Recruiting studies in California
- NCT05941520RecruitingPhase 2
Acolbifene vs low-dose tamoxifen to prevent breast cancer
This Phase 2 trial compares acolbifene and low-dose tamoxifen to see which better lowers breast cancer risk in premenopausal women at high risk. You would be followed with health visits, blood tests, and a breast tissue sampling procedure.
Duarte, CaliforniaAges 35 years+ - NCT05218044Recruiting
Cryoablation for small DCIS instead of breast surgery
This trial studies whether cryoablation (freezing abnormal breast tissue) can treat DCIS, a non-invasive early breast cancer, without surgical lumpectomy. It aims to see if a less invasive approach could help people with small, limited-area DCIS while avoiding some effects of surgery.
Glendale, CaliforniaAges 18 years+ - NCT06075953RecruitingPhase 2
Testing Active Surveillance for Hormone-Positive DCIS After Surgery
This trial tests whether active surveillance (close monitoring) is a good option for certain patients with hormone-positive DCIS who have positive surgical margins after initial surgery. You would receive no immediate additional treatment—just regular imaging and check-ups.
Berkeley, CaliforniaAges 18 years+ - NCT03909282Recruiting
Surgery now versus radiation then delayed surgery for DCIS
This trial compares two approaches for ductal carcinoma in situ (DCIS): having surgery first versus getting radiation first and then having surgery later. It aims to see which plan controls DCIS better while affecting treatment timing and outcomes.
Stanford, CaliforniaAges 18 years+ - NCT06022029RecruitingPhase 1
Study of injected ONM-501 alone or with cemiplimab for advanced cancers
This trial tests an injected study drug (ONM-501) alone or with another drug (cemiplimab) for people with advanced solid tumors or lymphomas that haven't responded to other treatments. It aims to find a safe dose and see if the combination helps shrink or control the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT07480356RecruitingPhase 3
Testing a new bladder cancer treatment (TARA-002) vs standard chemo
This trial compares a new medicine called TARA-002, given directly into the bladder, to the doctor's choice of standard chemotherapy. It is for people with a high-grade, non-muscle invasive bladder cancer that has not been treated with BCG or has not had BCG recently.
Bakersfield, CaliforniaAges 18 years+ - NCT04752722RecruitingPhase 1/Phase 2
Gene therapy for bladder cancer that came back after BCG
This study tests a new gene therapy (EG-70) given directly into the bladder for people with a high-risk bladder cancer called NMIBC. It may be an option if BCG treatment stopped working, or if you cannot have or choose not to have bladder removal surgery.
Irvine, CaliforniaAges 18 years+ - NCT06545955RecruitingPhase 3
Gene therapy study for high-grade bladder cancer not responding to BCG
This trial tests a gene therapy called nadofaragene firadenovec, given directly into the bladder, either alone or with chemo or immunotherapy. It's for people with high-grade bladder cancer that hasn't gone away after BCG treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT03448926Recruiting
DCIS test registry to guide radiation and drug decisions
This study collects information from people with breast ductal carcinoma in situ (DCIS) to see how a specific lab test (DCISionRT) may help predict who benefits from radiation and/or certain medications. Your results and clinical details are gathered during routine care, not necessarily to change treatment right away.
San Mateo, CaliforniaAges 30–85 - NCT04603209Recruiting
Check-in registry for radiation during breast-conserving surgery
This registry study tracks people with early-stage, single-area breast cancer to understand outcomes when radiation is given during breast-conserving surgery. It may help doctors improve treatment planning for patients like you.
Santa Monica, CaliforniaAges 18 years+ - NCT04712851RecruitingPhase 2
Pembrolizumab for abnormal cells on the cervix
This trial tests pembrolizumab (an immune treatment) to see if it can treat high-grade abnormal cells of the cervix (CIN 2/3 or carcinoma in situ). You may need biopsies during the study and a planned procedure after about 24 weeks to remove or sample the cervix tissue.
Los Angeles, CaliforniaAges 21 years+ - NCT06833073RecruitingPhase 2
Study of an mRNA vaccine and BCG for bladder cancer
This trial tests an experimental mRNA vaccine (V940) combined with BCG therapy for people with high-risk non-muscle invasive bladder cancer that hasn't spread. It aims to see if the vaccine can help the immune system better fight the cancer.
Torrance, CaliforniaAges 18 years+ - NCT02620852Recruiting
Wisdom Study: Women’s breast cancer screening decisions
This study looks at how to decide the best breast cancer screening (like mammograms) based on your personal risk. It may help by testing a smarter way to match screening to your risk level.
Los Angeles, CaliforniaAges 30–74 - NCT02402244Recruiting
Caring registry study for children and young people with cancer
This study keeps a careful record of children, teens, and young adults with cancer (and some related growths) and may follow them over time. It helps researchers better track outcomes and future contact so care can improve.
Downey, CaliforniaAges Up to 25 years

What taking part in a carcinoma in situ 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 carcinoma in situ clinical trials in California?
- Yes. We're currently tracking 14 recruiting carcinoma in situ 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 carcinoma in situ 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 carcinoma in situ 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 carcinoma in situ 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.
