<list list-type="order"><list-item><p>desmopressin acetate (DDAVP), which induces the release of endogenous VWF from endothelial compartments – type 1 patients and a fraction of type 2 patients usually respond</p></list-item><list-item><p>replacement therapy, which involves the transfusion of exogenous VWF contained in plasma-derived FVIII concentrates enriched with VWF (VWF/FVIII concentrates). VWF/FVIII concentrates are the first choice for the treatment of patients with type 3 VWD, for patients with type 2 B (because DDAVP can induce transient thrombocytopenia), and for those patients with type 1 and 2 who are unresponsive to DDAVP or have contraindications to its use.</p></list-item></list></p><p>Therapy with VWF/FVIII concentrates can be administered either on demand, through infusion of the amount of factors determined by the severity of the disease and by the patient’s body weight, in order to stop occasional bleedings, or as prophylaxis in the more severe forms of the disease, through multiple weekly infusions, in order to control recurrent bleeding and to prevent life-threatening hemorrhages.<xref rid="b5-ceor-7-017" ref-type="bibr">5</xref> Patients with severe forms of VWD may have frequent bleeding episodes, especially in those cases with FVIII levels below 20 IU/dL, occurring in type 3 VWD and in some cases with severe forms of type 1 and 2. In these cases large doses of VWF/FVIII concentrates are required to control the bleeding. Prophylaxis with VWF/FVIII concentrates is considered a potential approach for those patients with severe bleeding tendency.<xref rid="b5-ceor-7-017" ref-type="bibr">5</xref>–<xref rid="b8-ceor-7-017" ref-type="bibr">8</xref></p><p>The wide heterogeneity of the bleeding tendency that impacts heavily on quality of life (QoL) contributes to the uncertainties about the potential candidates, the optimal dose of concentrates, and regimes for prophylaxis. Furthermore, patients with VWD have an intact endogenous production of factor VIII (FVIII:C) and long-term exposure to VWF-enriched FVIII concentrates may confer thromboembolic potential to prophylaxis.<xref rid="b9-ceor-7-017" ref-type="bibr">9</xref>–<xref rid="b12-ceor-7-017" ref-type="bibr">12</xref> This observation suggests a particular care in the use of VWF/FVIII concentrates in patients with severe VWD and the need for regular FVIII:C level monitoring in order to maintain an appropriate hemostatic balance.</p><p>In this regard, there is a growing interest in replacement therapy with VWF concentrates almost devoid of FVIII, especially in severe VWD patients, in whom therapies with DDAVP and dual concentrates are not effective, not tolerated, or contraindicated (when a rise in FVIII concentration could predispose the patient to thrombotic events) in order to allow the control of bleeding episodes.</p><p>The objective of the analysis presented here is to assess the cost–benefit ratio of VWF with a low FVIII content (Wilfactin<sup>®</sup>, Laboratoire Francais Du Fractionnement Et Des Biotechnologies, Les Ulis, France) when compared with the VWF/FVIII concentrates treatments (ie, Haemate<sup>®</sup> P, ZLB Behring, Marburg, Germany, and Fanhdi<sup>®</sup>, Instituto Grifols, Barcelona, Spain) currently applied in Italy for long-term prophylaxis in patients with severe VWD, based on data from four case reports. The decision to use single case reports for the pharmacoeconomic analysis depended on two aspects: there are very few patients requiring long-term prophylaxis due to the difficulty in controlling bleeding episodes, and there are even fewer cases in which treatment with VWF with a low FVIII content has been utilized in Italy.</p></sec><sec sec-type="materials|methods"><title>Materials and methods</title><p>A cost–consequence analysis was adopted in order to assess the economic impact of the treatment of VWD from the perspective of the National Health Service (NHS) and society.</p><p>The use of a cost–consequence approach depends on the fact that this analysis measures the health consequences without combining them into one summary effectiveness measure. This kind of analysis describes the value of a health care intervention and has the advantage of being more readily understandable and more likely to be applied by health care decision-makers, leaving the decision regarding the relative importance of different outcomes to the decision-maker.<xref rid="b13-ceor-7-017" ref-type="bibr">13</xref>,<xref rid="b14-ceor-7-017" ref-type="bibr">14</xref></p><p>The analysis described in this paper was conducted on case reports in disaggregated form, as a pooled analysis would not give a robust statistical approach. The analysis has been based on four case reports of type 3 (n=1), type 2M (n=1) and type 1 (n=2) VWD from hemophilia centers at the Molinette Hospital of Turin and University Hospital of Catania on the long-term treatment of VWD with VWF/FVIII concentrates and VWF with a low FVIII content. These centers have clinical experience with patients with severe bleeding tendency receiving long-term prophylaxis (started at least 6 months before) who were switched from VWF/FVIII concentrates to VWF with a low FVIII content because of frequent recurrence of bleeding at the same sites, in order to obtain a better control of bleedings and a better efficacy of the therapy. Patients were included in the analysis if they had severe forms of VWD with periodic bleeding episodes, generally presented a low basal level of FVIII:C and FVIII:ristocetin-cofactor (Ri.CoF) before starting prophylaxis with VWF with a low FVIII content, and had been treated with VWF/FVIII concentrates.