Abstract
Introduction
Osteoporosis is estimated to affect 200 million women globally (1). Osteoporosis causes significant disability, surpassing most cancers (except lung cancer) and numerous chronic diseases. It has substantial economic implications, with fragility fractures costing Europe €37.5 billion in 2017, a figure projected to increase by 27% in 2030(2).
Chronic kidney disease (CKD) is associated with an increased incidence of fractures due to CKD-mineral bone disorder and uremic osteoporosis is exacerbated by CKD-specific factors, including uremic toxins. Consequently, osteoporosis and CKD are prevalent comorbidities in the elderly population and frequently coexist.
In Japan, recent data suggest that >14 million individuals are estimated to have CKD, with the number of chronic dialysis patients reaching 2,754 per million in 2020 and continuing to rise annually (3). Globally, ~700 million individuals are estimated to have CKD (4).
Nickolas et al (5) reported a significantly increased incidence of hip fractures in patients with an estimated glomerular filtration rate (eGFR) of <60 ml/min/1.73 m2 (odds ratio, 2.12; 95% confidence interval, 1.18-3.80). In the Dialysis Outcomes and Practice Patterns Study report, the incidence of fractures was significantly higher in dialysis patients than in the general population (6). Therefore, treatment for osteoporosis among patients with CKD is an important issue. However, there is currently no gold standard for osteoporosis treatment among patients with CKD or a history of kidney transplantation. In a recent systematic review and meta-analysis by Chen et al (7), teriparatide and denosumab exhibited the highest efficacy in improving bone mineral density (BMD) in the vertebrae and femoral neck (FN) of patients with CKD. Conversely, the use of teriparatide or denosumab in patients with end-stage CKD has been reported to elevate the risk of transient hypotension or severe hypocalcemia (8,9).
Romosozumab (ROMO) is a humanized monoclonal antibody that binds to sclerostin, which is a key inhibitor of bone formation, thereby increasing bone formation and reducing bone resorption. ROMO was approved in March 2019 in Japan for patients with osteoporosis and a high fracture risk. Previous research has demonstrated that ROMO significantly increases BMD in the lumbar spine (LS), total hip, and FN, while reducing the risk of both vertebral and non-vertebral fractures (10). For example, in the FRAME study, it reduced the risk of new vertebral fractures by 73% compared with placebo over 12 months (P<0.001) (10).
ROMO is contraindicated in patients with hypocalcemia. No dose adjustment is required in patients with renal impairment; however, careful prescription is needed for those with eGFR <60 ml/min/1.73 m2 or those undergoing dialysis, as hypocalcemia appears to be more common. Post hoc analysis of results from the placebo-controlled phase 3 FRAME study and the active-controlled phase 3 ARCH showed the efficacy and safety of ROMO in postmenopausal women with osteoporosis and reduction in kidney function (eGFR of 30-90 ml/min/1.73 m2) (11,12). Excluding these post hoc analyses from clinical trials, there is limited evidence for the efficacy and safety of 12 months of ROMO treatment for patients with osteoporosis and reduction in kidney function in actual clinical practice.
Notably, serum 25(OH)D levels are reportedly low in patients with CKD (13,14). Vitamin D and calcium play an essential role in calcium and phosphate homeostasis, as well as bone formation and mineralization. The Kidney Disease: Improving Global Outcomes clinical guidelines recommend monitoring 25(OH)D levels and correcting vitamin D insufficiency and deficiency using treatment strategies recommended for the general population (15).
Most osteoporotic fractures occur due to falls (16). One-third of people >65 fall each year, with the risk of falling increasing with age. The global population of people aged 65 and older is growing at a faster rate than younger age groups, with their share projected to increase from 10% in 2022 to 16% by 2050(17). It is reported that vitamin D supplementations may help prevent falls by enhancing dynamic physical function (18,19).
Data are lacking on the benefits of ROMO and active vitamin D analog combination treatment on clinical outcomes. It is hypothesized that ROMO is effective and safe in patients with osteoporosis regardless of renal function, and the addition of active vitamin D analog [eldecalcitol (ELD)] may provide additional benefits.
