Critical Path Initiative: A Conversation with Janet Woodcock, MD
September 1st 2005The "Critical Path" is the scientific process through which a potential pharmaceutical, or medical device is transformed from a discovery into a medical product. Along the critical path, scientific tests and tools are used to predict whether a product candidate will be safe and effective, to assess how prototypes interact with the human body, and to guide the sponsor in choosing an appropriate dose and regimen or device size and/or placement. To bring a product to market successfully and efficiently, product sponsors need scientifically sound approaches.
Phase III Failures: What Can Be Done?
September 1st 2005Much has been written about the staggering costs of drug development and how the low Phase III success rates across the pharma industry have contributed to these costs. While safety outcomes explain many failures during the early development phase and have likewise played a prominent role in some highly publicized product withdrawals, efficacy failures in Phase III have received little attention. What we now know, however, is that a significant number of Phase III failures are attributable neither to issues of safety nor product differentiation, but to an inability to confirm efficacy against placebo.
