RO7303509 for Systemic Sclerosis
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the safety and effects of a new treatment called RO7303509, an experimental therapy for systemic sclerosis, a condition that causes hardening and tightening of the skin and connective tissues. Participants receive the treatment through a series of increasing doses to assess tolerance. Individuals diagnosed with systemic sclerosis who first noticed symptoms other than Raynaud's within the last 10 years might find this trial suitable. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. However, if you have an active rheumatic autoimmune disease other than systemic sclerosis that requires treatment with disease-modifying therapy, you may be excluded from participating.
Is there any evidence suggesting that RO7303509 is likely to be safe for humans?
Research has shown that RO7303509 has been well tolerated in humans so far. In earlier studies with healthy volunteers, researchers administered single doses up to 1200 mg. The treatment showed good results, meaning it didn't cause serious problems and was absorbed by the body as expected. These findings are promising for its safety in people with systemic sclerosis. The current study takes extra precautions by starting with lower doses and gradually increasing them to ensure safety for participants.12345
Why do researchers think this study treatment might be promising for systemic sclerosis?
Researchers are excited about RO7303509 for systemic sclerosis because it offers a novel approach by targeting specific pathways involved in the disease. Unlike current treatments that primarily focus on managing symptoms and slowing disease progression, RO7303509 is designed to directly modulate the underlying disease mechanisms. It is administered as a subcutaneous injection, which might offer greater convenience and potentially improved compliance compared to more invasive treatments. By addressing the root causes rather than just the symptoms, RO7303509 has the potential to provide significant benefits for patients with systemic sclerosis.
What evidence suggests that RO7303509 might be an effective treatment for systemic sclerosis?
Research has shown that RO7303509 could be a promising treatment for systemic sclerosis, a condition that causes thickening and scarring of connective tissue. This treatment targets a protein called TGFβ3, which plays a role in the scarring process. Studies have found that RO7303509 is safe for healthy individuals and is processed well by the body. Early results suggest it might help reduce scarring, making it a potential therapy for systemic sclerosis. However, more research is needed to confirm its effectiveness for this condition. Participants in this trial will receive RO7303509, with some in the MAD stage randomized to receive either the study drug or a placebo.12467

What Are the Treatments Tested in This Trial?
Interventions
- RO7303509
Trial Overview
The study is testing RO7303509's safety and how the body processes it in people with systemic sclerosis over a period of up to 65 weeks. Participants will receive increasing doses of RO7303509 or placebo during a first phase (12 weeks), followed by an optional long-term safety extension where everyone gets RO7303509.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Every participant in the OSE stage will receive study drug and no participant will receive placebo. Participants will receive RO7303509 as SC injection at the same dose as that administered during the MAD stage, one time per month for up to a year.
Participants will be randomized in a ratio of 4:1 to receive RO7303509 or placebo, as subcutaneous (SC) injection, one time per month for 3 months. You have a 20% chance of getting placebo.
