Sanofi Pasteur Ends Development of C. difficile Vaccine

Sanofi Pasteur SA  Pharmaceutical company announced on Friday, December 1, 2017  that it had ended development of an experimental vaccine for Clostridium difficile infection, after an early look at late-stage trial results indicated a low probability for success.

About three million Americans are infected annually with the bacterium – also known as C. diff – ———

The move marks the second blow in a week to Sanofi’s vaccine program after the Paris-based company on Wednesday said use of its new dengue vaccine will be strictly limited due to evidence it can worsen the disease in people who have not previously been exposed to the mosquito-borne virus.

Sanofi’s Dengvaxia vaccine is the world’s first approved shot for preventing dengue infection, which kills about 20,000 people a year and infects hundreds of millions.

The company said in a statement that all data from vaccinated volunteers in the C. diff trial will continue to be analyzed for more information and shared with the scientific community.

As many as 30,000 Americans die each year from the bacterium, usually after recurrences of infection. The infections are typically the result of taking antibiotics, which wipe out friendly bacteria in the colon that normally keep C. diff under control.

Sanofi said it will continue to focus on six other vaccine projects in development.

Clinical Studies In Progress To

Help You — Help Them — Help Others  ♥

 

 

Here is a list of Clinical Trial Phases:

Clinical trials are conducted in a series of steps, called phases – each phase is designed to answer a separate research question.

  • Phase I: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
  • Phase II: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
  • Phase III: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
  • Phase IV: Studies are done after the drug or treatment has been marketed to gather information on the drug’s effect in various populations and any side effects associated with long-term use.

Pfizer Announces Positive Top-Line Results from Phase 2 Study of Investigational
Clostridium difficile Vaccine for the
Prevention of C. difficile Infection

Pfizer’s C. difficile Vaccine Candidate to Commence Phase 3 Study in First Half of 2017

C. difficile is an Increasing Worldwide Concern Associated with Approximately 29,000 Annual Deaths in the U.S. Alone
On Thursday, January 26, 2017 Pfizer Inc. announced that the Phase 2 study
evaluating the Company’s Clostridium difficile (C. difficile) vaccine
candidate, PF-06425090, provided positive data, based on a pre-planned interim analysis.

The randomized Phase 2 study (NCT02561195) examined the safety, tolerability, and immunogenicity of the vaccine in healthy adults 65 to 85 years of age. Pfizer’s vaccine candidate is designed to help prevent C. difficile infection (CDI), which can include life-threatening diarrhea and pseudomembranous colitis,1 by inducing a functional antibody response capable of neutralizing the two main disease-causing toxins produced by
C. difficile (toxins A and B).2

“Despite improved infection control measures, C. difficile disease continues to rise, further augmenting an already urgent public health threat with particular negative impact on older adults,” said Kathrin Jansen, Ph.D., senior vice president and head of Vaccine Research and Development for Pfizer Inc. “We are very encouraged by these interim immunogenicity and safety results demonstrating robust increases in vaccine-elicited neutralizing antibodies to both toxins, that we believe could provide protection against C. difficile disease.”

Based on findings from the pre-planned interim analysis, Pfizer’s C. difficile vaccine candidate will progress into Phase 3 in the first half of 2017.

Pfizer’s C. difficile vaccine candidate was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) in August 2014. The FDA’s Fast Track designation is designed to facilitate the development and expedite the review of new drugs and vaccines intended to treat or prevent serious conditions and address an unmet medical need.3 About the Phase 2 Study The Phase 2 study (NCT02561195) was a randomized, placebo-controlled, observer-blinded study of more than 850 healthy adults 65-85 years of age, evaluating the safety, tolerability, and immunogenicity of two dose levels (100 µg and 200 µg) of Pfizer’s C. difficile vaccine candidate on two different three-dose vaccination schedules (Days 1/8/30 and Months 0/1/6). More information about the PF-06425090 Phase 2 study can be found at www.clinicaltrials.gov (link is external).

