Gielen E, Aldvén M, Kanis JA, Borgström F, Senior E, Willems D. Cost-effectiveness of romosozumab for the treatment of postmenopausal women with osteoporosis at high risk of fracture in Belgium. Osteoporos Int 2024; 35:1173-1183. [PMID: 38565690 PMCID: PMC11211114 DOI: 10.1007/s00198-024-07043-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 02/20/2024] [Indexed: 04/04/2024]
Abstract
This study evaluated the cost-effectiveness of sequential treatment with romosozumab-to-alendronate compared to alendronate monotherapy and teriparatide-to-alendronate, in postmenopausal osteoporotic women from a Belgian healthcare perspective. Romosozumab-to-alendronate was found to be cost-effective compared to alendronate monotherapy and dominant compared to teriparatide-to-alendronate for osteoporotic women at high risk of fracture in Belgium. PURPOSE This study aimed to evaluate the cost-effectiveness of sequential treatment with romosozumab followed by alendronate compared to alendronate monotherapy and teriparatide followed by alendronate, in postmenopausal osteoporotic women at high risk of fracture, from a Belgian healthcare perspective. Romosozumab is reimbursed in Belgium since December 2021. METHODS A Markov microsimulation model was used to evaluate the cost-effectiveness of romosozumab-to-alendronate compared to alendronate monotherapy and to teriparatide-to-alendronate over a lifetime horizon. Patients transition between five different health states every 6 months based on fracture risks or death. The model was populated with Belgium-specific epidemiological and cost data, where available. The fracture risk reduction of romosozumab treatment was collated from the ARCH study, and from a published network meta-analysis. Costs were included from a healthcare perspective (NIHDI). Cost-effectiveness was reported in terms of costs per quality-adjusted life year (QALY), reported in Euro (€) 2022. Deterministic (DSA) and probabilistic sensitivity analyses (PSA) were performed. RESULTS Romosozumab-to-alendronate was associated with 0.12 additional QALYs at an additional cost of €2314 compared to alendronate monotherapy, resulting in an ICER of €19,978. Compared to teriparatide-to-alendronate, romosozumab-to-alendronate was found to be dominant, with higher QALYs and lower costs. The base-case results were robust to uncertainty in the input parameters when conducting the sensitivity analysis. CONCLUSION Sequential treatment with romosozumab followed by alendronate was found to be cost-effective compared to alendronate monotherapy and dominant compared to teriparatide followed by alendronate for postmenopausal women with osteoporosis at high risk of fracture in Belgium.

Injectable and high-strength PLGA/CPC loaded ALN/MgO bone cement for bone regeneration by facilitating osteogenesis and inhibiting osteoclastogenesis in osteoporotic bone defects. Mater Today Bio 2024; 26:101092. [PMID: 38873105 PMCID: PMC11169522 DOI: 10.1016/j.mtbio.2024.101092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 04/18/2024] [Accepted: 05/14/2024] [Indexed: 06/15/2024] Open
Abstract
Osteoporosis (OP) can result in slower bone regeneration than the normal condition due to the imbalance between osteogenesis and osteoclastogenesis, making osteoporotic bone defects healing a significant clinical challenge. Calcium phosphate cement (CPC) is a promising bone substitute material due to its good osteoinductive activity, however, the drawbacks such as fragility, slow degradation rate and incapability to control bone loss restrict its application in osteoporotic bone defects treatment. Currently, we developed the PLGA electrospun nanofiber sheets to carry alendronate (ALN) and magnesium oxide nanoparticle (nMgO) into CPC, therefore, to obtain a high-strength bone cement (C/AM-PL/C). The C/AM-PL/C bone cement had high mechanical strength, anti-washout ability, good injection performance and drug sustained release capacity. More importantly, the C/AM-PL/C cement promoted the osteogenic differentiation of bone marrow mesenchymal stem cells and neovascularization via the release of Mg2+ (from nMgO) and Ca2+ (during the degradation of CPC), and inhibited osteoclastogenesis via the release of ALN in vitro. Moreover, the injection of C/AM-PL/C cement significantly improved bone healing in an OP model with femur condyle defects in vivo. Altogether, the injectable C/AM-PL/C cement could facilitate osteoporotic bone regeneration, demonstrating its capacity as a promising candidate for treatment of osteoporotic bone defects.