</p><p>The analysis includes direct costs associated with drug acquisition, hospital admissions, monitoring visits, and the cost of transfused units of red blood cell concentrates (packed red blood cells), and indirect costs evaluated as the number of working days lost per bleeding episode (loss of productivity).</p><p>In order to collect real-world evidence, a questionnaire addressed to clinicians experienced in the treatment of bleeding disorders was developed.</p><p>In the analysis, outcomes were evaluated in terms of treatment of minor or major bleeding episodes and related costs. The time horizon was 1 year.</p><p>The comparators used in the pharmacoeconomic evaluation were VWF/FVIII concentrates (Haemate<sup>®</sup> P and Fanhdi<sup>®</sup>), as these are the most used VWF/FVIII concentrates in the Italian clinical practice setting for long-term prophylaxis in the treatment of VWD. Both medicinal products, VWF/FVIII concentrates and VWF with a low FVIII content, are authorized in Italy for VWD. The concentrates were administered for prophylaxis at the following dosage: VWF/FVIII concentrates (Fandhi<sup>®</sup>) 40 IU/kg three times per week; VWF/FVIII concentrates (Haemate<sup>®</sup> P) from 35 to 50 IU/kg three times per week; VWF with a low FVIII content from 30 to 50 IU/kg twice per week, and, in one case, 30 IU/kg three times per week. A single bleeding episode was treated with replacement therapy – that is, 30–50 IU/kg/day per 3 days of concentrates, according to National Guidelines and Summary of Product Characteristics.<xref rid="b1-ceor-7-017" ref-type="bibr">1</xref></p><p>The unitary cost of concentrates was obtained from Telematic Pharmaceutical Compendium 2013 <ext-link ext-link-type="uri" xlink:href="http://www.farmadati.it/">http://www.farmadati.it/</ext-link> and is equivalent to the ex-factory price that represents the maximum cost for the NHS structures. The cost of outpatients visits, transfusion of blood components, and laboratory and diagnostic tests are set in the “National Outpatient Tariffs Ministerial Decree [DM] 1997”. The cost per unit of blood concentrate is set in the “DM 5th November 1996 and State-Regions Agreement 24th July 2003”. The absorption of health care resources was calculated considering the Diagnosis Related Group (DRG) version 24 in order to assess DRG refund value for day hospital and for ordinary hospitalization. The cost of hospitalization and day hospital was derived from “National Hospital Tariffs DM 18th October, 2012”.</p><p>Indirect costs were evaluated in terms of loss of productivity. The human capital method was adopted for the determination of the cost due to loss of productivity. Based on this approach, each day of absence from work, results in a simultaneous reduction in production. On the basis of this methodology, a value equivalent to the value generated from work for the same time period should be given to the working days lost due to illness.<xref rid="b15-ceor-7-017" ref-type="bibr">15</xref></p><p>Here, all working days lost (in 1 year) due to disease-related medical and diagnostic investigations, are considered.

Health care cost includes monitoring visits, diagnostic and laboratory tests, transfusion requirements, and hospitalizations (<xref ref-type="table" rid="t1-ceor-7-017">Table 1</xref>).</p><p>Although the cost of long-term prophylaxis was found to be higher with VWF with a low FVIII content, the cost per bleeding episodes per year was considerably reduced (in Case 1) or eliminated (in Cases 2–4) with VWF with a low FVIII content with respect to VWF/FVIII concentrates (<xref ref-type="table" rid="t1-ceor-7-017">Table 1</xref>, column 6: Cost of bleeding episodes per year). Indeed, in these four cases, VWF with a low FVIII content was able to reduce the number of bleeding episodes and consequently to minimize the cost of replacement therapy.</p><p>In all cases, health care costs were found to be substantially lower with VWF with a low FVIII content with respect to VWF/FVIII concentrates (<xref ref-type="table" rid="t1-ceor-7-017">Table 1</xref>, column 17: Health care cost per year without cost of treatment).</p><p>Indirect costs were evaluated in terms of number of working days lost (<xref ref-type="table" rid="t2-ceor-7-017">Table 2</xref>). These data show that replacement therapy with VWF with a low FVIII content was able to reduce the number of working days lost per bleeding episode together with the discomfort related to bleedings and, consequently, to improve the QoL in all these patients.