ThankYouInkPen

As Season II concludes, we wish to take this opportunity to sincerely thank each
and every guest for taking time out of their
busy schedule and joining us on Tuesday’s at
10:00a Pacific Time / 1:00p Eastern Time over the past seven months.

C. diff. Spores and More Global Broadcasting Network will be taking a break and will return to live broadcasting on  January 17th, 2017 with the Centers for Disease Control and Prevention (CDC) leading the way with our guest
Dr. Katherine Fleming-Dutra, Medical Officer, CDC’s Office of Antibiotic Stewardship.

A Prescription for Over-Prescribing: The Key to Fighting
Antibiotic Resistance

Dr. Fleming-Dutra is a medical epidemiologist with the Office of Antibiotic Stewardship in the Division of Healthcare Quality Promotion at the Centers Disease Control and Prevention (CDC).

Dr. Fleming-Dutra is a pediatrician and pediatric emergency medicine physician and has focused on infectious diseases epidemiology and antibiotic stewardship in the outpatient setting in her career at CDC.

Join Dr. Fleming-Dutra as she discusses a recent study published by the Journal of the American Medical Association, was released showing that at least 30 percent of all prescriptions written in doctors’ offices and emergency rooms are completely unnecessary. So how do we use these alarming results to transform the culture of over-prescribing Dr. Katherine Fleming-Dutra, M.D., will:

  • Give a detailed explanation of the study results, and provide an in-depth review of specific findings;
  • Highlight what CDC is doing to promote antibiotic stewardship across healthcare settings, and
  • Identify what clinicians, other health care professionals, and patients can do to improve antibiotic prescribing, therefore fighting antibiotic resistance.

Hard Facts: Deaths and illnesses are much higher than reports have shown. Nearly half a million Americans suffered from Clostridium difficile (C. diff.) infections in a single year according to a study released today, February 25, 2015, by the Centers for Disease Control and Prevention (CDC).

• More than 100,000 of these infections developed among residents of U.S. nursing homes.

Approximately 29,000 patients died within 30 days of the initial diagnosis of a C. diff. infection. Of these 29,000 – 15,000 deaths were estimated to be directly related to a
C. diff. infection. Therefore; C. diff. is an important cause of infectious disease death in the U.S.


Previous studies indicate that C. diff. has become the most common microbial cause of Healthcare-Associated Infections found in U.S. hospitals driving up costs to $4.8 billion each year in excess health care costs in acute care facilities alone. Approximately
two-thirds of C. diff. infections were found to be associated with an inpatient stay in a health care facility, only 24% of the total cases occurred in patients while they were hospitalized. The study also revealed that almost as many cases occurred in nursing homes as in hospitals and the remainder of individuals acquired the
Healthcare-Associated infection, C. diff., recently discharged from a health care facility.

This new study finds that 1 out of every 5 patients with the Healthcare-Associated Infection (HAI), C. diff., experience a recurrence of the infection and 1 out of every 9 patients over the age of 65 diagnosed with a HAI – C. diff. infection died within 30 days of being diagnosed. Older Americans are quite vulnerable to this life-threatening diarrhea infection. The CDC study also found that women and Caucasian individuals are at an increased risk of acquiring a C. diff. infection. The CDC Director, Dr. Tom Frieden, MD, MPH said, “C. difficile infections cause immense suffering and death for thousands of Americans each year.” “These infections can be prevented by improving antibiotic prescribing and by improving infection control in the health care system. CDC hopes to ramp up prevention of this deadly infection by supporting State Antibiotic Resistance Prevention Programs in all 50 states.”

“This does not include the number of C. diff. infections taking place and being treated in other countries.”  “The  C Diff Foundation supports hundreds of communities by sharing the Foundation’s mission and  raising C. diff. awareness to healthcare professionals, individuals, patients, families,  and communities working towards a shared goal ~  witnessing a reduction of newly diagnosed C. diff. cases by 2020 .”   ” The C Diff Foundation volunteer Advocates are greatly appreciated and continue to create positive changes by sharing their time  aiding in the success of our mission “Raising C. diff. awareness ”  worldwide.

