Teriparatide and denosumab, alone or combined, in women with postmenopausal osteoporosis: the DATA study randomised trial.

ABSTRACT: BACKGROUND:Osteoporosis medications increase bone-mineral density (BMD) and lower but do not eliminate fracture risk. The combining of anabolic agents with bisphosphonates has not improved efficacy. We compared combined teriparatide and denosumab with both agents alone. METHODS:From September, 2009, to January, 2011, we enrolled postmenopausal women with osteoporosis into this randomised, controlled trial. Patients were assigned in a 1:1:1 ratio to receive 20 ?g teriparatide daily, 60 mg denosumab every 6 months, or both. BMD was measured at 0, 3, 6, and 12 months. Women who completed at least one study visit after baseline were assessed in a modified intention-to-treat analysis. This trial is registered with ClinicalTrials.gov, number NCT00926380. FINDINGS:94 (94%) of 100 eligible women completed at least one study visit after baseline. At 12 months, posterior-anterior lumbar spine BMD increased more in the combination group (9·1%, [SD 3·9]) than in the teriparatide (6·2% [4·6], p=0·0139) or denosumab (5·5% [3·3], p=0·0005) groups. Femoral-neck BMD also increased more in the combination group (4·2% [3·0]) than in the teriparatide (0·8% [4·1], p=0·0007) and denosumab (2·1% [3·8], p=0·0238) groups, as did total-hip BMD (combination, 4·9% [2·9]; teriparatide, 0·7% [2·7], p<0·0001; denosumab 2·5% [2·6], p=0·0011). INTERPRETATION:Combined teriparatide and denosumab increased BMD more than either agent alone and more than has been reported with approved therapies. Combination treatment might, therefore, be useful to treat patients at high risk of fracture. FUNDING:Amgen, Eli Lilly, National Center for Research Resources.

Project description:BackgroundIn the Denosumab and Teriparatide Administration (DATA) study, we showed that denosumab fully inhibits teriparatide-induced bone resorption while allowing for continued teriparatide-induced bone formation, resulting in larger increases in hip and spine bone mineral density (BMD) than with either drug alone. We aimed to assess whether administration of denosumab with high dose teriparatide would stimulate larger increases in bone mass than those observed in the DATA study.MethodsDATA-HD was an open-label, randomised, controlled phase 4 trial done at Massachusetts General Hospital. Eligible women were postmenopausal women (at least 36 months since last menses or since hysterectomy with a follicle-stimulating hormone concentration of ≥40 U/L) with osteoporosis. Participants were randomly assigned (1:1) to receive teriparatide 20 μg (standard dose) or 40 μg (high dose) daily via subcutaneous injection for 9 months. At 3 months, both groups were started on denosumab 60 mg every 6 months via subcutaneous injection for 12 months. Areal BMD (aBMD) was measured at 0, 3, 9, and 15 months. Treatment was given open label, but outcome assessors were masked. The primary endpoint was percentage change from baseline in spine areal BMD (aBMD) at 15 months. Women who completed at least one study visit after baseline were included in the modified intention-to-treat analysis. Safety was assessed in all randomly assigned participants. This study is registered with ClinicalTrials.gov, number NCT02176382.FindingsBetween Oct 15, 2014, and June 10, 2016, 269 women were assessed for eligibility. 76 participants were randomly assigned to 20 μg teriparatide (n=39) or 40 μg teriparatide (n=37), of whom 69 completed at least one post-baseline visit. At 15 months, mean spine aBMD had increased to a significantly greater extent in the 40 μg group (17·5% [SD 6·0] increase) than the 20 μg group (9·5% [3·2]; difference 8·1%, 95% CI 5·5 to 10·6, p<0·0001). Mean femoral neck aBMD had also increased to a greater extent in the 40 μg group (6·8% [SD 4·1] increase) than the 20 μg group (4·3% [3·7]; difference 2·5%, 0·5 to 4·5, p=0·04), as did mean total hip aBMD (40 μg group, 6·1% [3·4] increase; 20 μg group, 3·9% [2·9] increase; difference 2·2%, 0·6 to 3·8, p<0·0001). 30 (77%) of 39 participants in the 20 μg group and 29 (78%) of 37 participants in the 40 μg group had an adverse event, and seven (18%) and two (5%) patients had serious adverse events. The most frequent adverse events were joint pain (15 [38%]), muscle cramp (15 [38%]), and fatigue (12 [31%]) in the 20 μg group group and fatigue (14 [38%]), nausea (16 [43%]), and joint pain (17 [46%]) in the 40 μg group. No deaths were reported.InterpretationCombined treatment with teriparatide 40 μg and denosumab increases spine and hip BMD more than standard combination therapy. This large and rapid increase in bone mass suggest that this high dose regimen might provide a method of restoring skeletal integrity in patients with osteoporosis.FundingNational Institutes of Health and the Dart Foundation.

