Wuxi, JiangsuAges 15–75 - NCT06430541RecruitingPhase 1
Psilocybin therapy for fear of cancer recurrence
This trial tests if psilocybin-assisted therapy can help reduce the intense worry that cancer might come back. It is for people who have finished their main treatments for early-stage breast cancer or advanced ovarian cancer.
Aurora, ColoradoAges 21 years+ - NCT06150664RecruitingPhase 1
Study of CTX-8371 for advanced cancers no longer helped by standard therapy
This trial tests a new drug called CTX-8371 for people with advanced cancers (melanoma, head and neck, lung, triple-negative breast, or Hodgkin lymphoma) that have stopped responding to standard treatments, especially immunotherapy. It is a first-in-human study, meaning doctors are learning if the drug is safe and how well it works.

PET/MRI scan for PR-positive breast cancer before surgery
This trial tests a new PET/MRI scan (using a special tracer called 18F-FFNP) to see how it images progesterone-receptor-positive breast cancer before surgery. You would get the scan and then have your planned surgery.
Madison, WisconsinAges 18 years+ - NCT01174121RecruitingPhase 2
Immunotherapy made from your tumor-fighting immune cells
This trial tests a treatment made from your own immune cells (called tumor-infiltrating lymphocytes, or TILs) for certain metastatic cancers. It’s designed for people whose cancer has not responded to standard treatments and who can safely provide a small tumor sample for cell-making.
Bethesda, MarylandAges 18–72 - NCT04345081Recruiting
Compare two breast surgery skin-sparing methods and recovery
This trial compares two types of mastectomy (with skin and nipple options) and implant reconstruction to see which gives better cosmetic results, comfort, and satisfaction. You may help doctors learn which approach leads to a better quality of life after surgery.
BudapestAges 18–65 - NCT06731894RecruitingPhase 2
Cannabis for nerve pain after chemotherapy in breast and colon cancer survivors
This trial tests whether a cannabis-based product can reduce nerve damage (neuropathy) caused by chemotherapy in people who have finished treatment for breast or colon cancer. It focuses on survivors who still have pain, numbness, or tingling in their hands or feet.

This trial tests if adding trilaciclib to standard chemotherapy after surgery can help people with hormone receptor-negative breast cancer. It aims to reduce side effects and improve treatment outcomes.
Guangzhou, GangdongAges 18 years+ - NCT05440227RecruitingPhase 2
PG2 shots to reduce moderate to severe breast cancer fatigue
This Phase 2 trial tests whether PG2 injections can safely reduce moderate to severe fatigue in people receiving chemotherapy for locally advanced, recurrent, or metastatic breast cancer. If you qualify, you may be asked to complete questionnaires and follow study plans for about 8 weeks.
TaipeiAges 20 years+ - NCT06629233Enrolling by invitation
New immunotherapy targets for estrogen-receptor positive breast cancer
This trial tests a new technique to find unique targets on breast cancer cells that could be used for future immunotherapies. It focuses on women with estrogen-receptor positive primary breast cancer.
Ghent, East-FlandersAges 18 years+ - NCT06369831RecruitingPhase 2
Imaging test for HER2 in metastatic cancer
This trial uses a special imaging scan to see if your cancer has HER2 on its surface, which could help decide if HER2-targeted treatment might work for you. It's for people with metastatic breast cancer or other solid tumors that have spread.
Innsbruck, TyrolAges 18 years+ - NCT04222413RecruitingPhase 1
Study of metarrestin for advanced solid tumors
This study tests an experimental drug called metarrestin for people with solid tumors that have spread or come back after standard treatment. It may help by targeting a protein involved in cancer cell growth.
Fairway, KansasAges 12–120 - NCT05107674RecruitingPhase 1
Early drug study for advanced cancers that have limited options
This Phase 1 study tests NX-1607 in adults with advanced cancers that are hard to treat with standard care. It focuses on safety and early signs of how well the drug may work in specific cancer types.
Duarte, CaliforniaAges 18 years+ - NCT07356531Recruiting
Thermosensitive Embolic Agent for Liver Cancer TACE
This trial tests a new heat-sensitive embolic agent used during TACE (a procedure that blocks blood flow to tumors and delivers chemotherapy directly to the liver) for primary liver cancer. It aims to see if the agent is safe and effective for patients who need TACE treatment.
Hefei, AnhuiAges 18–80 - NCT07116161Recruiting
Exercise and counseling for fatigue in female breast cancer patients
This trial tests if combining exercise with cognitive behavioral therapy (counseling) can help reduce fatigue in women with breast cancer. You may be able to join if you have completed your initial treatments and still feel tired.
SingaporeAges 21 years+ - NCT06833255Recruiting
Support Program for Black Women Breast Cancer Survivors
This program pairs Black women who have completed breast cancer treatment with support to help them transition into survivorship. It offers mentorship based on how recently you finished treatment, with priority for those who had limited support or who identify as African American.

Study of a new treatment for advanced cancers with a specific gene change
This trial tests a new type of therapy (NT-175) for people with certain advanced cancers that have a specific genetic change. It might help if your tumor has the TP53 R175H mutation and you have the HLA-A*02:01 immune marker.
Gilbert, ArizonaAges 18 years+ - NCT06817694Recruiting
CBT for fear of cancer returning in BRCA1/2 women
This trial tests if cognitive behavioral therapy can reduce fear of cancer recurrence in women with BRCA1/2 mutations who have finished treatment for breast or ovarian cancer. It aims to help you cope with worries about cancer coming back.
Québec, QuebecAges 18 years+ - NCT07297667RecruitingPhase 1
CAR T-cell therapy for certain advanced solid tumors
This trial tests a new treatment called GCAR1, which uses your own immune cells (T-cells) to find and attack cancer cells that have a specific marker called GPNMB. It is for people with certain advanced solid tumors that have not responded to other treatments. The goal is to see if this therapy can help shrink or control the tumor.
Calgary, AlbertaAges 15 years+ - NCT07169994RecruitingPhase 1/Phase 2
Testing YL202 with other cancer treatments for advanced solid tumors
This trial is testing a new drug called YL202 in combination with other anti-cancer treatments for people with advanced solid tumors that have not responded to standard therapy. The goal is to see if this combination can shrink tumors or slow their growth.

Imaging removed tissue during cancer surgery
This study tests a high-resolution PET-CT scanner that takes pictures of tissue removed during surgery to help doctors see if all the cancer has been removed. You might qualify if you are having surgery for a range of cancers including breast, prostate, thyroid, skin, gastrointestinal, or brain tumors.
Ghent, Oost VlaanderenAges 18 years+ - NCT06450873RecruitingPhase 2

Common questions
- Are there clinical trials for primary breast cancer?
- Yes. Clin2 currently lists 711 recruiting primary breast cancer 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 primary breast cancer 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 primary breast cancer 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.
