Crestovo Doses Recurrent C. diff. Infection Patients In PRISM 3 – A Phase 2 Clinical Trial Testing CP-101 Microbiota

Crestovo doses recurrent Clostridium difficile infection (C. difficile) patients in PRISM 3, a phase 2 clinical trial testing CP101 (Microbiota).

The company is developing a Full-Spectrum Microbiota that harnesses the human gut microbiome. CP101, a first-in-class, lead microbiome therapy, is an encapsulated, single dose, orally-administered medicine that contains the full complement of functional microorganisms that may help restore the dysbiotic microbiota to a normal, functioning gut microbial community.

As Published in MD Mag :  http://www.mdmag.com/medical-news/phase-2-clinical-trial-tests-cp101-in-subjects-with-recurrent-c-diff

“CP101 has the potential to be the first therapy seeking FDA-approval utilizing the human gut microbiome,” Joseph Lobacki, chief operating officer, interim chief executive officer, Crestovo, said.

PRISM 3 is a multicenter, randomized, placebo-controlled trial evaluating the efficacy and safety of Microbiota in approximately 240 patients with recurrent C. difficile at clinical sites throughout the US.

Primary outcomes include a proportion of patients with no recurrence of symptomatic, laboratory confirmed C. difficile infection through 8 weeks, following administration of Microbiota, compared to the placebo, as well as a proportion of participants with adverse effects assessed by CTCAE v4.0 through 8 weeks mapped to system organ class.

Secondary outcome measures include a proportion of subjects sustaining clinical cure by a C. difficile subtype; through week 8, time to first recurrent C. difficile during the study at week 8 and 24; and a proportion of patients with no recurrence of symptomatic, laboratory confirmed infection at week 24.

Study arms include high dose full spectrum Microbiota, low dose full spectrum Microbiota and a placebo.

Inclusion criteria includes the ability to provide written informed consent, men or women 18–85 years age, a current diagnosis of a recurrence of non-severe, non-complicated C. difficile, and a clinical response to a standard course of oral vancomycin therapy to treat the current episode of recurrent C. difficile.

Top-line data from PRISM 3 is expected to release in December 2018.

Raising C. difficile awareness is essential to build upon and advance existing knowledge and necessary for overcoming the challenges our healthcare communities are faced with today.

“None of us can do this alone — All of us can do this together”

Nearly half a million Americans suffered from Clostridium difficile (C. diff.) infections in a single year according to a study released February 25, 2015 by the Centers for Disease Control and Prevention (CDC).   C. diff. is a leading cause of infectious disease death worldwide; 29,000 died within 30 days of the initial diagnosis in the USA.   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.

European Patent Office Has Granted European Patent Which Provides Composition Of Matter Coverage For Synthetic Biologics’ ribaxamase

SyntheticBiologics2016LOGO

Synthetic Biologics; a clinical stage company focused on developing therapeutics to protect the gut microbiome announced on July 12, 2016  that the European Patent Office has granted European Patent No. 2576776 which provides composition of matter coverage for ribaxamase, the Company’s Phase 2 drug candidate designed to degrade certain IV beta-lactam antibiotics within the GI tract and maintain the natural balance of the gut microbiome for the prevention of Clostridium difficile infection (CDI), antibiotic-associated diarrhea (AAD) and the emergence of antibiotic-resistant organisms.

This is Synthetic Biologics’ first patent directly pertaining to ribaxamase in Europe and adds to the Company’s established and extensive patent estate.

In addition, the U.S. Patent and Trademark Office (USPTO) has granted
US Patent No. 9,376,673, and issued a Notice of Allowance for another application (US 15/160,669), with composition of matter claims for various beta-lactamase candidates related to ribaxamase. These new patent assets further strengthen the Company’s coverage of its novel proprietary candidate, ribaxamase, which is also covered by a previously granted composition of matter patent in the U.S.

“The successful granting of this composition of matter patent in Europe, alongside our continued patent successes in the U.S., further strengthens Synthetic Biologics’ role as a leader in the development of microbiome-focused programs intended to address largely unmet medical needs,” said Jeffrey Riley, President and Chief Executive Officer. “As we continue to enjoy momentum in the clinic, our progress is further complimented by our well established and reinforced patent estate for ribaxamase.”

Ribaxamase is designed to degrade certain intravenous (IV) beta-lactam antibiotics excreted into the gastrointestinal (GI) tract to maintain the natural balance of the
gut microbiome.

C. difficile is associated with approximately 453,000 CDIs and > 29,000 C. difficile-related deaths in the United States each year[i].

Upon issuance, these newly allowed applications reinforce Synthetic Biologics’ extensive C. difficile-related patent estate, which includes approximately 40 U.S. and foreign patents and approximately 30 U.S. and foreign patent pending applications, and patents and patent applications with terms that extend from at least 2031 to 2036.

Microbiome – C. diff. Treatments On The Horizon

NewsUpdate

 

 

 

PROBIOTICS:

Pick a disease or disorder, and somebody, somewhere, has said that a probiotic supplement—an over-the-counter, unregulated pill usually filled with a single strain of friendly gut bacteria—might cure it, whether it’s cancer, obsessive-compulsive disorder, or a yeast infection.

But there’s very little evidence that probiotic supplements do any good. “There’s a lot of promise here but not a lot of proof yet,” said Cliff McDonald, associate director for science at the Centers for Disease Control and Prevention’s Division of Healthcare Quality Promotion.

