Current report
We are a clinical-stage company focused on improving patient outcomes in medically vulnerable populations through novel live biotherapeutics. We led the successful development and approval of VOWST, the first FDA-approved orally administered microbiome therapeutic, which was sold to Société des Produits Nestlé S.A., or SPN, and with certain of its affiliates, collectively, Nestlé Health Science, in September 2024. We are progressing the development of SER-155, an investigational, oral, live biotherapeutic designed to decolonize gastrointestinal, or GI, pathogens, improve epithelial barrier integrity, and induce immune tolerance to prevent bacterial bloodstream and antimicrobial resistant, or AMR, infections as well as other pathogen-associated negative clinical outcomes in patients undergoing allogeneic hematopoietic stem cell transplantation, or allo-HSCT. The placebo-controlled Phase 1b study Cohort 2 results demonstrated that SER-155 was associated with a significant reduction in both bloodstream infections and systemic antibiotic exposure as well as a lower incidence of febrile neutropenia, as compared to placebo through day 100 post HSCT. SER-155 was generally well tolerated, with no observed treatment-related serious adverse events. SER-155 and our other pipeline programs are designed to target multiple disease-relevant pathways and are manufactured from standard clonal cell banks via single-strain cultivation, rather than from the donor-sourced production process used for VOWST.

The contingent liabilities include $16.9 million associated with the Profit Sharing Payments, $2.6 million associated with the MSK Agreement, $6.6 million and $3.0 million related to the settlement of the collaboration payable to SPN for the quarters ended June 30, 2024 and September 30, 2024, respectively, $1.9 million associated with our obligation to pay 80.1% of the costs associated with the lease of the Waltham facility through December 31, 2025, $1.5 million associated with certain employment-related costs for conveying employees, and $1.0 million associated with our ongoing post-marketing safety study of VOWST. The contingent liabilities will be remeasured at each reporting period based on (i) cash payments made by the Company to reduce the accrued liabilities due to SPN and (ii) revised estimates of the total remaining liabilities due to SPN.
Current report
SER-155 Phase 1b Study
Current report
SER-155 has been evaluated in a Phase 1b placebo-controlled study in patients undergoing allo-HSCT. The SER-155 Phase 1b study included two cohorts. Cohort 1 was designed to assess safety and drug pharmacology, specifically the drug strain engraftment in the gastrointestinal tract. Cohort 1 included 13 subjects who received any dosing of the SER-155 regimen, with 11 subjects subsequently receiving an allo-HSCT. Results from this cohort, announced in May 2023, showed SER-155 was generally well tolerated and resulted in successful drug strain engraftment and a reduction in pathogen domination in the GI microbiome relative to a historical control cohort.
Current report
Study Cohort 2 utilized a randomized, double-blinded 1:1 placebo-controlled design to further evaluate safety and drug strain engraftment, as well as key secondary and exploratory endpoints such as the incidence of bacterial bloodstream infections and related medical consequences such as febrile neutropenia and antibiotic use. Cohort 2 included 45 patients in the intention-to-treat (ITT) population. Of the ITT population, 20 received SER-155 and 14 received placebo, each of whom subsequently received an allo-HSCT, with data available for clinical evaluation through day 100, the study’s prespecified primary observation point. Exploratory hypothesis testing was conducted at the two-sided α=0.05 level. Ninety-five percent (95%) 2-sided confidence intervals (CIs) were determined, where specified. No adjustment for multiplicity was done. A subset of patient samples was available for drug pharmacology analysis.
Current report
The median age in Cohort 2 was 63, and most subjects had acute myeloid leukemia, acute lymphocytic leukemia, myelodysplastic syndrome or myeloproliferative neoplasia as their primary disease and received reduced-intensity conditioning pre-transplant. Most patients received peripheral blood stem cells from a matched unrelated donor. A majority received post-transplant cyclophosphamide as part of their graft-versus-host disease (GvHD) prophylaxis.