Comparison of the cost-effectiveness of sequential treatment with abaloparatide in US men and women at very high risk of fractures. Aging Clin Exp Res 2024; 36:14. [PMID: 38289413 PMCID: PMC10827834 DOI: 10.1007/s40520-023-02682-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 11/03/2023] [Indexed: 02/01/2024]
Abstract
BACKGROUND Osteoporotic-related fractures represent an increasing burden to patients, health care systems and society. AIMS This study estimated cost-effectiveness of sequential treatment with abaloparatide (ABL) followed by alendronate (ALN) compared to relevant alternative strategies in US men and women aged 50 to 80 years at very high fracture risk (bone mineral density T-score ≤ - 2.5 and a recent fracture). METHODS A lifetime Markov-based microsimulation model was used to estimate healthcare costs and quality-adjusted life years (QALYs). Comparators were sequential treatment with unbranded teriparatide (TPTD)/ALN, generic ALN monotherapy, and no treatment. Analyses were conducted based on initial fracture site (hip, vertebral, or any fracture) and treatment efficacy data (derived from clinical trials or a recent network meta-analysis). RESULTS From all analyses completed, sequential ABL/ALN demonstrated more QALYs for lower healthcare costs versus unbranded TPTD/ALN. No treatment was dominated (higher costs for less QALYs) versus ALN monotherapy. Sequential ABL/ALN resulted in favorable cost-effectiveness (at US threshold of $150,000/QALY) versus generic ALN monotherapy in men aged ≥ 50 years with any fracture type, women aged ≥ 65 years with any fracture type, and women aged ≥ 55 years having a hip or vertebral fracture. DISCUSSION Similar cost-effectiveness of sequential ABL/ALN versus unbranded TPTD/ALN, ALN monotherapy, and no treatment was observed in both US men and women at very high fracture risk, with a moderate improvement in cost-effectiveness in men versus women and in patients with a hip or vertebral fracture. CONCLUSIONS Sequential therapy with ABL/ALN was cost-effective in US men and women at very high risk of fractures.

Abstract
DESCRIPTION This guideline updates the 2017 American College of Physicians (ACP) recommendations on pharmacologic treatment of primary osteoporosis or low bone mass to prevent fractures in adults. METHODS The ACP Clinical Guidelines Committee based these recommendations on an updated systematic review of evidence and graded them using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. AUDIENCE AND PATIENT POPULATION The audience for this guideline includes all clinicians. The patient population includes adults with primary osteoporosis or low bone mass. RECOMMENDATION 1A ACP recommends that clinicians use bisphosphonates for initial pharmacologic treatment to reduce the risk of fractures in postmenopausal females diagnosed with primary osteoporosis (strong recommendation; high-certainty evidence). RECOMMENDATION 1B ACP suggests that clinicians use bisphosphonates for initial pharmacologic treatment to reduce the risk of fractures in males diagnosed with primary osteoporosis (conditional recommendation; low-certainty evidence). RECOMMENDATION 2A ACP suggests that clinicians use the RANK ligand inhibitor (denosumab) as a second-line pharmacologic treatment to reduce the risk of fractures in postmenopausal females diagnosed with primary osteoporosis who have contraindications to or experience adverse effects of bisphosphonates (conditional recommendation; moderate-certainty evidence). RECOMMENDATION 2B ACP suggests that clinicians use the RANK ligand inhibitor (denosumab) as a second-line pharmacologic treatment to reduce the risk of fractures in males diagnosed with primary osteoporosis who have contraindications to or experience adverse effects of bisphosphonates (conditional recommendation; low-certainty evidence). RECOMMENDATION 3 ACP suggests that clinicians use the sclerostin inhibitor (romosozumab, moderate-certainty evidence) or recombinant PTH (teriparatide, low-certainty evidence), followed by a bisphosphonate, to reduce the risk of fractures only in females with primary osteoporosis with very high risk of fracture (conditional recommendation). RECOMMENDATION 4 ACP suggests that clinicians take an individualized approach regarding whether to start pharmacologic treatment with a bisphosphonate in females over the age of 65 with low bone mass (osteopenia) to reduce the risk of fractures (conditional recommendation; low-certainty evidence).
