16 antimicrobial compounds in late-stage clinical development Eight compounds have activity against gram-positive organisms Eight compounds have activity against both gram-positive and gram-negativeorganisms From these 13 pharmaceutical leaders,just 3 new compounds are in advanced clinical development, thus reflecting the companies’ decreased investment in this therapeutic area

Lights and shadows of clinical trials of HIV vaccines • The first three Phase III clinical trials have been discontinued for safety reasons, having more infections among the vaccinated than the placebo group. • Recently the Phase III clinical trial performed in Thailand using a priming with recombinant canarypox vector (ALVAC-HIV) plus two booster injections of a recombinant glycoprotein 120 subunit vaccine (AIDSVAX B/E) showed a 30% reduced infections in the vaccinated group. Published on October 20, 2009 N Engl J Med 2009;361.

All laboratories analysis of all patients of the hospital are stored into the central database. Periodically a procedure extracts analysis for all patients present in the database server and stores them into a shared directory on the server machine. SecureODBC on Internet An Open Source ETL (Extraction Transformation and Load) tool is installed server-side. An automated process extracts analysis from the shared directory, applies several transformations in order to make analysis fit physicians’ needs and stores them into the analysis table. The chemical analysis mask, with de-normalized data (one exam = one column) ETL tool loads data into a relational database, built with normalized structure and exposed on Internet/intranet via secure ODBC connection. Analysis structure is de-normalized in real-time during physicians db exploration and is shown in user friendly forms. User authentication provides access control and strict db privileges management. …read/write… Hematological analysis Chemical analysis Microbiological analysis Physicians’ home Virolab offices
Results: GRT vs. DHby therapy line There is an increase in performance by increasing the therapy line: i.e. all models predict better when there is a long known therapy history On the other hand, subsequent therapy lines are likely to be more unsuccessful
