 AB    Gene-expression modulator 91 (GEM91) is a 25-nt antisense
       oligodeoxynucleotide phosphorothioate complementary to the Gag mRNA of
       human immunodeficiency virus type 1 (HIV-1). Cellular uptake and
       intracellular distribution of GEM91 within cells suggest that this
       oligomer is readily available for antisense activity. GEM91 inhibited
       HIV-1 replication in a dose-dependent and sequence-specific manner. In a
       comparative study, 2 microM GEM91 was as effective as 5 microM
       3'-azido-3'-deoxythymidine in blocking virus replication during the
       28-day treatment of an HIV-1-infected T-cell line. GEM91 also completely
       inhibited (> 99%) the growth of three different HIV-1 isolates in
       primary lymphocytes and prevented the cytopathic effect of the virus in
       primary CD4+ T cells. Similarly, treatment with GEM91 for 3 weeks of
       HIV-1/BaL-infected primary macrophages blocked virus replication. Based
       on GEM91 anti-HIV-activity, safety, and pharmacokinetic profile in
       animals, a clinical trial was started using this compound as an
       antisense oligonucleotide drug for the treatment of the acquired
       immunodeficiency syndrome.