Project description:Current osteoporosis medications increase bone mineral density (BMD) modestly and reduce, but do not eliminate, fracture risk. Attempts to improve efficacy by administering anabolic agents and bisphosphonates concomitantly have been unsuccessful. Conversely, 12 months of concomitant denosumab and teriparatide therapy increases BMD more than either drug alone.The purpose of this study was to determine whether 24 months of combined denosumab and teriparatide will increase hip and spine BMD more than either individual agent.Preplanned continuation of the Denosumab and Teriparatide Administration (DATA) randomized controlled trial in which postmenopausal osteoporotic women received teriparatide (20 ?g daily), denosumab (60 mg every 6 months), or both medications for 24 months.Participants were 94 postmenopausal women with osteoporosis.Lumbar spine, femoral neck, total hip, and distal radius BMD and serum markers of bone turnover were measured.At 24 months, lumbar spine BMD increased more in the combination group (12.9 ± 5.0%) than in either the teriparatide (9.5 ± 5.9%, P = .01) or denosumab (8.3 ± 3.4%, P = .008) groups. Femoral neck BMD also increased more in the combination group (6.8 ± 3.6%) than in either the teriparatide (2.8 ± 3.9%, P = .003) or denosumab (4.1 ± 3.8%, P = .008) groups. Similarly, total hip BMD increased more in the combination group (6.3 ± 2.6%) than in the teriparatide (2.0 ± 3.0%) or denosumab (3.2 ± 2.5%) groups (P < .001 for both). Although spine and hip BMD continued to increase in the second year in all groups, these year 2 increases did not differ among groups. Serum C-telopeptide and N-terminal propeptide of type 1 procollagen were equally suppressed in the denosumab and combination groups, whereas osteocalcin decreased more in the denosumab group than in the combination group, a difference that persisted, but lessened, in the second year of therapy.Two years of concomitant teriparatide and denosumab therapy increases BMD more than therapy with either medication alone and more than has been reported with any current therapy. The combination of these agents may prove to be an important treatment option in patients at high risk of fracture.

Project description:ContextIn postmenopausal women, bone mineral density (BMD) declines after teriparatide therapy is stopped. The pattern of BMD loss after teriparatide therapy is stopped in men is less clear.ObjectiveThe aim of the study was to determine whether the pattern of teriparatide-induced bone accrual and post-teriparatide bone loss differs between postmenopausal women and eugonadal men.DesignWe conducted a prospective cohort substudy.PatientsThe study included 14 postmenopausal women and 17 eugonadal men, ages 46-85 yr, with lumbar spine or femoral neck BMD T-scores below -2.InterventionTeriparatide (37 microg sc daily) was administered for 24 months, followed by 12 months off therapy.Main outcome measuresWe measured BMD at various anatomic sites by dual-energy x-ray absorptiometry, trabecular spine BMD by quantitative computed tomography, and bone turnover markers during the treatment and observation periods. The response to teriparatide administration and discontinuation was compared between females and males.ResultsBMD of the spine, femoral neck, total hip, and trabecular spine increased similarly during the treatment period in men and women, whereas BMD at the radius was stable in men but decreased by 8.1 +/- 3.3% in women (P < 0.0001). After teriparatide was stopped, BMD at the posterior-anterior spine decreased by 7.1 +/- 3.8% in women and by 4.1 +/- 3.5% in men (P = 0.036). BMD at the total hip and femoral neck decreased by 3.8 +/- 3.9 and 3.1 +/- 4.3%, respectively, in women but remained stable in men (P < 0.05 for both sites). BMD at the distal radius remained stable in men but increased in women by 1.6 +/- 3.1% (P = 0.069).ConclusionsTeriparatide appears to increase BMD similarly in postmenopausal women and eugonadal men with osteoporosis. After teriparatide is stopped, the decline in BMD is greater in women than in men. If confirmed in larger cohorts, these findings would suggest that the indication for immediate antiresorptive therapy after teriparatide may not be as urgent in men as in women.
