Sanofi Expands in China with $130M Deal for Rare Disease Treatment

Sanofi has acquired development and commercialization rights for plozasiran, an RNA-based therapy, in China for $130 million. The deal includes potential milestone payments of $265 million and royalties on future sales. This strengthens Sanofi's position in China's biopharma market and advances Arrowhead Pharmaceuticals' pipeline. Sanofi's diversified portfolio and stable revenue growth make it a major player in the drug manufacturers industry. However, its mixed financial health indicators, including a low cash ratio and Altman Z-Score, suggest potential liquidity constraints and bankruptcy risk.

Sanofi has secured development and commercialization rights for plozasiran, an RNA-based therapy, in China for $130 million. The deal includes potential milestone payments of up to $265 million and royalties on future sales, strengthening Sanofi's position in China's biopharma market and advancing Arrowhead Pharmaceuticals' pipeline [1].

The agreement, signed between Sanofi and Visirna Therapeutics, a subsidiary of Arrowhead Pharmaceuticals, grants Sanofi exclusive rights to develop and commercialize plozasiran in Greater China. Visirna has successfully completed a Phase 3 clinical trial of plozasiran in China, meeting its primary efficacy endpoint and receiving official acceptance from the National Medical Products Administration (NMPA) for a New Drug Application (NDA) in January 2025 [1].

Plozasiran is designed to reduce the production of apolipoprotein C-III (APOC3), a key regulator of triglyceride metabolism. The therapy has shown promise in clinical studies for familial chylomicronemia syndrome (FCS) and severe hypertriglyceridemia (SHTG), with significant reductions in triglycerides and multiple atherogenic lipoproteins [1].

Sanofi's acquisition of plozasiran rights in China aligns with its strategy to expand its cardiometabolic portfolio and address unmet medical needs. The company's strong presence in China and diversified portfolio contribute to its status as a major player in the drug manufacturers industry. However, mixed financial health indicators, such as a low cash ratio and Altman Z-Score, suggest potential liquidity constraints and bankruptcy risk [1].

Upon closing of the Asset Purchase Agreement, Visirna will receive an upfront payment of $130 million from Sanofi. Further milestone payments of up to $265 million are contingent upon regulatory approvals of plozasiran across various indications in mainland China. Arrowhead is also eligible to receive royalties on net commercial product sales in Greater China [1].

This strategic partnership between Sanofi and Arrowhead Pharmaceuticals underscores the potential of RNA interference (RNAi) therapies in addressing intractable diseases. As plozasiran progresses through regulatory approvals and commercialization, it holds promise for improving the lives of patients with elevated triglycerides in China.
