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.
