Abstract
Novel treatments in multiple myeloma (MM) could influence the incidence of skeletal-related events (SREs). We aimed to examine the incidence of SRE and the preventive use of osteoclast inhibitors (OIs) in a cohort of MM patients in the era of modern treatment. In this real-world retrospective study, we included 199 patients with a diagnosis of MM between January 1, 2010, and December 31, 2019, with follow-up at St. Olavs University Hospital. Data was extracted from The Myeloma Registry of Central Norway. SREs occurred in 46% of patients at baseline and 55.8% during follow-up. Excluding baseline SREs, the incidence rate was 29 (95% confidence interval: 26-33) per 100 person years. 48% experienced > 1 SRE. The incidence of SREs was highest at baseline followed by a gradual increase in each subsequent line of treatment. The first two years after diagnosis 80% received bisphosphonates (BPs). The proportion of recommended dosage was 46%. Only two cases (1.2%) of symptomatic hypocalcemia and one case (0.6%) of osteonecrosis of the jaw were identified. SREs are still a common problem in an era of novel treatment. Cumulative dosage of BPs was lower than recommended, and treatment with BPs was safe in this population.

External Validation and Update of the Risk Prediction Model for Denosumab-Induced Hypocalcemia Developed From a Hospital-Based Administrative Database. JCO Clin Cancer Inform 2024; 8:e2400078. [PMID: 39008783 PMCID: PMC11371100 DOI: 10.1200/cci.24.00078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2024] [Revised: 04/23/2024] [Accepted: 05/10/2024] [Indexed: 07/17/2024] Open
Abstract
PURPOSE Denosumab is used to treat patients with bone metastasis from solid tumors, but sometimes causes severe hypocalcemia, so careful clinical management is important. This study aims to externally validate our previously developed risk prediction model for denosumab-induced hypocalcemia by using data from two facilities with different characteristics in Japan and to develop an updated model with improved performance and generalizability. METHODS In the external validation, retrospective data of Kameda General Hospital (KGH) and Miyagi Cancer Center (MCC) between June 2013 and June 2022 were used and receiver operating characteristic (ROC)-AUC was mainly evaluated. A scoring-based updated model was developed using the same data set from a hospital-based administrative database as previously employed. Selection of variables related to prediction of hypocalcemia was based on the results of external validation. RESULTS For the external validation, data from 235 KGH patients and 224 MCC patients were collected. ROC-AUC values in the original model were 0.879 and 0.774, respectively. The updated model consisting of clinical laboratory tests (calcium, albumin, and alkaline phosphatase) afforded similar ROC-AUC values in the two facilities (KGH, 0.837; MCC, 0.856). CONCLUSION We developed an updated risk prediction model for denosumab-induced hypocalcemia with small interfacility differences. Our results indicate the importance of using data from plural facilities with different characteristics in the external validation of generalized prediction models and may be generally relevant to the clinical application of risk prediction models. Our findings are expected to contribute to improved management of bone metastasis treatment.

Severe hypocalcemia after denosumab treatment leading to refractory ventricular tachycardia and veno-arterial extracorporeal membrane oxygenation support: a case report. Int J Emerg Med 2023; 16:52. [PMID: 37635211 PMCID: PMC10463425 DOI: 10.1186/s12245-023-00529-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 08/20/2023] [Indexed: 08/29/2023] Open
Abstract
BACKGROUND Severe hypocalcemia may lead to life-threatening arrhythmias. Denosumab is an effective treatment for osteoporosis that allows long intervals between doses. However, there is a risk of hypocalcemia in some patients. Due to the long half-life of denosumab, emergency physicians caring for patients presenting with symptoms of hypocalcemia may not be aware of the medication, and adverse effects may last longer. CASE PRESENTATION A 55-year-old woman with a history of systemic lupus erythematosus (SLE) and anxiety disorder called for an ambulance for symptoms of hyperventilation and muscle cramps. After evaluation at the local hospital, she developed pulseless ventricular tachycardia and was resuscitated by defibrillation by the hospital staff. After conversion to sinus rhythm, she was transported to a tertiary center. Upon arrival, pulseless ventricular tachycardia occurred again, and veno-arterial extracorporeal membrane oxygenation (ECMO) and intra-aortic balloon pumping (IABP) were implemented. Laboratory results showed severe hypocalcemia (corrected calcium level of 5.3 mg/dL) whereupon intravenous calcium supplementation was started. She had received the first dose of denosumab (60 mg) by subcutaneous injection 24 days prior to hospitalization. She was eventually weaned from ECMO and IABP support. CONCLUSION Cardiac arrest due to hypocalcemia is relatively rare but can be fatal. In the present case, hyperventilation may have acutely exacerbated pre-existing hypocalcemia, leading to ventricular tachycardia. The patient had a slightly decreased serum calcium level prior to denosumab. Close monitoring may be preferable after the primary dose of denosumab in selected patients. Emergency physicians caring for patients who may be suffering from symptoms/signs of hypocalcemia must be mindful of medications that have long half-lives and affect electrolyte balance when treating fatal arrhythmia due to hypocalcemia.

