Study of gut microbes during immunotherapy for lung cancer
This trial studies how gut bacteria (the microbiome) and the body’s immune signs change over time while you receive PD-1–based immunotherapy for advanced, unresectable non–small cell lung cancer. The goal is to learn which immune and microbial patterns might relate to how well treatment works and how patients respond.

Proton therapy that avoids the hippocampus for slow brain tumors
This study tests a proton radiation plan designed to spare the hippocampus (a memory area) in children and teens with certain low-grade brain tumors. It may help deliver treatment to the tumor while reducing unwanted brain effects.

Testing inobrodib for blood cancers that came back
This is an early-stage study of inobrodib (CCS1477) for blood cancers like lymphoma, multiple myeloma, or acute myeloid leukemia that have returned or did not respond to standard treatment. It aims to see whether the drug is safe and can help control the cancer.
Atlanta, GeorgiaAges 18 years+ - NCT04075305Recruiting
Study measuring radiation treatment outcomes with an MR-Linac
This study follows what happens when radiation treatment is guided using an MR-Linac (a special machine that combines MRI imaging with radiation). It may help improve how radiation therapy is planned and assessed, especially for people who can safely have MRI scans.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT04081896Recruiting
Rehab program for adults with spine pain
This trial studies whether a prescribed physical therapy (rehab) program helps people with spine pain. It may help by improving pain and function when a clinician has already recommended rehabilitation.
San Diego, CaliforniaAges 18–89 - NCT04089631RecruitingPhase 3
Blood test guides extra treatment after stage II colon cancer surgery
This study uses a blood test called ctDNA to decide whether you need extra (adjuvant) chemotherapy after stage II colon or certain stage II rectal cancer surgery. It may help avoid unnecessary treatment or better target people who still have signs of cancer after surgery.
Dresden, SaxonyAges 18 years+ - NCT04095117Recruiting
Measure belly size to predict epidural depth in obesity
This study checks whether a measurement of belly size can help predict how deep an epidural needs to go in people with obesity. It may help make epidural placement safer and more accurate during planned leg surgeries.
CairoAges 18 years+ - NCT04095598Recruiting
CT scan with stress tests for unstable ankle ligaments
This study tests whether a special CT scan with gentle stress maneuvers can better find ankle ligament injury (syndesmotic instability) after a sprain. If you had a recent ankle sprain and exam suggests this specific injury, the scan may help guide the right treatment.
São Paulo, São PauloAges 18 years+ - NCT04099823Recruiting
MRI study of spinal fluid flow in memory or balance problems
This study uses MRI to look at how spinal fluid moves inside and around the brain. It aims to better understand conditions that can affect thinking, memory, balance, and coordination—such as normal pressure hydrocephalus—or compare with healthy people.
Rochester, MinnesotaAges 18 years+ - NCT04106479Recruiting
Baby heart ultrasound study in newborn congenital heart defects
This study records newborn heart measurements (using medical imaging) to compare babies with certain congenital heart defects to healthy-term babies. The goal is to see how well one test matches another, which may help doctors better understand heart conditions in newborns.
Montreal, QuebecAges birth–1 week - NCT04113070Recruiting
Study of childhood weight and early puberty development
This study follows children to see how body weight changes relate to when puberty starts and how it progresses. It may help doctors better understand healthy growth patterns during childhood.
Shanghai, Shanghai MunicipalityAges 6–12 - NCT04111588Recruiting
PET/MRI scan to assess brain tumors and metastases
This trial tests how well a special PET/MRI scan can help doctors evaluate gliomas and brain metastases. It may help improve diagnosis and treatment planning by comparing scan results with tissue samples or surgery findings.
BergenAges 18 years+ - NCT04122313Recruiting
Radiation after surgery for Dupuytren’s hand contracture
This trial looks at using radiation after contracture-release surgery for people with Dupuytren’s disease. It may help prevent the hand tightening from coming back and improve hand function.
Minneapolis, MinnesotaAges 18 years+ - NCT04130971Recruiting
Testing tumor tissue to understand and predict colorectal cancer response
This study looks at tissue samples from people with colorectal cancer to better understand tumor features and how they may respond to treatment. If you have colorectal cancer, the trial may help researchers match future treatments more effectively.
GothenburgAges 18 years+ - NCT04137835Recruiting
Noninvasive motion testing for arm and leg function
This study tests how well your upper and lower body moves using non-invasive methods (no procedures or surgery). It’s likely best for healthy adults who can follow instructions and want to help researchers measure movement and function.
Aurora, ColoradoAges 18–65 - NCT04142177Recruiting
Test which pain treatments work best for chronic low back pain
This study compares how well different pain treatments reduce low back pain and improve daily life. You may be asked to start or continue care through the VA and attend in-person sessions while completing pain and activity questionnaires.
Phoenix, ArizonaAges 18 years+ - NCT04140344Recruiting
Study texting messages after low back fusion surgery
This study tests whether regular text-message check-ins after lumbar (low back) fusion surgery are helpful for communication and follow-up. It enrolls people who will be getting their first low back fusion and who are comfortable texting and willing to stay in regular contact.

Non-invasive lung testing in asthma and cystic fibrosis
This trial studies how well a non-invasive lung test can show lung involvement in people with asthma (especially IgE-related asthma) and people with cystic fibrosis. You might benefit by getting extra lung assessments without invasive procedures.
