We’re tracking 7 recruiting myositis studies with a site in California — including Phase 1, Phase 2, Phase 2/Phase 3 and Phase 3 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT06154252RecruitingPhase 2/Phase 3
Study of CABA-201 for active myositis in adults and children
This trial tests a new treatment called CABA-201, which uses your own immune cells modified to attack the overactive cells causing myositis. It is for people with active disease that hasn't improved enough with standard therapies.
Orange, CaliforniaAges 6–75 - NCT07391605RecruitingPhase 2
Descartes-08 for treatment-resistant myositis
This trial tests a new treatment called Descartes-08 for people with dermatomyositis or antisynthetase syndrome whose disease hasn't responded well to standard therapies. It aims to see if this treatment can help control muscle and skin symptoms.
Orange, CaliforniaAges 18 years+ - NCT05979441Enrolling by invitationPhase 3
Long-term safety of efgartigimod injection for myositis
This study tests the long-term safety and effectiveness of a subcutaneous (under-the-skin) version of efgartigimod for adults with active idiopathic inflammatory myopathy. It is for people who have already completed an earlier study of this medicine.
Beverly Hills, CaliforniaAges 18 years+ - NCT05895786RecruitingPhase 3
Study drug for active dermatomyositis or polymyositis
This Phase 3 trial tests how an investigational medicine (PF-06823859) works in adults with active dermatomyositis or polymyositis. It aims to improve disease control by targeting the immune system, but you must meet several safety and diagnosis requirements.
Orange, CaliforniaAges 18 years+ - NCT06308978RecruitingPhase 1
Study of FT819 for B-cell autoimmune diseases
This trial tests a new cell therapy, FT819, for people with certain autoimmune diseases like lupus, vasculitis, myositis, or scleroderma that haven't improved with at least two previous treatments. The goal is to see if it can help control the disease.
Beverly Hills, CaliforniaAges 12–70 - NCT06925542RecruitingPhase 1
Study of CTX112 for adults with autoimmune disease
This trial tests an experimental cell therapy called CTX112 for people with lupus, scleroderma, or inflammatory myositis that hasn't responded well to standard treatments. The goal is to see if it's safe and if it can help control the disease.
La Jolla, CaliforniaAges 18–70 - NCT06991114RecruitingPhase 2
AlloNK and rituximab for relapsing rheumatologic diseases
This trial tests a new natural killer (NK) cell therapy called AlloNK given with rituximab for people with certain autoimmune diseases (rheumatoid arthritis, Sjögren's disease, inflammatory myopathies, or systemic sclerosis) that have not responded well to standard treatments. The goal is to see if this combination can better control the disease.

What taking part in a myositis study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there myositis clinical trials in California?
- Yes. We're currently tracking 7 recruiting myositis studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a myositis study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a myositis trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New myositis studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
