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.

To join the live webcast, on May 27, 2020 at 8:30 a.m. ET, including presentation slides, please visit the “Investors & Media” section of the Seres website at www.serestherapeutics.com.

SER-109 is an oral, first-in-field microbiome therapeutic candidate 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 have achieved this critically important corporate milestone. SER-109 has the potential to be the first FDA-approved therapy for C. difficile infection to treat the underlying cause of this disease, and the first approved microbiome drug for any human condition. We believe SER-109 could fundamentally transform the treatment of patients with recurrent C. difficile infection, a life-altering infectious disease, and we eagerly look forward to topline clinical results in the middle of this year. With compelling Phase 3 ECOSPOR III clinical data, we plan to engage in discussions with the FDA regarding a filing for product approval,” said Eric Shaff, President and Chief Executive Officer of Seres. “We are also working to advance our other promising clinical development candidates in light of the COVID-19 pandemic. This remains an evolving situation and we are carefully reviewing our development plans to determine how to rapidly advance our pipeline toward high-quality data readouts.”

SER-109 Study Updates

The SER-109 Phase 3 ECOSPOR III study (ClinicalTrials.gov identifier: NCT03183128) is a multicenter, randomized, placebo-controlled study which has enrolled 181 patients with multiply recurrent CDI to date. ECOSPOR III had been designed to enroll 188 patients. The Company has decided to halt enrollment as a result of the COVID-19 pandemic. Seres believes that ECOSPOR III remains well-powered to evaluate the efficacy of SER-109. The ECOSPOR III study’s primary endpoint is the reduction of CDI recurrence at up to eight weeks following SER-109 administration, and the Company expects to report study results in mid-2020 as had been planned.

Seres is grateful to the patients, principal investigators and clinical research teams who participated in ECOSPOR III, many of whom are now involved in the fight against COVID-19.

The SER-109 Phase 3 ECOSPOR III study includes use of an objective Clostridium difficile cytotoxin assay to ensure that all patients entering the study have active CDI, as well as to confirm CDI recurrences during the study (i.e., the ECOSPOR III primary endpoint).

Seres plans to initiate a SER-109 Expanded Access Program at selected clinical sites participating in the ongoing Phase 3 ECOSPOR III study, and the Company may also initiate the program at additional clinical sites for eligible patients to have access to SER-109.

Prior completed clinical studies have demonstrated SER-109 bacterial engraftment into the gastrointestinal microbiome, and that engraftment is associated with reduced recurrence of CDI. In all prior clinical studies, SER-109 was associated with a favorable safety profile.

The FDA has issued several safety alerts related to Fecal Microbiota Transplantation (FMT) and the risk of pathogen transmission including warnings related to Multi-Drug Resistant Organisms and SARS-CoV-2, the virus linked to COVID-19 (June 12, 2019Alert; March 12, 2020Alert; and March 23, 2020Alert). Unapproved FMT is widely used under an FDA Enforcement Discretion policy for the treatment of recurrent CDI that is not responsive to standard therapies.

In contrast to FMT, SER-109 is comprised of a highly purified consortia of spore-based commensal bacteria and is manufactured under Good Manufacturing Practices (GMP) conditions using stringent standards to ensure product quality and consistency. Seres utilizes a unique manufacturing process which has been demonstrated to inactivate numerous potential pathogens, including species of non-spore bacteria, such as Escherichia coli, and viruses. The Company’s manufacturing process inactivates many emerging potential pathogens where diagnostic assays may not yet be available, such as SARS-CoV-2. Seres has issued a position statement highlighting the criticality of including pathogen inactivation processes in the manufacture of microbiome therapeutics. Recent discussions with the FDA have indicated agency support regarding the fundamental differentiation between FMT and Seres’ product candidates.

COVID-19 Impact and Other Clinical Program Updates

Seres continues to monitor the impact of the COVID-19 pandemic on Company operations and ongoing clinical development activity, including the SER-287 Phase 2b study in ulcerative colitis, the SER-401 Phase 1b study in metastatic melanoma, and SER-301, a rationally designed, fermented development candidate for ulcerative colitis. Mitigation activities to minimize COVID-19-related operation disruptions are ongoing; however, given the severity and evolving nature of the situation, the timing of SER-287 Phase 2b and SER-401 Phase 1b clinical readouts is uncertain. Seres does not anticipate disruptions to the availability of its drug product candidates for ongoing studies.

The SER-287 Phase 2b study is currently approximately 60% enrolled based on the 201-patient target study size. SER-287 development activity has been adversely impacted by multiple clinical sites halting non-essential procedures, including endoscopies, which may make it difficult to achieve the original enrollment target in H2 2020 as planned. Seres is evaluating enrollment mitigation strategies and possible trial design modifications with the goal of obtaining a high-quality, clinically meaningful dataset within a timeframe consistent with Seres’ prior guidance for its cash runway extending into the second quarter of 2021. Furthermore, the Company is encouraged by the FDA’s indications of flexibility in light of the COVID-19 pandemic, and plans to engage the FDA in discussions regarding any potential trial modifications.