Current report
Results from Cohort 2, announced in September 2024, were consistent with the observations from Cohort 1. SER-155 was generally well tolerated, and no treatment-emergent serious adverse events related to drug were observed. SER-155 bacterial strains engrafted into the gastrointestinal tract of patients following the administration of SER-155.
Current report
The incidence of BSIs was significantly lower in the SER-155 arm compared with the placebo arm (2/20 (10%) vs. 6/14 (42.9%), respectively; [Odds Ratio: 0.15; 95% CI: 0.01, 1.13, p=0.0423]), which represents a relative risk reduction of approximately 77% and an absolute risk reduction of approximately 33%. In addition, while antibiotic starts were similar in each arm, patients administered SER-155 were treated with antibiotics for a significantly shorter duration compared to patients in the placebo arm (9.2 days vs. 21.1 days, respectively, with a mean difference of -11.9 days [95% CI: -23.85, -0.04; p=0.0494]). The incidence of febrile neutropenia was lower in patients administered SER-155 compared to placebo (65% vs. 78.6%, respectively; [Odds Ratio: 0.51; 95% CI: 0.07, 2.99; p=0.4674]). Six cases of gastrointestinal infections (C. difficile infections) were observed in the study, with four cases (20%) in the SER-155 arm and two cases (14.3%) in the placebo arm.
Current report
Recent changes in the allo-HSCT standard of care and the increasing use of post-transplant cyclophosphamide as part of prophylactic therapy for GvHD have reduced rates of GvHD overall in this patient population. The rates of GvHD in the study were low, with two cases of grade 2 GvHD observed in each arm, and no cases of grade 3 or 4 GvHD were observed.
Current report
In Cohort 2, the ability to detect pathogen domination (i.e., relative abundance in the GI ≥30%) in the placebo arm, and differences between the study arms, was constrained due to the limited number of placebo stool samples and an imbalance in the number of available stool samples between the arms. Observed pathogen domination events were low in the placebo and SER-155 arms with no significant differences identified. In a comparison of the prevalence of pathogen domination versus a larger allo-HSCT historical control cohort, pathogen domination in SER-155 subjects was substantially lower, providing further evidence of SER-155 activity.
Current report
If we do not regain compliance with the Bid Price Requirement by May 6, 2025, we may be eligible for an additional 180 calendar day compliance period. To qualify, we must submit an application to transfer the listing of the common stock to The Nasdaq Capital Market, which requires us to meet the continued listing requirement for the market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, other than the Bid Price Requirement.

Previous report
We are a commercial-stage company focused on the development and commercialization of a novel class of biological drugs, which are designed to treat disease by modulating the microbiome to restore health by repairing the function of a disrupted microbiome to a non-disease state. Our first drug, VOWST, formerly called SER-109, was approved by the U.S. Food and Drug Administration, or FDA, on April 26, 2023, to prevent recurrence of Clostridioides difficile infection, or CDI, in patients 18 or older following antibacterial treatment for recurrent CDI. Our drug discovery and development pipeline includes other pre-clinical and clinical-stage assets. VOWST and our live biotherapeutic candidates are consortia of bacteria designed to optimize specific, targeted pharmacological properties, and are formulated for oral delivery. We maintain a differentiated live biotherapeutics drug discovery and development platform that includes good manufacturing practices, or GMP, manufacturing capabilities for this novel drug modality.
Previous report
Study cohort 1, which included 13 participants, was designed to assess safety and drug pharmacology, including the engraftment of drug bacteria in the gastrointestinal tract. In May 2023, we announced the Phase 1b cohort 1 results, including gastrointestinal microbiome data from the first 100 days, which showed the successful engraftment of SER-155 bacterial strains in all nine subjects with evaluable microbiome samples, and a substantial reduction in the cumulative incidence of pathogen domination (a biomarker associated with the risk of serious enteric infections and resulting bloodstream infections, as well as GvHD) as compared to a reference cohort of patients in this patient population. The tolerability profile observed was favorable, with no serious adverse events attributed to SER-155 administration. Enrollment in study cohort 2, which includes 45 participants, is complete as of April 2024. Study cohort 2 incorporates a randomized, double-blinded placebo-controlled 1:1 design to further evaluate safety and engraftment as well as clinical outcomes, and data readout is anticipated in September 2024.
