QSAM Biosciences, Inc. is developing nuclear medicines for the treatment of cancer and related diseases. The Company’s technology, CycloSam (Samarium-153 DOTMP), is a clinical-stage bone targeting radiopharmaceutical developed by IsoTherapeutics Group, LLC. Iso Therapeutics Group LLC also developed a commercial radiopharmaceutical on the market, Quadramet (Samarium-153 EDTMP), which is indicated for pain palliation. CycloSam consists of a combination of the radioactive isotope Samarium-153 with a chelating agent, DOTMP (1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetramethylenephosphonic acid). Its combination delivers a radioactive dose to sites of bone mineral turnover, such as bone cancers and tumors. CycloSam has a physical half-life of approximately 46 hours and emits both medium-energy beta particles, which produce the therapeutic effect and gamma photons that make it possible to take images of the skeleton and locate and characterize the size and nature of tumors.
