Phase Ib/II study of imprime PGG and pembrolizumab in patients with previously treated advanced non-small cell lung cancer (NSCLC): BTCRC LUN 15-017. (PubMed, Transl Lung Cancer Res) - P1/2 | "The combination of imprime and pembrolizumab is tolerable but did not improve the outcome of advanced stage NSCLC patients who previously progressed on anti-programmed death 1 (PD-1)/PD-L1 immunotherapies. Further investigation is needed to understand the effects of therapeutic PAMPs to mount a strong innate immune response against cancer."

Phase 1b study of maintenance soluble beta-glucan (Odetiglucan) in combination with a CD40 agonistic monoclonal antibody (CDX-1140) in patients with metastatic pancreatic adenocarcinoma that had not progressed on first-line chemotherapy (AACRPanCa 2024) - "The combination of odetiglucan and CDX-1140 was feasible and safe when administered as maintenance therapy in patients with mPDAC whose disease had not progressed on 1L chemotherapy. Treatment produced encouraging activity with changes in immunological correlates associated with disease control. These early results support further investigation combining odetiglucan with a CD40 agonist in mPDAC."

Kupffer cells prevent pancreatic ductal adenocarcinoma metastasis to the liver in mice. (PubMed, Nat Commun) - "Here, we show that macrophages respond to β-glucan (odetiglucan) treatment by inhibiting liver metastasis...Furthermore, β-glucan drove T cell activation and macrophage re-polarization in liver metastases in mice and humans and sensitized metastatic lesions to anti-PD1 therapy. These findings demonstrate the significance of macrophage function in metastasis and identify Kupffer cells as a potential therapeutic target against pancreatic cancer metastasis to the liver."

Imprime PGG, a soluble yeast beta-glucan PAMP, converts the immunosuppressive myeloid tumor microenvironment into an immunoactive one: translation of preclinical findings to melanoma and triple-negative breast cancer (TNBC) patients (EORTC-NCI-AACR 2018) - P2; "Background: Imprime PGG (Imprime), an IV administered soluble yeast -1,3/1,6 glucan is being clinically developed in combination with tumor-targeting antibodies, anti-angiogenics, and checkpoint inhibitors (CPI). Collectively, these data show consistency between preclinical and clinical observations that demonstrate that Imprime/Pembro remodels the immunosuppressive myeloid tumor microenvironment and triggers the infiltration and activation of immune cells in preclinical and patient tumors."
