Akeso’s Lung Cancer Breakthrough: A Strategic Win in China’s Expanding Oncology Market

The National Medical Products Administration (NMPA) of China’s recent approval of Akeso’s ivonescimab (AK-106) for first-line treatment of PD-L1-positive advanced non-small cell lung cancer (NSCLC) marks a pivotal milestone in oncology innovation. This approval, supported by robust Phase III trial data demonstrating superior efficacy over existing therapies, positions ivonescimab as a transformative treatment option in a rapidly growing market.

Efficacy Data: Outperforming PD-1 Inhibitors

The HARMONi-2 trial, pivotal to this approval, showed ivonescimab’s median progression-free survival (PFS) of 11.14 months versus 5.82 months for pembrolizumab, with a hazard ratio (HR) of 0.51—indicating a 49% reduction in disease progression risk. Interim overall survival (OS) data further highlights its potential, with a 22.3% reduction in mortality risk at 39% data maturity. Crucially, this trial represents the first time a therapy has statistically outperformed pembrolizumab in a head-to-head Phase III setting, underscoring ivonescimab’s clinical differentiation.

Beyond NSCLC, ivonescimab’s dual PD-1/VEGF mechanism—targeting both tumor immunity and angiogenesis—has shown efficacy in multiple subtypes, including EGFR-TKI-resistant NSCLC and squamous cell carcinoma. This versatility, combined with a favorable safety profile, positions it as a “chemotherapy-free” first-line option, appealing to patients seeking less toxic regimens.

Market Context: China’s Lung Cancer Growth Engine

China’s NSCLC market is a critical driver of global oncology demand. With over 878,000 new cases projected by 2025 and a 10.4% CAGR, the market is expected to reach $4.3 billion by year-end. This growth is fueled by rising incidence due to smoking, air pollution, and an aging population, alongside accelerated adoption of advanced therapies.

Akeso’s $294 million (RMB 2 billion) 2024 revenue, driven by bispecific antibodies like ivonescimab and cadonilimab, reflects strong commercial traction. The drug’s inclusion in China’s National Reimbursement Drug List (NRDL) in 2024 has further boosted accessibility, ensuring cost-effective treatment for patients.

Strategic Advantages: Global Ambitions and Partnerships

Akeso’s strategy extends beyond China. Its collaboration with Summit Therapeutics aims to expand ivonescimab’s indications globally, including a Phase III trial (HARMONi-7) comparing it to pembrolizumab in PD-L1-high NSCLC. Partnerships with companies like Pfizer—exploring combinations with antibody-drug conjugates (ADCs)—further amplify its therapeutic potential.

The drug’s status as the first globally approved bispecific antibody with dual immuno-angiogenic mechanisms offers a competitive edge. In markets saturated with PD-1 inhibitors, ivonescimab’s superior efficacy and mechanism could displace rivals, particularly in first-line settings where treatment choice directly impacts long-term survival.

Investment Considerations: Growth Metrics and Risks

Investors should monitor global trial outcomes, including the HARMONi-7 data (expected mid-2025), which could unlock approvals in key markets like the U.S. and EU. Additionally, Akeso’s pipeline expansion into indications like diabetic macular edema (DME) and its NRDL inclusion mitigate risks from pricing pressures.

However, challenges remain. Biosimilar competition in PD-1 inhibitors (e.g., bevacizumab) could compress margins, while regulatory hurdles in international markets pose execution risks.

Conclusion: Akeso’s Path to Leadership in Oncology

Akeso’s NMPA approval for ivonescimab is a catalyst for growth in a $4.3 billion NSCLC market with 25.4% CAGR potential in China. Backed by superior clinical data and strategic partnerships, ivonescimab is poised to capture significant market share, especially in first-line PD-L1-positive NSCLC—a segment representing ~30% of NSCLC cases.

With a pipeline spanning 40+ indications and a cost-effective profile via the NRDL, Akeso is well-positioned to capitalize on China’s oncology boom. Global trials and partnerships further amplify its potential, making it a compelling investment in an industry where innovation and accessibility drive long-term value.

In a crowded oncology space, Akeso’s science-driven differentiation and commercial execution make it a standout play for investors seeking exposure to high-growth, life-saving therapies.
