Recruiting studies
- NCT03017573Recruiting

BordeauxAges 18 years+ - NCT04790253Recruiting
Check brain radiation timing or frequent MRI scans for SCLC
This study compares two ways to follow and treat small-cell lung cancer in the brain: preventive brain radiation versus close monitoring with MRI scans and treatment only if needed. It may help people avoid unnecessary brain treatment or choose the safer timing strategy.
GrazAges 18 years+ - NCT07123649RecruitingPhase 2
Customizing mammogram schedules for older breast cancer survivors
This study looks at how often older breast cancer survivors (80+) should get mammograms. It aims to make screening more personalized so women get the right amount of imaging.
Boston, MassachusettsAges 80 years+ - NCT06516289RecruitingPhase 2
Neoadjuvant treatment for BRCA-mutated HER2-negative breast cancer
This trial tests a combination of two oral medications (HRS-1167 and famitinib) with or without an immunotherapy drug (camrelizumab) before surgery for women with a BRCA gene mutation and HER2-negative breast cancer. It aims to see if these drugs can shrink tumors before surgery.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT06185205RecruitingPhase 2
Accelerated high-dose radiation for early breast cancer
This trial tests a very short, high-dose radiation treatment given directly to the breast after lumpectomy. It aims to make radiation more convenient by finishing in just a few days instead of weeks, possibly with fewer side effects.
Richmond, VirginiaAges 45–79 - NCT06432036RecruitingPhase 1/Phase 2
Y90 Radioembolization for Early Kidney Cancer
This trial tests a treatment called Y90 radioembolization for people with early-stage kidney cancer who cannot have surgery or ablation. Tiny radioactive beads are delivered through a catheter to the tumor's blood supply to destroy it from the inside.
Los Angeles, CaliforniaAges 18 years+ - NCT05890287Recruiting
Chidamide plus hormone therapy after chemotherapy for breast cancer
This trial studies chidamide added to standard hormone (endocrine) therapy to help prevent breast cancer from coming back after initial chemotherapy. It may help by keeping cancer under control for longer in people with HR-positive, HER2-negative breast cancer who respond to first-line treatment.
TianjinAges 18–75 - NCT06240195Recruiting
Study of sacituzumab govitecan for advanced triple-negative breast cancer
This study is testing a drug called sacituzumab govitecan (SG) for people with advanced triple-negative breast cancer who have already had other treatments. The goal is to see how well the drug works and what side effects it causes, using your tumor samples to look for clues (biomarkers).
Rome, RomeAges 18 years+ - NCT07331753Recruiting
Fat grafting with back muscle flap for breast reconstruction
This study tests if combining fat grafting with a muscle flap from the back improves breast reconstruction results after a mastectomy. It may help women who had a mastectomy and are now looking for delayed reconstruction.
Sohag, Sohag GovernorateAges 18 years+ - NCT07214532Recruiting
Using a blood test to guide breast cancer therapy
This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.
Phoenix, ArizonaAges 18 years+ - NCT06910072Enrolling by invitationPhase 2/Phase 3
Chemo and immunotherapy before surgery for triple-negative breast cancer
This trial tests a combination of chemotherapy and two immunotherapy drugs given before surgery for women and men with triple-negative breast cancer. The goal is to see if this approach helps shrink or eliminate the tumor before surgery.
BeijingAges 18–75 - NCT05372614RecruitingPhase 1
Testing trastuzumab deruxtecan and neratinib for HER2-positive cancers
This trial tests a combination of two targeted drugs, trastuzumab deruxtecan (Enhertu) and neratinib, for people with solid tumors that have a HER2 gene change. The goal is to see if the combination is safe and works well for cancers that have not responded to at least one prior treatment.
Duarte, CaliforniaAges 18 years+ - NCT07292246Recruiting
HandX-assisted endoscopic mastectomy study for breast cancer
This trial tests a new, less invasive way to remove breast tissue using a small camera (endoscope) with a device called HandX. It's for women who need a mastectomy for early-stage breast cancer, DCIS, or to reduce high risk, and aims to see if it's safe and works well.
Glyfada, AtticaAges 18 years+ - NCT07017829RecruitingPhase 2
Combination therapy for STK11-mutant lung cancer
This trial tests a new drug (GT103) combined with the approved immunotherapy drug pembrolizumab for people with advanced lung cancer that has a specific genetic change (STK11). The goal is to see if adding GT103 helps control the cancer better than pembrolizumab alone.
Buffalo, New YorkAges 18 years+ - NCT07000084RecruitingPhase 3
Testing gemcitabine with BCG for returning bladder cancer
This trial tests whether adding a chemotherapy drug called gemcitabine to the usual BCG therapy can help prevent bladder cancer from coming back again. If you have had BCG before and your cancer returned, this study might offer a more effective treatment option.
Birmingham, AlabamaAges 18 years+ - NCT07357311Recruiting
Screening for Fear of Cancer Recurrence
This study aims to help people with breast or lung cancer who worry about their cancer coming back. You will answer questionnaires about your fears, so the care team can better support you.
ParisAges 18 years+ - NCT07012031RecruitingPhase 1/Phase 2
Sotorasib and trastuzumab deruxtecan for KRAS G12C lung cancer
This trial tests a combination of two drugs, sotorasib and trastuzumab deruxtecan, for people with advanced or metastatic non-small cell lung cancer that has a KRAS G12C mutation. It may be an option if you've already had treatment with a KRAS G12C inhibitor, immunotherapy, and chemotherapy.
Sacramento, CaliforniaAges 18 years+ - NCT04181060RecruitingPhase 3
Osimertinib alone or with bevacizumab for EGFR-mutant lung cancer
This Phase 3 trial tests whether starting osimertinib with or without bevacizumab helps people with advanced EGFR-mutant lung cancer live longer and control the cancer better. Your EGFR mutation test result and past treatments are key to whether you can join.
Anchorage, AlaskaAges 18 years+ - NCT07322341RecruitingPhase 2
Study of SX-682 with atezolizumab for advanced lung cancer
This trial tests a new drug combination (SX-682 plus atezolizumab) for people with advanced non-small cell lung cancer that has grown after standard treatments like immunotherapy and chemotherapy. It aims to see if the combination can help shrink or slow the cancer.
Seattle, WashingtonAges 18 years+ - NCT06104618RecruitingPhase 2
Enfortumab vedotin for advanced penile cancer
This trial tests a drug called enfortumab vedotin for people with advanced penile cancer (squamous cell carcinoma) that has spread or cannot be surgically removed. The goal is to see if the drug can shrink tumors or slow the cancer's growth.
Phoenix, ArizonaAges 18 years+ - NCT06897488RecruitingPhase 2
Omitting endocrine therapy and radiation in low-risk breast cancer
This trial tests whether older women with very low-risk, hormone-positive breast cancer can safely skip endocrine therapy (hormone-blocking pills) and radiation after lumpectomy. It aims to maintain quality of life while keeping cancer from coming back.
Houston, TexasAges 60 years+ - NCT04344496Recruiting
Collecting breast cancer tissue to predict recurrence risk
This study builds a “genome atlas” to better predict the chance that breast cancer will come back. It asks participants to share medical information and provide blood and tumor tissue samples, including samples kept in paraffin.

Camizestrant and ribociclib for advanced hormone-receptor-positive breast cancer
This trial tests a combination of two drugs (camizestrant and ribociclib) for advanced breast cancer that is hormone-receptor-positive and HER2-negative. The study aims to see if this combination helps patients whose cancer cannot be surgically removed or treated with radiation alone.