Abstract
INTRODUCTION Denosumab (Xgeva®) and zoledronic acid (Zometa®) are widely utilized for prevention of skeletal related events (SREs) in oncology patients. Drug costs, renal function, ease and logistics of administration, and adverse effect profile are factors frequently considered by patients and/or providers when selecting an optimal agent. Given the significantly higher drug cost of denosumab compared to zoledronic acid, an evaluation of our institution's denosumab use and investigation into opportunities to shift denosumab administrations to zoledronic acid and/or to lower cost sites-of-care was warranted. METHODS A single-center, multi-site, retrospective, observational analysis of the electronic medical record (EMR) was conducted for adult oncology patients who received denosumab 120 mg for prevention of SREs from October 1st, 2018 to September 30th, 2019 at three institutions within our health system. Additional information was collected to characterize the patient population based on cancer diagnosis, renal function, and concomitant calcium and vitamin D supplementation. Our primary objective was to evaluate if the use of denosumab met current formulary restrictions of the health system. RESULTS In total, 304 adult oncology patients received 1411 doses of denosumab for the prevention of SREs. The majority of reviewed patients had a primary oncology diagnosis of breast (35%) or lung (24%) cancer. Of the patients who received denosumab, 278 (93%) met the health system's current formulary restrictions. The majority of patients who did not meet formulary restrictions were those with multiple myeloma (MM) (20/22; 91%). Of the 304 patients reviewed, 70 had the appropriate parameters in the EMR to calculate creatinine clearance (CrCl) using Cockcroft-Gault Equation. Of those 70 patients, 59 (84%) would have been eligible to receive zoledronic acid instead of denosumab given that their CrCl >30 mL/min with no documented intolerance to bisphosphonates. Concurrent use of calcium and vitamin D is recommended when using denosumab. Based on the most recent prior to admission (PTA) medication list obtained from the 304 patients evaluated, 222 (73%) had both calcium and vitamin D listed as "taking". CONCLUSIONS Within our health system, denosumab is restricted to those who meet formulary restrictions. Additional education is recommended to help limit the use of denosumab, specifically in MM, to reduce drug costs when zoledronic acid is also an appropriate first-line agent.

Abstract
Denosumab is a humanized monoclonal antibody that binds RANKL to inhibit osteoclast activity. It is indicated for the prevention of skeletal-related events (SRE) in patients with solid tumors who have bone metastasis and in patients with multiple myeloma. Hypocalcemia is one of the known side effects of denosumab, which can be prevented with calcium supplementation. We present a case of a 72-year-old male with diagnosed metastatic prostate cancer who had received one dose of denosumab 10 days prior to presentation with fatigue, insomnia, and somnolence. His labs showed severe (Grade 4) hypocalcemia, which improved with intravenous calcium supplementation. This case highlights a known but life-threatening side effect of denosumab and the potential need for prolonged calcium monitoring in patients placed on the drug.

