Warsaw, MazovianAges 1–18 - NCT04943562Recruiting
Testing sleep sensors to score your sleep stages
This study checks whether wearable sensors (like a sleep band and a wearable EEG) and a phone can accurately identify your sleep stages. It includes healthy people and people with sleep problems to see how well the devices work and whether results match a standard sleep lab test.
São Caetano do Sul, São PauloAges 20–80 - NCT04943224RecruitingPhase 2
Trametinib dosing plan for BRAF-negative juvenile cancer
This Phase 2 trial tests whether trametinib can work in children or teens with a tumor that does not have BRAF mutations. It also studies the best timing and dose, especially after prior treatments have not worked or the disease came back.
Warsaw, MazovianAges 1–18 - NCT04944563Recruiting
Segmentectomy vs lobectomy for small middle-lung lung cancer
This trial compares two types of lung surgery for certain small lung cancers in the middle part of the lung: removing a segment (segmentectomy) versus removing a whole lobe (lobectomy). It aims to see which surgery works better while balancing cancer control and lung function.
Nanjing, JiangsuAges 18–75 - NCT04944030Recruiting
Study collects health data for metastatic lung cancer patients
This study collects medical information and test results from people with lung cancer that has spread (or cannot be cured with local treatment). It does not test a new drug; it helps researchers better understand patients’ health and care needs over time.
AngersAges 18 years+ - NCT04956445Recruiting
Donate blood and mucus samples to study virus treatments
This study collects samples from people who currently have, recently had, or may have been exposed to common respiratory viruses. The goal is to use these samples to develop and test future countermeasures (like treatments) against COVID-19 and other viruses.
New Orleans, LouisianaAges 6 months–120 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 - NCT04952480RecruitingPhase 2
Adaptive chest radiation for newly diagnosed small cell lung cancer
This study tests a customized (“adaptive”) way to give radiation to the chest for newly diagnosed small cell lung cancer. It aims to improve how well treatment targets the tumor while safely adjusting to tumor changes during therapy.
Edmonton, AlbertaAges 18 years+ - NCT04959734Recruiting
Study of COVID-19 effects on emergency visits for infant lung infections
This study looks at how the COVID-19 era changed emergency department visits for young children with breathing problems, such as bronchiolitis or first-time viral wheeze. It may help doctors understand trends in these illnesses and plan better care during outbreaks.
LeicesterAges birth–2 years - NCT04959175RecruitingPhase 1/Phase 2
Lower post-transplant drug doses for older or unfit patients
This trial tests whether giving a lower dose of cyclophosphamide after a bone marrow transplant can be safer for older or medically “unfit” patients, while still helping control blood cancers. It is designed for people who can’t tolerate the usual strongest transplant preparation.
Bethesda, MarylandAges 12–85 - NCT04965298RecruitingPhase 3
Lansoprazole add-on treatment for idiopathic pulmonary fibrosis
This Phase 3 study tests whether adding lansoprazole (a stomach acid medicine) can improve outcomes for people with idiopathic pulmonary fibrosis (IPF). You may already be on IPF “anti-fibrotic” medication, and the study checks if the added lansoprazole helps, compared with placebo.
Norwich, NorfolkAges 40 years+ - NCT04966663RecruitingPhase 2
Using blood DNA tests to guide lung cancer treatment
This study uses a blood test called ctDNA to look for leftover lung cancer after surgery. Based on that result, the trial will help decide which treatment approach is best for you and may catch cancer returning earlier.
Toronto, OntarioAges 18 years+ - NCT04966793Recruiting