The primary objective of the present study was to examine the safety and efficacy of ROMO in patients with and without CKD. The secondary objective was to elucidate the influence of ELD on the effects of ROMO treatment in patients with and without CKD.
Patients and methods
Study subjects
The present retrospective observational cohort study was conducted at Tomidahama Hospital (Yokkaichi, Japan) from January 2019 to December 2023. The total number of included patients was 146 (14 men and 132 women), with an average age of 84±8 years (mean ± SD).
The inclusion criteria for this study were patients aged ≥55 years who underwent 12 months of ROMO therapy for osteoporosis and had a high risk of fractures. The requirement for institutional review board approval from our institute was waived owing to the anonymized and retrospective nature of this study; however, written informed consent was obtained from the patients to perform further research.
Our indication for ROMO treatment was patients at a high risk of fracture. A high risk of fracture was defined as: i) a BMD of <70% of the young adult mean (YAM) of all participants reported in the Japanese Normative Female Database, with a minimum of one prevalent fragility fracture; ii) a BMD of the LS (L1-4) of <60% of the YAM; or iii) >2 previous fragility fractures.
The exclusion criteria were bone metabolic disorders or conditions affecting bone and calcium metabolism, untreated thyroid dysfunction, current parathyroid disorders, abnormal calcium levels, significant cardiopulmonary or liver disease, major psychiatric conditions, excessive alcohol intake, and prior glucocorticoid use.
The study participants were divided into two groups according to their eGFR value at baseline (non-CKD group, eGFR ≥60 ml/min/1.73 m2; and CKD group, eGFR <60 ml/min/1.73 m2). The eGFR value was calculated using the Japanese Modification of Diet in Renal Disease guidelines (20). The primary outcomes were percentage changes in BMD of the LS and FN from baseline to 12 months, as well as the percentage changes in serum total procollagen type I N-terminal propeptide (PINP) from baseline to 1, 4, 8, and 12 months with respect to baseline eGFR. The incidence of new fractures and adverse events were also evaluated at 12 months. In addition, as a secondary outcome, the efficacy of ROMO with or without ELD according to baseline eGFR was evaluated.
Measurements
The BMD of the LS and FN was measured using dual-energy X-ray absorptiometry with a DPX-BRAVO instrument (GE Healthcare) at baseline and at the end of the 12-month treatment. The interobserver percentage coefficient of variability (%CV) was 0.6% for the LS and 0.9% for the FN. The baseline PINP level (normal range, 26.4-98.2 mg/l in postmenopausal women and 18.1-74.1 mg/l in men) was measured using a radioimmunoassay (Orion Diagnostica, Ltd.; Aidian). The intra-assay and inter-assay %CV values for PINP were 3.5 and 4.2%, respectively.
Statistical analysis
For repeated measures data, repeated measures analysis of variance (ANOVA) with Bonferroni correction was applied. Between-group comparisons of the measurements were analyzed using the Mann-Whitney U test.
Differences in categorical variables were assessed using Fisher's exact test. Differences in fracture incidence were assessed using the Kaplan-Meier analysis and log-rank test. All data are expressed as the mean ± standard deviation, unless otherwise indicated. P<0.05 was considered to indicate a statistically significant difference.
In a previous study, the BMD response within each subgroup was found to be normally distributed with standard deviation of 1.1(21). If the true difference in the ROMO and ROMO with ELD group is 3, a sample size of 3 patients per group will be required to reject the null hypothesis that the population means are equal, with probability (power) of 0.8. The type I error probability associated with this test of the null hypothesis is set at 0.05.
All statistical analyses were performed using the EZR graphical user interface (Saitama Medical Center, Jichi Medical University, Saitama, Japan) for the R version 4.4.1 software package (R Foundation for Statistical Computing), which is a modified version of the R Commander designed to add statistical functions commonly used in biostatistics.
Results
Study participants and groups
A flow diagram of the study participants is presented in Fig. 1. This retrospective observational cohort study was conducted at Tomidahama Hospital (Yokkaichi, Japan) from January 2019 to December 2023. A total of 146 patients ranging in age from 56 to 98 years who underwent ROMO therapy were eligible for the present study.
