In 2025, Sanofi pursued a series of strategic collaborations, acquisitions, and licensing agreements aimed at strengthening its core franchises, expanding its pipeline, and positioning the company for long-term growth. These deals reflect a targeted approach to innovation, focusing on high-value therapeutic areas such as immunology, oncology, rare diseases, and vaccines.
One of the year’s major moves was the acquisition of Astellas’ rare disease portfolio, which added late-stage and commercial-stage assets in neuromuscular and metabolic disorders. This strengthened Sanofi’s leadership in rare diseases and expanded its pipeline in areas with significant unmet need.
Sanofi also entered a strategic partnership with TScan Therapeutics to co-develop T-cell receptor-based therapies for oncology. This collaboration provides access to innovative immuno-oncology platforms while complementing Sanofi’s existing cancer therapy portfolio, accelerating its presence in next-generation treatments.
In vaccines, Sanofi signed a licensing and collaboration deal with Moderna to co-develop mRNA-based influenza and combination vaccines. This deal positions Sanofi to leverage mRNA technology for faster, more effective vaccine development and broadens its capacity for innovative public health solutions.
Additionally, a strategic alliance with Precision BioSciences focused on genome editing technologies, aiming to advance therapies in immunology and rare diseases. This agreement underscores Sanofi’s commitment to adopting cutting-edge modalities that can transform patient care.
