Entering into Collaboration Agreement with Immutep Ltd. for the supply of Eftilagimod Alpha
- Eftilagimod Alpha (LAG-3Ig, efti or IMP321), developed by Immutep Ltd., is a soluble recombinant protein consisting of LAG-3 (Lymphocyte Activation Gene 3) and the Fc tail of a human IgG, and activates APCs (Antigen Presenting Cells) such as DCs (Dendritic Cells) through binding to HLA (Human Leucocyte Antigen) Class II molecule.
- Under the supply and collaboration agreement, efti will be supplied as a component of Cytlimic’s proprietary combination adjuvant (with Poly-ICLC (Hiltonol®)) used in its peptide vaccines including CYT001 (antigen protein: HSP70 and GPC3).
- Pre-clinical and clinical studies have shown that the combination of efti and Poly-ICLC (Hiltonol®) synergistically activates antigen-specific CTL (Cytotoxic T Lymphocyte) reactions, and furthermore the combination synergistically suppresses the expressions of major exhaustion markers of these cells (the combination is Cytlimic’s intellectual property).
- “We are very excited to be working alongside Cytlimic to help evaluate efti as part of an innovative cancer vaccine that has potential as a new therapy. Efti is generating interest from around the world and following the agreements with Cytlimic, it is now being evaluated as part of three different combination therapy types: as a cancer vaccine-immunotherapy, as a chemo-immunotherapy and as an immuno-immunotherapy, showing its broad therapeutic potential,”, said Marc Voigt, CEO of Immutep.
- Dr. Shun Doi, Cytlimic’s President and CEO said, “We are delighted with the engagement with Immutep, which will strongly help realize an innovative cancer vaccine-immunotherapy. Our own studies have shown that the combination of LAG-3Ig and Poly IC synergistically boost the efficacy of peptide vaccine, and thus I believe the combination of efti in our vaccine CYT001, which is also unique as an application of artificial intelligence, is an important step to add a new solution in cancer immunotherapy world.”
