Tislelizumab plus chemo before surgery for MSS rectal cancer
This trial tests a combination of an immunotherapy drug (tislelizumab) plus chemotherapy before surgery for people with a specific type of rectal cancer that has not spread to other organs. The goal is to see if this approach can shrink the tumor more effectively than standard treatment.
Nanning, GuangxiAges 18 years+ - NCT06259123RecruitingPhase 2
PSMA Radiotherapy Before Prostate Cancer Surgery
This trial tests a radioactive drug (PSMA-RLT) given before surgery for prostate cancer that has spread to a few spots. It aims to see if this treatment can stop the cancer from growing further.
ViennaAges 18–75 - NCT07872722RecruitingPhase 2
Study of two immunotherapies plus chemotherapy before surgery for stomach cancer
This trial tests a new approach for stomach cancer that hasn't spread. You'd get a combination of an investigational drug targeting a specific protein on cancer cells, an immunotherapy that helps your immune system fight cancer, and standard chemotherapy before surgery. The goal is to see if this makes the tumor shrink more and improves outcomes.
SaitamaAges 18 years+ - NCT05377658RecruitingPhase 2
AK104 with chemo before and after surgery for lung cancer
This trial studies AK104 along with chemotherapy given before surgery and after surgery for people with resectable (operable) stage II to IIIA non-small cell lung cancer. It aims to improve treatment effectiveness by shrinking the tumor before surgery and helping prevent it from coming back afterward.
Zhengzhou, HenanAges 18–75 - NCT05999149RecruitingPhase 3
Famitinib plus chemo and immunotherapy before breast cancer surgery
This trial tests whether adding a targeted therapy pill (famitinib) to standard chemo plus an immunotherapy (camrelizumab) can shrink triple negative breast cancer before surgery. It may help people with earlier-stage disease who have not had certain prior treatments.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT07855627Recruiting
Predicting lymphedema risk before surgery
This study looks at whether a simple measurement taken before surgery can help predict if you might develop lymphedema (arm swelling) after treatment. It is for women with newly diagnosed inflammatory breast cancer who are planning to have standard treatments.
Houston, TexasAges 18 years+ - NCT07854600RecruitingPhase 2
Ivonescimab plus chemotherapy before surgery for bile duct cancer
This trial tests a new drug combination given before surgery to shrink bile duct cancer tumors, potentially making surgery more successful. It is for patients whose cancer is locally advanced or has spread to only a few places.

Ablation with immunotherapy and chemo before lung cancer surgery
This study tests a new approach for people with early-stage lung cancer that can be removed with surgery. Before surgery, patients receive a treatment called cryo-thermal ablation to freeze and heat the tumor, along with an immunotherapy drug (toripalimab) and chemotherapy. The goal is to see if this combination shrinks tumors and improves outcomes after surgery.

Common questions
- Are there clinical trials for neoadjuvant?
- Yes. Clin2 currently lists 882 recruiting neoadjuvant 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 neoadjuvant 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 neoadjuvant 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.