The 146 patients were classified into 2 groups according to their baseline eGFR values (CKD group, N=64 or non-CKD group, N=82). Of the 64 patients in the CKD group, 6 (9.3%) were excluded, as well as 5 (6.1%) of the 82 patients in the non-CKD group, as a result of treatment discontinuation and loss to follow-up, leaving 135 patients selected for analysis. There were no significant differences in completion rates between the two subgroups (P=0.53; Fisher's exact test).
ELD was prescribed at the discretion of the attending clinician, with 33 patients receiving ELD at a fixed dose of 0.75 µg, initiated concurrently with ROMO treatment. A total of 15 (25.9%) patients in the CKD and 18 (23.4%) patients in the non-CKD group underwent ROMO + ELD treatment.
Baseline characteristics
Data including age, sex, height, weight, body mass index, rates of previous vertebral or non-vertebral fractures, baseline mean percentage of YAM at the LS and FN, PINP levels, serum albumin, serum calcium, serum creatinine, baseline serum eGFR, presence of diabetes, serum 25(OH)D levels, and history of osteoporosis treatment are presented in Tables I and II. There were significant differences in age between the CKD and non-CKD groups (P<0.05). In the CKD group, baseline serum PINP levels were significantly higher with ROMO monotherapy than with combination treatment.
Primary outcomes. Changes from baseline BMD
In the CKD group, the LS BMD percentage significantly increased by 10.2±8.3% (P<0.001) after 12 months of ROMO therapy (Fig. 2A) compared with the baseline value. The FN BMD percentage decreased by-0.22±6.1% after 12 months of ROMO therapy, but this change was not statistically significant (P=0.86) compared with the baseline value (Fig. 2B). In the non-CKD group, the LS BMD percentage significantly increased by 12.1±9.8% (P<0.001) after 12 months of ROMO therapy compared with the baseline value (Fig. 2A). The FN BMD percentage increased significantly by 1.7±6.0% (P=0.042) after 12 months of ROMO therapy compared with the baseline value (Fig. 2B). The percentage change in LS and FN BMD values was statistically comparable between the various groups after 12 months of ROMO therapy (P=0.59 and P=0.14, respectively).
Changes in serum PINP levels in response to treatment
In the CKD group, the serum PINP change rate from baseline was 42, -12, -22, and -49% at 1, 4, 8, and 12 months of ROMO treatment, respectively (Fig. 2C). In the non-CKD group, the serum PINP change rate from baseline was 69, 21, -11, and -20% at 1, 4, 8, and 12 months of ROMO treatment, respectively (Fig. 2C). There were no significant differences between either parameter and baseline values at any time point in both groups. There were significant differences at 12 months (P=0.013) between the groups after ROMO treatment.
Adverse events and new fractures
There was one fracture (FN fracture) in the CKD group and no fractures in the non-CKD group. There were no significant differences in fracture incidence between the groups (P=0.25; Table III).
Adverse events that led to treatment discontinuation were reported in 1 patient (hyponatremia) in the CKD group and 2 patients (1 injection site pain and 1 renal dysfunction) in the non-CKD subgroup; there were no significant differences between the groups (P=0.71). No fatal events were reported in either group. No cases of clinical hypocalcemia, defined as calcium levels <7.0 mg/dl and Common Terminology Criteria for Adverse Events v5.0(22) grade 3 or higher, were reported.
Secondary outcomes. Change from baseline BMD
ROMO treatment with and without ELD in the non-CKD and CKD groups, respectively, was compared. The percentage change in BMD after 12 months of ROMO treatment with and without ELD, at two sites in the CKD group is illustrated in Fig. 3A and B. At the LS, the BMD increased by 9.7±3.7% (P<0.001) and 10.4±9.5% (P<0.001), respectively, compared to baseline. At the FN, the BMD changes were 1.02±6.2% (P=0.73) and -0.64±6.1% (P=0.65), respectively, compared to baseline. There were no significant differences between treatment with and without ELD (P=0.45 in the LS BMD; and P=0.60 in the FN BMD). The percentage change in BMD after 12 months of ROMO treatment, with and without ELD, at two sites in the non-CKD group is presented in Fig. 4A and B. At the LS, the BMD increased by 9.0±7.9% (P<0.001) and 13.1±10.3% (P<0.001), respectively, compared to baseline, while at the FN, the BMD changes were 1.9±5.6% (P=0.18) and 1.7±6.2% (P=0.13), respectively, compared to baseline. There were no significant differences between treatment with and without ELD (P=0.26 in the LS BMD; and P=0.56 in the FN BMD).