Abstract
INTRODUCTION Denosumab is a human monoclonal antibody inhibiting the receptor activator of nuclear factor kappa-B ligand (RANKL). Initially approved as antiosteοporotic agent, denosumab is being currently pursued as a candidate for drug repurposing in oncology, especially breast cancer. AREAS COVERED The present review provides an overview of the therapeutic potential of denosumab in breast cancer beyond prevention of skeletal-related events (SREs), with focus on prevention of carcinogenesis in BRCA mutation carriers and on adjuvant treatment in early breast cancer patients. Study search was conducted on the following electronic databases: PubMed, Google scholar, Scopus.com, ClinicalTrials.gov, and European Union Clinical Trials Register from 2008 until June 2020. EXPERT OPINION Nonclinical data have established links between RANKL signaling and breast cancer initiation and progression, rationalizing exploring the potential bone-independent anticancer role of denosumab beyond SREs prevention. Preclinical and preliminary clinical data show that denosumab may inhibit carcinogenesis in BRCA mutation carriers. Denosumab adjuvant in early breast cancer has been shown, though inconsistently, to provide a disease-free survival benefit for a subgroup of patients. Despite promising results, the incorporation of denosumab in preventive and therapeutic protocols of breast cancer beyond prevention of SREs cannot be endorsed until further research consolidates its efficacy.

Abstract
INTRODUCTION Repurposing denosumab in lung cancer therapeutics capitalizes on its well-established role in preventing the skeletal related events (SREs) and its emerging, yet elusive, bone-independent role, assigned to inhibit the contribution of RANKL to cancer initiation and progression. AREAS COVERED The present review presents the available preclinical and clinical data indicating that denosumab may provide survival benefit to lung cancer patients beyond the counteraction of SREs. EXPERT OPINION Despite the preliminary data heralding the potential of denosumab to increase overall survival in lung cancer, the embracement of this strategy in clinical practice cannot be advocated until large randomized clinical trials consolidate its safety and efficacy. Given the improvement of lung cancer prognosis ascribed to revolutionary targeted treatment agents, the possibility of denosumab-related increased risk of second primary malignancies merits further evaluation. Many challenges in endorsing denosumab as a strategy to treat lung cancer beyond SREs prevention are pending counteraction, including: (i) patient selection guided by validated predictive and prognostic biomarkers; (ii) assessment of long-term outcomes; (iii) evaluation of benefit-risk ratio; (iv) translational research; (v) combination of denosumab with other targeted therapies; (vi) integration of genomic biomarkers, immune-related biomarkers, and biomarkers of active RANKL pathway to guide the decision-making process.

Abstract
OBJECTIVES Denosumab is often used in men with advanced prostate cancer to prevent skeletal-related events, but can be associated with severe hypocalcaemia. Our objective was to review the pathophysiology, identify risk factors and provide recommendations for prevention and management of denosumab-associated hypocalcaemia. DESIGN We reviewed the literature regarding denosumab-associated severe hypocalcaemia, defined as necessitating hospitalization for intravenous calcium treatment, in the context of prostate cancer. PATIENTS Men with prostate cancer with severe denosumab-associated hypocalcemia. RESULTS We identified 20 men with prostate cancer with severe denosumab-associated hypocalcemia, including the present case. Median age (range) was 70 years (45-86). All had skeletal metastases and presented with symptomatic hypocalcemia 16 days (4-35) after the initial (n = 18) or second (n = 2) denosumab treatment, with a serum total calcium of 1.36 mmol/L (1.13-1.91). The key risk factor was presence of active osteoblastic metastases, evidenced by elevated serum alkaline phosphatase, 838 U/L (58-2620) and supportive imaging. Other risk factors reported in some men included vitamin D deficiency (<50 nmol/L), 25-OH vitamin D 44 nmol/L (22-81), renal impairment, serum creatinine 103 μmol/L (62-1131) and hypomagnesaemia, 0.82 mmol/L (0.29-1.20). Men received intravenous calcium infusions for 16 days (1-90), and median total intravenous elemental calcium requirements were 3.17 g (0.47-26.65). CONCLUSIONS Denosumab treatment in men with metastatic prostate cancer can be associated with life-threatening hypocalcaemia requiring prolonged hospitalization for intravenous calcium treatment. Modifiable risk factors should be corrected before denosumab administration. In men with active osteoblastic metastases, consideration should be given to delay denosumab treatment until underlying disease activity is controlled, and/or be administered with close monitoring and proactive treatment with calcium and calcitriol.

