The undersigned organizations strongly support the D:A:D study.

HIV drugs are used in combinations, so it is right that the companies who make and sell these drugs collaborate on this study on long-term safety.

We urge the following companies to continue funding this vital study: AbbVie, Bristol-Myers Squibb, Gilead Sciences, Janssen, Merck Sharpe Dohme and ViiV Healthcare.

The funding must also make it possible to add new patients to the D:A:D database for another five years, since many will be starting treatment with newer HIV drugs.

For over 15 years the D:A:D study has been a remarkable collaboration.

Since 1999, it has included:

  • The US and European drug safety bodies (the FDA and the EMA)
  • Drug companies that manufacture HIV drugs
  • Independent scientists and researchers
  • HIV community representatives

What has the D:A:D study shown so far?

D:A:D was originally set up to look at HIV drugs and the risk for liver and heart disease.

Since then, D:A:D  has answered many other long-term safety issues.

These include:

  • The risk of rare side effects from individual drugs
  • HIV drugs and body shape changes
  • HIV drugs and blood pressure
  • The long-term safety of HIV drugs and the liver
  • HIV and hepatitis coinfection
  • A new HIV-specific calculator for heart disease risk
  • Causes of, and risk for, death among HIV-positive people
  • Making sure that causes of HIV-related deaths are recorded accurately
  • HIV drugs and kidney disease
  • HIV and cancers, especially non-AIDS cancers
  • HIV drugs and diabetes
  • HIV drugs and stroke

D:A:D combines results from over 50,000 HIV-positive people from 11 research networks in Australia, Europe and the US.

Although the companies no longer have to fund this study, we think D:A:D is too important to let close.

Results from D:A:D have been used to change HIV treatment guidelines and the way people are treated by their health care providers.

D:A:D has developed practical tools for estimating risk of heart and kidney disease in HIV-positive people.

D:A:D has also reported new side effects that were not found when the drugs were first studied, including:

  • Heart disease with abacavir, ddI, saquinavir, lopinavir/ritonavir, and indinavir/ritonavir
  • The risk for diabetes with d4T
  • Kidney damage with tenofovir, atazanavir/ritonavir, and lopinavir/ritonavir

D:A:D has also showed that other drugs did not have these side effects.

D:A:D has also shown whether guidelines are being followed.

  • It reported on use of lipid lowering drugs among HIV-positive people
  • It provided evidence that stopping smoking has similar impact on heath for HIV positive people as the general population
  • It showed that people at high risk of suicide were not using efavirenz (and that efavirenz did not increase suicide rates in people who were not at high risk)

What is needed now?

We need this essential study to continue.

We need new patients to be included to answer the same questions for the newest drugs and combinations.

Why do we need D:A:D to continue?

D:A:D is critical for many reasons:

  • D:A:D results gives people the confidence to start HIV treatment. It is an independent study that produces real-life data (including people who are not well-represented in studies, including women).
  • Because HIV treatment is now being used earlier and at higher CD4 counts.
  • Because D:A:D can detect new safety concerns that we might not yet know about.
  • D:A:D can look at risks in specific groups of people living with HIV. For example, by age at infection, gender, ethnicity, race, sexual orientation, illicit drug use, and in younger and older people.
  • ART is lifelong. We therefore need longer-term information about drug- and drug class-specific safety and tolerability, including additional data on reversibility of toxicities when drugs are switched.
  • D:A:D can identify safety concerns or rule out concerns with new drugs or drug classes. This includes the newest integrase inhibitors (raltegravir, elvitegravir, dolutegravir). It can look at new drugs like etravirine, cobicistat and the new version of tenofovir (TAF).
  • D:A:D can look at long-term outcomes after treatment with new hepatitis C drugs. More than 4,000 people in D:A:D are infected with both HIV and hepatitis C.
  • We need to know more about generics and co-formulated drugs.
  • We need to know more about drug-drug interactions and long-term safety. This is particularly true as we get older. By 2016, more than 5,000 people in D:A:D will be over 60. Half of the people in D:A:D will have been using HIV meds for more than 10 years.

If D:A:D is allowed to end, it will be lost forever.

If there is a new safety issue, we will not be able to rebuild D:A:D—16 years of results will be lost.

For these reasons, we urge the above companies to support the D:A:D study for another five years.

Continuing to fund D:A:D makes a powerful statement about your company’s commitment to people living with HIV/AIDS.

Your support sends a clear message about supporting our communities and health care providers.

This research is invaluable to millions of people living with HIV/AIDS. It has a direct effect on our lives.

We hope to hear that you are willing to continue supporting D:A:D.
