Active clinical trials for "Streptococcal Infections"

Two Phase III trials to demonstrate the efficacy and safety of oritavancin in the treatment of complicated skin and skin structure infections (cSSSI) have been completed. The pharmacokinetic profile of oritavancin in humans suggests that oritavancin has the potential to be used safely and effectively when given either as a single dose or as an infrequent dose for cSSSI. Data from animals support this theory. SIMPLIFI has been designed to evaluate the efficacy and safety of either a single dose of oritavancin or an infrequent dose of oritavancin (First dose on Day one with an option for a second dose on Day five) compared to the previously studied dosing regimen of 200mg oritavancin given once daily for 3 to 7 days.

Bacteria carry substances on their surface called antigens. When antigens come into contact with the right kinds of cells in the body an immune reaction is caused. This reaction is often the symptoms of sickness that a patient feels. In order for the body to fight off the attack of antigens, it creates substances called antibodies. Antibodies counter the action of antigens and make the bacteria harmless. However, the immune system must learn how to make the right antibodies for the right antigens. Sometimes the body creates antibodies that confuse normal tissues as foreign and attack them. This is called an autoimmune reaction and sometimes occurs when the body is exposed to certain bacteria. One bacteria known for causing autoimmune reactions is Group A beta-hemolytic Streptococcus (GABHS). This bacteria often causes throat infections commonly known as "strep throat". Some researchers believe that the autoimmune reaction associated with strep throat infections may cause neuropsychiatric disorders, like obsessive-compulsive disorder and/or tic disorder in children. As a result, each time a child with one of these disorders experiences an infection with GABHS his/her symptoms can reoccur or worsen. Researchers believe that by giving patients a certain antibiotic, they can prevent GABHS infection and thus prevent the return of symptoms. This study is designed to test the effectiveness of the antibiotic Amoxicillin for the treatment of Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS). Patients will receive Amoxicillin for six weeks and placebos "inactive sugar pills" for six weeks in order to see if the medication is truly working. Effectiveness of the treatment will be based on the presence or absence of symptoms. If at the end of the study Amoxicillin is proven to be effective treatment for PANDAS patients may be offered the opportunity to continue taking the medication for an additional six months.

Participants who meet the eligibility criteria and who consent to participation or whose parents/legal guardian consent to their participation, will be enrolled in the study for a period of up to 14 days. Enrolment visit (Day 1) assessments for all participants will include the collection of throat swabs, testing by staff at the site using the ellume·lab Group A Strep Test and testing for Group A Streptococcus by a central laboratory using bacterial culture and polymerase chain reaction (PCR). All participants will be followed up with a phone assessment of adverse events between Days 2-14.

This is an open label booster vaccine follow-up study. Participants who had received a primary course of GBS-NN/NN2 or placebo in Study MVX0002 will be invited to return to receive a booster dose (or first dose in the case of placebo or vaccine naïve participants) 1 to 5 years after the completion of the primary course of vaccination. All participants will receive a single dose of GBS-NN/NN2 containing 50μg of each fusion protein.

The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of GSK Biologicals' 10Pn-PD-DiT vaccine in children aged between 2 and 17 years of age having asplenia, splenic dysfunction or complement deficiencies. In addition, this study will include an age-matched control group of healthy children aged 24-59 months in order to descriptively compare the immunogenicity of 10Pn-PD-DiT vaccine in the at-risk population to that of the general, healthy population one month after each pneumococcal vaccination.

The purpose of this study is to assess the immunogenicity in terms of antibody response and the safety/reactogenicity in terms of solicited and unsolicited symptoms and serious adverse events following primary vaccination of Mexican infants with pneumococcal conjugate vaccine GSK 1024850A co-administered with a diphtheria, tetanus, acellular pertussis (DTPa)-combined vaccine (Infanrix hexa) and rotavirus vaccine (Rotarix) in children during the first 6 months of age.

This is a study in a large number of healthy children less than 3 years old to measure the efficacy of GlaxoSmithKline (GSK) Biologicals' 10-valent pneumococcal conjugate candidate vaccine (Synflorix vaccine, or GSK1024850A) to prevent cases of pneumonia (lung infection) likely caused by bacteria (Streptococcus pneumoniae and Haemophilus influenzae) or cases of otitis media (ear infection) in children under 3 years old.

The purpose of this trial is to assess if the rate of febrile reactions following the co-administration of a booster dose of pneumococcal conjugate vaccines with standard infant vaccines is lowered when paracetamol is given prophylactically and to assess the impact of pneumococcal conjugate vaccine on pneumococcal and H. influenzae nasopharyngeal carriage compared to control group receiving meningococcal conjugate vaccine (GSK134612). This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00370318).

The purpose of this observer-blind study is to evaluate the safety, reactogenicity and immunogenicity of pneumococcal vaccines in elderly. Subjects will be vaccinated twice with an interval of two months.

The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of a booster dose of GlaxoSmithKline (GSK) Biologicals´ pneumococcal conjugate vaccine co-administered with a booster dose of DTPa-IPV/Hib (Infanrix-IPV/Hib) in preterm born children at the age of 16-18 months. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number =NCT00390910 ). Subjects participating in this study should have received three doses of pneumococcal vaccine in the primary study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
