It was discovered at the NIH and was licensed and initially developed by Isis Pharmaceuticals, which subsequently licensed it to Novartis.[2] It was licensed by the FDA for CMV in Aug 1998, and was the first antisense drug that was approved.[3]

Novartis withdrew the marketing authorization in the EU in 2002

HAART dramatically reduced the number of cases of CMV.[2]

antisense oligonucleotide -- a synthetic 21 member oligonucleotide with phosphorothioate linkages (which are resistant to degradation by nucleases
) and has the sequence:

  • 5'-GCG TTT GCT CTT CTT CTT GCG-3'

translation of viral mRNA by binding to the complementary sequence of the mRNA transcribed from the template segment of a key CMV gene UL123, which encodes the CMV protein IE2. It was the first antisense antiviral approved by the FDA.[7]
