   Summit Presented In Vivo Proof of Concept Data for New Mechanism 
Antibiotics Targeting Enterobacteriaceae in Oral Session at ECCMID 2019 
 
 
   -- DDS-04 Series Cures Enterobacteriaceae Infection in Animal Model 
 
   -- Potential in Lung, Bloodstream and Urinary Tract Infections 
 
   -- Activity Shown Against Resistant and Non-Resistant Strains 
 
   -- Enterobacteriaceae are Gram-Negative Bacteria that Cause a Large Number 
      of Serious Infections 
 
 
   Oxford, UK, and Cambridge, MA, US, 15 April 2019 -- Summit Therapeutics 
plc (NASDAQ: SMMT, AIM: SUMM), a leader in new mechanism antibiotic 
innovation, presented in vivo proof of concept data for the DDS-04 
series of new mechanism antibiotics targeting Enterobacteriaceae in an 
oral session at the 29(th) European Congress of Clinical Microbiology & 
Infectious Diseases ('ECCMID') in Amsterdam. 
 
   Enterobacteriaceae are a family of Gram-negative bacteria responsible 
for a large number of severe and often deadly infections. In the data 
presented, a DDS-04 series compound cured infection in a 
translationally-relevant animal model of urinary tract infection, one of 
the major sites for Enterobacteriaceae infection. Therapeutic 
concentrations of the DDS-04 compound were also observed in other major 
sites in the animal model where life-threatening Enterobacteriaceae 
infections occur, including the lungs and the bloodstream. 
 
   "Patients with Enterobacteriaceae infections are increasingly at risk 
for poor outcomes due to the spread of antimicrobial resistance," said 
Dr David Roblin, President of R&D of Summit. "Mainstay treatments are 
losing their effectiveness, and patients do not have the luxury of time 
to fail antibiotic therapy. There is a pressing need for new, targeted 
Enterobacteriaceae antibiotics that can serve to improve patient 
outcomes." 
 
   The DDS-04 series acts via LolCDE, a novel bacterial target. The LolCDE 
site of DDS-04 series activity is conserved in the majority of 
therapeutically important Enterobacteriaceae, resulting in targeted 
spectrum compounds. With its new mechanism of action, the DDS-04 series 
was rapidly bactericidal and highly potent across globally diverse 
Enterobacteriaceae strains in research studies, which included 
multi-drug resistant isolates. Importantly, the DDS-04 series also 
showed low propensity for resistance development and did not show 
cross-resistance with existing classes of antibiotics, suggesting that 
DDS-04 compounds have the potential to overcome known resistance 
mechanisms. This profile makes the DDS-04 series attractive for further 
development for the treatment of Enterobacteriaceae infections. 
 
   "The DDS-04 series aligns with our antibiotic strategy. There is a clear 
opportunity to improve patient outcomes and a need for new mechanisms to 
deliver these improved outcomes and also to help address the spread of 
antimicrobial resistance," commented Mr Glyn Edwards, Chief Executive 
Officer of Summit. "We look forward to gathering further data to support 
the selection of a preclinical candidate from the DDS-04 series."

   About Enterobacteriaceae 
 
   Enterobacteriaceae are a family of Gram-negative bacteria responsible 
for severe and often deadly infections. They account for a significant 
fraction of cases across conditions, including complicated urinary tract 
infections, bloodstream infections and hospital-acquired pneumonias. 
Summit estimates there are more than 1 million infections in the US 
annually caused by Enterobacteriaceae across these three settings. 
Increasing resistance of Enterobacteriaceae has rendered many marketed 
antibiotics ineffective against these bacteria. Two of the most alarming 
antibiotic resistance trends are extended-spectrum beta-lactamase 
(ESBL)-producing Enterobacteriaceae and carbapenem-resistant 
Enterobacteriaceae (CRE). ESBL is an enzyme that allows bacteria to 
become resistant to a wide variety of penicillin and cephalosporin 
antibiotics. ESBL-producing Enterobacteriaceae account for an estimated 
26,000 infections annually in the US with 1,700 deaths, according to the 
US Centers for Drug Control and Prevention ('CDC'). CRE are resistant to 
nearly all existing antibiotics, including carbapenems which are 
considered the antibiotics of last resort. CRE account for an estimated 
9,000 infections per year in the US and 600 deaths, according to the 
CDC. 
 
   About Summit Therapeutics 
 
   Summit Therapeutics is a leader in antibiotic innovation. Our new 
mechanism antibiotics are designed to become the new standards of care 
for the benefit of patients and create value for payors and healthcare 
providers. We are currently developing new mechanism antibiotics for 
infections caused by C. difficile, N. gonorrhoeae and ESKAPE pathogens 
and are using our proprietary Discuva Platform to expand our pipeline.
