Who Is the Manufacturer of Breyanzi?
Breyanzi (lisocabtagene maraleucel) is manufactured by Bristol Myers Squibb (BMS), a leading global biopharmaceutical company known for its focus on innovative medicines for serious diseases. The story of Breyanzi’s development and eventual commercialization under the BMS brand is a notable example of the complex landscape of modern drug development and corporate consolidation in the life sciences sector.
The therapy was initially developed by Juno Therapeutics, a biotech company that was pioneering cell therapies. Juno was acquired by Celgene, another major pharmaceutical company, for approximately $9 billion in 2018. Not long after, in 2019, Bristol Myers Squibb completed its own acquisition of Celgene for a reported $79 billion, effectively bringing Juno's assets, including the in-development Breyanzi, under the BMS umbrella. This strategic move solidified BMS's position in the lucrative and rapidly growing field of cell therapies, particularly in oncology.
The Highly Specialized Manufacturing Process
Unlike conventional pharmaceuticals, the production of Breyanzi is a highly individualized and complex process that involves using a patient’s own immune cells. The therapy is not manufactured in a single, standard batch, but is instead custom-made for each individual patient. This personalized approach is what makes the treatment so effective against certain lymphomas.
The intricate, multi-step manufacturing process for Breyanzi includes:
- Leukapheresis: A procedure performed at a specialized collection center where a patient’s blood is drawn and their white blood cells, specifically T-cells, are separated out. The rest of the blood is then returned to the patient.
- Transportation: The collected T-cells are then carefully shipped to a designated manufacturing facility operated by Bristol Myers Squibb, such as the sites in Bothell, Washington, and Summit, New Jersey.
- Genetic Engineering: In the laboratory, the patient's T-cells are genetically modified using a viral vector to express a special protein on their surface called a Chimeric Antigen Receptor (CAR). This CAR is designed to specifically recognize and bind to the CD19 protein found on the surface of B-cell cancer cells.
- Cell Expansion: The genetically engineered T-cells, now called CAR T-cells, are multiplied into millions in the lab to create the therapeutic dose. The manufacturing process ensures a defined ratio of CD8+ and CD4+ CAR-positive T-cells to reduce dose variability.
- Quality Control and Freezing: The expanded CAR T-cells undergo rigorous testing to ensure safety, sterility, and efficacy. They are then frozen for storage and shipment.
- Infusion: The final product is shipped back to the treatment center. Prior to infusion, the patient undergoes a short course of chemotherapy (lymphodepletion) to prepare their body. The one-time infusion of Breyanzi is then administered at the certified healthcare facility.
A Comparison of CAR T-Cell Therapy vs. Traditional Chemotherapy
Breyanzi's personalized and complex nature sets it apart from more traditional cancer treatments like chemotherapy. The table below outlines some key differences between these two therapeutic approaches.
| Feature | CAR T-Cell Therapy (Breyanzi) | Traditional Chemotherapy |
|---|---|---|
| Therapeutic Approach | Personalized cell therapy that uses a patient's own immune cells genetically modified to target cancer. | Systemic treatment that uses chemicals to kill rapidly dividing cells, including cancer cells. |
| Treatment Timeline | Involves several weeks for cell collection and manufacturing before a single, one-time infusion. | Typically involves multiple cycles of drug administration over weeks or months. |
| Key Mechanism | Engineered T-cells directly recognize and attack cancer cells expressing a specific target protein (CD19). | Non-specific mechanism; can damage both cancerous and healthy, fast-growing cells throughout the body. |
| Customization | Highly customized and manufactured for each individual patient. | Standardized drug formulation administered to different patients, although dosage may be adjusted. |
| Side Effects | Unique side effects like Cytokine Release Syndrome (CRS) and neurotoxicity, often managed in a hospital setting. | Common side effects include hair loss, nausea, fatigue, and increased risk of infection due to immunosuppression. |
The Broader Impact of Breyanzi
Breyanzi has received multiple approvals from regulatory bodies, including the U.S. Food and Drug Administration (FDA). It is indicated for treating various B-cell lymphomas and leukemias that have relapsed or are refractory to prior lines of treatment. The development of CAR T-cell therapies like Breyanzi represents a significant advancement in oncology, offering a potent and targeted treatment option for patients who have limited alternatives.
As Bristol Myers Squibb continues to research and expand the potential applications of Breyanzi and other cell therapies, the focus remains on navigating the logistical complexities of manufacturing and expanding access to these transformative treatments. The company is committed to advancing this personalized medicine to provide better outcomes for patients with certain blood cancers.

Conclusion
In summary, Bristol Myers Squibb is the manufacturer of Breyanzi, a complex CAR T-cell therapy designed to treat certain relapsed or refractory B-cell malignancies. The therapy’s origin story involves a series of strategic corporate acquisitions, highlighting the evolution of biopharmaceutical innovation. The manufacturing process is a highly personalized endeavor, requiring specialized procedures and a dedicated timeline for each patient. By genetically engineering a patient's own T-cells, Breyanzi offers a targeted and durable treatment option that contrasts significantly with traditional chemotherapy. This personalized approach, while complex, underscores the potential for cell therapy to transform cancer care and provide new hope for patients facing serious diseases.