C. diff. Spores and More “ spotlights world renowned topic experts, research scientists, healthcare professionals, organization representatives, C. diff. survivors, board members, and their volunteers who are all creating positive changes in the
C. diff.
community and more.

Through their interviews, the C Diff Foundation mission will connect, educate, and empower listeners worldwide.

Questions received through the show page portal will be reviewed and addressed  by the show’s Medical Correspondent, Dr. Fred Zar, MD, FACP,  Dr. Fred Zar is a Professor of Clinical Medicine, Vice Head for Education in the Department of Medicine, and Program Director of the Internal Medicine Residency at the University of Illinois at Chicago.  Over the last two decades he has been a pioneer in the study of the treatment of Clostridium difficile disease and the need to stratify patients by disease severity.

U.Va.’s Division of Infectious Diseases and International Health Could Lead To a New Treatment For C. diff. Infection (CDI)

 

Every year, about half a million patients are infected by Clostridium difficile, an otherwise harmless bacterium that can multiply out of control when the use of antibiotics upsets the balance of microorganisms in the gut. In 2011, about 15,000 deaths were directly attributable to the infection, according to a recent study by the federal Centers for Disease Control and Prevention (CDC).

Current probiotic treatments, which promote the growth of helpful bacteria, have been ineffective against the infection, also known as C. diff.

But work being done at U.Va.’s Division of Infectious Diseases and International Health could lead to a new treatment by the end of the calendar year, according to Dr. Bill Petri, chief of the division. That’s an unusually optimistic estimate in medical research, where scientific breakthroughs predate new treatments by several years.

“Some of these advanced probiotics are actually being tested today in the clinic for their role,” Petri said. “We’re actually participating in advanced clinical trials at U.Va.”

Immunologist Erica L. Buonomo was the driving force behind the new discovery, Petri said, which has to do with the role of white blood cells in protecting against C. diff.

Buonomo found that a particular type of white blood cells, called eosinophils, act as a barrier against the infection, which breaks down the lining of the gut. These eosinophils are recruited by a protein called IL-25. A serious C. diff infection kills eosinophils, allowing the bacteria to enter the gut.

The researchers found that gut bacteria stimulate the production of IL-25, so the right probiotic could help with the production of protective eosinophils.

“We identified a pathway in the immune response that reduces the severity of an infection,” Buonomo said. “When we activate this pathway, we find mice are a lot less sick.”

The discovery would be especially helpful for elderly patients, who are most at risk. It also could have larger implications in the world of microbiology.

Eosinophils are best known for their role in allergic reactions and asthma attacks, when a high number of eosinophils cause inflammation.

The function of these cells was not entirely clear before Buonomo’s discovery. She believes this knowledge could help doctors fight other types of gastrointestinal disorders, such as irritable bowel syndrome.

U.Va. is now working on a probiotic with a Boston-based firm called Seres Therapeutics 

The finished product will be tested in Charlottesville, Petri said.

Seres Therapeutics, Inc. Announced That It Has Initiated a Phase 1b Clinical Trial Evaluating SER-262 In Patients With Primary C. diff. Infection (CDI)

Seres Therapeutics Inc.  a leading microbiome therapeutics company, announced today that it has initiated a Phase 1b clinical trial evaluating SER-262 in patients with primary Clostridium difficile infection (CDI).

SER-262 is an Ecobiotic® rationally-designed, fermented microbiome therapeutic derived by a manufacturing process that does not require human donor material. SER-262 is the first synthetically-derived and designed microbiome therapeutic ever to reach clinical-stage development.

“We intend to continue to utilize our platform technology and unique knowledge of bioinformatics, microbiology, manufacturing and regulatory requirements to develop additional rationally designed microbiome therapeutics for serious diseases in each of our three therapeutic franchises: infectious disease, immunology and metabolic disease.”

SER-262, an oral capsule, contains a consortium of twelve bacterial strains in spore form. The strains included in SER-262 were selected based on multiple criteria including analysis of human microbiome data, efficacy in animal models of CDI, and bacterial strain level characterization.1 The composition of SER-262 was selected among Seres’ field-leading human microbiome library containing over 14,000 well-characterized strains of bacteria.

