cergutuzumab amunaleukin (RG7813) / Roche - LARVOL DELTA

Obinutuzumab Pretreatment as a Novel Approach to Mitigate Formation of Anti-Drug Antibodies Against Cergutuzumab Amunaleukin in Patients with Solid Tumors. (PubMed, Clin Cancer Res) - "These preliminary findings suggest that obinutuzumab pretreatment before CEA-IL2v administration in patients with CEA+ solid tumors may be a feasible and potent ADA mitigation strategy, with an acceptable safety profile, supporting broader investigation of obinutuzumab pretreatment for ADA mitigation in other settings."

A humanized minipig model for the toxicological testing of therapeutic recombinant antibodies. (PubMed, Nat Biomed Eng) - "In line with observations in human patients, the genetically modified minipigs tolerated the clinically non-immunogenic IgG1κ-isotype monoclonal antibodies daratumumab and bevacizumab, and elicited antibodies against the checkpoint inhibitor atezolizumab and the engineered interleukin cergutuzumab amunaleukin. The humanized minipigs can facilitate the safety and efficacy testing of therapeutic antibodies."

A humanized minipig model for the toxicological testing of therapeutic recombinant antibodies (Nature) - "Here we report the generation of Göttingen minipigs carrying a mini-repertoire of human genes for the immunoglobulin heavy chains γ1 and γ4 and the immunoglobulin light chain κ. In line with observations in human patients, the genetically modified minipigs tolerated the clinically non-immunogenic IgG1κ-isotype monoclonal antibodies daratumumab and bevacizumab, and elicited antibodies against the checkpoint inhibitor atezolizumab and the engineered interleukin cergutuzumab amunaleukin. The humanized minipigs can facilitate the safety and efficacy testing of therapeutic antibodies."

89Zr-labeled CEA-targeted IL-2 variant immunocytokine in patients with solid tumors: CEA-mediated tumor accumulation in a dose-dependent manner and role of IL-2 receptor-binding (ESMO 2016) - P1; "CEA-IL2v (cergutuzumab amunaleukin, RG7813) is an engineered IL-2 variant (IL-2v) antibody directed against Carcinoembryonic Antigen (CEA) with abolished IL-2 receptor (IL-2R) &agr; (CD25) binding. At all doses, 89Zr- CEA-IL-2v accumulated in spleen and secondary lymphoid tissues, due to IL-2R mediated uptake. CEA-mediated tumor accumulation was observed in a dose-dependent manner with consistent targeting starting at 20 mg CEA-IL2v; a phase I study as monotherapy and with atezolizumab is ongoing."

A novel PD1-IL2v immunocytokine for preferential cis-activation of IL-2R signaling on PD-1 expressing T cell subsets strongly potentiates anti-tumor T cell activity of PD-1 checkpoint inhibition and IL-2R-beta-gamma agonism (AACR 2019) - "...We have described tumor-targeted CEA-IL2v and FAP-IL2v immunocytokines that are based on an engineered IL2v moiety with abolished binding to IL-2Ra (CD25) to avoid undesired CD25-mediated toxicities and Treg expansion...In summary, our data demonstrate that preferential cis-targeting of IL2v to PD-1+ antigen specific T cells with PD1-IL2v results in a strong potentiation of T cell response and anti-tumor efficacy as compared to the combination of PD-1 checkpoint inhibition with FAP-IL2v. These preclinical data establish PD1-IL2v as a promising next generation IL-2 for cancer immunotherapy."
