The development of AZT and other NRTIs showed that treating HIV was possible, and these drugs paved the way for discovery and development of new generations of antiretroviral drugs.
What has NCI done to help develop new HIV drugs?
As researchers learned more about HIV in the following years, they were able to develop drugs that attacked the virus in new ways. 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.

The discoveries of NCI researchers in the early days of HIV/AIDS were vital in transforming HIV infection from a fatal diagnosis to the manageable condition it is for many today. Patients with the mysterious immune disorder now known as AIDS had been arriving at the NIH Clinical Center since 1981.
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. When combined with reverse transcriptase inhibitors, protease inhibitors, developed in the mid-1990s, dramatically suppressed replication of the virus, often reducing it to undetectable levels.

In a randomized trial, it was subsequently ...
Is AZT effective for AIDS?
Because AZT was not entirely effective by itself, NCI scientists continued to develop and test other drugs to treat AIDS, including the reverse transcriptase inhibitors didanosine (ddI) and zalcitabine (ddC). These became the second and third drugs approved by the FDA for AIDS. Combining AZT with one of these drugs improved the effectiveness ...

When did monotherapy start?
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 new class of anti-HIV drugs?
After 1991, several other nucleoside analogs were added to the anti-HIV arsenal, as were a new class of anti-HIV drugs called the non-nucleoside analog reverse transcriptase inhibitors which work in similar ways to the nucleoside analogs but which are more quickly activated once inside the bloodstream.
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.
Why is combination therapy important?
By using more than one drug at a time, combination therapy is able to "pin down" HIV from more than one angle, so that even if one drug fails, another can continue to suppress viral replication.

The New York Times was the first newspaper to report a new syndrome, seen in the homosexual communities of San Francisco and New York, on 3rd July 1981. Previously healthy men, some only in their 20s were suffering from rare diseases usually only seen in the elderly, such as the rare cancer: Kaposi’s sarcoma.
The identification of a virus
In January 1984 research was published which linked a number of cases of AIDS, and suggested that the disease was sexually transmitted.
The search for a treament
Once it was known that AIDS was caused by a human retrovirus, the search for drug-treatments began. The viral enzyme reverse transcriptase, is used by retroviruses use to construct DNA from their viral RNA once they have infected a cell. Humans and other mammals do not make this enzyme, making it an obvious drug target.

Those who will develop this disease may take some comfort in knowing that today’s hepatitis C treatments differ extremely from what was available when it was first discovered in 1989.
What drugs were used to treat hepatitis C?
The results were two protease inhibitors (PIs) called boceprevir (Victrelis) and telaprevir (Incivek). With precision, these drugs directly targeted hepatitis C and worked to stop the virus from spreading.
What antiviral pill is used for hepatitis C?
In 2014 and 2015, hepatitis C genotype-specific drugs were created that could target particular types of hepatitis C. These included: Sofosbuvir/ledipasvir (Harvoni). This antiviral pill fights hepatitis C genotypes 1 and 3 at different stages during its life cycle by blocking proteins that cause the virus.

When was azidothymidine first used?
Scientists funded by NIH’s National Cancer Institute (NCI) first developed azidothymidine (AZT) in 1964 as a potential cancer therapy. AZT proved ineffective against cancer and was shelved, but in the 1980s, it was included in an NCI screening program to identify drugs to treat HIV/AIDS. In the laboratory, AZT suppressed HIV replication without damaging normal cells, and the British pharmaceutical company Burroughs Wellcome funded a clinical trial to evaluate the drug in people with AIDS. Used alone, AZT decreased deaths and opportunistic infections, albeit with serious adverse effects. In March 1987, AZT became the first drug to gain approval from the U.S. Food and Drug Administration for treating AIDS. AZT, also referred to as zidovudine, belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors, or NRTIs.

What was the name of the new class of antiretroviral drugs?
The mid-1990s marked the emergence of another new class of antiretroviral drugs called non-nucleoside reverse transcriptase inhibitors or NNRTIs. Because they are cheaper and easier to produce than protease inhibitors, they helped scale up antiretroviral therapy in resource-limited settings.
What is the primary co-receptor used by HIV?
A number of research groups, including NIAID scientists, determined that a different receptor called CCR5 is actually the primary co-receptor used by HIV to infect immune cells. This work laid the foundation for the development of the CCR5- blocking drug maraviroc, which received FDA approval in 2007.
When did saquinavir get FDA approval?
In December 1995, saquinavir became the first protease inhibitor to receive FDA approval. In 1996, results from an NIAID-sponsored trial showed that a three-drug regimen of saquinavir, ddC, and AZT was more effective than two-drug therapy with ddC and AZT. One of the key studies demonstrating the efficacy of triple-drug therapy was ACTG 320, ...

Still Not A Cure
- In all, the simultaneous treatment of people with HIV with different classes of antiviral drugs is among the most significant scientific advances in the history of the AIDS epidemic. Five years after its widespread use, combination antiviral therapy has demonstrated enormous potential, eliminating early fears that it would prove to be yet another dead-end in the treatment of HIV infe…
The Post-Vancouver State of Combination Treatment
- Overall, for people living with HIV disease, as well as professionals working with them, the news about the effectiveness of combination therapies that emerged in 1996, particularly from that year's International AIDS conference in Vancouver, was heartening but also confusing. During and after the conference, mainstream media reporting made it seem as if a total cure had been disc…
