Active clinical trials for "Measles"

Background: The safety of vaccination in patients with autoimmune diseases using immune suppressive therapy is often discussed. Previous studies in Juvenile Idiopathic Arthritis (JIA) patients showed no increase in disease activity after immunisation with dead vaccines. The safety of the live attenuated Measles, Mumps, Rubella (MMR) vaccination was assessed retrospectively in JIA patients and no increase in disease activity was found. However, this must be prospectively confirmed. In addition, it is unknown whether vaccination is effective, since the immune response to vaccination may be diminished due to immunosuppressive therapy for the underlying disease. Finally, the influence of MMR vaccination on the immune system of JIA patients has not been studied. Among others, regulatory T-cells (Tregs) should control the immune response and prevent destructive autoimmune responses after environmental triggers such as vaccination. Objective: The aim of the present study is to investigate the safety and efficacy of the MMR booster vaccination and its influence on immune regulatory mechanisms in children with Juvenile Idiopathic Arthritis. Method: JIA patients aged 4 to 8 years and treated by the pediatric rheumatology units from various University Medical Centers in the Netherlands, are asked to participate in a prospective study. In the Netherlands, measles-mumps-rubella (MMR) vaccination is included in the National Vaccination Program and is normally administered at age 9. Included patients will be randomised for early vaccination (age group 4 to 8yr at entry of the study) or at age 9 as is routinely done according to the National Vaccination Program. Prior to and after vaccination the investigators will assess disease activity and collect blood. Outcome: During a 12 month follow-up period the investigators will register disease activity and side-effects at different moments in time to determine safety of vaccination. The efficacy of the vaccine will be studied according to antibody levels and function against measles, mumps and rubella in the blood. Tregs will be isolated and their functionality will be determined using the blood cells collected during follow-up. This enables us to study the role influence of vaccination on regulatory mechanisms in our immune system.

Primary objective: To describe the safety profile of a refrigerator-stable formulation of VARIVAX® as a first single dose injection in 12 to 15 month-old infants in the 42-day follow-up period post-vaccination. Secondary objectives: NA

This is a phase 1/2, single-centre, double-blind, double-dummy, randomized, active-controlled, age de-escalation trial. Age de-escalation will be based on a review of the safety data from the preceding cohort (adults for toddlers and toddlers for infants) up to day 14 post study product administration by a data monitoring committee (DMC). All participants will receive either the MRV-MNP and a placebo (0.9% sodium chloride) SC injection (PLA-SC) or a placebo-MNP (PLA-MNP) and MRV by the SC route (MRV-SC). Only those study staff randomizing participants and preparing the study products for administration will be aware of the products administered. Those administering the study products, all other trial staff and the participants and parents will be blinded to treatment group. 45 adults (18 to 40-years-of-age) will be randomized in a 2:1 ratio. Thus, 30 adults will receive MRV-MNP and PLA-SC while 15 adults will receive MRV-SC and PLA-MNP. 120 toddlers (15 to 18 months-of-age) will be randomized in a 1:1 ratio. Thus, 60 toddlers will receive MRV-MNP and PLA-SC while the same number of toddlers will receive MRV-SC and PLA-MNP. 120 infants (9 to 10 months) will also be randomized in a 1:1 ratio. Thus, 60 infants will receive MRV-MNP and PLA-SC while the same number of infants will receive MRV-SC and PLA-MNP. Solicited local and systemic AE will be collected daily from all participants from the day of study product administration to day 13 post study product administration. Unsolicited AE and SAE will be collected from the day of study product administration to day 180 post study product administration. All participants will have laboratory investigations (hepatitis B, hepatitis C, hematology and biochemistry) conducted as part of screening. Adults will have safety laboratory investigations repeated on day seven and day 14 post study product administration. Toddlers and infants will have safety laboratory investigations repeated on day seven post study product administration. All participants will have measles- and rubella-specific SNA titers and measles- and rubella-specific IgG concentrations measured at baseline and day 42 and 180 post study product administration. Other Expanded Program on Immunization (EPI) vaccines due in toddler (oral poliovirus vaccine, diphtheria-tetanus-pertussis) and in infants (oral poliovirus vaccine, yellow fever vaccine and MenAfriVac® [due at 12 months]) will be given by the investigator team at the day 42 study visit (V4).