Changes in serum PINP levels in response to treatment
The serum PINP change rates from baseline after 1, 4, 8, and 12 months of ROMO treatment, with and without ELD are shown in Figs. 3C and 4C. In the CKD group, the changes were 101, 25, 15, -24% with ELD and 51, 25, -7, -25% without ELD, respectively (Fig. 3C). In the non-CKD group, the corresponding changes were 82, 38, 5, -6% with ELD and 80, 27, -2, -14% without ELD, respectively (Fig. 4C).
In both groups, no significant change from baseline was observed, regardless of ELD administration. Additionally, no significant differences were found between treatments with and without ELD in either group.
Adverse events and new fractures
In the CKD group, there was one fracture (FN fracture) in the ROMO + ELD treatment group and no fractures in the ROMO treatment group. There were no significant differences in fracture incidence between treatment with and without ELD (P=0.090) (Table IV).
In the CKD group, adverse events that led to treatment discontinuation were reported in 1 patient (hyponatremia) who underwent ROMO treatment without ELD. There were no significant differences between treatments with or without ELD (P=0.55). In the non-CKD group, no fractures were observed after treatment with or without ELD.
Adverse events leading to treatment discontinuation were reported in 1 patient (renal dysfunction) receiving treatment with ELD and in another patient (injection site pain) receiving treatment without ELD. There were no significant differences between treatments with and without ELD (P=0.36).
Discussion
In the present study, the safety and efficacy of a 12-month ROMO treatment regimen in Japanese patients with osteoporosis grouped into CKD and non-CKD groups based on their baseline eGFR values (≥60 or <60 ml/min/1.73 m2), were investigated. In addition, the ROMO + ELD treatment with respect to baseline eGFR was evaluated.
At the end of the 12-month ROMO treatment regimen, the LS BMD significantly increased regardless of baseline eGFR. The FN BMD slightly increased in the non-CKD group, whereas it decreased slightly in the CKD group after 12 months of ROMO treatment. Serum PINP levels were significantly elevated after 1 month and significantly decreased after 8 months and 12 months of ROMO treatment in both subgroups. The incidence of new fractures and adverse events was low in both subgroups, and the differences were not statistically significant between the subgroups. There were no significant differences in BMD, fracture incidence, or adverse events between the combination treatment and ROMO monotherapy groups.
In the CKD group, the percentage change in the serum PINP levels and the FN BMD values observed were greater in the combination treatment group than in the ROMO monotherapy. Bone metabolism is essential for maintaining bone tissue homeostasis and function. Disruptions in this balance can lead to osteoporosis, osteoarthritis, bone defects, bone tumors, and other bone diseases (23,24). Osteoporosis is categorized as primary or secondary. Primary osteoporosis results from the natural aging process, whereas secondary osteoporosis is caused by various systemic diseases and organ disfunction, such as CKD and endocrine disorders. Glucocorticoid-induced osteoporosis is the most common form of secondary osteoporosis. Currently, the most widely used drugs for treating osteoporosis include anabolic agents, anti-resorptive agents, and medications with alternative mechanisms of action. If the underlying disease is unrecognized and left untreated, the response of secondary osteoporosis to conventional anti-osteoporotic therapy may be inadequate (25,26). In addition, numerous osteoporosis treatment drugs are associated with undesirable adverse effects or are unsuitable for long-term use. Thus, there is a critical need for the development of targeted molecules capable of safely preserving bone homeostasis. Recent research suggests that gut hormones such as GIP and GLP-1, may influence bone remodeling, with GIP inhibiting bone resorption and GLP-1 promoting bone formation (27). Flavonoids have been attracting attention as potential therapeutic targets (28-33). Recently, Yu et al (29) reported on osteoclast-targeting nanoparticles, named OAPLG, which were developed by integrating oroxylin A, a natural flavonoid, with amorphous calcium carbonate and coating them with glutamic acid hexapeptide-modified phospholipids. These smart nanoparticles can neutralize acid and release oroxylin A in the osteoclast microenvironment, synergistically inhibiting osteoclast formation and activity. This approach effectively reversed systemic bone loss in an ovariectomized mouse model (29).
