Results from a recent large study confirm that Viread, which is also a component of Truvada and Atripla, causes kidney damage in people with HIV. The results also indicate that the kidney damage increases with each year of exposure and is irreversible.

Based on the results, the study authors recommended frequent kidney function monitoring for people who take Viread, Truvada, or Atripla. They also suggested that people who already have kidney problems may need to consider other antiretrovirals.

“Patients need to be aware of their kidney disease risks before they…

Results from a recent Japanese study indicate that a Viread-based antiretroviral therapy regimen causes greater loss of kidney function than a Ziagen-containing therapy, particularly in people with HIV who weigh less than about 130 pounds.

Based on the results, the study authors recommended that people with HIV who are taking Viread, Truvada, or Atripla (which both contain Viread) and have a low body weight be monitored for loss of kidney function at least twice per year, particularly during their first year of treatment.

The researchers also noted that further research…

Gilead Sciences announced yesterday that the U.S. Food and Drug Administration (FDA) has approved Viread for children two to 12 years of age, for use in combination with other antiretrovirals.

“We are very pleased to provide an important new therapeutic option for younger HIV patients, and will work to make the pediatric formulations of Viread available as quickly as possible,” said Norbert Bischofberger, executive vice president of Research and Development and chief scientific officer of Gilead Sciences, in a press release.

Viread will be available as tablets in smaller doses…

People With HIV Are At Increased Risk Of Six Cancers – Results from a recent study indicate that people with HIV are at an increased risk of developing Kaposi’s sarcoma, non-Hodgkin’s lymphoma, Hodgkin’s lymphoma, melanoma, anal cancer, and liver cancer compared to people without HIV. The researchers also found lung and oral cancers more frequently in people with HIV, but attributed this to lifestyle factors such as higher smoking rates. There was no increased risk of colorectal cancer and a reduced risk of prostate cancer. Results also showed that lower CD4 (white blood cell) counts were associated with an increased cancer risk. Higher viral load (amount of HIV in the blood) was only linked with a higher risk of Kaposi’s sarcoma and non-Hodgkin’s lymphoma. For more information, please see the press release from Kaiser Permanente or the study in Cancer Epidemiology, Biomarkers & Prevention (abstract).

Gilead Receives Approval For Eviplera In Europe – The European Medicines Agency (EMA) has approved Gilead Sciences’ new once-daily combination antiretroviral pill Eviplera (rilpivirine/emtricitabine/tenofovir) for the treatment of HIV in previously untreated adults with viral loads (amount of HIV in the blood) of 100,000 copies per milliliter or less. The approval means that Eviplera can be marketed in all 27 countries in the European Union. Eviplera, known as Complera in the U.S., was approved by the U.S. Food and Drug Administration in August. For more information, please see the Gilead Sciences press release.

AIDS Deaths Continue To Drop Worldwide – An annual report from the United Nations shows that the number of deaths worldwide due to AIDS has continued to drop for the third year in a row. The number of new HIV infections also fell 21 percent in 2010 compared to 1997; 70 percent of new infections were in sub-Saharan Africa. However, the number of people on antiretrovirals increased 20 percent in 2010 in sub-Saharan Africa, bringing the total to 50 percent of clinically eligible people with HIV in low- and middle-income countries. The report also notes that due to longer lifespans and greater survival rates, the number of people living with HIV now stands at an estimated 34 million, the highest ever. For more information, please see the United Nations report (pdf) or the article in the Washington Post.

Study Finds Viread Vaginal Gel Is Safe But Ineffective For HIV Prevention – Results from the Oral Interventions to Control the Epidemic (VOICE) study indicate that a vaginal gel containing 1 percent Viread (tenofovir) is safe but ineffective at preventing HIV infection in women. Based on the results, the National Institutes of Health, which is funding the study, has decided to drop the vaginal gel from the study. The trial, whose purpose is to provide women with methods to prevent HIV infection, will continue to evaluate the safety and efficacy of Truvada (emtricitabine/tenofovir) pills instead. The VOICE study was first modified in September after results showed that a Viread pill was also ineffective (see related AIDS Beacon news). For more information, please see the National Institutes of Health press release.

Congresswoman Lee Introduces Bill To Repeal Certain HIV Criminalization Laws – Representative Barbara Lee from California has introduced legislation that requires state officials nationwide to reevaluate HIV criminalization laws. The proposed legislation also offers incentives for states to repeal or modify laws that criminalize behavior by people with HIV that is legal for HIV-negative individuals or that has been shown scientifically to convey no measurable risk of HIV transmission. Representatives Hansen Clark and John Conyers from Michigan are co-sponsors of the bill. For more information, please see Rep. Lee’s press release or the article in the Michigan Messenger.

Large HIV Prevention Trial For Women Modified Due To Viread Inefficacy – A large trial that is testing the efficacy of Truvada (emtricitabine/tenofovir) pills, Viread (tenofovir) pills, and a Truvada vaginal gel in preventing HIV transmission to women has been modified because of interim results showing that Viread pills are ineffective. Based on the results, women in the Vaginal and Oral Interventions to Control the Epidemic (VOICE) study who were taking Viread will stop taking the drug and will no longer be included in the study. Women taking Truvada pills or the Truvada vaginal gel will continue as planned. For more information, please see the National Institutes of Health press release or the article on the Science Magazine website.

Phase 1 Clinical Trial Shows New HIV Vaccine May Be Highly Effective – Results from a Phase 1 clinical trial of a new preventative HIV vaccine in Spain show that 90 percent of healthy HIV-negative adults who received the vaccine showed an immune response; 85 percent still had an immune response one year after vaccination. This is a much higher percentage than researchers have observed in previous vaccine clinical trials. However, the scientists still have to show that the vaccine actually reduces the risk of contracting HIV. The researchers also plan to test the vaccine as a therapeutic vaccine in people who already have HIV to see if it reduces the severity of infection. For more information, please see the press release from Consejo Superior de Investigaciones Científicas or the articles on the ABC news and Fox news websites.

Clinical Trial To Test Victrelis In People With HIV And Hepatitis C Is Currently Recruiting Participants – A Phase 4 clinical trial that will test the efficacy of Victrelis (boceprevir) in HIV-positive adults with hepatitis C virus compared to HIV-negative adults with hepatitis C is currently recruiting participants. Study participants will receive Victrelis in combination with peginterferon-2b (PegIntron) and ribavirin (Rebetol). Eligible participants must not have taken the antiretrovirals Ziagen (abacavir), zidovudine (Retrovir), didanosine (Videx), stavudine (Zerit), Sustiva (efavirenz), or Intelence (etravirine) within the past six months. Additional medication and health restrictions also apply. For more information, please see the U.S. Clinical Trials Registry.
