U.S. Food and Drug Administration Released Notice For Hospital Mattress Safety

Health care facilities everywhere have been ramping up their disinfection practices in order to prevent the spread of infectious diseases. However, when it comes to hospital mattresses, one of the biggest vectors for spreading deadly bugs, efforts are still falling short.

With health care workers using chemicals that are intended for dry surfaces, the mattresses are harboring pathogens such as Clostridium difficile (C. diff), and, as Edmond A. Hooker, MD, DrPH, professor in the Department of Health Administration at Xavier University, pointed out at the 5th Annual International C. diff Awareness & Health Expo, regulatory agencies seem to have “turned a blind eye” to the issue.

Until now.

The US Food and Drug Administration (FDA) recently released a notice on how to keep hospital mattress covers safe.

In this notice, the FDA notes safety concerns regarding hospital mattress covers, particularly that over time they can “wear out and allow blood and body fluids to penetrate and get trapped inside mattresses.” They added, “If blood or body fluids from one patient penetrate and get absorbed in a mattress, the fluids can leak out the next time the mattress is used.” If that happens, the next patient runs the risk of coming into contact with these fluids, and thus, becoming infected with pathogens from the bed’s previous occupants.

The FDA reports that this is not the first time they acknowledged these concerns; they released a safety communication in 2013 to make health care workers aware of the issue. However, the problem of contaminated hospital mattresses persists.

“There is no question there has been report after report after report of, ‘We had this outbreak. We killed all these people.’ There was just a report that came out on 18 people who were sick in a French hospital; they were on beds manufactured here in America, and 4 people were killed before they finally realized that it was the mattresses. They took all of the mattresses out of service and stopped the outbreak,” Dr. Hooker told Contagion ® in an exclusive interview.

“There’s a reason that it’s an under reported problem; hospitals don’t want to say, ‘Hey, we just killed a bunch of people. We kill 29,000 people a year with C. difficile infections. Do you hear that? I mean, that’s like crashing a plane every day and we do nothing about it. We just act like it didn’t happen.”

In an effort to address the issue, the FDA has released recommendations based on Centers for Disease Control and Prevention (CDC) guidelines for environmental infection control in health care facilities; they include:

  1. Develop an inspection plan for all hospital mattresses and mattress covers in the facility. Learn the time of life for all mattresses/mattress covers by checking the manufacturer’s guidelines; follow any other recommendations that the manufacturers list. If you have any additional questions, contact the mattress manufacturer.
  2. Inspect each hospital mattress for visible signs of damage, which can include: cuts, tears, cracks, pinholes, snags, or stains. On a routine basis, remove mattress covers and check the inside. With the cover removed, check the mattress for wet spots, staining, or other signs of damage. Be sure to check all sides of the mattress as well as underneath. You will not be able to effectively inspect the mattress with the cover on.
  3. Remove any mattresses that are damaged, appear worn, or are visibly stained and immediately replace any mattress covers that are damaged.
  4. Maintain your mattresses and mattress covers by cleaning and disinfecting them “according to the manufacturer’s guidelines.” DO NOT stick needles into the hospital mattress through the cover, the FDA stresses.

“The FDA notice about mattress failures is an important first step. However, much more needs to be done. Most failures are not being reported to FDA, and the 700 reports that they have represents an industry-wide problem. Up to one-third of hospital mattresses currently in service in hospitals have failed. Also, the ones that have not failed are not being cleaned,”

Dr. Hooker stressed to Contagion ® in a follow-up interview. “These mattresses quickly get fissures and microscopic cracks that allow bacteria to remain on the surface during terminal cleaning. The next patient is then exposed to those bacteria and gets a hospital-acquired infection. The CDC needs to mandate better cleaning practices nationwide, which they can do.

The CDC needs to also mandate inspection of every mattress after every patient. Damaged mattresses should be removed from service immediately.”

