CEACAM5 is expressed in 80–90% of gastrointestinal cancers, including colorectal and pancreatic cancer, approximately 30% of bladder cancers, 25% of lung adenocarcinomas, and up to 50% of luminal A (HR+) breast cancers. Importantly, CEACAM5 expression has also been linked to aggressive genetic subtypes, including KRAS-mutated lung cancers, underscoring its relevance across multiple high-unmet-need solid tumor indications.

AKTX-102 is a first-in-class ADC that combines a novel CEACAM5-targeting antibody construct with Akari’s proprietary PH1 spliceosome-modulating payload, designed to deliver potent, differentiated tumor cell killing while simultaneously activating both the innate and adaptive immune responses to the tumor.

Abizer Gaslightwala, President and Chief Executive Officer of Akari Therapeutics, commented, "This patent filing marks another important step in expanding Akari’s differentiated ADC platform and rapidly growing pipeline. AKTX-102 builds on our deep and unique insights into CEACAM5 tumor biology and we believe demonstrates the versatility of our PH1 payload and our antibody expertise to unlock previously intractable targets. We believe PH1 can serve as the foundation for a pipeline of novel ADCs, and this program highlights our innovation on novel payloads for ADCs as well as with tumor antigen biology and antibody engineering to build best-in-class ADCs."

"With AKTX-102, we aim to improve cytotoxic efficacy while harnessing PH1’s unique properties, including innate and adaptive immune activation and activity against KRAS-mutated cancers. We look forward to sharing additional progress as we continue to advance this exciting program," added Mr. Gaslightwala.

Rapidly Expanding and Deepening Patent Estate Around Novel ADCs and Payload Innovation

This newly filed patent further accelerates Akari’s rapid build-out of a broad and defensible intellectual property portfolio spanning payload biology, ADC architecture, and combination strategies. While Akari’s 2025 patent filings (US63/882,631, US63/891,856, and US63/891,861) focused on novel mechanisms of action, payload-driven biology, and ADC combination approaches, this new filing extends protection to a previously undisclosed pipeline asset, AKTX-102, and introduces new composition-of-matter claims around novel antibody design and ADC constructs utilizing this antibody design.

These filings build upon Akari’s foundational PH1 payload patent family (PCT/US2018/051721) and its lead clinical program AKTX-101 (PCT/US2024/024997), collectively creating a layered and rapidly expanding patent moat around next-generation ADCs. Together, Akari expects this growing estate positions the Company to generate multiple first- and best-in-class ADC candidates across a wide range of validated cancer targets.

Cracking One of Oncology’s Toughest Targets

CEACAM5 has long been viewed as a high-value oncology target, but its unique and challenging biology—including extensive antigen shedding and the presence of both soluble and tumor-bound forms—has historically limited therapeutic success. Despite decades of effort, no CEACAM5-directed therapy has yet achieved regulatory approval, whether as a naked antibody, ADC, or T-cell engager.

Beyond its role in tumor growth and metastasis, CEACAM5 also functions as an immunosuppressive checkpoint, inhibiting T-cell and natural killer (NK) cell activity to promote immune evasion. Akari’s newly filed patent covers novel antibody constructs engineered to address these biological challenges, as well as ADCs that pair these antibodies with the Company’s PH1 payload, enabling a differentiated therapeutic approach utilizing PH1’s unique immuno-oncology and cytotoxic modes of action.

This broad composition-of-matter protection provides Akari with ownership over a unique strategy to effectively target CEACAM5 as a best-in-class ADC therapeutic.

Execution, Momentum and Path to the Clinical Stage with Lead Program AKTX-101

As previously announced, Akari continues to execute on its strategy of advancing AKTX-101, its lead Trop2-targeted ADC, toward IND/CTA submission and first-in-human clinical evaluation, while simultaneously expanding a pipeline of next-generation ADCs enabled by its proprietary PH1 payload. With multiple validated targets, a growing IP estate, and a differentiated biological approach, the Company believes it is well positioned to deliver meaningful clinical impact and long-term value creation.

On January 26, 2026 Cogent Biosciences, Inc. (Nasdaq: COGT), a biotechnology company focused on developing precision therapies for genetically defined diseases, reported that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation (BTD) for bezuclastinib in combination with sunitinib for patients with Gastrointestinal Stromal Tumors (GIST) who have received prior treatment with imatinib.

