Positron, iThemba LABS Enter Into Radioisotope Supply Agreement

August 9, 2013 — Positron Corporation entered into a multi-year radioisotope supply agreement with iThemba LABS of Cape Town, South Africa. The supply agreement contracts the procurement of raw material, strontium-82 (Sr-82) from iThemba LABS for further production of the active pharmaceutical ingredient (API) at Positron's radioisotope production facility in Lubbock, Texas. In September 2013, Positron will receive relevant volumes of strontium-82 for qualification and will commence with commercial availability beginning in February 2014. This additional supply will enhance the industry's strontium-82 supply and increase the availability of radiopharmaceuticals to the end user. Positron intends to make this Sr-82 API supply available to all rubidium-82 generator producers in the marketplace.

The iThemba Laboratory for Accelerator-Based Sciences (LABS) is a group of multi-disciplinary research laboratories administered by the National Research Foundation of South Africa. The iThemba LABS facility provides basic and applied research using particle beams, particle radiotherapy for the treatment of cancer and the supply of accelerator-produced radioactive isotopes for nuclear medicine and research. The Radionuclide Production Department has been producing radiopharmaceuticals and radionuclides for the past 23 years, some of them include 67Ga-citrate, 123I-products, 18F-FDG, 68Ge/68Ga generators, 22Na UHV positron sources and 82Sr (irradiated Rb or RbCl targets). iThemba LABS is the largest facility of its kind in the Southern Hemisphere and one of six facilities in the world that can produce Sr-82 with a proton accelerator.
