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

Synthetic Biologics is developing cutting-edge therapeutics to treat pathogen-specific diseases.

Our two leading candidates are:
SYN-004 (ribaxamase) to prevent C. difficile infection and antibiotic-associated diarrhea
SYN-010 to treat irritable bowel syndrome with constipation (IBS-C)

 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.”

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

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

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

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.”

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

seres-therapeutics-inc-logo

 

 

Seres Therapeutics,  is creating a new class of medicines to treat diseases resulting from functional deficiencies in the microbiome, a condition known as dysbiosis. New insights into the human microbiome are fundamentally reshaping how we understand and treat a wide range of diseases, creating new possibilities for patients not served by current therapeutic approaches. Ecobiotics are ecological compositions of beneficial organisms that are designed to reestablish a healthy microbiome. The discovery efforts at Seres Therapeutics currently span metabolic, inflammatory, and infectious diseases.

MARCH 2017 NEWS:  Seres Therapeutics Inc. a leading microbiome therapeutics platform company, announced on March 16th, 2017 plans to initiate a new SER-109 Phase 2 clinical study (ECOSPOR III) in patients with multiply recurrent Clostridium difficile (C. difficile) infection. The ECOSPOR III study design was finalized following a positive Type B meeting with the U.S. Food and Drug Administration (FDA). In a separate announcement today, Seres reported fourth quarter and full year 2016 financial results and provided an update on multiple ongoing microbiome clinical programs.

Seres plans to initiate a new SER-109 clinical study in approximately 320 patients with multiply recurrent C. difficile infection. Study participants will be randomized 1:1 between SER-109 and placebo. To ensure accurate measurement of C. difficile infection, diagnosis of recurrent C. difficile infection for both study entry and for endpoint analysis will be confirmed by C. difficile cytotoxin assay. Patients in the SER-109 arm will receive a total SER-109 dose, administered over three days, approximately 10-fold higher than the dose used in the prior ECOSPOR study. ECOSPOR III will evaluate patients for 24 weeks and the primary endpoint will compare the C. difficile recurrence rate in subjects who receive SER-109 verses placebo at up to eight weeks after dosing. The FDA has agreed that this new trial may qualify as a pivotal study with achievement of a persuasive clinical effect and addressing FDA requirements, including clinical and statistical factors, an adequately sized safety database, and certain CMC parameters.

“We are pleased to have received highly constructive guidance from the FDA regarding further SER-109 clinical development and we plan to initiate a new clinical study as soon as possible,” said Roger J. Pomerantz, M.D., President, CEO and Chairman of Seres. “Our prior SER-109 studies provided important new biological and clinical data that have advanced our pioneering microbiome therapeutic efforts. Based on our learnings and dialogue with the FDA, we believe that we are now positioned to initiate a robust clinical study that may provide the basis for SER-109 approval. There is an urgent need for improved treatments for C. difficile infection, and we believe SER-109 has great potential to address the underlying cause of the disease and become the first approved microbiome therapeutic in this new field of medicine.”

Seres Therapeutics Inc.  a leading microbiome therapeutics company, announced  that it has initiated a Phase 1b clinical trial evaluating SER-262 in patients with primary Clostridium difficile infection (CDI).

SER-262 is an Ecobiotic® rationally-designed, fermented microbiome therapeutic derived by a manufacturing process that does not require human donor material. SER-262 is the first synthetically-derived and designed microbiome therapeutic ever to reach clinical-stage development.

SER-262, an oral capsule, contains a consortium of twelve bacterial strains in spore form. The strains included in SER-262 were selected based on multiple criteria including analysis of human microbiome data, efficacy in animal models of CDI, and bacterial strain level characterization.1 The composition of SER-262 was selected among Seres’ field-leading human microbiome library containing over 14,000 well-characterized strains of bacteria.

The SER-262 Phase 1b study, a 24-week randomized, placebo-controlled, dose escalation study is expected to enroll approximately 60 patients who have experienced a first episode of CDI. The primary endpoint of the study will compare the CDI recurrence rate between the SER-262 and placebo groups at up to 8 weeks after dosing.

Approximately 640,000 and 820,000 individuals in U.S. each year experience a primary occurrence of CDI,and about 25 percent will suffer from a subsequent recurrence.

“Advancing SER-262 to the clinic is a landmark event for Seres and the microbiome field in general. The SER-262 program has demonstrated our ability to rapidly develop a new class of synthetic microbiome therapeutics comprised of rationally designed bacterial compositions,” said Roger Pomerantz, M.D., President, Chief Executive Officer and Chairman of Seres. “We intend to continue to utilize our platform technology and unique knowledge of bioinformatics, microbiology, manufacturing and regulatory requirements to develop additional rationally designed microbiome therapeutics for serious diseases in each of our three therapeutic franchises: infectious disease, immunology and metabolic disease.

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

Reported January 2017:  With input from the FDA and EMA, Summit intends to design the Phase 3 clinical programme to evaluate superiority of ridinilazole over standard of care in the treatment of C. diffiicle Infection (CDI).

A positive Phase 3 result on superiority has the potential to support the commercial launch of ridinilazole as a differentiated therapy that can both treat initial CDI and reduce disease recurrence.

Mr Glyn Edwards, Chief Executive Officer of Summit commented: “The constructive end of Phase 2 meetings with the US and European regulators have enabled us to design a Phase 3 programme that focuses on evaluating ridinilazole’s superiority over standard of care.

This is something we believe would help differentiate our novel class antibiotic from currently marketed CDI treatments and those in late-stage development. Superiority in the combined measure of treatment of initial infection and importantly, reduction in recurrence, could position ridinilazole for front-line treatment of CDI.”

Summit discussed its Phase 3 development programme with the FDA at an End of Phase 2 meeting and through a scientific advice process with EMA. With input from both agencies, the Phase 3 programme is expected to include two trials evaluating ridinilazole as compared to the standard of care, vancomycin, each of which would enrol approximately 700 patients with CDI with the primary endpoint being superiority in sustained clinical response (‘SCR’). Other planned endpoints will include health economic outcome measures. The Phase 3 trial designs are consistent with the successful proof of concept Phase 2 trial, CoDIFy, in which ridinilazole achieved statistical superiority over vancomycin in SCR. SCR is a combined endpoint that measures cure at the end of treatment and a lack of recurrence in the 30 days after treatment. FDA also confirmed that ridinilazole would be eligible for Priority Review based on its QIDP designation.

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.

January 2017

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.”

Additional 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.

Currently, clinical trials are ongoing to assess the efficacy and safety of DIFICID, in either a tablet and oral suspension formulation, in pediatric patients with CDAD.  **  In addition, DIFICID is currently in clinical trials to determine the efficacy of use as a prophylaxis against CDAD in adult patients undergoing hematopoietic stem cell transplantation (HSCT).

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.
