AngersAges 18 years+ - NCT05139095RecruitingPhase 2
Camrelizumab plus apatinib for high-risk pregnancy tumor
This Phase 2 trial studies whether combining camrelizumab (an immune medicine) with apatinib (a medicine that blocks blood-vessel growth) can improve treatment for women with high-risk gestational trophoblastic neoplasia (GTN) that is very high-risk, or has returned or resisted chemotherapy. It may help shrink the tumor and reduce the chance it comes back by using two different approaches together.
BeijingAges 18–60 - NCT03326310RecruitingPhase 1
Selumetinib plus azacitidine for high-risk blood cancers
This Phase 1 trial tests whether selumetinib and azacitidine can help people with high-risk chronic blood cancers. You may qualify if your disease is higher risk and has either come back, not responded, or needs treatment because of low blood counts or other concerning features.
Chicago, IllinoisAges 18 years+ - NCT05037279RecruitingPhase 3
Testing BCG treatment for bladder cancer after full tumor removal
This trial studies a BCG-based bladder instillation in people with newly diagnosed, intermediate- or high-risk non-muscle invasive bladder cancer who have had their tumor fully removed. The goal is to see whether this treatment is safer and works better to lower the chance of the cancer coming back.
Vancouver, British ColumbiaAges 18 years+ - NCT05055063RecruitingPhase 1
Belantamab for high-risk smoldering myeloma safety and early benefit
This Phase 1 trial tests belantamab mafodotin, a cancer medicine, in people with high-risk smoldering multiple myeloma to see how safe it is and whether it may shrink or control the disease. Because it’s an early-stage study, you would be closely monitored and treated with one main study drug.
Houston, TexasAges 18 years+ - NCT04913064Recruiting
White button mushroom supplement for inflammation in high-risk breast cancer
This trial tests whether a white button mushroom powder supplement can lower inflammation in postmenopausal women who have a high risk of breast cancer. If it helps, it could improve early prevention strategies for people at higher risk.
Duarte, CaliforniaAges 21 years+ - NCT04947254RecruitingPhase 2
Add niraparib to hormone therapy after prostate radiation
This Phase 2 trial tests whether adding niraparib to standard hormone therapy (androgen ablation) after radiation works better for men with high-risk, localized or locally advanced prostate cancer. It may help control the cancer for longer, while also collecting extra tissue and blood to study why the treatment works or doesn’t.
Houston, TexasAges 18 years+ - NCT04972942RecruitingPhase 1
Immunotherapy for high-risk T-cell blood cancers after transplant
This Phase 1 study tests a targeted immune treatment given after strong pre-treatment (myeloablative chemo plus total-body radiation) before or along with an allogeneic stem cell transplant.
