Da Volterra Shared Results From Phase I Clinical Trial of DAV132 to Prevent Gut Microbiome Disruption Caused by Antibiotics and Prevent C. diff. Infections

DAV132 is a first-in-class product to protect the microbiome during antibiotic treatments and prevent Clostridium difficile infections.

French biotech Da Volterra is developing products to fight the rapidly rising rates of antibiotic resistance. During a Phase I study, the company’s medical device, DAV132, was used with the antibiotic, moxifloxacin, and successfully protected the intestinal microbiota from antibiotic residues. Overall, the product managed to reduce exposure of the microbiota to the antibiotic by 99% and maintain 97.8% of the microbiome’s genetic richness without affecting the drugs therapeutic efficacy.

In a randomized, controlled clinical trial performed in 44 healthy human volunteers, DAV132 was used in association with moxifloxacin, a widely used fluoroquinolone antibiotic. It was demonstrated that DAV132 is able to effectively capture residual antibiotics in the colon and reduce their concentration to very low levels. DAV132 reduced exposure of the intestinal microbiota to moxifloxacin by 99%. Meanwhile the plasma concentration of the antibiotic was essentially unaffected by the co-administration DAV132, meaning that its therapeutic efficacy will be maintained.

The ability of DAV132 to protect the intestinal microbiome was explored by identifying changes in bacterial gene richness as well as a detailed statistical analysis of the evolution of bacterial species throughout the study. In volunteers who received moxifloxacin alone, gene richness was drastically diminished to 54.6% of baseline after antibiotic treatment and failed to return to baseline even one month after treatment; 39% of bacterial species identified in the intestinal microbiota were affected. The co-administration of DAV132 with moxifloxacin largely protected the intestinal microbiome from disruption (97.8% of baseline for bacterial gene richness, and 93% of bacterial species protected).

The primary endpoints for the study were fully achieved and DAV132 showed an excellent tolerability profile.

Annie Ducher MD, Chief Medical Officer of Da Volterra, declared: “This clinical study is indicative of the potential of DAV132 to become one of the first preventative solutions to protect the intestinal microbiome and further avoid the detrimental consequences of antibiotic treatments, such as Clostridium difficile infections, for patients. We look forward to advancing the development of DAV132 in a pivotal patient study in 2018.”

Jean de Gunzburg PhD, Chief Scientific Officer of Da Volterra, added: “This study constitutes the first scientific demonstration of the protection of the intestinal microbiome from dysbiosis caused by a fluoroquinolone antibiotic treatment; our data suggests that this effect should be extendable to many different antibiotics from several therapeutic classes. The metagenomics analysis is outstanding and thoroughly convincing that DAV132 is highly effective at protecting the commensal bacteria in the intestines.”

CutisPharma Announces FDA Approval Of FIRVANQ™ (vancomycin hydrochloride) for Oral Solution for Treatment of Clostridium difficile Associated Diarrhea (CDAD) and Staphylococcus aureus Colitis

CutisPharma Announces FDA Approval Of FIRVANQ™ For Treatment Of  Clostridium Difficile Associated Diarrhea (CDAD) And Staphylococcus Aureus Colitis

 

FDA-approved vancomycin oral liquid therapy expected to improve patient access and reduce pharmacist  burden by no longer having to compound liquid formulations

CutisPharma announced today, January 29, 2018,  that the US Food and Drug Administration (FDA) has approved FIRVANQ™ (vancomycin hydrochloride) for oral solution, for the treatment of Clostridium difficile associated diarrhea and enterocolitis caused by Staphylococcus aureus, including methicillin-resistant strains.

“We are pleased to announce the FDA approval of FIRVANQ,” said Neal I. Muni, MD, MSPH, Chief Executive Officer of CutisPharma. “FIRVANQ’s approval is an important step forward to providing patients the only FDA-approved vancomycin oral liquid treatment option for Clostridium difficile associated diarrhea, a life-threatening condition that affects over a half-million patients in the United States annually.”

Upon its launch, which is targeted to be April 2, 2018, FIRVANQ™ will replace CutisPharma’s FIRST®-Vancomycin Unit-of-Use Compounding Kit, which has been available to pharmacists that need a convenient, accurate, and compliant way to compound vancomycin oral liquid therapy. FIRVANQ™ will be commercially available in 25 mg/mL and 50 mg/mL strengths in convenient 150 mL and 300 mL sizes.  FIRVANQ™ is designed to be easy to use and has the potential to be a cost-effective alternative to existing vancomycin therapies.

“As a practicing infectious disease physician treating many patients with CDAD, having an FDA-approved vancomycin oral liquid formulation that is affordable and accessible to my patients is very beneficial,” said Stuart Johnson, MD, Loyola University Medical Center. “Patient access is currently limited by the fact that only a select few pharmacies perform compounding in the outpatient setting these days, given the many new regulations in place.  Availability of an FDA-approved vancomycin oral liquid treatment will effectively allow any pharmacy to stock this therapy, and hopefully encourage third-party payer reimbursement, significantly improving accessibility and convenience for patients.”

About CutisPharma

CutisPharma, Inc., based in Wilmington, Mass., is a privately held, specialty pharmaceutical company that has been the industry leader for 20 years in providing innovative solutions to pharmacists.  CutisPharma’s FIRST® Unit-of-Use Compounding Kits have benefited millions of patients who are unable to swallow conventional oral dosage forms such as tablets and capsules and whose needs are not served by commercially available therapies. The Company’s first FDA-approved Kit will allow significantly broader patient access, convenience to pharmacists and patients alike by reducing the need for compounding, and serve as a potential cost-saving option to existing treatments.  For more information, visit www.cutispharma.com

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.

