Objective: To evaluate cost-effectiveness of brentuximab vedotin in patients with relapsed/refractory Hodgkin lymphoma who have received autologous stem cell transplantation, from a Scottish healthcare payer perspective.
Methods: A Microsoft Excel-based partitioned survival model comprising three health states (progression-free survival [PFS], post-progression survival, and death) was developed. Relevant comparators were chemotherapy with or without radiotherapy (C/R) and C/R with intent to allogeneic hematopoietic stem cell transplantation (alloSCT). Data were obtained from the pivotal phase II single-arm trial in 102 patients (SG035-0003; NCT00848926), a systematic literature review and clinical expert opinions (where empirical evidence was unavailable). PFS and overall survival for brentuximab vedotin were estimated using 5-year follow-up data from SG035-0003, and extrapolated using event rates observed for comparator treatments from published survival data. Resource use included drug acquisition and administration; alloSCT; treatment of adverse events; and long-term follow-up. Deterministic and probabilistic sensitivity analyses were conducted to evaluate the impact of uncertainty.
Results: In the base case, the incremental cost-effectiveness ratio (ICER) for brentuximab vedotin was £38,769 per quality-adjusted life year (QALY) vs C/R, whereas C/R with intent to alloSCT was dominated by brentuximab vedotin. ICERs for brentuximab vedotin generated by the deterministic sensitivity analysis ranged between £32,000–£54,000 per QALY. Including productivity benefits reduced the ICER to £28,881 per QALY.
Limitations: Limitations include lack of comparative data from this single arm study and the heterogeneous population. Inconsistent baseline characteristic reporting across studies prevented complete assessment of heterogeneity and the extent of potential bias in clinical and cost-effectiveness estimates.
Conclusions: Although the base case ICER is above the threshold usually applied in Scotland, it is relatively low compared with other orphan drugs, and lower than the ICER generated using a previous data cut of SG035-0003 that informed a positive recommendation from the Scottish Medicines Consortium, under its decision-making framework for assessment of ultra-orphan medicines. 相似文献
This article discusses the issue of cinema screen commercials and suggests that it should be considered within the context of movie theatre intermission time utilization, where the other alternatives are short, commercially sponsored films or illuminated theatres. A two-stage attitudinal survey of movie goers shows that the majority prefer to have something on the screen during intermission time. Respondents expressed negative attitudes towards cinema screen commercials, resulting in short, commercially sponsored films being the most preferred alternative. Negative attitudes do not imply agreement with the banning of commercials, nor a willingness to share its costs. The relative ranking of illuminated theatres over cinema screen commercials changed after respondents were exposed to the economic implications of their choice. 相似文献
The relationship banking literature suggests that business relationships play an important role in the loan decisions of small banks. We test one aspect of this hypothesis using a cross-sectional panel dataset of small banks located in Texas from 1994 to 2002. Our results suggest that small banks located in smaller counties escalate their commitment to bad loans when compared with those located in larger counties, even after controlling for psychological and social factors that influence escalation tendencies. These results highlight the need for small banks to trade-off the positive benefits of adopting a relationship banking strategy against its unintended negative consequence. We provide some suggestions on how small banks may lessen their escalation tendencies despite adopting a relationship banking strategy. The results of this study also suggest that small and medium-sized enterprises (SMEs) that develop strong relational bonds with small banks may benefit from continued access to credit facilities, especially during periods when they experience financial distress. 相似文献
Individualism/Collectivism is the most widely used cultural dimension in the marketing literature; yet researchers suggest that distinctions within cultures, such as the horizontal and vertical dimensions of Individualism and Collectivism (Singelis et al., 1995; Shavitt et al., 2006), may provide better insights into consumption behavior and responses to marketing stimuli. However, the 32-item attitudinal scale typically used to measure H/V dimensions has been plagued by measurement problems limiting its use and applicability in cross-cultural marketing and consumer research. This paper presents data from six samples in four countries (China, Denmark, India, the U.S.) conducted to test a parsimonious and psychometrically stable 14-item scale measuring the horizontal/vertical and individualist/collectivist dimensions of culture. Theoretical and methodological support for the new scale is offered. The 14-item reduced scale adequately taps into the domain of the construct. 相似文献