The SER-262 Phase 1b study, a 24-week randomized, placebo-controlled, dose escalation study is expected to enroll approximately 60 patients who have experienced a first episode of CDI. The primary endpoint of the study will compare the CDI recurrence rate between the SER-262 and placebo groups at up to 8 weeks after dosing.

Approximately 640,000 and 820,000 individuals in U.S. each year experience a primary occurrence of CDI, and about 25 percent will suffer from a subsequent recurrence.

“Advancing SER-262 to the clinic is a landmark event for Seres and the microbiome field in general. The SER-262 program has demonstrated our ability to rapidly develop a new class of synthetic microbiome therapeutics comprised of rationally designed bacterial compositions,” said Roger Pomerantz, M.D., President, Chief Executive Officer and Chairman of Seres. “We intend to continue to utilize our platform technology and unique knowledge of bioinformatics, microbiology, manufacturing and regulatory requirements to develop additional rationally designed microbiome therapeutics for serious diseases in each of our three therapeutic franchises: infectious disease, immunology and metabolic disease.

With the initiation of the SER-262 Phase 1b study in primary CDI, and the ongoing SER-109 Phase 2 study in multiply recurrent CDI, Seres now has ongoing microbiome clinical programs across the entire CDI population. Initial study results from the SER-109 Phase 2 study are expected in mid-2016.

About Seres Therapeutics
Seres Therapeutics, Inc. is a leading microbiome therapeutics platform company developing a novel class of biological drugs that are designed to treat disease by restoring the function of a dysbiotic microbiome, where the natural state of bacterial diversity and function is imbalanced. Seres’ most advanced program, SER-109, has successfully completed a Phase 1b/2 study demonstrating a clinical benefit in patients with recurring Clostridium difficile infection (CDI) and is currently being evaluated in a Phase 2 study in recurring CDI.

The FDA has granted SER-109 Orphan Drug, as well as Breakthrough Therapy, designations. Seres’ second clinical candidate,

SER-287, is being evaluated in a Phase 1b study in patients with mild-to-moderate ulcerative colitis (UC).

Microbiome – C. diff. Treatments On The Horizon

 

 

 

PROBIOTICS:

Pick a disease or disorder, and somebody, somewhere, has said that a probiotic supplement—an over-the-counter, unregulated pill usually filled with a single strain of friendly gut bacteria—might cure it, whether it’s cancer, obsessive-compulsive disorder, or a yeast infection.

But there’s very little evidence that probiotic supplements do any good. “There’s a lot of promise here but not a lot of proof yet,” said Cliff McDonald, associate director for science at the Centers for Disease Control and Prevention’s Division of Healthcare Quality Promotion.

 #####

CDC Reports:

Half a million people a year are infected with C. diff in the U.S., the CDC estimates, with 29,000 annual deaths related to the diarrheic bacterium. More than 65 percent of C. diff infections involve exposure in a health-care facility, according to a 2015 study, creating more than $4.8 billion in excess health-care costs at acute-care facilities alone.

C. diff. Treatments On The Horizon:

To Learn More About ALL C. diff. Clinical Trials In Progress Click On The Following Link:

https://cdifffoundation.org/clinical-trials-2/

 

Seres Therapeutics, a microbiome-based biopharmaceutical company in Cambridge, Mass., is developing a pill, subject to a rigorous approval process under the Food and Drug Administration, to tackle recurrent Clostridium difficile. (The digestive system’s microbiome is the community of healthy gut bacteria that normally reside in the body.)

Seres aims to put the science behind a proven treatment of recurrent C. diff, fecal transplants, in a pill, which wouldn’t require a colonoscopy. Like probiotic supplements, it’s a gut bacteria product. Unlike the supplements, by the time it’s available it will have gone through the FDA wringer. It will contain about 50 strains of bacteria proven effective in treating C. diff and will require a doctor’s prescription.

