St Leonards, New South WalesAges 18 years+ - NCT05526924RecruitingPhase 1
Phase 1 trial tests re-radiation plus immunotherapy and a cancer pill
This trial studies whether adding a checkpoint immunotherapy (tislelizumab) and a cancer pill (pamiparib) to radiation can better treat cancer that has come back in the head and neck. It’s for adults with previously treated, HPV-positive oropharynx tumors, usually without widespread spread.
Chicago, IllinoisAges 18 years+ - NCT05527470RecruitingPhase 3
Chemo then radiation for newly diagnosed advanced nasopharyngeal cancer
This Phase 3 trial tests giving chemotherapy first, then either radiation alone or chemotherapy together with radiation. It aims to improve treatment control for people with newly diagnosed, advanced nasopharyngeal cancer.
Guilin, GuangxiAges 18–65 - NCT05530655RecruitingEarly Phase 1
Finding the best lisinopril dose to prevent urine side effects
This early study tests which dose of lisinopril works best to help prevent urinary toxicity (urine/burning/urinary side effects) after radiation treatment for prostate cancer. If it’s effective for you, it could make radiation easier to tolerate.
Rochester, New YorkAges 18–70 - NCT05565326Recruiting
Testing MR-guided radiation checks for glioblastoma
This study tests how best to measure and track glioblastoma treatment while using MRI (a body scanner) to guide radiation. It may help improve how doctors assess the radiation response during therapy.
Zurich, Canton of ZurichAges 18 years+ - NCT05570422RecruitingPhase 1
Safety and early benefits of an injection plus radiation for cervical cancer
This Phase 1 study tests whether KRC-01, given by injection into the tumor, is safe and tolerable when combined with standard chemoradiation for locally advanced cervical cancer. It also looks for early signs that the treatment can shrink tumors.
ChandigarhAges 18 years+ - NCT05573074Recruiting
Light treatment trial for brain blood flow in depression
This study tests whether shining near-infrared light through the head can change brain blood flow and reduce depression symptoms. If you have major depression, you may be offered a non-drug, device-based approach to see how well it helps.
Boston, MassachusettsAges 18–65 - NCT05582265RecruitingPhase 3
Study immune drug plus chemo before surgery versus surgery first
This Phase 3 trial compares two treatment plans for stage III/IVA head and neck squamous cell cancer (HNSCC). One plan uses an immune drug with chemotherapy before surgery; the other goes straight to surgery first, to see which approach works better.
Guanzhou, GuangdongAges 18–80 - NCT05582499RecruitingPhase 2
Neoadjuvant treatment study for certain breast cancers
This Phase 2 study tests a “precision platform” approach—treatment before surgery—based on specific test results from your breast tumor. It may help determine whether the treatment plan works better for people with particular breast cancer subtypes and healthy organ function.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05595590RecruitingPhase 2
Radiation plus immunotherapy for recurrent head and neck cancer
This study tests whether adding an immunotherapy medicine called tislelizumab to radiation can better control recurrent (coming back) head and neck squamous cell cancer. It is aimed at people whose cancer can’t be fully removed by surgery or can’t be safely removed.
Chengdu, SichuanAges 18–75 - NCT05600400Recruiting
