Chemo-immunotherapy and cognition in head and neck cancer
This trial is studying whether a combination of chemotherapy (carboplatin and paclitaxel) and an immunotherapy drug (anti-PD-1) affects memory and thinking in people with head and neck cancer that can be removed with surgery. Researchers want to see if these treatments cause any cognitive changes.

Total neoadjuvant therapy vs surgery for rectal cancer
This trial tests whether a full course of chemotherapy and radiation before any surgery (called total neoadjuvant therapy) can help you avoid surgery and preserve your rectum. It is for people with a specific early stage of rectal cancer that has not spread.
VilniusAges 18 years+ - NCT06977893RecruitingPhase 3
Chemo and immunotherapy for HR+ breast cancer before surgery
This trial tests whether adding the immunotherapy drug toripalimab to chemotherapy before surgery helps women with a certain type of breast cancer (HR+, HER2-). It aims to see if this combination works better than chemotherapy alone.
HangzhouAges 18–75 - NCT07016724RecruitingPhase 2
Study of radiation and chemo with cadonilizumab for esophageal cancer
This trial tests combining radiation, chemotherapy, and the drug cadonilizumab before surgery for locally advanced esophageal squamous cell cancer. It aims to shrink the tumor and improve treatment outcomes.
Zhengzhou, HenanAges 18–75 - NCT07086469RecruitingPhase 2
Surufatinib plus chemo-immunotherapy before chemoradiation for advanced esophageal cancer
This trial tests a new combination of treatments for people with advanced esophageal cancer that can't be removed by surgery. It uses a targeted therapy called surufatinib along with chemo-immunotherapy and radiation to see if it can shrink the tumor before further treatment.
Guangzhou, GuangdongAges 18–80 - NCT07121374RecruitingPhase 1/Phase 2
Chemotherapy and immunotherapy before possible surgery for mesothelioma
This trial tests whether giving chemotherapy and immunotherapy before planned surgery can make inoperable pleural mesothelioma operable. It is for people with a specific type of mesothelioma (epithelioid) that cannot be removed right away, to see if the treatment shrinks the tumor enough for surgery later.
Edegem, AntwerpAges 18 years+ - NCT07165847RecruitingPhase 2
Combination therapy before surgery for gastric cancer
This trial tests a combination of radiation, chemotherapy, and two immunotherapy drugs before surgery for people with resectable gastric or gastroesophageal junction cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.

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.
