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.

Synthetic Biologics’ SYN-004 Phase 2b Proof-of-Concept Clinical Trial

 A global, multi-center, randomized, double-blind, placebo-controlled clinical trial to evaluate the ability of SYN-004 to degrade certain IV beta-lactam antibiotics within the GI tract to maintain the natural balance of the gut microbiome for the prevention of C. difficile infection, C. difficile associated diarrhea and antibiotic-associated diarrhea in patients hospitalized for a lower respiratory tract infection and receiving IV ceftriaxone.

Update July 2016:

the United States Adopted Names Council (USAN) of the American Medical Association has approved the use of “ribaxamase” (Rye-bak’-sa-mase) for Synthetic Biologics’ SYN-004. Ribaxamase is the Company’s Phase 2 development candidate designed to protect the gut microbiome from the unintended effects of certain commonly used intravenous (IV) beta-lactam antibiotics for the prevention of C. difficile infection (CDI), antibiotic-associated diarrhea (AAD) and the emergence of antibiotic-resistant organisms.

Synthetic Biologics recently reported positive results from two Phase 2a clinical trials demonstrating a correlation of the 150 mg dose of ribaxamase with the degradation of residual IV ceftriaxone alone, and in the presence of the proton pump inhibitor (PPI), esomeprazole, to levels that were near or below detectable in the intestinal chyme of healthy participants with functioning ileostomies. A Phase 2b proof-of-concept, randomized, placebo-controlled clinical trial is currently underway to evaluate the ability of ribaxamase to prevent CDI and AAD in patients hospitalized with a lower respiratory tract infection and receiving IV ceftriaxone. An interim analysis of blinded data performed by an independent data monitoring committee is expected in summer of 2016.

“The approval of the generic name ribaxamase for SYN-004 by USAN is a defining milestone for Synthetic Biologics. Ribaxamase represents a newly created and innovative first-in-class drug designed to protect the naturally occurring gut microbiome from the unintended consequences of antibiotic use,” said Jeffrey Riley, President and Chief Executive Officer. “By degrading certain IV beta-lactam antibiotics before they reach the gastrointestinal (GI) tract, ribaxamase may not only prevent the onset of CDI and AAD, but has the potential to be an instrumental tool for preventing the emergence of antibiotic resistance in organisms which comprise the gut microbiome. We are excited for the continued clinical development of ribaxamase and look forward to sharing our progress including announcing results from our ongoing global Phase 2b proof-of-concept clinical trial.”

Seres Therapeutics

Seres Therapeutics is developing Ecobiotic® drugs designed to prevent C diff infections from coming back again.

Most C diff infections occur after antibiotic treatment. Why? Our gut contains trillions of microbes, called the microbiome, which protects us from bacterial invaders that can cause disease. Antibiotics kill both good and bad bacteria, leaving holes in this ecology (community) of microbes. When the microbiome is damaged, bad bacteria, like C diff, can take advantage and cause disease. Although specific antibiotics can kill the active C diff bacteria, the sleeping forms (ie, spores) are untouched. These spores turn into active C diff bacteria and cause disease again and again – usually after antibiotic treatment has finished.

Seres Therapeutics has developed an oral medicine called SER-109, which aims to prevent C diff from coming back by repairing the microbiome. This Ecobiotic® drug is being studied in a large Phase 3 clinical trial that is enrolling patients who have had multiple C diff infections. This important clinical study is being done in the United States and Canada and may provide the final clinical data needed to support FDA and Canadian drug approvals. For more information, please follow this link to the patient website:  https://serescdiffstudy.com/

Seres Therapeutics is also enrolling patients into a phase 1b trial of SER-262, which is an Ecobiotic® drug to prevent recurrence among those experiencing their first C diff infection.

For more information visit the website:  www.serestherapeutics.com and click on the tab “Clinical Trials” tab located at the top of the page and scroll down to SER-262 to learn more about this study.

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.

Valneva Announces Start of Phase II Clinical Trial of its Clostridium difficile vaccine candidate

UPDATE: Valneva SE July 26, 2016 announced the successful completion of its Phase II study for its prophylactic vaccine candidate VLA84 targeting primary prevention of C. difficile infection (CDI), which is emerging as a leading cause of life-threatening, healthcare-associated infections (HAIs) worldwide.  Valneva previously announced positive top-line data from the Phase II study at the end of 2015. These initial results, which included data up to Day 56 following initial vaccination, were presented at the American Society of Microbiology’s annual meeting, ASM Microbe 2016, on June 17 in Boston. VLA84 was immunogenic at all doses and formulations tested, in that Immunoglobulin G (IgG) and functional (neutralizing) antibody responses were observed. The study met its primary endpoint in terms of identifying the dose/formulation with the highest seroconversion rate against both toxins A and B and confirmed the favorable safety profile observed in Phase I.

Final Phase II results included the follow-up of study participants until Day 210. This long-term data confirmed the optimal vaccine dose and formulation that had been previously identified (high-dose formulation without adjuvant) with an immunogenicity profile at Day 210 in line with expectations. Long-term safety concerns were not seen in any of the different vaccine doses tested.

……..

  • First Study participant(s) enrolled in Phase II trial which aims to enable Phase III entry upon successful completion
  • Study to enroll 500 healthy subjects aged 50 years and older in the United States and Germany
  • First results are expected in Q4 2015

   Lyon (France), December 18, 2014European biotechnology company Valneva SE (“Valneva”) announced today the initiation of the Phase II clinical trial of its VLA84 prophylactic vaccine candidate against Clostridium difficile (C. difficile), the main cause of nosocomial diarrhea. Data from the Phase I study in healthy elderly and adults showed good safety and immunogenicity of the vaccine candidate, and indicated functionality of induced antibodies, supporting the Company`s decision to progress the vaccine
candidate into Phase II

C. diff. Infection (CDI) Treatments On the Horizon

 

 

summit

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

To LISTEN to the July 2016 Live Broadcast from the C. diff. Spores and More Global Broadcasting Network program with Dr. Richard Vickers, and Dr. Dr Kevin W Garey, PharmD, Click on the Summit Therapeutics Logo above : Ridinilazole, A Microbiome Preserving Antibiotic For The Treatment Of a C. difficile Infection

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

rebiotixlogoListen to Lee Jones, President, CEO of Rebiotix discuss the clinical program and RBX2660, Click on the Rebiotix logo on the left and enjoy listening to the May  2016 podcast from a live broadcast on “C. diff. Spores and More Global Broadcasting Network.”

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.

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.
