(BLISSc-ILD)
What this study is about
This study investigates the effectiveness and safety of belimumab compared to placebo, in addition to standard therapy, for the treatment of participants with systemic sclerosis associated interstitial lung disease (SSc-ILD).
View original scientific description
This study investigates the efficacy and safety of belimumab compared to placebo, in addition to standard therapy, for the treatment of participants with systemic sclerosis associated interstitial lung disease (SSc-ILD). The study will evaluate the effect of belimumab treatment on lung function as well as on extra-pulmonary disease manifestations, including skin thickening and general symptoms, such as fatigue, that impact quality of life (QoL).
Interventions
BIOLOGICAL
Belimumab
Belimumab will be administered.
OTHER
Placebo
.Placebo will be administered.
Primary outcome measures
Absolute change from baseline in Forced Vital Capacity (FVC) millilitre (mL) at Week 52
Time frame: Baseline and Week 52

Documented diagnosis of SSc as defined by the American College of Rheumatology / European League Against Rheumatism 2013 SSc classification criteria. 3. Diffuse cutaneous disease, defined as presence of thickened skin with mRSS \>0 over at least one skin area proximal to elbows and/or knees in addition to distal areas involvement on Day 1. 4. Total mRSS ≥15 on Day 1. 5. Evidence of interstitial lung disease on centrally read screening HRCT. 6. Anticentromere antibody negative on central test at screening. 7. Evidence for active or progressive disease 8. Participant has an area of uninvolved or mildly thickened skin that, in the opinion of the investigator, would allow SC injection at the abdomen or the front, middle region of the thigh. 9.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
