Seres Therapeutics and Nestle’ Health Science Team Up For the Joint Commercialization of Seres Therapeutics Investigational Microbiome Treatment for Recurrent C. difficile Infection (rCDI)

Seres Therapeutics and Nestlé Health Science have announced a decision to team up for the joint commercialization of Seres’s investigational oral microbiome treatment for recurrent Clostridioides difficile (C. difficile) infections (CDI).

Nestlé Health Science had previously received commercial rights to Seres’s therapeutics for inflammatory bowel disease and CDI, but only outside the U.S. and Canada. This expansion places Nestlé as Seres’s global collaborator for SER-109, a therapy the company hopes to treat a leading contributor to hospital-acquired infections in North America. If approved by the U.S. Food and Drug Administration (FDA), the agent, dubbed SER-109, will be the first microbiome therapeutic available.

Each year, CDI contributes to the deaths of 20,000 Americans. Standard of care for recurrent CDI includes the use of fecal microbial transplants. Currently, there is no microbiome therapies approved for any indications, which has created an unmet need recognized by an ever-growing list of pharmaceutical companies partnering with microbiome startups.

Seres’s investigational SER-109 includes purified Firmicutes spores; the rationale for including these spores is “based on their modulatory role in the life cycle of C. difficile and disease pathogenesis,” according to a statement made by the company.

Findings from the pivotal Phase III ECOSPOR III trial announced back in August 2020 showed SER-109 significantly reduced the CDI recurrence rate compared with placebo over an eight-week period. The absolute reduction of the CDI recurrence rate was 27% while the relative risk reduction was 68%. In addition, up to 88% of patients experienced a sustained clinical response by the end of the eight weeks.

Nestlé Health Science has agreed to use Aimmune Therapeutics, the company’s global pharmaceutical business, to lead the commercialization of the therapy. In return, Seres has agreed to receive upfront licensing payments totaling $175 million. An additional $125 million will be paid to Seres by Nestlé upon FDA approval of the microbiome agent.

Under terms of the agreement, Seres holds the sole responsibility for costs associated with development and pre-commercialization of SER-109 in the U.S. The company will be eligible to receive up to 50% of the commercial profits once the therapeutic is commercialized.

“Nestlé Health Science has been a terrific collaborator in our quest to develop a new treatment option for patients suffering from recurrent C. difficile infection, and their support over the past few years has been critical in advancing SER-109 to address this unmet need,” said Eric Shaff, Seres Therapeutics’ chief executive officer, in a statement. “As we prepare for potential approval and commercialization, we are eager to embark side-by-side on our next phase with a company that believes as fervently as we do in the potential of this transformative approach to reduce the recurrence of CDI.”

Nestlé Health Science’s CEO, Greg Behar, added that the company “is focused on the fast-developing areas of gut health, food allergies and metabolic health within our global pharmaceutical business, Aimmune Therapeutics.” As such, Aimmune’s “fully integrated commercial infrastructure” will be leveraged to launch the therapy, pending approval.

Seres has been busy this year in moving its investigational microbiome therapy pipeline in front of the FDA. Last month, Seres announced the agency had cleared an Investigational New Drug application for the company’s other investigational microbiome therapeutic for preventing antibiotic-resistant bacterial infections as well as graft-versus-host disease.

The company is advancing SER-155 into a Phase Ib trial under a collaboration with Memorial Sloan Kettering Cancer Center. “SER-155 represents a novel microbiome technology with the potential to address antibiotic-resistant bacterial bloodstream infections and further to modulate host immunomodulatory responses to decrease graft-versus-host disease,” said Seres’s chief scientific officer, Matthew Henn, Ph.D., in a statement.

Seres Therapeutics To Host a Virtual Webcast Focused on SER-109 on May 27, 2020

In The News:

Seres Therapeutics to Host Virtual SER-109 Focused Symposium on May 27, 2020, Ahead of Phase 3 ECOSPOR III Study Read-Out

– Data from SER-109 Phase 3 study in recurrent C. difficile infection expected mid-2020 –

Seres Therapeutics, Inc.  announced that it will host a virtual webcast symposium focused on SER-109 as a potential new therapeutic option for recurrent Clostridioides difficile infection (CDI) on Wednesday,  May 27, 2020 from 8:30 to 9:30 a.m. ET.

During the event, Mark Wilcox, M.D., Professor of Medical Microbiology, University of Leeds, and Seres’ management will discuss the CDI patient burden, the ongoing SER-109 Phase 3 ECOSPOR III study and the potential for SER-109 to become the standard of care for recurrent CDI.

SER-109 is being evaluated in an ongoing Phase 3 study for the prevention of recurrence of CDI. SER-109 has obtained both Breakthrough Therapy Designation and Orphan Drug Designation from the U.S. Food and Drug Administration (FDA).

Seres previously reported the completion of enrollment in the Phase 3 ECOSPOR III study (ClinicalTrials.gov identifier: NCT03183128), a multicenter, randomized 1:1, placebo-controlled study in patients with multiply recurrent CDI. ECOSPOR III has enrolled 182 patients. Seres expects to report SER-109 Phase 3 top-line results in mid-2020.

