Immutep Quarterly Activities Report Q4 FY23 - Seite 4

IMP761 DEVELOPMENT PROGRAM FOR AUTOIMMUNE DISEASE
In May, Immutep appointed a clinical research organisation to conduct its GLP toxicology study evaluating the safety and toxicity of IMP761, Immutep's proprietary preclinical candidate and the world’s first LAG-3 agonist for autoimmune diseases. This study is a key step before the commencement of first-in-human trials to treat the underlying cause of multiple autoimmune diseases.

INTELLECTUAL PROPERTY
Immutep was granted three patents during the quarter. A new patent was granted by the US Patent Office protecting Immutep’s intellectual property for treating cancer by administering efti and a PD-1 pathway inhibitor, specifically BMS-936559, durvalumab, atezolizumab or avelumab.

The US Patent Office also granted a new patent for composition-of-matter claims covering Immutep’s pre-clinical immunosuppressive product candidate, IMP761, which is designed to target the root cause of autoimmune diseases by directly silencing self-antigen-specific effector T cells.

Finally, the Japan Patent Office granted a new patent protecting Immutep’s intellectual property for a potency assay for release testing of efti which is used in the commercial-scale (2,000L) manufacturing process for efti. This new Japanese patent follows the grant of a similar patents in Australia and South Korea in 2023 and 2022 respectively.
