Animal experiments show a dramatic improvement in skeletal repair by teriparatide. We tested the hypothesis that recombinant teriparatide, at the 20 mg dose normally used for osteoporosis treatment or higher, would accelerate fracture repair in humans. Postmenopausal women (45 to 85 years of age) who had sustained a dorsally angulated distal radial fracture in need of closed reduction but no surgery were randomly assigned to 8 weeks of once-daily injections of placebo (n ¼ 34) or teriparatide 20 mg (n ¼ 34) or teriparatide 40 mg (n ¼ 34) within 10 days of fracture. Hypotheses were tested sequentially, beginning with the teriparatide 40 mg versus placebo comparison, using a gatekeeping strategy. The estimated median time from fracture to first radiographic evidence of complete cortical bridging in three of four cortices was 9.1, 7.4, and 8.8 weeks for placebo and teriparatide 20 mg and 40 mg, respectively (overall p ¼ .015). There was no significant difference between the teriparatide 40 mg versus placebo groups ( p ¼ .523). In post hoc analyses, there was no significant difference between teriparatide 40 mg versus 20 mg (p ¼ .053); however, the time to healing was shorter in teriparatide 20 mg than placebo ( p ¼ .006). The primary hypothesis that teriparatide 40 mg would shorten the time to cortical bridging was not supported. The shortened time to healing for teriparatide 20 mg compared with placebo still may suggest that fracture repair can be accelerated by teriparatide, but this result should be interpreted with caution and warrants further study. ß

This study evaluated the long-term safety and efficacy of dapagliflozin as an adjunct to adjustable insulin in patients with type 1 diabetes and inadequate glycemic control. RESEARCH DESIGN AND METHODS DEPICT-1 (Dapagliflozin Evaluation in Patients With Inadequately Controlled Type 1 Diabetes) was a randomized (1:1:1), double-blind, placebo-controlled phase 3 study of dapagliflozin 5 mg and 10 mg in patients with type 1 diabetes (HbA 1c 7.5-10.5% [58-91 mmol/mol]) (NCT02268214). The results of the 52-week study, consisting of the 24-week short-term and 28-week extension period, are reported here. RESULTS Of the 833 patients randomized into the study, 708 (85%) completed the 52-week study. Over 52 weeks, dapagliflozin 5 mg and 10 mg led to clinically significant reductions in HbA 1c (difference vs. placebo [95% CI] 20.
