Teriparatide can be considered in premenopausal women with idiopathic osteoporosis

Key clinical point: Teriparatide improves bone formation rate (BFR), bone turnover markers, and spine and hip bone density in premenopausal women with idiopathic osteoporosis (IOP).

Major finding: At 6 months, teriparatide significantly increased lumbar spine (LS) areal bone mineral density (aBMD) vs placebo (percentage change: 5.51% vs. 1.55%; P = .007). At 24 months, teriparatide significantly increased aBMD of LS, total hip, and femoral neck (percentage change: 13.2%, 5.2%, and 5.0%, respectively; P ≤. 001 for all). Cancellous and intracortical BFR increased 3.3-fold (P ≤. 001) and 1.9-fold (P ≤. 001), respectively, in the teriparatide group with no change in placebo group. Serum N-terminal propeptides of procollagen type 1, osteocalcin, and C-telopeptide increased significantly by 3 months with teriparatide treatment.

Study details: The data come from a phase 2 trial of 41 premenopausal women with IOP who were randomly assigned to either teriparatide 20 mcg (n = 28) or placebo (n = 13). After 6 months, placebo group was switched to teriparatide for 24 months, and the teriparatide group continued the drug for 18 months.
