SQ109 is a novel 1,2-ethylene diamine small molecule drug with 3 unique mechanisms of action that are distinct from other antibiotics used for the treatment of tuberculosis (TB). In laboratory studies, SQ109 demonstrated excellent activity against both drug susceptible and multidrug-resistant M. tuberculosis, including extensively drug-resistant TB strains. SQ109 also enhanced activity of anti-tuberculosis drugs isoniazid, rifampicin, and bedaquiline and shortened by >30% the time required to cure mice of experimental TB. SQ109 could replace one or more of the current TB drugs, simplify therapy, and shorten current treatment time. Infectex, Ltd, licensed the rights to develop and commercialize SQ109 in the Russian Federation and Commonwealth of Independent States from Sequella, Inc., in 2011. SQ109 is currently under Sequella’s US IND and completed three Phase 1 studies in the U.S. and two Phase 2 studies in drug-sensitive TB patients in Africa in addition to the Phase 2b-3 study in Russia.
