Company expects Strontium Chloride Sr89 Injection, USP for the non-narcotic treatment of painful skeletal cancer metastases to be available in late October 2017
NEW YORK, October 5, 2017 /PRNewswire/ —
Q BioMed Inc. (OTCQB: QBIO), a biotechnology acceleration Company, announced today the launch of http://www.PainFreeCancer.com. This website is designed to provide a resource for patients, doctors and caregivers dealing with the severe pain associated with late stage cancer metastases to the bone.
U.S. Food and Drug Administration approved Generic Strontium Chloride Sr89 Injection, USP; (Strontium-89) is a Non-Opioid pharmaceutical injection to relieve bone pain in patients with painful skeletal metastases. In the body, Strontium-89 acts similar to calcium and is preferentially taken up in osteoblastic tissue selectively localizing in bone mineral. Uptake of strontium by bone occurs preferentially in sites of active osteogenesis; thus primary bone tumors and areas of metastatic involvement (blastic lesions) can accumulate significantly greater concentrations of strontium than surrounding normal bone. Up to 80% of patients report pain relief lasting for months.
Strontium Chloride Sr89 Injection, USP can be used in combination with other therapeutic drugs. Clinical studies have demonstrated that the combination of alternating weekly chemohormonal therapies with Strontium-89 demonstrated a prolonged progression-free and overall survival in patients.

Strontium Chloride Sr89 Injection, USP Usage and Indications:
Following intravenous injection, soluble strontium compounds behave like their calcium analogs, clearing rapidly from the blood and selectively localizing in bone mineral. Uptake of strontium by bone occurs preferentially in sites of active osteogenesis, thus primary bone tumors and areas of metastatic involvement (blastic lesions) can accumulate significantly greater concentrations of strontium than surrounding normal bone. Strontium-89 is retained in metastatic bone lesions much longer than in normal bone, where turnover is about 14 days. In patients with extensive skeletal metastases, well over half of the injected dose is retained in the bones. Strontium-89 is a pure beta emitter and Strontium-89 selectively irradiates sites of primary and metastatic bone involvement with minimal irradiation of soft tissues distant from the bone lesions. (The maximum range in tissue is 8 mm; maximum energy is 1.463 MeV.) Clinical trials have examined relief of pain in cancer patients who have received therapy for bone metastases (external radiation to indexed sites) but in whom persistent pain recurred.
INDICATIONS AND USAGE: Strontium-89 Chloride Injection is indicated for the relief of bone pain in patients with painful skeletal metastases. The presence of bone metastases should be confirmed prior to therapy.
CONTRAINDICATIONS: None known.
WARNINGS: Use of Strontium-89 (Sr89) in patients with evidence of seriously compromised bone marrow from previous therapy or disease infiltration is not recommended unless the potential benefit of the treatment outweighs its risks. Bone marrow toxicity is to be expected following the administration of Strontium-89, particularly white blood cells and platelets. The extent of toxicity is variable. It is recommended that the patient’s peripheral blood cell counts be monitored at least once every other week. Typically, platelets will be depressed by about 30% compared to pre-administration levels. The nadir of platelet depression in most patients is found between 12 and 16 weeks following administration of Sr89. White blood cells are usually depressed to a varying extent compared to pre-administration levels. Thereafter, recovery occurs slowly, typically reaching pre-administration levels six months after treatment unless the patient’s disease or additional therapy intervenes. In considering repeat administration of Sr89, the patient’s hematologic response to the initial dose, current platelet level and other evidence of marrow depletion should be carefully evaluated. Verification of dose and patient identification is necessary prior to administration because Sr89 delivers a relatively high dose of radioactivity. Sr89 may cause fetal harm when administered to a pregnant woman. There are no adequate and well-controlled studies in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while receiving this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant.
