Elicio Therapeutics and Moffitt Collaborate to Study AMP-CD19 in Combination with CD19 CAR T Cells

CAMBRIDGE, MA, USA I September 17, 2020 I Elicio Therapeutics, a next generation immuno-oncology company, today announced that it has established a collaboration with the Moffitt Cancer Center to characterize combination therapies pairing Elicio’s CD19 Amphiphile and a universal FITC Amphiphile with CD19 CAR T cells. The research will be led by Marco Davila, M.D., Ph.D. associate member of the Blood and Marrow Transplant and Cellular Immunotherapies Department and Medical Director of Cell Therapies at Moffitt.

“Despite high initial response rates, patients with B-cell malignancies have limited durable long-term disease control,” said Christopher Haqq, M.D., Ph.D., Elicio’s Executive Vice President, Head of Research and Development, and Chief Medical Officer. “We are excited to work with Dr. Davila, a pioneer and expert in cell therapy for hematologic malignancies, to study the pharmacology of the combination of AMP-CD19 with CD19 CAR T cells. Dr. Davila’s laboratory is uniquely positioned to evaluate lymph node targeted immunotherapy, since his team evaluates CD19+ malignancies in mice with a normal immune system and normal lymph nodes, a great advantage over more common mouse models conducted in immunosuppressed mice. Positive results would set the stage for clinical trials combining AMP-CD19 with marketed CD19 CAR T cells to increase response rate and durability.”

“Our research, as well as research by other groups, suggest one avenue for improving outcomes for lymphoma patients treated with gene-engineered T cells is to combine this therapy with other agents to enhance response. We believe the highly novel AMP vaccine holds great promise as a combination to increase the efficacy of T cells targeted to B cell malignancies and look forward to developing and evaluating this therapy at Moffitt,” said Dr. Davila.

The AMP-CD19 is a CAR binding peptide modified to traffic into lymph nodes for display on native immune cells. AMP-CD19 can activate engineered T cells, enhance their persistence, and proliferation, as well as enhance their activity in treatment of B-cell malignancies including diffuse large B cell lymphoma (DLBCL) and acute lymphocytic leukemia (ALL).

The AMP modification reprograms the biodistribution of peptides by the addition of an albumin binding and cell membrane insertion domain, which results in improved trafficking into lymph nodes where dendritic cells take in the peptides and present them to the CAR T receptors on the surface of T cells.

Elicio is broadly developing AMP technologies, with ELI-002 targeting solid tumors with mutated KRAS in oncology, the universal adjuvant ELI-004 (AMP-CpG) enhancing efficacy across oncology and infectious disease applications, and discovery programs identifying solid tumor AMP CAR T combinations. In addition, the combination of both Elicio’s Amphiphiles (AMPs) with CAR Ts led to synergy that enhanced solid tumor CAR T therapy in mice (Ma et al., 2019; Singh et al., 2019).

About Elicio Therapeutics

Elicio Therapeutics is advancing the Amphiphile technology across immunotherapy platforms to defeat cancers and infectious diseases. By combining expertise in materials science, immunology, and immuno-oncology, Elicio is engineering potent Amphiphile immunotherapies that precisely target and fully engage the lymph nodes, the site in our bodies where the immune response is orchestrated. Elicio is engineering lymph node targeted cell therapy activators, immunomodulators, adjuvants and vaccines for an array of aggressive cancers and infectious diseases. Elicio’s lead Amphiphile vaccine targeting KRAS-driven cancers will begin initial patient studies in solid tumor patients in 2020. The Amphiphile platform emerged from laboratories of Darrell Irvine, Howard Hughes Investigator and Professor of Biomedical Engineering in the Koch Institute of Integrative Cancer Research at MIT.
