Calls are increasing for manufacturers to provide evidence of comparative efficacy of new drugs at the time of regulatory approval.1 However, drug manufacturers maintain that doing so would create unrealistically high barriers for market entry and deter innovation. At a time of a perceived productivity crisis in the drug industry, many claim that stricter market authorisation regulation will be detrimental to the development of new drugs.2 We review the historical effect of regulating market authorisation and examine the benefits and risks of raising evidence standards by requiring evidence of non-inferiority for market entry.
What’s the hype?
Various components of drug development, including experimentation, evidence generation, and marketing are already subject to regulation. However, there is interest in expanding the remit of regulatory agencies in Europe and the United States in order to make drug manufacturers more accountable and market authorisation more stringent.3 Recent proposals include making the raw data collected in pivotal randomised controlled trials of new drugs publicly available and developing a framework for independent appraisal of evidence.
One particularly important aspect is the standards of evidence for marketing authorisation.4 Currently, each new product is evaluated on its own merit, without being assessed against other available treatments. As a result, many drugs are approved on the basis of placebo controlled trials without showing their equivalence, non-inferiority, or superiority to existing alternatives. There are proposals in the United States and Europe to require evidence on comparative efficacy at the time of licensing.1 5 This is because the current regulatory environment crowds the marketplace with products that offer marginal, if any, improvements in therapeutic value over existing options. …
