o A two-part clinical trial for HMPL-A830 in China will study the drug in patients with solid tumours, records on U.S. government registry ClinicalTrials.gov showed.

o Solid tumours are masses of tissue that can be cancer.

o The HUTCHMED subsidiary, HUTCHMED Ltd, is also eligible to receive additional payments tied to development, regulatory and commercial milestones of up to about $1.2 billion.
