Clinical Study of Divozilimab in Patients With Systemic Scleroderma (LIBERIUS)

June 8, 2026 updated by: Biocad

A Randomized, Double-Blind, Placebo-Controlled Clinical Study of the Efficacy and Safety of Divozilimab in Patients With Systemic Scleroderma

The study is a randomized, double-blind, placebo-controlled clinical study of the efficacy and safety of divozilimab in patients with systemic scleroderma.The study will enroll adult patients of both sexes diagnosed with active systemic scleroderma according to the ACR/EULAR 2013 criteria with a modified Rodnan skin score (mRSS) of 10 to 20. In patients having signs of ILD, the Forced Vital Capacity (FVC) should be at least 40 % of the due value.

The study will include patients of either sex aged ≥16 years with systemic scleroderma according to the ACR/EULAR 2013 criteria, with a modified Rodnan skin score (mRSS) ≥10 and ≤20 , as well as patients of either sex aged ≥14 and <16 years with systemic scleroderma according to the PRES/ACR/EULAR 2007 criteria. In patients having signs of ILD, the Forced Vital Capacity (FVC) should be at least 40 % of the due value. Subjects aged ≥18 years will be randomized to divozilimab or placebo group. Subjects aged <18 years (not less than 16) will receive divozilimab.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in the modified Rodnan Skin Score (mRSS) from baseline
Time Frame: week 48
The modified Rodnan Skin Score (mRSS) describes the thickness of skin in 17 anatomic areas rated from 0 to 3, where 3 indicates the most severe thickening.
week 48

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Forced Vital Capacity (FVC) from baseline
Time Frame: week 48
FVC (Forced Vital Capacity) desribes pulmonary function. FVC will be assessed using a spirometer.
week 48
