U.S. Food and Drug Administration (FDA) Has Accepted 2 New Drug Applications (NDA) for DIFICID (fidaxomicin) In Children Aged Six Months Or Older

OCTOBER 2019

Merck

Known as MSD outside the United States and Canada

announced the U.S. Food and Drug Administration (FDA) has accepted for review a New Drug Application (NDA) for DIFICID ® (fidaxomicin) for oral suspension, and a supplemental NDA (sNDA) for a new indication for use of DIFICID tablets and oral suspension for the treatment of Clostridium (also known as Clostridioides ) difficile infections (CDI) in children aged six months or older. Both applications have received a priority review classification by the FDA. The Prescription Drug User Fee Act (PDUFA), or target action date for both applications, is set for Jan. 24, 2020. The investigational pediatric indication for DIFICID was granted Orphan Drug Designation (ODD) in 2010.

“Evidence indicates the increasing incidence of C. difficile -associated diarrhea among hospitalized children 1,” said Dr. Nicholas Kartsonis, senior vice president, Clinical Research, infectious diseases and vaccines, Merck Research Laboratories. “The filings for the pediatric indication for the new investigational oral suspension formulation of DIFICID, as well as for DIFICID tablets, underscore Merck’s focus and dedication to developing infectious disease treatments for those with unmet needs.”

The sNDA is based primarily on results of the Phase 3 SUNSHINE study 2, which were presented as part of the Late Breaker Oral Abstracts on Emerging Infections at IDWeek 2018 in San Francisco, California.

About DIFICID (fidaxomicin)

DIFICID is a macrolide antibacterial medicine indicated in adults (18 years of age or older) for treatment of Clostridium difficile -associated diarrhea (CDAD). To reduce the development of drug-resistant bacteria and maintain the effectiveness of DIFICID and other antibacterial drugs, DIFICID should be used only to treat infections that are proven or strongly suspected to be caused by Clostridiumdifficile. DIFICID is contraindicated in patients who have known hypersensitivity to fidaxomicin or any other ingredient in DIFICID. DIFICID should only be used for the treatment of C. difficile-associated diarrhea. DIFICID is not effective for the treatment of other types of infections due to minimal systemic absorption of fidaxomicin.

Merck and Premier Applied Sciences Will Develop Software To Provide C.difficile Infection Education and Provide Surveillance

Merck & Co is working a major US hospital provider on a new software system that could help tackle the threat from healthcare-associated infections, the leading HAI:   C. diff.  infections.

 

 

 

The pharma company’s deal with Premier will see the partners develop and test the combination of a software-based platform and a coordinator to provide surveillance, consultation, support and education to patients with Clostridium difficile infection (C. diff).

Sam Bozzette, MD, chief scientist of Premier’s retrospective and interventional research division Premier Applied Sciences, said: “By increasing clinician and patient knowledge of this often prolonged, and sometimes deadly infection, and developing and testing a software-based application to help reduce the recurrence of C. diff. infection by improving follow-up and management, we believe there is a strong potential to make a real difference to address this critical public health problem.”

Sam Bozzette, MD, PhD, vice president and chief scientist of its retrospective and interventional research division, Premier Applied Sciences.  An internationally-recognized researcher and physician executive, Dr. Bozzette provides strategic clinical, analytical and operational direction to further grow the Premier Applied Sciences research business and improve the overall quality, safety and cost-effectiveness of care.  “Dr. Bozzette is a leader in medical and social sciences, and has more than 25 years of experience working with academic and non-profit healthcare providers to improve clinical decision-making practices, care delivery efficiency and effectiveness, and population health management,” said Leigh Anderson, chief information officer at Premier. “We are thrilled to have him on board to lead Premier’s data-driven research efforts to set new standards in care delivery through strategic partnerships with healthcare industry leaders across the U.S.”

Premier Applied Sciences, formerly known as Premier Research Services, combines data and analytics with objective clinical outcomes analyses, and partnerships with health systems, life sciences companies, academic institutions and professional societies to develop, teach, test and research care delivery practices and real-world interventions for healthcare improvement. It offers real-world research and analytics, retrospective research, healthcare education, clinical trial innovation and data licensing services.

