Dabigatran, a new oral anticoagulant for the prevention of stroke in patients with non-valvular atrial fibrillation (AF), exemplifies this issue. Whilst new effective treatments are needed, there are issues in the elderly with dabigatran due to variable drug concentrations, no known antidote and dependence on renal elimination. Published studies showed dabigatran to be cost-effective but there are budget concerns given the prevalence of AF. These concerns resulted in extensive activities pre- to post-launch to manage its introduction.</p><p><bold>Objective</bold>: To (i) review authority activities across countries, (ii) use the findings to develop new models to better manage the entry of new drugs, and (iii) review the implications based on post-launch activities.</p><p><bold>Methodology</bold>: (i) Descriptive review and appraisal of activities regarding dabigatran, (ii) development of guidance for key stakeholder groups through an iterative process, (iii) refining guidance following post launch studies.</p><p><bold>Results</bold>: Plethora of activities to manage dabigatran including extensive pre-launch activities, risk sharing arrangements, prescribing restrictions and monitoring of prescribing post launch. Reimbursement has been denied in some countries due to concerns with its budget impact and/or excessive bleeding. Development of a new model and future guidance is proposed to better manage the entry of new drugs, centering on three pillars of pre-, peri-, and post-launch activities. Post-launch activities include increasing use of patient registries to monitor the safety and effectiveness of new drugs in clinical practice.</p><p><bold>Conclusion</bold>: Models for introducing new drugs are essential to optimize their prescribing especially where concerns. Without such models, new drugs may be withdrawn prematurely and/or struggle for funding.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct><analytic><author><name sortKey="Adamski, J" uniqKey="Adamski J">J.

Dabigatran, a new oral anticoagulant for the prevention of stroke in patients with non-valvular atrial fibrillation (AF), exemplifies this issue. Whilst new effective treatments are needed, there are issues in the elderly with dabigatran due to variable drug concentrations, no known antidote and dependence on renal elimination. Published studies showed dabigatran to be cost-effective but there are budget concerns given the prevalence of AF. These concerns resulted in extensive activities pre- to post-launch to manage its introduction.</p><p><bold>Objective</bold>: To (i) review authority activities across countries, (ii) use the findings to develop new models to better manage the entry of new drugs, and (iii) review the implications based on post-launch activities.</p><p><bold>Methodology</bold>: (i) Descriptive review and appraisal of activities regarding dabigatran, (ii) development of guidance for key stakeholder groups through an iterative process, (iii) refining guidance following post launch studies.</p><p><bold>Results</bold>: Plethora of activities to manage dabigatran including extensive pre-launch activities, risk sharing arrangements, prescribing restrictions and monitoring of prescribing post launch. Reimbursement has been denied in some countries due to concerns with its budget impact and/or excessive bleeding.

This rate will continue unless addressed driven by well-known factors including changing demographics and the continual launch of new premium priced products (Garattini et al., <xref rid="B9" ref-type="bibr">2008</xref>; Godman et al., <xref rid="B10" ref-type="bibr">2013</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). Continued pressure on resources is already resulting in some countries unable to fund new premium priced drugs (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). The number of countries is likely to increase if not addressed with new drugs, including new biological drugs, being launched at US$100,000–400,000 per patient per year or more (Kaiser, <xref rid="B14" ref-type="bibr">2012</xref>; Godman et al., <xref rid="B10" ref-type="bibr">2013</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). This is in no one's best interest especially if new medicines help improve patients' health either because they are more effective, have less side-effects, are easier to administer than current standards or a combination of these factors (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>; Spatz and McGee, <xref rid="B25" ref-type="bibr">2013</xref>).</p><p><bold>Premium prices for new medicines are a concern</bold> among health authorities struggling to maintain, and potentially incompatible with, the European ideals of comprehensive and equitable healthcare (Garattini et al., <xref rid="B9" ref-type="bibr">2008</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). This can lead to conflicts between authorities and pharmaceutical companies with the latter keen to re-coup the considerable monies spent on Research and Development through encouraging the rapid reimbursement and uptake of new medicines. Uptake can be enhanced by companies spending up to one third of their income on marketing activities alongside lobbying activities (Civaner, <xref rid="B2" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>).