</p><p>In one case report (Case 4), the cost of loss of productivity was not calculated, as the patient was retired. Despite this, the days of well-being lost due to illness may be considered and have an impact on the QoL of this patient.</p><p>The results show data of pharmaceutical costs, health care costs, and indirect costs (loss of productivity) relative to each case (<xref ref-type="table" rid="t3-ceor-7-017">Tables 3</xref>–<xref ref-type="table" rid="t6-ceor-7-017">6</xref> and <xref ref-type="fig" rid="f1-ceor-7-017">Figures 1</xref>–<xref ref-type="fig" rid="f4-ceor-7-017">4</xref>). These results show that the replacement therapy, both with VWF/FVIII concentrates and VWF with a low FVIII content, accounts for most of the total cost.</p><p>Although the dose to achieve full control of bleeding episodes depends on many factors, including in particular patient-related factors, it is possible to observe a minimization of doses of concentrates after the switch to VWF with a low FVIII content (<xref ref-type="table" rid="t1-ceor-7-017">Table 1</xref>, column 3: Concentrates IU/year). In the four cases, long-term prophylaxis with VWF with a low FVIII content allowed the achievement of good control of bleedings, minimizing the cost of hospital admittances and transfusions of blood components. The reduction of these events with prophylaxis with VWF with a low FVIII content was found to afford a reduction in the health care costs per patient per year in all the case reports analyzed (<xref ref-type="table" rid="t7-ceor-7-017">Table 7</xref>, column 2: Total health care costs without pharmaceutical costs avoided with VWF with a low FVIII content per patient/year).</p><p>Long-term prophylaxis with VWF with a low FVIII content, allowed in all cases the use of a lower quantity of this concentrate with respect to the VWF/FVIII concentrates. Nevertheless only in one case report (Case 2) was it possible to observe a reduction in pharmaceutical costs per patient per year (<xref ref-type="table" rid="t7-ceor-7-017">Table 7</xref>, column 3: Pharmaceutical cost avoided with VWF with a low FVIII content per patient/year).</p><p>Furthermore these results show a reduction in indirect costs, evaluated as a reduction of the number of working days lost per bleeding episode, with a related positive impact on QoL (<xref ref-type="table" rid="t7-ceor-7-017">Table 7</xref>, column 4: Indirect cost avoided with VWF with a low FVIII content per patient/year).</p><p>The analysis of these four case reports shows that VWF with a low FVIII content seems be a cost effective treatment option for patients with severe VWD phenotype, in whom therapies with DDAVP and dual concentrates are partially or not effective, non-tolerated or contra-indicated (when a rise of FVIII concentration could predispose the patient to thrombotic events), aimed to obtain a better control of bleeding episodes and consequently to improve the QoL.</p></sec><sec sec-type="discussion"><title>Discussion</title><p>The treatment of a bleeding episode in VWD patients requires correction of the VWF deficiency (the defect in primary hemostasis) and the impaired secondary hemostasis (to increase the potentially low FVIII:C level). Apart from the administration of DDAVP in mild/moderate cases, replacement therapy with concentrates is the therapy of choice for bleeding situations or for short-term prophylaxis during surgery or clinical interventions,<xref rid="b17-ceor-7-017" ref-type="bibr">17</xref>–<xref rid="b19-ceor-7-017" ref-type="bibr">19</xref> while for long-term prophylaxis few retrospective or prospective data are available to date.<xref rid="b20-ceor-7-017" ref-type="bibr">20</xref>–<xref rid="b26-ceor-7-017" ref-type="bibr">26</xref></p><p>The greatest experience with secondary long-term prophylaxis in Italy has been with prophylaxis implemented in a cohort of Italian patients with VWD. In the study of Federici et al,<xref rid="b24-ceor-7-017" ref-type="bibr">24</xref> among 89 patients who needed treatment with VWF/FVIII concentrates during the previous 2 years because of one or more bleeding episodes, eleven were included in a prophylaxis program because of frequent recurrence of bleeding at the same sites. When prophylaxis was compared with previous on-demand regimens, in all the eleven cases, the annual total consumption of concentrates, the number of transfused blood units, and the number of days spent in hospital were found to be significantly reduced. Similar results were obtained in a Swedish study by Berntorp and Petrini.<xref rid="b22-ceor-7-017" ref-type="bibr">22</xref> In that study, 35 patients with mostly type 3 VWD, prophylaxis was associated with a substantial decrease in the annual number of bleeding events.