The need for development of a clinical trial guidance for medicines for bronchial asthma is brought about by the im- provement of requirements for research programmes for new medicines. The aim of the study was to develop a methodological approach to conducting clinical trials of bronchial asthma medicines in Russia in line with the existing international requirements. The authors analysed regulatory documentation on the development of medicines for treatment of bronchial asthma in adults tak-ing into account the current clinical guidelines, and specific aspects of developing medicines for treatment of bronchial asthma in children. The paper also analyses some clinical research aspects related to the development of immunotherapy. The analysis of up-to-date Russian and international clinical guidelines for bronchial asthma treatment, which are focused on bronchial asthma management using basic therapy, revealed the need to use revised disease concepts and new criteria to assess the efficacy of asthma medicines. The authors formulated consistent approaches to planning a clinical development programme for medicines for bron- chial asthma, and suggested methodology for conducting clinical research based on recommendations of the European Medicines Agency. астмы (Global Initiative for Asthma, GINA; Global Strategy for Asthma Management and Prevention).","PeriodicalId":22286,"journal":{"name":"The Bulletin of the Scientific Centre for Expert Evaluation of Medicinal Products","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81290921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study covered stability testing of small-molecule medicines. The paper describes evolution of approaches to stability testing in the Russian Federation. It summarises the main differences in basic requirements for stability testing as stipulated in the State Pharmacopoeia of the Russian Federation (Ph. Rus.) XIII edition, Ph. Rus.

The study demonstrated that the Russian Federation lacks regulations containing specific requirements for stability testing performed to support variations to marketing authorisation documentation. The Ph. Rus. XIV edition does not specify the extent of stability testing to be performed after switching to another manufacturer of the active ingredient or introduction into operation of a new manufacturing site where the medicinal product will be produced. At the same time, the EAEU regulatory documents contain requirements for stability testing for each type of the most frequent variations to marketing authorisation documentation. The study demonstrated the continuing relevance of bringing the Russian regulations on stability testing in line with those of the EAEU.","PeriodicalId":22286,"journal":{"name":"The Bulletin of the Scientific Centre for Expert Evaluation of Medicinal Products","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90631623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
