15 Clinical Trials for Various Conditions
This is a study of CDC-9 inactivated rotavirus vaccine (IRV) microneedle patch (MNP) for intradermal administration in healthy adults aged 18 to 45 years at two dose levels in a 3-dose series. The purpose is to determine if it is safe and if the recipient's immune system responds to the vaccine.
Rotavirus Infections
This is a study of CDC-9 inactivated rotavirus vaccine (IRV) for intramuscular administration (IM) in healthy adults aged 18 to 45 years at two dose levels in a 3-dose series. The purpose is to determine if it is safe and if the recipient's immune system responds to the vaccine.
Rotavirus Infections
This is a pilot study to assess the safety and immunogenicity of pentavalent rotavirus vaccine (RV5) when administered according to an alternate dosing schedule (2-5 weeks, 2 months and 4 months). In this interventional, open-label study, infants 2 through 5 weeks of age (14 to 41 days) will be enrolled and vaccinated with RV5 according to a 2-5 week, 2 and 4 month schedule and infants 2 months of age (56 to 83 days) will be vaccinated according to the standard recommended schedule (2, 4, and 6 months of age). Sera will be obtained from subjects one month following the final dose of vaccine and will be assayed for anti-rotavirus IgA and rotavirus neutralizing antibody responses against the G1, G2, G3, G4 and P\[8\] serotypes. Post dose 3 G1 serum-neutralizing antibody (SNA) geometric mean titers (GMTs) will be compared between children receiving pentavalent rotavirus vaccine (RV5) according to the alternate dosing schedule versus the standard recommended schedule. Likewise, post dose 3 G2, G3, G4 and P\[8\] SNA and serum rotavirus IgA GMTs will be compared between children receiving RV5 according to the alternate dosing schedule and the standard recommended schedule. The safety and tolerability of RV5 in children receiving vaccine according to the alternate dosing schedule will be described.
Diarrhea, Gastroenteritis
This study will evaluate 3 doses of a new vaccine for rotavirus infection in healthy adult volunteers to determine if it is safe and if the immune systems of healthy adults respond to this vaccine.
Rotavirus Infection
The goals of this study are to see what effects the introduction of RV5(RotaTeq) vaccine has had in the community both on the number of rotavirus-associated hospitalizations and on the strains of rotavirus circulating in the community. The investigators will use cases of rotavirus gastroenteritis identified on the wards at Hasbro Children's Hospital during the 2007-2009 rotavirus seasons for a case-control study to estimate rotavirus vaccine effectiveness in preventing rotavirus-associated hospitalizations. The investigators plan to assess rotavirus vaccine coverage in Rhode Island using the state vaccine registry and to examine whether and to what extent rotavirus vaccine was used outside the recommended age limits (off label) during the first 2 years of its implementation in Rhode Island. Finally using the state child health database, KIDSNET the investigators plan to investigate the reasons that children may not have received rotavirus vaccine in order to better target educational efforts for parents and health care providers.
Rotavirus Gastroenteritis
The purpose of this study is to complete the total safety database size for GlaxoSmithKline Biologicals' (GSK's) human rotavirus (HRV) vaccine across the Porcine circovirus (PCV)-free development plan. This study used a purposely selected lot for PCV-free liquid HRV vaccine that is in the upper range of the usual release potencies. The PCV-free liquid HRV vaccine lots used were stored frozen in order to keep the titer stable until administration during the study. As the liquid formulation of GSK's HRV vaccine is not licensed in the US, the lyophilized formulation of the vaccine was used as a control in all phase III studies as part of the PCV-free development plan.
Infections, Rotavirus
The purpose of this study is to assess if there is any immune interference between the Porcine circovirus free (PCV-free) liquid Human rotavirus (HRV) vaccine and routine infant vaccinations currently in use in the US, namely Pediarix®, Hiberix® and Prevenar 13® as compared to the currently licensed lyophilized formulation of the HRV vaccine when co-administered with the same routine vaccinations in healthy infants 6-12 weeks of age
Rotavirus Infection, Rotavirus Vaccines
The purpose of this study is to evaluate the clinical consistency of three production lots of the Porcine circovirus (PCV)-free liquid formulation of oral live attenuated human rotavirus (HRV) vaccine and to evaluate the PCV-free liquid formulation of HRV vaccine as compared to the currently licensed lyophilised formulation of the HRV vaccine in terms of immunogenicity, reactogenicity and safety when administered as a two-dose vaccination in healthy infants starting at age 6-12 weeks. No new subjects will be enrolled in the extension phase of the study.
Infections, Rotavirus, Rotavirus Vaccines
This is a prospective randomized clinical trial that aims to evaluate the potential effects of the first dose of rotavirus vaccines on gastrointestinal motility and anatomy and blood and stool cytokine responses. It will also assess the association between these outcomes and the pattern of the shedding of vaccine strain rotavirus in the stool. Infants will be randomized to one of four arms: monovalent rotavirus vaccine (Rotarix®, RV1) alone, RV1 with other recommended vaccines, pentavalent rotavirus vaccine (RotaTeq®, RV5) alone, or RV5 with other recommended vaccines. Data derived from the pilot study will be used to assess the feasibility of conducting a larger scale study.
Intussusception, Rotavirus Infections
Rotavirus, sometimes called the "stomach flu," is the most common cause of severe diarrhea in children. Vaccines can prevent many types of infections and work by causing the body to make proteins called antibodies that fight infection. For some vaccines, more than one vaccination is needed so that the body will make enough antibodies to fight infection. The vaccines (RotaTeq® or Rotarix® oral vaccines) given in this study are recommended for infants by the Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices (ACIP). These vaccines require either 2 or 3 vaccinations to be effective. Healthy infants between 6 weeks and 14 weeks, 6 days of age at Visit 1 will participate for about 10-12 months. Study procedures include reaction assessment and blood sample.
