This patent contains broad claims covering the use of these proprietary splicing payloads with state-of-the-art ADC linkers and may be used to target different proteins on the cancer cell.<\/p>\n<p align=\"justify\">Akari\u2019s growing pipeline of novel ADCs including AKTX-101 (targeting TROP2 directed) and AKTX-102 (targeting CEACAM5) all use the PH1 payload that is built around this novel IP. Targeting RNA splicing biology has the potential to be a highly effective and differentiated strategy to attack cancer tumors in multiple ways by eliminating vital proteins needed for cancer cell survival, as well as uniquely activating the immune system to drive durable efficacy.<\/p>\n<p align=\"justify\">\u201cThis patent acceptance strengthens the foundation of our proprietary payload platform and reinforces our ability to build a differentiated ADC pipeline,\u201d said Abizer Gaslightwala, President and Chief Executive Officer of Akari Therapeutics. \u201cOur RNA splicing payload enable us to build a novel class of ADC therapeutics that have the potential to disrupt the current ADC category, and we believe expanding broad composition-of-matter protection globally is critical to unlocking multiple ADCs across tumor types and major markets around the world. This patent grant continues to increase the total value of\u00a0Akari\u2019s novel ADC technology, while enabling us to advance the development of cancer therapies for patients across the world while protecting our intellectual property.\u201d<\/p>\n<p align=\"justify\">This Australian patent approval builds on Akari\u2019s expanding global intellectual property portfolio, which includes issued patents in the United States, China, India, Japan, Israel, and Mexico, further strengthening protection of its proprietary PH1 payload platform and reinforcing the Company\u2019s strategy to establish broad, global composition-of-matter coverage.<\/p>\n<p align=\"justify\">Akari\u2019s lead program, AKTX-101, a TROP2-targeting ADC powered by its proprietary PH1 payload, is currently in IND-enabling studies with a targeted Phase 1 first-in-human clinical trial expected in late 2026\/ early 2027. This enables Akari to continue to advance its novel ADC into a rapidly evolving TROP2 ADC class expected to reach ~$12B by 2033<sup>1<\/sup>.<\/p>\n<p align=\"justify\">This patent approval further strengthens Akari\u2019s intellectual property across payload chemistry, ADC architecture, and therapeutic applications, supporting the Company\u2019s strategy to advance a durable and differentiated platform for next-generation ADC development.<\/p>\n<p align=\"justify\">\u00b9 DataIntelo, <em>TROP2-Targeted Therapies Market Report<\/em>, 2026<\/p>\n<p align=\"justify\">\n        <strong>About Akari Therapeutics <\/strong>\n      <\/p>\n<p align=\"justify\">Akari Therapeutics is an oncology biotechnology company developing next-generation antibody drug conjugates (ADCs) with a unique payload, PH1, which targets RNA splicing. Utilizing its innovative ADC discovery platform, the Company has the ability to generate ADC candidates and optimize them based on the desired application to any antigen target of interest. Akari\u2019s lead candidate, AKTX-101, targets the Trop2 receptor on cancer cells with a proprietary linker, enabling it to deliver its novel PH1 payload directly into the tumor with minimal off-target effects. Unlike current ADCs that use microtubule inhibitors and DNA-damaging agents as their payloads, PH1 is a novel payload that is a spliceosome modulator designed to disrupt RNA splicing within cancer cells. This splicing modulation has been shown in preclinical animal models to induce cancer cell death while activating both the innate and adaptive immune systems to drive robust and durable activity. In preclinical studies, AKTX-101 has been shown to have significant activity and prolonged survival relative to ADCs with traditional payloads. Additionally, AKTX-101 has the potential to be synergistic with checkpoint inhibitors and has demonstrated prolonged survival as both a single agent and in combination with checkpoint inhibitors. The PH1 payload has also been demonstrated to be very active against cancer cells with key oncogenic drivers such as KRAS, BRAF, ARV7, FGFR3 fusions, and others. The Company has initiated IND enabling studies for AKTX-101 with a goal of starting its First-In-Human trial by late 2026\/early 2027. Akari is also developing AKTX-102, an ADC candidate targeting CEACAM5 (Carcinoembryonic Antigen-related Cell Adhesion Molecule-5), a well-validated tumor antigen broadly expressed across multiple solid tumors. AKTX-102 is designed to leverage Akari\u2019s proprietary PH1 spliceosome-modulating payload and a novel antibody construct to enable differentiated tumor cell killing and immune activation.<\/p>\n<p align=\"justify\">For more information about the Company, please visit <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=H_YU5f7CFugq1LJyNCVC9ueQBXCdc0UMaz9SJxxW9Cqn7LrwKIapBpgmuil03OH37lRpgTcx7AUnfTgPTZlYR5zQKcxmMiRUyTJqzB3fiHA=\" rel=\"nofollow\" target=\"_blank\">www.akaritx.com<\/a> and connect on <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=_WVR8KrT9pi5DOq_smFGafsSABC6XPBQ6zN1RmHSx_Mtx-zQq8u7vGSUDLk7cY9XXmbbAb3F7tZP2oaaeqPpkw==\" rel=\"nofollow\" target=\"_blank\">X<\/a> and <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=c_BoDDqtDQkp2AHD4oGaw5_vMuH6LY3HbyiQg09mw_b6Vgi9wgTZ01xw9Pwxv_FgKz3Z0WuwGEDgvug1dJC7vD2vZNqivCpl8lEFq0ZUOb8=\" rel=\"nofollow\" target=\"_blank\">LinkedIn<\/a>.<\/p>\n<p>\n        <strong>Cautionary Note Regarding Forward-Looking Statements<\/strong>\n      <\/p>\n<p align=\"justify\">This press release includes express or implied forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, about the Company that involve risks and uncertainties relating to future events and the future performance of the Company.
