Looking back at EGFR-targeted pills for lung cancer
This study looks back at how people with non-small cell lung cancer (NSCLC) were treated with EGFR-targeted medicines (gefitinib, erlotinib, and osimertinib). It may help doctors understand which patients benefit most and what side effects to expect.
Guangzhou, GuangdongAges 18–85 - NCT06518382Recruiting
Study of leftover tumor after chemo and trastuzumab
This study looks at leftover breast cancer cells (after chemo and targeted therapy) to find out why some cells resist treatment. It may help doctors better understand how to treat HER2-positive breast cancer in the future.
Milan, LombardyAges 18 years+ - NCT06791941Recruiting
Studying therapy resistance in recurrent head and neck cancer
This study looks at why some head and neck cancers come back after treatment. It will test tumor tissue from people having surgery to see if certain proteins (mutant p53 and YAP) are linked to treatment resistance. Your participation could help researchers understand how to better treat these cancers in the future.
Roma, RomeAges 18 years+ - NCT06784336RecruitingPhase 2
Testing starch and a drug after stem cell transplant
This trial tests if adding a special starch and a drug called deferasirox can improve recovery for people who have a stem cell transplant for blood disorders. The starch may help with gut health and the drug reduces iron, which might help prevent complications.
Ann Arbor, MichiganAges 18 years+ - NCT05435495Recruiting
Study why PSMA radioligand therapy stops working
This study looks at tissue samples from tumors to understand how and why PSMA radioligand therapy may become less effective. If you have PSMA-avid cancer lesions that can be biopsied, the trial may help researchers find ways to improve treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT06717243Recruiting
Study on gene markers in lung cancer for treatment resistance
This study looks at genetic markers in two types of lung cancer (small cell and large cell neuroendocrine) to understand why some tumors stop responding to a standard treatment that combines chemotherapy with immunotherapy. If you have one of these cancers and are about to start this treatment, you may be able to join.
New York, New YorkAges 18–85 - NCT06616597RecruitingPhase 2
Targeting gut bacteria to help prostate cancer treatment work again
This trial tests whether adding metronidazole, an antibiotic, can make abiraterone work better in men with metastatic prostate cancer whose PSA is rising despite treatment. It aims to target gut bacteria that may be fueling resistance to the therapy.
Baltimore, MarylandAges 18 years+ - NCT07673861Recruiting
Using ctDNA to find resistance and guide cancer treatment
This trial uses a simple blood test to look for changes in your cancer's DNA that might show why your current treatment stopped working. The results could help your doctor choose your next treatment more precisely.
LondonAges 18 years+ - NCT06406608Recruiting
Personalized drug test for drug-resistant lung cancer
This trial tests a new way to choose your next treatment by growing a mini version of your tumor (an organoid) in a lab and seeing which drugs kill it best. It is for people with drug-resistant non-small cell lung cancer who have already tried at least two standard treatments.
Zhengzhou, HenanAges 18–75 - NCT06834672RecruitingPhase 3
New drug vs chemo for platinum-resistant ovarian cancer
