"WuXi XDC is widely recognized as a global leader in ADC innovation, and with this partnership, we believe Akari can rapidly advance and further validate our PH1 payload on AKTX-101 in future clinical studies."</p>  <p align="justify">WuXi XDC's CEO, Jimmy Li, Ph.D., added, "We are pleased to work with Akari to advance the novel PH1 payload into more advanced studies. WuXi XDC has a proven record of advancing novel ADC payloads and strives to remain at the forefront of ADC innovation. We believe we are the trusted and best partner to help Akari advance this first-in-kind RNA splicing modulating ADC payload for its use in its lead program, as well as other future ADC molecules. There is a strong need for ADC payload innovation to improve on current therapies, and WuXi XDC wants to be at the forefront working with partners like Akari to bring novel ADCs to cancer patients."</p>  <p align="justify">Akari's lead program AKTX-101 is initially targeting metastatic urothelial cancer, where there continues to be significant unmet medical need particularly in the second-line treatment setting. Patients with metastatic disease that progress following first-line therapies often have limited options beyond standard chemotherapy, which offers only modest clinical benefit in this setting. The Company believes that AKTX-101 with its novel PH1 payload may provide a promising new therapeutic approach for urothelial cancer patients, while also demonstrating the broader potential of Akari's PH1 payload platform.</p>  <p align="justify">AKTX-101 features Akari's proprietary PH1 payload, a novel spliceosome modulator designed to disrupt RNA splicing in cancer cells. By targeting RNA splicing, PH1 represents a new direction for next-generation ADC therapies. Unlike traditional ADC payloads that are microtubule inhibitors or DNA-damaging agents, PH1 offers a differentiated mechanism of direct cytotoxicity as well as the unique activation of the innate and adaptive immune systems to attack cancer. In preclinical studies, AKTX-101 has demonstrated superior anti-tumor regression and complete remissions relative to other ADCs. Akari believes this differentiated mechanism positions PH1 as part of a new wave of ADC payload innovation aimed at significantly improving the therapeutic potential of antibody-drug conjugates.</p>  <p align="justify">Akari is working to advance its lead program, AKTX-101, into a Phase 1 clinical trial expected to initiate in late 2026 or early 2027 subject to regulatory clearance. This key clinical milestone reinforces Akari's ongoing progress to advance its novel payload and execute its strategy to develop ADC therapies with novel payloads that have the potential to improve outcomes for cancer patients.</p>  <p align="justify"><strong>About WuXi XDC</strong></p>  <p align="justify">WuXi XDC Cayman Inc. (stock code: 2268.HK) is a globally recognized contract research, development, and manufacturing organization (CRDMO) specializing in bioconjugates.

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's 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 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's proprietary PH1 spliceosome-modulating payload and a novel antibody construct to enable differentiated tumor cell killing and immune activation.</p>  <p align="justify">For more information about the Company, please visit <a href="https://www.globenewswire.com/Tracker?data=Rj39fS2SHK3nMfFDwkmI46bUopwu0830dAYvruLLb62w03LcGfmmrC07oEME5ohXt1sbpzPpxER2S8uTl-Tq82h_-91-VcIriho2O-_kEEg=" rel="nofollow" target="_blank">www.akaritx.com</a> and connect on <a href="https://www.globenewswire.com/Tracker?data=lUAFX7DJjNpcOgem-2f87E8VBeR-M4aZxzMoSbvTdmwlVGgUp886AvqBpixjStffW_vfWLlZLP3AxeR8VH_ERA==" rel="nofollow" target="_blank">X</a> and <a href="https://www.globenewswire.com/Tracker?data=MJQWYED3ibHMWFI4CYKZfqVEhGo6IC5Jx8I95UtwFCtBe-tnhwwLL1-kO7wWgczPauVjMySWdv0xEKdgH6-MNDOB7FapGEv42Kh3GNCejr4=" rel="nofollow" target="_blank">LinkedIn</a>.</p>  <p align="justify"><strong>Cautionary Note Regarding Forward-Looking Statements</strong><br></br><br></br>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.