 #####

CDC Reports:

Half a million people a year are infected with C. diff in the U.S., the CDC estimates, with 29,000 annual deaths related to the diarrheic bacterium. More than 65 percent of C. diff infections involve exposure in a health-care facility, according to a 2015 study, creating more than $4.8 billion in excess health-care costs at acute-care facilities alone.

C. diff. Treatments On The Horizon:

Seres Therapeutics, a microbiome-based biopharmaceutical company in Cambridge, Mass., is developing a pill, subject to a rigorous approval process under the Food and Drug Administration, to tackle recurrent Clostridium difficile. (The digestive system’s microbiome is the community of healthy gut bacteria that normally reside in the body.)

Seres aims to put the science behind a proven treatment of recurrent C. diff, fecal transplants, in a pill, which wouldn’t require a colonoscopy. Like probiotic supplements, it’s a gut bacteria product. Unlike the supplements, by the time it’s available it will have gone through the FDA wringer. It will contain about 50 strains of bacteria proven effective in treating C. diff and will require a doctor’s prescription.

Recurrent C. diff is an obvious entry point for Seres, said Chief Executive Officer Roger Pomerantz. “We asked, what is the lowest-hanging fruit?” But it’s hardly the end. The company has built a microbiome library of 14,000 strains of human bacteria it hopes will help it treat a range of diseases, eventually without needing feces at all.   Seres has embarked on the research with some pretty lofty goals, including finding treatments for obesity, liver disease, and cancer. It has partnerships with Massachusetts General Hospital, the Mayo Clinic, Memorial Sloan Kettering Cancer Center, and other respected medical institutions.  “We will figure out exactly what’s wrong with the microbiome, design a drug, and then pull the organisms out with our library, never touching a human donation,” Pomerantz said.    Seres’s lead product candidate, SER-109, will treat recurrent C. diff with four capsules taken orally instead of with transplants. While fecal matter is the raw material for the pills, the final product consists only of the spores necessary to treat the infection, which will have been extracted and purified.  SER-109 is expected to become the first oral microbiome therapy approved by the FDA, though Seres declined to predict exactly when it will arrive. Results from the latest trials are due by midyear, and Phase 3 trials are scheduled to follow later in the year. Seres hopes to follow up quickly with SER-287, a drug to treat ulcerative colitis, which could be the first microbiome drug to treat a chronic disease, and SER-262, to treat primary C. diff before it turns into the recurrent kind.

Other companies are racing to collect enough data for FDA approval, but right now Seres, which is publicly traded, looks to be the one to beat. “Seres is probably going to be the first one that’s going to knock at the FDA’s door,” said Mohan Iyer, chief business officer at Second Genome, a microbiome company studying how to treat disease with the compounds produced by gut bacteria instead of the gut bacteria themselves.

“SER-109 is poised to be first-in-class among fecal microbiota transplant-derived drugs,” Joseph Schwartz, an analyst at Leerink Partners, wrote in a May report. The report says the latest trial results “wowed the Street” but warns that the company could still be held back by “disappointing clinical data” and obstacles in the regulatory process.

#########

Another top contender is Rebiotix. Its RBX2660 is also designed to treat recurrent C. diff but, unlike SER-109, is administered with an enema; an oral version is in development. The treatment also differs significantly from Seres’s in formulation, including thousands of kinds of microbes from the donor’s stool, compared with SER-109’s 50 or so, as many as could be preserved and some of which haven’t even been identified.

“We make sure we have a minimum concentration of certain kinds that we know the patients lack,” CEO Lee Jones said. “But we don’t identify all of them. There’s no way to do that.” A recent study estimated that 1014 bacteria are in the human gut, most of which have never been isolated. Jones said the drug could hit the market by 2018.

######
  • UPDATES:

The medications have been shown to be similarly effective—with no C. diff-associated diarrhea for 29 of 30 of Seres’s patients  and  27 of 31 of Rebiotix’s, in the companies’ latest results—and equally safe. Adverse reactions for both are limited to such problems as moderate diarrhea and abdominal cramping, which could be from the C. diff itself. Both have been designated as “breakthrough therapies” by the FDA, allowing for an expedited approval process, and both are likely soon to provide an at-home alternative to fecal transplants.

#####

Point Of View:

“I don’t know who is going to make it across the line first,” said Gail Hecht, director of gastroenterology and nutrition at Loyola University Medical Center and chairwoman of the American Gastroenterological Association for Gut Microbiome Research & Education. Hecht has attended a Seres advisory board meeting but doesn’t have a financial interest in the company. “It is indeed a race,” she said.

Seres does have at least one distinct market advantage. “Patients have different preferences,” Hecht observes, but “in general, people don’t particularly like enemas.”

#####

Human Fecal Transplants:

For nearly two thousand years, doctors have looked to this unlikeliest of places for medicine. One of the earliest documented applications is from the fourth-century Chinese medical doctor Ge Hong, whose “yellow soup” recipe to treat diarrhea included a healthy person’s dried or fermented feces. Sixteen hundred years later, in 1958, patients infected with C. diff received the first known human fecal transplants.

Stool Bank Information: 

Today the effectiveness of fecal transplants (formally known as fecal microbiota transplants) to treat recurrent C. diff is supported by a long list of studies, with researchers attributing the results to the restoration of the microbiome. OpenBiome, a nonprofit stool bank, shipped 1,828 treatments in 2014, a number that ballooned to 7,140 treatments in 2015 and looks to be eclipsed this year, with 4,323 treatments shipped to its clinical partners through May 31. And these numbers don’t take into account the transplants performed through directed fecal donations.
