AmiensAges 18 years+ - NCT07388524RecruitingPhase 3
Testing atezolizumab after surgery for early stage lung cancer
This trial tests if the immunotherapy drug atezolizumab can prevent early stage non-small cell lung cancer from coming back after surgery. It is for people whose tumors have high levels of a protein called PD-L1 (50% or more) and do not have certain gene changes (EGFR or ALK).
Newark, DelawareAges 18 years+ - NCT06451029Recruiting

Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT05920343RecruitingPhase 2/Phase 3
Preventing blood clots in genitourinary cancer with rivaroxaban
This trial tests whether rivaroxaban, a blood thinner pill, can help prevent dangerous blood clots in people with certain genitourinary cancers who are starting cancer treatment. It may lower clot risk, but it also has bleeding-risk tradeoffs that the study will monitor closely.
Ottawa, OntarioAges 18 years+ - NCT07092111Recruiting
Ear acupuncture to prevent nerve damage from chemotherapy in breast cancer
This trial tests if ear acupuncture can help prevent nerve damage caused by taxane chemotherapy in breast cancer patients. If you are starting 4 rounds of this chemo and have not had nerve issues before, this may be an option for you.
Nanjing, JiangsuAges 18–75 - NCT07233863Recruiting
Lymphovenous bypass for preventing lymphedema in breast cancer
This trial tests a surgery (lymphovenous bypass) to prevent or slow down lymphedema (arm swelling) in breast cancer patients who have already had lymph nodes removed. It may help those with early-stage lymphedema who haven't tried physical therapy yet.
Jakarta, Jakarta Special Capital RegionAges 18 years+ - NCT05432297Recruiting
Exercise program for people getting treatment for head and neck cancer
This trial tests whether a preventive, structured physical activity program can help people during and around curative treatment for head and neck cancers. It aims to see if exercise is safe and beneficial for strength, function, and well-being during radio(±chemo) therapy.
GothenburgAges 18 years+ - NCT07699276RecruitingPhase 2
Steroid-sparing nausea drug combo for high-dose chemo
This trial tests if combining two anti-nausea drugs (olanzapine and palonosetron) can prevent vomiting and nausea without using steroids in people receiving high-dose cisplatin chemotherapy for their first time.
BangkokAges 18 years+ - NCT05316922RecruitingPhase 3
Lowering thyroid hormone during radiation to prevent low thyroid
This study tests whether using treatment to keep thyroid-stimulating signals low during radiation to the thyroid area can help prevent a treatment-related drop in thyroid function in children. It is aimed at kids with certain cancers whose radiation plan includes thyroid tissue.
MilanAges Any age - NCT05557877RecruitingPhase 2
Low-dose aspirin to prevent postpartum breast cancer
This study tests whether taking a low dose of aspirin after childbirth can lower the chance of developing breast cancer later. You may be asked to provide blood, urine, and breast tissue samples so researchers can look for changes that could explain why aspirin may help.
Scottsdale, ArizonaAges 18–45 - NCT05704166RecruitingPhase 2
Pirfenidone to prevent lung injury after breast radiation
This trial tests whether pirfenidone, a medication, can prevent acute lung injury caused by radiation therapy in people with breast cancer. You may be randomly assigned to pirfenidone or a placebo (inactive pill) to see which better protects the lungs during and after radiation.
Fuzhou, FujianAges 18–75 - NCT06341907RecruitingPhase 2/Phase 3
Vaccine and blood test to prevent ovarian cancer return
This trial tests a personalized vaccine for people with epithelial ovarian cancer who still have a small amount of cancer DNA in their blood after surgery. The goal is to see if the vaccine can help stop the cancer from coming back.
Wenzhou, ZhejiangAges 18–70 - NCT07127003Recruiting
Surgical bypass to prevent arm swelling after lymph node removal
This study tests a surgical bypass (called ILR) to prevent arm swelling (lymphedema) after removing lymph nodes from under the arm during breast cancer surgery. The goal is to see if this extra step helps keep your arm healthy.
Tampa, FloridaAges 18–75 - NCT06268665RecruitingPhase 2

Chicago, IllinoisAges 65 years+ - NCT05530655RecruitingEarly Phase 1
Finding the best lisinopril dose to prevent urine side effects
This early study tests which dose of lisinopril works best to help prevent urinary toxicity (urine/burning/urinary side effects) after radiation treatment for prostate cancer. If it’s effective for you, it could make radiation easier to tolerate.

Common questions
- Are there clinical trials for cancer prevention?
- Yes. Clin2 currently lists 291 recruiting cancer prevention studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cancer prevention trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cancer prevention trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