</p><boxed-text position="float"><label>KEY CONCEPT 1</label><caption><title>Concerns with new medicines</title></caption><p>Pharmaceutical expenditure is under increasing scrutiny among health authorities given ongoing pressures. Premium prices for new medicines are a concern especially if there are safety concerns with new medicines in clinical practice, which applied to new oral anticoagulants.</p></boxed-text><p>These conflicts between companies and authorities can be greater when there are safety concerns with new drugs, and they are subsequently prescribed in a wider population than studied in randomized clinical trials. Typically Phase III clinical trials are conducted under ideal and highly controlled conditions to seek high internal validity to maximize the chance of demonstrating clinical benefit (Fritz and Cleland, <xref rid="B8" ref-type="bibr">2003</xref>). However, this may lead to substantial differences from their subsequent use in clinical practice. Typically Phase III clinical trials do not include treatment preferences and/or multimodal treatment programs (Wells, <xref rid="B29" ref-type="bibr">1999</xref>; Fritz and Cleland, <xref rid="B8" ref-type="bibr">2003</xref>). Phase III clinical trials may also include a placebo group as a comparator in order to isolate the effects of a particular intervention (Fritz and Cleland, <xref rid="B8" ref-type="bibr">2003</xref>). These situations can lead to concerns with the generalizability of the findings when new drugs are being considered as an alternative to current treatments, especially once prescribed in patients with greater co-morbidities than those enrolled into Phase III clinical trials. They have also led to product withdrawals, which is in no one's best interest. Examples include zimelidine, rofecoxib, and natalizumab (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>).</p><p>New oral anticoagulants (NOACs) illustrate some of these tensions as they show promise in the prevention of stroke in patients with atrial fibrillation (AF), offering an alternative to warfarin without the need for INR (International Normalized Ratio) monitoring (Pink et al., <xref rid="B20" ref-type="bibr">2011</xref>; Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). However, there are safety concerns especially in the elderly in addition to potential compliance problems (Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>; Marshall et al., <xref rid="B18" ref-type="bibr">2013</xref>; Xu et al., <xref rid="B30a" ref-type="bibr">2013</xref>).</p><p>AF is the most common clinically significant cardiac arrythmia with an estimated prevalence of 1–2% of the population (Marshall et al., <xref rid="B18" ref-type="bibr">2013</xref>). Current estimates suggest there are 4.5 million people in Europe with AF and 3.03 million in the US (Marshall et al., <xref rid="B18" ref-type="bibr">2013</xref>), with the prevalence of AF likely to double in the next 50 years with ageing populations (Pink et al., <xref rid="B20" ref-type="bibr">2011</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>; Marshall et al., <xref rid="B18" ref-type="bibr">2013</xref>). New drugs are needed since patients with AF have a 5-fold increased risk of cardioembolic stroke compared with those in sinus rhythm (Pink et al., <xref rid="B20" ref-type="bibr">2011</xref>), with a cardioembolic stroke resulting in approximately 20% of patients dying in the acute phase and 60% developing severe disability (Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>). In addition, those patients with AF who survive are left more disabled by their stroke and are more likely to have a recurrence than those with other causes of stroke (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>).</p><p>Anticoagulant therapy with Vitamin K antagonists (VKAs) can reduce by at least 60% the risk of stroke (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). However, there are concerns with warfarin due to the potential of bleeding, the need to tailor doses to the individual with too high a dose potentially causing serious complications and too low a dose losing protection, and the difficulties with maintaining some patients within International Normalized Ratios (Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>).</p><p>Dabigatran received EU marketing authorization in August 2011 (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>) for the prevention of stroke and systemic embolism/clot formation in adult patients with non-valvular AF with one or more of the following risk factors:</p><list list-type="bullet"><list-item><p>Previous stroke, transient ischemic attack or systemic embolism/clot formation.</p></list-item><list-item><p>Left ventricular ejection fraction < 40%.</p></list-item><list-item><p>Symptomatic heart failure > New York Heart Association (NYHA) class 2.