Two items relevant to long COVID

One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater. A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more

Signature of success for an HIV vaccine?

Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009. Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful. The researchers think that this signature, Read more

Emory plays leading role in landmark HIV prevention study of injectable long-acting cabotegravir

Emory University played a key role in a landmark international study evaluating the safety and efficacy of the long-acting, injectable drug, cabotegravir (CAB LA), for HIV prevention.

The randomized, controlled, double-blind study found that cabotegravir was 69% more effective (95% CI 41%-84%) in preventing HIV acquisition in men who have sex with men (MSM) and transgender women who have sex with men when compared to the current standard of care, daily oral emtricitabine/tenofovir disoproxil fumarate 200 mg and 300 mg (FTC/TDF) tablets.

The study achieved its primary objective of non-inferiority with the difference approaching superiority in favor of cabotegravir, pending final analysis.

The findings were so positive that, during a planned review of study data, an independent Data and Safety Monitoring Board (DSMB) recommended the study results be announced as soon as possible. The study sponsor, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, agreed with that recommendation.

Emory, through the Emory-CDC HIV Clinical Trials Unit, enrolled 7% of the study’s more than 4,500 worldwide participants at three of its clinical research sites: The Hope Clinic (86 participants) and the Ponce de Leon Center (35 participants) in Atlanta and at the CDC’s Silom Community Clinic in Bangkok, Thailand (203 participants).

“This is a landmark study with a new approach that will change how HIV prevention is being done and will open the field to future interventions,” says Carlos del Rio, MD, the executive associate dean, Emory University School of Medicine at Grady Health System. Del Rio is a member of the study team and the principal investigator at the Ponce de Leon Center.

Four hot projects at Emory in 2017

Once activated by cancer immunotherapy drugs, T cells still need fuel (CD28)

— Rafi Ahmed’s lab at Emory Vaccine Center. Also see T cell revival predicts lung cancer outcomes. At Thursday’s Winship symposium on cancer immunotherapy, Rafi said the name of the game is now combinations, with an especially good one being PD-1 inhibitors plus IL2.

Pilot study shows direct amygdala stimulation can enhance human memory

— Cory Inman, Joe Manns, Jon Willie. Effects being optimized, see SFN abstract.

Immune responses of five returning travelers infected by Zika virus

— Lilin Lai, Mark Mulligan. Covered here, Emory Hope Clinic and Baylor have data from more patients.

Frog slime kills flu virus

— Joshy Jacob’s lab at Emory Vaccine Center. A follow-up peptide with a name referencing Star Wars is coming.
