Ardena Oss

About This Facility

Welcome to Ardena Oss

Ardena operates two facilities in Oss, Netherlands. Our Pivot Park site covers drug substance development and manufacturing, solid state research, and bioanalysis. Our Kloosterstraat site is a purpose-built 2,200 m² nanomedicine facility, constructed to GMP Annex 1 standards with advanced cleanrooms, integrated development and analytical labs, and dedicated warehousing. Two sites, one integrated team — combining the scientific depth your molecule needs across chemistry, solid state, bioanalysis, and nanomedicine under one coordinated program.

Ardena Somerset

About This Facility

Welcome to Ardena Somerset

Ardena Somerset is our US center of science and manufacturing – and it does more than most CDMO sites its size. The facility houses 200+ scientists, engineers, and operations specialists serving as a Center of Excellence for advanced oral dosage forms, including hot melt extrusion and solubility enhancement for poorly soluble drugs. FDA registered, DEA licensed, and cGMP compliant, it supports late-stage and small-scale commercial manufacturing for controlled substances and complex molecules.

In April 2026, Ardena opened a new state-of-the-art bioanalytical laboratory at Somerset — 2,500+ sq ft of operational lab space with LC-MS/MS systems, immunochemistry platforms, and controlled sample storage. The lab supports quantitative analysis for preclinical and clinical studies across small molecules, biologics, ADCs, and biomarker programs, bringing Ardena’s European bioanalytical depth directly to North American clients. Additional platforms including qPCR and flow cytometry are being added in the coming months.

Two capabilities. One site. Coordinated by scientists who own innovation.