The work expands Merck’s chronic disease work with Premier, which has seen them co-develop and test solutions that help promote wellness and prevention for specific groups of at-risk patients since 2016.

Raquel Tapia, associate VP, hospital/specialty marketing at Merck, said: “Combining the technical capabilities of Premier and the therapeutic area expertise of Merck has been instrumental in our ability to address these difficult healthcare challenges.

“By testing the solutions in real-world settings and learning from our growing knowledge base, we’re confident that our work together will help patients.”

The partners’ goal is to increase patient access to healthcare services, raise awareness of how to decrease patient risk of recurrence and help patients identify if they are having a recurrence.

The proposed C. diff software intervention will be tested within volunteer Premier member health systems. The firm current has an alliance of around 3,900 US hospitals and health systems and a further 150,000 or so healthcare providers and organizations.

C. diff infections cause serious and life-threatening diarrhea and have become one of the most common microbial cause of healthcare-associated infections in US hospitals. It’s thought that C. diff infections affect approximately half a million people and add $4.8 billion to US healthcare costs each year.

Abstract

Background Clostridium difficile is the most common cause of infectious diarrhea in hospitalized patients. Recurrences are common after antibiotic therapy.

Actoxumab and bezlotoxumab are human monoclonal antibodies against C. difficile toxins A and B, respectively.

Methods –  We conducted two double-blind, randomized, placebo-controlled, phase 3 trials, MODIFY I and MODIFY II, involving 2655 adults receiving oral standard-of-care antibiotics for primary or recurrent C. difficile infection. Participants received an infusion of bezlotoxumab (10 mg per kilogram of body weight), actoxumab plus bezlotoxumab (10 mg per kilogram each), or placebo; actoxumab alone (10 mg per kilogram) was given in MODIFY I but discontinued after a planned interim analysis.

The primary end point was recurrent infection (new episode after initial clinical cure) within 12 weeks after infusion in the modified intention-to-treat population.

Results In both trials, the rate of recurrent C. difficile infection was significantly lower with bezlotoxumab alone than with placebo (MODIFY I: 17% [67 of 386] vs. 28% [109 of 395]; adjusted difference, -10.1 percentage points; 95% confidence interval [CI], -15.9 to -4.3; P<0.001; MODIFY II: 16% [62 of 395] vs. 26% [97 of 378]; adjusted difference, -9.9 percentage points; 95% CI, -15.5 to -4.3; P<0.001) and was significantly lower with actoxumab plus bezlotoxumab than with placebo (MODIFY I: 16% [61 of 383] vs. 28% [109 of 395]; adjusted difference, -11.6 percentage points; 95% CI, -17.4 to -5.9; P<0.001; MODIFY II: 15% [58 of 390] vs. 26% [97 of 378]; adjusted difference, -10.7 percentage points; 95% CI, -16.4 to -5.1; P<0.001). In prespecified subgroup analyses (combined data set), rates of recurrent infection were lower in both groups that received bezlotoxumab than in the placebo group in subpopulations at high risk for recurrent infection or for an adverse outcome.

The rates of initial clinical cure were 80% with bezlotoxumab alone, 73% with actoxumab plus bezlotoxumab, and 80% with placebo; the rates of sustained cure (initial clinical cure without recurrent infection in 12 weeks) were 64%, 58%, and 54%, respectively.

The rates of adverse events were similar among these groups; the most common events were diarrhea and nausea.

Conclusions Among participants receiving antibiotic treatment for primary or recurrent
C. difficile infection, bezlotoxumab was associated with a substantially lower rate of recurrent infection than placebo and had a safety profile similar to that of placebo.

The addition of actoxumab did not improve efficacy. (Funded by Merck; MODIFY I and MODIFY II ClinicalTrials.gov numbers, NCT01241552 and NCT01513239 .).

