PRA023 for Systemic Sclerosis-Associated ILD (ATHENA-SSc-ILD Trial)

Phase 2
Recruiting
Research Sponsored by Prometheus Biosciences, Inc., a subsidiary of Merck & Co., Inc. (Rahway, New Jersey USA)
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Has diffuse cutaneous scleroderma
Has systemic sclerosis related interstitial lung disease confirmed by HRCT
Must not have
Has any active infections, a serious infection within the past 3 months, or chronic bacterial infection
Has current clinical diagnosis of another inflammatory connective tissue disease
Timeline
Screening 3 weeks
Treatment Varies
Follow Up up to week 50

Summary

This trial tests a new medication called tulisokibart on people with a lung disease called SSc-ILD. The goal is to see if it is safe and helps improve their condition.

Who is the study for?
This trial is for people with systemic sclerosis that started within the last 5 years and associated lung disease, who are not current smokers. They must have a certain level of lung function and be on stable medication doses. Participants need to use effective contraception and cannot join if they have other inflammatory diseases, serious recent infections, or significant heart or lung complications.
What is being tested?
The study tests PRA023's safety and effectiveness in treating systemic sclerosis-related lung disease compared to a placebo. A companion diagnostic tool is also used. The goal is to see if PRA023 can help manage this condition better than existing treatments.
What are the potential side effects?
While specific side effects for PRA023 aren't listed here, similar medications may cause immune system reactions, infusion-related discomforts, fatigue, digestive issues like nausea or diarrhea, skin reactions at injection sites, and increased risk of infections.

Other Research
The most common treatments for Systemic Sclerosis (SSc) include immune modulators, anti-fibrotic agents, and anti-inflammatory agents. Immune modulators alter the immune system's activity to reduce the abnormal immune response in SSc. Anti-fibrotic agents aim to prevent or reduce fibrosis, the thickening and scarring of connective tissue. Anti-inflammatory agents reduce inflammation, helping to manage symptoms and prevent further tissue damage. These mechanisms are crucial for SSc patients as they target the underlying disease processes, potentially improving outcomes and quality of life.
Challenges in the treatment of psoriasis with biologics: vaccination, history of malignancy, human immunodeficiency virus (HIV) infection, and pediatric psoriasis.
