Participants received Abituzumab 1500 mg administered as an intravenous infusion for 1 hour every 4 weeks up to Week 64.

Experimental: Abituzumab 500 mg Drug: Abituzumab 500 mg
Participants received Abituzumab 500 mg administered as an intravenous infusion for 1 hour every 4 weeks up to Week 64.

Placebo Comparator: Placebo Drug: Placebo
Participants received Placebo matched to Abituzumab administered as an intravenous infusion for 1 hour every 4 weeks up to Week 64.




Primary Outcome Measures :
  1. Change From Baseline in Absolute Forced Vital Capacity (FVC) at Week 52 [ Time Frame: Baseline, Week 52 ]
    FVC was the maximum amount of air exhaled from the lungs after taking the deepest breath possible. The FVC assessments were done using spirometry. Change from baseline in fvc at week 52 was reported.


Secondary Outcome Measures :
  1. Change From Baseline in Dyspnea as Measured by the Mahler's Transition Dyspnea Index (TDI) at Week 52 [ Time Frame: Baseline, Week 52 ]
    Mahler's TDI was an interview-administered instrument that allows participants to assess their level of dyspnea which was assessed by functional impairment, magnitude of task and magnitude of effort. Scores for each subscale range from -3 to +3 so that the TDI focal score ranges from -9 (major deterioration) to +9 (major improvement). For all subscale scores and the TDI focal score a higher value indicates a better outcome.

  2. Absolute Change From Baseline in St. George Respiratory Questionnaire (SGRQ) Total Score at Week 52 [ Time Frame: Baseline, Week 52 ]
    The SGRQ assesses health-related quality of life in participants with chronic pulmonary disease by evaluating 3 health domains: symptoms (distress caused by respiratory symptoms); activity (effects of disturbances on mobility and physical activity); and impacts (the effect of disease on factors such as employment, personal control of one's health, and need for medication). A composite total score is derived as the weighted sum of domain scores for symptoms, activity, and impact (0=the best possible score and 100=the worst possible score). A reduction in score of 4 units is generally recognized as a clinically meaningful improvement in quality of life.

  3. Absolute Change From Baseline in Modified Rodnan Skin Score (mRSS) at Week 52 in Participants With Diffuse Cutaneous Skin Involvement at Baseline [ Time Frame: Baseline, Week 52 ]
    The Modified Rodnan Skin Score (mRSS) measures dermal skin thickness through the examination of 17 body areas: fingers, hands, forearms, arms, feet, legs, and thighs (in pairs), and face, chest, and abdomen. The skin score is evaluated by manual palpation in each of these areas. The skin score is 0 for uninvolved skin, 1 for mild thickening, 2 for moderate thickening, and 3 for severe thickening (hidebound skin). The total skin score is the sum of the skin scores of the individual areas where the minimum score is 0 and the maximum score is 51. A higher score indicates greater severity of disease.

  4. Absolute Change From Baseline in Quantitative Lung Fibrosis (QLF) in the Region of Highest Baseline Severity at Week 52 [ Time Frame: Baseline, Week 52 ]
    Absolute change from baseline in QLF score at week 52 was calculated as the difference of the QLF score at week 52 minus the QLF score at baseline divided in the region of highest baseline severity at Week 52 .The QLF score itself ranges from 0 to 100, where greater values represent a greater amount of lung fibrosis and are considered a worse health status.

  5. Overall Survival (OS) [ Time Frame: Time from date of randomization until death, assessed up to 2 years ]
    Overall survival (OS) was defined as the time (in months) from randomization to death. Data has been presented in terms of number participants who died and number of censored participants.

  6. Number of Participants With Clinically Meaningful Progression of Systemic Sclerosis (SSc) by Meeting Criterion 1 (Interstitial Lung Disease [ILD]) [ Time Frame: upto Week 52 ]
    Clinically Meaningful Progression SSc-ILD was defined as one of the following (in the absence of causative intercurrent illness) on at least 2 occasions within approximately 4 weeks (per Outcome Measures in Rheumatology criteria): Relative decrease from baseline in forced vital capacity (FVC) % predicted greater than or equal to (>=)10%; Relative decrease from baseline in FVC % predicted of >=5% to less than (<) 10% and relative decrease from baseline in Diffusion capacity of the lung for carbon monoxide % predicted >=15%.

