Malignant Neoplasm clinical trials in California
We’re tracking 108 recruiting malignant neoplasm studies with a site in California — including Phase 1, Phase 1/Phase 2 and Phase 2 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT07283939Recruiting
Testing a tool to adjust chemo doses and reduce treatment delays
This trial tests a computer algorithm called PAGODA that helps doctors adjust chemotherapy doses for people with gastrointestinal cancers. The goal is to prevent unplanned treatment delays while keeping the treatment effective.
Arroyo Grande, CaliforniaAges 18 years+ - NCT03866382RecruitingPhase 2
Immunotherapy plus a targeted drug for rare genitourinary tumors
This Phase 2 study tests whether nivolumab and ipilimumab (immunotherapy drugs) plus cabozantinib (a targeted anti-cancer drug) can shrink or control rare cancers of the urinary/reproductive system that have spread. It may help by boosting the immune system and blocking cancer growth signals at the same time.
Arroyo Grande, CaliforniaAges 18 years+ - NCT04732065RecruitingPhase 1
ONC206 for certain brain tumors in children and young adults
This Phase 1 study tests ONC206, a new targeted medicine, for diffuse midline gliomas (DMG) with a specific gene change (H3K27 altered) and for some other recurrent brain/spinal cord cancers. It is designed to find the right dose and see whether it can control or shrink tumors after initial treatment or when the cancer returns.
San Francisco, CaliforniaAges 2–21 - NCT07741968Recruiting
Online program to ease fear of cancer returning
This study tests an online program designed to help women with advanced or certain types of breast or gynecologic cancer manage their fear of the disease progressing or returning. The program aims to reduce anxiety and improve quality of life.
Arcadia, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
Santa Monica, CaliforniaAges 18 years+ - NCT06655246RecruitingPhase 1
Ziftomenib and imatinib for advanced GIST
This trial tests a new drug, ziftomenib, combined with imatinib for people with advanced or spreading gastrointestinal stromal tumors (GIST) that have a KIT mutation. It may help if your GIST has gotten worse while on imatinib.
Orange, CaliforniaAges 18 years+ - NCT04771130RecruitingPhase 1/Phase 2
Study of BGB-11417 for blood cancers
This early-phase study tests BGB-11417 in people with certain bone-marrow (blood) cancers such as AML, MDS, or MDS/MPN. The goal is to find out how the medicine works and whether it can control the cancer.
Duarte, CaliforniaAges 18 years+ - NCT05786924RecruitingPhase 1/Phase 2
Targeted cancer drug study for RAS/RAF mutation-positive tumors
This Phase 1/2 study tests S241656 (a targeted cancer medicine) in people whose cancers have certain “RAS/RAF” gene changes. It may help shrink tumors or control cancer growth, and also finds the safest dose and best way to use the drug.
San Francisco, CaliforniaAges 18 years+ - NCT05443425RecruitingPhase 1
Leflunomide plus steroids for acute graft-versus-host disease
This early-phase trial tests whether adding leflunomide to standard steroid treatment can better control acute graft-versus-host disease (aGvHD) after a stem cell transplant. It may help reduce the immune reaction that damages the body while keeping treatment safe and manageable.
Duarte, CaliforniaAges 18 years+ - NCT06001788RecruitingPhase 1
Ziftomenib for relapsed or refractory acute myeloid leukemia
This trial tests a new drug combination called ziftomenib for people whose acute myeloid leukemia (AML) has come back or hasn't responded to treatment. Researchers will check how safe it is and what side effects happen.
Los Angeles, CaliforniaAges 18 years+ - NCT05877599RecruitingPhase 1
Study of a new treatment for advanced cancers with a specific gene change
This trial tests a new type of therapy (NT-175) for people with certain advanced cancers that have a specific genetic change. It might help if your tumor has the TP53 R175H mutation and you have the HLA-A*02:01 immune marker.
Duarte, CaliforniaAges 18 years+ - NCT06859424RecruitingPhase 2
Testing a new GVHD prevention method after donor stem cell transplant
This trial tests a new way to prevent graft-versus-host disease (a common side effect of stem cell transplant) using a drug called cyclophosphamide after transplant. It is for adults with certain blood cancers who need a transplant from a partially matched unrelated donor.
Palo Alto, CaliforniaAges 18–66

What taking part in a malignant neoplasm 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 malignant neoplasm clinical trials in California?
- Yes. We're currently tracking 108 recruiting malignant neoplasm 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 malignant neoplasm 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 malignant neoplasm 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 malignant neoplasm 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.
