Keymed Biosciences’ IND Approval for CM518D1: A Breakthrough in China’s Expanding Gastrointestinal Cancer Market

Keymed Biosciences (02162.HK) has taken a significant step forward in its mission to address gastrointestinal cancers with the approval of an Investigational New Drug (IND) application for CM518D1, a novel CDH17-targeted Antibody-Drug Conjugate (ADC). This milestone, granted by China’s National Medical Products Administration (NMPA), positions Keymed at the forefront of a rapidly growing oncology market. With gastrointestinal cancers accounting for over 30% of all cancer-related deaths in China, the commercial success of CM518D1 could unlock substantial value for investors.

The Gastrointestinal Cancer Market: A Golden Opportunity in China

The Chinese oncology market is primed for explosive growth, driven by rising cancer incidence, aging populations, and advancements in precision medicine. By 2028, the China oncology drugs market is projected to reach $42.19 billion, growing at an 8.75% CAGR since 2022. Gastrointestinal cancers—such as gastric, pancreatic, and colorectal cancers—are a major focus within this sector.

Stomach cancer alone, which accounts for over 85% of gastrointestinal oncology drug sales, is expected to hit $892.7 million in 2025, rising to $1.5 billion by 2030 at a 10.5% CAGR. This growth is fueled by both rising disease prevalence and the adoption of advanced therapies like ADCs, which combine targeted delivery with potent cytotoxic agents. Keymed’s CM518D1, designed to bind to the CDH17 protein overexpressed in gastrointestinal tumors, directly addresses this high-demand therapeutic space.

Keymed’s Pipeline: A Portfolio of ADC Innovations

CM518D1 is not Keymed’s only promising asset. The company’s pipeline includes CMG901/AZD0901, a Claudin 18.2 ADC co-developed with AstraZeneca, which is in Phase III trials for second-line gastric cancer. This drug’s progress underscores Keymed’s expertise in ADC development and its ability to leverage partnerships for commercial success.

Strategic Advantages: ADC Expertise and Clinical Momentum

Keymed’s ADC platform is a key differentiator. ADCs, which pair antibodies with chemotherapy drugs, minimize off-target effects and enhance efficacy—a critical advantage in treating heterogeneous gastrointestinal tumors. The company’s focus on rare biomarkers like CDH17 and Claudin 18.2 allows it to target underserved patient populations.

Clinical trials for CM518D1 are expected to leverage data from ongoing studies of CMG901, accelerating timelines. Additionally, China’s regulatory environment, which prioritizes oncology innovation, could fast-track approvals. The NMPA’s IND greenlight for CM518D1 aligns with Healthy China 2030 policies emphasizing domestic drug development.

Risks and Considerations

While the outlook is promising, risks remain. ADC development is complex, with potential safety issues arising from payload toxicity. Competitors like Roche (AVARON, targeting HER2) and Seattle Genetics (PADCEV, targeting Nectin-4) are also advancing ADCs in gastrointestinal cancers. Keymed must demonstrate superior efficacy or a broader patient population to differentiate itself.

Conclusion: A Compelling Investment Thesis

Keymed Biosciences stands at the intersection of a booming oncology market, cutting-edge ADC technology, and strategic regulatory tailwinds. With CM518D1 targeting a $1.5 billion gastric cancer segment and CMG901 nearing pivotal trials, the company is well-positioned to capitalize on China’s $42 billion oncology opportunity by 2028.

Investors should monitor Phase I/II trial results for CM518D1, expected in 2025, as well as commercialization timelines. While competition is stiff, Keymed’s pipeline depth and focus on niche biomarkers suggest it can carve out a significant market share. For those willing to take on developmental risk, Keymed represents a high-reward play in one of Asia’s most dynamic healthcare sectors.
