MRI study of brain metastasis relapse after focused radiation
This study looks at MRI scan patterns to estimate the risk of brain metastases coming back after stereotactic radiosurgery (such as Gamma Knife or CyberKnife). It mainly helps by finding imaging clues that can guide follow-up after treatment.
SeoulAges 18 years+ - NCT05870475RecruitingPhase 2
Interferon plus ruxolitinib for hydroxyurea-resistant polycythemia vera
This Phase 2 trial tests a combination of pegylated interferon and ruxolitinib in adults with polycythemia vera who can’t tolerate hydroxyurea or don’t respond well to it. If you qualify, it may help control blood counts and disease symptoms when standard treatment hasn’t worked.
TianjinAges 18 years+ - NCT05870995RecruitingPhase 2
Chemo plus targeted conditioning for hard-to-treat AML
This trial studies a specific chemotherapy plan (called sequential CLAG-Ven) with a gentler “conditioning” treatment before a transplant or donor-based therapy. It may help people with refractory or quickly relapsing acute myeloid leukemia (AML) who have a suitable family or matched donor and can meet certain organ function and infection rules.
Shanghai, Shanghai MunicipalityAges 16–65 - NCT05870423RecruitingPhase 1
Testing PARP inhibitors with peptide radiation for NET
This early-phase study tests whether adding a medicine called a PARP inhibitor to peptide receptor radionuclide therapy (PRRT) can better control advanced or metastatic neuroendocrine tumors (NET). It may help by targeting tumor DNA repair while PRRT delivers targeted radiation.
Rotterdam, South HollandAges 18 years+ - NCT05870969Recruiting
Digital monitoring to catch liver cancer risk early
This study tests a digital (computer/phone-based) system to help track people with higher risk of liver cancer so cancers can be found earlier. It may help by guiding regular check-ins and making early diagnosis more efficient.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05871021RecruitingPhase 2
Bevacizumab plus careful dosing for glioblastoma after surgery
This Phase 2 study tests a protective approach using bevacizumab (a medicine that blocks VEGF) while doctors carefully increase the dose in people with glioblastoma. It’s meant to help control tumor growth and possibly reduce certain risks that can happen with blood-vessel–targeting treatments.
AugsburgAges 18–70 - NCT05871099RecruitingPhase 3
Laparoscopic stomach surgery with added heated fluid chemotherapy
This trial compares standard laparoscopic surgery for stomach cancer versus the same surgery plus HIPEC, which is heated chemotherapy placed in the abdomen during the operation. It aims to see if adding the heated chemotherapy improves outcomes for people with higher-stage stomach cancer.
Qingdao, ShandongAges 18–80 - NCT05870800RecruitingPhase 2
Study Immunotherapy and Chemotherapy Before Colon Surgery
This trial tests immunotherapy plus chemotherapy given before surgery for colon cancer that hasn’t spread. It aims to shrink or control the tumor and improve outcomes in people whose tumor has certain immune/biologic features.
Houston, TexasAges 18–80 - NCT05871762Recruiting
Choosing best treatment plans for mid-to-low rectal cancer
This trial studies how to choose the best treatment strategy for people with rectal cancer located in the middle to lower part of the rectum. It may help doctors match the right treatment plan to tumor location and your overall situation.
Beijing, Beijing MunicipalityAges Any age - NCT05871164Recruiting
Long-term study of radiofrequency treatment for pancreatic tumors
This study follows adults over time who are treated for a pancreatic tumor using ultrasound-guided radiofrequency through a thin needle. It aims to understand what happens after treatment and how patients do, so future care can improve.
ToulonAges 18 years+ - NCT05871892Recruiting
PET/CT or PET/MRI scans for suspected or diagnosed liver cancer
This study looks at how well special imaging scans (PET/CT or PET/MRI) work in adults with suspected or diagnosed liver cancer. It may help doctors better see the cancer and plan next steps.
AarhusAges 18–100 - NCT05872295RecruitingPhase 1
Study drug for HER2-positive advanced cancers
This Phase 1 trial tests IKS014 to see how safe it is and how well it works in advanced solid tumors that have HER2. You may be eligible if your tumor is HER2-positive (including certain “low HER2” types) and your body’s blood counts and organ function are strong enough.
