Cadonilimab

After its approval for recurrent/metastatic cervical cancer, cadonilimab reached a major milestone in 2024 with the approval for a new indication in first-line gastric cancer, addressing unmet needs in PD-L1 low/negative populations. The sNDA for first-line cervical cancer is currently under review. Cadonilimab is also currently in 8 Phase III trials and nearly 20 Phase II studies, exploring treatments for major cancers in both first- and later-line settings.

Ivonescimab

In 2024, ivonescimab was approved for the treatment of EGFR-TKI-resistant, locally advanced or metastatic non-squamous non-small cell lung cancer (nsq-NSCLC). A major milestone was reached in May 2024 when the Phase III HARMONi-2 trial, comparing ivonescimab to pembrolizumab in first-line PD-L1-positive NSCLC, showed positive results. Data presented at the 2024 World Conference on Lung Cancer (WCLC) revealed a median Progression-Free Survival (mPFS) of 11.14 months for ivonescimab, compared to 5.82 months for pembrolizumab. This breakthrough highlights ivonescimab's potential as a key therapy in next-gen immuno-oncology and boosts its global commercialization prospects.

Currently, ivonescimab is in 12 registrational/Phase III clinical trials, including 6 head-to-head studies against PD-1/L1 therapies, as well as in over 20 Phase II trials.

Key Phase III Trials in NSCLC :

• Ivonescimab monotherapy vs. pembrolizumab as first-line (1L) treatment for PD-L1+ NSCLC
• Ivonescimab + chemotherapy vs. pembrolizumab + chemotherapy (global multicenter trial) as 1L treatment for NSCLC
• Ivonescimab + chemotherapy vs. tislelizumab + chemotherapy as 1L treatment for squamous NSCLC (sq-NSCLC)

Phase III Trials in Other Major IO Indications:

• Ivonescimab + chemotherapy vs. durvalumab + chemotherapy as 1L treatment for biliary tract cancer
• Ivonescimab + AK117 (CD47 mAb) vs. pembrolizumab as 1L treatment for PD-L1+ head and neck squamous cell carcinoma (HNSCC)
• Ivonescimab combination as 1L treatment for triple-negative breast cancer (TNBC)
• Ivonescimab in PD-(L)1-resistant NSCLC, and ivonescimab combination as 1L treatment for pancreatic cancer (preparation/initiation underway)

These trials reflect ivonescimab's development strategy that is based on a fundamental understanding of tumor immunobiology and designing clinical studies that compares it with standard of care, encompassing both first-line and later-line treatments for high-incidence, high-mortality cancers. This positions Akeso as a key innovator in next-generation cancer immunotherapy, improving and contributing to the global IO cancer treatment landscape.

Potential Disclosure of Ivonescimab's Topline HARMONi Clinical Data Mid-Year

International Expansion of Novel Drug Development Accelerates

Akeso's global partner on ivonescimab, Summit Therapeutics, is advancing three international multicenter Phase III clinical trials:

• The HARMONi study, a Phase III clinical trial that evaluates ivonescimab combined with chemotherapy compared to placebo plus chemotherapy in patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who have progressed after treatment with a 3rd generation EGFR TKI (e.g., osimertinib). Summit has announced plans to disclose topline data in mid-2025.
• Summit expanded the HARMONi-3 study cohort in 2024 to include both squamous NSCLC (sq-NSCLC) and non-squamous NSCLC (nsq-NSCLC), expanding first-line coverage for all NSCLC populations.
• The HARMONi-7 study, a global Phase III trial comparing ivonescimab monotherapy with pembrolizumab monotherapy as a first-line treatment for PD-L1-high NSCLC, is expected to begin in 2025.

In February 2025, Summit has entered into a clinical collaboration with Pfizer to evaluate ivonescimab in combination with Pfizer's antibody-drug conjugates (ADCs) across solid tumors. Pfizer will be responsible for conducting the operations of the studies. The studies will be overseen by both Summit and Pfizer. Both parties retain their respective rights to their products. Akeso is responsible for the production of ivonescimab used in the clinical trial conducted globally.

Beyond bispecific antibodies

Akeso is advancing a pipeline of promising candidates beyond bispecific antibodies. The company's first self-developed ADC, AK138D1, with the first patient enrolled in Australia for Phase I.
