The Long Wait for a New Drug for Human African Trypanosomiasis

Catriona H Baker et al. Trends Parasitol. 2018 Oct.

Abstract

Human African trypanosomiasis (HAT) is responsible for around 3000 reported cases each year. Treatments for HAT are expensive and problematic to administer, and available drugs are old and less than ideal, some with high levels of toxicity that result in debilitating and, in some cases, fatal side effects. Treatment options are limited, with only one drug, eflornithine, introduced in the last 28 years. Here we examine the limitations of current chemotherapeutic approaches to manage HAT, the constraints to new drug development exploring drug failures and new drugs on the horizon, and consider the epidemiological, political, social, and economic factors influencing drug development.

Keywords: T. b. gambiense (g-HAT); T. b. rhodesiense (r-HAT); drug discovery; human African trypanosomiasis (HAT); sleeping sickness; tsetse.
