Akeso's Cadonilimab Receives FDA Approval for Phase III Gastric Cancer Trial

Akeso's Cadonilimab: Pioneering Advances in Gastric Cancer Treatment

Akeso, Inc., a prominent biopharmaceutical company based in Hong Kong, has achieved a significant milestone with the FDA's approval to initiate the COMPASSION-37/AK104-311 trial. This pivotal Phase III clinical trial will test cadonilimab, a groundbreaking bispecific antibody targeting PD-1 and CTLA-4, specifically for patients with HER2-negative, unresectable or metastatic gastric adenocarcinoma.

The Trial and Its Importance

The COMPASSION-37 trial marks a critical step in Akeso's global strategy, as it assesses the effectiveness of cadonilimab in conjunction with standard chemotherapy compared to chemotherapy combined with or without nivolumab. This is particularly vital because treatment options for gastric cancer patients are often limited, especially for those classified as PD-L1 low or negative—groups that constitute more than half of gastric cancer patients.

In recent years, the standard treatment for advanced gastric cancer has predominantly involved chemotherapy alongside PD-1 inhibitors like nivolumab. However, this approach has its limitations, particularly for patients with lower PD-L1 expression levels, highlighting the urgent need for alternative therapies. Akeso aims to address this through its dual-track approach combining proprietary development and strategic collaborations to enhance the availability of cadonilimab on a global scale.

Previous Research and Emergent Insights

In 2024, based on the results from the COMPASSION-15 study, cadonilimab was granted approval in China for use in first-line treatment across all PD-L1 expression subgroups, despite the stringent limitations placed on existing PD-1 inhibitors in first-line settings. The COMPASSION-15 trial is unique because it demonstrated significant survival benefits among all patient groups, including those with low or undetectable PD-L1 expressions. This is a groundbreaking achievement in the treatment of advanced gastric cancer.

The trial showed that cadonilimab, in combination with chemotherapy, effectively reduced the risk of death by 39% irrespective of PD-L1 status. In fact, for patients with low PD-L1 expression, there was still a noteworthy 24% reduction in mortality risk compared to the control group.

Addressing Global Challenges in Gastric Cancer Treatment

The mounting challenges surrounding gastric cancer diagnosis and treatment are apparent. Medical guidelines have recently shifted to recommend PD-1 inhibitors only for PD-L1-positive patients, complicating treatment for others. This body of work underlines Akeso's commitment to developing therapies that meet critical needs that current monoclonal antibodies cannot satisfy.

A comprehensive understanding of cadonilimab's mechanisms, tailored particularly for patients who previously had few options, has positioned Akeso at the forefront of next-gen immuno-oncology. This innovative approach not only emphasizes enhanced survival rates but suggests cadonilimab could herald a transformative change in the management of gastric cancer.

Looking Forward: The Future of Cadonilimab

The initiation of the COMPASSION-37 trial is just the beginning. With over 50 assets in its development pipeline, Akeso aims to leverage its advanced research and operational prowess to bring groundbreaking biopharmaceutical innovations to patients worldwide. This rigorous dedication not only underscores Akeso's innovative edge but also emphasizes its commitment to making effective treatments accessible to diverse patient populations.

As the clinical landscape for gastric cancer evolves, the introduction of cadonilimab could very well redefine the standard treatment protocols, potentially transforming outcomes for patients globally.