</p></list-item><list-item><p>Age > 75 years.</p></list-item><list-item><p>Age > 65 years in combination with additional vascular risk, i.e., patients with diabetes mellitus, coronary artery disease or arterial hypertension.</p></list-item></list><p>Published studies showed a 9% reduction in the prevention of stroke or systemic embolism with dabigatran 110 mg twice daily and 34% for the 150 mg twice daily (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>; Marshall et al., <xref rid="B18" ref-type="bibr">2013</xref>). Overall mortality was also reduced by 12% for the highest dose of dabigatran, which reached statistical significance (Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). There was also an appreciable and consistent reduction in the risk of haemorrhagic stroke ranging from 69 to 74% depending on the dose of dabigatran. The 150 mg twice daily dose of dabigatran also resulted in a statistical significant reduction in ischemic stroke (24% risk reduction) (Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). Dabigatran could also potentially require no monitoring compared with warfarin (Godman et al., <xref rid="B11" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). As a result, dabigatran has the potential to be an important new treatment, especially where regular monitoring with warfarin is problematic or where there are adverse events or other patient issues with warfarin.</p><p>These improvements, coupled with potential savings with dabigatran with the opportunity to reduce patient monitoring, resulted in incremental cost-effectiveness ratios (ICERs) of GB£4831 (€5560)/Quality adjusted life year (QALY) in patients under 80 vs. warfarin and GB£7090 (€8150) above 80 (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). A similar study in Sweden estimated the cost/QALY gained for dabigatran versus warfarin at €7742, increasing to €12,449 in patients who were well controlled with warfarin (Davidson et al., <xref rid="B3" ref-type="bibr">2013</xref>). Other authors have published higher ICERs, e.g., the National Institute for Health and Care Excellence (NICE) increased the base case ICER for dabigatran 150 mg twice to GB£24,173–29,131 (€27,790–33,490)/QALY with different assumptions (NICE, <xref rid="B19" ref-type="bibr">2012</xref>). However, NICE subsequently recommended dabigatran as an alternative to warfarin in patients who meet the criteria outlined in the marketing authorization approval (NICE, <xref rid="B19" ref-type="bibr">2012</xref>).</p><p>However, there have been concerns with the rapid introduction of <bold>dabigatran</bold>. There were an appreciable number of serious adverse events within the first 12 weeks of dabigatran's availability in the US (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). These were principally serious bleeding events or blood clots in the elderly (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). Dabigatran was also the most frequently identified medication involving direct safety-related reports to the FDA in 2011. These include haemorrhage, which was the most frequently reported side-effect (Carley et al., <xref rid="B2a" ref-type="bibr">2014</xref>). These concerns arose due to dabigatran's low mean oral bioavailability, considerable variation in plasma drug concentrations, and dependence on renal elimination of the active metabolite (Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). Consequently, any accumulation of dabigatran in patients with reduced renal function will increase their risk of excessive bleeding, complicated by no effective reversal agent and no commercially available assay to measure blood levels of dabigatran (Legrand et al., <xref rid="B15" ref-type="bibr">2011</xref>; Harper et al., <xref rid="B12" ref-type="bibr">2012</xref>; Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>; Xu et al., <xref rid="B30a" ref-type="bibr">2013</xref>; Reilly et al., <xref rid="B21" ref-type="bibr">2014</xref>). These concerns are enhanced by potentially more elderly patients in clinical practice than seen in the Phase III clinical studies with the belief this would increase the risk of bleeding, which has now been demonstrated (Joppi et al., <xref rid="B13" ref-type="bibr">2013</xref>; Reilly et al., <xref rid="B21" ref-type="bibr">2014</xref>). There were also concerns with dabigantran's budget impact (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). A number of health authorities and health insurance companies across Europe and other countries recognized these issues and initiated extensive pre- and peri-launch programmes to educate physicians and the public regarding the optimal use of dabigatran, especially in elderly patients with poor renal function (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>).</p><boxed-text position="float"><label>KEY CONCEPT 2</label><caption><title>Dabigatran</title></caption><p>The potential for inappropriate prescribing of dabigatran was a concern among health authorities across countries given the considerable variation in plasma concentration levels among the target elderly population, dependency on renal elimination of the active metabolite, no commercially available assay at launch and no effective reversal agent at launch. Consequently, the potential for serious bleeding and deaths if not administered appropriately, which happened in practice.