BordeauxAges 18 years+ - NCT04678193Recruiting
Study to track who may get hospitalized from COVID
This trial studies COVID risk to predict who is more likely to need hospital care and to better understand how COVID spreads. It may help future patients by improving risk assessment using test results and risk scores.
Phoenix, ArizonaAges 18 years+ - NCT04678648RecruitingPhase 1
Testing RSC-1255 in advanced cancers with RAS changes
This early study (Phase 1) tests a new drug, RSC-1255, in people with advanced or metastatic cancers that have RAS mutations. It’s mainly focused on whether the treatment can be given safely and at what dose, and to see if it may shrink tumors.
Los Angeles, CaliforniaAges 18 years+ - NCT04679584Recruiting
Study of long-term effects after COVID-19 infection
This study looks at how COVID-19 can affect health and quality of life over the long term. It may help researchers understand symptoms that can last and what changes people experience after recovery.
Würzburg, BavariaAges 18 years+ - NCT04681339Recruiting
Antibiotics in hospitalized children with community pneumonia
This study looks at how antibiotics are prescribed for children who are hospitalized with community-acquired pneumonia. It may help doctors choose more appropriate antibiotic use for kids in the hospital.

Using gut microbes to predict durvalumab side effects in lung cancer
This study looks at the microbiome (the tiny organisms in your gut) to try to predict who will get side effects from durvalumab after chemoradiation. If you join, your care team will use your microbiome results to help understand toxicity risk and improve future treatment planning.
Kansas City, KansasAges 18 years+ - NCT04684602RecruitingPhase 1/Phase 2
Study of stem cells for several short- and long-term illnesses
This early-stage study tests whether injections of mesenchymal stem cells can be safe and helpful for certain chronic (long-term) and acute (short-term) conditions. You might be considered if you can consent, are able to return for follow-up visits, and do not have key reasons that would make stem-cell treatment unsafe.
Culver City, CaliforniaAges 18 years+ - NCT04684459RecruitingEarly Phase 1
CAR-T therapy for tumors with HER2 and PD-L1 markers
This early-phase trial tests CAR-T cells designed to attack tumors that have high HER2 and PD-L1. It may help people with certain solid cancers that have not responded well to standard treatment.
Chengdu, SichuanAges 18–75 - NCT04686305RecruitingPhase 1
Test drug T-DXd plus immunotherapy, with or without chemotherapy for HER2+ lung cancer
This Phase 1 study tests the safety (and early effectiveness) of T-DXd combined with immunotherapy, sometimes also with chemotherapy, in people with advanced lung cancer that is HER2-positive. It may help if standard options have been limited or your tumor does not have certain genetic changes that already have targeted treatments.
Duarte, CaliforniaAges 18 years+ - NCT04691817RecruitingPhase 1/Phase 2
Testing tocilizumab plus atezolizumab after lung cancer treatment failure
This trial studies whether combining tocilizumab with atezolizumab can help people with advanced lung cancer that has already stopped responding to an immune checkpoint medicine. It may help when standard immune therapy (and other treatments) aren’t working anymore.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04700358Recruiting
Study of antibacterial antibodies in adults with cystic fibrosis
This study looks at how your body’s antibacterial antibodies work in people with cystic fibrosis. It may help researchers understand immune responses in cystic fibrosis and guide better future treatments.
CologneAges 18 years+ - NCT04701476RecruitingPhase 2
Pembrolizumab for advanced colorectal or lung cancer
This study tests pembrolizumab (an immune system medicine) with another treatment (TATE) in people with advanced colorectal or lung cancer that is not driven by certain gene changes. It may help shrink tumors after standard chemotherapy has stopped working.
Orange, CaliforniaAges 18 years+ - NCT04705766Recruiting
Study kidney injury after recent COVID infection
This study looks at how COVID can affect the kidneys soon after infection. You may be able to participate if you recently tested positive for COVID and have not had kidney replacement treatments.
San Francisco, CaliforniaAges 18 years+ - NCT04706390Recruiting
Study compares immune response after COVID infection vs vaccination
This study looks at how your immune system responds after natural COVID-19 infection compared with after COVID vaccination. It may help researchers understand how well different experiences train the body’s defenses.
BergenAges 20–100 - NCT04706754Recruiting
Study of lung cancer information across Canada
This observational study collects information from adults with lung cancer to better understand the disease over time. If you join, it helps researchers learn from real-world experiences rather than testing a new drug.
Brampton, OntarioAges 18 years+ - NCT04706988Recruiting
Asthma study linking lung bacteria to asthma types
This study looks at the tiny germs in your airways (airway microbiota) to better understand different asthma “types” and what might drive symptoms. It may help researchers find more personalized approaches to asthma care by learning how lung bacteria relate to your asthma features.
ShatinAges 18 years+ - NCT04707781Recruiting
Database study for people at risk of lung scarring
This trial is a study database that collects information from adults who have other illnesses that can increase the risk of developing interstitial lung disease (lung scarring). It may help researchers better understand who is at risk and how outcomes change over time.
GrazAges 18 years+ - NCT04707729Recruiting
Checking when to intubate patients on nasal high-flow oxygen
This study looks at a scoring system (ROX Index) to help decide the best timing to place a breathing tube (intubate) for adults who are struggling to get enough oxygen while using nasal high-flow (NHF). The goal is to see if using this timing approach can improve care for acute lung failure in the ICU.
Chicago, IllinoisAges 18–120 - NCT04710576RecruitingPhase 2
Axatilimab for chronic graft-versus-host disease
This trial tests a new drug called axatilimab to help patients whose chronic graft-versus-host disease (a condition where transplanted immune cells attack the body) isn't responding well to standard treatments. Researchers want to find the right dose and see if it can improve symptoms and quality of life.
Birmingham, AlabamaAges 2 years+ - NCT04712539RecruitingPhase 2
Baloxavir and oseltamivir for severe flu in immune-compromised people
This trial tests whether two flu medicines—baloxavir and oseltamivir—work better to treat influenza in people with weakened immune systems (like transplant or blood cancer patients). It may help reduce severe complications, especially when flu affects the lungs or is at high risk to do so.
Houston, TexasAges 12 years+ - NCT04711746Recruiting
Clonal blood changes after certain lung blood clots
This study looks at whether a specific kind of blood-cell change (“clonal hematopoiesis”) is linked to a lung blood clot (pulmonary embolism) that happened without a clear trigger. It compares people with unprovoked clots to people with provoked clots, after checking for inherited clotting risk factors.
AmiensAges 18–65 - NCT04712656Recruiting
CPAP treatment for sleep apnea and blood pressure changes
This study tests whether using CPAP (a breathing machine) for obstructive sleep apnea can improve blood pressure and heartbeat timing. You’ll have blood pressure checked at the start and again after 6 months, along with a sleep evaluation to confirm eligibility.
Columbus, OhioAges 30–75 - NCT04722835Recruiting
Study lung immune cells in people at risk for COPD
This study looks at different lung immune cell patterns and how they work in smokers who are not yet diagnosed with COPD or asthma. It may help researchers understand why some people are more likely to develop COPD, which could guide future prevention or early treatments.
San Francisco, CaliforniaAges 40–75 - NCT04728724RecruitingPhase 2
Check immune treatment before surgery for stage III lung cancer
This Phase 2 trial tests an “immunotherapy” medicine given before surgery for stage III non-small cell lung cancer. The goal is to shrink the cancer and make curative surgery more successful while monitoring safety and response.
