This phase 3 trial tests a new combination vaccine called BK1803 in healthy infants aged 2 to 7 months. The vaccine aims to protect against six diseases: whooping cough, diphtheria, tetanus, polio, hepatitis B, and Haemophilus influenzae type b. Researchers compare BK1803 to a st…

This trial tests a new recombinant polio vaccine (rPV) against the current standard IPOL vaccine in healthy adults aged 18 to 60. The goal is to see if the new vaccine is safe and triggers a strong immune response. It is a small, early-stage study to gather initial data.

This early-stage trial is testing a new vaccine designed to protect against several types of meningococcal bacteria, which can cause meningitis and bloodstream infections. Researchers will enroll 150 healthy people aged 2 to 59 to check the vaccine's safety and how well it trigge…

Researchers are testing a new way to deliver antibiotics to the brain in people with moderate to severe bacterial meningitis who are not improving on standard intravenous treatment. The approach combines standard IV antibiotics with a continuous infusion of three antibiotics (van…

This trial is testing whether a 10-week course of fluconazole works as well as the standard 24-week course for people with HIV who have a cryptococcal infection in their blood (antigenemia) but no symptoms. It also compares starting HIV medications right away versus waiting 14 da…

This study tests a drug called Sintilimab, which is normally used for cancer, to see if it can help people with HIV who have infections that won't go away with standard treatment. The drug works by 'waking up' exhausted immune cells. Fifty adults with HIV and a hard-to-treat infe…

This study tests a new method of giving antibiotics for moderate-to-severe bacterial meningitis. Instead of only giving antibiotics through a vein, doctors will also inject them into the skull bone to help more medicine reach the brain. The goal is to improve recovery in 86 adult…

This study tests a new two-drug combination (Alpibectir and Ethionamide) added to standard treatment for tuberculosis meningitis, a serious brain infection. About 64 adults newly diagnosed with the condition will receive the drugs to see how well they reach the brain and how safe…

This study tests a new antibiotic combination (BV100 plus other drugs) against hard-to-treat infections like pneumonia and bloodstream infections caused by carbapenem-resistant Acinetobacter baumannii. About 120 adults in the hospital will receive either the new combo or the best…

This study will compare two surgical methods for treating fluid collections in the brain that can occur after infant meningitis. One method uses a small camera (neuroendoscope) to remove debris and place a reservoir for drainage. The other is a standard burr hole drainage. The tr…

This study tests whether the antiviral drug aciclovir (or its pill form valacyclovir) works better than a placebo for treating meningitis caused by the herpes simplex virus type 2 (HSV-2). About 150 adults with confirmed HSV-2 meningitis will receive either the drug or a placebo,…

This study tests whether a short course of the steroid prednisolone can prevent paradoxical immune reconstitution inflammatory syndrome (IRIS) in people with AIDS who have low CD4 counts and are starting HIV treatment. About 131 participants will receive either prednisolone or no…

This early-stage study tests a lab-made antibody called TBE025 in 18 healthy adults aged 18 to 55. The goal is to see if it is safe and how the body processes it when given through a vein. Participants receive one dose and are closely monitored for side effects. This research hel…

This study will look at balance, core strength, leg strength, walking ability, and fatigue in 32 children aged 6-18 with demyelinating diseases (conditions affecting the protective coating of nerves). Each child will undergo a single session of non-invasive tests like balance exe…

This study follows 180 children who received a meningitis vaccine (ACYW135 conjugate) years ago to see if their immune protection lasts. Researchers will measure antibody levels in blood samples taken 3 and 5 years after vaccination. The goal is to understand how long immunity pe…

This study will recruit 100 sexual partners of people diagnosed with gonorrhea. Researchers will take an extra throat swab to analyze all the bacteria and their genes using a technique called metagenomics. The goal is to find hidden infections, antibiotic resistance, and see how …

This study aims to find what factors predict recovery in children with acute disseminated encephalomyelitis (ADEM), a rare brain condition. Researchers will follow 25 children aged 6 months to 18 years to see how many recover fully and how many have relapses. The study does not t…

This observational study will follow 50 patients with primary spondylodiscitis, a serious spinal infection, for one year. Researchers will track cure rates, pain levels, and daily function using standard treatments like antibiotics and braces. The goal is to understand how well c…

This study explores whether a blood test can identify the bacteria causing a brain abscess, potentially avoiding the need for brain surgery to get a sample. Researchers will compare the germs found in the blood with those found in the abscess during surgery in 15 adults. If succe…

This observational study will follow 100 children in Denmark who receive a stem cell transplant for blood cancer or other serious blood disorders. Researchers will test their thinking skills, physical abilities, and daily activity before the transplant and for one year after. The…

This study follows 600 Chinese children who received standard vaccines against polio, measles, mumps, rubella, and hepatitis A. Researchers will test their blood to see if protective antibodies remain 5 years after vaccination. The goal is to understand how long vaccine protectio…

This study will compare how well an AI program (Blings) measures speech clarity in 40 adults with speech disorders from stroke or other neurological conditions. Two speech therapists will also rate the same speech samples. The goal is to see if the AI can reliably replace or assi…

This study will follow 32 children diagnosed with their first episode of acute disseminated encephalomyelitis (ADEM), a rare brain inflammation that usually follows an infection. Researchers will check if early MRI scans, spinal fluid tests, and symptoms can predict which childre…

This study will follow 4,000 children in Cambodia to understand how common Japanese Encephalitis (JE) is and how often it spreads without symptoms. Researchers will compare healthy children with those hospitalized for fever and brain-related symptoms. The goal is to measure the t…

This study will follow 175 children and young adults who had a bone marrow transplant before age 18. Researchers will test their thinking, memory, and attention skills, and check for links to physical health issues like metabolism and fitness. The goal is to find early warning si…