Bezlotoxumab – A New Agent for Clostridium difficile Infection. [N Engl J Med. 2017]

U.S. Food and Drug Administration (FDA) Has Approved Merck’s (MSD) ZINPLAVA ™ (bezlotoxumab) Injection 25mg/ml To Reduce Recurrence Of Clostridium difficile Infection In Patients 18 Years Of Age Or Older

MERCKBW2015_medLogoBLK [Converted] (2)

Merck  known as MSD outside the United States and Canada, on October 22, 2016 announced that the U.S. Food and Drug Administration (FDA) has approved ZINPLAVA™ (bezlotoxumab) Injection 25 mg/mL.

Merck anticipates making ZINPLAVA available in first quarter 2017.

ZINPLAVA is indicated to reduce recurrence of Clostridium difficile infection (CDI) in patients 18 years of age or older who are receiving antibacterial drug treatment of CDI and are at high risk for CDI recurrence.

ZINPLAVA is not indicated for the treatment of CDI.

ZINPLAVA is not an antibacterial drug. ZINPLAVA should only be used in conjunction with antibacterial drug treatment of CDI.

Please see Prescribing Information for ZINPLAVA (bezlotoxumab) at http://www.merck.com/product/usa/pi_circulars/z/zinplava/zinplava_pi.pdf 

 

Patient Information for ZINPLAVA at http://www.merck.com/product/usa/pi_circulars/z/zinplava/zinplava_ppi.pdf

CDI is caused by bacteria that produce toxins, including toxin B. Symptoms of CDI include mild-to-severe diarrhea, abdominal pain and fever. The incidence of recurrent CDI is higher in certain patient populations, including people 65 years of age or older and those with compromised immune systems.

“For generations, Merck has been steadfast in its commitment to fighting infectious diseases – and that commitment continues today. ZINPLAVA is a human monoclonal antibody that binds to C. difficile toxin B and neutralizes its effects,” said Dr. Nicholas Kartsonis, vice president of clinical development, infectious diseases, Merck Research Laboratories.

Selected safety information about ZINPLAVA

Heart failure was reported more commonly in the two Phase 3 clinical trials in ZINPLAVA-treated patients compared to placebo-treated patients. These adverse reactions occurred primarily in patients with underlying congestive heart failure (CHF). In patients with a history of CHF, 12.7% (15/118) of ZINPLAVA-treated patients and 4.8% (5/104) of placebo-treated patients had the serious adverse reaction of heart failure during the 12-week study period. Additionally, in patients with a history of CHF, there were more deaths in ZINPLAVA-treated patients [19.5% (23/118)] than in placebo-treated patients [12.5% (13/104)] during the 12-week study period. The causes of death varied, and included cardiac failure, infections, and respiratory failure. In patients with a history of CHF, ZINPLAVA (bezlotoxumab) should be reserved for use when the benefit outweighs the risk.

The most common adverse reactions occurring within 4 weeks of infusion with a frequency greater than placebo and reported in ≥4% of patients treated with ZINPLAVA and Standard of Care (SoC) antibacterial drug therapy vs placebo and SoC antibacterial drug therapy included nausea (7% vs 5%), pyrexia (5% vs 3%) and headache (4% vs 3%).

Serious adverse reactions occurring within 12 weeks following infusion were reported in 29% of ZINPLAVA-treated patients and 33% of placebo-treated patients. Heart failure was reported as a serious adverse reaction in 2.3% of ZINPLAVA-treated patients and 1.0% of placebo-treated patients.

In ZINPLAVA-treated patients, 10% experienced one or more infusion specific adverse reactions compared to 8% of placebo-treated patients, on the day of or the day after, the infusion. Infusion specific adverse reactions reported in ≥0.5% of patients receiving ZINPLAVA and at a frequency greater than placebo were nausea (3%), fatigue (1%), pyrexia (1%), dizziness (1%), headache (2%), dyspnea (1%) and hypertension (1%). Of these patients, 78% experienced mild adverse reactions, and 20% of patients experienced moderate adverse reactions. These reactions resolved within 24 hours following onset.