</p></boxed-text><p>Consequently, we undertook a review of health authority and health insurance company activities across Europe pre- to post-launch of dabigatran for the prevention of stroke as an exemplar for developing future models to better manage the entry of new premium priced drugs. We subsequently used this knowledge to suggest future activities that all key stakeholder groups could undertake to optimize their use and reduce the likelihood of new drugs being removed from the market place due to safety concerns in a wider patient population. In addition, suggest activities to help control expenditure on new drugs where there are concerns with their budget impact. We have added to this advice based on post-launch studies with dabigatran in a number of countries.</p></sec><sec sec-type="methods"><title>Methodology</title><p>Principally a descriptive review of initial national, regional or local health authority, health insurance company or physician association activities across Europe regarding dabigatran (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>).</p><p>Demand-side initiatives were collated under four different activities named the 4 Es—Education, Engineering, Economics and Enforcement (Wettermark et al., <xref rid="B30" ref-type="bibr">2009</xref>).

Approximately 20% of the entire cohort was treated with amiodarone, a drug potentially interfering with NOACs, and 3.6% from a subgroup analysis had renal failure, which is an exclusion criterion in trials on NOACs (Joppi et al., <xref rid="B13" ref-type="bibr">2013</xref>).</p><p>The results of this survey demonstrate once more that considerable efforts should be made by pharmaceutical companies and others to include more women and elderly people in randomized clinical trials. Furthermore, while suggesting a role for NOACs in satisfying patients' needs, there is still unmet need. Further phase IV studies are also required to confirm the benefits and clarify the safety profile of novel oral anticoagulants in routine clinical practice (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>).</p></sec><sec><title>New zealand</title><p>A recent study conducted among patients recruited from the medical services at Lower Hutt Hospital and two large general practices in New Zealand also showed less predominance of men than the RE-LY study (42 vs. 63%), an older cohort (73 vs. 71 years) and greater morbidity (Thorne et al., <xref rid="B27" ref-type="bibr">2014</xref>). This is in keeping with differences between patients seen in RCTs compared with those in real life.</p><p>The authors did not observe inappropriate prescribing of dabigatran according to patients' renal function. They believed this may reflect extensive local educational initiatives by the Best Practice Advisory Centre (BPAC) as well as initiatives by local prescribers pre- and peri-launch. This suggests that prescribers can be educated to operate within accepted guidelines, providing guidance for the future (Thorne et al., <xref rid="B27" ref-type="bibr">2014</xref>). There were a high number of adverse events reported to New Zealand Centre for Adverse Drug Reaction Monitoring after the launch of dabigatran. However, increased publicity on adverse events and increasing knowledge about dabigatran among prescribers in New Zealand, especially regarding renal function, led to a reduction in number of adverse reactions reported to the New Zealand Centre for Adverse Drug Reaction Monitoring in recent months (Thorne et al., <xref rid="B27" ref-type="bibr">2014</xref>).</p></sec><sec><title>Ireland</title><p>Patterns of dabigatran prescribing were investigated in a national-level prescription claims database. Dispensing records from January-October 2013 inclusive were studied and patients with a dabigatran supply duration of greater than 35 days were assumed to be non-valvular atrial fibrillation patients. 5887 (85%) patients were identified as having received dabigatran, 5012 (83%) of whom received the drug for >35 days. 62% of patients who received dabigatran for >35 days were 75 years or older and 37% were 80 years or older. 56% of patients were male. A high proportion of patients were found to be concurrently receiving drugs which may increase the bleeding risk associated with dabigatran use: 36% of patients receiving dabigatran for >35 days were found to have also received at least one “caution” drug (defined as per SmPC) when dispensed dabigatran.</p><p>This analysis followed publications from various authorities in Ireland as there were concerns with the prescribing of dabigatran in clinical practice (National Medicines Information Centre, <xref rid="B18a" ref-type="bibr">2012</xref>; Barry, <xref rid="B1a" ref-type="bibr">2013</xref>; Irish Medicines Board, <xref rid="B12a" ref-type="bibr">2013</xref>).