Existing studies on women directorships present equivocal results on the association between appointing women directors and firm performance. These studies tend to focus on western countries and largely ignore investors' reactions to such appointments. This paper applies the financial event study method and finds that investors generally respond positively to the appointment of women directors in Singaporean firms. Regression analyses also reveal that investors are most receptive when the women are independent directors and are least receptive when the directors assume the CEO role. This study not only tests the theory of gender diversity in an Asian context but also examines whether investors react systematically to the different positions that women directors hold on corporate boards, a question that has received little attention in prior studies. 相似文献
We investigate how new information impacts quote clustering in the bond market. We find that clustering, along with quote activity, price volatility and bid-ask spreads, increases sharply in the minutes following releases of macroeconomic news. Each returns to near-normal levels within the hour. Effects are strongest for more liquid on-the-run notes and for the announcements typically associated with substantial information flow. The strong positive comovement of clustering, quote activity, price volatility, and bid-ask spreads supports the conclusion that innovations of these variables are endogenous to the arrival and incorporation of information into prices. 相似文献
In a conversation held in June 2016 between Nobel laureate Eugene Fama of the University of Chicago and Joel Stern, chairman and CEO of Stern Value Management, Professor Fama revisited some of the landmarks of “modern finance,” a movement that was launched in the early 1960s at Chicago and other leading business schools, and that gave rise to Efficient Markets Theory, the Modigliani‐Miller “irrelevance” propositions, and the Capital Asset Pricing Model. These concepts and models are still taught at prestigious business schools, whose graduates continue to make use of them in corporations and investment firms throughout the world. But while acknowledging the staying power of “modern finance,” Fama also notes that, even after a half‐century of research and refinements, most asset‐pricing models have failed empirically. Estimating something as apparently simple as the cost of capital remains fraught with difficulty. He dismisses betas for individual stocks as “garbage,” and even industry betas are said to be unstable, “too dynamic through time.” What's more, the wide range of estimates for the market risk premium—anywhere from 2% to 10%—casts doubt on their reliability and practical usefulness. And as if to reaffirm the fundamental insight of the M&M “irrelevance” propositions—namely, that what companies do with the right‐hand sides of their balance sheets “doesn't matter”—Fama observes that “we still have no real resolution on the key questions of debt and taxes, or dividends and taxes.” But if he has reservations about much of modern finance, Professor Fama is even more skeptical about subfields now in vogue such as behavioral finance, which he describes as “mostly just dredging for anomalies,” with no underlying theory and no testable predictions. Although he does not dispute that a number of well‐documented traits from cognitive psychology show up in individual behavior, Fama says that behavioral economists have thus far failed to come up with a testable theory that links cognitive psychology to market prices. And he continues to defend the concept of “efficient markets” with which his name has long been closely associated, while noting that empirically based asset pricing models such as his (with Ken French) “three‐factor” CAPM have produced much better results than the standard CAPM. 相似文献
We hypothesize that age similarity among small shareholders acts as an implicit coordinating device for their actions and, thus, could represent an indirect source of corporate governance in firms with dispersed ownership. We test this hypothesis on a sample of Swedish firms during the 1995-2000 period. Consistent with our hypothesis, we find that compared with shareholders of differing ages, same-age noncontrolling shareholders sell more aggressively following negative firm news; firms with more age-similar small shareholders are more profitable and command higher valuation; and an increase (decline) in a firm's small shareholder age similarity brings a significantly large increase (decline) in its stock price. The last effects are more pronounced in the absence of a controlling shareholder. 相似文献
The “folk theorem” in game theory implies that any outcome that is better for all players than some single period Nash outcome can be achieved through noncooperative equilibrium in repeated games with discounting. Whether the folk theorem holds for a repeated Cournot oligopoly as the number of firms, N, increases without bound, is investigated. It is shown that the folk theorem holds in the limit iff demand increases at the same rate as the number of firms and the Cournot price sequence is bounded strictly above by the supremum of marginal cost for large N. 相似文献
