title: Multiple-dose phase I trials--normal volunteers or patients? One viewpoint.
abstract: Traditionally, Phase I tolerance trials have been done with normal volunteers to establish single- and multiple-dose tolerance. We feel that the justification for doing multiple-dose tolerance studies in normals is open to question and that, in fact, more pertinent data can be generated by using the appropriate patient populations for these studies.
