Researchers are evaluating the consistency of immune responses to three different batches of an investigational chickenpox vaccine called VNS vaccine in healthy children aged 12 to 15 months who have not had chickenpox or received a chickenpox vaccine before. The study also compares the safety and immune response of the VNS vaccine to an approved chickenpox vaccine known as Varivax. This Phase 3a study is sponsored by GlaxoSmithKline and aims to better understand the immune protection provided by these vaccines. Participants are randomly assigned to receive one dose of either one of the three investigational VNS vaccine lots or one of two lots of the marketed Varivax vaccine. Along with the chickenpox vaccine, they also receive one dose each of measles, mumps, and rubella MMR vaccine, hepatitis A vaccine HAV, and a pneumococcal conjugate vaccine PCV which could be PCV 13, Vaxneuvance, or PCV 20 depending on availability and country recommendations. All vaccines are given on Day 1 of the study. During the study, researchers monitor the participants immune responses by measuring antibodies against varicella zoster virus VZV and other vaccine components at Day 43. They also track safety by recording any side effects or adverse events from Day 1 to Day 181. The study includes diary reports by parents and regular clinical evaluations to assess immune response and safety outcomes.

Researchers are evaluating the effects of elismetrep, an oral drug, compared with a placebo for the acute treatment of migraine in adults aged 18 to 75. This phase 3, double-blind, randomized study is conducted at multiple centers to assess the drugs safety, tolerability, and effectiveness in relieving migraine symptoms quickly. Participants receive either 10 mg or 20 mg of elismetrep or a placebo orally as part of the trial. The study uses a parallel design where participants are randomly assigned to one of these groups and neither the participants nor the researchers know which treatment is given until the study ends. During the trial, participants will be monitored for migraine pain relief and freedom from bothersome symptoms two hours after dosing, among other outcomes. Researchers will also assess pain relief at various time points, use of rescue medication, and safety by tracking any adverse events. Participants will complete questionnaires and use an eDiary app to record their experiences. The study is expected to last until February 2027.

Researchers are evaluating the safety and tolerability of a new multivalent pneumococcal vaccine called PG4 compared to the currently used 20-valent pneumococcal conjugate vaccine 20vPnC in healthy infants about 2 months old. The study aims to see if the new vaccine is as safe as the existing one and whether it can provide additional protection against infections caused by the Streptococcus pneumoniae germ, including pneumonia, meningitis, and ear infections. This is a phase 3, randomized, double-blinded trial conducted by Pfizer focused on prevention of pneumococcal disease. About 2400 infants will be randomly assigned to receive either the PG4 vaccine or the 20vPnC vaccine. Vaccinations are given by injection into the left thigh muscle at 2, 4, 6, and between 12 to 15 months of age. The study consists of two groups receiving these vaccines according to this schedule. The treatment period spans these vaccination times, with a total participation duration of about 16 to 19 months. During the study, infants will have six clinic visits and one phone call for monitoring. Parents or legal guardians will report any side effects or adverse events their infant experiences after vaccinations. Researchers will evaluate local and systemic reactions within 7 days of each dose, adverse events from the first dose through one month after the third and fourth doses, and serious adverse events up to six months after the last dose. Safety and tolerability data will be collected throughout the study period.

Researchers are studying influenza in children younger than 12 years to understand how the virus changes when treated with the drug baloxavir marboxil. This study has two parts Part A monitors the presence and development of specific changes in the virus before and after treatment in pediatric patients. Part B focuses on how influenza spreads within households from treated children under 12 to their family members, though no new participants will join Part B as per the latest study update. Participants receive a single oral dose of baloxavir marboxil on the first day, with the dose based on their body weight and age. Household contacts of the treated children are enrolled for observation but do not receive the drug. The study tracks viral changes and resistance at multiple points, including baseline and several days after treatment, and monitors influenza transmission within households. Throughout the study, children will undergo various tests such as local influenza and SARS-CoV-2 testing to confirm infection status. Researchers will measure how often virus mutations associated with resistance occur, changes in viral levels, and any side effects up to 29 days. For household contacts, influenza transmission and symptom development are checked on days 6 and 10. Participation involves scheduled visits and testing to gather this information, with the study expected to continue until mid-2027.

This trial investigates monitoring and treatment options for patients with low risk and standard risk metastatic germ cell tumors, which are cancers that start in the cells that produce sperm or eggs. The study aims to find out if active surveillance after surgical removal of low risk tumors can maintain high survival rates, and whether carboplatin or cisplatin chemotherapy works better for treating standard risk tumors in children, adolescents, and young adults. Patients with low risk tumors undergo observation after surgery and may transfer to a standard risk treatment arm if the tumor recurs. Those with standard risk tumors are randomly assigned to receive one of two chemotherapy regimens one containing carboplatin, bleomycin, and etoposide, or the other containing cisplatin, bleomycin, and etoposide. Treatments are given intravenously in cycles every 21 days for up to 3 or 4 cycles depending on the group. Throughout the study, patients have imaging scans, blood tests, tumor biopsies, and pulmonary function tests to monitor response and side effects. Participants are followed closely during treatment and afterward with regular check-ups including CT, MRI, and chest X-rays, as well as blood sample collections. Follow-up visits occur every 2 months for the first year, then every 3-6 months up to 2 years, every 6 months for years 3 to 5, and annually up to 10 years. Researchers measure overall survival, event-free survival, hearing loss, body composition, tumor markers, and patient-reported outcomes related to hearing and neuropathy. This long-term monitoring helps assess the effects and safety of chemotherapy and surveillance strategies.
