Drug Makers Are Patient Advocacy Groups' Biggest Donors

Thai ALVAC-AIDSVax study published in NEJM this week.

From accompanying editorial (Raphael Dolin):
"The most important contribution of the study is most likely the opportunity to investigate possible host-response correlates of protection against infection. The establishment of such correlates is the central question in HIV vaccine development and will have a profound effect on the designs of vaccines andclinical trials to assess their efficacy.

Given the lack of detection of conventional immune responses in earlier studies of these vaccine components, as well as the divergence between the vaccine's effect on the infection and the effect on viral load, the correlates of protection may, indeed, reflect new concepts of host response. This should be the focus of intense research using the most current research techniques. Ultimately, it is the results of such studies that will most likely determine the significance of this clinical trial to the field of HIV vaccine development."

Kudos to Dr. Bob Siliciano and his Hopkins team for their persistence in pursuing this reservoirs issue

(Even if it is said that top retrovirologists view the eradication grail as unlikely ever to succeed)

Journal of Clinical Investigation (10/01/09)

From the Discussion section:

"Because of the high cost and potential toxicities of long-term HAART and the disappointing results from the clinical trials of HIV-1 vaccines and microbicides, there is still a pressing need for pursuing the goal of eradication.

To cure HIV-1 infection is exceptionally challenging and will likely require combining HAART with agents that can purge latent virus.

The identification of 5-hydroxynaphthalene-1,4-dione (5HN) not only expands the number of classes of latency-reversing agents but also demonstrates the possibility of utilizing pathway(s) further downstream of TCR stimulation to avoid global T cell activation.

Although the toxicities of 5HN raise concerns for its clinical application, this is a proof of concept for this approach to finding novel strategies to reactivate latent HIV-1 without inducing global T cell activation."
