QSAM Biosciences (OTCQB: QSAM) is a company developing next-generation targeted therapeutic radiopharmaceuticals, including Samarium-153-DOTMP (“CycloSam(R)”), for the treatment of cancer and related diseases. The company today announced that the United States Patent & Trademark Office has granted a key patent protecting how CycloSam(R) is formulated and prepared, namely by using a nonradioactive kit that can be delivered and stored local to the administration site and provides for high purity in an efficient, facile and reproducible process at lower costs. “This patent issuance marks our third granted patent in the United States and further strengthens our IP estate, consisting of 14 patents among three distinct patent families,” said Douglas R. Baum, CEO and co-founder of QSAM Biosciences. “Preparation and delivery of radiopharmaceuticals has historically been a challenge, but we believe the protection we have received for our kit formulation and preparation can provide a marketable advantage for both the manufacturing and supply chain for CycloSam(R) as well as potentially other drug candidates. We also believe CycloSam(R) has potential to be a breakthrough therapy for both primary and secondary forms of bone cancer.”

About QSAM Biosciences Inc.
QSAM Biosciences is developing next-generation nuclear medicines for the treatment of cancer and related diseases. QSAM’s initial technology, CycloSam(R) (Samarium-153 DOTMP), is a clinical-stage bone-targeting radiopharmaceutical developed by IsoTherapeutics Group LLC, pioneers in the nuclear medicine space who also developed the FDA-approved Quadramet(R) (Samarium-153 EDTMP) radiopharmaceutical product, which is indicated for pain palliation. QSAM is led by an experienced executive team and board of directors that have completed numerous FDA approvals and multiple successful biotech exits. CycloSam(R) has demonstrated preliminary safety and efficacy in animal studies and a single patient FDA-cleared human trial performed in 2020 at the Cleveland Clinic. This nuclear technology uses low specific activity Samarium-153 (resulting in far less long-lived europium impurities) and DOTMP, a chelator believed to reduce or eliminate off-target migration and targets sites of high bone turnover, making it, in management’s opinion, an ideal agent to treat primary and secondary bone cancers. Since CycloSam(R) delivers targeted radiation selectively to the skeletal system and to bone tumors, it is also believed to be a great candidate for effectiveness trials in bone marrow ablation as preconditioning for bone marrow transplantation, as well as in procedures to reduce external beam radiation to bone tumors. This multi-patented drug candidate utilizes a radioisotope previously approved by the FDA combined with a novel chelant, DOTMP, that has demonstrated preliminary increased efficacy and decreased side effects in animal models and veterinary treatment of bone cancer in dogs. Further, CycloSam(R) utilizes a streamlined, just-in-time manufacturing process that is already in place. Given these factors, management believes there is a strong pathway to commercialization for CycloSam(R). For more information, visit the company’s website at https://QSAMBio.com.