Previous report
We believe our pending clinical and drug pharmacology results, if positive, will validate the promise of live biotherapeutics to prevent poor clinical outcomes associated with the overgrowth of pathogens in the GI tract of allo-HSCT patients. Additionally, we believe the SER-155 Phase 1b program will provide important insights into the safety profile of live biotherapeutics in immunocompromised patients and additionally into mechanisms by which live biotherapeutics can modulate host immune pathways. We intend to evaluate SER-155 and other live biotherapeutic candidates in several other medically vulnerable patient populations at high risk of infections, including chronic liver disease, cancer neutropenia, and solid organ transplants.

VOWST
Previous report
VOWST (previously referred to as SER-109) was approved by the FDA on April 26, 2023, to prevent recurrence of CDI in individuals 18 years of age or older following antibacterial treatment for recurrent CDI. VOWST is the first FDA-approved orally administered microbiome therapeutic, and consists of a consortium of purified Firmicutes spores designed to prevent recurrent CDI in patients with a history of CDI by modulating the microbiome to a state that resists C. difficile germination and growth. The VOWST manufacturing purification process is designed to remove unwanted microbes in an effort to reduce the risk of pathogen transmission beyond donor screening alone. We estimate that there were approximately 156,000 recurrent CDI cases in the United States during 2023 and that this number will grow at an annual rate of 2%.
Previous report
We launched VOWST in the United States with our collaborator, Nestlé Health Science, in June 2023. Under the terms of the 2021 License Agreement, Nestlé Health Science assumed the role of lead commercialization party. We received an upfront license payment of $175 million in July 2021 and an additional $125 million in May 2023 following FDA approval of VOWST. The agreement also includes sales target milestones which, if achieved, could total up to $225 million. We were responsible for development and pre-commercialization costs in the United States. Following first commercial sale of VOWST, which occurred on June 2, 2023, we are entitled to share equally in its commercial profits and losses.
Previous report
During the quarter ended June 30, 2024, Nestlé Health Science reported $14.4 million in VOWST net sales. The total collaboration loss for the three months ended June 30, 2024 was $13.3 million. We record our 50% share of the collaboration loss, which includes commercial and medical affairs expenses incurred by us, on a net basis. Accordingly for the quarter ended June 30, 2024, our share of the VOWST net loss was $6.6 million.
Previous report
Concurrently with the execution of the Purchase Agreement, our directors and executive officers and certain stockholders affiliated with Flagship Pioneering, Inc. entered into support agreements with us and SPN, or the Support Agreements, pursuant to which, among other things and subject to the terms and conditions therein, such parties agreed, solely in their capacities as holders of shares of common stock, or collectively, the Subject Shares, to vote all Subject Shares beneficially owned by such parties at every meeting of our stockholders (including the special meeting to consider the transactions contemplated by the Purchase Agreement) (i) in favor of adopting and approving the Purchase Agreement and the transactions contemplated by the Purchase Agreement, (ii) against any proposal that would otherwise be reasonably be expected to adversely affect the transactions contemplated by the Purchase Agreement, (iii) against any Acquisition Proposal (as defined therein), and (iv) in favor of approving any proposal to adjourn or postpone the special meeting of stockholders to a later date, if there are not sufficient votes for the adoption of the Purchase Agreement on the date on which such meeting is held. In addition, each stockholder party to a Support Agreement provided an irrevocable proxy to SPN to vote such party’s Subject Shares in favor of adopting and approving the Purchase Agreement and the transactions contemplated by the Purchase Agreement.
