Helsinn Advanced Synthesis opens its largest dedicated Anticancer bay

Biasca, Switzerland, July 30, 2020 – Helsinn, a Swiss pharmaceutical group focused on building quality cancer care and rare disease products, announces that its manufacturing subsidiary, Helsinn Advanced Synthesis SA (HAS), which develops and manufactures Active Pharmaceutical Ingredients (APIs), cGMP Advanced Intermediates, High Potency APIs (HPAPIs) and anticancer compounds, has opened its largest dedicated Anticancer bay at its manufacturing plant in Biasca, Switzerland. The new Anticancer bay will be used for the development, analysis, and manufacturing of clinical and commercial anticancer APIs.

In 2012, HAS built its first dedicated Anticancer plant that could manufacture compounds with an OEL down to 50 ng/m³ and had a small, medium and large-scale bay. Due to the success of this Anticancer plant, in 2016 a new expansion was proposed to build a larger scale bay. After receiving positive results from a feasibility study, a detailed engineering plan was put together in 2017 while procurement began. The project spanned three years and involved more than 100 external suppliers, resulting in the largest Anticancer bay at HAS.

The new bay includes three reactor units: 800 L Hastelloy; 1000 L glass lined; and 1200 L Hastelloy allowing for production scale up to ~50 kg; a conic reactor (150 L capacity) for loading operations in a closed system; one Hastelloy filter dryer (0.5 m² filtering surface); and 1 mill. In addition, there are five glove boxes for product handling in a safe way. The Anticancer facility can handle reaction temperatures from -80°C to +140°C and has a dedicated warehouse.

The Swiss Agency for Therapeutic Products (SwissMedic) inspected the new facility in June 2020 and approved manufacturing to start. The first project was initiated in late June. This new Anticancer bay will allow the Company to continue their innovative and critical work.

Waldo Mossi, Local General Manager, Helsinn Advanced Synthesis S.A., commented: “We are delighted to open our new Anticancer Bay after years of hard work and development. HAS is always looking to stay at the cutting edge of technology and to be able to better serve our clients and their important projects. The new facility will allow us to expand our development, analysis and manufacturing capabilities and will be central to the manufacture and delivery of new anticancer compounds into clinics and then on to patients.”
