Patent

CA 2271689

The present invention relates to a radiolabeled DNA carrier, a method of preparation thereof and the therapeutic uses of this substance to prevent uncontrolled cellular proliferation. The invention also relates to devices incorporating the above radiolabeled DNA carrier (such as an oligonucleotide) for the therapeutic treatment of uncontrolled cellular proliferation. More specifically, the present invention is concerned with the prevention of restenosis by intravascular delivery of radiolabeled DNA carrier at a dilatation site of an artery. This invention is also directed to a method of treatment of vascular proliferative diseases and/or other proliferative disorders such as cancer and related metastasis. More particularly, the invention relates to the preparation of DNA sequences carrying one or several radioisotopes, located within the DNA sequence, and which are able to prevent cell proliferation in vitro and, pursuant to local drug delivery and/or systemic drug delivery, are able to prevent cell proliferation in vivo, more particularly restenosis and malignant tumors. In other words, the invention relates to the synthesis process, the stability data of the radiolabeled DNA carrier, the efficacy of the invention in vitro, in cell culture, and the in vivo delivery of the molecule.

La présente invention concerne un support d'ADN radiomarqué, un procédé de préparation associé ainsi que des utilisations thérapeutiques de cette substance, servant à prévenir une prolifération cellulaire non régulée. L'invention concerne également des dispositifs incorporant ce support d'ADN radiomarqué (tel qu'un oligonucléotide), aux fins de traitement thérapeutique de la prolifération cellulaire non régulée. Plus précisément, cette invention concerne la prévention de la resténose par apport intravasculaire du support d'ADN radiomarqué, au niveau d'un site de dilatation d'une artère. Cette invention concerne encore un procédé de traitement de maladies à prolifération vasculaire et/ou d'autres troubles prolifératifs, tels que le cancer et les métastases associées, et elle concerne notamment la préparation de séquences d'ADN portant un ou plusieurs radio-isotopes, situés dans la séquence d'ADN et qui peuvent empêcher la prolifération cellulaire in vitro et, après apport local et/ou systémique de médicament, peuvent empêcher la prolifération cellulaire in vivo, notamment la resténose et les tumeurs malignes. En d'autres termes, l'invention concerne le procédé de synthèse, les données de stabilité du support d'ADN radiomarqué, l'efficacité de l'invention in vitro, dans une culture cellulaire, et l'apport in vivo de la molécule.