Previous report
Until the completion of the Transaction, if consummated, we will continue to monitor the commercialization of VOWST. Broad demand for VOWST has been observed across both recurrent patients and healthcare providers since it became commercially available in June 2023 (metrics noted below are based on data provided by Nestlé through June 30, 2024):
Previous report
In the second quarter of 2024, approximately 1,522 completed prescription enrollment forms were received for VOWST; of those, 1,169 resulted in new patient starts by June 30, 2024;
Previous report
From launch through June 30, 2024, there were 5,757 completed prescription enrollment forms received for VOWST; of those 4,265 resulted in new patient starts by June 30, 2024;
Previous report
Prescription enrollment forms were submitted by approximately 2,452 unique healthcare providers since launch, including 708 in the second quarter, with approximately 67% of enrollments from gastroenterology and the remainder from other specialties; approximately 864 HCPs have prescribed VOWST to more than one patient; and
Previous report
VOWST demand has been observed across the recurrent CDI patient pool, including first recurrence, which is the largest recurrent CDI patient segment.
Previous report
During the second quarter of 2024, Nestlé Health Science continued to scale its HCP education efforts. Since the FDA approval of VOWST, Nestlé Health Science commercial customer facing field teams have been promoting VOWST and generating healthcare provider demand. Nestlé Health Science’s 170 field sales representatives promoting VOWST are divided into two teams, comprised of 150 gastroenterology representatives and 20 hospital/infectious disease representatives. In the first quarter of 2024, Nestlé Health Science identified opportunities to refine the execution of these teams in terms of focusing promotional messaging on early use of VOWST in the recurrent CDI cycle and increasing the number of HCPs that the sales teams engage. We expect these efforts to accelerate demand for VOWST in the second half of 2024.
Previous report
The VOWST Voyage Support Program, or VOWST Voyage, was launched upon VOWST FDA approval to provide treatment and financial support for eligible patients. The VOWST Voyage staff work with healthcare providers and patients to convert patient enrollments into new patient starts and provide a robust high-touch customer experience.
Previous report
Nestlé Health Science’s payer field team continues to engage payers to build coverage, which would enable eligible patients to have access to VOWST as quickly and efficiently as possible. As of June 30, 2024, coverage policies were issued for VOWST across approximately 93% of commercial and 61% of Medicare Part D covered lives, according to data provided by Nestlé Health Science. The larger health plans and Pharmacy Benefit Managers, or PBMs, have issued policies for VOWST, and the remainder of smaller plans are extending the new-to-market block phase, enabling approval of VOWST as claims arise. Approximately 61% of the 1,169 second quarter new patient starts are being reimbursed through the patient's drug benefit.
Previous report
We are investing in patient financial assistance to increase access to VOWST for patients with affordability challenges due to co-pays or other cost sharing requirements imposed on them by their insurer after the prescription has been approved. We believe that providing this type of patient access early on will contribute to a positive patient and provider experience, thus increasing demand over time. In terms of free drug utilization, in the second quarter of 2024, we saw approximately 39% of new patient starts dispensed via our free drug programs, mostly for Medicare patients. We expect utilization of these programs to drop further when the benefit design changes contained in the Inflation Reduction Act, which address patient cost sharing requirements in Medicare Part D plans, go into effect in 2025.
Previous report
VOWST was previously granted Breakthrough Therapy and Orphan Drug Designations by the FDA. In connection with the FDA approval of VOWST, we received seven years of orphan-drug exclusivity, which began on April 26, 2023. During that time, VOWST is entitled to a period of marketing exclusivity, which precludes the FDA or other regulatory authorities from approving another marketing application for the same drug or biologic for the same disease or condition during that time period, except under certain circumstances.
