Report: Health Economics Outcomes are Rarely Considered in Adaptive Clinical Trial Designs

Opportunities Are Potentially Being Missed to Improve Healthcare Decision Making

Lawrenceville, NJ, USA—April 30, 2019—Value in
Health
, the
official journal of ISPOR—the
professional society for health economics and outcomes research, announced
today the publication of new research showing that consideration is rarely
given to the health economic analysis of adaptive clinical trials. As a result,
opportunities to use health economic outcomes in the design and analysis of adaptive
trials are being missed. The paper, “A
Review of Clinical Trials With an Adaptive Design and Health Economic Analysis
,” was published in the April 2019 issue of Value
in Health

Both
health economics and adaptive designs aim to enable efficient and accurate decision
making. Health economic analysis facilitates the
comparison of the costs and benefits of alternative technologies to determine which
is the most cost-effective. Adaptive designs use data collected as a trial
progresses to inform modifications to the trial without compromising the
validity or integrity of the study. However, while adaptive designs have the
potential to benefit patients and healthcare providers and are becoming a
popular alternative to the traditional fixed sample size trial in appropriate
clinical circumstances, they could impact accuracy by introducing bias into
health economic analyses. It has been unclear, historically, whether the methods
are typically considered together in the design, analysis, and reporting of
trials.

To
establish how often and effectively health economic outcomes are used in the
design, analysis, and reporting of clinical trials that have adaptive designs,
the authors assessed the results of such trials registered and published up to August
2016. A total of 553 articles were identified. Of these, 37 trials met the
inclusion criteria and were subject to full data extraction.

In
the review of these 37 clinical trials, 3 used health economic outcomes in the
design, and none seemed to appropriately adjust the health economic outcomes,
where thought to be required, to account for biases introduced by the adaptive
study design. Of the 19 trials with results, 1 used health economic outcomes at
the interim analysis. The reporting of health economic results was suboptimal for
17 of the 19 trials with published results.

“Using
health economics and adaptive designs together could help us make healthcare
decisions more efficiently and save scarce resources,” said author Laura
Flight, School of Health and Related Research (ScHARR), University of
Sheffield, Sheffield, England, United Kingdom. “Before this approach is used in
practice it is important to have a clear understanding of how adaptive designs
and health economics are used together in the design, analysis, and reporting
of clinical trials. Our review has shown that further work is needed to
establish whether adaptive designs and health economic analyses can be used
together to increase the efficiency of health technology assessments without compromising
accuracy.”

The
study was funded by the National Institute for Health Research Doctoral Research Fellowship Programme (Grant
Reference Number DRF-2015-08-013). The views expressed are those of the authors
and not necessarily those of the NIHR or the Department of Health and Social
Care.
