- NCT03926338RecruitingPhase 2
Before-surgery immunotherapy for MSI-H or dMMR colon cancer

Guangzhou, GuangdongAges 18–75 - NCT06925243RecruitingPhase 3
Apatinib, Sintilimab, and Chemo for Intestinal Gastric Cancer
This phase 3 trial tests adding the targeted drug apatinib to a standard combination of sintilimab (immunotherapy) and chemotherapy (SOX regimen) given before surgery for a specific type of stomach or gastroesophageal junction cancer (intestinal type, HER2-negative). The goal is to see if the three-drug combination works better than the two-drug combination in shrinking the tumor and improving outcomes before surgery.
Lanzhou, GansuAges 18–75 - NCT05547529RecruitingPhase 3
Chemo and radiation before surgery versus chemo alone for esophageal cancer
This trial studies whether adding radiation to chemotherapy before surgery works better for people with operable (resectable) squamous cell esophageal cancer. It aims to improve outcomes by comparing two different treatment plans before the operation.
MoscowAges 18–70 - NCT05582265RecruitingPhase 3
Study immune drug plus chemo before surgery versus surgery first
This Phase 3 trial compares two treatment plans for stage III/IVA head and neck squamous cell cancer (HNSCC). One plan uses an immune drug with chemotherapy before surgery; the other goes straight to surgery first, to see which approach works better.
Guanzhou, GuangdongAges 18–80 - NCT06323369RecruitingPhase 2
Tislelizumab plus chemo before surgery vs surgery alone for head and neck cancer
This trial tests whether giving tislelizumab (an immunotherapy) with chemotherapy before surgery works better than surgery alone for people with head and neck cancer that has not spread to lymph nodes. It's for cancers that can be removed with surgery, and the goal is to see if the pre-surgery treatment improves outcomes.
Guangzhou, YuexiuAges 18–75 - NCT06642428Recruiting

Cadonilimab with chemo for stomach cancer
This trial tests a new combination of immunotherapy (cadonilimab) and chemotherapy before and after surgery for a specific type of advanced stomach or gastroesophageal junction cancer. It aims to see if adding this immunotherapy helps shrink tumors and improve outcomes.

Neoadjuvant therapy with trastuzumab rezetecan and toripalimab for HR+/HER2-low breast cancer
This trial tests a combination of two drugs (trastuzumab rezetecan and toripalimab) given before surgery to treat a specific type of breast cancer that is hormone-receptor-positive and HER2-low. It aims to see if this treatment can improve outcomes for patients who have not had prior cancer treatment.
HarbinAges 18–70 - NCT06317558Recruiting
Real-world study of immunotherapy before surgery for lung cancer
This study looks at how well immunotherapy given before surgery works for non-small cell lung cancer. It aims to help doctors understand real-world outcomes for patients who receive this treatment.
Beijing, Beijing MunicipalityAges 18–85 - NCT04836156RecruitingPhase 1/Phase 2
Personalized pre-surgery treatment for HER2-negative early breast cancer
This study tests a treatment plan chosen using lab drug testing on a patient’s tumor (in a dish). It may help improve outcomes for people with early breast cancer that is HER2-negative by matching therapy to what the tumor seems sensitive to.
BeijingAges 18–75 - NCT06766578RecruitingPhase 2
Low-dose radiation plus immunotherapy and chemo before gastric cancer surgery
This trial tests a new combination of low-dose radiation, an immunotherapy drug (tirelizumab), and chemotherapy (SOX) given before surgery for locally advanced gastric or gastroesophageal junction cancer. The goal is to see if this approach can shrink tumors more effectively.
Jinan, ShandongAges 18–75 - NCT06734702RecruitingPhase 3
Immunotherapy before chemo-radiation for advanced lung cancer
This trial tests a new approach for people with stage III lung cancer that cannot be removed with surgery. You would receive immunotherapy (to help your immune system fight cancer) plus chemotherapy first, then standard chemo-radiation, and finally more immunotherapy. The goal is to see if this sequence works better than standard treatment.
Guangzhou, GuangdongAges 18–75 - NCT03734952Recruiting
Radiation after esophagus surgery for stage II–III cancer
This study looks at whether giving radiation after surgery (after chemo and radiation before surgery) can improve outcomes for people with squamous cell esophagus cancer in the chest. You may be considered if you are well enough for treatment and your cancer has not spread.
Fuzhou, FujianAges 18–65 - NCT07346248Enrolling by invitation
Complications after pre-surgery treatment for advanced rectal cancer
This study looks at complications that happen after surgery in patients with advanced rectal cancer who got radiation or chemo-radiation before their operation. Researchers want to learn how different pre-surgery treatments affect recovery.
Rozzano, MilanAges 18 years+ - NCT06908668RecruitingPhase 2
Adebrelimab plus chemo with or without radiation before breast cancer surgery
This trial tests adding a drug called adebrelimab to standard chemotherapy and possibly radiation, given before surgery for breast cancer that is HER2-negative and locally advanced. The goal is to see if this combination helps shrink tumors more effectively, potentially allowing for breast-conserving surgery.
BeijingAges 18–70 - NCT06832904RecruitingPhase 2
Chemo plus two targeted drugs before surgery for HER2+ breast cancer
This trial tests whether giving a combination of two targeted drugs (pyrotinib and trastuzumab) along with standard chemotherapy before surgery can work better for HER2-positive breast cancer. It is for women whose cancer has not spread to distant organs and who have not yet had treatment for their cancer.
HangzhouAges 18–75 - NCT06798376Recruiting
Immunotherapy plus chemo before stomach cancer surgery
This trial tests combining immunotherapy (PD-1 blockers) with chemotherapy before surgery for advanced stomach cancer. The goal is to find the best number of treatment cycles to shrink the tumor and improve surgery results.
BeijingAges 18–90 - NCT04138212RecruitingPhase 3

Common questions
- Are there clinical trials for neoadjuvant?
- Yes. Clin2 currently lists 908 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.