Zinplava has been launched by MSD in the UK

MSD has launched Zinplava in the UK, offering patients a novel therapeutic option for the prevention of Clostridium difficile recurrence.

Zinplava (bezlotoxumab) is not an antibacterial and is not indicated to actually treat the infection, but is a monoclonal antibody designed to neutralise C. difficile toxin B, which can damage the gut wall and cause inflammation, leading to diarrhoea.

It is the first and only EC licensed non-antibiotic option indicated to prevent recurrence of Clostridium difficile infection (CDI) in high-risk adults.

Around one-in-four patients experience a recurrence after the initial episode, and more than 40 percent of these have further recurrence, highlighting the need for new options able to break the infection cycle.

Pivotal Phase III clinical studies showed the rate of infection recurrence through week 12 to be significantly lower in patients given Zinplava (17.4 percent and 15.7 percent) or Zinplava and actoxumab (15.9 percent and 14.9 percent) than those taking a placebo (27.6 percent) and (25.7 percent), respectively.

“Notably, bezlotoxumab reduces the risk of the recurrence of CDI for at least 3 months, compared with standard of care antibiotic therapy. This is welcome addition to our limited options to reduce the considerable morbidity and mortality associated with CDI,” commented Mark Wilcox, Professor of Medical Microbiology at the University of Leeds.

“Antimicrobial resistance is a key national issue and we hope with bezlotoxumab to not only help achieve a reduction in the number of recurrent episodes of CDI but also a reduction in the amount of antibiotic prescriptions that would otherwise be needed to treat these recurrent episodes,” added Dr Mike England, MSD’s Interim Medical Director.

Zinplava is administered as a single, one-off, one-hour intravenous infusion alongside standard-of-care antibiotic therapy for the treatment of CDI.

 

The American Gastroenterological Association (AGA) Fecal Microbiota Transplantation (FMT) National Registry Enrolls First Patient

Largest planned fecal microbiota transplantation (FMT) study enrolls first patient

The FMT National Registry also announces collaborations with American Gut and OpenBiome

The first participant has enrolled in the American Gastroenterological Association (AGA) Fecal Microbiota Transplantation (FMT) National Registry, which is planned to be the largest FMT study ever.

The AGA FMT National Registry — funded by the National Institutes of Health (NIH) and administered by the AGA Center for Gut Microbiome Research and Educationwill track 4,000 patients for 10 years after their FMT procedure, providing a wealth of data about the procedure’s effectiveness and both short- and long-term effects of FMT.

Fecal microbiota transplant is a medical procedure in which the stool from a healthy person is prepared and then put into the intestine of a sick patient. FMT is most commonly used to treat Clostridium difficile (C. diff) infection, if antibiotics have not been able to get rid of the infection.

“Today is an important milestone for the AGA FMT National Registry. What’s ahead is a significant repository of data for investigators working to advance FMT research, better information for physicians on when and how to use FMT, and reassurance for patients that we now understand the risks and benefits of this procedure,” said Gary D. Wu, MD, a principal investigator for the registry and founding chair of the AGA Center for Gut Microbiome Research and Education scientific advisory board. “We look forward to embarking on this comprehensive data collection project and are eager to share our findings with the public.”

First Patient Enrolled

The first patient enrolled in the FMT National Registry received a fecal transplant through the Gastroenterology Center of Connecticut/Medical Research Center of Connecticut by Paul Feuerstadt, MD, assistant clinical professor of medicine at Yale School of Medicine, New Haven, CT. The patient being treated had experienced multiple recurrences of C. difficile infection. As part of the registry,

Dr. Feuerstadt will follow up with the patient four times over the next two years and report back on the patient’s health post-FMT. The patient will also provide yearly reports for up to 10 years.

How Patients Can Take Part in the FMT National Registry

AGA expects 75 sites to be included in this registry. Visit ClinicalTrials.Gov <https://clinicaltrials.gov/ct2/show/study/NCT03325855?cond=FMT+National+registry&rank=1> on a regular basis to track new sites added to the registry. Patients should reach out to their health care provider to discuss participation in the registry.