However, it was not until late 2011 with acceptance of its use by SMC for the prevention of stroke and systemic embolism in adult patients with non-valvular AF (SMC, <xref rid="B24" ref-type="bibr">2011</xref>) that greater use was seen in ambulatory care (Figure <xref ref-type="fig" rid="F2">2</xref>) (Scott and McTaggart, <xref rid="B22" ref-type="bibr">2013</xref>). Analysis of the number of patients dispensed a prescription for dabigatran showed a faster and much greater uptake in rural compared with urban areas (Figure <xref ref-type="fig" rid="F2">2</xref>). The reasons for this are currently being explored, but might reflect differences in access to anticoagulant monitoring services and the perceived advantage of dabigatran in this respect (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>).

However, the weighing of the advantages and disadvantages associated with dabigatran, especially in the elderly with poor renal function, needs to be judged carefully and handled appropriately alongside the additional acquisition costs of dabigatran (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>; Xu et al., <xref rid="B30a" ref-type="bibr">2013</xref>; Carley et al., <xref rid="B2a" ref-type="bibr">2014</xref>). This was especially the case in this situation with no widely available assay pre-launch, exacerbated by concerns from the Company regarding the potential for undermining their message about no monitoring (Reilly et al., <xref rid="B21" ref-type="bibr">2014</xref>; Thomas, <xref rid="B26" ref-type="bibr">2014</xref>). These challenges resulted in an extensive range of activities among health authorities, health insurance companies and physician associations across Europe pre- to post-launch to enhance its appropriate use based on factors including age and kidney function (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). Similar findings were seen in New Zealand, Ontario, Canada and Wisconsin, USA (Xu et al., <xref rid="B30a" ref-type="bibr">2013</xref>; Carley et al., <xref rid="B2a" ref-type="bibr">2014</xref>).</p><p>Cases of major bleeding and deaths that were seen with dabigatran soon after its launch, justify the need for the suggested model (Figure <xref ref-type="fig" rid="F1">1</xref>) to improve the managed entry of new drugs (Legrand et al., <xref rid="B15" ref-type="bibr">2011</xref>; Harper et al., <xref rid="B12" ref-type="bibr">2012</xref>; Mannuci et al., <xref rid="B17" ref-type="bibr">2012</xref>; Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). The EMA also reported on 6 November 2011 that there had already been 256 spontaneous reports of serious bleeding resulting in deaths in the EudraVigilance database (EMA, <xref rid="B4" ref-type="bibr">2011</xref>).</p><p>Extensive activities among the authorities included educational activities pre-launch in Stockholm County Council, Sweden, as well as post-launch activities among regions and localities in Germany, Spain, Sweden, and the UK (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). There were also prescribing restrictions in some countries alongside the development of shared care protocols between sectors. It is suggested these activities helped reduce subsequent bleeding among patients in practice, especially among those with poor renal function and, as a result, help preserve the availability of dabigatran. However, it is difficult to substantiate this without definite research. Having said this, some of the findings post launch suggests that such activities helped enhance the appropriate use of dabigatran (Carley et al., <xref rid="B2a" ref-type="bibr">2014</xref>; Thorne et al., <xref rid="B27" ref-type="bibr">2014</xref>). Further efforts are still needed in some countries to improve the prescribing of dabigatran, e.g., Spain (Catalonia) (Troncoso and Diogène, <xref rid="B28" ref-type="bibr">2014</xref>).</p><p>There have also been issues with the additional costs of dabigatran vs. warfarin at GB£919.80 (€1060) per patient per year (UK) given the growing prevalence of AF with currently over 4.5 to 6 million patients across Europe and rising (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). However, there is less of a budget differential in Sweden (Davidson et al., <xref rid="B3" ref-type="bibr">2013</xref>). These combined issues led to (i) prescribing restrictions in some countries alongside prior authorization schemes, e.g., Austria, Belgium, Finland, Slovakia, and Slovenia, (ii) delays with reimbursement in others including Croatia (recently reimbursed as second line to warfarin with a 50% co-payment), the Netherlands, Norway and Portugal (150 mg); and (iii) price: volume and other agreements (risk sharing) to lower the cost of dabigatran, e.g., Ireland, the Netherlands and Slovenia [2]. These concerns also resulted in dabigatran not being reimbursed in some countries, e.g., Estonia, Lithuania, Poland, the Republic of Serbia and the Republic of Srpska (constitutive entity in Bosnia and Herzegovina). Prescribing restrictions and risk sharing arrangements are no doubt preferred by manufacturers versus not having their drugs reimbursed.