Seres continues to execute on activities to advance SER-301 clinical development and the planned initiation of patient dosing in Australia and New Zealand later this year.

Seres Therapeutics SER-109, Investigational Microbiome Drug to Reduce rCDI, What Was Learned From a Phase 2 Clinical Trial

Abstract

Background

Recurrent C. difficile infection (rCDI) is associated with loss of microbial diversity and microbe-derived secondary bile acids, which inhibit C. difficile germination and growth. SER-109, an investigational microbiome drug of donor-derived, purified spores, reduced recurrence in a dose-ranging, open-label Phase (Ph)1 study in subjects with multiply rCDI.

Methods

In a Ph2 double-blind trial, subjects with clinical resolution on standard-of-care antibiotics were stratified by age (< or ≥65 years) and randomized 2:1 to single-dose SER-109 or placebo. Subjects were diagnosed at study entry by PCR or toxin testing. Safety, C. difficile-positive diarrhea through week 8, SER-109 engraftment and bile acid changes were assessed.

Results

89 subjects were enrolled; 67% were female; 80.9% diagnosed by PCR. rCDI rates were lower in the SER-109 arm than placebo (44.1% versus 53.3%, respectively) but did not meet statistical significance. In a pre-planned analysis, rates were reduced among subjects ≥65 years (45.2% versus 80%, respectively; RR:1.77, 95% CI:1.11-2.81) while the <65 group showed no benefit. Early engraftment of SER-109 was associated with non-recurrence (p <0.05) and increased secondary bile acid concentrations (p<0.0001). Whole metagenomic sequencing from this study and our prior Ph1 study revealed previously unappreciated dose-dependent engraftment kinetics and confirmed an association between early engraftment and nonrecurrence. Engraftment kinetics suggest that Ph2 dosing was suboptimal. Adverse events were generally mild-to-moderate in severity.

Conclusions

Early SER-109 engraftment was associated with reduced CDI recurrence and favorable safety was observed. A higher dose of SER-109 and requirements for toxin testing were implemented in the current Ph3 trial.

Seres Therapeutics Announces a New SER-109 Phase 2 Clinical Study (ECOSPOR III) For Patients With Multiple Recurrent C. diff. Infections (CDI’s)

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 Share Key Findings From Earlier Reported SER-109 Phase 2 Clinical Study Outcome

seres-therapeutics-inc-logo

As published in Seres Therapeutics Press Release  January 31, 2017

 

Findings suggest that both misdiagnosis of C. difficile recurrent infection in some patients, and dosing that may have been suboptimal in certain patients, contributed to the previously reported SER-109 Phase 2 study outcome –

FDA discussions are ongoing regarding a new, redesigned clinical study for SER-109

CAMBRIDGE, Mass., On January 31, 2017 —Seres Therapeutics Inc., a leading microbiome
therapeutics platform company, reported that it has completed in-depth analyses of the previously reported SER-109 Phase 2, eight-week clinical study data in patients with multiply recurrent Clostridium difficile infection.

The company also reported the full, 24-week SER-109 Phase 2 study results and open label extension study data.

“Since obtaining the unexpected SER-109 clinical study results last summer, we have undertaken a comprehensive assessment of the program to understand the reasons for the results,” said Roger J. Pomerantz, M.D., President, CEO and Chairman of Seres.

“We have now identified specific factors that we believe contributed to the Phase 2 results, including issues related to both the accurate diagnosis of C. difficile recurrent infection, and potential suboptimal dosing of certain subjects in the trial. The SER-109 analyses were recently shared with the FDA, and we are actively discussing the design of a new clinical trial for SER-109. There remains a compelling need for an effective, safe, and convenient FDA approved therapy for patients with recurrent C. difficile infection, and this investigation provides insights to guide further clinical development of SER-109.”