Patients should first review AGA’s patient information on fecal microbiota transplantation (FMT) <http://www.gastro.org/info_for_patients/clostridium-difficile-106-fmt-details>.

UC San Diego to Build FMT National Registry Biobank

AGA is collaborating with the American Gut Project — an academic effort run by the laboratory of Rob Knight, PhD, professor and director of the Center for Microbiome Innovation at the University of California, San Diego — to build a biobank of stool samples from participants in the FMT National Registry. American Gut will receive stool samples from registry participants before and after their FMT. The microbiota will be sequenced in each sample, and remaining material will be frozen to be made available for future research. Eventually, this information could help doctors screen and select the best donor samples for individual patients.

OpenBiome Joins as a Registry Collaborator

AGA is also collaborating with OpenBiome, a public stool bank and nonprofit research organization that provides clinicians with rigorously screened, ready-to-use stool preparations for fecal transplant procedures. As the only public stool bank in the country, OpenBiome serves as the source of stool preparations for nearly 1,000 clinical partners performing FMT across the United States. For patients enrolled in the registry who receive OpenBiome FMT material, OpenBiome will provide screening information and samples to support the registry’s research analyses.

C Diff Foundation and C diff Survivors Alliance Network Share a Winter 2017 Bulletin

Greetings from the main office of the C Diff Foundation and the C diff Survivors Alliance Network located in New Port Richey, Florida.  As we close 2017 we mark the 5th anniversary of the two organizations. We want to share with you a summary and reflection on this year’s events and campaigns moving our mission forward and message delivered worldwide. The mission and promoting C.diff. Awareness has been shared this year with  listeners in over 25 Counties during Season III on C. diff. Spores and More Global Broadcasting Network (www.cdiffradio.com),  5,000+ visitors during global events, 9,600+ residents and business owners throughout villages and communities by our dedicated volunteer patient advocates, to over 1,000 clinicians who received up-to-date data expanding their knowledge during workshops and local symposiums offered worldwide, 3,000+ incoming calls received through the Nationwide Hot-Line 1-844-FOR-CDIF with the thousands of e-mails received seeking assistance.

After each event, workshop, meeting, introduction we thank the individuals for sharing  in five years of opportunity to provide life-saving data educating and advocating for C. difficile infection prevention, treatments, environmental safety and support worldwide.  The mission of the C Diff Foundation is the momentum of charity that has proven effective and grown over the past five years.  A single act of charity grows into more and greater charity worldwide.  The work each member of the C Diff Foundation, with hundreds of Volunteer Patient Advocates, promote the Foundation’s mission which never stops with a single act.  Instead, it builds, it grows, and it expands into an exponential impact of good in the world helping to save lives.  We thank you for your continued support and encourage you to continue your journey, proposing three verbs important to the C Diff Foundation and the C diff Survivors Alliance Network in general.

The first of these verbs is “to promote” C.diff. Awareness. It is the first step that opens doors in educating individuals, clinicians, communities in learning more about this life-threatening infection which causes a great amount of pain and suffering around the globe.  It is essential and it is the compass in reaching shared goals.

The second verb is “to heighten awareness” across the nation to continue proclaiming November Clostridium difficile infection awareness month. The Governors proclaimed November C. difficile (C.diff) infection awareness month in 2017 and we encourage them “to welcome” this proclamation in 2018 with more than a yearly executive order of greeting or inviting their residents to take notice.  We look forward to working with delegates, with your support, to make this proclamation statement nationwide and welcome the importance of the time, education, programs, and agenda in place addressing this life-threatening infection.  The C Diff Foundation advocates and supports the individuals and families suffering during and after being treated for a C. diff. infection.

Finally, the third verb that the C Diff Foundation and C diff Survivors Alliance Network propose is “to go.”  Here we are all challenged to do something big or small — with what we are able to do.  With the unity of members with volunteers with patients, families, and clinicians we can make a difference with enthusiasm and simplicity to get up and go.  We can do for others  today what we could not do for ourselves during our time of illnesses, during the long periods of isolation, during the losses, and during the pain and suffering.

