Core clinical assets are advancing, further developing HBM's product portfolio and pipeline
Since 2021, China's healthcare reform has been further deepened, and reform of the pharmaceutical industry has gradually matured amidst policy and market changes. Adjustments made to the medical insurance catalog, price negotiation of medical insurance and a new round of volume procurement bring continuous challenges to drug pricing, especially pricing of products with weak differentiators. At the same time, the exploration of medical insurance reform has pushed the industry to pay more attention to drug pricing. The Company is committed to bringing benefits and value to patients, and value-based healthcare approach is adopted in its unique and differentiated portfolio planning as well as the clinical assets' development.
