摘要
Introduction: Refractory or resistant cytomegalovirus (CMV) infection and disease pose a significant challenge in immunocompromised patients, including solid organ transplant (SOT) and allogeneic hematopoietic cell transplant (allo-HCT) recipients. This study aimed to evaluate letermovir as a treatment for patients with CMV infection or disease.Methods: We performed an open-label, phase II non-randomized clinical trial. Adult and pediatric (>= 12 years of age) patients who had undergone an SOT or allo-HCT and who required antiviral treatment for refractory or resistant CMV or who had CMV with concurrent organ dysfunction were eligible. Patients received letermovir treatment daily for up to 12 weeks with an optional additional 12 weeks of therapy for secondary prophylaxis if clinically indicated. The primary objectives were to evaluate the safety and efficacy of letermovir treatment based upon virological and clinical responses.Results: Ten patients were enrolled in the study and seven patients completed the study treatment and follow-up period. The overall virological response (defined as a complete virological response at the end of the study period) rate was 60% in the study population. The study drug was well tolerated as only two patients experienced study drug-related toxicity and only one grade 3 toxicity (elevated ALT) was observed. Letermovir was not associated with acute kidney injury, hepatotoxicity, cardiac arrhythmias, or bone marrow suppression.Conclusion: In this limited sample, letermovir for CMV treatment was safe and well tolerated. Further research is needed to determine if letermovir can be used for the treatment of refractory or resistant CMV infection or disease. Introduction : L'infection et la maladie & agrave; cytom & eacute;galovirus (CMV) r & eacute;fractaires ou r & eacute;sistantes sont particuli & egrave;rement difficiles & agrave; traiter chez les patients immunod & eacute;prim & eacute;s, y compris les receveurs d'une transplantation d'organe plein (TOP) ou d'une allogreffe de cellules souches h & eacute;matopo & iuml;& eacute;tiques (allo-CSH). La pr & eacute;sente & eacute;tude visait & agrave; & eacute;valuer le traitement au l & eacute;termovir pour les patients atteints d'une infection ou d'une maladie & agrave; CMV.M & eacute;thodologie : Les chercheurs ont r & eacute;alis & eacute; une & eacute;tude clinique non randomis & eacute;e ouverte de phase II. Les patients adultes et adolescents (12 ans ou plus) qui avaient subi une TOP ou une allo-CSH et qui avaient besoin d'un traitement antiviral & agrave; cause d'un CMV r & eacute;fractaire ou r & eacute;sistant ou qui & eacute;taient atteints d'un CMV conjointement & agrave; un dysfonctionnement d'organe y & eacute;taient admissibles. Les patients ont re & ccedil;u un traitement au l & eacute;termovir tous les jours pendant une p & eacute;riode maximale de 12 semaines, suivi d'une p & eacute;riode suppl & eacute;mentaire facultative de 12 semaines en prophylaxie secondaire si leur & eacute;tat clinique l'indiquait. Les objectifs primaires consistaient & agrave; & eacute;valuer l'innocuit & eacute; et l'efficacit & eacute; du traitement au l & eacute;termovir en fonction des r & eacute;ponses virologique et clinique.R & eacute;sultats : Dix patients ont particip & eacute; & agrave; l'& eacute;tude et sept d'entre eux ont termin & eacute; la p & eacute;riode de traitement et de suivi. Au total, 60 % de la population & agrave; l'& eacute;tude a pr & eacute;sent & eacute; une r & eacute;ponse virologique globale (d & eacute;finie comme une r & eacute;ponse virologique compl & egrave;te & agrave; la fin de l'& eacute;tude). Le m & eacute;dicament & agrave; l'& eacute;tude & eacute;tait bien tol & eacute;r & eacute;, puisque seulement deux patients ont pr & eacute;sent & eacute; une toxicit & eacute; reli & eacute;e au m & eacute;dicament, y compris un seul cas de toxicit & eacute; de grade 3 (ALT & eacute;lev & eacute;). Le l & eacute;termovir n'& eacute;tait pas associ & eacute; & agrave; une insuffisance r & eacute;nale aigu & euml;, & agrave; une h & eacute;patotoxicit & eacute;, & agrave; des arythmies cardiaques ni & agrave; une d & eacute;pression m & eacute;dullaire.Conclusion : Dans cet & eacute;chantillon limit & eacute;, le l & eacute;termovir & eacute;tait s & eacute;curitaire et bien tol & eacute;r & eacute; pour traiter le CMV. D'autres recherches devront & ecirc;tre r & eacute;alis & eacute;es pour d & eacute;terminer s'il peut & ecirc;tre utilis & eacute; pour le traitement de l'infection ou de la maladie & agrave; CMV r & eacute;fractaire ou r & eacute;sistante.
