Poliomyelitis

This study tests a new oral polio vaccine (nOPV3) in healthy young children, infants, and newborns in Panama. The goal is to see if it is safe and triggers a strong immune response compared to the current vaccine. About 1,500 participants will receive either the new or existing v…

This study tests two types of inactivated polio vaccine (Sabin strain and wild strain) given in different orders to 480 infants aged 2 months. The goal is to see which sequence triggers the best immune response and causes the fewest side effects. Participants will receive three d…

This phase 4 study compares a single dose of an inactivated polio vaccine (sIPV) in people aged 7 to 50 years with the standard three-dose series given to infants. Researchers want to see if one shot can produce a similar immune response. The trial is recruiting 180 healthy parti…

This study tests a new oral polio vaccine (nOPV1) in over 2,200 healthy young children, infants, and newborns in Bangladesh. Researchers will compare it to the current Sabin vaccine to see if it is safe and triggers a strong immune response. The goal is to find a more stable vacc…

This study tests whether giving two new oral polio vaccines (types 1 and 2) together is safe and works as well as giving them separately in healthy 16-week-old infants. About 675 babies in Panama will receive either the combo or single vaccines. The goal is to see if the combo ap…

This early-stage trial tests a brain-computer interface called BrainGate for people with paralysis from conditions like ALS or spinal cord injury. A small sensor is placed in the brain to interpret movement-related signals, allowing users to control a tablet computer just by thin…

This study is testing whether immune checkpoint inhibitors, drugs that help the immune system fight infections, can improve outcomes for people with progressive multifocal leukoencephalopathy (PML), a rare brain virus. Researchers will follow 66 patients over a year, measuring di…

This study tests whether giving patients donor-derived immune cells (VSTs) on a regular schedule can prevent dangerous viral infections after a stem cell transplant. 180 participants will be randomly assigned to receive VSTs either on a fixed schedule or only when a virus is dete…

This study tests several already-approved drugs to see if they can slow down motor neuron disease (MND) and help people live longer. About 1150 adults with MND will be randomly assigned to receive one of the study drugs or a placebo. The trial uses a flexible design, allowing ine…

This study tests whether specially grown donor immune cells (viral-specific T-cells) can safely treat viral infections that often occur after a stem cell transplant. These infections can be serious and sometimes don't respond to standard antiviral drugs. The approach aims to boos…

This study tests a new approach for people with motor neuron disease (ALS) that combines personalized brain stimulation with mixed reality exercise games. The goal is to slow disease progression and improve quality of life. One hundred adults with mild to moderate ALS will be ran…

This study is testing a smartphone app that records and analyzes speech to help diagnose and monitor neurodegenerative conditions like dementia, Parkinson's disease, multiple sclerosis, and motor neuron disease. Researchers will compare speech patterns from 150 people with these …

This study tests a powered leg brace called the Nomad in 36 people who have trouble walking due to conditions like stroke, multiple sclerosis, or spinal cord injury. Participants will use the brace at home for three months to see if it improves their walking speed, balance, and q…

This study tests whether whole-body electrical muscle stimulation (WB-EMS) can help adults with neuromuscular diseases like ALS, SMA, and muscular dystrophy exercise safely. Because these conditions weaken the nerves that control muscles, traditional exercise is often too hard. W…

This study screens 360 adults with neurodegenerative disorders like ALS, frontotemporal dementia, and progressive supranuclear palsy. Researchers will use medical history, physical exams, memory tests, movement analysis, MRI scans, and other tests to find common features and diff…

This study aims to collect samples and medical information from people of all ages who have or have been exposed to viral infections, including COVID-19 and herpes. Researchers want to understand how viruses affect healthy individuals versus those with weakened immune systems. Pa…

This study explores whether a non-invasive brain-computer interface (BCI) can help people with motor disorders, such as spinal cord injury or stroke, control assistive devices using their thoughts. Researchers will record brain signals with EEG and use machine learning to interpr…

This study aims to find early markers of Parkinson's disease, multiple system atrophy, and Lewy body dementia by analyzing samples from the nose, blood, and urine. Researchers will compare results from 180 people with these conditions and healthy volunteers. The goal is to improv…

This study follows 3,000 childhood cancer survivors in Switzerland to learn about long-term health problems caused by cancer treatments. Participants undergo physical exams, lab tests, and questionnaires during regular follow-up visits. The goal is to better understand and manage…