Previous report
The FDA approval of VOWST was supported by the Phase 3 development program that included the ECOSPOR III and ECOSPOR IV studies. ECOSPOR III was a multicenter, randomized, placebo-controlled study that enrolled 182 patients with multiply recurrent CDI. All patients who entered ECOSPOR III must have tested positive for C. difficile toxin. This inclusion criterion was implemented in an effort to ensure enrollment of only patients with active infection rather than simple colonization. The study was designed to evaluate patients for 24 weeks, with the primary endpoint comparing the C. difficile recurrence rate in subjects who received SER-109 verses placebo at up to eight weeks after dosing.
Previous report
ECOSPOR III data demonstrated that the study achieved its primary endpoint where SER-109 was superior to placebo in reducing CDI recurrence at eight weeks, reflecting a recurrence-free rate of approximately 88% at eight weeks post-treatment. SER-109 resulted in a 27% absolute reduction of recurrence of CDI compared to placebo at eight weeks post-treatment, which is a relative risk reduction of 68%. The rate of recurrence at 12 weeks in the SER-109 arm was 18.0%, compared to a rate of 46.2% in the placebo arm, representing an absolute risk reduction of 28% (relative risk 0.40; 95% CI 0.24-0.65), and thereby consistent with the results seen at eight weeks. The efficacy results remained durable through 24 weeks of follow-up, as SER-109 was observed to significantly reduced recurrence rates compared to placebo over 24 weeks, 21.3% vs. 47.3%, respectively. These data were published in the New England Journal of Medicine in January 2022 and in the Journal of the American Medical Association in October 2022.
Previous report
ECOSPOR IV was an open-label single-arm study evaluating SER-109 in 263 adult subjects with recurrent CDI. The overall safety profile observed in ECOSPOR IV through 24 weeks indicated that SER-109 was well tolerated, consistent with the safety profile observed in the prior completed Phase 3 study, ECOSPOR III. The ECOSPOR IV study results contributed to the SER-109 safety database and supported product approval. These data were published in the JAMA Network Openin February 2023.
Previous report
Study cohort 1, which included 13 participants who received any dosing of the SER-155 regimen, with 11 of these subjects subsequently receiving an allo-HSCT, nine of whom had evaluable samples for microbiome analysis, was designed to assess safety and drug pharmacology, including the engraftment of drug bacteria in the gastrointestinal tract. In May 2023, we announced the Phase 1b cohort 1 results, including gastrointestinal microbiome data (drug pharmacology) from the first 100 days from the nine subjects who had evaluable samples for microbiome analysis. This analysis showed the successful engraftment of SER-155 bacterial strains, and a substantial reduction in the cumulative incidence of pathogen domination (a biomarker associated with the risk of serious enteric infections, and resulting bloodstream infections, as well as GvHD) as compared to a reference cohort of patients in this patient population. The tolerability profile observed was favorable, with no serious adverse events attributed to SER-155 administration. Stem cell engraftment was observed in all subjects.
Previous report
In April 2024, we announced completion of enrollment in study cohort 2, which includes 45 participants. Study cohort 2 incorporates a randomized, double-blinded placebo-controlled design to further evaluate safety, engraftment, and incidence of gastrointestinal ESKAPE microbiome pathogen domination, as well as the incidence of enteric infections, enteric driven blood stream infections, and GvHD. Cohort 2 subjects are administered either SER-155 or placebo at a 1:1 ratio. The study is being conducted at a number of leading cancer centers across the U.S. The cohort 2 data readout is anticipated in September 2024.

Following the Closing, we expect to focus on advancing SER-155 and our other wholly-owned cultivated live biotherapeutic candidates to improve patient outcomes for medically vulnerable patient populations with potential to address large commercial opportunities. We are designing live biotherapeutics optimized to prevent the colonization and overgrowth of pathogens in the gastrointestinal tract and modulate host function to increase epithelium integrity and to induce immune tolerance. We believe clinical and nonclinical data across our programs support the development of live biotherapeutics to target the prevention and treatment of a broad swath of infections, and in inflammatory and immune diseases. We believe that the scientific and clinical data from our SER-109 program validate this novel therapeutic approach in the context of infection. We believe this approach may be replicable across different bacterial pathogens to develop live biotherapeutics with the potential to protect a range of medically compromised patients from infections, including pathogens that harbor antimicrobial resistance, or AMR.
