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 SYNB1891SYNB1891 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).
