Tempel Lane Fill-Finish Drug-Product Manufacturing Facility

See all projects by Regeneron Pharmaceuticals →

Regeneron Pharmaceuticals' dedicated drug-product fill-finish manufacturing facility at 350 Tempel Lane on Regeneron's second (East Greenbush) campus in Rensselaer County, New York. This is the two-story, 364,110-square-foot drug-manufacturing building — connected to an existing 211,600-square-foot warehouse — that the 2018 Rensselaer County IDA application separately itemized at approximately $188 million and 300 permanent jobs, distinct from the broader mixed-use Tempel Lane build-out. The building provides in-house aseptic formulation, fill-finish and packaging of Regeneron's biologic medicines (including Dupixent and Libtayo), reducing reliance on third-party contract fill-finish. Chronology: publicly announced in September 2018 with the Rensselaer County IDA application filed later that year; construction and build-out followed; New York State Board of Pharmacy manufacturer license 88-M-8754 for 350 Tempel Lane was issued October 11, 2024 during licensing and start-up preparation; Regeneron's own April 22, 2025 manufacturing release still described the new Rensselaer fill/finish facility as under construction. By 2026 the facility is operational and scaling — running aseptic fill/finish for commercial biologics, with active manufacturing hiring and FDA inspection activity through August 2026. AFT records the site as Operational (operational by 2026) but assigns NO exact production-start date: Regeneron has not published a commercial production-start day, and the October 11, 2024 license issuance is retained only as corroborating regulatory evidence — a license-issuance date does not establish that manufacturing began on that day and is not used as the operational date. AFT records only the separately itemized $188 million and 300 permanent jobs. Explicitly excluded to prevent rollup double counting: the broader up-to-$800 million / 1,500-job seven-year Tempel Lane campus build-out, the 240,000-square-foot science/laboratory building, the existing warehouse, the 1,100-space parking garage, office space, the approximately $140 million New York State incentive package and the $15.7 million IDA tax breaks, and Regeneron's 'more than $7 billion' U.S. investment rollup.

Why this project qualifies

With approximately $188 million in facility-specific investment and 300 permanent operating jobs announced, this project clears both of AFT's qualifying thresholds ($100 million in facility-specific investment OR 100 permanent operating jobs). It is also confirmed by official public sources and involves a physical manufacturing facility in the United States.

Why it matters

The pharmaceuticals context.

Pharmaceutical manufacturers are committing billions to new U.S. production capacity for active ingredients, injectable medicines, biologics and other high-demand treatments. North Carolina and Indiana remain major centers of investment, while new facilities are being planned across the South. The current project pipeline includes both large greenfield campuses and major expansions of established production sites.
