New developments in the treatment of drug-resistant tuberculosis: clinical utility of bedaquiline and delamanid

As countries improve and scale up their diagnostic services, increasing number of patients with multidrug-resistant TB and extensively drug-resistant TB are identified. Bedaquiline and delamanid offer a real opportunity to improve the outcomes of these patients. After so many decades without new TB drugs the development of these two new medicines is an historic opportunity to gain ground in the fight against TB.

Abstract

The current treatment for drug-resistant tuberculosis (TB) is long, complex, and associated with severe and life-threatening side effects and poor outcomes. For the first time in nearly 50 years, there have been two new drugs registered for use in multidrug-resistant TB (MDR-TB). Bedaquiline, a diarylquinoline, and delamanid, a nitromidoxazole, have received conditional stringent regulatory approval and have World Health Organization interim policy guidance for their use.

As countries improve and scale up their diagnostic services, increasing number of patients with MDR-TB and extensively drug-resistant TB are identified. These two new drugs offer a real opportunity to improve the outcomes of these patients.

This article reviews the evidence for these two new drugs and discusses the clinical questions raised as they are used outside clinical trial settings. It also reviews the importance of the accompanying drugs used with these new drugs. It is important that barriers hindering the use of these two new drugs are addressed and that the existing clinical experience in using these drugs is shared, such that their routine-use programmatic conditions is scaled up, ensuring maximum benefit for patients and countries battling the MDR-TB crisis.