As members of the C Diff Foundation we know that our enthusiasm  for our mission is the desire to bring awareness and promote C. difficile infection prevention, treatments, environmental safety and support worldwide.  We witness changes by the data and information being delivered within villages,  through major cities and in small communities — it is only by taking this path that we gain satisfaction knowing that the news delivered with enthusiasm “to promote, to heighten awareness and to go” with the members and volunteers in the C Diff Foundation and C diff Survivors Alliance Network creates positive results.

We are truly grateful for your continued dedication, efforts and support and thank you again for making this year’s November anniversary such a special occasion through the growth and advances made worldwide.   Let’s carry the mission into the New Year, carving new paths to witness the decline of newly diagnosed cases of Clostridium difficile (C.diff., C. difficile) infections and saving lives worldwide.

“None of us can do this alone ~ All of us can do this together.”

 

 

Summit Therapeutics Enters License and Commercialization Agreement with Eurofarama in Latin America to Summit’s Precision Antibiotic ridinilazole in Development for the Treatment of CDI

Summit Therapeutics —  the drug discovery and development company advancing therapies for Duchenne muscular dystrophy and Clostridium difficile infection (‘CDI’), announces that it has entered into an exclusive license and commercialization agreement granting Eurofarma Laboratórios SA (‘Eurofarma’) rights in Latin America (the ‘Licensed Territory’) to Summit’s precision antibiotic ridinilazole in development for the treatment of CDI.

Summit retains commercialization rights in all other countries.

ridinilazole is a targeted antibiotic that has the potential as a frontline therapy to treat initial infection and preserve patients’ microbiomes to reduce the rate of recurrent CDI. In a Phase 2 proof of concept trial in CDI patients, ridinilazole demonstrated statistical superiority in sustained clinical response (‘SCR’) rates compared to the standard of care, vancomycin.

ridinilazole is expected to enter Phase 3 clinical trials in the first half of 2018.

“Eurofarma’s established infrastructure and expertise in Latin America are ideally placed to commercialise our novel antibiotic, ridinilazole,” commented Glyn Edwards, Chief Executive Officer of Summit. “This agreement, combined with the recent contract award of up to $62 million from the US Government agency BARDA, will further support the Phase 3 clinical programme and regulatory development of ridinilazole. These partnerships endorse the potential of ridinilazole in the treatment of CDI, and move us a step closer to bringing this antibiotic to patients.”

Eurofarma is a multinational pharmaceutical company with headquarters in Brazil and operations in over 20 countries in South and Central America, the Caribbean and Africa. Eurofarma has a broad portfolio of products across multiple therapeutic areas including a focus in infectious diseases where it markets a number of antibiotics.

“CDI is a serious global healthcare threat including in Latin America,” added Martha Penna, P&D Vice-president of Eurofarma. “Through our interest in bringing innovative products to the region, we were impressed by the efficacy data from the ridinilazole Phase 2 programme and the differentiated profile of the drug. We believe it has the potential to address a major unmet need in CDI, and we look forward to working with Summit to bring ridinilazole to market for the benefit of patients.”

Under the terms of the licence and commercialisation agreement, Summit will receive an upfront payment of $2.5 million, and is entitled to receive a further $3.75 million in development milestones upon the achievement of staged patient enrolment targets in the planned Phase 3 clinical trials of ridinilazole. Summit is eligible to receive up to an additional $21.4 million through other development milestones, commercial milestones, and one-time sales milestones based on cumulative net sales up to $100 million in the Licensed Territory. Further, the agreement provides for product supply transfer payments expected to provide a return equivalent to a high single digit to low double-digit percentage of net sales. For each incremental $100 million in cumulative net sales achieved, Summit is entitled to a further milestone payment which, when combined with the aforementioned product supply transfer payments, is expected to provide a return equivalent to a mid- to high-teens percentage of net sales.