Based on prior discussions with the FDA, Seres believes that ECOSPOR III has the potential to be the single pivotal study supporting product registration; however, this will depend on the strength of the data, and additional safety data may be required. If approved, SER-109 has the potential to be the first FDA-approved therapy for CDI to treat the underlying cause of this disease, and the first approved microbiome drug for any human condition.

Seres Therapeutics SER-109 Phase 3 Clinical Study For Recurrent C. diff. Infection Initiated

Seres Therapeutics Initiates SER-109 Phase 3 Study in Patients with Multiply

Recurrent C. difficile Infection

 

Jun. 12, 2017– Seres Therapeutics, Inc.

announced the initiation of its Phase 3 SER-109 clinical study (ECOSPOR III) in patients with multiply recurrent C. difficile infection. Based on recent interactions with the U.S. Food and Drug Administration (FDA), ECOSPOR III will now be designated a Phase 3 trial and the company expects that this single pivotal study may support SER-109 registration and approval.

“We are extremely pleased to be able to initiate the SER-109 Phase 3 ECOSPOR III study. If ECOSPOR III is successful, we believe this study could serve as the basis for SER-109 approval. Our goal is to have SER-109 approved as the first microbiome drug in this new field of medicine, and the first for patients with multiply recurrent C. difficile infection, an area of very high unmet need for patients in the U.S. and around the world,” said Roger J. Pomerantz, M.D., President, CEO and Chairman of Seres.

The ECOSPOR III Phase 3 study design incorporates direct learnings from prior SER-109 development efforts, as well as helpful feedback obtained from the FDA and study investigators. The study is expected to enroll approximately 320 patients with multiply recurrent C. difficile infection, randomized 1:1 to either SER-109 or placebo. The study is sized to contribute to an adequate safety database that may support product licensure. ECOSPOR III will utilize more than 100 clinical sites across the U.S. and Canada. The study’s primary endpoint will compare the reduction of C. difficile recurrence rates in subjects who receive SER-109 verses placebo at up to eight weeks after dosing.

The initiation of the SER-109 Phase 3 ECOSPOR III study triggers a $20 million milestone payment under the company’s previously announced development and commercialization collaboration agreement with Nestlé Health Science. In partnership with Nestlé Health Science, Seres plans to accelerate interactions with European regulatory agencies in the coming months to establish a path toward SER-109 product approval across Europe.

Seres Therapeutics, Inc. Announced That It Has Initiated a Phase 1b Clinical Trial Evaluating SER-262 In Patients With Primary C. diff. Infection (CDI)

Seres Therapeutics Inc.  a leading microbiome therapeutics company, announced today 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.

“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.”

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.

With the initiation of the SER-262 Phase 1b study in primary CDI, and the ongoing SER-109 Phase 2 study in multiply recurrent CDI, Seres now has ongoing microbiome clinical programs across the entire CDI population. Initial study results from the SER-109 Phase 2 study are expected in mid-2016.

C. diff. Prevention of Recurrent C. diff. Infection (RCDI), Seres Therapeutics Announces Achievement of Target Enrollment of SER-109 Phase 2 Study

In The News: May 2, 2016

Seres Therapeutics Announces Achievement of Target Enrollment of SER-109 Phase 2 Study for the Prevention of Recurrent Clostridium difficile Infection

Phase 2 data expected in mid-2016

New SER-109 Expanded Access Program initiated at Phase 2 clinical sites

Seres Therapeutics, Inc.  a leading microbiome therapeutics platform company, announced that the target enrollment of 87 patients has been achieved for its ongoing SER-109 Phase 2 clinical study.

SER-109 is an oral, potential first-in-field microbiome therapeutic that has been granted Orphan Drug and Breakthrough Therapy designations by the U.S. Food and Drug Administration (FDA), and is being investigated for use in preventing recurrent Clostridium difficile infection (CDI).

“We are pleased to reach this important milestone in our ongoing development of SER-109, which has the potential to be the first therapy for C. difficile infection to treat the underlying cause of this disease, and the first microbiome drug for a human disease. This is the first placebo controlled trial for patients with multiply-recurrent CDI,” said Roger Pomerantz, M.D., Chairman, President, and CEO of Seres. “C. difficile infection is an extremely serious condition responsible for approximately 29,000 deaths each year in the United States alone. We are moving with urgency to develop SER-109 as quickly and safely as possible. We expect initial results of the Phase 2 study in the middle of this year, and we plan to initiate a Phase 3 study later in 2016.”

The SER-109 Phase 2 study (ClinicalTrials.gov identifier: NCT02437487) is a multicenter, randomized, placebo-controlled study being conducted at approximately 40 centers across the U.S. The current study builds on a completed, successful Phase 1b/2 trial, which demonstrated that 87 percent of patients (26 of 30) met the predefined endpoint of preventing recurrent CDI within eight weeks following administration of SER-109. In that study 97 percent of patients (29 of 30) achieved a clinical cure during the eight-week period after SER-109 dosing, as defined by the absence of CDI requiring antibiotic treatment. Results from the Phase 1b/2 have been published in The Journal of Infectious Disease.1

The Company has initiated a SER-109 Expanded Access Program at selected sites participating in the ongoing Phase 2 study. The Expanded Access Program will enable eligible patients with multiply-recurrent CDI to have continued access to SER-109. Furthermore, maintaining Phase 2 study sites open ahead of the anticipated start of the Phase 3 study expected to support and augment Phase 3 study execution and enrollment.