Abstract
Objective Denosumab is a monoclonal antibody commonly used for the prevention of skeletal-related events in patients with bone metastases from solid tumors. Hypocalcemia is a known adverse effect with denosumab, and we present an unusual case where 2 hypocalcemic events occurred after 1 denosumab treatment. Methods A 76-year-old man recently diagnosed with prostate cancer with bone metastasis was given 120 mg denosumab subcutaneously due to extensive bone disease. Results The patient experienced denosumab-induced hypocalcemia induced by a single denosumab dose which was resolved after 14 days of multiple doses of intravenous calcium gluconate and oral calcium and vitamin D replacement. However, the patient returned with acute kidney injury and severe hypocalcemia (corrected calcium of 6.9 mg/dL) without any additional dose of denosumab. The recovery following the second episode of hypocalcemia was much longer than the initial episode in this patient. Conclusion To our knowledge, this is the first reported case of an additional episode of hypocalcemia following a single denosumab dose. This case highlights the importance of close monitoring of renal function and serum electrolytes following the resolution of denosumab-induced hypocalcemia.

Abstract
PURPOSE OF REVIEW Patients with chronic kidney disease have a high risk of fractures and no established treatments that have been shown to prevent the bone disease. The physiology of renal osteodystrophy is complex and recently more factors have been found that complicate the mineral metabolism. The recognition that vascular calcifications are related to bone disease has made treatment even more challenging. RECENT FINDINGS The most exciting new findings relate to the signaling pathways that are seen in kidney disease and how they cause abnormalities in bone physiology. In particular, wnt and activin signaling pathways are seen early in the course of renal disease. The bones react by increasing FGF-23, which targets both renal phosphate secretion and a variety of other systemic effects. Secreted klotho is another newly described hormone with effects on several systems.Clinical studies have focused on treatments for hyperparathyroidism and phosphate, and frustrating limitations of the treatments used for ordinary osteoporosis. SUMMARY Treatment of bone disease in patients with chronic kidney disease is challenging, and understanding the physiological pathways could lead to novel therapies.

Abstract
Introduction: The introduction of monoclonal antibodies (moAbs) into clinical practice revolutionized the treatment strategies in several solid tumors. These agents differ from cytotoxic chemotherapy for their mechanism of action and toxicity. By targeting specific antigens present on healthy cells and modulating immune system activity, these biological drugs are able to generate a wide spectrum of peculiar adverse events that can negatively impact on patients' quality of life. Areas covered: In this review, the main side effects associated with the use of moAbs have been described to show their incidence and current management strategies, which may drive clinicians in their daily practice. Expert opinion: The majority of these drugs represents an example of successful innovation, since they are able to induce a significant improvement of patients' survival and quality of life without any increase in related side effects as compared to standard cancer treatments. For this reason, they have become new milestones in personalized therapy for different non-hematological malignancies. With the increasing use of moAbs in treatment regimens, it is strongly recommended that clinicians are knowledgeable about the side effects associated with these agents, their management and monitoring, to optimize the clinical treatment of cancer patients.

Abstract
Background Most patients with advanced prostate cancer develop bone metastases, which often result in painful and debilitating skeletal-related events. Inhibitors of bone resorption, such as bisphosphonates and denosumab, can each reduce the incidence of skeletal-related events and delay the progression of bone pain. However, these agents are associated with an increased risk of hypocalcaemia, which, although often mild and transient, can be serious and life-threatening. Here we provide practical advice on managing the risk of hypocalcaemia in patients with advanced prostate cancer who are receiving treatment with bone resorption inhibitors. Relevant references for this review were identified through searches of PubMed with the search terms ‘prostate cancer’, ‘bone-targeted agents’, ‘anti-resorptive agents’, ‘bisphosphonates’, ‘zoledronic acid’, ‘denosumab’, ‘hypocalcaemia’, and ‘hypocalcemia’. Additional references were suggested by the authors. Main text Among patients with advanced cancer receiving a bisphosphonate or denosumab, hypocalcaemia occurs most frequently in those with prostate cancer, although it can occur in patients with any tumour type. Consistent with its greater ability to inhibit bone resorption, denosumab has shown superiority in the prevention of skeletal-related events in patients with bone metastases from solid tumours. Consequently, denosumab is more likely to induce hypocalcaemia than the bisphosphonates. Likewise, various bisphosphonates have differing potencies for the inhibition of bone resorption, and thus the risk of hypocalcaemia varies between different bisphosphonates. Other risk factors for the development of hypocalcaemia include the presence of osteoblastic metastases, vitamin D deficiency, and renal insufficiency. Hypocalcaemia can lead to treatment interruption, but it is both preventable and manageable. Serum calcium concentrations should be measured, and any pre-existing hypocalcaemia should be corrected, before starting treatment with inhibitors of bone resorption. Once treatment has started, concomitant administration of calcium and vitamin D supplements is essential. Calcium concentrations should be monitored during treatment with bisphosphonates or denosumab, particularly in patients at high risk of hypocalcaemia. If hypocalcaemia is diagnosed, patients should receive treatment with calcium and vitamin D. Conclusion With preventative strategies and treatment, patients with prostate cancer who are at risk of, or who develop, hypocalcaemia should be able to continue to benefit from treatment with bisphosphonates or denosumab.

