What is an investigational drug?
An investigational drug is one that is under study and is not approved by the U.S. Food and Drug Administration (FDA) for sale in the United States. Medical research studies are conducted to evaluate the safety and effectiveness of an investigational drug. These research studies are also called clinical trials. Once an investigational drug has been proven safe and effective in clinical trials, FDA may approve the drug for sale in the United States.
What is BMS-986001?
BMS-986001 is an investigational drug that is being studied for the treatment of HIV infection.
BMS-986001 belongs to a class (group) of HIV drugs called nucleoside reverse transcriptase inhibitors (NRTIs).2
NRTIs block an HIV enzyme called reverse transcriptase. (An enzyme is a protein that starts or increases the speed of a chemical reaction.) By blocking reverse transcriptase, NRTIs prevent HIV from multiplying and can reduce the amount of HIV in the body.
BMS-986001 is similar in chemical structure to the FDA-approved NRTI stavudine (brand name: Zerit). However, in vitro
studies have shown that BMS-986001 may be more effective than stavudine and may be less toxic than stavudine and other NRTIs. 4,5,6
studies are studies done in test tubes or other laboratory equipment and not on animals or humans.) Research in animals has shown that BMS-986001 is not associated with kidney or bone toxicities.7
How are clinical trials of investigational drugs conducted?
Clinical trials are conducted in phases. Each phase has a different purpose and helps researchers answer different questions.8
- Phase I trials: Researchers test an investigational drug in a small group of people (20–80) for the first time. The purpose is to evaluate its safety and identify side effects.
- Phase II trials: The investigational drug is administered to a larger group of people (100–300) to determine its effectiveness and to further evaluate its safety.
- Phase III trials: The investigational drug is administered to large groups of people (1,000–3,000) to confirm its effectiveness, monitor side effects, compare it with standard or equivalent treatments, and collect information that will allow the investigational drug to be used safely.8
In most cases, an investigational drug must be proven safe and effective in a Phase III clinical trial to be considered for approval by the FDA for sale in the United States. Some drugs go through the FDA’s accelerated approval process and are approved before a Phase III clinical trial is complete. After a drug is approved by the FDA and made available to the public, researchers track its safety in Phase IV trials to seek more information about the drug’s risks, benefits, and optimal use.8
In what phase of testing is BMS-986001?
BMS-986001 is currently being studied in a Phase IIb clinical trial.2
What have recent studies shown about BMS-986001?
In a 10-day Phase Ib-IIa study, four different strengths of BMS-986001 taken once daily were compared with placebo in HIV-infected participants who had taken HIV medicines before entering the study (treatment-experienced) but who were off HIV medicines for at least 3 months. (A placebo is an inactive drug that is identical in appearance to the active drug being studied.) Study participants did not receive additional HIV medicines as part of a background regimen. (A background regimen is a combination of drugs that are not being studied as the investigational drug[s] in the clinical trial, but are being given to help control a participant’s HIV infection.)9,10
In this study, significant reductions in the amount of HIV in the blood (viral load) were seen after 10 days of treatment with each of the BMS-986001 doses studied. In terms of safety, BMS-986001 was generally well tolerated.9,10
A Phase IIb study of BMS-986001 is under way in HIV-infected adults who had never taken HIV medicines before entering the study (treatment-naive).11
What side effects might BMS-986001 cause?
In the 10-day Phase Ib-IIa study discussed under the previous question, side effects were reported by participants but no clear pattern of side effects was seen.9
Because BMS-986001 is still being studied, information on possible side effects of the drug is not complete. As testing of BMS-986001 continues, additional information on possible side effects will be gathered.

I am interested in participating in a clinical trial of BMS-986001. How can I find more information about participating in a clinical trial?
Participating in a clinical trial can provide benefits. For example, a volunteer participant can benefit from new research treatments before they are widely available. Participants also receive regular and careful medical attention from a research team that includes doctors and other health professionals. However, clinical trials may also involve risks of varying degrees, such as unpleasant, serious, or even life-threatening side effects from the treatment being studied.8
