Despite this proliferation of drug options, the standard antiviral therapy for HIV-infected individuals between 1986 and 1995 for the most part remained "monotherapy" or treatment with a single drug. Such drugs appeared to be partly efficacious, although there was a great variation in effectiveness among individuals.
What is the class of antiviral drugs that prevents HIV infection?
Next to be developed were the class of antiviral drugs known as protease inhibitors, which were distinctly different from the reverse transcriptase inhibitors in that they do not seek to prevent infection of a host cell, but rather to prevent an already infected cell from producing more copies of HIV.

When was AZT approved?
In a randomized trial, it was subsequently shown to improve survival of AIDS patients. In 1987, it became the first drug approved by the U.S. FDA for treatment of the disease. AZT was subsequently shown to markedly reduce the perinatal transmission of HIV.
What enzymes did the NCI develop?
NCI’s strong industry collaborations helped speed patient access to the new drugs. The NCI researchers first focused on a viral enzyme called reverse transcriptase that HIV needs to multiply. They developed an assay to test the utility of drugs against HIV and gathered a number of promising compounds to test.
What enzymes were used to map out the structure of HIV?
NCI scientists helped map out the structure of another essential viral enzyme, the HIV protease, to guide the design of a new class of HIV drugs.

In a randomized trial, it was subsequently ...
