About BTG Specialty Pharmaceuticals

BTG Specialty Pharmaceuticals is a division of Boston Scientific. We provide rescue medicines typically used in emergency rooms and intensive care units to treat patients for whom there are limited treatment options. 

We are dedicated to delivering quality medicines that make a real difference to patients and their families through the development, manufacture, and commercialisation of pharmaceutical products. Our current portfolio of antidotes counteract certain snake venoms and the toxicity associated with some heart and cancer medications. 

We are actively researching new uses for our products and seek opportunities to license or acquire additional products that enable specialist physicians to serve their patients better.

Our History

BTG has long considered itself a “journey company” and made our mark in the field of medicine in many ways before focusing on rescue medicines.  Click below to learn more about how we became BTG Specialty Pharmaceuticals.

  • In the 1940s the “British Technology Group” was set up by the UK government to commercialise inventions from UK universities and the newly-formed NHS.  BTG was the original “tech transfer office,” helping to commercialise technology ranging from agricultural equipment to mobile phones.  We made notable contributions to the medical field, helping bring to market the MRI, cephalosporin antibiotics, interferon, cholesterol assay tests, and three-part knee replacements among other inventions.

    In 1992 the group was spun out of government and took on the name BTG plc when it was publicly listed in ’95.  Following a strategic review in 2005, BTG plc focused on life sciences and began investing in specialty pharmaceuticals, notably through the acquisition of Protherics, another listed UK company, and establishment of a commercial and medical infrastructure in the US.

    For several years BTG plc focused on minimally invasive procedures growing out of advances in medical imaging technology. We invested in a portfolio of devices to treat patients with cancer, vascular disease, and emphysema. In 2019 BTG plc was acquired by Boston Scientific, a global medical technology leader.

    Today, BTG Specialty Pharmaceuticals is a division of Boston Scientific and reports into Boston Scientific’s corporate global operations group. BTG Specialty Pharmaceuticals operates as a self-sufficient business and is fully resourced to support continued growth and a sustainable future for the business.
