In 2014, Delamanid was conditionally approved for marketing by the European Medicines Agency and recommended for use in adult MDR-TB patients who cannot form an effective regimen due to drug resistance or tolerance reasons. In the same year, WHO recommended that Delamanid be conditionally used for long-term treatment of adult MDR-TB. In 2016, the WHO recommended widening the age range for Delamanid to 6-17 years old. In March 2018, Delamanid was listed in China.
