  New Guidelines Recommend Fidaxomicin for All Patients Who Are Suitable for
        Oral Antibiotic Treatment for Clostridium Difficile Infection

   Clostridium difficile infection (CDI), a potentially fatal disease, has
   surpassed MRSA as the leading cause of healthcare-acquired infections in
                              hospitals ^[1],[2]

The European Society of Clinical Microbiology and Infectious Diseases (ESCMID)
has published new guidelines recommending fidaxomicin for all CDI patients
suitable for oral antibiotic treatment. Specifically the guidelines recommend
fidaxomicin as first line therapy in CDI patients with first recurrence or
risk for recurrent disease and in patients with multiple recurrences of CDI.
The guidelines also recommend fidaxomicin in patients with severe disease and
non-severe CDI. ^[3]

CDI is one of the most common causes of antibiotic-associated diarrhoea and
severe cases can lead to bowel surgery and even death. ^[4] Hospital patients
with CDI are up to three times more likely to die in hospital (or within a
month of infection) than those without CDI. ^[5],[6] Recurrence is a major
challenge in CDI treatment. 25% of CDI patients suffer a recurrence within one
month ^[7],[8],[9] and patients who have already had one recurrence have a 40%
risk of a further episode of CDI. ^[10]

"One of the biggest challenges to optimal CDI management is recurrence,
therefore the significant reduction in disease recurrence by DIFICLIR compared
with vancomycin is an important step in reducing the morbidity and mortality
associated with CDI," comments Professor Oliver Cornely, University Hospital
Cologne, Germany. "I welcome these guidelines and believe implementation of
the recommendations will help to improve CDI care and reduce the burden on
both patients and healthcare systems."

Two large Phase III clinical studies comparing the efficacy and safety of
400mg/day oral fidaxomicin with 500mg/day oral vancomycin showed potential
advantages of fidaxomicin over vancomycin, the standard of care. ^[9],[11]
Patients were eligible to participate in these trials with a confirmed
diagnosis of CDI and included patients who were classified as having severe
CDI as well as patients for whom CDI is an especial risk such as those
patients who were elderly ^[11] or had concomitant diseases. ^[12],[13],[14]
Fidaxomicin significantly reduced the rate of CDI recurrence as compared with
vancomycin, with patients treated with fidaxomicin significantly more likely
than those receiving vancomycin to experience diarrhoea resolution without
recurrence within 30 days of therapy completion. ^[9],[11] Fidaxomicin also
met its primary endpoint of clinical cure rate, which was equivalent to that
of vancomycin. ^[9],[11]

Certain populations are at higher risk of CDI and are particularly vulnerable.
CDI can be associated with a mortality rate as high as 14% in elderly patients
^[15] and hospitalised cancer patients treated for CDI experience longer
hospital stays. ^[16] Progressive chronic kidney disease is associated with
increased time to resolution of diarrhoea, lower cure rates, and higher
incidence of recurrence in patients treated for CDI. ^[14] Patients in long
term care facilities are particularly at risk and CDI recurrence rates can be
as high as 50% over a six-month period when acquired in a long term care
facility. ^[17] Mortality rates in intensive care unit patients over the age
of 65 years have been reported to be as high as 45%. ^[18] In line with the
revised ESCMID treatment guidance document DIFICLIR is recommended for
patients who are suitable for oral antibiotic treatment in these vulnerable
patient sub-populations.

"CDI is potentially fatal and has a major impact on patients' health and
quality of life. We hope adherence to these recommendations will lead to
better management of CDI and the treatment of recurrence," said Ken Jones,
President and CEO of Astellas Pharma Europe Ltd. 

The previous ESCMID guidance document was issued in 2009 ^[19] and has been
widely applied in clinical practice. However, as new CDI treatments have been
developed an update of this document was necessary to further improve
uniformity of national CDI treatment policies in hospitals across Europe. To
produce the updated guidelines, ESCMID and a team of experts from 11 European
countries ran a computerised literature search to review randomised and
non-randomised trials investigating the effect of an intervention on the
clinical outcome of CDI. The revised 2013 guidelines provide an overview of
currently available CDI treatment options and evidence-based recommendations
on the treatment of CDI. ^[3]

NOTES FOR EDITORS

About CDI

CDI is a serious illness resulting from infection of the internal lining of
the colon by C. difficile bacteria. The bacteria produce toxins that cause
inflammation of the colon, diarrhoea and, in some cases, death. ^[20] Patients
typically develop CDI after the use of broad-spectrum antibiotics that disrupt
normal gastrointestinal flora, allowing C. difficile bacteria to flourish.
^[20],[21] CDI has an enormous impact on healthcare systems and infected
patients can stay in hospital an extra 1-3 weeks ^[22],[23],[24] at an
additional cost of up to €14,000, compared with patients without CDI. ^[25]

About the update of the ESCMID treatment guidance document for CDI

The ESCMID and an international team of experts from 11 European countries
developed the revised treatment guidance document with the objectives to
provide an overview of currently available CDI treatment options and to
develop an evidence-based update of treatment recommendations. Treatment
options that were reviewed include: antibiotics, toxin-binding resins and
polymers, immunotherapy, probiotics and faecal or bacterial intestinal
transplantation. ^[3]
