H1N1 Influenza Virus clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Analysis of the Results From Influenza Rapid Test A Positive and H1N1 Real Time RT-PCR

Start date: August 2010
Phase: N/A
Study type: Observational

The first outbreak of a new H1N1 influenza pandemic originated in the North America in April 2009. As of July 1, 2009, a total of 77,201 cases were accumulated in 103 countries around the world and the mortality rate of was about 0.43%. Alignment and analysis on gene sequences of the new H1N1 influenza virus found that it contains extremely homologous gene composition with that of the swine influenza viruses (swine flu) identified in Europe and North America in last century. Thus the virus strain was later renamed as a novel influenza H1N1. In general, the symptoms caused by the new influenza H1N1 infection was very similar to those resulted from seasonal influenza viral infection. Thus, it is difficult to distinguish the various influenza strains responsible for the infections only by clinical appearance. To compare the accuracy, specificity and sensitivity and speed in identifying the new influenza H1N1 in suspected cases, the investigators extracted RNA from influenza A-positive reactive specimens identified by a Influenza Rapid Test, for a Real-time PCR method to further detect the presence of swine H1 gene. In addition, the titer of H1N1 virus, the color development on the test stripe and clinical symptoms in patients were significantly associated. Finally, Real-time PCR products were subjected to sequence determination to explore potential new influenza pathogenicity, transmissibility and drug usage.
