TAMPA, Fla. and LONDON, July 22, 2026 (GLOBE NEWSWIRE) -- Akari Therapeutics, Plc (Nasdaq: AKTX), an oncology biotechnology company developing antibody drug conjugates (ADCs) with novel RNA splicing modulator payloads, today that announced that its CEO, Abizer Gaslightwala, participated in a Virtual Investor "What This Means" interview focused on the Company'srecently announced strategic research collaboration with Whitehawk Therapeutics.

During the interview, Mr. Gaslightwala discussed the significance of the collaboration and how it represents an important opportunity to evaluate Akari's proprietary PH1 spliceosome modulating payload technology in combination with Whitehawk's topoisomerase I inhibitor (TOP1i) ADC platform. The planned preclinical studies are designed to assess dual payload synergy and generate data that could support future development opportunities for next generation ADCs.

Mr. Gaslightwala also highlighted the increasing industry focus on differentiated ADC payload technologies, noting that recent strategic transactions continue to underscore the growing value being placed on novel payload innovation. He discussed why Akari believes its proprietary PH1 platform is well positioned to contribute to the next generation of ADC development by expanding beyond conventional payload approaches.

"Our collaboration with Whitehawk represents an important step in demonstrating the broader potential of our PH1 payload technology," said Abizer Gaslightwala, Director, President and Chief Executive Officer of Akari Therapeutics. "As the ADC field continues to evolve and industry interest shifts toward differentiated payload innovation, we believe Akari is uniquely positioned to help shape the next generation of ADCs through our novel spliceosome modulating platform and strategic collaborations such as this one."

The discussion also explored the scientific rationale for combining differentiated ADC payload technologies, how dual payload approaches may expand therapeutic opportunities beyond traditional single payload ADCs, and why management believes collaborations such as Whitehawk further validate the broad applicability of Akari's PH1 platform across future oncology programs.

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’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 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 mid-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.
