PSMA PET/CT scan to assess Ra-223 treatment in advanced prostate cancer
This trial studies whether a special whole-body scan (PSMA PET/CT) can help assess how well Ra-223 (a targeted treatment) may work in men with advanced prostate cancer that has spread to the bones. It may help doctors choose and plan Ra-223 treatment more effectively.
Taoyuan CityAges 40–85 - NCT04949282Recruiting
Lutetium-177 treatment for advanced somatostatin-positive tumors
This study looks at outcomes for adults with tumors that are advanced (can’t be fully removed or has spread) and are getting worse, where tests show somatostatin receptors. It aims to understand how treatment with lutetium-177 helps people in this situation.
Santiago de Compostela, A CoruñaAges 18–100 - NCT04949737Recruiting
Study stomach bacteria and stomach cancer in Martinique adults
This study looks at how common Helicobacter pylori (a common stomach germ) is in adults with stomach cancer in Martinique, and how it relates to stomach cancer. It mainly involves answering questionnaires and allowing study details to be collected to better understand risk and patterns.
Fort-de-FranceAges 18 years+ - NCT04949646Recruiting
Nerve monitoring during rectal cancer surgery
This trial studies whether checking pelvic nerve signals during rectal cancer surgery (total mesorectal excision) is helpful. It may help surgeons avoid nerve injury while removing the cancer.
LarissaAges 18–90 - NCT04950959Recruiting
Registry for adults having CT-guided minimally invasive procedures
This study is an observational registry, meaning it collects information rather than testing a new treatment. It may help researchers better understand outcomes and care for adults who have CT-guided, minimally invasive procedures.
Burlington, MassachusettsAges 18 years+ - NCT04951622RecruitingPhase 3
Testing nipocalimab for adults with generalized myasthenia gravis
This Phase 3 study tests nipocalimab, a medication given by infusion (and in some groups by injections under the skin), to improve symptoms in adults with generalized myasthenia gravis (MG). It may help reduce weakness in daily activities, especially if you meet specific symptom and safety criteria.
Paradise Valley, ArizonaAges 18 years+ - NCT04951804Recruiting
EUS pain block for pancreatic cancer, with or without bupivacaine
This trial tests whether a nerve-blocking procedure during an endoscopy can reduce pain from pancreatic cancer. Participants will get the procedure either with or without bupivacaine, a local numbing medicine.
Montreal, QuebecAges 18 years+ - NCT04952272RecruitingPhase 1
Shots into the tumor to boost the immune system
This Phase 1 study tests an injection given directly into an advanced solid tumor to help the immune system better recognize and attack cancer. It may help people with advanced solid tumors, but the goal at this early stage is mainly to check safety and how the treatment works.
Guangzhou, GuangdongAges 18–80 - NCT04951635RecruitingPhase 3
Almonertinib after chemoradiation for stage III lung cancer
This Phase 3 trial tests whether almonertinib given after standard chemoradiation can help people with stage III, non-surgical lung cancer live longer and/or control the cancer. It is for tumors with specific EGFR mutations linked to sensitivity to EGFR-targeted medicines.
Ji'nan, ShandongAges 18 years+ - NCT04951947RecruitingPhase 2
Study drug plus lenvatinib for advanced small-cell lung cancer
This Phase 2 trial tests JS-201 combined with lenvatinib in people with extensive-stage small-cell lung cancer whose first-line treatment didn’t work. It may help by trying a new combination approach after prior therapy failure.
Changsha, HunanAges 18–75 - NCT04953897RecruitingPhase 1
Oral decitabine for cancer patients with kidney problems
This Phase 1 trial studies how an oral combination cancer medicine behaves in the body (dose handling and safety) in people with kidney impairment. It may help doctors learn the safest way to use this treatment when kidney function is reduced.
Houston, TexasAges 18 years+ - NCT04952480RecruitingPhase 2
Adaptive chest radiation for newly diagnosed small cell lung cancer