As with all therapeutic proteins, there is a potential for immunogenicity following administration of ZINPLAVA. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to bezlotoxumab in two Phase 3 studies with the incidence of antibodies in other studies or to other products may be misleading. Following treatment with ZINPLAVA in these two studies, none of the 710 evaluable patients tested positive for treatment-emergent anti-bezlotoxumab antibodies.

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.

U.S. Panel To the Food and Drug Administration Voted 10-5 In Favor For Merck & Co. ‘s bezlotoxumab Effective At Preventing A Recurrence Of C. diff. Infection

NewsUpdate

 Merck & Co’s experimental drug to treat the most common hospital-associated infectious diarrhea
* Clostridium difficile  *  warrants approval, an advisory panel to the U.S. Food and Drug Administration said on Thursday.

 

The panel voted 10-5, with one abstention, that the drug, bezlotoxumab, was effective in preventing a recurrence of infection with Clostridium difficile, or C. difficile, a germ that causes inflammation of the colon and potentially fatal diarrhea.

The FDA is not obliged to follow the advice of its advisory panels but typically does.

The panel’s vote follows an internal review by FDA staff which found an apparent decrease in recurrence of C. difficile but expressed concern as to whether the drug could hurt the cure rate of the initial C. difficile episode.

Panelists who voted in favor of the drug acknowledged the FDA’s concerns but said they were persuaded there was a need for new targeted therapies and this one seems effective.

“We haven’t had a new drug for C. difficile in our armamentarium for some time,” Dr. Joanna Schaenman, assistant professor of medicine at UCLA David Geffen School of Medicine, said.

MORE about bezlotoxumab :   https://cdifffoundation.org/category/clinical-trials/

Merck & Co.   bezlotoxumab was successful in two Phase III trials against the recurrence of

Clostridium difficile (C. difficile) infection when combined with antibiotics.

Currently, there are no therapies approved for the prevention of recurrent disease caused by C. difficile.

Bezlotoxumab’s approval would also make it the first antibody to treat bacterial infection.

Scientists say mAbs would have benefits over small molecule antibiotics because they are less likely to drive antimicrobial resistance and are administered less frequently. “Results of these studies showed that a single, one-time infusion of the antitoxin bezlotoxumab given with standard of care C. difficile antibiotic treatment significantly reduced the recurrence of C. difficile infection compared to standard of care alone, and demonstrated this benefit over a 12-week period,” said lead investigator Mark Wilcox of the University of Leeds, UK. “These results were also demonstrated in patient subgroups known to be at high risk for C. difficile recurrence.”

C. difficile toxin B can damage the gut wall and cause inflammation, leading to the symptoms of C. difficile enteritis, which include abdominal pain and watery diarrhea. Bezlotoxumab, a fully-human monoclonal antibody, was developed by researchers at the University of Massachusetts Medical School’s MassBiologics Laboratory with Medarex (now part of Bristol-Myers Squibb), and licensed to Merck in 2009.

The studies   Merck’s studies took more than 1,000 patients each and evaluated them over 12 weeks. Participants received either a single infusion of bezlotoxumab, actoxumab (another mAb designed to fight C. difficile),a combination of the two, or a placebo. The actoxumab arm of the study ended early for efficacy and safety reasons.    Both studies had infection recurrence as their primary endpoint – this rate was significantly lower for the bezlotoxumab arms (17.4% and 15.7%) and bezlotoxumab plus actoxumab arms (15.9% and 14.9%), compared to placebos (27.6% and 25.7%). Actoxumab was found not to provide extra benefit on its own or combined with bezlotoxumab, so Merck’s marketing authorisation application is for bezlotoxumab alone.

The FDA is due to make its decision by July 23.

