Orphanet J Rare Dis 2024; 19:181. [PMID: 38689282 PMCID: PMC11062018 DOI: 10.1186/s13023-024-03131-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Accepted: 03/03/2024] [Indexed: 05/02/2024] Open
Abstract
BACKGROUND Fabry disease (FD) is a rare lysosomal storage disease associated with glycolipid accumulation that impacts multiple physiological systems. We conducted a systematic literature review (SLR) to characterize the humanistic (quality of life [QoL]) and economic burden of FD. METHODS Searches were conducted in the Embase, MEDLINE®, and MEDLINE® In-Process databases from inception to January 19, 2022. Conference abstracts of specified congresses were manually searched. Additional searches were performed in the Cochrane and ProQuest databases for the humanistic SLR and the National Health Service Economic Evaluations Database for the economic SLR. Studies of patients with FD of any sex, race, and age, and published in the English language were included. There was no restriction on intervention or comparator. For the humanistic SLR, studies that reported utility data, database/registry-based studies, questionnaires/surveys, and cohort studies were included. For the economic SLR, studies reporting economic evaluations or assessing the cost of illness and resource use were included. RESULTS Of the 1363 records identified in the humanistic search, 36 studies were included. The most commonly used QoL assessments were the 36-item Short-Form Health Survey (n = 16), EQ-5D questionnaire descriptive system or visual analog scale (n = 9), and the Brief Pain Inventory (n = 8). Reduced QoL was reported in patients with FD compared with healthy populations across multiple domains, including pain, physical functioning, and depressive symptoms. Multiple variables-including sex, age, disease severity, and treatment status-impacted QoL. Of the 711 records identified in the economic burden search, 18 studies were included. FD was associated with high cost and healthcare resource use. Contributors to the cost burden included enzyme replacement therapy, healthcare, and social care. In the seven studies that reported health utility values, lower utility scores were generally associated with more complications (including cardiac, renal, and cerebrovascular morbidities) and with classical disease in males. CONCLUSION FD remains associated with a high cost and healthcare resource use burden, and reduced QoL compared with healthy populations. Integrating information from QoL and economic assessments may help to identify interventions that are likely to be of most value to patients with FD.

Home-Based Infusion of Alglucosidase Alfa Can Safely be Implemented in Adults with Late-Onset Pompe Disease: Lessons Learned from 18,380 Infusions. BioDrugs 2023; 37:685-698. [PMID: 37326923 PMCID: PMC10432339 DOI: 10.1007/s40259-023-00609-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/21/2023] [Indexed: 06/17/2023]
Abstract
BACKGROUND Enzyme replacement therapy (ERT) with alglucosidase alfa is the treatment for patients with Pompe disease, a hereditary metabolic myopathy. Home-based ERT is unavailable in many countries because of the boxed warning alglucosidase alfa received due to the risk of infusion-associated reactions (IARs). Since 2008, home infusions have been provided in The Netherlands. OBJECTIVES This study aimed to provide an overview of our experience with home-based infusions with alglucosidase alfa in adult Pompe patients, focusing on safety, including management of IARs. METHOD We analysed infusion data and IARs from adult patients starting ERT between 1999 and 2018. ERT was initially given in the hospital during the first year. Patients were eligible for home treatment if they were without IARs for multiple consecutive infusions and if a trained home nurse, with on-call back-up by a doctor, was available. The healthcare providers graded IARs. RESULTS We analysed data on 18,380 infusions with alglucosidase alfa in 121 adult patients; 4961 infusions (27.0%) were given in hospital and 13,419 (73.0%) were given at home. IARs occurred in 144 (2.9%) hospital infusions and 113 (0.8%) home infusions; 115 (79.9% of 144) IARs in hospital and 104 (92.0% of 113) IARs at home were mild, 25 IARs (17.4%) in hospital and 8 IARs (7.1%) at home were moderate, and very few severe IARs occurred (4 IARs in hospital [2.8%] and 1 IAR at home [0.9%]). Only one IAR in the home situation required immediate clinical evaluation in the hospital. CONCLUSION Given the small numbers of IARs that occurred with the home infusions, of which only one was severe, we conclude that alglucosidase alfa can be administered safely in the home situation, provided the appropriate infrastructure is present.

Considerations for Home-Based Treatment of Fabry Disease in Poland during the COVID-19 Pandemic and Beyond. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18168242. [PMID: 34443990 PMCID: PMC8394954 DOI: 10.3390/ijerph18168242] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 07/30/2021] [Accepted: 08/02/2021] [Indexed: 01/30/2023]
Abstract
Current therapy for Anderson–Fabry disease in Poland includes hospital or clinic-based intravenous enzyme replacement therapy with recombinant agalsidase alpha or beta, or oral pharmacological chaperone therapy with migalastat. Some countries around the world offer such treatment to patients in the comfort of their own homes. The 2020–2021 COVID-19 pandemic has pushed global healthcare providers to evolve their services so as to minimize the risk of COVID-19 exposure to both patients and providers; this has led to advances in telemedicine services and the increasing availability of at-home treatment for various procedures including parenteral drug administration. A total of 80% of surveyed Anderson–Fabry disease patients in Poland would prefer home-based treatment, which would be a safe and convenient alternative to clinic-based treatment if patient selection is based on our proposed algorithm. Our recommendations for home-based treatments appear feasible for the long term care of Anderson–Fabry disease patients during the COVID-19 pandemic and beyond. This may also serve as a basis for home-based treatment programs in other rare and ultra-rare genetic diseases.

