BiOsimilaRs in the management of anaemia secondary to chemotherapy in HaEmatology and Oncology: results of the ORHEO observational study.

ABSTRACT: The approval of epoetin biosimilars in the European Union requires extensive scientific evaluation and stringent regulatory procedures, including post-marketing studies. The ORHEO (place of biOsimilaRs in the therapeutic management of anaemia secondary to chemotherapy in HaEmatology and Oncology) study was an observational, longitudinal, multicentre study performed in France to evaluate the efficacy and safety of biosimilar epoetins for the treatment of chemotherapy-induced anaemia (CIA) in the clinical setting.Patients >18 years with CIA (haemoglobin [Hb] <11 g/dL) in association with solid tumours, lymphoma or myeloma and eligible for treatment with an epoetin biosimilar were included in this study. Patient characteristics were recorded at baseline along with anaemia-related information, such as observed and target Hb (as chosen by the treating clinician), brand and dose of epoetin biosimilar prescribed, and details of any other treatments. Patients were then followed-up at 3 and 6 months. The primary endpoint was Hb response (defined as Hb reaching ?10 g/dL, an increase of Hb ?1 g/dL since inclusion visit or reaching physician-defined target Hb, with no blood transfusions in the 3 weeks prior to measurement). Other endpoints included adverse events, achievement of target Hb and associated treatments.Overall, 2333 patients >18 years (mean age 66.5 years) with CIA (haemoglobin [Hb] <11 g/dL) in association with solid tumours, lymphoma or myeloma and eligible for biosimilar epoetin treatment were included. 99.9% of patients received epoetin zeta (median dose 30,000 IU/week). Mean baseline Hb was 9.61 g/dL, with 35.6% of patients having moderate anaemia (Hb 8-9.5 g/dL). Hb response was achieved in 81.6% and 86.5% of patients at 3 and 6 months, respectively. Overall mean change in Hb level was 1.52 ± 1.61 and 1.72 ± 1.61 g/dL at 3 and 6 months, respectively. Transfusion and thromboembolic event rates were 9.4% and 2.4% at 3 months, and 5.8% and 1.5% at 6 months, respectively.Epoetin zeta was effective and well tolerated in the management of CIA in patients with solid tumours, lymphoma and myeloma.NCT02140736 (date of registration: 14 May 2014).

Project description:IntroductionAURIGA is the largest real-world study to date to evaluate intravitreal aflibercept (IVT-AFL) treatment of diabetic macular edema or macular edema secondary to retinal vein occlusion (RVO) in routine clinical practice. Here, we report the 24-month outcomes in the RVO cohort from France, Germany, Italy, and Taiwan.MethodsAURIGA (NCT03161912) was a prospective observational study. Eligible patients with RVO were enrolled for whom the decision to treat with IVT-AFL had already been made by the attending physician. Patients were treated with IVT-AFL for up to 24 months at physician discretion according to local practice. The primary endpoint was mean change in visual acuity (VA; Early Treatment Diabetic Retinopathy Study [ETDRS] letters) from baseline to month (M) 12. All statistical analyses were descriptive.ResultsIn 554 treatment-naïve and 65 previously treated patients with RVO, the respective mean (95% confidence interval) change in VA from baseline was + 12.5 (10.8, 14.3) and + 7.9 (3.3, 12.6) letters by M12 and + 11.4 (9.4, 13.3) and + 4.4 (- 0.6, 9.5) letters by M24 (baseline mean ± standard deviation: 51.0 ± 21.9 and 51.9 ± 20.4 letters); 44.0% of treatment-naïve and 27.9% of previously treated patients reported ≥ 15-letter gains by M24. By M24, the mean change in central retinal thickness from baseline was - 247 (- 267, - 227) µm in treatment-naïve patients and - 147 (- 192, - 102) µm in previously treated patients. From baseline to M6, M12, and M24, treatment-naïve patients received a total of 4.0 ± 1.3, 5.5 ± 2.5, and 6.9 ± 4.2 injections, respectively, and previously treated patients received 3.8 ± 1.5, 5.0 ± 2.2, and 6.3 ± 3.7 injections, respectively. The safety profile of IVT-AFL was consistent with that of previous studies.ConclusionsIn AURIGA, patients with RVO experienced clinically relevant functional and anatomic improvements following IVT-AFL treatment in routine clinical practice. These improvements were largely maintained in treatment-naïve patients over the 24-month study despite the decreasing treatment frequency, suggesting long-term durability of IVT-AFL treatment outcomes.

