The Lexington, MA Controlled Environment Landscape

Rare disease biologics. Nucleic acid therapies.The stakes don't get higher.

Takeda’s Lexington MA biomanufacturing operations produce four commercial biologics for patients with rare diseases — Hunter Syndrome, Fabry Disease, Type 1 Gaucher Disease, and Hereditary Angioedema. These are products for which there are no alternatives. Contamination is not a quality event; it is a patient safety event.

Just down Hayden Avenue, Novo Nordisk occupies 80,000 square feet housing its Global Nucleic Acid Therapies and Advanced Drug Delivery R&D groups, alongside Dicerna Therapeutics. Kiniksa Pharmaceuticals calls Lexington home as well. The sophistication of Lexington’s cleanrooms reflects the sophistication of the molecules manufactured within them. That demands a cleaning partner who understands GMP compliance, disinfection validation, and microbial contamination risk at a fundamental level.

At 45 Hartwell Avenue — the former ThermoFisher Lexington site — United Therapeutics is advancing one of the most consequential manufacturing programs in the corridor: xenotransplantation organ manufacturing, where contamination control isn’t a compliance checkbox but a direct determinant of patient survival. United Therapeutics’ growing Lexington presence represents exactly the caliber of high-stakes, regulator-scrutinized manufacturing environment CleanTech Systems was built to serve.

Why CleanTech Systems

Built for Lexington, MA'scontrolled environments.

GMP-trained for the highest-stakes pharma environments
Our cleanroom cleaning technicians understand what a 483 is, what triggers one, and what prevents one. They are trained in GMP disinfection protocols, microbial contamination risk, validation compliance, and gowning discipline. National janitorial companies train people to clean buildings. We train people to protect manufacturing environments.
Microbial and physical contamination
Both, simultaneously — pharmaceutical and biologics cleanrooms face two distinct contamination threats that must be managed in parallel. Our technicians are educated in both threat vectors and trained to address both in every cleaning cycle.
Your audit calendar is our audit calendar
CleanTech Systems' Site Director for your account knows when your FDA inspection window is, when your internal QA audits are scheduled, and when your environmental monitoring program is active. We don't show up to clean. We show up to protect your compliance record.
