 to NTM lung disease, some of which were terminated prior to completion due to clinical resistance observed in a small number of patients in one of the two Phase 2 clinical trials. Epetraborole was not tested by Anacor or GSK in patients with NTM lung disease or in combination with other antimicrobial agents.

Epetraborole Regulatory Exclusivity

As an orphan and QIDP-designated product, if approved in the United States for use in patients with treatment-refractory MAC lung disease, it is possible we could obtain up to 12 years of regulatory exclusivity, independent of any applicable patent protection. If approved in Japan, we believe we could obtain at least eight years of exclusivity, independent of any applicable patent protection that we may acquire.

AN2-502998 Chagas Disease

Chagas disease is caused by the parasite Trypanosoma cruzi, which spreads via triatomine bugs (vector), a subspecies of blood-feeding insects more commonly known as “kissing bugs” because they tend to bite people on the face and lips. T. cruzi is also transmitted congenitally from infected mothers to their babies, through consumption of contaminated food or beverages, and via blood transfusions and organ transplants. While the disease can progress slowly, chronic infection almost inevitably results in irreparable damage to heart and digestive system tissues. If untreated, infection is lifelong and can be life threatening. Chagas disease kills more people in Latin America than any other infectious disease–including malaria, tuberculosis, and HIV—and is one of the major causes of infection-induced myocarditis or cardiomyopathy worldwide. An estimated 30% of Chagas patients develop chronic and often severe heart disease that leads to premature death. 

According to the World Health Organization, approximately 6-7 million people worldwide are estimated to be infected with the parasite T. cruzi, mostly in Latin America. An increasing number of cases of Chagas are also being documented in the United States of America and Europe. In the United States, the CDC estimates that there more than 300,000 people infected with T. cruzi, most of whom were infected in Chagas-endemic regions in Latin America. 

Chagas disease presents in an acute phase (~2 months after infection) and a chronic phase, where the T. cruzi parasites are hidden mainly in the heart and digestive muscles. For over 50 years, two nitroheterocyclic compounds, benznidazole and nifurtimox, have
