Q BioMed Seeks Approval for New Manufacturing Site
Q BioMed has filed with FDA for approval of a new manufacturing facility to make strontium chloride Sr89 injection USP, a non-opioid injectable radiopharmaceutical to relieve cancer bone pain in patients with painful skeletal metastases. In the body, strontium acts similar to calcium, selectively localizing in bone and osteoblastic lesions, according to the company. The unabsorbed isotope clears rapidly from the blood and is excreted in the urine during the first three days following injection. “Strontium-89 is a pure beta emitter, and selectively irradiates sites of primary and metastatic bone involvement with minimal irradiation of soft tissues distant from bone lesions,” it says. “The presence of bone metastases should be confirmed prior to therapy.”
