Phase I Study of SYNB1891, an Engineered E. coli Nissle Strain Expressing STING Agonist, with and without Atezolizumab in Advanced Malignancies.
(PubMed, Clin Cancer Res)
- P1 | "In addition, a dose-related increase in serum cytokines was observed, as well as stable disease in 4 participants refractory to prior PD-1/L1 antibodies. Repeat intratumoral injection of SYNB1891 as monotherapy and in combination with atezolizumab was safe and well tolerated, and evidence of STING pathway target engagement was observed."

(Clin Cancer Res)
- P1 | N=70 | NCT04167137 | Sponsor: Synlogic | "Twenty-four participants received monotherapy across six cohorts, and 8 participants received combination therapy in two cohorts. Five cytokine release syndrome events occurred with monotherapy, including one that met the criteria for dose-limiting toxicity at the highest dose; no other SYNB1891-related serious adverse events occurred, and no SYNB1891-related infections were observed. SYNB1891 was not detected in the blood at 6 or 24 hours after the first intratumoral dose or in tumor tissue 7 days following the first dose. Treatment with SYNB1891 resulted in activation of the STING pathway and target engagement as assessed by upregulation of IFN-stimulated genes, chemokines/cytokines, and T-cell response genes in core biopsies obtained predose and 7 days following the third weekly dose."

Synlogic Presents Data from SYNB1891 Phase 1 Trial at American Association for Cancer Research (AACR) Annual Meeting
(PRNewswire)
- P1, N=70; NCT04167137; Sponsor: Synlogic; “Synlogic, Inc…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….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…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.”