Newport Beach, CaliforniaAges 18 years+ - NCT05871996Recruiting
Survey study for people with cancer and palliative or oncology care
This trial is testing a questionnaire about language used in cancer care. You may be able to help by filling out a survey if you are 18+ and receiving palliative care or ongoing anti-cancer treatment.
Dublin, County DublinAges 18 years+ - NCT05873192RecruitingPhase 2
Talazoparib plus enzalutamide before prostate surgery
This trial studies whether taking talazoparib and enzalutamide before surgery can shrink or control prostate cancer. If treatment works, it may make the cancer easier to remove with a radical prostatectomy.
Houston, TexasAges 18 years+ - NCT05872880Recruiting
Oral cancer treatment with chemo, then surgery and radiation
This trial studies giving chemotherapy first, then removing the tumor with surgery and follow-up radiation for certain cases of oral squamous cell carcinoma. It may help shrink and control the cancer before and after surgery, depending on how well the tumor can be fully removed.
Changsha, HunanAges 18–65 - NCT05872724RecruitingPhase 2
Personalized add-on treatment after cervical cancer surgery
This study tests whether a tailored “extra” treatment after surgery—guided by a lab test called minimal residual disease (MRD)—can reduce the risk of cervical cancer coming back. It focuses on people with certain stages of cervical cancer who can follow the treatment plan and study follow-up.
Suzhou, JiangsuAges 18 years+ - NCT05873231Recruiting
Gut microbiome study for diarrhea after anti-cancer treatment
This trial looks at how changes in the gut (microbiome) relate to diarrhea that can happen after starting anti-cancer therapy. It may help doctors better predict and manage treatment-related diarrhea.
GrazAges 18 years+ - NCT05873322Recruiting
Study glucose changes during steroid and asparaginase treatment
This study looks at how blood sugar changes in children and teens receiving treatment for ALL (a leukemia) or lymphoma. It focuses specifically on effects that may be caused by steroids and a medicine called PEG-asparaginase.
Aarhus NAges 1–17 - NCT05874063RecruitingPhase 3
Preventing blood clots during first chemotherapy for germ cell tumors
This Phase 3 study tests whether giving enoxaparin (a blood thinner) can prevent dangerous blood clots in people with advanced germ cell tumors starting their first chemotherapy. It is especially focused on people who are at higher risk of clots.
AngersAges 18 years+ - NCT05875155Recruiting
Saving eggs by freezing ovarian tissue during cancer or surgery care
This trial looks at freezing ovarian tissue to help protect future fertility for people who may lose ovarian function from medical treatments or ovarian surgery. It may help you preserve the chance to have children later when egg or embryo freezing alone isn’t an option.
Pittsburgh, PennsylvaniaAges Up to 39 years - NCT05874401RecruitingPhase 4
Trilaciclib added to topotecan for advanced small cell lung cancer
This study tests whether adding trilaciclib (a medicine given with chemotherapy) can improve outcomes for people with extensive-stage small cell lung cancer who are being treated with topotecan. It compares trilaciclib versus a placebo (inactive pill) while you receive topotecan.
SevilleAges 18 years+ - NCT05874492Recruiting
Spa therapy for radiation-related skin fibrosis after cancer
This trial tests whether a spa therapy program can improve “fibrosis,” or stiffened/scarred tissue and related skin problems, after radiotherapy for breast cancer or upper head/neck cancers. It aims to see if treatment can improve quality of life for people who still have moderate-to-worse symptoms months after radiation.
BordeauxAges 18 years+ - NCT05874921Recruiting
Registry for adults with UTUC treated with Jelmyto
This registry collects information about adults with upper tract urothelial cancer (UTUC) who received Jelmyto after it was approved. It helps doctors understand outcomes and real-world experience with Jelmyto.
Santa Monica, CaliforniaAges 18 years+ - NCT05875870Recruiting
Bright light and exercise program for lung or esophageal cancer
This trial tests whether a structured bright-light exposure routine combined with a specific exercise program can help people with newly diagnosed lung or esophageal cancer. You may be eligible if you’re in early-to-middle cancer stages and able to safely participate in walking-based activities.
