International audience. Human cytomegalovirus (HCMV) is one of the most important causes of complications in immunocompromised patients and congenital infections. HCMV could also represent an interesting target for treatment to limit the progression of glioblastoma, a highly aggressive tumor. Ganciclovir, foscarnet and cidofovir, which interfere with the activity of the viral polymerase pUL54, are widely used in the treatment of transplant patients. However, their use in pregnant women remains limited or even contraindicated. On the other hand, hyperimmune immunoglobulins and valaciclovir have been shown to have a protective effect on the fetus. However, the toxicity of these treatments and the emergence of resistance mean that new therapeutic strategies need to be identified. Letermovir and maribavir have been developed to inhibit new targets, respectively the terminase complex and UL97 protein kinase. Their respective indications are the prevention of HCMV infection in haematopoietic stem cell transplant patients and the treatment of refractory HCMV infections. Finally, with the development of mRNA vaccines, the hope of one day seeing a prophylactic HCMV vaccine has never been greater. New therapeutic approaches are also being explored, but they still require extensive preclinical and clinical evaluation.