Mesenchymal stem cells (MSCs) are mesoderm-derived adult stem cells with self-renewal and multilineage differentiation potential, capable of forming osteocytes, chondrocytes, adipocytes, and fibroblasts. They offer clinical advantages due to the ease of their isolation and secretion of growth factors. However, challenges such as low survival rates, immune rejection, and environmental sensitivity limit their direct therapeutic use. Extracellular vesicles (EVs), which are nano-sized vesicles released by cells, play a key role in intercellular communication and immune response (34). MSC-derived EVs (MSC-EVs) mimic MSC functions but are less immunogenic and more stable due to lipid protection. By combining the advantages of MSCs and EVs, MSC-EVs present a promising therapeutic option for bone disorders (35).
The kidneys play a critical role in bone development and metabolism by regulating calcium and phosphate homeostasis and the production of key substances such as 1,25(OH)2D3, klotho, and erythropoietin (36). Renal dysfunction causes phosphate retention, reduces calcitriol production, and leads to hypocalcemia. Reduced 1-α-hydroxylase activity and underexpression of parathyroid calcium-sensing and vitamin D receptors further contribute to low calcitriol levels, stimulating parathyroid hormone (PTH) secretion and resulting in secondary hyperparathyroidism. Excessive PTH levels lead to the release of calcium from bone. The mechanism of action of ELD is poorly characterized; however, ELD has demonstrated the ability to control the migration of osteoclast precursor monocytes and limit osteoclastic bone resorption (37). ROMO is a bone-forming agent that inhibits sclerostin, exerting a dual effect by increasing bone formation and decreasing bone resorption (38). Global sclerostin inhibition is linked to cardiovascular side effects. The β-1,4-N-acetyl-galactosaminyltransferase 3 (B4GALNT3) gene has been identified as a key regulator of circulating sclerostin levels. Recent research has shown that B4GALNT3-mediated glycosylation of sclerostin may be a promising bone-specific osteoporosis target, separating anti-benefits from cardiovascular side effects (39).
The effect of ROMO on bone formation was revealed to be characterized by a rapid increase, which subsequently returns to baseline despite continued administration, whereas the reduction in circulating markers of bone resorption was sustained throughout the 12-month dosing period (38). Unfortunately, in the present study the markers of bone resorption were not assessed, limiting the present analysis to PINP. In the present study, the rate of increase in PINP levels peaked at month 1, followed by a decline below baseline values over time, which is consistent with previous findings (38).
The present study revealed several important findings. First, the study demonstrated that, in actual clinical practice, ROMO is an effective and safe treatment option for patients with osteoporosis and impaired kidney function. The incidence of serious adverse events was similarly low in both eGFR subgroups, which may be pharmacologically plausible given that ROMO is a humanized monoclonal IgG2 antibody with a large molecular size. The glomerular filtration of monoclonal antibodies is limited by the size of the protein molecule; molecules >70 kDa are not filtered in glomeruli (40). Thus, there may have been minimal renal filtration of ROMO (molecular weight, 145 kDa). Therefore, ROMO may be an effective and safe treatment option for patients with CKD.
