Talk Will Cover the Use of Pharsight Software for In-Vitro / In-Vivo Correlation Modeling in Drug Development MOUNTAIN VIEW, Calif., June 23 /PRNewswire-FirstCall/ -- Pharsight(R) Corporation (NASDAQ:PHST), a leading provider of software, strategic consulting, and regulatory services for optimizing clinical drug development, today announced that Jason Chittenden, MS, Director of Training and Pre-Sales, will speak to members of the pharmaceutical and biotechnology industries attending the Dissolution Testing, Bioequivalence & Bioavailability Strategies Conference, to be held in London, United Kingdom, by Visiongain, at The Grosvenor -- Victoria Hotel, June 26th and 27th, 2008. Mr. Chittenden will give a lecture on the use of Pharsight's software for in-vitro/in-vivo correlation (IVIVC) and its benefits in formulation design, bioequivalence, and development of dissolution specifications. Understanding and controlling the relationship between in-vitro release and in-vivo response in a compound plays a critical role in the development of modified-release formulations, generics, fixed-dose combination products, and drug delivery systems. The earlier in the drug development process IVIVC is implemented, the easier and more cost effective it is to implement all future changes in formulations. "Doing dissolution analyses with IVIVC is a fast and inexpensive method for obtaining optimal formulations as opposed to slow, expensive bioavailability or bioequivalence (BA/BE) studies that provide hit or miss results," said Shawn O'Connor, president, CEO, and chairman of Pharsight. "Pharsight's IVIVC Toolkit(TM) for WinNonlin(R) guides researchers to perform the right BA/BE studies and eliminate many that are unnecessary. With an average NDA having 3-6 BA/BE studies, avoiding just one unnecessary BA/BE study using the IVIVC Toolkit can easily yield a financial return of 12 to 1." About IVIVC Toolkit(TM) for WinNonlin(R) The IVIVC Toolkit for WinNonlin expands the capabilities of WinNonlin, enabling the use of WinNonlin for in-vitro/in-vivo correlations (IVIVC). The Toolkit brings enhanced deconvolution methods, numerical convolution, plotting capability, and the "IVIVC Wizard" to pharmacokineticists and formulators. IVIVC Toolkit speeds development of new formulations, helps reduce bioequivalence test failures, enables the setting of optimal dissolution specs for quality assurance, allows for visualization of the in-vitro/ in-vivo relationship using its plotting features, and allows for easy application of correlations to predict PK from new in-vitro data.
