Study of safe temperature conditions for adults
This early study looks at which hot or cold environments are safest and most challenging for adults who don’t have symptoms of disease. It may help improve safety guidelines so older adults can exercise or be exposed to temperature changes more safely.
University Park, PennsylvaniaAges 18 years+ - NCT04343157RecruitingPhase 2
Image-guided radiation for brain tumors that protects thinking
This trial tests a special type of radiation therapy for brain tumors that aims to protect your memory and thinking skills. It may be an option if you have certain brain tumors or a small number of brain metastases.
San Diego, CaliforniaAges 18 years+ - NCT04347655Recruiting
Studies blood flow and heart pumping in adults with heart failure
This study looks at how well blood moves through the body and how strongly the left side of the heart pumps in adults. It compares people who have heart failure to people who do not, to better understand differences and possible causes.
Calgary, AlbertaAges 18 years+ - NCT04349852Recruiting
Memory and attention training for adults after brain injury
This trial tests a therapy that helps improve verbal working memory and attention in adults who had a traumatic brain injury (TBI). It may help by training thinking skills that are often affected after an injury, but it’s only for people who meet timing and mental health substance-use requirements.
New York, New YorkAges 18 years+ - NCT04262206RecruitingPhase 4
Testing how statins affect outcomes in adults 75 and older
This trial studies whether cholesterol-lowering medicine (a statin, specifically atorvastatin) improves health and benefits in people age 75 and older in everyday life. It may help doctors understand which older adults benefit most and how to use these medicines safely.
Birmingham, AlabamaAges 75 years+ - NCT04276870RecruitingPhase 2
CD19 gene-modified cells for high-risk B-cell leukemia
This Phase 2 trial studies CD19 “redirected” cells made from your own blood to treat certain high-risk or relapsed B-cell acute lymphoblastic leukemia (B-ALL). It may help by targeting cancer cells that carry a protein called CD19.
Philadelphia, PennsylvaniaAges birth–29 years - NCT04165772RecruitingPhase 2
Dostarlimab for locally advanced mismatch-repair deficient solid tumors
This Phase 2 trial studies dostarlimab (an immune therapy that targets PD-1) given before surgery or other initial treatment. It aims to shrink certain locally advanced cancers that have mismatch repair deficiency, potentially making treatment easier and improving outcomes.
Hartford, ConnecticutAges 18 years+ - NCT04197297RecruitingPhase 2
Brain scan tests for biomarkers in people with brain metastases
This trial studies brain scan findings to see if specific imaging markers can help understand or predict outcomes in people with brain metastases. It may help researchers improve how brain metastases are evaluated before radiation treatment.
Toronto, OntarioAges 18 years+ - NCT04202094Enrolling by invitation
Fertility options for young men after childhood cancer treatment
This study looks at fertility outcomes in young men who had cancer or blood disorders as children and then received high-risk treatment that can affect future fertility. It also compares people who did or did not store testicular tissue through a biopsy when they were younger.
BrusselsAges 18 years+ - NCT04240561Recruiting
Study of hearing aid results in people with Alzheimer’s dementia
This study looks at how much hearing aid outcomes vary in older adults who have Alzheimer’s dementia or mild memory problems. It may help researchers understand what hearing aids work best and for whom.
Chicago, IllinoisAges 50–90 - NCT04195633RecruitingPhase 2
Haploidentical donor stem cell transplant to treat blood cancers
This Phase 2 trial tests whether a specific stem cell transplant method (from a related “half-matched” donor) plus conditioning chemo and radiation can improve outcomes for several blood cancers. It may help people whose cancer is in remission but still considered high risk, or those who have had limited response after prior treatment.
Seattle, WashingtonAges 6 months+ - NCT04174066Recruiting
Study on kidney damage in children and adults with MGLS or FSGS
This trial collects medical data and blood/urine samples from patients with minimal change disease or focal segmental glomerulosclerosis (FSGS) to better understand how the immune system damages kidney cells.
NiceAges 1 year+ - NCT04165486RecruitingPhase 1
Test drug safety in adults with multiple system atrophy
This Phase 1 study checks how safe a drug called ION464 is, how the body handles it, and how much of the drug reaches the bloodstream in adults with multiple system atrophy (MSA). It may help researchers find a dosing approach for future treatments for MSA.
InnsbruckAges 40–70 - NCT04219254RecruitingPhase 1/Phase 2
Testing BI-1206 with pembrolizumab for advanced solid cancers
This early-phase trial studies BI-1206 together with pembrolizumab to treat advanced solid tumors. It may be an option if your cancer has progressed after prior anti–PD-1/PD-L1 treatment (or, in some groups, if standard treatments aren’t suitable).
Los Angeles, CaliforniaAges 18 years+ - NCT04094610RecruitingPhase 1/Phase 2
Repotrectinib for kids with certain cancer gene changes
This early-phase study tests repotrectinib, a targeted medicine, in children and young adults whose tumors have specific gene changes involving ROS1 or NTRK. It may help shrink advanced cancers that carry these gene alterations.

Study of a blood-filter treatment for FSGS not responding to meds
This study looks at how well a specialized blood-filter device (the LIPOSORBER® LA-15) works for people with primary FSGS—especially when standard steroid and other medicines don’t work or can’t be tolerated. It may help reduce disease activity, particularly in people with kidney function that is still moderate or in those after kidney transplant.
