QSAM Biosciences (OTCQB: QSAM), a clinical-stage biotechnology company, is focused on bringing to market targeted therapeutic radiopharmaceuticals. “The company is committed to advancing the fight against cancer through the discovery, development and delivery of effective treatment options for adult and pediatric patients,” a recent article reads. “CycloSam(R), QSAM Biosciences’ initial technology, is a clinical-stage bone targeting radiopharmaceutical invented by world-renowned scientists at IsoTherapeutics Group LLC. … CycloSam is designed to selectively target sites of high bone mineral turnover to deliver a prescribed tumor-killing dose of radiation to the tumor sites while minimizing radiation exposure to nearby healthy tissue. These parameters are currently being tested in an FDA-cleared clinical trial. CycloSam has been shown in laboratory testing to cause significantly less (30x less) buildup of long-lived radionuclidic impurities than prior FDA-approved drugs, which management believes will enable the ability to safely administer therapeutic doses via higher and multiple-dose regimens and effectively expand its potential clinical utility to therapeutic uses in areas of high unmet medical needs. The indications for CycloSam currently being evaluated by QSAM Biosciences include: metastatic bone cancers; pediatric osteosarcoma/Ewing’s sarcoma; and bone marrow ablation… The company has secured 14 patents across three distinct patent families spanning the U.S., Japan, Canada, and the European Union.”

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 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 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 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. For more information, visit the company’s website at https://QSAMBio.com.
