AZT belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors ( NRTIs ). Scientists funded by the NCI developed azidothymidine in 1964 as a potential treatment for cancer and while the drug showed promise at stopping tumor cells from replicating, the drug was deemed largely ineffective and shelved for decades.
A Fast-Track Approval Rife with Controversy
The 1987 research, which was published in the New England Journal of Medicine, ultimately led to the approval of AZT. This double-blind, placebo-controlled study aimed to test the efficacy of AZT in 282 patients diagnosed with AIDS or AIDS-related complex. Of them, 145 people were given AZT and 137 the placebo for a total of 24 weeks.

When did NRTI drugs get FDA approval?
In the early 1990s, additional NRTI drugs gained FDA approval. 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 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.

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, ...
What is AZT treatment?

What is reverse transcription?
Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell (where it is called a provirus ). Cellular enzymes convert AZT into the effective 5'-triphosphate form.

AZT: The First Drug to Treat HIV Infection
- 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 dam...
Accelerating Antiretroviral Drug Development
- Established in the early years of the HIV/AIDS pandemic, the NIAID-supported National Cooperative Drug Discovery Group Program for the Treatment of AIDS (NCDDG-AIDS) provided a framework for scientists from academia, industry, and government to collaborate on research related to the identification and development of new drugs. NIAID-supported researchers develo…
The Advent of Combination Therapy
- The limitations of single-drug treatment regimens quickly became apparent. HIV replicates swiftly and is prone to errors each time it does. These errors, or mutations, cause small changes in the virus. HIV variants with mutations that confer resistance to an antiretroviral drug can evolve rapidly. In some people taking AZT alone, drug resistance developed in a matter of days. Scienti…
Durable HIV Suppression with Triple-Drug Therapy
- While the effects of two-NRTI therapy were better than those of single-drug therapy for many people with HIV, they were of limited duration. A major advance came in 1996, when researchers found that triple-drug therapy could durably suppress HIV replication to minimal levels, while creating a high genetic barrier against development of drug resistance. The possibility and succ…
Identifying New Classes of Antiretroviral Drugs
- To address the complexity of antiretroviral regimens, drug toxicities, and the issue of drug resistance, NIAID supports research aimed at novel formulations and development of drugs that work by different mechanisms and target various steps in the HIV replication process. Currently, more than 30 antiretroviral drugs are available, including several fixed-dose combinations, whic…