Eurofarma will be responsible for obtaining regulatory approval for ridinilazole in the Licensed Territory. Summit retains full responsibility for the clinical development of ridinilazole in all countries, and is responsible for obtaining regulatory approvals outside of the Eurofarma licensed territories.

A Form 6-K will be filed with the US Securities and Exchange Commission (‘SEC’) that contains additional information about the terms of the licence and commercialisation agreement with Eurofarma.

A copy of this Form 6-K will be available to download either from the Investors section of the Company website at www.summitplc.com or from the SEC website at www.sec.gov.

This announcement contains inside information for the purposes of Article 7 of EU Regulation 596/2014 (MAR).

About Ridinilazole

Ridinilazole is a small molecule precision antibiotic that Summit is developing for the treatment of CDI. In preclinical efficacy studies, ridinilazole exhibited a targeted spectrum of activity that combined a potent bactericidal effect against all clinical isolates of C. difficile tested with minimal impact on other bacteria that are typically found in the gut microbiome. 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, an orally administered small molecule, 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 an extension of marketing exclusivity for an additional five years upon FDA approval.

Rebiotix Announces Expansion of Phase 1 Study For Prevention of Recurrent C.diff. Infection Oral Capsule Microbiota Product RBX7455

Rebiotix Announces Expansion of Phase 1 Trial of the Company’s Oral
Capsule Microbiota Product, RBX7455, Following Successful Completion of
Initial Study Arms

Additional cohorts to examine potential of reduced dosing regimens of RBX7455 for the prevention of recurrent Clostridium difficile infection

Rebiotix Inc., a clinical-stage microbiome company
focused on harnessing the power of the human microbiome to treat challenging diseases, announced on November 30, 2017
an expansion of the investigator sponsored Phase 1 study of RBX7455 for the prevention of  recurrent Clostridium difficile (C. diff.) infection. The expansion follows the successful completion of the study’s two initial cohorts and is intended to explore reduced dosing regimens of RBX7455 in two new treatment arms. RBX7455 is a lyophilized, non-frozen oral capsule formulation of Rebiotix’s Microbiota Restoration Therapy™ (MRT), a standardized, stabilized drug technology that is designed to rehabilitate the human microbiome by delivering a broad spectrum of live microbes into a patient’s  intestinal tract via a ready-to-use and easy-to-administer format.
“Expansion of the Phase 1 study is a key advancement in the development of RBX7455 as it provides an opportunity to explore the potential efficacy of reduced dosing regimens of our oral capsule product in the prevention of recurrent C. diff. infection,” stated Lee Jones, president and CEO of Rebiotix. “RBX7455 is a ground-breaking product in that its oral capsule design is the first in the microbiome industry not requiring storage in frozen conditions. As such, patients are able to administer RBX7455 at home as they would a typical oral capsule medication, which potentially makes RBX7455 ideally suited for diseases where chronic or repeat dosing is required.”
The Phase 1 study of RBX7455 is an investigator sponsored, prospective, single center, proof of concept dosing study of RBX7455 for the prevention of recurrent C. diff. infection. The first two arms enrolled 10 patients per arm (20 total). The expansion of the Phase 1 study adds two additional arms, which will enroll approximately 10 patients per arm (20 total) with reduced dosing regimens from the 2
first two arms. Rebiotix expects data from the first two cohorts of the Phase 1 study of RBX7455 to be released publicly by mid-2018.
In addition to the expanded Phase 1 study of RBX7455, Rebiotix’s clinical development pipeline is highlighted by the company’s ongoing Phase 3 clinical trial of RBX2660 for the prevention of recurrent C. diff. infection. RBX2660 is the first and only microbiome drug to be tested in three separate Phase 2 trials, with more than 300 subjects having been treated with the microbial therapy.
Recently, Rebiotix announced the presentation of research from the RBX2660 Phase 2 program demonstrating measurable evidence of the drug’s rehabilitative effect on the human microbiome and the potential advantages of its broad consortia design.
Ms. Jones continued, “We look forward to the continued progress of the RBX7455 Phase 1 study as well as our Phase 3 study of RBX2660, our lead microbiome drug candidate. Importantly, since both drugs were developed with our MRT platform, we can leverage knowledge from the extensive RBX2660 clinical program, as well as research into the drug’s rehabilitative impact on the gut microbiome, to inform and expedite the development of RBX7455.”
About Rebiotix Inc.
Rebiotix Inc. is a late-stage clinical microbiome company focused on harnessing the power of the human microbiome to revolutionize the treatment of challenging diseases. Rebiotix possesses a deep and diverse clinical pipeline, with its lead drug candidate, RBX2660, in Phase 3 clinical development for the prevention of recurrent Clostridium difficile (C. diff.) infection.

