Leaders In Industrial
Operations And Product Supply

Grounded in excellence and driven by innovation, our Industrial Operations and
Product Supply (IOPS) team is responsible for the production of Regeneron products.

IOPS successfully manufactures a range of biopharmaceuticals for patients worldwide, including our approved therapeutic proteins and those involved in clinical studies.

Our operations follow strict adherence to current Good Manufacturing Practice (cGMP) and use cutting-edge analytical equipment, automated laboratory information management systems and electronic document management systems, all of which are supported by an extensive calibration, validation and preventive maintenance programme. Our independent clean-room suites with ultra-modern clean utilities support both single-use and stainless steel cell culture bioreactors, as well as large-scale chromatography systems designed to produce and purify our product candidates.

Regeneron behind the scenes

Supported by a highly skilled team of professionals, our integrated teams bring an unsurpassed expertise in developing, operating, optimising, validating and licensing the complex manufacturing processes required for production of biopharmaceuticals.

Take a behind the scenes look at how we produce the highest-quality medicines for patients as efficiently as possible.

“We manufacture our drug product to the
highest possible standards and treat
each
medicine as if it could be used by a
member of our own family.”

Production

Cells continue to grow for a specified amount of time in the controlled bioreactor environment to produce an optimal amount of the target protein.

Harvest

The harvesting process separates protein and media from cellular debris, first through centrifugation and then by a sequence of increasingly fine filters.

The target protein is isolated, purified and concentrated. The target protein is isolated, purified and concentrated.
Purification

The target protein is isolated, purified and concentrated in a multi-step process to ensure it is of the highest quality.

Buffers are added to maintain the therapeutic protein at a desired concentration. Product is dispensed into containers to ensure stability through the entirety of the drug’s shelf life.
Formulation & dispensing

Buffers are added to maintain the therapeutic protein at a desired concentration. Then, product is dispensed into containers to ensure stability through the entirety of the drug’s shelf life.

The formulated drug is labeled and packaged for distribution. The formulated drug substance is filled into the appropriate vials or syringes.
Filling, packaging & labeling

From IOPS, the formulated drug substance is filled into the appropriate vials or syringes, labeled and packaged for distribution.
