- Interim results show a 45% ORR, with a higher 50% ORR in patients with high MET gene copy number.
- Breakthrough Therapy Designation granted by NMPA, highlighting the potential of savolitinib in treating MET-amplified gastric cancer.
- Low incidence of severe treatment-related adverse events, with only one patient discontinuing due to adverse effects.
Negative Aspects
- Potential risks and uncertainties associated with clinical trials, including unexpected adverse events or safety issues.

Financial Analyst Perspective
From a financial standpoint, HUTCHMED's progress in the clinical development of savolitinib is a positive indicator of potential future revenue streams. The Breakthrough Therapy Designation could expedite the drug's path to market, potentially enhancing the company's market position in China.