  7. Number of Participants With Clinically Meaningful Progression of Systemic Sclerosis (SSc) by Meeting Criterion 2 (SSc Progression Other Than ILD) [ Time Frame: upto Week 52 ]
    Clinically Meaningful Progression SSc other than ILD was defined as new onset of one or more of the following: Scleroderma renal crisis; Left ventricular failure (defined as ejection fraction <=45%); Pulmonary arterial hypertension requiring treatment.

  8. Number of Participants With Clinically Meaningful Progression [ Time Frame: upto Week 52 ]
    Participants meeting one or both of the below criteria was considered as having clinically meaningful disease progression. Clinically Meaningful SSc-ILD defined as one of the following (in the absence of causative intercurrent illness) on at least 2 occasions within approximately 4 weeks (per Outcome Measures in Rheumatology criteria): Relative decrease from baseline in forced vital capacity (FVC) % predicted greater than or equal to (>=)10%; Relative decrease from baseline in FVC % predicted of >=5% to less than (<) 10% and relative decrease from baseline in Diffusion capacity of the lung for carbon monoxide % predicted >=15%. Clinically Meaningful SSc progression other than ILD defined as new onset of one or more of the following: Scleroderma renal crisis; Left ventricular failure (defined as ejection fraction <=45%); Pulmonary arterial hypertension requiring treatment.

  9. Number of Participants With Absolute Decrease From Baseline of FVC Percentage (%) Predicted Greater Than or Equal to (>=) 10% on 2 or More Consecutive Occasions at Least 4 Weeks Apart [ Time Frame: upto Week 52 ]
    FVC is the maximum amount of air exhaled from the lungs after taking the deepest breath possible. The FVC assessments were done using spirometry.

Inclusion Criteria:

  • Participants were eligible for this trial if they fulfill all of the following inclusion criteria:
  • Female or male participants aged between 18 and 75 years of age who provide informed written consent.
  • Participants fulfilling the 2013 American College of Rheumatology (ACR) /European League Against Rheumatism criteria for classification of systemic sclerosis (SSc).
  • Disease duration of less than (<) 7 years from first non-Raynaud's symptom.
  • Participants who had been taking the same mycophenolate regimen (stable dose) in a range of 1.5 to 3 gram (g)/day of Mycophenolate mofetil (MMF) or 1080 to 2160 milligram/day (mg/day) of MPS for at least 2 months prior to the Screening Visit and continued through Day 1 of the Treatment Period, of the lung on HRCT according to central reading.
  • According to central readings: Diffusion capacity of the lung for carbon monoxide (DLCO) greater than or equal to (>=) 30 percent (%) predicted, Forced vital capacity (FVC) 40% to 85% predicted, and a ratio of FVC % predicted to DLCO % predicted >=1.8 is acceptable if right heart catheterization within 3 months of screening revealed no pulmonary hypertension. If these criteria were met, then High-resolution computed tomography (HRCT) of lungs will be performed, and must show at least 5% fibrosis for participants to be eligible.
  • Female participants of childbearing potential must use a highly effective method of contraception to prevent pregnancy for 4 weeks before randomization and must agree to continue to practice adequate contraception for the duration of their participation in the trial (up to the last Safety Follow-Up Visit). For the purposes of this trial, women of childbearing potential were defined as "All female participants after puberty unless they were post-menopausal for at least 2 years or weresurgically sterile." Highly effective contraception is defined as 2 barrier methods (eg, female diaphragm and male condoms); or 1 barrier method with at least one of the following: spermicide, a hormonal method, or an intrauterine device. Note that because mycophenolate affects the metabolism of oral contraceptives and may reduce their effectiveness, women receiving mycophenolate who were using oral contraceptives for birth control should employ an additional contraceptive method (for example, male or female barrier method).
