Africa-Press – Togo. <\/strong> <\/span>Le Japon a approuve\u0301 la commercialisation de produits de me\u0301decine re\u0301ge\u0301ne\u0301rative par cellules souches contre des maladies cardiaques et la maladie de Parkinson, ont indique\u0301 le 6 mars 2026 l’un des fabricants et des me\u0301dias. Le laboratoire pharmaceutique Sumitomo Pharma a annonce\u0301 avoir rec\u0327u l’autorisation de fabriquer et commercialiser Amchepry, traitement contre la maladie de Parkinson consistant a\u0300 transplanter des cellules souches dans le cerveau.<\/p>\n

Selon des me\u0301dias, le ministe\u0300re japonais de la Sante\u0301 a e\u0301galement donne\u0301 son feu vert a\u0300 ReHeart, de\u0301veloppe\u0301 par la start-up me\u0301dicale Cuorips: le traitement consiste en des pellicules de muscle cardiaque place\u0301es a\u0300 la surface du c\u0153ur, ou\u0300 elles provoquent la formation de nouveaux vaisseaux sanguins et aident a\u0300 restaurer la fonction cardiaque.<\/p>\n

Ces traitements pourraient e\u0302tre propose\u0301s aux patients de\u0300s cet e\u0301te\u0301, d’apre\u0300s des sources citant le ministe\u0300re. Il s’agira des premiers produits me\u0301dicaux disponibles sur le marche\u0301 a\u0300 utiliser des cellules iPS (cellules souches pluripotentes induites).<\/p>\n

Cette innovation re\u0301compense\u0301e par un prix Nobel<\/b><\/p>\n

La recherche sur cette innovation, qui consiste a\u0300 transformer une cellule adulte spe\u0301cialise\u0301e en une cellule immature capable de se de\u0301velopper en n’importe quelle sorte de cellule de l’organisme, a valu le prix Nobel de me\u0301decine 2012 au chercheur japonais Shinya Yamanaka. \u00ab\u00a0J’espe\u0300re que cela apportera un soulagement aux patients, non seulement au Japon, mais dans le monde entier\u00a0\u00bb, a de\u0301clare\u0301 le ministre de la Sante\u0301, Kenichiro Ueno, lors d’une confe\u0301rence de presse.<\/p>\n

Dans un communique\u0301, Sumitomo Pharma a annonce\u0301 avoir obtenu une autorisation de mise sur le marche\u0301 \u00ab\u00a0conditionnelle et temporaire\u00a0\u00bb pour la fabrication et la commercialisation d’Amchepry, un dispositif conc\u0327u pour acce\u0301le\u0301rer l’acce\u0300s des patients a\u0300 ce produit.<\/p>\n

Autorisation obtenue apre\u0300s un essai sur sept patients<\/b><\/p>\n

Cette autorisation fait suite a\u0300 une e\u0301valuation de l’innocuite\u0301 et de l’efficacite\u0301 du traitement sur la base de donne\u0301es recueillies aupre\u0300s d’un nombre de patients plus restreint que lors d’essais cliniques classiques.<\/p>\n

Ainsi, un essai mene\u0301 par des chercheurs de l’Universite\u0301 de Kyoto a porte\u0301 sur sept patients atteints de la maladie de Parkinson, a\u0302ge\u0301s de 50 a\u0300 69 ans, ayant rec\u0327u chacun cinq ou dix millions de cellules implante\u0301es de part et d’autre du cerveau. Les cellules iPS, issues de donneurs sains, ont e\u0301te\u0301 diffe\u0301rencie\u0301es en pre\u0301curseurs de neurones dopaminergiques, absents chez les personnes atteintes de la maladie de Parkinson.<\/p>\n

Les patients ont e\u0301te\u0301 suivis pendant deux ans et l’e\u0301tude n’a re\u0301ve\u0301le\u0301 aucun effet inde\u0301sirable majeur. Quatre patients ont pre\u0301sente\u0301 une ame\u0301lioration de leurs sympto\u0302mes.<\/p>\n

La maladie de Parkinson est une affection neurologique chronique et de\u0301ge\u0301ne\u0301rative qui touche le syste\u0300me moteur. Selon Parkinson’s Foundation, environ 10 millions de personnes dans le monde sont atteintes. Les traitements actuellement disponibles \u00ab\u00a0ame\u0301liorent les sympto\u0302mes sans toutefois ralentir ni stopper la progression de la maladie\u00a0\u00bb, pre\u0301cise la fondation.<\/p>\n
