          Abstract

          Resumo: O presente artigo se propõe a discutir as muitas complexidades envolvidas na incorporação de novas tecnologias em saúde para doenças raras, tomando como foco central da discussão o caso da fibrose cística. Tal escolha acontece por ser essa uma doença rara, genética, autossômica recessiva, considerada a mais comum entre as doenças raras. Também por ser uma doença que tem se beneficiado imensamente dos investimentos em pesquisa no campo da biologia molecular, feitos principalmente nos Estados Unidos, mas também em grupos de pesquisa europeus que resultaram no registro e comercialização de quatro novos medicamentos. Esses novos fármacos atuam, pela primeira vez, no defeito básico da fibrose cística. Numa perspectiva que entende as doenças raras como um campo de pesquisa tecido entre muitos outros, o presente texto tenta problematizar, com base em uma perspectiva mais centrada nas pessoas com fibrose cística, a dualidade de testemunhar de longe a molecularizaçao da vida, o surgimento de medicamentos de última geração que interrompem, em nível molecular, a cascata de erros e portanto sintomas e evolução de sua doença. O texto busca trazer para o debate os vários elementos que atravessam a complexa realidade local dos pacientes brasileiros com fibrose cística, num contexto global de inovação tecnológica e de quebra de paradigma em seus tratamentos. Baseando-se no campo das doenças raras, passando pela apresentação da fibrose cística em tempos da medicina de precisão, aliado a discussões sobre biopolíticas num contexto de inovação em saúde e medicamentos de alto custo, o artigo tenta dar visibilidade aos desafios e possibilidades do tempo presente.

          Translated abstract

          Abstract: The article proposes to discuss the many complexities involved in the incorporation of new health technologies for rare diseases, with a central focus on the case of cystic fibrosis. Cystic fibrosis was chosen because it is a autosomal recessive genetic disorder, considered the most common of the rare diseases. The disease has also benefited greatly from investments in research in the field of molecular biology, mainly in the United States, but also among European research groups, which resulted in the registration and marketing of four new drugs. These new drugs act for the first time on the basic defect in cystic fibrosis. From a perspective that views rare diseases as a field of research woven among many others, the article aims to problematize cystic fibrosis from a more person-centered approach, the duality of witnessing from afar the molecularization of life, the emergence of last-generation drugs that interrupt, at the molecular level, the cascade of errors and thus the symptoms and evolution of the disease. The article aims to bring various elements to the debate that traverse the complex local reality of Brazilian cystic fibrosis patients in a global context of technological innovation and with a break in the treatment paradigm. Based on the field of rare diseases, including the presentation of cystic fibrosis in the age of precision medicine, alongside discussions on biopolitics in a context of health innovation and high-cost drugs, the article aims to shed light on the current challenges and possibilities.

          Elexacaftor–Tezacaftor–Ivacaftor for Cystic Fibrosis with a Single Phe508del Allele

          Cystic fibrosis is caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) protein, and nearly 90% of patients have at least one copy of the Phe508del CFTR mutation. In a phase 2 trial involving patients who were heterozygous for the Phe508del CFTR mutation and a minimal-function mutation (Phe508del-minimal function genotype), the next-generation CFTR corrector elexacaftor, in combination with tezacaftor and ivacaftor, improved Phe508del CFTR function and clinical outcomes.

            Identification of the cystic fibrosis gene: cloning and characterization of complementary DNA

            Overlapping complementary DNA clones were isolated from epithelial cell libraries with a genomic DNA segment containing a portion of the putative cystic fibrosis (CF) locus, which is on chromosome 7. Transcripts, approximately 6500 nucleotides in size, were detectable in the tissues affected in patients with CF. The predicted protein consists of two similar motifs, each with (i) a domain having properties consistent with membrane association and (ii) a domain believed to be involved in ATP (adenosine triphosphate) binding. A deletion of three base pairs that results in the omission of a phenylalanine residue at the center of the first predicted nucleotide-binding domain was detected in CF patients.

              Cystic fibrosis genetics: from molecular understanding to clinical application.

              The availability of the human genome sequence and tools for interrogating individual genomes provide an unprecedented opportunity to apply genetics to medicine. Mendelian conditions, which are caused by dysfunction of a single gene, offer powerful examples that illustrate how genetics can provide insights into disease. Cystic fibrosis, one of the more common lethal autosomal recessive Mendelian disorders, is presented here as an example. Recent progress in elucidating disease mechanism and causes of phenotypic variation, as well as in the development of treatments, demonstrates that genetics continues to play an important part in cystic fibrosis research 25 years after the discovery of the disease-causing gene.