Abstract
Bone is a common site for malignant involvement, either as a site of metastasis, especially in breast or prostate cancer, or as a defining characteristic of the disease, as in multiple myeloma. Bone disease is a major source of morbidity, and half of patients with bone involvement develop skeletal-related events such as pathological fractures or cord compression requiring surgery and/or radiation. Skeletal involvement also increases mortality, as pathologic fractures increase the risk of dying by 20-40%. Osteoclast inhibition with bisphosphonates such as zoledronic acid and recently denosumab has been a significant improvement for bone disease. This review will focus on denosumab in the treatment of bone metastases and highlight the recent findings in multiple myeloma.

Abstract
Effective treatments for osteoporosis remain fairly elusive; however, studies have reported that antioxidants may aid in the maintenance of reactive oxygen species at a favorable level, in order to prevent osteoporosis. Gallic acid (GA) and its derivatives are potent antioxidative and anti-inflammatory agents that affect several biochemical and pharmacological pathways; however, GA is slightly cytotoxic and suppresses cell proliferation. The present study modified GA by the introduction of sulfonamide, in order to obtain a novel compound known as JEZ-C, and investigated its effects on osteoblasts by measuring cell proliferation, viability, morphology, alkaline phosphatase (ALP) activity, and the expression of relevant osteoblast markers. Results indicated that JEZ-C may effectively promote osteoblast growth. JEZ-C increased ALP activity, upregulated the expression of osteogenic-related genes, including runt-related transcription factor 2, bone sialoprotein, osteocalcin and alpha-1 type I collagen, thus indicating that JEZ-C enhances bone matrix production and mineralization. The recommended range of JEZ-C concentration is between 6.25×10−3 and 6.25×10−1 µg/ml, within which cell growth was promoted compared with the control. Specifically, treatment with 6.25×10−2 µg/ml JEZ-C is ideal. These findings may represent a novel approach to cell-based therapy for the treatment of osteoporosis.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a chronic inflammatory disorder characterized by focal pathologic bone resorption due to excessive activity of osteoclasts (OC). Receptor activator of nuclear factor kappa B ligand (RANKL) is essential for the proliferation, differentiation, and survival of OC. Denosumab (DMab) is a humanized monoclonal antibody that binds to RANKL with high affinity and blocks its subsequent association with its receptor RANK on the surface of OC precursors. Area covered: The authors review the molecular and cellular mechanisms underlying therapeutic applications of DMab, provide recent highlights on pharmacology, efficacy and safety of DMab, and discuss the potential of DMab as a novel therapeutic option for the treatment of rheumatoid arthritis. Expert opinion: Clinical results suggest that DMab is efficient both in systemic and articular bone loss in RA with limited side effects. Diminished bone erosion activity was also noted in RA patients on corticosteroids and bisphosphonates. Combination of DMab with an anti-TNF agent was not associated with increased infection rates. Collectively, these data indicate that DMab, in combination with methotrexate and possibly other conventional synthetic Disease Modifying Anti-Rheumatic Drugs (csDMARDs), is an effective, safe and cost-effective option for the treatment of RA.
