Skeletal effects of bazedoxifene paired with conjugated estrogens in ovariectomized rats.

A novel approach to menopausal therapy is the tissue selective estrogen complex (TSEC) that partners bazedoxifene (BZA) with conjugated estrogens (CE). We examined the effects of daily treatment with BZA 0.3mg/kg, CE 2.

Inhibition of sclerostin by monoclonal antibody enhances bone healing and improves bone density and strength of nonfractured bones.

Therapeutic enhancement of fracture healing would help to prevent the occurrence of orthopedic complications such as nonunion and revision surgery. Sclerostin is a negative regulator of bone formation, and treatment with a sclerostin monoclonal antibody (Scl-Ab) results in increased bone formation and bone mass in animal models. Our objective was to investigate the effects of systemic administration of Scl-Ab in two models of fracture healing.

Two doses of sclerostin antibody in cynomolgus monkeys increases bone formation, bone mineral density, and bone strength.

The development of bone-rebuilding anabolic agents for treating bone-related conditions has been a long-standing goal. Genetic studies in humans and mice have shown that the secreted protein sclerostin is a key negative regulator of bone formation. More recently, administration of sclerostin-neutralizing monoclonal antibodies in rodent studies has shown that pharmacologic inhibition of sclerostin results in increased bone formation, bone mass, and bone strength.