Primary objective: To compare if, when given concomitantly with VARIVAX® by the same route at 12-18 months of age using separate injection sites, a single dose of M-M-RTMII administered by IM route is as immunogenic as a single dose of M-M-RTMII administered by SC route in terms of response rates to measles, mumps and rubella at 42 days following the vaccination. AND/OR To compare if, when given concomitantly with M-M-RTMII by the same route at 12-18 months of age using separate injection sites, a single dose of VARIVAX® administered by IM route is as immunogenic as a single dose of VARIVAX® administered by SC route in terms of response rate to varicella at 42 days following the vaccination Secondary objectives: To summarise the antibody titres to measles, mumps, rubella and varicella at 42 days following the vaccination in children immunised with M-M-R™II and VARIVAX® administered concomitantly at two separate injection sites by the same route IM or SC, To evaluate the safety profiles of M-M-R™II and VARIVAX® administered concomitantly at two separate injection sites by the same route IM or SC.

It is a clinicaltrial Phase III , randomized, double -blind , 4-arm (390 each one): This study will include 1560 children and will use 3 batches of vaccine produced by Bio - Manguinhos with viral bulk of GSK combined measles , mumps and rubella applied in healthy children 12-15 months of age, and 01 batch of MMR to reference( GSK ), applied in healthy children aged 12-15 months old . The vaccine is administered as MMR 1st dose. Two hypotheses are tested : Consistency of production ( equivalence between batches )of 3 batches of vacines(TV1, TV2 , TV3 Bio- Manguinhos). Noninferiority vaccine Bio TV (Fiocruz, Rio de Janeiro), ie, the measles, mumps and rubella in Brazil is as immunogenic and safe as the measles, mumps and rubella reference, already used in routine NIP (production Bio-Manguinhos/FIOCRUZ with viral concentrate, bulk, GSK). The MMR vaccine (Bio-TV) will have the same composition (vaccine strains) and the same method of production of MMR (TV-GSK): Wistar RA27 / 3 rubella, Schwarz strain of measles vaccine, and strain RIT 4385 - derived from the Jeryl Lynn strain of mumps vaccine. As 2nd dose, children receive the vaccine tetraviral measles-mumps-rubella-varicella, aged 15-18 months, according to the guidance of the National Immunization Program. Noninferiority vaccine Bio TV (Fiocruz, Rio de Janeiro):the measles, mumps and rubella vaccine in Brazil is as immunogenic and safe as the measles, mumps and rubella reference, already used in routine NIP (production Bio-Manguinhos/FIOCRUZ with viral concentrate, bulk, GSK). Returns for blood sampling will be scheduled for 51 days, ranging from 42 to 60 days after dose of MMR vaccine dose and after tetraviral. We will colect the firt blood sample before the first vaccination too. It will describe the major adverse events observed after vaccination , comparing their frequency in groups of MMR vaccine with the Brazilian reference vaccine .

The objectives of the study are to assess the efficacy and safety of live, attenuated measles vaccine as consolidation therapy in patients with measles-positive, non-small cell lung cancer with locally-advanced (stage 3B with pleural effusion) or metastatic (stage 4) tumors in remission.

The present study will explore the immunogenicity of AVAXIM™ 80U-Pediatric in 12-13 months Turkish children and check if the administration of the MMR trivalent vaccine on the same day but at different site will interfere on immunogenicity for the four valences Hepatitis A, Measles, Mumps, and Rubella.

The purpose of this study is to demonstrate that an investigational refrigerated vaccine with measles, mumps, rubella, and varicella is well tolerated and has similar immune response when compared to a frozen vaccine with measles, mumps, rubella, and varicella.

Whether the lower immunogenicity of the mumps component obtained in clinical studies with the MMR in Brazil, due to the multidose presentation. Investigations were made on factors that could interfere with immunogenicity of mumps component, as the kits used for the immunoassay method, and potency of the vaccine, but no explanation was found. This study aimed to investigate the hypothesis that the lower immunogenicity of the mumps component of the MMR Bio-Manguinhos vaccine, is due to the multidose presentation. The Main objetctive is evaluate the immunogenicity of MMR after one dose in children 12 to 23 months of life, comparing the performances multidose vial (10 doses per vial of vaccine produced in Bio-Manguinhos/Fiocruz through technology transfer from GlaxoSmithKline Laboratory - GSK) and single dose vial (1 dose per vial of vaccine produced by GSK).

This study will compare Measles, Mumps, Rubella, and Varicella Vaccine (V221) and concomitant administration of Varivax and M-M-R II vaccines in healthy children.