About Clostridium difficile

Clostridium difficile (C. difficile) is a spore-forming pathogen that typically causes symptoms in individuals with altered gut microbial flora, releasing toxins that can result in a range of disease manifestations from asymptomatic colonization to diarrhea, pseudomembranous colitis, toxic megacolon, intestinal perforation, or, in the most severe cases, death.4,5 C. difficile, classified by the U.S. Centers for Disease Control and Prevention (CDC) as an urgent public health threat in 2013,6 is the most common cause of antibiotic-associated diarrhea in the healthcare setting and an increasing concern worldwide.7 Responsible for approximately 453,000 U.S. cases (associated with 29,000 deaths) in 2011,8 CDI disproportionately affects older adults, with nearly two-thirds of cases in patients over the age of 65.9 Current treatment options may offer temporary therapeutic improvements, but will not provide long-term protection.10 Up to 25% of patients treated for a first episode of CDI experience a first recurrence of infection, and up to 65% of those patients who experience a first recurrence will experience multiple recurrences.1,11

Merck Nearing FDA Approval For Its Antitoxin (bezlotoxumab) For Prevention Of C. difficile Infection (CDI) Recurrence

Merck  is nearing FDA approval for its Clostridium difficile-fighting antibody, picking up the agency’s priority review designation with the promise of a shortened vetting process.

The FDA accepted Merck’s application for bezlotoxumab and promised to hand down a final decision by July 23, shortening the standard 10-month review to 6 months.

The treatment, licensed from Medarex in 2009, is an antibody designed to block C. difficile toxin B, which damages the gut wall and leads to inflammation that trigger abdominal pain and diarrhea. In Phase III, adding bezlotoxumab to standard of care significantly reduced C. difficile recurrence in high-risk patients after 12 weeks, Merck disclosed in September.

Bezlotoxumab is among the most advanced assets in Merck’s infectious disease pipeline, bolstered by the company’s $9.5 billion buyout of antibiotics specialist Cubist Pharmaceuticals last year. Merck is also at work on therapies for pneumonia, bacterial infection and HIV as it awaits approval for a combination treatment targeting hepatitis C.

 

FULL STATEMENT FROM MERCK:

Merck  known as MSD outside the United States and Canada  January 28, 2016  (today) announced that the U.S. Food and Drug Administration (FDA) has accepted for review the Biologics License Application (BLA) for bezlotoxumab, an investigational antitoxin for prevention of Clostridium difficile (C. difficile) infection recurrence.

The FDA granted Priority Review for bezlotoxumab, with a Prescription Drug User Fee Act (PDUFA) action date of July 23, 2016.

The company also has filed a marketing authorization application for bezlotoxumab with the European Medicines Agency (EMA) that is currently under review.

“Recurrence is a major challenge with C. difficile infection, one of the most common healthcare-associated infections in U.S. hospitals,” said Dr. Roy Baynes, senior vice president of clinical development, Merck Research Laboratories. “Currently, there are no therapies approved for the prevention of C. difficile infection recurrence. As part of Merck’s commitment to the fight against infectious diseases, we look forward to continuing to work with the FDA and EMA to bring forward this novel medicine for appropriate patients.”

The application for bezlotoxumab is based in part on data from the pivota lMODIFY I and MODIFY II clinical trials. Data from these trials were previously presented at the Interscience Conference of Antimicrobial Agents and Chemotherapy (ICAAC) and International Congress of Chemotherapy and Infection (ICC) 2015 joint meeting.

About bezlotoxumab

Bezlotoxumab is an investigational antitoxin given in conjunction with standard of care antibiotics that are used in the treatment of C. difficile infection. It is not an antibiotic. Bezlotoxumab is designed to neutralize C. difficile toxin B, a toxin that can damage the gut wall and cause inflammation, leading to C. difficile-associated diarrhea.
