Measured at Months 6, 12, 18, and 24 ]Change in breathlessness was assessed using the Transitional Dyspnea Index, which compares current symptoms to those at baseline. Total score ranges from - 9 to + 9. The lower the score, the more deterioration in severity of dyspnea.
- Health-related Quality of Life as Measured by the Patient Responses to the Health Assessment Questionnaire Disability Index (HAQ-DI) [ Time Frame: Measured at study entry and Months 3, 6, 9, 12, 15, 18, 21, and 24 ]The HAQ-DI asks questions related to 8 activity domains (dressing, arising, eating, walking, hygiene, reach, grip, and common daily activities) with the patient's capacity to carry out each activity scored from 0 to 3. Scores across all domains are averaged and a higher score represents greater disability.
- Skin Involvement, as Measured by the Modified Rodnam Skin Thickness Scores (mRSS) [ Time Frame: Measured at baseline and Months 3, 6, 9, 12, 15, 18, 21, and 24 ]Skin thickness is quantified using the modified Rodnan measurement method (mRSS), with a scale that ranges from 0 (no skin involvement) to a maximum of 51. The reported skin score is determined by a clinical assessment of skin thickness, which is performed by a trained reader, and represents the sum of individual assessments that are made in each of 17 body areas. Each area is given a score in the range of 0-3 (0 = normal; 1= mild thickness; 2 = moderate; 3 = severe thickness). A higher score represents more severe skin involvement.
- Toxicity, as Measured by Adverse Events, Serious Adverse Events, and Death [ Time Frame: Measured throughout the 2-year study ]
- Tolerability, as Assessed by the Time to Withdrawal From the Study Drug or Meeting Protocol-defined Criteria for Treatment Failure. [ Time Frame: Continuous assessment from randomization to 24 months ]The number of participants who remained in the study at the listed time points are reported