Current wording
Our live biotherapeutic candidates are consortia of bacteria designed to optimize specific, targeted pharmacological properties, and are formulated for oral delivery. We maintain a differentiated live biotherapeutics drug discovery and development platform that includes good manufacturing practices, or GMP, manufacturing capabilities for this novel drug modality. We are designing live biotherapeutic candidates optimized to prevent the colonization and overgrowth of pathogens in the gastrointestinal tract and modulate host function to increase epithelium integrity and to induce immune tolerance. We believe clinical and nonclinical data across our programs support the development of live biotherapeutics to target the prevention and treatment of a broad swath of infections, and in inflammatory and immune diseases. We believe that the scientific and clinical data from the development of VOWST (our then product candidate SER-109 program) and the data from the SER-155 Phase 1b study validate this novel therapeutic approach in the context of infection. We believe this approach may be replicable across different bacterial pathogens to develop live biotherapeutics with the potential to protect a range of medically compromised patients from infections, including pathogens that harbor AMR.
Previous wording
We have progressed additional preclinical stage programs to evaluate whether live biotherapeutics may reduce the incidence of infection in indications such as chronic liver disease, cancer neutropenia, solid organ transplant, and antimicrobial resistant, or AMR, infections more broadly in high-risk settings such as intensive care units, or ICUs, and long term acute care facilities, or LTACs. Additional efforts in the early-stage portfolio are focused on the SER-301 program in inflammatory bowel disease, or IBD, and programmatic objectives that are supported through a partnership with the Crohn’s and Colitis Foundation, or CCF. These efforts aim to (i) confirm the functional phenotype and inflammatory state of patient subpopulations observed in our prior ulcerative colitis, or UC clinical trials, and (ii) prioritize inflammatory targets and evaluate the potential to utilize biomarker-based patient selection and stratification for future studies. In addition, we continue to leverage microbiome pharmacokinetic and pharmacodynamic data from across our clinical and preclinical portfolios, using our reverse translational development platform to prioritize future drug targets and to identify opportunities for combination therapies across various indications, including inflammatory and immune diseases, cancer, and metabolic diseases.
Current wording
In addition to allo-HSCT, we intend to evaluate SER-155 and other cultivated live biotherapeutic candidates in other medically vulnerable patient populations including autologous-HSCT patients, cancer patients with neutropenia, chimeric antigen receptors therapy, or CAR-T, recipients, individuals with chronic liver disease, solid organ transplant recipients, as well as patients in the intensive care unit and long-term acute care facilities.

As of June 30, 2024, we had cash and cash equivalents totaling $71.2 million. Based on our currently available cash resources, our future operating plans, and the capital expected to be obtained from the Transaction, if consummated, and considering our ongoing obligations related to the Transaction, we anticipate being able to extend our cash runway into the fourth quarter of 2025, subject to material compliance with the TSA (as defined below), to be entered into at Closing between us and SPN. Absent the Transaction, our currently available cash resources will fund our operations into the fourth quarter of 2024. In accordance with applicable accounting standards, we evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within 12 months after the date of the issuance of the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. In performing this analysis, we excluded certain elements of our operating plan that cannot be considered probable of occurring. Under the applicable accounting standards, the receipt of potential funding from the Transaction, which is subject to stockholder approval, and any future equity issuances cannot be considered probable, as these events are outside our control. Accordingly, management has concluded that substantial doubt exists about the our ability to continue as a going concern for 12 months from the date the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q, are issued. See “Risk Factors— Risks Related to Our Financial Position and Need for Additional Capital —We have identified conditions and events that raise substantial doubt regarding our ability to continue as a going concern.”

