A New Paradigm for Clinical Development:
The Clinical Trial in 2015
A New Paradigm for Clinical Development: The Clinical Trial in 2015 outlines
an innovative and imaginative strategy for reinventing clinical development,
and demonstrates why a complete overhaul of the clinical trials process is
feasible from a conceptual, technical and logistical point of view.
The current clinical evaluation process is fraught with inefficiencies,
resulting in numerous compound failures and exploding development costs. Until
recently, the industry has reacted to the clinical evaluation problem
essentially by "streamlining" the existing processes and by introducing
information technology in a cautious and evolutionary fashion. While the FDA's
Critical Path Initiative of 2004 showed that the agency is willing to take the
lead in working with representatives from industry and academia towards a
remedy, this report suggests that a more radical solution is needed.
A New Paradigm for Clinical Development: The Clinical Trial in 2015 proposes a
bidirectional approach to accelerate the clinical process and make it more
effective. These two avenues, which can be summarized as revamping trial
design and as truly pervasive modelling and monitoring driven by information
technology, are fundamentally different from each other but need to be
implemented in a closely linked fashion. Though radical in effect, none of
these changes would involve concepts or technologies that are unknown today.
According to the strategy laid out in the report, the following changes are
required:
- Phase I will assume a new role as a brief confirmatory testing stage for
the model for drug-human interactions that the sponsor has proposed.
- Phases II and III will merge into a single advanced-stage human testing
phase involving fewer patients than today, relying on relatively small patient
populations that are highly homogenous with respect to key criteria of
pharmacological response.
- Systematic post-marketing studies and a significantly improved and
extended post-marketing surveillance system that goes far beyond adverse event
reporting will be integrated into a post-marketing monitoring phase that
documents real-life use of the newly licensed drug.
These new processes will be made possible through holistic mathematical models
such as the virtual patient, extensive biomarker monitoring, and pervasive
computing. With a full implementation of all envisaged changes by the year
2015, the stage would be set for a new world of drug development:
- The pre-approval clinical trial phase might be shortened to about three
years and 40-50 percent of all candidate compounds that enter this stage could
complete it, with the majority of the failures occurring in the early human
validation phase.
- The crucial function of the advanced-stage human testing phase will be to
determine whether efficacy is sufficiently superior over the established
standard of therapy to warrant the cost of launch and the mandated
post-marketing monitoring.
- Developers recoup development costs earlier and enjoy a longer life cycle
under patent protection, but also benefit from more and closer attention to
real-life use of the newly licensed drug.
