Extract

Translational science is a 21st century mission. Government officials and industry leaders are making huge investments in an attempt to transform more basic science discoveries into therapeutic applications. Scientists and policymakers express great excitement about the medical advances that could come with the current bench-to-bedside campaign.

A key step in translational science is the move from animal and other preclinical studies to initial human testing. Researchers ability to predict human effects is limited, and first-in-human (FIH) tests present significant uncertainty. Participants in this form of research face risks and can experience serious, even lethal, harm. Well-known incidents involving Jolee Mohr and Jesse Gelsinger, as well as subjects in the 2006 study of the investigational agent TGN1412, show the dangers that can arise in early human research.

The bench-to-bedside campaign will need many volunteers to participate in early human testing. Investigators and regulators must not allow the policy enthusiasm for translational science to overshadow the commitment to protect human subjects. Participants in exploratory research are diverse and as a group lack characteristics usually associated with vulnerable populations, such as impaired decisional ability or economic or educational disadvantage.

It is not clear that this approach will improve the risk-benefit ratio, however. A review of oncology trials published between 2002 and 2004 found that such design strategies were not associated with increased response rates and that subjects in such trials were at greater risk of experiencing severe or life-threatening toxicity.

The therapeutic misconception arises when research participants confuse the objective of research, which is to generate knowledge, with the objective of therapy, which is to benefit the individual patient. In this situation, some may enroll in studies with the mistaken belief that each study component is aimed at patient care, rather than knowledge production. See Henderson, G. E., “Clinical Trials and Medical Care: Defining the Therapeutic Misconception,” PLoS Medicine 4, no. 11 (2007): e324, available at <http://medicine.plosjournals.org/perlserv/?request=get-document&doi=10.1371/journal.pmed.0040324&ct=1> (last visited November 20, 2008). In a discussion of translational science, one group advises scientists to “learn to articulate not only the promise of science, but also the difficulties that are associated with moving an idea along to the product stage, so that unrealistic expectations of perfect medicines for every disease in short time frames are not raised.” See Sabroe, , supra note 31, at 79.CrossRefGoogle Scholar
