Study of immunotherapy plus targeted therapy and chemo before surgery for lung cancer
This trial tests a combination of immunotherapy (adebrelimab), a targeted therapy (apatinib), and chemotherapy given before surgery for people with limited-stage small cell lung cancer. The goal is to see if this treatment shrinks the tumor enough to make surgery more effective and to study markers that might predict response.
Hangzhou, ZhejiangAges 18–75 - NCT06463262Recruiting
Personalized markers for chordoma before surgery and radiation
This trial tests whether analyzing blood and tumor samples before and after radiation and surgery can help find personalized markers for chordoma. It is for patients with chordoma of the skull base, spine, or sacrum who will receive radiation before surgery.
Baltimore, MarylandAges 18 years+ - NCT06461910RecruitingPhase 2
Immunotherapy, thymalfasin, and chemo before surgery for stomach cancer
This trial is testing a combination of three medicines—an immunotherapy (anti-PD-1), an immune booster (thymalfasin), and a chemotherapy regimen (SOX)—given before surgery to shrink stage III stomach or gastroesophageal junction cancer and improve outcomes.
Nanjing, JiangsuAges 18–75 - NCT04138719RecruitingPhase 2
Test two chemotherapy combos before breast surgery for triple-negative cancer
This trial compares two different chemotherapy combinations given before surgery (neoadjuvant therapy) for people with triple-negative breast cancer. It looks to see which drug combination works better to control the cancer before and around the time of the operation.
Shijiazhuang, HebeiAges 18–70 - NCT06441890RecruitingPhase 2
Personalized chemo before breast cancer surgery
This trial tests whether giving chemotherapy before surgery, guided by the genetic profile of your tumor, can improve outcomes for a specific type of HER2-positive breast cancer. It aims to tailor treatment to each person's cancer biology.
Chicago, IllinoisAges 18 years+ - NCT06449313RecruitingPhase 2
Immunotherapy before lung cancer surgery for stage 3 disease
This trial tests whether giving chemotherapy plus immunotherapy before surgery can help shrink stage 3 lung cancer and improve outcomes. The goal is to make the tumor easier to remove and possibly lower the chance of it coming back.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06423326RecruitingPhase 2
Chemotherapy before surgery for pancreatic cancer
This trial tests a combination of three chemotherapy drugs given before surgery for pancreatic cancer that is removable or borderline removable. The goal is to shrink the tumor to make surgery more successful.
Washington D.C., District of ColumbiaAges 18 years+ - NCT06435260RecruitingPhase 2
Short radiation, chemo, and immunotherapy before pancreas cancer surgery
This trial tests a short course of radiation combined with chemo and the immunotherapy drug camrelizumab before surgery for pancreatic cancer. It aims to shrink tumor to make removal easier and improve outcomes.
Shijiazhuang, HebeiAges 18–75 - NCT06435351RecruitingEarly Phase 1

Tampa, FloridaAges 18 years+ - NCT06437977RecruitingPhase 3
Pre-surgery treatment with radiation, immunotherapy, and chemo for stage II-III NSCLC
This trial tests whether combining radiation, an immunotherapy drug (toripalimab), and chemotherapy before surgery can help shrink tumors and improve outcomes in people with resectable stage II to III non-small cell lung cancer. It aims to see if this approach works better than standard chemotherapy alone.

Philadelphia, PennsylvaniaAges 18 years+ - NCT06417190RecruitingPhase 2
Bladder preservation trial for muscle-invasive bladder cancer with variant histology
This trial tests a bladder-sparing approach for people with muscle-invasive bladder cancer that has a variant histology type. The goal is to avoid removing the bladder by using a combination of treatments.

Common questions
- Are there clinical trials for neoadjuvant?
- Yes. Clin2 currently lists 881 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.
