Our Story

QSAM Biosciences is developing
next generation radiopharmaceuticals
for the treatment of cancer.

QSAM Biosciences (OTCQB: QSAM) is a clinical stage biotechnology company focused on bringing to market targeted, therapeutic radiopharmaceuticals

Our initial technology is Samarium-153 DOTMP, aka CycloSam®, a clinical-staged bone targeting radiopharmaceutical developed by IsoTherapeutics, leaders in the nuclear medicine space who also developed FDA-approved Quadramet® (Samarium-153 EDTMP), indicated for pain palliation. 

CycloSam® was cleared by the FDA to commence clinical trials on patients with both metastatic and pediatric primary bone cancer, and patient enrollment in Phase 1 clinical trials commenced in early 2022.

QSAM received Orphan Drug Designation and Rare Pediatric Disease Designation for CycloSam® in the treatment of osteosarcoma, a devastating form of bone cancer that primarily affects children and young adults.   

Our mission is to treat cancer in children and adults through the development of next-generation radiopharmaceuticals.  We plan to achieve this goal through a commitment to solid science, investments in technology with strong evidence of safety and efficacy, and efficient use of capital resources.
