On May 16, 2022 Elicio Therapeutics, a clinical-stage biotechnology company developing a pipeline of novel immunotherapies for the treatment of cancer and other diseases, reported that it has entered into a clinical supply agreement with Regeneron to evaluate the safety and efficacy of Elicio’s lead asset, ELI-002, an investigational KRAS-targeted cancer vaccine, in combination with Regeneron’s Libtayo (cemiplimab), a fully human monoclonal antibody targeting the immune checkpoint receptor PD-1 on T cells, in patients with KRAS-driven tumors (Press release, Elicio Therapeutics, MAY 16, 2022, View Source [SID1234614734]). The combination therapy will be studied in KRAS-driven tumors including Stage III and IV non-small cell lung cancer (NSCLC), Stage IV colorectal cancer (CRC) and unresectable, locally advanced or oligometastatic pancreatic ductal adenocarcinoma (PDAC). The study, which is expected to begin in 2023, will be conducted by Elicio Therapeutics. Each party will provide their respective agent for the trial. Libtayo is being jointly developed by Regeneron and Sanofi.

"We’re investigating ELI-002’s immune education in combination with the ability of Libtayo to block PD-1 and potentially activate the ELI-002-induced T cells to target cancers. This combination may provide a new treatment option for patients living with these difficult to treat cancers," said Dr. Christopher Haqq, Executive Vice President, Head of Research and Development, and Chief Medical Officer at Elicio. "ELI-002 includes mutated KRAS peptides that are delivered directly to the lymph nodes, ‘the schoolhouse of the immune system.’ The AMP technology allows for ELI-002 to be delivered in high quantities to the lymph nodes and remain there, where it will ‘educate’ the immune cells to target tumor cells for killing."
Dr. Annette Matthies, Chief Business Officer at Elicio, added, "Regeneron is a leading biotech company, and this clinical supply agreement supports the development of our ELI-002 therapeutic cancer vaccine program as well as our AMP platform. With the ongoing Phase 1 trial studying ELI-002 as a monotherapy and this upcoming combination study, we believe that ELI-002 has the potential to make a difference in the often-challenging KRAS space."
About ELI-002
ELI-002 is a structurally novel investigational AMP therapeutic vaccine targeting mutant KRAS-driven cancers. KRAS mutations are among the most prevalent human cancers. KRAS drives 32% of lung cancers, 40% of colorectal cancers and 85% to 90% of pancreatic cancer cases. ELI-002 is comprised of AMP-modified mutant KRAS peptide antigens and ELI-004, an AMP-modified immune-stimulatory oligonucleotide CpG adjuvant. The AMP mKRAS peptides and AMP CpG are targeted to the lymph node where they can potentially enhance the action of key immune cells.
ELI-002 is currently being studied in a Phase 1 trial (AMPLIFY-201) in patients with early-stage KRAS-driven solid tumors, following surgery and chemotherapy. Enrollment in the Phase 1 study continues, following the dosing of the first patient at MD Anderson in October 2021, with the expectation to move from Cohort 2 to Cohort 3 in the next quarter, and the Phase 1b/2 trial planned for early 2023. This trial will study the broad spectrum 7-peptide formulation of ELI-002. This formulation is designed to provide immune response coverage against seven of the most common KRAS mutations, thereby increasing the potential patient population for ELI-002 and potentially reducing the chance of bypass resistance mechanisms.
About the Amphiphile Platform
Our proprietary Amphiphile, or AMP, platform delivers investigational immunotherapeutics directly to the "brain center" of the immune system – the lymph nodes. We believe this site-specific delivery of disease-specific antigens, adjuvants, and other immunomodulators may efficiently educate, activate, and amplify critical immune cells, potentially resulting in induction and persistence of potent adaptive immunity required to treat many diseases. In preclinical models, we have observed lymph node-specific engagement driving therapeutic immune responses of increased magnitude, function, and durability. We believe our AMP lymph node-targeted approach will produce superior clinical benefits compared to immunotherapies that do not engage the lymph nodes.
Our AMP platform, originally developed at the Massachusetts Institute of Technology, or MIT, has broad potential across cancers, infectious diseases, and other disease indications to advance a number of development initiatives through internal activities, in-licensing arrangements or development collaborations and partnerships.
The Amphiphile platform is thought to deliver immunotherapeutics directly to the lymph nodes by latching on to the protein albumin, found in the bloodstream, as it travels to lymphatic tissue. In preclinical models, we have observed lymph node-specific engagement driving therapeutic immune responses of increased magnitude, function, and durability.
