title: Clinical research on new drugs (Phase I). Profile of scientific publications: data from the pre-clinical phase and bioethical aspects.
abstract: OBJECTIVE
  To trace a profile of scientific publications, phase I, in order to know whether or not they show pre-clinical phase data, emphasizing bioethical aspects.
  
  
  METHODS
  Sixty-one scientific articles, published in 2007, involving research in human beings using new drugs, medicines and vaccines during phase I were analysed. A schedule for data collection was elaborated in which it would be possible to analyse and evaluate those articles. The schedule included items related to the pre-clinical phase associated to the clinical phase, and items related to the sample characteristics.
  
  
  RESULTS
  Most of research works were carried out in USA. Taking into consideration that a large number of works have been dedicated to oncologic affections, most of them were carried out in voluntary ill individuals. Information on the pre-clinical phase, phase I, was very poor or absent. Even though some authors consider the phase I research as a promising one and also suggest some future studies on phase II, the reader is not able to consider the same way, as long as there is a shortage of information on the pre-clinical phase.
  
  
  CONCLUSIONS
  The profile of scientific publications showed that data deserve some reflections and analysis to better evaluate the publications on phase I.
