ST. LOUIS, July 26, 2017 /PRNewswire/ -- Sequoia Sciences announced it has received Fast Track Designation from the U.S.
Sequoia's vaccine is designed to create an immune response preventing bacteria from colonizing the urinary tract, and it recently completed its first clinical trial in women. Of the 67 women enrolled in this first study, 30 had a two-year documented history of recurrent UTI. The vaccine was well-tolerated and generated a strong immune response.1 Based on the results of this first study, initiation of additional studies is ongoing including evaluating Sequoia's vaccine in patients requiring last-line of defense antibiotics. In granting Fast Track status, the FDA acknowledges that recurrent UTI caused by multidrug-resistant bacteria is a serious condition for which there is an unmet medical need.
"If approved, the vaccine could change the standard of care for recurrent UTI," said Gary Eldridge, president and CEO, Sequoia Sciences. "Since UTI are a primary source of sepsis, decreasing recurrent UTI may ultimately drive down rates of hospitalization, sepsis and associated in-hospital mortality."
Recurrent UTI Are Increasing Antibiotic Resistance
Antibiotics are the current standard of care for UTI patients, but repeated antibiotic use in this population contributes to the development of antibiotic resistance. Recurrent UTI patients frequently take daily antibiotics for one to four months or even longer. Each year, approximately 3 million patients in the U.S. and 10 million patients in North America, Europe and Japan experience recurrent UTI.2 It is estimated that about half of these patients have UTI caused by antibiotic-resistant bacteria.3
In a 2010 survey, 83 percent of urologists reported having administered intravenous antibiotics to recurrent UTI patients who were resistant to all available oral antibiotics.4 Antibiotic resistance among UTI patients has continued to increase. The North American Emerging Infections Network reported that about 80 percent of responding infectious disease physicians had treated a UTI caused by the most resistant bacteria, carbapenem-resistant Enterobacteriaceae (CRE).5 Even more alarming, in 2016 CRE among patients in long-term care facilities was found to be more widespread than predicted.6 There are currently no FDA-approved therapies to specifically treat recurrent UTI.
"Many of my patients with multidrug-resistant recurrent urinary tract infections have tried multiple antibiotics for years without success," said Liz D'Antonio, CRNP, director of clinical research Anne Arundel Urology. "A vaccine presents a new approach that could offer new hope for these patients. We eagerly await the results of the next studies as it hopefully moves toward approval."
Antibiotic Resistance — A Global Health Threat
Leading health care organizations, including Centers for Disease Control and Prevention, European Centre for Disease Prevention and Control, World Health Organization and Infectious Diseases Society of America (IDSA), have declared that antibiotic resistance is one of the most serious health threats facing the world.7 New rules requiring antibiotic stewardship programs in hospitals emphasize the need to use fewer antibiotics. Sequoia's investigational vaccine, if approved by the FDA, may help reduce the use of antibiotics and address this growing health threat.
