Mycobacterium tuberculosis: Products in our pipeline address tuberculosis (TB), multidrug-resistant TB (MDR-TB), and extremely drug-resistant TB (XDR-TB), diseases that affect 2.3 billion people, causing 10 million active infections and killing 2 million people yearly. Two of our drug candidates have completed phase 2 clinical trials (SQ109, sutezolid), one drug candidate (SQ609) is in preclinical development.

Helicobacter pylori: infections of the stomach that affect 3 billion people worldwide and cause gastric and duodenal ulcers and facilitate the development of gastric cancer. SQ109 demonstrated the ability to reduce a biomarker  in H. pylori infections in a proof-of-principle clinical trial in patients.

Clostridium difficile: hospital-based and community-acquired infection that can cause life-threatening diarrhea and is currently the #1 health threat in the U.S. (400,000 infections and 20,000 deaths yearly). SQ641 is a preclinical stage drug candidate for this indication.

Nontuberculous mycobacteria: infections responsible for pneumonias, Buruli ulcer, and Crohn's disease. SQ641 is a preclinical stage drug candidate for these indications.
