Abstract
L’inhibiteur d’intégrase dolutégravir (DTG), qui a été récemment approuvé pour le traitement des personnes vivant avec le VIH, un des très rares médicaments contre le VIH qui n’ait pas conduit à l’émergence de mutations de résistance lorsqu’il est utilisé en traitement de première ligne. Dans cet article, nous avançons l’hypothèse que l’absence de sélection de mutants résistants est due à la diminution de la capacité de réplication des virus résistant à DTG et que le DTG pourrait ainsi être utilisé dans des stratégies curatives.
The HIV integrase inhibitor, Dolutegravir (DTG), was recently approved by the Food and Drug Administration in the United States and is the only HIV drug that has not selected for resistance mutations in the clinic when used as part of first-line therapy. This has led to speculation that DTG might have a higher genetic barrier for the development of drug resistance than the other compounds that are used in therapy. In this Opinion article, we speculate that this is due to greatly diminished replication capacity on the part of viruses that might become resistant to DTG when the drug is used in initial therapy and that DTG might be able to be used in HIV prevention and eradication strategies. We also note that no compensatory mutation that might restore viral replication fitness to HIV in the aftermath of the appearance of a single drug resistance mutation has yet been observed. In conclusion, DTG is a valuable addition to the anti-HIV armamentarium of drugs and its long-term utility may potentially exceed its obvious use in treatment of HIV disease.
