Pre-surgery chemotherapy and immunotherapy for operable pancreatic cancer
This Phase 2 trial tests giving chemotherapy plus pembrolizumab (an immunotherapy) before surgery, to shrink or control potentially removable pancreatic cancer. The goal is to improve outcomes while making sure the cancer can still be safely removed by surgery.
Houston, TexasAges 18 years+ - NCT05140746Recruiting
Predicting how well chemotherapy works before stomach surgery
This study looks for ways to predict whether neoadjuvant chemotherapy (chemo given before surgery) will work well in people with locally advanced stomach cancer. It may help doctors choose the best treatment plan sooner based on your test results.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05148767RecruitingPhase 4
UGT1A1-guided irinotecan for locally advanced rectal cancer
This trial studies whether adjusting irinotecan treatment based on a person’s UGT1A1 gene test can improve outcomes for locally advanced rectal cancer. It focuses on people who are about to start (or continue) chemoradiation and do not have cancer spread to distant organs.
Hangzhou, ZhejiangAges 18–75 - NCT05159193RecruitingPhase 3
Pre-surgery chemotherapy and antibodies for HER2 breast cancer
This phase 3 trial compares two pre-surgery treatment plans for people with HER2-positive invasive breast cancer that has spread to nearby lymph nodes. It aims to see which plan works better to shrink the tumor before surgery and improve outcomes.
Guandong, GuangdongAges 18–70 - NCT05167487Recruiting
Study of treatment effects after chemotherapy and surgery for lung cancer
This trial looks at how lung tumors respond after chemotherapy given before surgery in people with stage IIIA non-small cell lung cancer (NSCLC). It may help doctors understand which past treatments lead to better results, since it uses medical records from approved clinical cases.
A Coruña, A CoruñaAges 18 years+ - NCT05173272RecruitingPhase 3
Immunotherapy plus chemo, then radiation, for advanced cervical cancer
This study tests whether adding immunotherapy to chemotherapy, then giving chemotherapy together with radiation, works better for advanced cervical cancer. It aims to improve cancer control and help people live longer, without major safety issues.
Chengdu, SichuanAges 18 years+ - NCT05184803RecruitingPhase 2
Pre-surgery chemo for advanced stomach cancer with lymph spread
This Phase 2 study tests a combination chemotherapy regimen given before surgery for stomach cancer that cannot be fully removed (unresectable), including spread to lymph nodes. The goal is to shrink the cancer and improve control with a well-known set of medicines given in a specific order.
Seoul, SeoulAges 19 years+ - NCT05197322RecruitingPhase 2
Pembrolizumab before surgery for MMR-deficient colon or rectal cancer
This trial tests pembrolizumab (an immunotherapy medicine) given before curative surgery in people with certain MMR-deficient colon or rectal cancers. It aims to shrink or control the cancer so surgery can be done more effectively, and to see if outcomes improve compared with standard care.
CambridgeAges 18 years+ - NCT05200260RecruitingPhase 2
Surgery plus maintenance medicines for advanced ovarian cancer
This trial checks whether having surgery to remove as much tumor as possible, followed by ongoing targeted treatment, helps people with advanced ovarian (and related) cancers live longer and/or control cancer better. It specifically uses tumor-testing results to match patients and then continues treatment after surgery.
FoshanAges 18 years+ - NCT05201430RecruitingPhase 3
FOLFOXIRI vs CapeOX before surgery for locally advanced rectal cancer
This trial compares two chemotherapy plans given before rectal cancer surgery to see which helps more people and works better for disease control. If you have locally advanced rectal cancer and have not had treatment yet, this study may be an option.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05239546RecruitingPhase 2
Dostarlimab before colon surgery for mismatch-repair–deficient cancer
This study tests dostarlimab given before surgery for stage II or III colon cancer that has a specific DNA repair defect. It aims to shrink or control the cancer so that some people may be able to skip surgery if the results are good.
Iowa City, IowaAges 18 years+ - NCT05241119Recruiting
Lymph node mapping to guide surgery after chemotherapy
This study tests using a special carbon-based tracing method to help doctors check which lymph nodes to treat during surgery after you finish chemotherapy. It may improve how accurately the surgical plan targets cancer in the armpit (axillary) lymph nodes.
Shenyang, LiaoningAges 18–70 - NCT05263570Recruiting
Real-world treatment planning for stage II–III HR+ HER2+ breast cancer
This trial looks at how well a standard “neoadjuvant” treatment plan works in real-world patients. It is for people newly diagnosed with stage II–III HR+ breast cancer and aims to see whether treatment gives expected outcomes in everyday care.
Shenyang, LiaoningAges 18 years+ - NCT05280314RecruitingPhase 2

This trial tests two immunotherapy medicines given before surgery and again after surgery to help control the cancer and improve outcomes. It studies people with resectable (operable) stage III melanoma or certain stage III/IVA throat cancers.
New Haven, ConnecticutAges 18 years+ - NCT05281003RecruitingPhase 2
Pembrolizumab plus chemo before surgery for esophageal cancer
This trial tests whether giving pembrolizumab (an immune therapy) plus chemotherapy before surgery can improve outcomes for people with locally advanced, operable esophageal squamous cell carcinoma. It may help shrink the tumor and improve the chance of successful surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05284552RecruitingPhase 2
Tinzaparin blood-thinner and biomarkers after ovarian cancer surgery
This Phase 2 study tests whether the blood thinner tinzaparin used after neoadjuvant treatment can change blood markers (“biomarkers”) in people with certain stages of ovarian cancer. It aims to understand if tinzaparin affects the body’s cancer-related signals, which could help future treatment decisions.
Eksjö, EksjöAges 18 years+ - NCT05295212RecruitingPhase 2
Atezolizumab plus chemo before surgery for lung cancer
This trial studies whether adding atezolizumab (an immune medicine) to standard platinum-based chemotherapy before surgery can improve outcomes for operable stage II–IIIB non-small cell lung cancer. The goal is to shrink the tumor and increase the chance the cancer can be removed with better results.
Changsha, HunanAges 18 years+ - NCT05316103Recruiting
Optical biopsy of rectal scars after cancer treatment
This trial tests a targeted “optical biopsy” (using a special light-based exam to sample tissue) to better assess rectal scars after standard chemotherapy and radiation before surgery. It may help surgeons choose the most appropriate way to operate on rectal cancer.
Guangzhou, GuangdongAges 18–80 - NCT05332561RecruitingPhase 2

Common questions
- Are there clinical trials for neoadjuvant?
- Yes. Clin2 currently lists 903 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.