SANOFI_Pasteur_RVB

Sanofi Pasteur, one of the leading vaccine manufacturers in the world, is in the midst of its Phase III clinical trial called Cdiffense to study its investigational vaccine to prevent Clostridium difficile infection (CDI). The trial is now in more than 20 countries across 5 continents to evaluate the safety, immunogenicity and efficacy of an investigational vaccine for the prevention of primary, symptomatic CDI. The investigational C. diff vaccine is designed to produce an immune response that targets the toxins generated by C. diff bacteria, which can cause inflammation of the gut. The investigative vaccine ultimately may help prevent a future infection from occurring. Volunteers for the study should be age 50 or older and planning an upcoming hospitalization or have had at least two hospital stays and have received systemic antibiotics in the past year.

DAV-Logo (2)

Da Volterra is a biopharmaceutical company, privately-held and headquartered in Paris (France), focused on the discovery and development of innovative therapeutic and preventive products for Clostridium difficile and multi-resistant infections. Our most advanced product, DAV132, is designed as a prophylactic treatment intended to prevent the development of
C. difficile infection, by binding with and neutralizing common antibiotics in the gut
.
DAV132 decreases the risk of triggering CDI by inactivating residual antibiotics in the colon
before they can disrupt the bacterial flora, without impacting the systemic efficacy of the antibiotics.

It is noteworthy that DAV132 is developed to accompany all oral and intravenous antibiotics of any class and would therefore significantly reduce the risks to acquire C.difficile infections for patients at risk (especially patients who had prior episodes). We see DAV132 as a real game changer for C.difficile prevention.

Have a look at our video presenting the mechanism of action of DAV132:

http://davolterra.com/content/dav132-preventing-occurence-and-recurrence-clostridium-difficile-infections-video

The video is highly illustrative of what C.diff is and how C.diff is triggered.

We have already performed 2 clinical trials with DAV132 and we have a very exciting dataset (both preclinical and clinical) suggesting that DAV132 will very effectively prevent C.diff infections. I would be happy to exchange with you more information on this. Our next clinical trial, in patients actually treated with antibiotics and at-risk of C.diff, will start in Q4 2015 or early 2016.

The biology of the microbiome is driven by ecologies—the functional collections of various organisms—which are central to health and disease. Seres is developing Ecobiotic® therapeutics to treat diseases where an abnormal (unhealthy) microbiome is a significant factor in the underlying cause of the disease. Our first clinical program, The ECOSPOR Research study is in the treatment of recurrent
Clostridium difficile infection.
About The ECOSPOR Research Study  Although antibiotics are used to treat recurrent
C. difficile infection, most of the time they do not cure C. difficile. In addition, antibiotics continue to wipe out the good bacteria that protect you
against C. difficile. Currently, there are no medications available that can prevent this infection from coming back when your gut is defenseless.

SER-109 is an investigational medicine being developed to prevent recurrent C. difficile from coming back again. The idea is to first treat patients with antibiotics that work against C. difficile so that the diarrhea goes away. Then patients may get SER-109 to keep the C. difficile infection from coming back.

In the ECOSPOR study, doctors will compare SER-109 to a placebo pill, which looks like SER-109. However, the placebo pill will have no medication inside it. Patients will be randomly assigned to receive either SER-109 or placebo. The study is designed to provide more information about the potential safety and effectiveness of SER-109, and will last about 7 months. The results will help doctors and researchers learn whether SER-109 could one day be used to prevent recurrent CDI.

Who Is Eligible For The ECOSPOR Study?
To pre-qualify for this study, a person must:
• Be 18 years of age or older
• Have a history of at least 3 episodes of Clostridium difficile Infection (CDI) in the last 9 months, including the current episode
• Not have active irritable bowel syndrome with diarrhea within the previous 24 months
All study-related visits, tests, and medication will be provided to the study patients at no cost. In addition, reimbursement for time and travel may be provided.

How to Enroll in the study?   The ECOSPOR Study is now open for enrollment. It is posted on ClinicalTrials.gov.All the sites which are enrolling patients are listed on clinicaltrials.gov, including contact information for the sites. If a doctor in the study thinks you may be a good candidate, you will be given complete information about the study including everything you should know before you join.  You can also contact clinicalstudies@sereshealth.com to find a doctor near you who is involved in the study.

summit

Summit Therapeutics  has reported ‘outstanding’ results in the phase II trial of ridinilazole, its new C.difficile infection (CDI) treatment.

