Access with Evidence Development: The US Experience

The concept of access with evidence development (AED), also known as ‘coverage with evidence development’ in the Medicare programme, has long been discussed as a policy option for ensuring more appropriate use of new technologies in the US. This article provides a comprehensive overview of more than 10 years of US experience with AED, both in the public and private healthcare sectors. Beginning with a discussion of the successes of private plans conditional coverage for high-density chemotherapy for autologous bone marrow transplants for metastatic breast cancer and Medicare’s conditional coverage of lung-volume-reduction surgery in the 1990s, the article moves on to describe how Medicare worked to codify AED as one of its coverage policy options in the early part of this decade. More recent private and public sector initiatives are also discussed, including an overview of barriers to implementing AED. Despite the complexity of political, financial and ethical issues faced in implementation, AED is now a permanent fixture of US coverage policy. Future initiatives within the Medicare programme and with private payers in the US are much more likely to succeed by relying upon the simple but consequential principles laid out at a Summit convened in Banff, Alberta, Canada in 2009 and presented in another article in this issue.

Improving the efficiency and effectiveness of pragmatic clinical trials in older adults in the United States

Pragmatic clinical trials (PCTs) seek to improve the generalizability and increase the statistical power of traditional explanatory trials. They are a major tenet of comparative effectiveness research. While a powerful study design, PCTs have been limited by high cost, modest efficiency, and limited ability to fill relevant evidence gaps. Based on an American Reinvestment and Recovery Act (ARRA) supported meeting of national stakeholders, we propose several innovations and future research that could improve the efficiency and effectiveness of such studies focused in the U.S. Innovations discussed include optimizing the use of community based practices through partnership with Practice Based Research Networks (PBRNs), using information technology to simplify PCT subject recruitment, consent and randomization processes, and utilizing linkages to large administrative databases, such as Medicare, as a mechanism to capture outcomes and other important PCT variables with lower subject and research team burden. Testing and adaptation of such innovations to PCT are anticipated to improve the public health value of these increasingly important studies.

Incorporating stakeholder perspectives in developing a translation table framework for comparative effectiveness research.

This project used a stakeholder-driven process to understand the factors that drive the selection of study designs for comparative effectiveness research (CER). The project assembled a diverse stakeholder committee to explore the basis of a translation framework and gathered input through surveys, interviews and an in-person meeting. Stakeholders recommended different study designs for the CER topic areas and identified different outcomes as the most important outcomes to study in each area. During the discussions, stakeholders described a variety of factors that influenced their study design recommendations. The stakeholder activities resulted in the identification of several key themes, including the need to have a highly specific detailed research question before discussing appropriate designs and the need to use multiple studies, potentially of different designs, to address the CER topic areas. The insights and themes from this project may inform efforts to develop a translation table.

Futurescapes: expectations in Europe for relative effectiveness evidence for drugs in 2020

AIM Explore key factors influencing future expectations for the production of evidence of relative effectiveness (RE) for drugs in Europe in 2020; construct three plausible future scenarios for RE evidence generation. MATERIALS & METHODS Semi-structured key informant interviews and three rounds of modified Delphi to gather expert perspectives and develop future scenarios. RESULTS & CONCLUSION Most influential factors were degree of regulator use of postmarketing authorization (postlaunch) efficacy studies and adaptive licensing; degree of pan-European health technology assessment body coordination in reviewing prelaunch evidence and demanding postlaunch studies; the nature of regulator - health technology assessment body interaction. The most likely scenario entailed some change with postlaunch regulatory studies driving the likely nature of RE evidence generated.

Recommendations for the design of Phase 3 pharmaceutical trials that are more informative for patients, clinicians, and payers

BACKGROUND Pharmaceutical pragmatic clinical trials (PCTs) are designed to provide the type of evidence that is desired by patients, clinicians and payers but too often missing from traditional regulatory trials. PURPOSE This paper presents framework for designing pragmatic trials incorporating evidence desired by post-regulatory decision makers while remaining within acceptable standards for regulatory approval. METHODS Following a stakeholder meeting convened in May of 2009 to identify gaps in information collected in Phase 3 trials, CMTP staff and the authors drafted recommendations for Pragmatic Phase 3 Pharmaceutical Trials. This draft was circulated first to technical working group members for their comments. After revising the document based on these comments, it was distributed electronically to other select experts and then made available for public comment. The final version of the EGD appears on the CMTP website. RESULTS The process resulted in a set of 10 recommendations for conducting Phase 3 trials that met regulatory needs while addressing information important to physicians, patients, payers, and policy-makers. These recommendations encompassed three primary areas: generalizability from the trial participants to the clinical population of interest; effectiveness relative to active comparators; and consistently measured relevant outcomes for coverage and treatment decisions. LIMITATIONS While stakeholders were involved throughout the process, not all recommendations will meet the needs of all stakeholders. CONCLUSIONS Pragmatic trial design need not be deferred until a product is in widespread use. Incremental movement toward the more pragmatic design of Phase 3 trials is desirable.

The future of comparative effectiveness and relative efficacy of drugs: an international perspective

Drug development takes place in a global marketplace, albeit with the USA and EU markets currently dominating. In the USA, demands for comparative effectiveness research have gained traction against a backdrop of health delivery reform, while European stakeholders deliberate the role of relative effectiveness in health technology assessment, trying to reduce the duplication of effort by regulators and health technology assessment bodies. In both arenas, drug-makers are faced with mounting drug development costs, and uncertainty over the types of evidence acceptable for a growing list of stakeholders. This article reports and compares future scenarios for evidence expectations for drugs for the USA and EU in 2020. The similarities, differences, and joint implications of the scenarios are considered to create an view of future evidence generation for drugs developed for these markets.

Futurescapes: evidence expectations in the USA for comparative effectiveness research for drugs in 2020

AIM Explore key factors influencing future expectations for the production of evidence from comparative effectiveness research for drugs in the USA in 2020 and construct three plausible future scenarios. MATERIALS & METHODS Semistructured key informant interviews and three rounds of modified Delphi with systematic scenario-building methods. RESULTS & CONCLUSION Most influential key factors were: health delivery system integration; electronic health record development; exploitation of very large databases and mixed data sources; and proactive patient engagement in research. The scenario deemed most likely entailed uneven development of large integrated health systems with pockets of increased provider risk for patient care, enhanced data collection systems, changing incentives to do comparative effectiveness research and new opportunities for evidence generation partnerships.
