Overview

Currently, there are no specific therapies targeting EV-D68. Athough the management of enteroviruses in general is only supportive, the development of pharmacological therapies recently emerged. Immune globulin therapy has demonstrated clinical and laboratory benefit among some patients with enterovirus infection. Antiviral medications against enteroviruses, such as pleconaril, are currently being studied for patients with severe infections caused by other subtypes of enteroviruses.

Future or Investigational Therapies

Immune globulin

  • Studies in neonates with enterovirus infection suggest a possible benefit of the administration of immune globulin[1][2], however, more studies need to be done do confirm the benefit of this treatment.
  • The development of IVIg with high levels of enterovirus antibody has shown benefit in in vitro and mouse models studies for enterovirus subtype 71. However, this has not been studied for EV-D68.[3]

Antiviral Medication

  • There are no antiviral medications that specifically target EV-D68 only. Instead, antiviral medications against enteroviruses in general are also believed to be able to successfully target EV-D68.
  • Pleconaril has shown benefit among patients with severe life-threatening enterovirus infections. This antiviral drug prevents the attachment of the virus to the host cell and integration of its RNA to the host DNA.[4]
  • The table shown below describes the possible targets for antiviral treatment against enterovirus infections.[5][6]
Target Antiviral Drugs
Protease 2A or 3C Rupintrivir, Br-UTP, AG7088 derivative
Capsid binders Pleconaril, Pirodavirb, pyridazinyl oxime ethersb (BTA-39c), pyridyl imidazolidinonesc; NF-449c, V-073
RNA replication (2C and 3B protein) Enviroxime, TTP-8307, vinylacetylene analogs, GW5074c, Benzimidazoles, N(6)-benzyladenosine, metrifudil
RNA-dependent RNA polymerase 2′C–Me-cytidine, 4′-azidocytidine, 2′C-ME-adenosine, ribavirin, DTriP-22c, aurintricarboxylic acid, gliotoxin, amiloride
Proteins involved in replication & assembly Brefeldin A, geldenamycin, 17AAG
