Definitions

  • the present invention relates to the field of drug administration, in particular the field of in situ postoperative drug administration.
  • tumor ablation can be one of the most effective one, depending on the case and on the cancer type.
  • a given sponge can administrate only one drug, whereas the treatment of a tumor is more efficient when combining the effects of several drugs.
  • An object of the invention is therefore to provide a biocompatible patch which can be applied and fixed upon a zone to be treated after a surgery, typically an ablated zone, so as to release medications consisting in several drugs, preferably tailored to the tumor which is to be treated with the patch.
  • a multilayer patch for therapeutic use comprising:
  • a biocompatible carrier layer A first polymeric layer comprising a first drug, and
  • a second polymeric layer comprising a second drug, wherein the first drug is different from the second drug.
  • the multilayer patch according to the present invention can be manufactured on demand on a patient per patient basis so as to provide a tailored treatment, opening the way for personalized medicine.
  • the drugs contained on the multilayer patch can diffuse over a few millimeters in the tissues on which the patch is applied and treat the corresponding zone.
  • Using a local treatment allows for high concentration of drugs and corresponding greater efficiency of the treatment.
  • Such high concentrations cannot be used when the drugs are administrated through the general circulation. Indeed, in conventional practices, drug is systematically injected intravenously and then by binding to cytoskeleton, DNA strains, or other drug targets it results in the formation of various defects in DNA molecules, forcing the cell to undergo apoptotic death path.
  • the multilayer patch according to the present invention allows circumventing this issue.
  • the multilayer patch is particularly suited for all post-surgery residual tumor treatment consecutive to pelvis surgery and abdomen surgery, particularly in case of liver or pancreas cancer.
  • At least one layer of the multilayer patch according to the present invention may be tailored by undergoing processes selected from grafting and copolymerization.
  • the biocompatible carrier layer serves both as a mean for facilitating the acceptance of the patch in the body, as a mean for controlling the release rate of the drugs - the thicker the carrier layer, the slower the release - and as a mean for controlling the adherence of the patch.
  • the biocompatible carrier layer is preferably auto-adhesive. It can be provided together with a protection layer which is to be removed before used. If the biocompatible carrier layer is not auto-adhesive, it can be attached to the desired zone with any suitable means such as suture points.
  • the multilayer patch can be coupled with 3D impression processes with e.g. PLA or other nontoxic mono/polymers so as to better correspond to the shape of the zone to be treated.
  • the biocompatible carrier layer is designed so as to be easily distinguished over the other side of the patch.
  • Such distinction can take the form of a printing, of a different color, of a different texture, or any other suitable means.
  • the biocompatible carrier layer is preferably a medium which is permeable to the drugs and which allows their diffusions there through.
  • a preferred material for the biocompatible carrier layer is collagen, fibrin or any commercial biocompatible substrates such as Steralloy films (HAPCO), a bi- component commercial elastomer or even biocompatible PU.
  • HAPCO Steralloy films
  • collagen membranes are widely used in post-surgery treatments to provide isolation of operated zone, preventing adhesion of internal organs and scar tissue and intended to promote tissue regeneration. Such membranes thus represent an excellent base for drug delivery systems.

Abstract

La présente invention concerne le domaine de l'administration de médicament, en particulier le domaine de l'administration de médicament post-opératoire in situ. Parmi les nombreuses options disponibles pour lutter contre le cancer, l'ablation de tumeur peut être la plus efficace, en fonction du cas et du type de cancer. Cependant, il existe certains cas dans lesquels les cellules tumorales résiduelles laissées après l'ablation peuvent ensemencer la propagation d'une nouvelle tumeur après. L'invention fournit une manière d'adresser ce problème et concerne un patch multicouche comprenant : - une couche de support biocompatible, - une première couche polymère comprenant un premier médicament, et - une seconde couche polymère comprenant un second médicament, le premier médicament étant différent du second médicament. En particulier, les inventeurs ont testé l'invention dans le cas de cancers du pancréas qui s'avèrent particulièrement utiles.