During the trial, the new oral antibiotic significantly outperformed vancomycin, the current standard prescription, which was the primary objective said Summit.

Over two-thirds (66.7%) of those treated showed a sustained clinical response (SCR) against 42.4% for vancomycin.

The statistical superiority was driven by a large numerical reduction in recurrent disease compared with vancomycin, which Summit said was key as recurrence is one of the hardest things to stop.

C.difficile or CDI is a growing danger for patients in hospital, care homes and the wider community.

Annually, there are between 450,000 and 700,000 cases in the US alone, with the elderly and sick especially vulnerable.

One study has suggested it costs US $4.8bn to treat these people.

“The healthcare community is acutely aware of the major threat CDI poses, particularly given widespread antibiotic use and our aging population,” said Glyn Edwards, Summit’s chief executive.

The biggest unmet need in CDI treatment is reduce recurring cases, he added and the results from the latest trial had exceeded its ‘wildest expectations’.

“These outstanding clinical data from CoDIFy strongly support the profile of ridinilazole as a narrow spectrum antibiotic.

“There is a vital need for potent new antibiotics, and the potential of ridinilazole has attracted great interest.

Edwards added that the results from the CoDIFy trial were exceptionally encouraging and the aim no is to advance ridinilazole into Phase 3 clinical trials.

Here, the company would evaluate partnership opportunities against the benefit of it forward itself, he added.

Professor Mark Wilcox, at Leeds University and Public Health England’s lead consultant on C.difficile added that the latest data indicated ridinilazole could become an important new treatment option for CDI with the potential to reduce the high rates of recurrent disease that remain a key clinical challenge.

CoDIFy was a double blind, randomised, active controlled, multicentre, Phase II clinical trial that evaluated the efficacy of ridinilazole against vancomycin in 100 patients in the US and Canada.

Results from a second CoFIFy trail are due next year, though Edwards said the results announced today would provide the bulk of the quantitative data.

ridinilazole has already received Qualified Infectious Disease Product, or QIDP, designation and has been granted Fast Track status from the US Food and Drug Administration

rebiotixlogo

Rebiotix Inc. is a clinical stage biotechnology company founded to revolutionize the treatment of debilitating diseases by harnessing the power of the human microbiome. Microbiota Restoration Therapy (MRT) is the company’s platform for delivering live microbes into a sick patient’s intestinal tract to treat disease.

Clinical Program
PUNCH™ CD is the name of Rebiotix’s clinical program to assess the safety and efficacy of RBX2660 for the treatment of recurrent Clostridium difficile (C. diff.) infection. It is the most advanced human clinical program evaluating a microbiota-based drug conducted in coordination with the U.S. Food and Drug Administration (FDA) with the goal of developing and commercializing a new therapy to treat patients with recurrent episodes of C. diff. infection. Rebiotix has completed enrollment its PUNCH CD 2 study and continues to assess the safety and efficacy of RBX2660.

PUNCH™ CD 2
Rebiotix has completed enrollment in its PUNCH CD 2 study, a Phase 2B multi-center, randomized, double-blind, placebo-controlled trial to evaluate RBX2660 for the treatment of recurrent C. diff. infection. A total of 117 patients recruited at more than 20 sites in the U.S. and Canada were enrolled in the study, which is the largest randomized controlled study of a MRT for recurrent C. diff. to date.

In this study, the patients received either the microbiota-based drug or a placebo via enema. Neither the doctor nor the patients knew what treatment was received in order to get an unbiased measurement of the drug’s true effectiveness. If a patient’s C. diff. infection symptoms returned, even if they were in the placebo arm of the study, they may have been eligible to receive RBX2660. This is referred to as the open-label portion of the study.

