Comparative risk/benefit profile of biosimilar and originator erythropoiesis-stimulating agents (ESAs): data from an Italian observational study in nephrology

Purpose: The aim of this multicenter prospective study was to evaluate efficacy and safety of biosimilar erythropoiesis-stimulating agents (ESAs) vs originator, based on data from clinical practice in patients with chronic kidney disease (CKD). Methods: We collected data of the patients with diagnosis of CKD on conservative treatment from nine Italian structures. Patients were enrolled applying different exclusion criteria, and various individual parameters were registered at the beginning for descriptive analysis. Patients were treated with epoetin alfa, beta, and darbepoetin as originator and epoetin zeta as biosimilar. Hemoglobin levels have been analyzed at baseline and after 3, 6, and 12 months. Descriptive statistics were used to analyze the results. Results: At baseline, 47 patients were in the biosimilar group and 57 in the originator; the basal level of hemoglobin was similar between the groups (mean Hb 9.4 and 9.3 g/dL, respectively). Median age, weight, and comorbidities were almost comparable. After 3 months, 44 patients remained in the biosimilar group and 48 in the originator; hemoglobin increase was significantly greater in patients treated with biosimilar [absolute increase 1.6 vs 1.0 g/dL, p < 0.001]. After 6 and 12 months, number of patients fall furthermore. Hemoglobin levels increased more in the biosimilar group after 6 months (2.1 vs 1.1 g/dL, p < 0.001) and 12 months (2.0 vs 1.0 g/dL, p < 0.001). Conclusions: Biosimilar ESAs have similar risk/benefit profile compared to originators. Our data are in agreement with relevant scientific literature and, on the other hand, they are in contrast with common thought that considers biosimilar less efficacious and less safe than originators

Use of aliskiren in a 'real-life' model of hypertension management: analysis of national Web-based drug-monitoring system in Italy.

Introduction In Italy, prescriptions of the direct renin inhibitor aliskiren (aliskiren) to high-risk hypertensive patients must be electronically filled by specialized physicians only when at least two antihypertensive drug classes (independently of the dosages), fails to normalize blood pressure (BP) levels. Aim To analyze the effects of the addition of aliskiren 150-300 mg daily to antihypertensive therapy in a population of high cardiovascular risk hypertensive patients with uncontrolled BP levels. Methods Clinical data were derived from patients included in the national Web-based drug-monitoring system. Followup visits were required for measuring BP levels, and collecting data on drug safety and tolerability. Results Between March 2009 and February 2010, aliskiren was prescribed by 6464 specialized physicians to 11 511 treated, uncontrolled hypertensive patients (47.6% women, aged 68.0 +/- 11.1 years, BMI 28.4 +/- 4.9 kg/m(2)) with organ damage or comorbidities. During 6-month observation, only a few drug-related side-effects were reported (n=33). At the entry and 1-month follow-up visits (n=8197; 70.6%), BP levels were 158.9 +/- 16.8 and 142.1 +/- 15.2 mmHg for SBP and 90.8 +/- 9.6 and 83.1 +/- 8.5 mmHg for DBP, respectively. At 6-month (n=4907; 42.3%), SBP and DBP levels were 137.9 +/- 13.9 and 81.3 +/- 8.0 mmHg, respectively. A consistent reduction in the use of all classes of concomitant antihypertensive drugs was recorded. Conclusion Although data derived from national registries need to be interpreted with caution, the Italian Web-based drug-monitoring system provided information on 'real-life' use of aliskiren in hypertension. In this uncontrolled, high-risk treated hypertensive population, SBP and DBP levels recorded during treatment with aliskiren were consistently lower than those recorded at entry visits in a context of a very low rate of reported side-effects.

Governance of Slow-developing Catastrophic Risks: Fostering Complex Adaptive Systems and Resilience Thinking

Cisplatin chemotherapy and surgery are effective treatments for children with standard-risk hepatoblastoma but may cause considerable and irreversible hearing loss. This trial compared cisplatin with cisplatin plus delayed administration of sodium thiosulfate, aiming to reduce the incidence and severity of cisplatin-related ototoxic effects without jeopardizing overall and event-free survival

Lenalidomide treatment of myelodysplastic syndromes with chromosome 5q deletion: Results from the National Registry of the Italian Drug Agency

Objective: The most typical cytogenetic aberration in myelodysplastic syndromes is del(5q), which, when isolated, is associated with refractory anaemia and good prognosis. Based on high rates of erythroid response and transfusion independence, Lenalidomide (LEN) became the standard treatment. This multi-centre study was designed to supplement Italian Registry data on LEN by addressing prescription, administration appropriateness, haematological and cytogenetic responses and disease evolution. Methods: MORE study was an observational, non-interventional, multi-centre, retrospective and prospective study. Cases were recruited from 45 Haematological Centres throughout Italy. Data were collected from the Italian National Registry for Lenalidomide administration and supplemented by a MORE data form. Results: Data from 190/213 patients were analysed. In all, 149 had been diagnosed by conventional cytogenetics (GROUP A) and 41 only by FISH (GROUP B). Overall erythroid response was obtained in 92.8% of cases. Overall cytogenetic remission was achieved in 22.6% of cases. Disease progression occurred in 15.6% of cases. Clonal cytogenetic evolution characterised progression to AML but not to higher risk MDS. Conclusions: Erythroid response to Lenalidomide was similar in MDS with isolated del(5q) and with del(5q) plus one anomaly. Progression to AML or higher risk MDS showed different cytogenetic features