U.S. Food and Drug Administration (FDA) Grants Orphan Drug Designation To Seres Therapeutics SER-287 For Treatment of Ulcerative Colitis In Pediatric Patients

Seres Therapeutics announced that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation to microbiome therapeutic candidate SER-287 for the treatment of Ulcerative Colitis (UC) in pediatric patients.

Orphan Drug Designation provides incentives designed to advance drug development for rare diseases or conditions that affect fewer than 200,000 people in the United States. The FDA’s designation of SER-287 follows a review of data which established a medically plausible basis for the use of SER-287 – specifically, the Phase 1b clinical data that highlights the potential of SER-287 as a novel treatment modality for patients suffering from UC.

Seres successfully completed a placebo-controlled Phase 1b study of SER-287 in patients with mild-to-moderate UC who were failing current therapies. SER-287 administration resulted in a dose-dependent improvement of both clinical remission rates and endoscopic scores, and demonstrated a very favorable safety profile. The Phase 1b results demonstrate the potential for SER-287 to provide an effective and safer alternative treatment modality for patients suffering from UC. SER-287 Phase 1b microbiome data are expected in early 2018.

“We are pleased to receive FDA Orphan Drug Designation for SER-287 and we look forward to advancing the program into further development for Ulcerative Colitis. Based on the highly encouraging Phase 1b clinical results and favorable safety profile, we intend to evaluate SER-287 in a pediatric UC population as part of our overall development plan. Safety is of particular importance to the pediatric population, and given the positive safety profile observed in our clinical trial to date, we believe our microbiome approach may be well suited to address this group,” said Roger J. Pomerantz, M.D., President, CEO and Chairman of Seres.

About SER-287

SER‐287 is a biologically sourced, oral formulation containing a consortium of live bacterial spores that is being developed for Ulcerative Colitis and other forms of inflammatory bowel disease. SER-287 is hypothesized to act through a novel mechanism of action by modulating the dysbiotic microbiome thereby reducing inflammation without immunosuppression effects. A healthy microbiome has been shown to maintain the integrity of the colonic barrier, reduce the signaling by pro-inflammatory molecules produced by certain bacteria, and induce regulatory T cells in the colon to modulate immune responses.1

About Ulcerative Colitis

Ulcerative Colitis is a serious chronic condition affecting approximately 700,000 individuals in the United States. The disease results in inflammation of the colon and rectum and can cause debilitating symptoms, including abdominal pain, bowel urgency, and diarrhea. Severe cases of Ulcerative Colitis may result in surgical removal of the colon.

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’ lead program, SER-109, has obtained Breakthrough Therapy and Orphan Drug designations from the U.S. Food and Drug Administration and is in Phase 3 development for multiply recurrent C. difficile infection. Seres’ clinical candidate SER-287 has successfully completed a Phase 1b study in patients with mild-to-moderate Ulcerative Colitis. Seres is also developing SER-262, the first ever synthetic microbiome therapeutic candidate, in a Phase 1b study in patients with primary C. difficile infection.