Abstract
This evaluation determines whether published studies to date meet the key characteristics identified for budget impact analyses (BIA) for medicines, accomplished through a systematic review and assessment against identified key characteristics. Studies from 2001-2015 on 'budget impact analysis' with 'drug' interventions were assessed, selected based on their titles/abstracts and full texts, and their characteristics checked according to key criteria. Out of 1,984 studies, 92 were subsequently identified for review. Of these, 95% were published in Europe and the USA. 2012 saw the largest number of publications (16%) with a decline thereafter. 48% met up to 7 out of the 9 key characteristics. Only 22% stated no conflict of interest. The results indicate low adherence to the key characteristics that should be considered for BIAs and strong conflict of interest. This is an issue since BIAs can be of fundamental importance in managing the entry of new medicines including reimbursement decisions.

Abstract
BACKGROUND Budget impact analysis (BIA) is a relatively recent technique that is supposed to be complementary to more established economic evaluations (EEs). OBJECTIVE We reviewed the BIAs published on drugs in the EU since December 2008, to assess whether these studies have improved in quality in the last few years. METHODS We conducted a literature search on the international databases PubMed and EMBASE. The selected articles were screened using a two-step approach to assess (1) their main methodological characteristics and (2) the level of adherence to the latest BIA definition. The assessment was made by two independent reviewers and any disagreement was resolved through discussion. RESULTS Eventually, 17 articles were reviewed. Thirteen referred to a stand-alone BIA not accompanying a full EE, only nine focussed on a new treatment, 15 were sponsored by the manufacturer of the drug of reference, all but one claiming savings for healthcare budgets. The quality of methods was poor in many of the studies, and only a few of them attempted to estimate real local costs in a credible way. Therefore, the crucial items that in theory make a BIA different from other types of EEs were often the major points of weakness of the studies reviewed. CONCLUSIONS Our review confirmed that the BIA is not yet a well-established technique in the literature and many published studies still fail to reach an acceptable quality. In particular, BIAs funded by pharmaceutical companies appear to be tailored to show short-term savings induced by new, highly priced products.

Abstract
BACKGROUND Enzyme replacement therapy for Fabry disease, consisting of biweekly infusions, interferes daily life. Home treatment proved beneficial. We evaluated a previously reported home treatment algorithm aiming to shorten the period of in-hospital infusions, while ascertaining patient safety. METHODS Retrospective analysis on clinical records of treated Fabry patients. Potentially predictive factors for infusion associated reactions (IARs) were studied: agalsidase antibodies, agalsidase product and dose, FOS-SSI scores, and GLA activity and mutation. A questionnaire evaluated patient satisfaction and compliance. RESULTS Seventy-nine patients were included (41 males, 46% agalsidase antibody positive (AB+)). 85% received home treatment. Home treatment complications were erroneous fast infusion rates (n=4) causing IARs and, rarely, venous access problems. The single SAE was unrelated to home treatment. IgG antibody status was significantly associated with IARs (89% vs. 26% p-value<0.01). Negative antibody status did not preclude IARs. Except for three AB+ patients, all first IARs occurred within 13 infusions. IARs occurred more frequently in patients using agalsidase beta 1.0 mg/kg/eow than agalsidase alpha or beta 0.2 mg/kg/eow, but the time to first IAR did not differ between groups. Four AB+ males experienced IARs after a dose increase. Compliance between home and in-hospital treatment was similar. Most patients preferred home treatment. CONCLUSION In this study home therapy for Fabry disease was safe and improved patient satisfaction. We propose a revised algorithm which allows safe home-treatment in all male patients after 13 instead of 26 infusions, irrespective of ERT preparation or dose. Furthermore, AB+ patients with dosage increase may experience new or increased IARs, necessitating in-hospital observations.

Abstract
AIMS This study estimated the resource implications and budget impact of managing adults with Fabry disease in Italy, from the perspective of the Servizio Sanitario Nazionale (SSN). METHODS A decision model was constructed using published clinical outcomes and clinician-derived resource utilisation estimates depicting the management of adults with Fabry disease in Italy. RESULTS The expected annual cost of managing 220 existing and 20 new Fabry patients in Italy was estimated to be €28·3 million. In an average year, patients receiving enzyme replacement therapy (ERT) with 0·2 mg kg(-1) agalsidase alfa (Replagal; Shire Human Genetic Therapies, Basingstoke, Hampshire, UK) or 1·0 mg kg(-1) agalsidase beta (Fabrazyme; Genzyme Europe BV, Naarden, The Netherlands) are collectively expected to make 4500 hospital attendances to a day ward for infusions, which equates to 2000 eight-h days on the day ward associated with ERT. If all ERT-treated patients received their infusions at home, there would be a marginal reduction in the annual health care cost to manage these patients, and the total annual number of days on the day ward associated with ERT in the second year could potentially be reduced from a mean 2000 to zero, thereby releasing substantial hospital resources for use by non-Fabry patients. Currently, only agalsidase alfa is licensed for home treatment in Italy; hence, only patients receiving this enzyme could be offered home treatment. CONCLUSION Use of agalsidase alfa (0·2 mg kg(-1) ) instead of agalsidase beta (1·0 mg kg(-1)) has the potential to reduce health care costs and release hospital resources in different specialities for alternative use by non-Fabry patients, thereby improving the efficiency of the public health care system in Italy.
