Birmingham, AlabamaAges 18 years+ - NCT07262957RecruitingPhase 4
Preventing complications after pancreatic surgery with a drug bundle
This trial tests whether giving a combination of three treatments—hydrocortisone (a steroid), octreotide (a drug that reduces digestive fluids), and a tissue patch—before and during pancreatic surgery can help prevent complications. It is for people with a very small pancreatic duct (3 mm or less) who are scheduled for pancreatic surgery.
AmsterdamAges 18 years+ - NCT07187908RecruitingPhase 2
Study of Efbemalenograstim Alfa to prevent low white blood cell counts in cancer patients
This trial tests if a drug called Efbemalenograstim Alfa can help prevent a serious drop in white blood cells (febrile neutropenia) during chemotherapy. It is for patients with solid tumors who have a high or intermediate risk of this condition.
Zhengzhou, HenanAges 18–75 - NCT06860542RecruitingPhase 2
Inhaled steroid to prevent lung inflammation from returning after immunotherapy
This trial tests whether using an inhaled steroid (budesonide) can help prevent lung inflammation (pneumonitis) from coming back in people who have had it caused by immunotherapy cancer treatment. It may be an option for patients who need extra support after their first bout of this side effect.
Calgary, AlbertaAges 18 years+ - NCT06080880Recruiting
Testing weekly vs every 3 weeks ondansetron for chemo nausea
This trial compares two schedules of ondansetron (a nausea prevention drug) in people getting cisplatin chemotherapy plus a PD-1 inhibitor. It aims to find which dosing schedule works best to prevent nausea and vomiting.

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.
