Akeso Launches First Bispecific ADC, Strengthening Its Leadership in Cancer Therapies

Akeso's Groundbreaking Step in Cancer Treatment

On July 3, 2025, Akeso, Inc. (9926.HK), a pivotal player in oncology, proudly announced the successful enrollment of its first patient in the Phase Ia clinical trial for AK146D1, a novel bispecific Antibody-Drug Conjugate (ADC) targeting Trop2 and Nectin4. With regulatory approvals in hand from respected authorities such as the U.S. FDA, Australia's TGA, and China's NMPA, the company is poised to venture deeper into the realm of improved cancer therapies.

What Sets AK146D1 Apart?

AK146D1 represents a significant milestone for Akeso as it is the company’s inaugural bispecific ADC to enter clinical pathways. This comes on the heels of Akeso’s achievements with its first-in-class bispecific antibodies, cadonilimab (PD-1/CTLA-4) and ivonescimab (PD-1/VEGF), both of which have previously secured approval in China. Akeso currently holds an unmatched position as the only company worldwide with two approved cancer immunotherapy bispecific antibodies. This strong foundation enables the company to confidently advance its 'IO+ADC' 2.0 strategy, which is revolutionizing treatment paradigms in oncology.

The Importance of IO+ADC Strategy

The IO+ADC strategy plays a crucial role by integrating immune-oncology approaches with innovative ADC therapies. By leveraging ADC technologies, Akeso aims to reshape the global landscape of cancer treatments and set new benchmarks in oncology care. As stated by Dr. Yu Xia, Akeso’s visionary founder and CEO, the development of such groundbreaking therapies signifies the company's commitment to unlocking new potentials within its innovative product portfolio, thus driving the evolution of cancer therapies further into the future.

Targeting Trop2 and Nectin4: A Promising Approach

Targets like Trop2 and Nectin4 are intricately expressed in diverse tumor types while maintaining lower expression levels in normal tissues. This characteristic makes them optimal targets for ADC therapy. The dual targeting approach of AK146D1 aims to broaden the therapeutic window and tackle the challenge of resistance often associated with single-target ADCs, potentially enhancing treatment efficacy for patients.

A Unique Innovation in Bispecific ADCs

Although there exist approved monoclonal ADCs that target Trop2 and Nectin4, AK146D1 stands out as the pioneering bispecific ADC that strategically targets both markers. Early preclinical studies indicate that AK146D1 is demonstrating remarkable anti-tumor activities accompanied by favorable safety profiles in tumors exhibiting the expression of Trop2 or Nectin4. This groundbreaking development marks a significant step toward enhancing treatment outcomes for cancer patients, and Akeso is optimistic about the positive impact it could haveon the global clinical landscape.

Conclusion: The Future of Cancer Treatment

As Akeso moves forward with the development of AK146D1, the company is excited about this opportunity to not only redefine therapy standards but also to significantly benefit clinicians and patients globally. The implications are vast: with a strong foundation in bispecific antibody innovation, Akeso aims to continue its leadership role in the biopharmaceutical sector, particularly within the ADC landscape. With the advancement of next-generation treatments, Akeso is committed to the ongoing fight against cancer, offering hope and improved outcomes for patients worldwide.

This initiative represents more than just the launch of a clinical trial; it's a beacon of progress in the relentless pursuit of cutting-edge cancer therapies.
