Use of the foreign studies : Transposition of the results, prediction of the therapeutic effects in the French population, modelling of the public health interest

More and more frequently, the health authorities and the French assessment agencies are led to issue Marketing Authorizations (MAs), give opinions on the eligibility for reimbursement of drugs or to draft recommendations for clinical practice based on the results of foreign studies. The results of these studies are more or less difficult to transpose to French practice. These difficulties generate varying degrees of uncertainty concerning the effect to be expected of a drug. A more or less extensive loss of effect is sometimes even predictable. Some of the difficulties in transposition are discussed in this article and proposals for action are made in order to allow one, in the long term, to predict in the most precise manner possible the effects to be expected from a drug in the French population and be able to verify this prediction at an interval from its eligibility for reimbursement.

Scientific Evaluation and Pricing of Medical Devices and Associated Procedures in France

Medical devices are many and various, ranging from tongue spatulas to implantable or invasive devices and imaging machines; their lifetimes are short, between 18 months and 5 years, due to incessant incremental innovation; and they are operator-dependent: in general, the clinical user performs a fitting procedure (hip implant or pacemaker), a therapeutic procedure using a non-implantable invasive device (arrhythmic site ablation probe, angioplasty balloon, extension spondyloplasty system, etc.) or follow-up of an active implanted device (long-term follow-up of an implanted cardiac defibrillator or of a deep brain stimulator in Parkinsons patients). A round-table held during the XXVIII(th) Giens Workshops meeting focused on the methodology of scientific evaluation of medical devices and the associated procedures with a view to their pricing and financing by the French National Health Insurance system. The working hypothesis was that the available data-set was sufficient for and compatible with scientific evaluation with clinical benefit. Post-registration studies, although contributing to the continuity of assessment, were not dealt with. Moreover, the focus was restricted to devices used in health establishments, where the association between devices and technical medical procedures is optimally representative. An update of the multiple regulatory protocols governing medical devices and procedures is provided. Issues more specifically related to procedures as such, to non-implantable devices and to innovative devices are then dealt with, and the proposals and discussion points raised at the round-table for each of these three areas are presented.
