Going to HIVR4P 2018?
VISC Statistician, Bryan Mayer, will be presenting an abstract at the upcoming HIVR4P 2018 meeting this week in Madrid, Spain. His poster, "The CAVD DataSpace data sharing and discovery tool facilitates exploration of HIV immunological data from pre-clinical and clinical HIV vaccine studies", highlights key features and several use cases utilizing data from the DataSpace including: Stop by and check it out! HIV Research for Prevention 2018 (HIVR4P 2018) is the… Read more
Durability analysis for NYVAC challenge study timing
VISC statistician, Bryan Mayer, used data from 4 NHP studies testing NYVAC products (CAVD 259, CAVD 277, CAVD 281, and CAVD 434) to inform the design of an upcoming challenge study. Data on the duration of immune responses from the Binding Antibody Multiplex Assay (BAMA), Intracellular Cytokine Staining (ICS), and Neutralizing Antibody (nAb) TZM-bl assays were explored to help define a timeframe for challenge administration during which responses are still… Read more
Sample size calculation for CAVD 641
Here, we illustrate a sample size calculation using data from the CAVD DataSpace. In this study, our objective was to estimate sample size for a SOSIPv4.1 trimer vaccine study, CAVD 641, comparing the following adjuvants: Alum-3M052, administered via subcutaneous and intramuscular routes, versus GLA-LSQ administered via the intramuscular route. The outcome of interest was viral ID50 neutralization titer measured using the TZM-bl neutralization assay. There are… Read more
Results from CAVD 434/AUP 567
Using data available in the DataSpace, VISC statisticians, Bryan Mayer and Jimmy Fulp, generated a new report reproducing the CAVD 434/AUP 567 study results published in the May 2017 issue of the Journal of Virology. The report provides a brief tutorial showing how they used DataSpaceR to access and analyze the CAVD 434 data. As an alternative to the export feature in the Grid, we’ve created an R package that simplifies access to the DataSpace database. DataSpaceR is a… Read more