Project description:INTRODUCTION:Preoperative anaemia is linked to poor postsurgical outcome, longer hospital stays, greater risk of complications and mortality. Currently in the UK, some sites have developed anaemia clinics or pathways that use intravenous iron to correct iron deficiency anaemia prior to surgery as their standard of care. Although intravenous iron has been observed to be effective in a variety of patient settings, there is insufficient evidence in its use in cardiac and vascular patients. The aim of this study is to observe the impact and effect of anaemia and its management in patients undergoing cardiac and vascular surgery. In addition, the UK Cardiac and Vascular Surgery Interventional Anaemia Response (CAVIAR) Study is also a feasibility study with the aim to establish anaemia management pathways in the preoperative setting to inform the design of future randomised controlled trials. METHODS AND ANALYSIS:The UK CAVIAR Study is a multicentre, stepped, observational study, in patients awaiting major cardiac or vascular surgery. We will be examining different haematological variables (especially hepcidin), functional capacity and patient outcome. Patients will be compared based on their anaemia status, whether they received intravenous iron in accordance to their hospital's preoperative pathway, and their disease group. The primary outcomes are the change in haemoglobin levels from baseline (before treatment) to before surgery; and the number of successful patients recruited and consented (feasibility). The secondary outcomes will include changes in biomarkers of iron deficiency, length of stay, quality of life and postoperative recovery. ETHICS AND DISSEMINATION:The study protocol was approved by the London-Westminster Research Ethics Committee (15/LO/1569, 27 November 2015). NHS approval was also obtained with each hospital trust. The findings of the study will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER:Clinical Trials registry (NCT02637102) and the ISRCTN registry (ISRCTN55032357).

Project description:BackgroundSevere autoimmune haemolytic anaemia (AIHA) in systemic lupus erythematosus (SLE) patients could be life-threatening and formidable, especially in those nonresponsive to glucocorticoids (GCs) and immunosuppressants (ISAs). Whole-blood exchange transfusion (WBE), with plasma exchange and pathogenic cell removal as well as healthy red blood cell transfusion, could be beneficial. The objective of this study was to investigate the efficacy and safety of WBE in combination with GCs/ISAs.MethodsIn this retrospective study, the clinical data of 22 refractory severe SLE-AIHA inpatients between February 2016 and February 2021 were collected and analysed, among whom 14 patients had received WBE and were compared with those treated with typical second-line therapy of intravenous immunoglobulin and/or rituximab (IVIG/RTX).ResultsAmong the 22 severe refractory SLE-AIHA patients, eight patients received IVIG and/or RTX without WBE (group 1, IVIG/RTX, n = 8), seven patients were given WBE without IVIG/RTX (group 2, WBE alone, n = 7), and seven patients who failed initial IVIG/RTX therapy were given sequential WBE therapy (group 3 IVIG/RTX→WBE, n = 7). Fourteen patients had accepted WBE treatment regardless of prior IVIG/RTX usage (group 2 + 3, WBE ± IVIG/RTX, n = 14). On days 1, 3, 5, and 7 after corresponding therapies, patients of groups 2, 3, and 2 + 3 showed significantly higher levels of haemoglobin (Hb) than patients of group 1. Compared with patients of group 1, patients of groups 2, 3, and 2 + 3 took less time to reach and maintain Hb ≥60 g/L from baseline. Groups 2 and 2 + 3 consumed a lower dose of GCs than group 1 to reach and maintain Hb ≥60 g/L from baseline. Group 1 experienced longer hospital stays than group 2, and group 3's cost of hospitalisation is more than groups 1 and 2. Hbmin <40 g/L may be a key indicative factor for initiating WBE remedy therapy as IVIG/RTX may not be effective enough in 48-72 h in those patients with refractory severe SLE-AIHA. No severe adverse effects were observed in the WBE group.ConclusionsWBE could be a safe and beneficial alternative therapy for refractory severe SLE-AIHA.
