Large-scale, reliable and independent 212Pb production capacity
212Pb is a radioactive element from the decay chain of thorium-232, a radioisotope that occurs naturally on Earth. From the Orano group’s former activities, Orano Med has 22,000 drums of purified thorium-232 at its disposal, a sufficiently plentiful stock of raw materials to cover global needs for Targeted Alpha Therapy.
Moreover, after initial extraction of the daughter elements it contains, the thorium-232 is retained. Given this radioisotope’s extremely long half-life (14 billion years), it will produce descendants again, allowing 212Pb to be extracted again a few years later. Every drum can thus be re-used indefinitely to produce 212Pb.
The patented, entirely chemical process , developed by Orano Med consists of several successive steps of extraction and purification of descendants of thorium-232: radium-228, thorium-228, radium-224 and finally lead-212. Not having recourse to either nuclear reactors or particle accelerators, the chain for the production of 212Pb and the drugs is fully integrated within Orano Med and is independent of external radionuclide suppliers.
Facilities that are unique in the world
In order to produce 212Pb-conjugated drugs and distribute them, Orano Med has developed a global industrial platform.
In France at Bessines-sur-Gartempe in the Haute-Vienne, the Laboratoire Maurice Tubiana (LMT) is implementing the upstream phase of the process: the production of radium-228 and thorium-228 from which the doses of 212Pb will be extracted. It can also call upon the support of its associated research and development center (Centre de Recherche et Développement – CRD). Orano Med is thus continuously optimizing its processes to be better and better at meeting the challenges of industrialization, quality, and protection of the environment, as well as the specific demands of its partners. A larger facility is being planned for the future to industrialize this process and cover global needs in the drug commercialization phase.
The Laboratoire Maurice Tubiana can also produce 212Pb for clinical trials in Europe.
