This early-stage study tests COVID-19 treatments in people who have recently developed symptoms and who test positive for the virus. It aims to find safer, more effective options for preventing worsening disease, especially in higher-risk groups.
Cape TownAges 18 years+ - NCT04754854Recruiting
Testing less blood recirculation during veno-venous ECMO
This trial studies whether a change in how a veno-venous ECMO machine works can reduce “blood recirculation” (blood returning to the circuit too quickly) in people with severe lung failure. It may help improve oxygen levels in adults whose ARDS is not responding to standard treatment.
BerlinAges 18 years+ - NCT04756076Recruiting
Study heavy metal levels in pulmonary hypertension patients
This study looks at whether heavy metals in the body—and an imbalance of important minerals—are different in people with pulmonary arterial hypertension. It may help researchers understand possible causes and targets for future treatments.
Louisville, KentuckyAges 18 years+ - NCT04762199RecruitingPhase 1
MRX-2843 with osimertinib for EGFR-mutant lung cancer
This Phase 1 study tests whether combining MRX-2843 with osimertinib can help control advanced lung cancer that has specific EGFR gene changes. It is designed to find the safest dose and check early signs of tumor response.
Atlanta, GeorgiaAges 18 years+ - NCT04763447RecruitingPhase 4
Short omalizumab treatment for severe allergic asthma
This trial tests whether stopping omalizumab for a short time (or using it differently) can be safe for adults with severe allergic asthma who are doing well. It may help some people avoid long-term injections, but only if asthma remains well controlled.
Paris, Île-de-France RegionAges 18 years+ - NCT04767074Recruiting
Non-drug therapy to reduce long-term cough in lung scarring
This study tests a non-medication cough-control program for people who have lung scarring (interstitial lung disease) and a cough lasting more than 8 weeks. It may help you control coughing better without adding new medicines.
Hamilton, OntarioAges 18–85 - NCT04770207RecruitingPhase 2
Injecting a cancer drug mixture directly into tumors
This Phase 2 study tests a treatment where drug-loaded tiny beads are injected into a solid tumor, using more than one medicine. It may help people with advanced solid cancers by delivering the drugs right at the tumor site.
Guangzhou, GuangdongAges 18–99 - NCT04771520RecruitingPhase 2
Avapritinib for tumors with specific KIT or PDGFRA changes
This Phase 2 trial studies avapritinib, a targeted medicine, for people whose cancer has specific KIT or PDGFRA genetic changes. It may help shrink or slow growth of certain advanced cancers, including some brain tumors, when standard treatments have not worked or for specific glioblastoma cases.
Houston, TexasAges 18 years+ - NCT04772235RecruitingPhase 1
Test repotrectinib plus osimertinib for EGFR-mutated lung cancer
This Phase 1 trial tests how safe and effective repotrectinib plus osimertinib are for people with advanced or metastatic non-squamous lung cancer with specific EGFR mutations. It may help shrink tumors when surgery or radiation can’t cure the cancer, including in some cases after osimertinib or other EGFR pills.
Málaga, AndalusiaAges 18 years+ - NCT04772183Recruiting
Testing pulse oximeters against a blood-gas test in ICU
This trial compares how well different fingertip pulse oximeters measure oxygen levels, using an arterial blood test as the reference. It may help improve oxygen monitoring for ICU patients, especially when measurements can be hard or inaccurate.
Montreal, QuebecAges 18 years+ - NCT04772170Recruiting
Study wearable and symptom monitoring during respiratory virus challenges
This observational study looks for digital health patterns during studies where people are intentionally exposed to a respiratory virus. If you join a respiratory virus challenge at NIH, you may help researchers discover better ways to monitor and understand illness using wearable devices and shared health data.
Bethesda, MarylandAges 18–65 - NCT04773366RecruitingPhase 3
Newly diagnosed LCH children may receive cytarabine treatment
This Phase 3 trial tests a treatment plan that includes cytarabine for children newly diagnosed with LCH (a rare condition where abnormal immune-related cells form lesions). It may help control the disease while comparing outcomes with a cytarabine-based protocol.
ShanghaiAges 1 day–18 years - NCT04775134Recruiting
Checking leftover COVID virus after recovery
This study looks for whether small amounts of the COVID virus are still present in the lungs after infection. It may help doctors understand how long the virus can remain and inform future care, using tissue removed during a medically needed lung procedure.
LeuvenAges 18 years+ - NCT04777760Recruiting
Surfactant treatment for newborn breathing distress
This trial looks at giving a “surfactant” medicine (a substance that helps keep baby lungs open) to newborns who have serious breathing problems soon after birth. It may help babies with neonatal respiratory distress or acute breathing distress, especially if they’re treated in the early time window.

This Phase 2 study tests whether a combination of lenvatinib and a PD-1/PD-L1–blocking antibody (IBI318) can shrink advanced non-small cell lung cancer and is safe to use. It targets people whose cancer has specific genetic changes or specific prior treatment history, based on three different study groups.
