Abstract

Despite the enormous progress made in the advancement of health technologies over the last century, infectious diseases continue to cause significant morbidity and mortality in developing countries. Neglected diseases are a subset of infectious diseases that lack treatments that are effective, simple to use, or affordable. Neglected diseases primarily affect populations in poor countries that do not constitute a lucrative market sector, thus failing to provide incentives for the pharmaceutical industry to conduct R&D for these diseases. Of the treatments that do exist for neglected diseases, most are completely out-dated, with poor side-effect profiles, cumbersome logistics of administration, and inadequate efficacy. Historically, the impetus for a majority of neglected disease research was driven by early 20th-century colonialism, and in the post-colonial era, these diseases have been virtually ignored. Of the 1556 New Chemical Entities brought to market during the 30-year period from 1975 to 2004, only 20 — less than 0.02% — were for neglected diseases.