We believe that the scientific and clinical data from our SER-109 program validate our novel approach of using live biotherapeutics to decolonize pathogens, resulting in reduced rate of infections in medically compromised patients. Data from the SER-109 ECOSPOR III and ECOSPOR IV Phase 3 trial published in the New England Journal of Medicine (Feuerstadt et al., 2022) and Journal of the American Medical Association (Sims et al., 2023) suggest that live biotherapeutics have the potential to restructure the gut microbiome and shift the gut metabolic landscape. Additional data show that SER-109 rapidly reduced the abundance of bacteria associated with common antibiotic resistance genes, or ARGs, and reduced ARG abundance in the gut (Straub et al., 2023). Collectively, we believe these data suggest the potential for live biotherapeutics to prevent the colonization and overgrowth of pathogens that can establish in the gut and ultimately to reduce infections. We believe reducing the risk of infection may be replicable in a range of medically compromised patients, protecting them from infections seeded by the gut microbiome and resulting downstream clinical sequelae. We believe this approach may also enable us to reduce antimicrobial resistant infections, or AMR, which the World Health Organization declared as a top ten global public health threat facing humanity, and with estimates that yearly deaths may reach 10 million by 2050, putting mortality due to AMR on par with deaths due to cancer.

We are evaluating SER-155, an oral, live biotherapeutic product candidate, consisting of a consortium of cultivated bacteria, in a Phase 1b study in allo-HSCT recipients in an effort to reduce incidences of gastrointestinal-derived infections, and resulting bloodstream infections and GvHD. SER-155 was designed using our reverse translational development platform. The bacteria consortia is designed to optimize: (i) the prevention of the growth of various Enterococcaceae and Enterobacteriaceae species known to potentially dominate the GI and lead to downstream negative clinical outcomes in medically compromised patients and that can harbor antibacterial resistance, (ii) the production of multiple bacterial metabolites that can promote mucosal and epithelial barrier integrity with the goal of reducing the likelihood of harmful bacteria translocating from the gut to the bloodstream through a compromised epithelium, and (iii) the production of multiple bacterial metabolites that can modulate immune pathways to induce immune tolerance with a potential impact on GvHD. The rationale for this program is based in part on published clinical evidence from our collaborators at Memorial Sloan Kettering Cancer Center showing that allo-HSCT patients with decreased diversity of commensal microbes and pathogen domination in the gastrointestinal tract were significantly more likely to die due to infection and/or lethal GvHD (Peled et al., 2020). In December 2023, we received Fast Track Designation for SER-155 to reduce the risk of infection and GvHD in allo-HSCT patients.
Current wording
We are developing SER-155, an investigational, oral, live biotherapeutic designed to decolonize GI pathogens, improve epithelial barrier integrity, and induce immune tolerance to prevent bacterial bloodstream infections, or BSIs, and AMR infections as well as other pathogen associated negative clinical outcomes in patients undergoing allo-HSCT. SER-155 contains 16 bacterial strains selected using our reverse translation discovery and development platform technologies to optimize SER-155’s functional profile. The design incorporates biomarker data from human clinical data and screening data from nonclinical human cell-based assays and in vivo disease models. The bacteria consortia is designed to optimize: (i) the prevention of the growth of various Enterococcaceae and Enterobacteriaceae species known to potentially dominate the GI and lead to downstream negative clinical outcomes in medically compromised patients and that can harbor antibacterial resistance, (ii) the production of multiple bacterial metabolites that can promote mucosal and epithelial barrier integrity with the goal of reducing the likelihood of harmful bacteria translocating from the gut to the bloodstream through a compromised epithelium, and (iii) the production of multiple bacterial metabolites that can modulate immune pathways to induce immune tolerance with a potential impact on GvHD.
