Patrys Limited announced the appointment of Dr. Charmaine Gittleson as the Chairman of the Board of Directors, effective from the conclusion of the Company's Annual General Meeting later on November 16, 2022. Dr. Gittleson is the former Chief Medical Officer of CSL Limited with more than 20 years of experience in pharmaceutical development in Australia and the USA. Dr. Gittleson's expertise spans many aspects of the pharmaceutical industry, from drug development and clinical research through to strategic planning and executive management.

Dr. Gittleson has been involved in drug development programs across a wide range of different therapeutic areas, and has successfully worked with regulators in key markets such as the US, EU, Asia Pacific, Japan and South America. Dr. Gittleson is currently the Chair of Antisense Therapeutics Limited where she has been actively involved in strategy development, capital raising and Board renewal. Dr. Gittleson is joining Patrys at an exciting time in the Company's evolution as it completes the last remaining stages of preclinical development for PAT-DX1 in preparation for its first clinical trial, which is scheduled to commence in the second half of 2023.

In parallel, Patrys is in the process of establishing a commercial-scale production process for its second deoxymab, PAT-DX3, which is a full-sized IgG antibody capable of delivering therapeutic payloads into the nucleus of cancer cells. The Company also advises that, as previously foreshadowed, Mr. Stefan Ross will step down from the Board of Directors at the close of business on November 16, 2022, now that a permanent Chairman has been found. Stefan will remain as Company Secretary, maintaining his seven year affiliation with the Company.
