Synlogic Presents Data from SYNB1891 Phase 1 Trial at American Association for Cancer Research (AACR) Annual Meeting



- Data demonstrates activation of STING pathway in patients -

- Combination arm of Phase 1 study of SYNB1891 ongoing -

CAMBRIDGE, Mass., April 10, 2021 /PRNewswire/ -- Synlogic, Inc. (Nasdaq: SYBX), a clinical stage company bringing the transformative potential of synthetic biology to medicine, today presented data on SYNB1891 for the treatment of solid tumors and lymphoma during the American Association for Cancer Research (AACR) annual meeting, April 10-15, 2021.

The presentation, "Intratumoral injection of SYNB1891, a Synthetic Biotic designed to activate the innate immune system, demonstrates target engagement in humans including intratumoral STING activation," was delivered by Dr. Filip Janku, Associate Professor, Department of Investigational Cancer Therapeutics, Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center. The presentation recording will be available throughout the duration of the conference.

SYNB1891 is an investigational drug being evaluated in an ongoing Phase 1 clinical trial for the treatment of solid tumors and lymphoma. SYNB1891 is composed of an engineered Synthetic Biotic strain of E. coli Nissle that produces cyclic di-AMP (CDA), a stimulator of the STING (STimulator of INterferon Genes) pathway. This mechanism can play a critical role in the initiation of an anti-tumor immune response via activation of APCs and presentation of tumor antigens. Findings from the monotherapy cohorts include:

  • SYNB1891 is safe and well-tolerated as an intratumoral injection in a heterogenous population. 
    • No dose limiting toxicities or SYNB1891-related infections
  • Dose levels through 1e7 live cells demonstrate target engagement as assessed by dose-dependent increases in serum cytokines, upregulation of ISGs and presence of tumor infiltrating lymphocytes.
  • Evidence of durable stable disease was seen in 2 patients and was associated with upregulation genes tied to immune activation and increased intratumoral lymphocytes.

These data support continued dose escalation in the monotherapy and combination arms. The combination arm of the study combines escalating dose levels of SYNB1891 with a fixed dose of a PD-L1 checkpoint inhibitor antibody to establish a recommended Phase 2 dose for the combination regimen.

Data from both arms will continue to be reported over the course of 2021, with mature combination therapy data expected by the end of the year.

About SYNB1891
SYNB1891 is an investigational drug for the intra-tumoral treatment of solid tumors and lymphoma, composed of an engineered Synthetic Biotic strain of E. coli Nissle that produces cyclic di-AMP (CDA), a stimulator of the STING (STimulator of INterferon Genes) pathway. This mechanism can play a critical role in the initiation of an anti-tumor immune response via activation of APCs and presentation of tumor antigens. The bacterial chassis of SYNB1891 also stimulates the innate immune system by several other mechanisms, including via Toll-like receptors (TLRs), potentially adding to the magnitude of the overall immune response. While SYNB1891 has been engineered with safety features that are designed to prevent its replication unless supplemented with specific nutrients, the bacteria remain active for several days within the injected tumor to stimulate a local immune response. SYNB1891 is being evaluated in a Phase 1 clinical trial (NCT04167137).

Exhibit 99.2

Synlogic Presents Data Demonstrating Activity of a Solid Oral Formulation of SYNB1618 at American College of Medical Genetics (ACMG) Annual Meeting



- SYNB1618 demonstrates proof of mechanism and phenylalanine (Phe) consumption in GI tract of healthy volunteers -

- SYNB1618 Phase 2 study in patients with PKU ongoing -

CAMBRIDGE, Mass., April 13, 2021 Synlogic, Inc. (Nasdaq: SYBX), a clinical stage company bringing the transformative potential of synthetic biology to medicine, today presented data from the Phase 1 study of SYNB1618 for the treatment of Phenylketonuria (PKU) during the American College of Medical Genetics (ACMG) annual meeting, being held virtually April 13-16, 2021.

The poster presentation, "Randomized, Placebo-Controlled Study of Lyophilized Formulation of SYNB1618 in Healthy Adult Volunteers," was delivered by Dr. Marja Puurunen, Synlogic's Senior Medical Director. The presentation recording will be available throughout the duration of the conference.

PKU is an inherited metabolic disease that manifests at birth and is marked by an inability to break down phenylalanine, an amino acid that is commonly found in many foods. Left untreated, PKU can lead to serious neurological and neuropsychological problems.

SYNB1618 is an oral investigational Synthetic Biotic medicine designed to break down phenylalanine in the GI tract as a potential treatment for patients with PKU. A solid oral lyophilized powder formulation was evaluated in a Phase 1 study in healthy volunteers. In this study, the safety, tolerability and pharmacodynamics of multiple doses of SYNB1618 were assessed. Findings reported today include:

  • The solid oral formulation of SYNB1618 was well tolerated and metabolically active in the human GI tract.
  • SYNB1618 reduced the increase of plasma D5-Phe following an oral dose of the tracer in a dose-dependent manner in healthy volunteers.
  • SYNB1618 demonstrated evidence of activity in the fasted state i.e. without protein intake, suggesting an ability to metabolize non-dietary Phe in the GI tract.

These data support the further clinical development of this therapy for the treatment of PKU. SYNB1618 continues to advance in a proof of concept Phase 2 clinical trial in adults with PKU, SynPheny, with data expected in the second half of 2021.

About PKU
Phenylketonuria (PKU) is an inherited metabolic disease that manifests at birth and is marked by an inability to break down phenylalanine (Phe), an amino acid that is commonly found in many foods. Left untreated, high levels of Phe become toxic and can lead to serious neurological and neuropsychological problems affecting the way a person thinks, feels, and acts. Due to the seriousness of these symptoms, infants are screened at birth in many countries to ensure early diagnosis and treatment to avoid intellectual disability and other complications.

About SYNB1618
SYNB1618 is an investigational oral drug for the treatment of Phenylketonuria (PKU) composed of an engineered Synthetic Biotic designed to lower plasma phenylalanine (Phe) levels by consuming Phe in the GI tract. A solid oral lyophilized formulation of SYNB1618 was found to be safe and well-tolerated, and consumes Phe in the GI tract of healthy volunteers. Synlogic has initiated a Phase 2 study in PKU patients (NCT04534842).