Recurrent C. diff is an obvious entry point for Seres, said Chief Executive Officer Roger Pomerantz. “We asked, what is the lowest-hanging fruit?” But it’s hardly the end. The company has built a microbiome library of 14,000 strains of human bacteria it hopes will help it treat a range of diseases, eventually without needing feces at all.   Seres has embarked on the research with some pretty lofty goals, including finding treatments for obesity, liver disease, and cancer. It has partnerships with Massachusetts General Hospital, the Mayo Clinic, Memorial Sloan Kettering Cancer Center, and other respected medical institutions.  “We will figure out exactly what’s wrong with the microbiome, design a drug, and then pull the organisms out with our library, never touching a human donation,” Pomerantz said.    Seres’s lead product candidate, SER-109, will treat recurrent C. diff with four capsules taken orally instead of with transplants. While fecal matter is the raw material for the pills, the final product consists only of the spores necessary to treat the infection, which will have been extracted and purified.  SER-109 is expected to become the first oral microbiome therapy approved by the FDA, though Seres declined to predict exactly when it will arrive. Results from the latest trials are due by midyear, and Phase 3 trials are scheduled to follow later in the year. Seres hopes to follow up quickly with SER-287, a drug to treat ulcerative colitis, which could be the first microbiome drug to treat a chronic disease, and SER-262, to treat primary C. diff before it turns into the recurrent kind.

Other companies are racing to collect enough data for FDA approval, but right now Seres, which is publicly traded, looks to be the one to beat. “Seres is probably going to be the first one that’s going to knock at the FDA’s door,” said Mohan Iyer, chief business officer at Second Genome, a microbiome company studying how to treat disease with the compounds produced by gut bacteria instead of the gut bacteria themselves.

“SER-109 is poised to be first-in-class among fecal microbiota transplant-derived drugs,” Joseph Schwartz, an analyst at Leerink Partners, wrote in a May report. The report says the latest trial results “wowed the Street” but warns that the company could still be held back by “disappointing clinical data” and obstacles in the regulatory process.

#########

Another top contender is Rebiotix. Its RBX2660 is also designed to treat recurrent C. diff but, unlike SER-109, is administered with an enema; an oral version is in development. The treatment also differs significantly from Seres’s in formulation, including thousands of kinds of microbes from the donor’s stool, compared with SER-109’s 50 or so, as many as could be preserved and some of which haven’t even been identified.

“We make sure we have a minimum concentration of certain kinds that we know the patients lack,” CEO Lee Jones said. “But we don’t identify all of them. There’s no way to do that.” A recent study estimated that 1014 bacteria are in the human gut, most of which have never been isolated. Jones said the drug could hit the market by 2018.

######
  • UPDATES:

The medications have been shown to be similarly effective—with no C. diff-associated diarrhea for 29 of 30 of Seres’s patients  and  27 of 31 of Rebiotix’s, in the companies’ latest results—and equally safe. Adverse reactions for both are limited to such problems as moderate diarrhea and abdominal cramping, which could be from the C. diff itself. Both have been designated as “breakthrough therapies” by the FDA, allowing for an expedited approval process, and both are likely soon to provide an at-home alternative to fecal transplants.

#####

Point Of View:

“I don’t know who is going to make it across the line first,” said Gail Hecht, director of gastroenterology and nutrition at Loyola University Medical Center and chairwoman of the American Gastroenterological Association for Gut Microbiome Research & Education. Hecht has attended a Seres advisory board meeting but doesn’t have a financial interest in the company. “It is indeed a race,” she said.

Seres does have at least one distinct market advantage. “Patients have different preferences,” Hecht observes, but “in general, people don’t particularly like enemas.”

#####

Human Fecal Transplants:

For nearly two thousand years, doctors have looked to this unlikeliest of places for medicine. One of the earliest documented applications is from the fourth-century Chinese medical doctor Ge Hong, whose “yellow soup” recipe to treat diarrhea included a healthy person’s dried or fermented feces. Sixteen hundred years later, in 1958, patients infected with C. diff received the first known human fecal transplants.

Stool Bank Information: 

Today the effectiveness of fecal transplants (formally known as fecal microbiota transplants) to treat recurrent C. diff is supported by a long list of studies, with researchers attributing the results to the restoration of the microbiome. OpenBiome, a nonprofit stool bank, shipped 1,828 treatments in 2014, a number that ballooned to 7,140 treatments in 2015 and looks to be eclipsed this year, with 4,323 treatments shipped to its clinical partners through May 31. And these numbers don’t take into account the transplants performed through directed fecal donations.