Second, the combination of active vitamin D analog with ROMO did not significantly affect the rate of increase in BMD with and without CKD. Currently, several studies have reported that combination treatment with active vitamin D and bisphosphonate or denosumab increased BMD gains compared with monotherapy; however, the superiority of combination treatment is controversial (41-43). In regard to the combination treatment of ROMO with active vitamin D analog in previous studies, Kobayakawa et al (21) compared the efficacy of 12-month ROMO in the presence or absence of an active vitamin D analog and reported that such combination treatment may not be essential in terms of BMD improvement in postmenopausal patients with osteoporosis (21). In the course of CKD, there is a slow and progressive reduction in the levels of 1,25-dihydroxyvitamin D as kidney function declines. A 2023 systematic review found that vitamin D receptor activators effectively suppress PTH levels but carry an increased risk of hypercalcemia (36). In particular, ELD slightly increased the risk of hypercalcemia in patients with stage 3B CKD (44). The effects of active vitamin D analog among people with CKD are uncertain. There are no reports published regarding the combination treatment of ROMO and active vitamin D analogs across different levels of renal function. In the present present study, it was revealed that the use of an active vitamin D analog did not significantly influence the increase in BMD, regardless of baseline eGFR.
Third, the results of the present study revealed a greater increase in serum PINP levels and the FN BMD with combination treatment in the CKD group. Additionally, baseline serum PINP levels in the CKD group were higher in the ROMO monotherapy group than in the combination treatment group. Baseline serum PINP levels are reportedly associated with elevated hip bone BMD after ROMO treatment (45). Conversely, in the CKD group, the percentage change in the FN BMD observed in the combination treatment group was greater than that in the ROMO monotherapy group.
There is a well-documented association between an early increase in PINP levels after ROMO induction and ROMO treatment response (46,47). A previous study showed that patients with a greater increase in PINP levels at 1 month had improved BMD gains over 12 months (46).
In the CKD group, the combination treatment group showed substantial increase in serum PINP levels at 1 month. The serum 1,25(OH)2D levels were significantly affected by the degree of renal failure. A reduced renal mass and uremic factors are considered to lower the activity of 25(OH)D3 1-α-hydroxylase. A significant positive correlation between 1,25(OH)2D and estimated creatinine clearance has been reported (48) Therefore, ROMO + ELD treatment may have a greater impact by restoring the active form of vitamin D, which is often depleted in patients with CKD.
These results indicate that ROMO + ELD treatment may be beneficial for patients with an eGFR of <60 ml/min/1.73 m2.
Several limitations of this study should be acknowledged. Firstly, only a small number of patients received combination treatment with ROMO and an active vitamin D analog, which limited the assessment of the efficacy and safety of this combination treatment. In particular, the number of patients with severe renal insufficiency (eGFR ≤29 ml/min/1.73 m2) was extremely limited (ROMO, 5 patients; ROMO + ELD, 1 patient), preventing a detailed subgroup analysis based on renal function from being conducted.
Although it was not possible in this study due to the small sample size, the effectiveness of ROMO + ELD treatment on BMD may potentially be demonstrated by collecting data on detailed renal function parameters such as eGFR ranges of 0-29, 30-59, 60-89, and ≥90 ml/min/1.73 m2.
Secondly, there were significant differences in baseline age between the CKD and non-CKD groups. Notably, changes in bone metabolism associated with aging result in a net bone loss, with some studies indicating a more pronounced relative loss and thinning with age for all trabeculae (49-51). Changes in bone metabolism associated with aging may affect the increase in BMD. Therefore, there is a possibility that the present findings may change when comparing individuals with different kidney functions within the same age group. Thirdly, the effects of prior osteoporosis treatments were not considered in the present study.
Fourthly, the present study did not consider populations with conditions affecting vitamin D metabolism, such as liver disease. Cirrhosis leads to vitamin D deficiency due to impaired metabolism and malabsorption, contributing to osteoporosis and osteomalacia. Liver disease disrupts calcium and vitamin D balance, reducing bone formation and increasing bone loss, with alcohol-related liver disease and primary biliary cirrhosis further elevating the risk of osteoporosis (52,53). In such populations, combining ROMO with ELD may enhance BMD more effectively than ROMO monotherapy. Thus, additional large-scale randomized controlled trials are required to address these limitations.
Lastly, only serum PINP levels were evaluated among the various bone turnover markers. There is a possibility that other bone turnover markers are more strongly associated with the BMD response.
In summary, the results of the present study revealed that ROMO was an effective and safe treatment option for osteoporosis regardless of renal function. Comination treatment with ROMO and ELD may be beneficial for patients with an eGFR of <60 ml/min/1.73 m2.
