Resumen

The purpose of this trial was to compare two doses of abituzumab with placebo and determine whether abituzumab was more effective, safer, would be better tolerated and could provoke better immune response than placebo in the treatment of participants with SSc-ILD who already receive constant doses of mycophenolate.

Elegibilidad

Edad mínima: 18 YearsEdad máxima: 75 YearsSexo: ALL

Criterios de inclusión

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).
