From ViroPharma to Takeda: The Corporate Evolution of Cinryze
Cinryze ($C1$ esterase inhibitor [human]) is a specialized medication used for the prophylactic treatment of hereditary angioedema (HAE), a rare genetic disease. While the name Takeda Pharmaceuticals is currently associated with its manufacture, the drug's corporate lineage is a compelling story of acquisition and consolidation within the biopharmaceutical sector. The journey of Cinryze began with ViroPharma Biologics and progressed through Shire before reaching its final destination with Takeda.
The Origins of Cinryze with ViroPharma
ViroPharma Incorporated, including ViroPharma Biologics LLC, was the original developer and commercializer of Cinryze in the early 2000s. The company focused on developing and commercializing innovative products for rare diseases, and Cinryze was a key asset in this mission. The U.S. Food and Drug Administration (FDA) first approved Cinryze in October 2008 for routine prophylaxis in adolescent and adult patients with HAE. The medication is derived from human plasma, and its manufacturing process includes steps like pasteurization and nanofiltration to minimize the risk of transmitting infectious agents. Cinryze was the first C1 esterase inhibitor approved in the U.S. for prophylactic use.
Shire's Acquisition and Portfolio Expansion
Shire, a global biopharmaceutical company specializing in rare diseases, acquired ViroPharma, bringing Cinryze into its portfolio. Under Shire, Cinryze continued its market growth, and the company took steps to strengthen the supply chain. In 2018, the FDA approved the technology transfer of Cinryze manufacturing to Shire's Vienna site, creating a second production source to meet demand and address previous manufacturing interruptions. Shire also expanded the drug's label, with the FDA approving its use for pediatric patients aged 6 and older in June 2018.
The Final Shift to Takeda Pharmaceuticals
Takeda Pharmaceutical Company Limited acquired Shire in a major deal completed in 2019. This acquisition made Takeda a larger pharmaceutical company with a strong rare disease focus. Consequently, Cinryze became part of Takeda's portfolio. Currently, Takeda Pharmaceuticals U.S.A., Inc. and Takeda Manufacturing Austria AG are responsible for manufacturing and marketing Cinryze. Takeda also manages patient support programs for Cinryze, offering resources for individuals with HAE.

The Pharmacology of Cinryze and its Role in HAE Treatment
Cinryze is a human plasma-derived C1 esterase inhibitor (C1-INH). HAE is a genetic disorder caused by a deficiency in the C1-INH protein, leading to excess bradykinin and recurrent swelling. These attacks can affect various body parts, including the face, limbs, gastrointestinal tract, and larynx. Cinryze replaces the missing or non-functional C1-INH protein to regulate the pathways causing swelling. It is primarily used for routine prophylaxis to prevent HAE attacks, distinguishing it from treatments for acute attacks like Firazyr, also a former Shire product.
The Importance of Manufacturer Continuity
Reliable medication supply is crucial for patients with chronic conditions like HAE. The history of Cinryze shows that manufacturer changes can lead to supply disruptions, as seen during an interruption under Shire. Takeda's use of multiple manufacturing sites aims to ensure a stable supply for patients. Managing the transition between companies is vital for seamless patient care, covering production, distribution, and support services.
A Broader Look at Takeda's Rare Disease Commitment
Takeda's acquisition of Shire strategically strengthened its position in rare diseases, covering immunology, hematology, and other genetic conditions. This commitment provides Cinryze with access to Takeda's resources and expertise for research, development, and patient advocacy. Takeda's patient support programs for Cinryze, assisting with administration and access, demonstrate this commitment.
Conclusion
In summary, the answer to who makes Cinryze? is Takeda Pharmaceuticals, but this represents the latest step in the drug's history, which began with ViroPharma and included a period under Shire. This journey reflects the dynamic nature of the pharmaceutical industry and the consolidation of companies specializing in rare diseases. For HAE patients, Takeda's role as the current manufacturer is the most recent chapter in ensuring access to this important prophylactic treatment, highlighting the ongoing importance of reliable supply chains and patient support.
