Our new mechanism antibiotics are designed to become the patient-friendly, new-era standard of care, by working in harmony with the human microbiome to treat prospective patients suffering from infectious disease, initially focusing on Clostridioides difficile infections (“CDI”) which is estimated to impact over 3 million patients worldwide annually. Commercialization of ridinilazole for the treatment and the reduction of recurrence of CDI is subject to regulatory approvals. The overriding objective of Summit Therapeutics is to create value for patients, hospital infectious disease caregivers, community-based infectious disease healthcare providers, as well as healthcare payors around the world.  Currently, Summit’s lead product candidate, ridinilazole, is engaged in two global Phase III trials, Ri-CoDIFy 1 & 2, each enrolling 680 patients vs. the standard of care (Vancomycin) for the treatment and reduction of recurrence of C. difficile infections.Summit’s vision and mission is to extend our pipeline through the development of new mechanism, narrow spectrum, microbiome-sparing antibiotics targeting C. difficile, Gram-negative Enterobacteriaceae, such as Escherichia coli and Klebsiella pneumoniae, and other bacterial infections with high unmet medical need.For more information, visit www.summittxinc.com and follow us on Twitter @summitplc.