</p><p>As regards VWF with a low FVIII content, as far as we are aware, only one prospective study is available that includes, as additional experience, data on long-term prophylaxis in four patients with type 3 VWD. The study of Borel-Derlon et al<xref rid="b26-ceor-7-017" ref-type="bibr">26</xref> investigated the efficacy and safety of VWF with a low FVIII content to treat patients with clinically severe VWD by merging the results of two comparable protocols conducted prospectively in five European (Italy is included) and twelve French centers. In that study, four patients received secondary long-term prophylaxis (of 17 months’ duration) with VWF with a low FVIII content in order to prevent skin and musculoskeletal bleedings. After the long-term prophylaxis, the number of bleedings was substantially reduced.</p><p>In our analysis, we report on four adult patients (two with type 1 VWD, one with type 2M VWD, and one with type 3 VWD) who switched the long-term prophylaxis from VWF/FVIII concentrates to VWF with a low FVIII content in order to obtain better control of bleeding episodes and better efficacy of the treatment. In all these cases, VWF with a low FVIII content treatment was found to be an effective tolerated modality that was highly beneficial for the patients both in terms of a reduction in bleeding episodes and in terms of cost–benefit ratio.</p><p>To the best of our knowledge, this is the first analysis to have investigated the impact of secondary long-term therapies with VWF with a low FVIII content and the most used VWF/FVIII concentrates (ie, Haemate<sup>®</sup> P and Fanhdi<sup>®</sup>), in the Italian clinical practice setting, on clinical outcome (ie, bleeding frequency, hospitalizations) and indirect/social outcomes (reduction in number of working days lost per bleeding). As no previous studies have addressed this aspect, it is difficult to make any comparison. However long-term prophylaxis with VWF with a low FVIII content was found to be associated with a significant reduction of the number of days spent on patient care (hospitalizations, outpatient visits, laboratory and other diagnostic examinations) together with a decrease in total concentrate consumption for bleedings, in all case reports considered.</p><p>The main limitation of the analysis is that it was based on single case reports, because few patients are in long-term prophylaxis with VWF/FVIII concentrates or VWF with a low FVIII content in the Italian clinical practice setting. Further case reports of long-term prophylaxis treatment with concentrates in VWD are necessary to support the results obtained in this primary analysis.</p><p>Despite the limitations of the use of single case reports for the analysis, it seems that long-term prophylaxis with VWF with a low FVIII content is likely to be a cost-effective approach with a favorable impact on the reduction of health care resource consumption and that also allows the patient to resume their normal life and work activities (the number of working days lost was found to be considerably reduced after switching to VWF with a low FVIII content [<xref ref-type="table" rid="t2-ceor-7-017">Table 2</xref>, column 2]). These data are consistent with the improvement in the QoL of the patients, which is a primary objective of any health care intervention.</p></sec><sec><title>Conclusion</title><p>This analysis shows that VWF with a low FVIII content was more able to control bleeding episodes and, consequently, to reduce the health care interventions necessary, with respect to VWF/FVIII concentrates, in four patients with severe VWD. Although these are preliminary data, they are likely to contribute to establishing the role of specific concentrates for the long-term prophylaxis of severe cases of VWD. Nevertheless, a large collection of clinical data is needed so as to assess regimens, comparative effectiveness, and the cost-effectiveness of long-term prophylaxis treatment in patients with VWD, in order to evaluate which of the available concentrates has a better cost–benefit ratio in patients with severe VWD.</p></sec></body><back><ack><title>Acknowledgments</title><p>The research was supported by an unconditional grant from Laboratoire Francais Du Fractionnement Et Des Biotechnologies.</p></ack><fn-group><fn><p><bold>Author contributions</bold></p><p>All authors made substantial contributions to the conception and design of the research and to the acquisition, analysis, and interpretation of data; drafted the article and revised it critically for important intellectual content; and gave their final approval of the version to be published.</p></fn><fn><p><bold>Disclosure</bold></p><p>The authors declare no conflicts of interest in this work.</p></fn></fn-group><ref-list><title>References</title><ref id="b1-ceor-7-017"><label>1</label><element-citation publication-type="journal"><person-group person-group-type="author"><name><surname>Federici</surname><given-names>AB</given-names></name><name><surname>Castaman</surname><given-names>G</given-names></name><name><surname>Mannucci</surname><given-names>PM</given-names></name></person-group><article-title>Italian Association of Hemophilia Centers (AICE).