Rotavirus Infection
The purpose of this study is to assess the safety and immune response of the rotavirus vaccine in infants who have undergone abdominal surgery.
Intestinal Failure, Rotavirus Vaccines
This observational cohort study, conducted through two existing large administrative health databases in the US (outside the Vaccine Safety Datalink) is planned to confirm the safety profile regarding lack of any association of intussusception with Rotarix within 60 days of vaccination in a real life setting (routine use) in the US. This study will also include monitoring of Kawasaki disease, convulsions, hospitalizations due to acute lower respiratory tract infections and all-cause deaths within 60-days of vaccination. This study involves three cohorts, one exposed and two control cohorts: infants who receive Rotarix (Exposed cohort) and infants who receive IPV vaccination (Unexposed cohort A and B). This is a combined prospective and retrospective cohort study. Prospective component of the study identifies and compares study outcomes following Rotarix and IPV vaccination in the Exposed cohort and Unexposed cohort A, respectively. Retrospective component of the study identifies and compares study outcomes following IPV vaccination in the Unexposed cohort B.
Infections, Rotavirus
Rotavirus infection is a common pediatric illness and is the leading cause of severe acute gastroenteritis (vomiting and diarrhea) in infants and young children. Since February of 2006, an oral vaccine to prevent rotavirus has been approved by the Food and Drug Administration (FDA). The company that makes the oral vaccine is Merck and Company. Since the FDA approval, the American Academy of Pediatrics (AAP) and that Advisory Committee on Immunization Practices (ACIP) has recommended the use of this oral vaccine in infants. A previous rotavirus oral vaccine, Rotashield, was removed from the market for concerns that it was causing an increase in a gastrointestinal (GI) disease called intussusception. However, the new rotavirus vaccine was studied by the manufacturer and was not found to cause an increase in the cases of intussusception. Intussusception is a disease in which a portion of the GI tract folds back on itself leading to GI tract obstruction or back-up. The manufacturer of the vaccine noted on package insert information that the vaccine was not studied, originally, in infants with a history of GI disorders or in infants who have had surgery on their abdomen. Currently, there is no information available in the scientific literature about the use of the oral rotavirus vaccine in infants with GI diseases or those who have had GI surgeries. The objective of the study is the assessment of safety and tolerability of the oral RotaTeq® vaccine for all infants participating in the study. All infants will be followed for clinical adverse events with active safety surveillance for the first 42 days after each dose and also monthly afterward for a total of 12 months from the first vaccination date. The secondary objective of the study is to quantify the immunologic response will occur in all of the infants in the study. Assessment of percentage of the number of infants who have a good immune response (three-fold rise in IgA titer or greater) to the complete rotavirus vaccine series (three oral vaccines in total) by a blood test to check the rotavirus immunoglobulin A (IgA) level in infants with short bowel syndrome compared to normal infants will occur. Infants, meeting eligibility criteria and whose parents have signed informed consent will have their study information collected. These infants will be tested for the presence of pre-vaccine anti-rotavirus antibody, IgA levels, as mentioned above. After the blood is obtained, participants will receive their first oral rotavirus vaccine dose between the ages of 6 weeks to 12 weeks of life per package insert information. This oral rotavirus vaccine may be administered with other routine pediatric vaccines at the participant primary care provider's office. The date of the rotavirus vaccine and lot number would be recorded on vaccine administration date cards. Most participants will have their vaccines given through the Infectious Disease clinic staff at the Children's Hospital of Michigan. Subsequent doses of the oral rotavirus vaccine will be given at a minimal interval between vaccines of four weeks. The third, and final vaccine dose must be given by 32 weeks of life. Any adverse reactions to the vaccine will be reported on the National Vaccine Adverse Event Reporting System and MedWatch forms. Finally, two weeks after the participants have had all three oral rotavirus vaccine doses, the second and final blood draw will take place for measuring the post-vaccine level of anti-rotavirus antibody, IgA. Participants in the study will be monitored by telephone contacts on days 7, 14, and 42 after each dose and within 48 to 72 hours of each dose of the rotavirus vaccine regarding any serious adverse events. Each infant will also be assessed in the clinical setting each week after a vaccine dose has been given. As above, parents of participants will be asked to fill out the vaccine report card and record the child's temperature, and any episodes of vomiting, diarrhea, blood in the stools or fussiness for the first seven days. The parents will also be asked to record any other events from day 8 through 42 after each vaccine is administered such as fever, ear infection, runny nose, etc. Afterward, parents will also have monthly phone call safety follow-ups during the 12 month period following the first vaccination. A Data Safety and Monitoring Board will oversee the study and it's progress and will have the ability to vote to stop the study.
Short Bowel Syndrome
To determine the effectiveness of rotavirus vaccines, active surveillance will be conducted at two sites, Cincinnati Children's Hospital Medical Center (CCHMC) in Cincinnati, Ohio and the Medical University of South Carolina (MUSC) in Charleston, South Carolina. Children born on or after April 1, 2006 presenting to CCHMC as an inpatient or for a short-stay or Emergency Department (ED) visit with acute gastroenteritis (AGE) and/or fever will be approached for enrollment. Children will be eligible if they have vomiting and/or diarrhea less than or equal to 10 days duration. Data including demographic information, illness characteristics and socio-economic status will be collected from each patient. A sample of the patient's stool will be collected within 14 days of the onset of symptoms. Stool specimens will be tested for rotavirus antigen by Rotaclone at CCHMC. All rotavirus positive stool specimens will be typed for common G and P serotypes. Using the children identified with rotavirus as our cases and the children who were rotavirus negative as our controls, we will conduct a case control study to assess the effectiveness of rotavirus vaccines, in particular Rotarix.
