Objective: To assess the economic value of carfilzomib (Kyprolis), this study developed the Kyprolis Global Economic Model (K-GEM), which examined from a United States (US) payer perspective the cost-effectiveness of carfilzomib-lenalidomide-dexamethasone (KRd) versus lenalidomide-dexamethasone (Rd) in relapsed multiple myeloma (RMM; 1–3 prior therapies) based on results from the phase III ASPIRE trial that directly compared these regimens.
Methods: A partitioned survival model that included three health states of progression-free (on or off treatment), post-progression, and death was developed. Using ASPIRE data, the effect of treatment regimens as administered in the trial was assessed for progression-free survival and overall survival (OS). Treatment effects were estimated with parametric regression models adjusting for baseline patient characteristics and applied over a lifetime horizon. US Surveillance, Epidemiology and End Results (1984–2014) registry data were matched to ASPIRE patients to extrapolate OS beyond the trial. Estimated survival was adjusted to account for utilities across health states. The K-GEM considered the total direct costs (pharmacy/medical) of care for patients treated with KRd and Rd.
Results: KRd was estimated to be more effective compared to Rd, providing 1.99 life year and 1.67 quality-adjusted life year (QALY) gains over the modeled horizon. KRd-treated patients incurred $179,393 in total additional costs. The incremental cost-effectiveness ratio (ICER) was $107,520 per QALY.
Limitations: Extrapolated survival functions present the greatest uncertainty in the modeled results. Utilities were derived from a combination of sources and assumed to reflect how US patients value their health state.
Conclusions: The K-GEM showed KRd is cost-effective, with an ICER of $107,520 per QALY gained against Rd for the treatment of patients with RMM (1–3 prior therapies) at a willingness-to-pay threshold of $150,000. Reimbursement of KRd for patients with RMM may represent an efficient allocation of the healthcare budget. 相似文献
Steindl worked all of his life to intergrate the explanation of cycles and trends. In his most elaborate model, stochastic innovations trigger off a dynamic process among innovators and their competitors acting through multiplier distribution of income, accumulation of profit and utilization of capacities. History and institutions find ample room in this model and so stabilization policy becomes a complex process. Demand management appears secondary to income policy, competition policy, technology policy and to stabilization of expectations. Steindl refused to give direct policy advice, but indirectly the Austrian policy of Austrokeynesianism heavily learned from Steindl. 相似文献
For a long time, China's impressive growth performance has been driven by investment and high productivity gains. Based on a discussion of possible overcapacities and overinvestment in China, this paper investigates the sustainability of China's investment and export‐driven growth model. Since the turn of the millennium, buoyant capital inflows and low interest rates have been at the root of overinvestment and misallocation of capital, which necessitated export subsidies to clear markets. The overinvestment boom is argued to have ended around 2014. Since then, the overcapacities have weakened China's bargaining position in the US–Chinese trade conflict and have tempted Chinese authorities to postpone the restructuring of the Chinese economy by providing low‐interest credit. The gradual reemergence of quasi‐soft budget constraints is seen to undermine China's long‐term growth potential. 相似文献
China's fixed its exchange rate at 8.28 yuan to the dollar from1994 to July 2005, and has only allowed for a small appreciationsince then. China's productivity growth has been very high relativeto most other countries: its trade surplus has been rising andit continues to accumulate large dollar exchange reserves. Manyobservers, including high officials in the US government, takethis as per se evidence that the renminbi is undervalued. Tobalance China's international competitiveness and reduce itstrade surplus, they want the renminbi to appreciate much more.This common presumption of renminbi undervaluation is wrong,and its appreciation need not reduce China's trade surplus butwould cause serious deflation in China. To show this, we considerinternational adjustment between China and the US from bothan asset market and a labor market perspective, and comparethis to Japan's unsuccessful appreciation of the yen from 1971to 1995. During a time of economic catch-up and rapid financialtransformation, fixing the exchange rate is the preferred wayof anchoring the domestic price level. (JEL codes: F15, F31,F33) 相似文献
