Stem cell transplant then polatuzumab for certain lymphomas
This trial tests whether doing your own stem cell transplant, followed by polatuzumab, can improve outcomes in people with specific B-cell non-Hodgkin or Hodgkin lymphomas that did not fully respond or has come back. It aims to add a targeted medicine after transplant to help control the lymphoma.

This study looks at how a structured exercise program affects the heart and blood flow in people living with HIV. It may help your care team understand who benefits most from exercise and how to do it safely.
Rio de Janeiro, Rio de JaneiroAges 30–50 - NCT04513288Recruiting
Immunonutrition with L-citrulline for ICU sepsis patients
This trial tests whether adding L-citrulline to tube feeding (enteral nutrition) can improve outcomes for people in the ICU with sepsis or septic shock. It may help support the body’s immune response while you’re critically ill.
Rennes, Brittany RegionAges 18 years+ - NCT04513626RecruitingPhase 2
HIV trial testing doravirine plus raltegravir in adults
This Phase 2 trial studies whether switching to a combination of doravirine and raltegravir can safely maintain control of HIV in adults whose virus is already well suppressed. It may help people who are currently on stable HIV treatment and are not resistant to these specific medicines.
Paris, Île-de-France RegionAges 18 years+ - NCT04525716Recruiting
Study of how COVID-19 affected surgery patients
This study looks at how the COVID-19 pandemic changed outcomes and experiences for people who had surgery in Stockholm during the study period. It may help hospitals prepare better plans for patients during future outbreaks.
StockholmAges Any age - NCT04525833Recruiting
Visit Tzu Chi gastroenterology clinic study
This study looks at people who have visited a Tzu Chi Hospital gastroenterology clinic. It may help researchers understand liver and other whole-body health conditions in patients who receive care there.
New Taipei CityAges 18–99 - NCT04527315Recruiting
COVID-19 survivors health registry and follow-up scans
This study enrolls adults who had COVID-19 to track longer-term health effects and match them with people who did not have COVID-19. Depending on eligibility, you may be asked to complete questionnaires and possibly have MRI or X-ray scans.
New York, New YorkAges 18 years+ - NCT04534127Recruiting
DaRT radiation device for skin and mouth or superficial tumors
This trial tests a targeted radiation device (DaRT seeds) to treat certain cancers on the skin, in the mouth, or in superficial soft tissue. It may help when standard treatment (like surgery or regular radiation/chemo) hasn’t worked, isn’t safe, or isn’t wanted.
JerusalemAges 18 years+ - NCT04536103Recruiting
Accelerated MRI scans after ACL knee injury surgery
This trial tests a faster MRI scan method to measure healing in the knee after an ACL (anterior cruciate ligament) tear and reconstruction. It may help researchers compare scan quality while participants go through standard rehab.
Cleveland, OhioAges 18–50 - NCT04538053RecruitingPhase 4
Simpler antibiotics for uncomplicated bone and joint infections in children
This trial looks at whether a simpler antibiotic plan can work for children with uncomplicated bone or joint infections that start in the community. It may help reduce the need for complicated treatment while still keeping the infection under control.
Kingswood, New South WalesAges 1–18 - NCT04545762RecruitingPhase 1
Anti-CD19 CAR-T for certain relapsed lymphoma
This Phase 1 study tests an anti-CD19 CAR-T cell treatment in adults with specific types of relapsed or treatment-resistant non-Hodgkin lymphoma. It may help by finding and attacking lymphoma cells that carry the CD19 marker, but it’s early-stage and eligibility is strict.
San Francisco, CaliforniaAges 18 years+ - NCT04544592RecruitingPhase 1/Phase 2
CD19 CAR-T for children and young adults with B-cell blood cancers
This trial tests a one-time, lab-made immune cell treatment (CD19 CAR-T) for certain B-cell blood cancers in children and young adults. It may help people whose leukemia or lymphoma is not responding to standard treatment or has come back.
Aurora, ColoradoAges 1 month–30 years - NCT04545242RecruitingPhase 4
Dexamethasone for severe lung failure from infections on ventilators
This trial studies whether dexamethasone (a steroid medicine) improves outcomes in adults who have sudden, severe breathing failure caused by an infection while they are on a breathing machine. It may help reduce inflammation in the lungs during critical illness.
Terrassa, BarcelonaAges 18 years+ - NCT04551378Recruiting
Study of how COVID affected young people with cancer
This study looks at how the COVID-19 pandemic affected the experiences of teenagers and young adults with cancer, including people who finished treatment. It may help improve support for cancer patients and survivors during public health crises.
Houston, TexasAges 18–39 - NCT04556188Recruiting
Study to improve cardiac surgery services for rheumatic heart disease
This study looks at whether building a better, sustainable cardiac surgery service can reduce the burden of rheumatic heart disease. It focuses on patients who need cardiac surgery at a specific hospital during a training and research program.
Addis AbabaAges 14 years+ - NCT04558450Recruiting
Study how COVID-19 affects blood vessel stiffness and aging

NancyAges 18 years+ - NCT04573062Recruiting
Study how people recover from COVID over time
This study follows adults who recently recovered from COVID-19 to better understand what happens during recovery and afterward. It may help researchers identify who is at risk for longer-lasting symptoms (often called “PASC”) and what changes over time.