Investigation Summary: C. difficile Diagnosis: Analysis was conducted to evaluate both the role of C. difficile diagnostic testing in defining the correct SER-109 Phase 2 study entry population, and in the proper diagnosis of C. difficile recurrences during the study. In the Phase 2 study, 81% of study subjects (72 of 89 subjects) were enrolled based on polymerase chain reaction (PCR) based testing for C. difficile, as well as clinical evaluation. An important and increasingly well-appreciated limitation of PCR testing is that while a positive result indicates that C. difficile cytotoxin genes are present, a positive PCR test does not necessarily indicate thatthe organism is viable and producing disease causing cytotoxins, nor that
C. difficile is the source of clinical symptoms.1

Two separate observations were made pertaining to the effects of discordant results from PCR and cytotoxin assay on the SER-109 trial. The qualifying stool samples evaluated for Phase 2 study entry were not available for retesting for cytotoxin, however, the company was able to retest the samples associated with patients entering the open label extension trial for the presence of the C. difficile cytotoxin and determined that only 44% of samples (15 of 31 subjects) that tested positive by PCR testing also tested positive based on C. difficile cytotoxin assay. These results suggest that a substantial proportion of patients who entered the SER-109 Phase 2 study may have been C. difficile carriers and, therefore, C. difficile infection may not have been the source of the clinical symptoms. In addition, data from this analysis suggest that the use of PCR to measure C. difficile may have overestimated study recurrences in both treatment arms of the Phase 2 trial, further complicating interpretation of study results. This was shown by reanalysis of samples with cytotoxin assay, from patients diagnosed as recurrent in the Phase 2 study. In this retesting, between one quarter andone half of presumed study recurrences may not have been true C. difficile infections leading to pathology.

From the analyses described above, the company believes that misdiagnoses may have occurred both in some patients entering the SER-109 trial, as well as for recurrences diagnosed during the trial.

SER-109 Pharmacokinetics, Pharmacodynamics, & Dosing

The company performed an in-depth analysis to examine SER-109 biological activity in the Phase 2 trial, as measured by microbiome changes in patients and downstream biological effects in the gastrointestinal tract. Results demonstrated a statistically significant increase in the richness of commensal spore-forming bacterial species in patients treated with SER-109, as compared to those receiving placebo. These data demonstrate that SER-109 successfully engrafted and was biologically active in the Phase 2 study. In addition, among those patients with an increased prevalence of specific SER-109 associated bacterial species, a decreasedrate of high confidence recurrences (i.e., recurrences confirmed by C. difficile cytotoxin assay) was demonstrated.

The company also assessed whether the SER-109 dose impacted the degree of microbiome changes observed. All Phase 2 patients received 1 X 10 8 bacterial spores, whereas patients in the prior SER-109 Phase 1b open label study received doses ranging approximately 700-fold, from 3 X 107 to 2 X 109 spores. The company also performed high-resolution whole metagenomics sequencing of stool samples collected from patients in both the SER-109 Phase 1b, as well as the Phase 2 trial as part of this analysis. The analysis indicated that subjects in the open-label Phase 1b study who received a higher dose achieved a significantly greater increase in diversity of commensal spore-former bacteria by 1 week post-treatment, as compared to both Phase 1b and Phase 2 subjects treated with lower doses. These results suggest that the dose used in the SER-109 Phase 2 study may have been suboptimal in certain patients, and may have resulted in a less robust drug effect, contributing to decreased efficacy in Phase 2, as compared to the Phase 1b study.

Much of the SER-109 Phase 2 microbiome-related learnings are based on advancements in the computational analytics and higher resolution whole metagenomics sequencing techniques that Seres is pioneering, and several of these methods were developed after the SER-109 Phase 2 study was designed. Insights obtained from this work may also
benefit Seres’ broad preclinical and clinical microbiome development pipeline.

Analysis of SER-109 Phase 2 Study Clinical Drug Product

The company also conducted a thorough and detailed investigation of the potential impacts of manufacturing and formulation changes implemented in the Phase 2 study. No issues regarding product quality or formulation were identified which would have impacted the Phase 2 study results.

Summary of SER-109 24-Week and Open Label Extension Study Results

The full, 24-week Phase 2 study results continue to demonstrate that SER-109 was generally well tolerated. The most common adverse events associated with SER-109 included diarrhea, abdominal pain and flatulence. The Phase 2 study population represented older individuals, many in poor health, and a high rate of serious adverse events (SAEs) was reported in both study arms. A numerically higher rate of SAEs was observed in the SER-109 arm (15.0% versus 10.3% for placebo), however there was no detectable pattern in the SAEs observed, and none of these were considered to be SER-109 drug-related by the study investigators.

As expected with recurrent C. difficile infection, relatively few additional recurrences occurred beyond 8 weeks, and the 24-week data provides relatively little new information regarding efficacy. Based on 24-week data, five further patients recurred in the SER-109 arm, but three of the five recurrences (60%) were in patients who terminated the trial early, resulting in an imputed recurrence. In the placebo arm, one patient also terminated the trial early, resulting in an imputed recurrence. Early terminations, and loss of patients to follow-up, are common in the long safety follow-up portions of clinical trials.

Phase 2 study subjects who experienced a C. difficile recurrence had the option to enroll in an open label extension study, where they were treated with SER-109 and were followed for an additional 24 weeks. In total, 34 patients entered the open label extension study and 11 patients recurred during the initial 8-week study period, a 32% recurrence rate.
