Recruiting studies
- NCT05507411RecruitingPhase 2
Watch-and-wait after chemo-radiation plus immunotherapy for esophagus cancer
This Phase 2 study tests whether adding an immunotherapy drug (camrelizumab) to standard chemo-radiation can help some people with operable esophagus cancer avoid immediate surgery, using a “watch and wait” approach. If it works, it may reduce the need for early surgery for carefully selected patients.
Hanzhou, ZhejiangAges 18–75 - NCT05514275RecruitingPhase 2
Radiation plus endostatin and capecitabine for nasopharyngeal cancer
This Phase 2 trial tests whether adding endostatin and capecitabine to standard radiation can improve outcomes for people with non-keratinizing nasopharyngeal cancer that has not responded well to chemotherapy. It may help those with stable or worsening disease after treatment before moving to radiation.
Hangzhou, ZhejiangAges 18–65 - NCT05526417Recruiting
Prehab program before treatment for deep leg soft tissue cancer
This trial tests an individualized “prehab” program (exercises and preparation before treatment) to improve recovery and surgical outcomes for adults with deep soft tissue sarcoma in the leg. It’s meant to help your body be as ready as possible for radiotherapy and surgery.
Scottsdale, ArizonaAges 18 years+ - NCT05529251RecruitingPhase 2
Reduce treatment for limited-stage testicular seminoma
This study tests whether you can have less intense treatment (“de-escalation”) while still treating a small, limited-stage testicular seminoma that is growing. It may help reduce side effects if you qualify.
BesançonAges 18 years+ - 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 - NCT05534438RecruitingPhase 2
Tested targeted radiation plus usual drug treatment in metastatic breast cancer
This Phase 2 study tests whether adding a very focused type of radiation to standard drug treatment can better control metastatic breast cancer. It is for people whose cancer is only progressing in one spot, seen on a PET scan.
Basking Ridge, New JerseyAges 18 years+ - NCT05557552Recruiting
Chemo and immunotherapy plus chest radiation for stage III lung cancer
This trial studies a treatment plan that combines chemotherapy, immunotherapy, and radiation to the chest for people with unresectable stage III non-small-cell lung cancer (NSCLC). It may help by delivering anti-cancer drugs while also shrinking tumors with targeted radiation, especially for people who are not able to have the standard “chemo and radiation at the same time.”
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05576480RecruitingPhase 2
Immunotherapy plus chemotherapy before surgery for rectal cancer without mismatch repair
This Phase 2 study tests penpulimab (an immunotherapy medicine) given with CAPEOX chemotherapy before surgery for rectal cancer that is “MSS” (not the mismatch-repair type). It aims to shrink the tumor and improve outcomes by treating before the operation.
Shanghai, None SelectedAges 18–75 - NCT05580562RecruitingPhase 3
ONC201 for newly diagnosed H3 K27M brain tumor after radiation
This study tests whether ONC201 (also called ONC201) can improve outcomes for people with a newly diagnosed H3 K27M–mutant diffuse brain tumor after they finish radiation. It looks for safety and whether treatment can help control the tumor.
Phoenix, ArizonaAges Any age - 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 - NCT05613452RecruitingPhase 2
Carbon ion radiation for peripheral lung cancer you can’t operate on
This trial tests whether carbon ion radiation (high-energy targeted radiation) can control peripheral non-small cell lung cancer in people who are medically unable to have surgery. It may help shrink or stop tumor growth while limiting harm to nearby organs.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05628038RecruitingPhase 2
Radiation plus immunotherapy for recurrent rectal cancer
This Phase 2 trial tests whether giving targeted radiation and an immunotherapy drug together can control locally recurring rectal cancer in the pelvis. It may help shrink tumors and slow disease growth, especially after certain prior treatments.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05634889Recruiting
Personalized breast radiation for limited lymph-node spread
This trial studies a tailored form of radiation treatment for some people with early breast cancer whose sentinel lymph-node biopsy shows cancer in 1–2 nodes. It may help improve local control while guiding the best radiation approach for your specific situation.
HelsinkiAges 18 years+ - NCT05634681Recruiting
Daily radiotherapy plan test for cervical cancer
This study tests a “plan of the day” approach to radiotherapy for cervical cancer to help deliver treatment more accurately each day. It may help reduce unwanted radiation to nearby organs while keeping cancer treatment effective.
OsloAges 18 years+ - NCT05664464RecruitingPhase 1/Phase 2
Glutamate drugs for newly diagnosed brain tumor treatment
This Phase 1/2 study tests whether “glutamate inhibitor” medications can be safely added for newly diagnosed glioblastoma, and how they affect treatment outcomes. It’s designed for adults who will also receive the standard chemo‑radiation plan with temozolomide.
Zurich, Canton of ZurichAges 18 years+ - NCT05671458Recruiting
Imaging guidance during head and neck tumor surgery plus radiation
This trial tests whether advanced imaging used during surgery can better guide where surgeons remove head-and-neck tumors. It also studies how this approach works alongside planned postoperative radiation therapy, which may be needed for more advanced tumors.
HeidelbergAges 18 years+ - NCT05673304Recruiting
Boost treatment before surgery for luminal B breast cancer
This trial tests a “boost” treatment given before surgery along with standard chemotherapy for luminal B–type breast cancer. It may help improve outcomes by strengthening treatment before the tumor is removed.
BolognaAges 18 years+ - NCT05674396RecruitingPhase 2
Short-course radiation to ease symptoms from head and neck cancer
This Phase 2 trial tests a specific, shorter type of focused radiation to help relieve symptoms from head and neck squamous cell carcinoma. It compares two radiation timing/planning approaches to see which better improves comfort and quality of life.
Houston, TexasAges 18 years+ - NCT05686798RecruitingPhase 1
Gene therapy plus radiation for recurring brain tumor
This early-phase study tests a “suicide gene” therapy delivered by a virus along with radiation for adults whose high-grade brain tumor has come back or grown again. The goal is to see if the treatment is safe and can help control the tumor.
Detroit, MichiganAges 18 years+ - NCT05717790Recruiting
Nimotuzumab with chemo and radiation for advanced nose cancer
This trial tests whether adding nimotuzumab (an anti-EGFR antibody) to standard chemotherapy and radiation can improve outcomes for people with advanced nasopharyngeal carcinoma. It may help the cancer respond better and control it more effectively after treatment.
Baise City, GuangxiAges 18–70 - NCT05724004Recruiting
Alectinib then targeted radiation for ALK-positive lung cancer
