The third CMR Workshop prov. ided the opportunity for a group of experts
from the Industry, academia and the regulatory authorities to meet and
discuss ways and means by which risk benefit decisions are made during
the various stages of drug development. It became apparent from the
discussions that took place in October 1985, at the CIBA Foundation,
that decisions are often made with limited data and inadequate
methodology. The conclusions drawn from the day's deliberations were as
follows: 1. Current methodology for assessing risk and particularly
benefits must be improved; 2. Safety must be assessed in association
with benefits as it is ultimately the benefit/ risk ratio which should
decide the future of medicines; 3. Risks from medicines must always be
viewed in relation to the risks from untreated diseases. It seemed to be
the consensus of the group that such a meeting was both useful and
informative and, hopefully, the publication of these proceedings will
stimulate further discussion in this important area which may improve
the decision-making process in drug development. The Editors wish to
thank the participants for contributing to the Work- shop, together with
Dr. Cyndy Lumley for providing the initial transcript of the meeting and
Mrs Sheila Wright for producing the final version and for carrying out
all the additional work that is entailed in producing such a
publication. Professor S. R. Walker A. W.
