Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Metformin hydrochloride is a biguanide antihyperglycemic agent that improves glucose tolerance in patients with type 2 diabetes mellitus. It primarily decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization.
POHERDY is a monoclonal antibody targeting the human epidermal growth factor receptor 2 (HER2), binding to domain IV of the extracellular segment, thereby inhibiting ligand-independent HER2 signaling and mediating antibody-dependent cellular cytotoxicity (ADCC).
Locametz (gallium Ga 68 gozetotide) is administered intravenously at a dose of 3-5 mCi (110-185 MBq) as a single injection for PET imaging. No repeated dosing schedule is defined.
POHERDY: No approved drug. No dosing available.
