医药行业周专题：心衰，Pipeline激烈竞争的潜在大市场

Investment Rating - The report maintains a "Positive" investment rating for the pharmaceutical and biotechnology industry in China [2]. Core Insights - The heart failure market presents significant potential, with a focus on improving patient prognosis. In 2017, there were approximately 12.1 million heart failure patients in China, categorized into HFrEF (35.6%), HFmrEF (20.6%), and HFpEF (43.8%) based on LVEF [3][19]. - Treatment for HFrEF has evolved from the "golden triangle" of RASI, BB, and MRA to the "new quadruple therapy" including SGLT2i, which is crucial for improving patient outcomes. The sGC agonist, Vericiguat, is undergoing clinical trials for expanded indications and may become a new first-line option [3][4]. - There is a significant unmet need in the treatment of HFmrEF and HFpEF, with very few drugs showing clear clinical benefits. Currently, only SGLT2i has received an IA level recommendation in guidelines, indicating a lack of available medications [4]. Summary by Sections Heart Failure Market: Large Potential and Core Focus on Prognosis Improvement - Heart failure is characterized by high incidence and mortality rates, with chronic heart failure treatment focusing on symptom relief and reducing mortality and hospitalization risks [3][25]. - The chronic heart failure drug market in China is projected to grow rapidly due to an aging population and the need for long-term medication [5][27]. Unmet Needs and Intense Competition in New Drug Development - Despite advancements in chronic heart failure treatment, the mortality rate remains high, with a 3-year all-cause mortality rate of 28.2% for discharged heart failure patients in China [4][61]. - The global pipeline for chronic heart failure includes nearly 30 candidates in clinical development, with a majority being from overseas companies. Domestic candidates like S086 and recombinant human Neulengrin are in Phase III trials and show promising progress [4][63]. Investment Recommendations and Targets - The chronic heart failure market is characterized by a large patient population requiring long-term medication, and the approval of new mechanism drugs will drive market expansion [5]. - Key companies to watch include Xinlitai and Heng Rui Medicine, as they are involved in the development of promising candidates in the chronic heart failure space [5].
