IsoTherapeutics joins The Gabriel Institute to visit Skylar one year after her treatment.
Skylar received a novel treatment for bone cancer being developed by IsoTherapeutics and The Gabriel Institute. The efficacy of this novel therapy is being evaluated by ongoing clinical trials which are looking promising.

IsoTherapeutics Group awarded NIH grant for advancing treatment of bone cancer
IsoTherapeutics Group, LLC has been awarded a Phase II SBIR grant for its development of CycloSam® Sm-153-DOTMP for treating bone cancer. Early findings show that CycloSam is a bone seeking agent indicated not only for the relief of pain from bone metastases, but also for treating primary osteosarcoma. These findings were established as a result of a Phase I NCI SBIR research grant in 2010-11.1 The success with this initial study culminated in a second SBIR award for furthering the development of CycloSam, specifically the chemistry, manufacture and control information, development of a non-clinical toxicology study program, and preparation of a Phase 1 clinical protocol for first-in-human clinical studies with CycloSam. Based on our early findings in studies performed in canines bearing spontaneous osteosarcomas, IsoTherapeutics’ Scientists and advisors have reason to believe that CycloSam will prove beneficial and advantageous to patients with bone metastases. It induces less myelotoxicity than Quadramet® Sm-153-EDTMP and potentially allows concurrent CycloSam and chemotherapy treatment.

IsoTherapeutics Group Awarded DOE SBIR Phase 1 for developing method for producing high specific activity Sn-177m
R. Keith Frank, Ph.D., CEO of IsoTherapeutics Group, is pleased to announce that the DOE has awarded a Phase I SBIR grant to IsoTherapeutics for developing a method for producing high specific activity (SA) Sn-117m. The technical approach for producing commercially useful amounts of high purity Sn-117m is to perform electromagnetic enrichment of low SA reactor-produced material. John D’Auria, Ph.D., principal investigator for the project, commented that Electro-Magnetic Isotope Separation (EMIS) is routinely used in the production of enriched stable isotopes and in mass spectrometry; however, the successful development of an economically viable facility for processing relatively short-lived radioactive medical isotopes presents new challenges. We are developing the technique in a related Phase II SBIR project that is producing high SA samarium-153 for the first time. While our experience with Sm-153 gives us great confidence in the general approach, the physical chemistry of each element presents unique challenges for each radioisotope being considered.
IsoTherapeutics, with its customers/collaborators, have been engaged with radiolabeling of Sn-117m with proteins for a number of years. This radioisotope is considered a theranostic isotope that is suitable for both diagnostic and therapeutic applications. Its low energy gamma emissions (158 keV) can be imaged using standard gamma cameras and collimators routinely used for technetium-99m (140 keV). For therapy, its conversion electrons (127, 129 and 152 keV; abundance 65, 12 and 26% respectively) exhibit high linear energy transfer over a short range (<300 micron), which minimizes damage to healthy tissue. These emissions, along with its 13.6 day half-life, make Sn-117m of interest in a variety of applications in oncology, rheumatology, ophthalmology, and neurology according to Dr. Jaime Simón, Ph.D., Chief Scientific Officer of IsoTherapeutics.

“Liqiud Brachytherapy” Treats Osteosarcoma
PET/CT Image of OS in Distal Radius
“Liquid Brachytherapy,” a novel technology for the treatment of inoperable tumors, jointly developed by IsoTherapeutics and The Gabriel Institute, has now been evaluated in 16 cases of canine osteosarcoma with very promising results. The latest treatment on “Juno,” a 160 lb Saint Bernard was preformed at the new Texas A&M Institute for Preclinical Studies (TIPS). This was, in fact, the first clinical case treated at the new facility. TIPS brings state-of-the-art imaging capabilities to our efforts to move this technology forward. Juno’s treatment was featured recently in MIT Technology Review.

Kenneth McMillan Memorial Scholarship
The Kenneth McMillan Memorial Scholarship is being initiated to honor the memory of our late long-term friend and colleague Kenneth McMillan. The scholarship will be awarded annually to a deserving high school senior from the Brazosport Independent School District. Kenneth had a long career at The Dow Chemical Company, working along side us for over twenty years. When we formed IsoTherapeutics, Kenneth joined us and served as our Radiation Safety Officer and Laboratory Director until his untimely passing in December of 2008.