</p><p>The weighing of the benefits and concerns with dabigatran make it increasingly important for European countries and regions to develop and refine models to further improve the managed entry of new premium priced drugs, even if they do not have a tradition of Health Technology Assessment (HTA). As mentioned, the alternative could be reduced resources to fund new drugs in the future, especially with a growing elderly population, which is already happening (Malmström et al., <xref rid="B16" ref-type="bibr">2013</xref>). Such models may also reduce the possibility of new drugs such as dabigatran being withdrawn from the market due to a greater level of side-effects in a wider co-morbid population. None of these alternative scenarios are in the best interests of any key stakeholder group.</p><p>We hope we have demonstrated why it is imperative that health authorities and health insurance agencies continue to develop and refine new models to better manage the entry of new drugs. We hope we have also provided direction to all key stakeholder groups to further stimulate the debate about potential activities in this critically important area. This especially as the constant introduction of new premium priced drugs is seen as the greatest challenge to the continued provision of equitable and comprehensive healthcare in Europe (Garattini et al., <xref rid="B9" ref-type="bibr">2008</xref>).</p></sec><sec sec-type="conclusion" id="s3"><title>Conclusion</title><p>There were multiple activities pre- to post-launch among authorities across Europe and other countries to improve the prescribing of dabigatran, especially in elderly patients where there are concerns with their renal function. In addition, address potential concerns with the budget impact of dabigatran through for instance price: volume agreements and prescribing restrictions.</p><p>We believe and recommend, based on the experiences with dabigatran and other new premium priced drugs, that it is essential that health authorities develop new models to better manage the entry of new drugs in the future (Figure <xref ref-type="fig" rid="F1">1</xref>). This is becoming critical given the considerable number of new biological drugs in development (Evaluate Pharma, <xref rid="B5" ref-type="bibr">2012</xref>).</p><p>Critical activities for health authorities pre-launch include horizon scanning and budget planning activities. This includes identifying products likely to lose their patent within the next one to two years. This is because the price of generics can be as low as 2–10% of pre-patent loss prices, with activities to enhance the prescribing of low cost generics realizing considerable savings (Godman et al., <xref rid="B10" ref-type="bibr">2013</xref>).</p><p>Educational materials and clinical guidance also need to be developed pre-launch with the help of physicians and patient groups. Key peri-launch activities include developing prescribing indicators for new treatments as well as the critical appraisal of any proposed risk sharing arrangements. Increasingly discounts are preferred for new drugs rather than complicated arrangements including outcome schemes in view of the complexities involved (Adamski et al., <xref rid="B1" ref-type="bibr">2010</xref>; Ferrario and Kanavos, <xref rid="B6" ref-type="bibr">2013</xref>). Essential post launch activities include monitoring of prescribing against agreed guidance with further educational input if needed. Activities also include increasingly entering patients into registries to monitor the effectiveness and safety of new drugs in wider patient populations.</p><p>Without such models, authorities may well struggle to maintain the European ideals of equitable and comprehensive healthcare as well as ensuring funding for new “valued” treatments in target populations. Consequently, the development of new models to better manage the entry of new drugs should be in the interest of all key stakeholder groups.</p></sec><sec><title>Author contributions</title><p>Brian Godman, Rickard E.
