The volume is divided into five sections that cover the most important elements of drug development. The first section focuses on approaches using targeted therapies to inhibit cell growth. The second section describes how clinicians are evaluating targeted therapies in specific organ systems. The third section illustrates how various classes of pharmacologic and immunologic agents are developed for individual molecular targets. The fourth section details new drugs that have novel mechanisms of action. The final section looks to the future of targeted therapeutics and includes chapters on appropriate patient selection, use of combination therapy, dealing with tumor cell resistance, and more.
