Belzutifan for Recurrent Clear Cell Gynecologic Cancer
This study tests a daily pill called belzutifan for people with a rare type of gynecologic cancer (clear cell carcinoma) that has come back or not gone away after standard treatments. The drug works by targeting a protein that helps tumors grow when oxygen levels are low.

Arsenous acid for hard-to-treat triple-negative breast cancer
This trial tests a medicine called arsenous acid for people with triple-negative breast cancer that has not responded to at least two prior treatments. If you join, you will get arsenous acid plus one of four chemotherapy drugs to see if the combination can shrink tumors.

Abemaciclib and radiation for metastatic breast cancer
This trial tests whether a targeted therapy (abemaciclib) combined with focused radiation (SBRT) to a bone tumor can help people with advanced breast cancer. It is for patients whose cancer is hormone receptor positive and HER2 negative, and who will continue abemaciclib after radiation.

Blood test study for head and neck cancer that has returned or spread
This trial is testing a new blood test (called a liquid biopsy) to better understand and predict the course of head and neck cancers that have come back or spread. If you join, researchers will use a special chip to look at your immune cells and tumor cells in your blood.
Zhubei, HsinChu CountyAges 20 years+ - NCT06678919Recruiting
A registry for metastatic colorectal cancer beyond second line
This study tracks people with metastatic colorectal cancer who have already tried at least two standard treatments. It aims to collect real-world data on how well newer treatments work in later lines of therapy.
LinzAges 18 years+ - NCT06679036RecruitingPhase 1/Phase 2
Combination therapy for advanced breast cancer
This trial tests new drug combinations for advanced or metastatic breast cancer. It aims to see if adding HRS-2189, HRS-6209, or HRS-1358 to standard treatments works better. Participants must have tried certain hormone therapies or chemotherapies before.
Harbin, HeilongjiangAges 18–75 - NCT06679101RecruitingPhase 3
Belantamab combination vs standard care for newly diagnosed multiple myeloma
This trial tests a new drug combination (belantamab mafodotin plus lenalidomide and dexamethasone) against the usual treatment for people newly diagnosed with multiple myeloma who cannot have a stem cell transplant. It aims to see if the new combination works better.
Mobile, AlabamaAges 18 years+ - NCT06679634RecruitingPhase 2
Topotecan eye patch for retinoblastoma
This trial tests a new way to deliver the chemotherapy drug topotecan directly to the eye (via a small patch placed on the eye surface) for children with retinoblastoma that either needs eye removal or has come back after standard treatment. It aims to see if this approach can help save the eye and vision.
New York, New YorkAges Up to 8 years - NCT06679816RecruitingPhase 4
Hydrocortisone for hormone replacement in large pituitary tumor surgery
This trial tests hydrocortisone as hormone replacement therapy after surgery for large pituitary tumors. It aims to help patients maintain healthy cortisol levels during recovery.
Beijing, Beijing MunicipalityAges 18–70 - NCT06679829RecruitingPhase 2
Melphalan with or without siltuximab for multiple myeloma stem cell transplant
This trial tests adding siltuximab to standard melphalan chemotherapy before a stem cell transplant. It is for people with multiple myeloma who are 60 or older and having a transplant within the first year of diagnosis.
Basking Ridge, New JerseyAges 60 years+ - NCT06679920Recruiting
New imaging probe to improve bladder cancer diagnosis
This trial tests a new optical probe that gives doctors a clearer view of bladder tumors during cystoscopy. It may help make diagnosis and treatment more accurate.
Amsterdam, North HollandAges 18 years+ - NCT06680089RecruitingPhase 2
Imaging test for kidney cancer using CD70-targeted drug
This trial uses a special imaging drug that targets CD70 (a protein on some kidney cancer cells) to see if it can better detect and track kidney tumors. It may help doctors understand how much cancer is present and guide treatment decisions.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06680323Recruiting
Melanoma risk factors in children and young adults
This study looks for genetic and environmental causes of melanoma in people up to age 30. It may help researchers understand why some young people get this type of skin cancer.
DüsseldorfAges Up to 30 years - NCT06680739RecruitingPhase 2
Study of immunotherapy for colorectal and endometrial cancer
This trial tests two immunotherapy drugs, durvalumab and tremelimumab, in people with colorectal or endometrial cancer that has spread or come back. The goal is to understand why some tumors persist or don't respond to treatment.
BarcelonaAges 18 years+ - NCT06680726Recruiting
Precision oncology research program for solid tumors
This research program studies solid tumors to find better treatments. It collects health data to help develop personalized cancer care.
ZurichAges 18 years+ - NCT06680752RecruitingPhase 1/Phase 2
A car-t cell therapy trial for AML or MDS
This trial tests a new CAR-T cell therapy, ARD103, for people with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) that has come back or is not responding to treatment. It aims to see if this therapy can help control the disease.

Temozolomide and stenoparib for relapsed small cell lung cancer
This trial tests two drugs—temozolomide and stenoparib—for people with small cell lung cancer that has returned after initial chemo. The goal is to see if this combination can shrink tumors or slow the cancer's growth.
Palo Alto, CaliforniaAges 18 years+ - NCT06681233Recruiting
Cone-beam CT for guiding radiation therapy in cancer patients
This study tests whether a special X-ray called cone-beam CT (CBCT) can help guide radiation therapy more precisely for different types of cancer. If you are already scheduled for radiation and use CBCT as part of your care, you may be able to join.
