With the growing global focus on GLP-1 based therapies, China's role in this field has become increasingly pivotal.

Core Concept: What is Semaglutide API?

Semaglutide API (Semaglutide Active Ingredient) is the biologically active substance that forms the essential core of all semaglutide finished drugs. It can be understood as the "core active component" or "bulk drug substance." Branded drugs (such as the injectables Ozempic®/Wegovy®) are manufactured by combining this high-purity, pharmacopoeia-standard API with pharmaceutical excipients through specific formulation processes. Therefore, the quality, purity, stability, and production process of the API directly determine the safety, efficacy, and consistency of the final drug product.

China: From an API Powerhouse to a Hub of GLP-1 Innovation

China demonstrates formidable strength in the semaglutide and broader GLP-1 arena, showcasing parallel progress in both "R&D innovation" and "advanced manufacturing."

China's biopharmaceutical sector is now a vital source of global innovation in the GLP-1 field. Dozens of GLP-1 receptor agonists (including biosimilars, improved new drugs, and novel dual/multi-target agents based on semaglutide) are currently in clinical development or have already received approval in China. This not only expands treatment options for patients but also signals China's transition from follower to originator in innovation.

In the upstream supply chain, China has established a globally leading cluster for semaglutide API R&D and production. The current landscape and key advantages are evident in:

(1) Technological Mastery and Process Maturity: As a long-chain peptide, semaglutide presents significant technical barriers for large-scale chemical or fermentation synthesis. Leading Chinese API manufacturers have successfully mastered the core technologies for large-scale, high-purity production, enabling stable commercial supply from gram to kilogram scale.

(2) Cost and Scale Advantages: Leveraging a complete chemical industry chain, advanced manufacturing facilities, and significant economies of scale, Chinese suppliers can provide high-cost-performance APIs with international competitiveness, forming a stable and crucial link in the global supply chain.

(3) Stringent Quality and Compliance Systems: Leading Chinese API producers operate in facilities that comply with international cGMP (current Good Manufacturing Practice) standards. Their products meet stringent pharmacopoeial requirements (e.g., purity typically ≥99%, single unknown impurity <0.1%) for markets like the US, EU, and China.

(4) Supply Chain Security and Flexibility: In the context of global supply chain restructuring, Chinese API suppliers provide vital diversification. Many companies (such as SINOWAY INDUSTRIAL CO., LTD.) offer customization services, including specific specifications, dosage form support, flexible packaging, and open client audits, enhancing supply chain resilience and development efficiency for partners.

3. Clear Division of Labor: API Suppliers vs. Branded Drug Holders

A clear distinction must be made between different roles in the value chain:

(1) Semaglutide API Manufacturers: As mentioned, China is home to several companies capable of commercially supplying high-quality semaglutide API, making them core players in the global bulk drug market.

(2) Branded Finished Drug Manufacturer: The Danish pharmaceutical company Novo Nordisk remains the global marketing authorization holder and commercial operator of the specific branded formulations Wegovy®, Ozempic®, and Rybelsus®, which are protected by relevant patents.
