Antwerp, AntwerpenAges 70 years+ - NCT06043323RecruitingPhase 2
CAR T cells plus radiation for follicular lymphoma
This trial tests a combination of a CAR T-cell therapy (Axicabtagene Ciloleucel) with radiation therapy for people with follicular lymphoma that has come back or not responded to multiple treatments. The goal is to see if adding radiation can make the CAR T cells work better.
Houston, TexasAges 18 years+ - NCT06055517Recruiting
Re-irradiation with low-dose pulses for recurrent glioma
This trial tests a new way to deliver radiation therapy for people whose brain tumor (glioma) has come back after earlier treatment. Instead of standard radiation, it uses very low doses given in pulses, which may be safer for patients who have already had radiation to the head.
Aviano, PordenoneAges 18 years+ - NCT06043193Recruiting
Quality of life study for patients with neuroendocrine tumors getting internal radiation therapy
This study looks at how internal radiation therapy (RIV) affects quality of life in people with neuroendocrine tumors. It aims to understand how well patients tolerate this treatment and how it impacts daily life.
Saint-Priest-en-Jarez, Saint-EtienneAges 18 years+ - NCT06048926Enrolling by invitation
Carrelizumab with chemoradiation for advanced esophageal cancer
This trial tests combining the immunotherapy drug carrelizumab with standard chemotherapy and radiation for people with advanced esophageal cancer that cannot be surgically removed. It aims to see if this combination can help shrink or control the tumor.
NanjingAges 18–75 - NCT06048484RecruitingPhase 2
Combination therapy for localized pancreatic cancer
This trial tests a combination of drugs for people with localized pancreatic cancer who have already completed 8 cycles of modified FOLFIRINOX chemotherapy before surgery. The goal is to see if adding these drugs after chemo and radiation helps improve outcomes.
Lake Success, New YorkAges 18 years+ - NCT06016387RecruitingPhase 2
Drug combo with radiation for HER2+ breast cancer spread to spinal lining
This trial tests a combination of three targeted drugs (tucatinib, trastuzumab, and capecitabine) along with radiation to the brain or spine for people whose HER2-positive breast cancer has spread to the lining of the brain or spinal cord. The goal is to see if this treatment is safe and effective.
Ottawa, OntarioAges 18 years+ - NCT06030440RecruitingPhase 2/Phase 3
Lowering radiation after head and neck cancer surgery
