Summit Announces BARDA Increases Award for Ridinilazole Clinical and Regulatory Development to up to $63.7 Million and Exercises Next Contract Option
- Summit Awarded $9.6M under Next Contract Option
- Total Committed BARDA Funding Now $53.6 Million
Oxford, UK, and Cambridge, MA, US, 18 June 2019 - Summit Therapeutics plc (NASDAQ: SMMT, AIM:SUMM), a leader in new mechanism antibiotic innovation, today announces that the Biomedical Advanced Research and Development Authority (‘BARDA') has increased the total value of its award for the clinical and regulatory development of Summit's precision antibiotic ridinilazole for the treatment of C. difficile infection (‘CDI') to up to $63.7 million. Under this award, BARDA has opted to exercise the next contract option for $9.6 million, which will support patient enrolment and dosing in the ongoing Phase 3 clinical trials of ridinilazole.
"The funding from BARDA is a testament to the promise of ridinilazole to address an important public health need in CDI. Through our ongoing landmark Phase 3 clinical programme, we aim to show that our microbiome preserving antibiotic is superior in sustaining cures compared to the current standard of care and so has the potential to be the front-line treatment option for patients with CDI," said Mr Glyn Edwards, Chief Executive Officer of Summit. "We are pleased with the excellent working relationship that has been formed between us over the last two years and thank BARDA for its continuing support of ridinilazole."
The total committed funding from the BARDA award under Contract No. HHS0100201700014C is now $53.6 million, with one final option remaining. The final option provides funding support for potential applications for marketing approvals of ridinilazole. The BARDA contract provides for a cost-sharing arrangement with the committed funding drawn down over a specified development period.

About C. difficile Infection
C. difficile infection is a serious healthcare threat in hospitals, long-term care homes and increasingly in the wider community with over one million estimated cases of CDI annually in the United States and Europe. CDI is caused by an infection of the colon by the bacterium C. difficile, which produces toxins that cause inflammation and severe diarrhoea, and in the most serious cases can be fatal. Patients typically develop CDI following the use of broad-spectrum antibiotics that can cause widespread damage to the natural gastrointestinal (gut) flora and allow overgrowth of C. difficile bacteria. The vast majority of patients are treated with broad-spectrum antibiotics, which cause further damage to the gut flora and are associated with high rates of recurrent disease. Reducing disease recurrence is the key clinical issue in CDI as repeat episodes are typically more severe and associated with an increase in mortality rates and healthcare costs. A study estimated that the total costs attributable to the management of CDI were approximately $6.3 billion per year in the United States.
Ridinilazole is an oral small molecule new mechanism antibiotic that is designed to selectively kill C. difficile, thereby preserving patients' protective gut microbiome and leading to sustained CDI cures. In a Phase 2 proof of concept trial in CDI patients, ridinilazole showed statistical superiority in sustained clinical response ('SCR') rates compared to the standard of care, vancomycin. In that trial, SCR was defined as clinical cure at end of treatment and no recurrence of CDI within 30 days of the end of therapy. Ridinilazole was also shown to be highly preserving of the gut microbiome in the Phase 2 proof of concept trial, which was believed to be the reason for the improved clinical outcome for the ridinilazole-treated patients. In addition, ridinilazole preserved the gut microbiome to a greater extent than the marketed narrow-spectrum antibiotic fidaxomicin in an exploratory Phase 2 clinical trial. Ridinilazole has received Qualified Infectious Disease Product ('QIDP') designation and has been granted Fast Track designation by the US Food and Drug Administration. The QIDP incentives are provided through the US GAIN Act and include a potential extension of marketing exclusivity for an additional five years upon FDA approval.
