Real-World Evaluation of Calcimimetics for the Treatment of Secondary Hyperparathyroidism in Chronic Kidney Disease, in an Italian Clinical Setting.

ABSTRACT: This Italian real-world data analysis evaluated the pharmaco-utilization of calcimimetics, cinacalcet or etelcalcetide, and the economic burden of secondary hyperparathyroidism (SHPT) in chronic kidney disease (CKD) patients. From 1 January 2010 to 30 June 2020, adult patients with: (i) ≥1 prescription of etelcalcetide or cinacalcet, (ii) ≥3 hemodialysis/week, and (iii) without parathyroidectomy, were included. Based on the drug firstly prescribed, patients were allocated into etelcalcetide- and cinacalcet-treated cohorts, and the propensity score matching (PSM) methodology was applied to abate potential cohorts' unbalances. Overall, 1752 cinacalcet- and 527 etelcalcetide-treated patients were enrolled. In cinacalcet- and etelcalcetide-treated patients, respectively, the most frequent comorbidities were hypertension (75.3% and 74.4%), diabetes mellitus (21.0% and 21.3%), and cardiovascular disease (18.1% and 13.3%, p < 0.01). In covariate-balanced cohorts, the treatment adherence and persistence rates were significantly higher in the etelcalcetide-treated (80.1% and 62.7%, respectively) vs. cinacalcet-treated cohort (62.3% and 54.7%, respectively). After PSM, the total costs for the management of cinacalcet- and etelcalcetide-treated patients, respectively, averaged EUR 23,480 and EUR 22,958, with the disease-specific drug costs (EUR 2629 vs. EUR 2355, p < 0.05) and disease-specific hospitalization costs (EUR 1241 vs. EUR 855) in cinacalcet- and etelcalcetide-treated patients. These results showed that, in etelcalcetide-treated patients, a higher treatment adherence and persistence was found, with disease-specific costs savings, especially those related to drugs and hospitalizations.

Project description:BackgroundPazopanib is part of the therapeutic armamentarium for the treatment of patients with advanced non-adipocytic soft tissue sarcomas (STS) who have received prior chemotherapy, but its optimal use in STS histologies is still left to be further defined.Design and methodsData on STS patients treated with pazopanib in Italy have been prospectively collected from July 2013 to December 2019 through a drug monitoring registry managed by the Italian Medicines Agency (AIFA). This nationwide observational cohort study included patients with advanced STS who received pazopanib. Clinicians were mandatorily requested to fill in the AIFA monitoring registry in order to prescribe pazopanib. Patients were recorded on the basis of their clinical characteristics, histological subtype captured at the time of treatment start, and clinical outcome. Primary outcome was time to treatment discontinuation (TTD). Secondary outcomes recorded were frequency of dose reduction and time to first dose reduction.ResultsWe analyzed data from 1964 sarcoma patients. The most represented histological subtypes were leiomyosarcoma (44.7%), undifferentiated sarcomas/not otherwise specified (11.5%), and synovial sarcoma (8.1%). Overall, the median TTD was 106 days. The variables significantly associated to shorter TTD were Eastern Cooperative Oncology Group performance status (1-2 versus 0), the number of previous lines of treatment (2-4 versus 0-1) and prescribed dose (200 mg or 400 mg versus 800 mg, all once daily). Among the most represented (>20 patients) histological subtypes, we also observed longer TTD in patients with histological diagnosis of malignant solitary fibrous tumor if compared with undifferentiated sarcoma not otherwise specified.ConclusionsIn this nationwide observational real-world study, the outcomes are similar to those reported in the pivotal trial (PALETTE study). Our study includes a significant number of patients with rare/ultra-rare sarcoma subtypes and underlines possible differences in treatment duration among these histologies.

Project description:IntroductionSecondary hyperparathyroidism (SHPT) is a common and serious complication of chronic kidney disease (CKD). Elucidating the metabolic characteristics of SHPT may provide a new theoretical basis for its prevention and treatment. This study aimed to perform a metabolomic analysis of SHPT in patients with CKD stages 3-5 not receiving dialysis.MethodsA total of 76 patients with CKD, 85 patients with CKD-SHPT, and 67 healthy controls were enrolled in this study. CKD was diagnosed according to the criteria specified in the Kidney Disease Improving Global Outcomes 2012 guidelines. SHPT was diagnosed by experienced clinicians according to the Renal Disease Outcomes Quality Initiative Clinical Practice Guidelines. Serum renal function markers and the lipid profile were analyzed. Untargeted ultra performance liquid chromatography-tandem mass spectrometry was used to analyze the serum metabolites of patients with CKD and SHPT. Multivariate analysis of the data was performed using principal component analysis and partial least square discriminant analysis. Serum differential metabolites were identified and further characterized using databases. Pathway enrichment analysis was performed using the Kyoto Encyclopedia of Genes and Genomes database. Correlations between differential metabolites and clinical parameters were determined using the Spearman correlation.ResultsThe serum metabolomic profiles of patients with CKD with and without SHPT differed significantly. Differential metabolites were mainly enriched in the top four Kyoto Encyclopedia of Genes and Genomes pathways: phenylalanine, tyrosine, and tryptophan biosynthesis; sphingolipid metabolism; glycerophospholipid metabolism; and phenylalanine metabolism. In total, 31 differential metabolites were identified; of these, L-tryptophan and (R)-(+)-1-phenylethylamine were decreased, while other amino acids and their derivatives, uremia toxins, carnitine, and lipids, were increased significantly in patients with SHPT compared to those without. The 14 lipid metabolites were positively correlated with levels of Urea, serum creatinine, cystatin C, and triglycerides and negatively correlated with the estimated glomerular filtration rate and levels of total and high- and low-density lipoprotein cholesterol.DiscussionDisturbed amino acid and lipid metabolism were more apparent in patients with SHPT than in those without. This metabolomic profile of SHPT may provide a therapeutic foundation for its future clinical management.
