afovirsen

Afovirsen is an **antisense oligonucleotide** that was investigated as an antiviral agent, specifically as a phosphorothioate oligonucleotide. It is designed to bind complementary viral messenger RNA (mRNA) sequences, thereby inhibiting their translation and ultimately viral replication. While detailed clinical results for afovirsen are not broadly available, the compound was studied as a synthetic antisense agent, similar in concept to fomivirsen, but its specific clinical indications, approval status, and manufacturers are not widely documented in the medical literature. The most closely related compound with clinical data, fomivirsen, was used to treat cytomegalovirus retinitis in patients with AIDS by targeting the immediate early region 2 of CMV mRNA[10][8][4].
