This trial tests a personalized treatment approach for recurrent or metastatic salivary gland cancer. It uses special tests on your tumor to find the best targeted therapy for your specific cancer type.
Beijing, Beijing MunicipalityAges 18–100 - NCT07117630RecruitingPhase 2
A new drug combo for advanced breast cancer after standard treatment
This trial tests a new drug combination for women with a certain type of advanced breast cancer (HR-positive, HER2-negative) that has worsened after standard treatments like CDK4/6 inhibitors and hormone therapy. It aims to see if the combination can help when other options have stopped working.
ShanghaiAges 18 years+ - NCT05406999RecruitingPhase 2
Intense hormone treatment before prostate surgery for high-risk cancer
This Phase 2 trial studies giving strong hormone-based treatment before prostate surgery to shrink and control high-risk, locally advanced prostate cancer. It may help improve surgical success and reduce cancer spread risk, but it requires careful health checks and prior-treatment limits.
Nanjing, JiangsuAges 18–80 - NCT05116579Recruiting
Using blood DNA tests to track PARP inhibitor response
This trial uses a blood test (circulating tumor DNA) to see whether PARP inhibitors are working for certain men with advanced prostate cancer. It may help predict which treatment responses are likely and monitor changes over time.
Guangzhou, GuangdongAges 18–75 - NCT07359066RecruitingPhase 1/Phase 2
SPR1020 for advanced solid tumors with DNA repair defects
This trial tests an experimental drug (SPR1020) for people with advanced solid tumors that have not responded to standard treatments, especially those with BRCA or related gene mutations. The drug is taken by mouth and the study aims to find the right dose and see if it helps shrink tumors.
Beijing, Beijing MunicipalityAges 18 years+ - NCT03990896RecruitingPhase 2
Talazoparib for metastatic breast cancer with BRCA body DNA changes
This Phase 2 trial tests talazoparib, a targeted cancer medicine, in people with metastatic breast cancer that has a harmful BRCA1 or BRCA2 mutation found in tumor DNA circulating in the blood. If you qualify, the goal is to see how well this treatment works when the mutation is detected this specific way.
San Francisco, CaliforniaAges 18 years+ - NCT04681469RecruitingPhase 2
Niraparib plus immunotherapy for HPV-negative head and neck cancer
This Phase 2 study tests a cancer “induction then maintenance” plan using a PARP inhibitor (niraparib) along with immunotherapy (TSR-042) in people with HPV-negative head and neck squamous cell cancer. If it works, it may improve control of the cancer after surgery by boosting the immune system and targeting cancer cells’ DNA repair.
BresciaAges 18 years+ - NCT05053854RecruitingPhase 1
Testing a PARP drug plus targeted radiation for bowel or pancreas tumors
This Phase 1 study tests how safe and effective it is to combine a PARP inhibitor (a targeted cancer medicine) with PRRT, a treatment that delivers radiation directly to certain tumor cells. It is for people with grade 2 neuroendocrine tumors from the pancreas or intestines, especially when scans suggest the tumor will take up the targeted radiation.
Melbourne, VictoriaAges 18 years+ - NCT05200260RecruitingPhase 2
Surgery plus maintenance medicines for advanced ovarian cancer
This trial checks whether having surgery to remove as much tumor as possible, followed by ongoing targeted treatment, helps people with advanced ovarian (and related) cancers live longer and/or control cancer better. It specifically uses tumor-testing results to match patients and then continues treatment after surgery.
FoshanAges 18 years+ - NCT05378204Recruiting
Testing DNA repair marker for PARP inhibitor resistance
This study looks at specific DNA “damage repair” proteins as a marker to understand why some BRCA-mutated breast cancers may resist PARP inhibitor treatment. Your biopsy (or existing biopsy) helps researchers study whether these lab markers relate to how well PARP inhibitors work.
