Filter by:The primary objective was to assess the effect of Xepol compared to placebo on physical health and on muscle strength in subjects with post-polio syndrome.The secondary objective was to assess the effect of Xepol compared to placebo on functional balance, activity patterns, pain, fatigue, sleep, vitality, muscular strength, pulmonary capacity, walking ability, balance and safety.
Pre-licensure studies of GSK Biologicals' PEDIARIX vaccine have shown it to be generally safe and unlikely to result in vaccine-associated serious adverse events. This post-licensure study is designed to evaluate relatively uncommon/rare outcomes in a large population cohort.
To evaluate and standardize umbilical cord specimen collection and laboratory procedures to evaluate cellular and serological immune responses in neonates and young infants
As poliovirus eradication progresses rapidly, strategies to discontinue oral poliovirus vaccination need to be established. One strategy would be to use inactivated poliovirus vaccine (IPV) transitionally, and this has already occurred in the United States. It is not clear, however, if 3 doses of IPV provide sufficient immunogenicity when administered according to World Health Organization (WHO)/Expanded Programme on Immunization (EPI) schedule in a tropical, developing area where no wild-poliovirus circulates. Puerto Rico will be the study site for this randomized clinical trial. Healthy infants will be identified at birth in a hospital-system, enrolled within 4 weeks of birth, and randomized into one of two arms: United States of America (U.S.A.) schedule (8, 16, 24 weeks/2, 4, 6 months) or WHO schedule (6, 10, 14 weeks). Both groups will receive IPV at visits 1, 2 and 3. Infants will receive all age-appropriate EPI childhood vaccinations along with IPV, to decrease confusion and inconvenience to the parent. Serum will be collected twice, at visit 1 and visit 4 (30-45 days after IPV-3), to measure antibody titers. Sera will be measured for neutralizing antibodies at the Centers for Disease Control (CDC). Based on the lowest seroconversion rate estimate of 85%, and to have a probability of .80 that the estimate from this study is in error by no more than 10%, the investigators will need to enroll 220 infants in each arm. To compensate for attrition and retain statistical power, the investigators plan to enroll up to 250 infants in each arm. This study is expected to require at least 20 months to complete. Results will provide valuable and timely information applicable to global polio eradication efforts. Any participant found not to be protected after 3 doses of IPV will be given a booster at 9-12 months. Results will provide valuable and timely information applicable to global polio eradication efforts.
The purpose of this study is to evaluate the safety of administering a combination vaccine (DTaP-HepB-IPV; Pediarix™) to infants at birth, 2 and 6 months compared to the administration of a HepB vaccine at birth and the same combination vaccine at 2, 4, and 6 months of age. Additionally, researchers will assess the body's antibody response (proteins produced by the body's immune system that help fight infections) following each vaccine dose. The study will enroll 5 healthy newborns, ages 0-5 days. Participants will be involved in study related procedures for up to 288 days, including blood sample collection and 5 study visits.
The purpose of this study is to evaluate the safety, tolerability, and immune response of an investigational vaccine being evaluated to reduce the incidence of diphtheria, pertussis, tetanus, hepatitis B, poliomyelitis, and Haemophilus influenza type b.
Polio or poliomyelitis is the disease caused by the poliovirus. The virus attacks cells in the spinal cord and causes symptoms of fever, sore throat, headache, vomiting, and stiffness of the neck. Patients with polio can have long-term weakness of muscles as a result of the damaged cells in the spinal cord. Occasionally, patients that recover from the disease can experience a relapse of muscle weakness. This can occur as long as 25-35 years after first having polio. The condition is called "post-polio syndrome". Not all nerve cells in the spinal cord are damaged by the poliovirus. Some nerve cells remain healthy and take over the work of the damaged cells. Researchers believe that the "post-polio syndrome" may be caused by failure of these overworked nerve cells. However, what causes these overworked nerve cells to disintegrate is unknown. The purpose of this study is to apply specific scientific tests to answer important questions about the causes and development of the post-polio syndrome. Researchers will investigate possible genetic, immunologic, and physiologic causes of the "post-polio syndrome". The study itself will not provide therapy for patients with the condition, but may lead to the development of therapies in the future.