PUNCH™ CD
The PUNCH CD study, which was a Phase 2 open label safety and preliminary efficacy study of RBX2660, was successfully completed in July 2014. An open label study means everyone enrolled in the study got the treatment and it is generally the first phase of a new product development program. The study demonstrated a success rate of 87% for those treated with no serious adverse events related to either the product or the method of delivery.

Product Pipeline
Rebiotix is currently exploring the feasibility of an oral formulation, RBX7455, for the prevention of C. diff.

In addition, Rebiotix is leveraging their years of knowledge and experience to develop MRT applications for other conditions that result from disruption of the gut microbiota.

Merck & Co. will file the first antibacterial monoclonal antibody by the end of 2015, the company says.

bezlotoxumab was successful in two Phase III trials against the recurrence of

Clostridium difficile (C. difficile) infection when combined with antibiotics.

Merck plans to file new drug applications for the monoclonal antibody in the US, Canada and EU by the end of the year. Currently, there are no therapies approved for the prevention of recurrent disease caused by C. difficile.

Bezlotoxumab’s approval would also make it the first antibody to treat bacterial infection.

Scientists say mAbs would have benefits over small molecule antibiotics because they are less likely to drive antimicrobial resistance and are administered less frequently. “Results of these studies showed that a single, one-time infusion of the antitoxin bezlotoxumab given with standard of care C. difficile antibiotic treatment significantly reduced the recurrence of C. difficile infection compared to standard of care alone, and demonstrated this benefit over a 12-week period,” said lead investigator Mark Wilcox of the University of Leeds, UK. “These results were also demonstrated in patient subgroups known to be at high risk for C. difficile recurrence.”

C. difficile toxin B can damage the gut wall and cause inflammation, leading to the symptoms of C. difficile enteritis, which include abdominal pain and watery diarrhea. Bezlotoxumab, a fully-human monoclonal antibody, was developed by researchers at the University of Massachusetts Medical School’s MassBiologics Laboratory with Medarex (now part of Bristol-Myers Squibb), and licensed to Merck in 2009.

The studies   Merck’s studies took more than 1,000 patients each and evaluated them over 12 weeks. Participants received either a single infusion of bezlotoxumab, actoxumab (another mAb designed to fight C. difficile),a combination of the two, or a placebo. The actoxumab arm of the study ended early for efficacy and safety reasons.    Both studies had infection recurrence as their primary endpoint – this rate was significantly lower for the bezlotoxumab arms (17.4% and 15.7%) and bezlotoxumab plus actoxumab arms (15.9% and 14.9%), compared to placebos (27.6% and 25.7%). Actoxumab was found not to provide extra benefit on its own or combined with bezlotoxumab, so Merck’s marketing authorisation application is for bezlotoxumab alone.

XBiotech is a biotech company located in Austin, Texas and was founded on the concept of the “True Human Antibody”.  Antibodies are specialized proteins, which are produced by the immune system.  Their function is to bind to a very specific target, such as a virus or bacteria, and aid in the elimination of these targets by the immune system.  Monoclonal antibodies were developed as a class of drug, which use the specific targeting function of the antibody to target substances that cause disease. Currently approved monoclonal antibodies however, are developed in the laboratory or in mice.  XBiotech’s approach is to isolate antibodies that are present naturally in healthy human donors, and develop these into products that can be used to treat disease.  We believe that antibodies isolated from humans, will be safer and will function better than so called antibodies marketed as “fully human”, which are in fact engineered.

Over the past decade, Clostridium difficile (C. diff) has emerged as a significant public health threat.  In fact, the CDC has designated it as an “Urgent threat level.”

In October 2015, XBiotech announced it had set out to develop a first-in-class oral monoclonal antibody against C. diff infection. Just two weeks after this announcement, the Company reported it had already identified positive blood samples for anti-clostridium difficile antibodies after screening blood donations from healthy volunteers.

XBiotech’s plans to develop an antibody therapy that directly targets and neutralizes the bacteria. The Company intends to deliver the therapy orally, targeting C. diff in the gastrointestinal tract, where the antibody could reduce the bacteria’s ability to establish debilitating or life threatening infections.