 

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.”

 

 

Seres Therapeutics SER-109 Phase 3 Clinical Study For Recurrent C. diff. Infection Initiated

Seres Therapeutics Initiates SER-109 Phase 3 Study in Patients with Multiply

Recurrent C. difficile Infection

 

Jun. 12, 2017– Seres Therapeutics, Inc.

announced the initiation of its Phase 3 SER-109 clinical study (ECOSPOR III) in patients with multiply recurrent C. difficile infection. Based on recent interactions with the U.S. Food and Drug Administration (FDA), ECOSPOR III will now be designated a Phase 3 trial and the company expects that this single pivotal study may support SER-109 registration and approval.

“We are extremely pleased to be able to initiate the SER-109 Phase 3 ECOSPOR III study. If ECOSPOR III is successful, we believe this study could serve as the basis for SER-109 approval. Our goal is to have SER-109 approved as the first microbiome drug in this new field of medicine, and the first for patients with multiply recurrent C. difficile infection, an area of very high unmet need for patients in the U.S. and around the world,” said Roger J. Pomerantz, M.D., President, CEO and Chairman of Seres.

The ECOSPOR III Phase 3 study design incorporates direct learnings from prior SER-109 development efforts, as well as helpful feedback obtained from the FDA and study investigators. The study is expected to enroll approximately 320 patients with multiply recurrent C. difficile infection, randomized 1:1 to either SER-109 or placebo. The study is sized to contribute to an adequate safety database that may support product licensure. ECOSPOR III will utilize more than 100 clinical sites across the U.S. and Canada. The study’s primary endpoint will compare the reduction of C. difficile recurrence rates in subjects who receive SER-109 verses placebo at up to eight weeks after dosing.

The initiation of the SER-109 Phase 3 ECOSPOR III study triggers a $20 million milestone payment under the company’s previously announced development and commercialization collaboration agreement with Nestlé Health Science. In partnership with Nestlé Health Science, Seres plans to accelerate interactions with European regulatory agencies in the coming months to establish a path toward SER-109 product approval across Europe.

About SER-109 and C. difficile Infection

SER-109, an oral capsule, is Seres’ lead Ecobiotic® microbiome therapeutic for the treatment of multiply recurrent C. difficile infection. SER-109 is a biologically sourced consortium of bacterial spores designed to catalyze a shift in a dysbiotic gastrointestinal microbiome to a healthier state. The FDA has granted SER-109 both Breakthrough Therapy and Orphan Drug Designations.

C. difficile infection is one of the top three most urgent antibiotic-resistant bacterial threats in the United States according to the Centers for Disease Control.

Rebiotix Treats First Patient in Phase 1 Study of RBX7455, an Orally Delivered Broad-Spectrum Non-Frozen MicrobiotaROSEVILLE, Minn., Jan. 4, 2017

 

Rebiotix Inc., a clinical-stage biotechnology company focused on harnessing the power of the human microbiome to treat challenging diseases, announced today that the first patient has been treated in a Phase 1 study of RBX7455 for the prevention of recurrent Clostridium difficile (C. diff.) infection.

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.

RBX7455 lyophilized capsules remove the need for patients to keep the product frozen or refrigerated.

This prospective, single center, two-arm Phase 1 study is a proof of concept dosing study of RBX7455 for the prevention of recurrent C. diff. infection, an increasingly difficult-to-resolve intestinal infection that causes approximately 29,000 deaths in the U.S. each year.1 It is also the first clinical study of an oral microbiota therapy that allows the patient to take the medication at home.

  • RBX7455 requires no special handling or storage needs for patients. The study will enroll approximately 20 patients at a single U.S. site and is being conducted by the Mayo Clinic, a nonprofit worldwide leader in medical care, research and education.

“New therapies are urgently needed to prevent recurrent C. diff., a debilitating, costly and potentially life-threatening infection,” said Dr. Sahil Khanna, Assistant Professor of Medicine, Department of Gastroenterology and Hepatology, Mayo Clinic, who is leading the study. “RBX7455 not only provides standardized and stabilized human microbes orally, but may provide several advantages in terms of patient dosing and therapy accessibility since no freezing or refrigeration is needed when the patient takes the product home.”

The initiation of the Phase 1 study of RBX7455 enhances Rebiotix’s clinical pipeline of human microbiome-directed drug candidates. The Company’s lead drug candidate, RBX2660, recently completed a Phase 2b randomized, double-blind placebo-controlled trial examining the efficacy and safety of the microbiota restoration therapeutic as a prevention for recurrent C. diff. infection after a standard of care course of antibiotics (PUNCH™ CD2).

“Dosing the first patient in the Phase 1 study of RBX7455 is a significant milestone for Rebiotix as it solidifies our position as the most clinically advanced microbiome company in the industry, while showcasing the potential of our MRT platform to create new solutions for challenging diseases through standardized microbiota-based drug development,” stated Lee Jones, president and CEO of Rebiotix. ”

RBX7455 is a potentially ground-breaking product for Rebiotix and the entire microbiome industry in that the lyophilized oral capsules do not need to be kept frozen and thus can be stocked in a pharmacy with no special handling or storage needs. As such, RBX7455 offers the unique opportunity to introduce live microbial therapy as a potential treatment for numerous diseases where chronic or repeat dosing is required.”
