Filter by:This study will determine whether participants who receive the vaccine V419 at 2, 3, 4, and 12 months of age have an acceptable immune response to the vaccine. The study will also determine whether the immune response to V419 is similar to that of participants who receive a licensed vaccine control.
This study will determine whether three manufacturing lots of V419 (PR5I) induce similar immune responses to all of the antigens contained in V419 when given concomitantly with Prevnar13™ and RotaTeq™.
This is a study to assess the safety, tolerability, and immunogenicity of V419 (PR5I) when administered as an infant series at 2, 4, and 6 months of age followed by a toddler dose of DAPTACEL™, Prevnar 13™ and PedvaxHIB™ at 15 months of age. The study will determine whether subjects who receive V419 have a similar immune response to the vaccine compared to subjects who receive licensed component vaccine controls.
To determine whether response guided treatment with pegylated interferon +/- ribavirin is effective for the treatment of recently acquired hepatitis C infection. Response guided treatment is when the length of treatment is determined by how quickly you respond to the treatment.
This study of Kaletra (Lopinavir (LPV)/Ritonavir (RTV)) tablets will be conducted to clarify the following with regard to treatment with this drug: 1. Incidence and conditions of occurrence of adverse reactions in the clinical setting 2. Factors that may affect the safety and effectiveness of Kaletra (QD)
A Double-Blind, Randomized, Placebo-Controlled, Multiple Dose Ranging Study Evaluating the Safety, Tolerability, Pharmacokinetics and Antiviral Activity of GS-6620 in Treatment Naïve Subjects with Chronic Hepatitis C Virus Infection.
The purpose of this study is to determine if a new treatment is effective for the treatment of recurrent symptomatic oral herpes virus infections.
The study will be conducted using nasopharyngeal swab specimens collected prospectively from individuals suspected of having the signs and symptoms of an acute respiratory tract infection caused by a respiratory virus. A series of standard viral culture tests validated for routine use in the clinical laboratory, and/or a series of PCR-based Laboratory Developed Tests (PCR-LDT) validated by a central reference laboratory will be used to verify the performance of the investigational artus Influenza A/B RT-PCR test and the QIAGEN ResPlex II Advanced Panel test. From each specimen five (5) aliquots will be prepared: (a) one aliquot will be tested in real-time using the assigned viral culture reference methods; (b) one aliquot will be used to extract nucleic acid in real-time for investigational testing; (c) one aliquot of the specimen will be stored at --70C for subsequent shipment to the reference laboratory for PCR-LDT testing, (d) one aliquot will be archived at -70C for subsequent follow-up by the reference laboratory (e.g., bi-directional sequencing of positive specimens), and (e) any remaining specimen will be stored for the Fresh vs. Frozen Study. The extracted nucleic acid generated from the second aliquot (i.e., "b" above) will be split and subjected to testing by both the artus Influenza A/B RT-PCR test and the ResPlex II Advanced Panel test.
The study was designed to gather information regarding the use of palivizumab for the prophylaxis for respiratory syncytial virus (RSV) infection in high-risk infants in selected countries within Latin America.
A Phase 1, Randomized, Placebo-Controlled, Observer-Blinded, Escalating Dose-Ranging Study to Assess the Safety, and immunogenicity of 6 different recombinant RSV-F formulations in healthy adults (18 to 49 years of age). Study Objectives: Primary: - To assess and compare the safety, reactogenicity, and tolerability of 6 RSV-F protein particle vaccine formulations. Secondary: - To assess and compare the immunogenicity (neutralizing antibody and total anti-F antibody) of the 6 RSV-F protein particle vaccine formulations - To confirm the "dose sparing" and "value added" effects of the aluminum phosphate adjuvant
