Diffuse Scleroderma clinical trials at University of California Health

This is a randomized, double-blind, placebo-controlled, repeat-dose, multicenter trial. Participants will be screened within 6 weeks prior to the Baseline (Day 1) Visit. Approximately 300 participants who meet the trial eligibility criteria will be randomized on Day 1 in a 1:1:1 ratio to receive HZN-825 300 mg QD, HZN-825 300 mg BID or placebo for 52 weeks. The trial will include up to a 42-day Screening Period and a 52-week Double-blind Treatment Period. Participants will take their first dose of trial drug at the clinic and will participate in trial visits at Week 4 and every 6 weeks thereafter until Week 52. All participants who complete the Double-blind Treatment Period (Week 52) will be eligible to enter a 52-week extension trial (HZNP-HZN-825-302, NCT05626751). Participants not entering the extension trial will participate in a Safety Follow-up Visit 4 weeks after the last dose of trial drug.

This study is open to adults aged 18 and older or above legal age who have systemic sclerosis. People can participate if they have a specific subtype called diffuse cutaneous systemic sclerosis. People with another subtype called limited cutaneous systemic sclerosis can also participate if they are anti Scl-70 antibody positive. Systemic sclerosis is also called scleroderma. The purpose of this study is to find out whether a medicine called Avenciguat (BI 685509) helps people with scleroderma who have symptoms due to lung fibrosis or vascular problems. Participants are put into 2 groups by chance. One group takes Avenciguat (BI 685509) tablets 3 times a day and the other group takes placebo tablets 3 times a day. Placebo tablets look like BI 685509 tablets but do not contain any medicine. Participants take the tablets for at least 11 months. Afterwards, participants can continue to take the tablets until the last participant has completed the 11-months treatment period. This means that the time in the study and duration of treatment is different for each participant, depending on when they start the study. At the beginning of the study, participants visit the study site every 2 weeks. The time between the visits to the study site gets longer over the course of the study. After the 11-months treatment period, participants visit the study site every 3 months. During the study, participants regularly do lung function tests. The results are compared between the 2 groups to see whether the treatment works. The participants also regularly fill in questionnaires about their scleroderma symptoms. The doctors regularly check participants' skin condition and general health and take note of any unwanted effects.

Primary Objectives: 1. The primary efficacy objective is to assess the efficacy of 52 weeks of open-label treatment with HZN-825 in participants with diffuse cutaneous systemic sclerosis, as measured by change from both baselines in forced vital capacity percent (FVC %) predicted. 2. The primary safety objective is to examine the safety and tolerability of 52 weeks of open-label treatment with HZN-825, inclusive of, but not limited to, adverse events (AEs), serious AEs (SAEs) and the adverse event of special interest (AESI), from Day 1 to 4 weeks after last dose.

The purpose of this study is to evaluate the efficacy and safety of treatment with subcutaneous anifrolumab versus placebo in adult participants with systemic sclerosis. The target population for this study includes patients who meet the 2013 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification for systemic sclerosis, either limited or diffuse cutaneous subsets, with a disease duration of less than 6 years from first non-Raynaud's phenomenon symptom.

The purpose of this trial is to evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of EHP-101 in adult subjects with diffuse cutaneous Systemic Sclerosis (dcSSc).

The goal of this clinical trial is to test efficacy of different investigational products (IPs) compared with placebo on the change from baseline to the end of the treatment period at Week 52 in lung capacity in participants with Interstitial Lung Disease Secondary to Systemic Sclerosis.
