Technology evaluation: StealthVector (HIV) Enzo.
Efficient inhibition of human immunodeficiency virus-1 (HIV-1) replication with intracellularly expressed antiviral genes would be an important step toward clinical gene therapy for HIV-1 disease. Enzo Biochem is investigating and developing antisense genes as a potential gene therapy approach against a variety of conditions including acquired immunodeficiency syndrome (AIDS), cancer and hepatitis. The subsidiary of Enzo Biochem, Enzo Therapeutics, utilized its StealthVector technology and initiated phase I trials in July 1998 [291511,307156]. StealthVector, which is comprised of independent antisense sequences directed against two functional HIV-1 regions, is involved in regulation of gene expression soon after HIV infection, transactivation response (TAR) and tat/rev. StealthVector localizes primarily in the cell nucleus, where it could be most effective in inhibiting viral growth.