Previous wording
We are currently evaluating SER-155 in a Phase 1b study in patients undergoing allogeneic hematopoietic stem cell transplantation, or allo-HSCT, to prevent enteric-derived infections and resulting blood stream infections, as well as induce immune tolerance responses to reduce the incidence of graft-versus-host disease, or GvHD. There are an estimated 40,000 allo-HSCT procedures annually worldwide, and infection is one of the most common causes of mortality in these patients. The Center for International Blood & Marrow Transplant Research, or CIBMTR, reports that 19-28% of deaths in allo-HSCT patients over 18 years of age within 100 days post-transplant are caused by infections and 5-14% by GvHD. In December 2023, we received Fast Track Designation for SER-155 to reduce the risk of infection and GvHD in patients undergoing allo-HSCT.
Current wording
The rationale for this program is based in part on published clinical evidence from our collaborators at Memorial Sloan Kettering Cancer Center showing that allo-HSCT patients with decreased diversity of commensal microbes and pathogen domination in the gastrointestinal tract were significantly more likely to die due to infection and/or lethal GvHD (Peled et al., 2020). There are an estimated 40,000 allo-HSCT procedures annually worldwide, and infection is one of the most common causes of mortality in these patients.

Previous wording
We believe the available study data from cohort 1 suggest that SER-155 administration results in significantly lower incidence rates of gastrointestinal dominations with pathogens of clinical concern, such as Enterococcaceae, Enterobacteriaceae, Streptococcaceae, and Staphylococcaceae. If positive, we further believe the resulting cohort 2 data, together with the cohort 1 SER-155 Phase 1b study results will provide encouraging evidence to support further development of SER-155 to potentially reduce enteric-derived infections, resulting bloodstream infections, and GvHD in individuals undergoing allo-HSCT for cancers and other serious conditions.

We are advancing the SER-147 program, an oral, live biotherapeutic product candidate, consisting of a consortium of cultivated bacteria in development for the prevention of gut-seeded infections and associated downstream blood stream infections in chronic liver disease, or CLD, and other diseases, and spontaneous bacterial peritonitis infections in patients with CLD. SER-147 was designed and optimized using our reverse translational therapeutics development platform. CLD is a progressive condition marked by deterioration of liver function and is reaching epidemic proportions affecting nearly 1.7 billion people worldwide, causing substantial health burden on afflicted countries (GBD 2017 Cirrhosis Collaborators, 2020, Clinical Liver Disease, 2021). In the advanced stages of CLD, known as decompensated cirrhosis, patients exhibit significant immune dysfunction, microbiome disruption, and increased contact with the healthcare system, all of which drive increased susceptibility to bacterial infections (Bajaj et al., 2021, Albillos et al., 2022).
Current wording
We continue to develop another proprietary live biotherapeutic composition, SER-147, designed to prevent bacterial bloodstream, AMR and spontaneous bacterial peritonitis, or SBP, infections in patients with metabolic disease, including chronic liver disease, or CLD. SER-147 was designed and optimized using our reverse translational therapeutics development platform. CLD is a progressive condition marked by deterioration of liver function and is reaching epidemic proportions affecting nearly 1.7 billion people worldwide, causing substantial health burden on afflicted countries (GBD 2017 Cirrhosis Collaborators, 2020, Clinical Liver Disease, 2021).

Our primary focus of research and development since inception has been on our reverse translational platform and the subsequent development of our product and product candidates. Our direct research and development expenses are tracked on a program-by-program basis and consist primarily of external costs, such as fees paid to investigators, consultants, CROs in connection with our preclinical studies and clinical trials, lab supplies and consumables, and regulatory fees. We do not allocate employee-related costs and other indirect costs to specific research and development programs because these costs are deployed across multiple product programs under development.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We anticipate an overall decrease in research and development expenses in 2024 as compared to the prior year, as the restructuring plan implemented in 2023 significantly reduced research and development activities other than the completion of the SER-155 Phase 1b study. Research and development expenses may increase in the future if and as we resume development of any clinical or preclinical programs using proceeds from the Transaction with Nestlé, if consummated.