Over the past three decades, we find that asymmetric policy responses heavily contributed to manias and bursting bubbles that eventually trapped the major industrial economies into near zero short‐term interest rates with rapidly rising public indebtedness. The article uses the endogenous business cycle theories of Wicksell, Mises, Schumpeter, Hayek and Minsky to show how ostensible counter‐cyclical monetary policies are asymmetric, as central banks are less willing to raise interest rates in booms than cut them when bubbles collapse. After interest rates have fallen towards zero, fiscal policy is called on which sooner or later becomes bounded by extraordinary debt to GDP ratios. Central banks hesitate to raise interest rates even in the face of a partial economic recovery because the cost of public debt service would become prohibitive. The economies then languish at very low interest rates that encourage low productivity real investments and a continual threat of bubbles in asset and raw material markets. This makes them unable to deal with further macroeconomic shocks. 相似文献
It's hardly news that business leaders work in increasingly uncertain environments, where failures are bound to be more common than successes. Yet if you ask executives how well, on a scale of one to 10, their organizations learn from failure, you'll often get a sheepish "Two-or maybe three" in response. Such organizations are missing a big opportunity: Failure may be inevitable but, if managed well, can be very useful. A certain amount of failure can help you keep your options open, find out what doesn't work, create the conditions to attract resources and attention, make room for new leaders, and develop intuition and skill. The key to reaping these benefits is to foster "intelligent failure" throughout your organization. McGrath describes several principles that can help you put intelligent failure to work. You should decide what success and failure would look like before you start a project. Document your initial assumptions, test and revise them as you go, and convert them into knowledge. Fail fast-the longer something takes, the less you'll learn-and fail cheaply, to contain your downside risk. Limit the number of uncertainties in new projects, and build a culture that tolerates, and sometimes even celebrates, failure. Finally, codify and share what you learn. These principles won't give you a means of avoiding all failures down the road-that's simply not realistic. They will help you use small losses to attain bigger wins over time. 相似文献
Business life has always featured the unpredictable, the surprising, and the unexpected. But in today's hyperconnected world, complexity is the norm. Systems that used to be separate are now intertwined and interdependent, and knowing the starting conditions is no guide to predicting outcomes; too many continuously changing interactive elements are in play. Managers looking to navigate these difficulties need to adopt new approaches. They should drop outmoded forecasting tools-for example, ones that rely on averages, which are often less important than outliers. Instead, they should use models that simulate the behavior of the system. They should also make sure that their data include a good amount of future-oriented information. Risk mitigation is crucial as well. Managers should minimize the need to rely on predictions-for instance, they can give users a say in product design. They can decouple elements in a system and build in redundancy to minimize the consequences of a partial system failure, and turn to outside partners to extend their own company's capabilities. They can complement hard analysis with "soft" methods such as storytelling to make potentially important future possibilities more real. And they can make trade-offs that keep early failures small and provide the diversity of thought needed in a nimble organization faced with complexity on virtually every front. 相似文献
Collecting the most important results of about 80 empirical merger studies, this study condenses the bewildering spectrum of results to 18 stylized facts. Most important, no more than a quarter of the mergers increase consumer welfare; another quarter increase profits at the cost of consumers; half of the mergers reduce the value of the firm. Targets' shareholders win, while bidders' shareholders break even upon the announcement of a merger, but lose significantly in the long run. Seen relatively, horizontal mergers fare best, especially if they are focus-increasing. Cash-financed mergers fare better than stock-financed and strategic mergers fare better than financial ones. Confronting the stylized facts with existing merger theory reveals some major paradoxes; confronting them with existing competition policy reveals the need for a modification and intensification, as mergers increase concentration, and corporate policy strives towards still higher concentration. As a summary ten lessons are extracted on what we may have learnt, and on what is still open. 相似文献