"We are excited to announce this Breakthrough Therapy Designation which recognizes the potential for the bezuclastinib combination to substantially improve upon the currently available treatment options for patients with imatinib-resistant GIST," said Andrew Robbins, Cogent’s President and Chief Executive Officer. "We look forward to the continued collaboration with the FDA as we work to bring the first new treatment option in over twenty years to this patient population."

This Breakthrough Therapy Designation is based on results from the PEAK trial which demonstrated a substantial and highly statistically significant clinical benefit on the primary endpoint of progression free survival (PFS), reducing risk of disease progression or death compared to the current standard of care by 50% (hazard ratio of 0.50, 95% CI: 0.39 – 0.65). mPFS, as assessed by blinded independent central review, was 16.5 months for the bezuclastinib combination vs. 9.2 months for sunitinib monotherapy. The combination was well tolerated, and no new safety risks were observed when compared to the known safety profile of sunitinib. Breakthrough Therapy Designation is intended to expedite the review of medicines that treat a serious or life-threatening condition and have shown clinical evidence indicating the potential for substantial improvement over available therapies.

Earlier this month, the FDA agreed to accept Cogent’s NDA under the FDA’s Real-Time Oncology Review (RTOR) program which allows an applicant to pre-submit components of its NDA to allow the FDA to review clinical trial data before the complete filing is submitted and aims to provide a more efficient review process to ensure safe and effective treatments are available to patients as early as possible.

Cogent plans to present full results from the PEAK trial at a major medical meeting during the first half of 2026. Additionally, in mid-2026 Cogent expects to initiate a Phase 2 trial investigating the benefit of the bezuclastinib plus sunitinib combination for first-line GIST patients with exon 9 mutations who are naive to, or recently initiated treatment with, imatinib.

In addition to the first site being activated, the study has already successfully randomised its first patient, marking a strong start to recruitment.

About the VIGOR Study
The VIGOR trial aims to determine whether vorasidenib, an oral brain-penetrant inhibitor of mutant IDH1/2 enzymes, can improve progression-free survival (PFS) compared to placebo, in patients who have completed standard chemoradiotherapy. This approach builds on promising results from the INDIGO trial, which demonstrated significant benefits in delaying disease progression in IDH-mutant gliomas. VIGOR adopts a rigorous design to validate these findings in a broader setting.

It is a Phase III study that is randomised, placebo-controlled, and triple-blind, intending to involve around 470 patients across multiple international sites. The primary endpoint focuses on progression-free survival (PFS) assessed using the RANO 2.0 criteria, while secondary endpoints include overall survival (OS), time to next intervention, safety and adverse events, and health-related quality of life measures, ensuring a comprehensive evaluation of the treatment’s impact.

The VIGOR trial is coordinated by Dr. Matthias Preusser (Medical University of Vienna, Austria) and co-coordinated by Dr. Marjolein Geurts (Erasmus MC Cancer Institute, Rotterdam, The Netherlands).

Dr. Preusser says:

"The VIGOR trial has the potential to define a new standard of care for patients with IDH-mutant gliomas and will provide valuable new insights and opportunities for further research to improve the diagnostic and therapeutic possibilities for this disease".

Dr. Geurts:

"The randomization of the first patient in the VIGOR study is an exciting and important milestone for patients with IDH-mutant astrocytoma. It reflects the strong collaboration and shared commitment to improving outcomes and expanding treatment options early in the disease course. We are very much looking forward to the next milestones as we work together to make a real difference for patients and their families"

Why this study matters
Patients with IDH-mutant astrocytoma typically experience long survival but face inevitable recurrence. VIGOR seeks to establish whether maintenance therapy can extend the time before progression and reduce the need for subsequent interventions, improving long-term outcomes and quality of life.

The activation of the first site, and the successful randomisation of the first patient, represent early and encouraging milestones in this international effort. Recruitment will expand across more than 50 leading cancer centres in Europe and beyond, with EORTC coordinating the study, in collaboration with the Canadian Cancer Trials Group (CCTG) and the Cooperative Trials Group for Neuro-Oncology (COGNO).
