Lonza Group Ltd. Awarded “Potent Compound Safety Certification” for Manufacturing Antibody Drug Conjugates

Basel, 02 April 2009 – Lonza’s facility for antibody drug conjugates (ADC) in Visp, Switzerland, was recently certified by SafeBridge® Consultants as competent and proficient in the safe handling of highly potent active pharmaceutical ingredients (HPAPIs). The new state-of-the-art plant, which came on stream in 2008, is the first in continental Europe to meet the criteria established under the SafeBridge® program for “Potent Compound Safety Certification.”

“The SafeBridge® certification shows our advanced capabilities and experience in safely and effectively producing antibody drug conjugates”, said Uwe H. Böhlke, Head of Lonza Exclusive Synthesis. “As a leader in both antibody production and advanced chemical synthesis, we are uniquely positioned to deliver the highest level of quality in this challenging new field of pharmaceuticals.”

Lonza’s experience with antibody drug conjugates goes back to early 2006. Today, the custom manufacturer has the expertise, procedures and equipment to produce conjugates in milligram to multiple kilogram quantities per batch for both clinical and commercial supply. Additionally, Lonza offers a complete set of process development, analytical, optimization and regulatory support services.

To certify the plant, SafeBridge® conducted a 60-element review of programs, procedures, containment and control of the active pharmaceutical ingredients at each ADC workplace. Based on the quantitative results of the Potent Compound Safety Certification program, SafeBridge® has deemed that Lonza meets current industry standards in the safe handling of ADCs. The SafeBridge® Potent Compound Safety Certification applies to Lonza’s ADC manufacturing and process development facilities, operations and dedicated quality control laboratories.
