Recruiting studies in California
- NCT06297226RecruitingPhase 2
CAR T cell therapy for multiple myeloma
This trial tests a new CAR T cell therapy (arlocabtagene autoleucel) that targets a protein called GPRC5D on myeloma cells. It is for people whose multiple myeloma has come back or is not responding after trying at least four different types of treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT06121843RecruitingPhase 1
Study of CAR-T cell therapy in combinations for multiple myeloma

Duarte, CaliforniaAges 18 years+ - NCT05730036RecruitingPhase 3
Linvoseltamab vs standard treatment for relapsed myeloma
This trial compares linvoseltamab against a standard combination (elotuzumab + pomalidomide + dexamethasone) in adults with multiple myeloma that has returned or not responded. It aims to find out whether linvoseltamab works better and is safe for people who have already had some myeloma treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT04910568RecruitingPhase 1
Study of cevostamab for people with returning or hard-to-treat myeloma
This trial tests a new drug called cevostamab for people whose multiple myeloma has come back or stopped responding to treatment. It aims to see if the drug is safe and how well it works.
Irvine, CaliforniaAges 18 years+ - NCT05332054Enrolling by invitation

Comparing ronde-cel to standard CAR T-cell therapy for large B-cell lymphoma
This trial tests a new treatment called ronde-cel against the usual CAR T-cell therapy for people with large B-cell lymphoma that has come back or not responded to initial treatment. The goal is to see if ronde-cel works better.

PEEL-224 with chemo for pediatric solid tumors
This trial tests a new drug called PEEL-224 combined with two chemotherapy medicines (vincristine and temozolomide) for children and young adults with certain solid tumors that have come back or not responded to treatment. It aims to see if this combination is safe and works against the cancer.
Los Angeles, CaliforniaAges 1–30 - NCT06173518RecruitingPhase 1
CAR T-cell therapy for children with B-cell leukemia or lymphoma
This trial tests a CAR T-cell therapy that targets CD19 on cancer cells. It is for children whose B-cell acute lymphoblastic leukemia or aggressive B-cell non-Hodgkin lymphoma has come back or not responded to other treatments.

Duarte, CaliforniaAges 18 years+ - NCT04047628RecruitingPhase 3
MS patients with active relapsing disease comparing two treatment plans
This Phase 3 study compares the best standard MS treatment (chosen by your doctors) versus an approach called autologous hematopoietic stem cell transplant (AHSCT) for people with highly active, treatment-resistant relapsing multiple sclerosis. It aims to see which option controls MS disease activity better and keeps you safer over time.
Palo Alto, CaliforniaAges 18–55 - NCT06433752Recruiting
Study of BRIUMVI for relapsing multiple sclerosis

What taking part in a relapsed or refractory multiple myeloma 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 relapsed or refractory multiple myeloma clinical trials in California?
- Yes. We're currently tracking 198 recruiting relapsed or refractory multiple myeloma 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 relapsed or refractory multiple myeloma 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 relapsed or refractory multiple myeloma 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.
