Statement of Ltc. Deborah Birx
based on the wide variability of the viral burden assay (an observation with which Dr. Redfield agreed when Dr. Deborah Birx first raised it in the 15 SEP meeting) he reasserted his conclusion that the data suggest an antiviral effect of the vaccine." One of the conclusions of this meeting was, based on Dr. McCarthy's analysis relating viral burden to immunization, that viral burden data could be interpreted as safety of the rpgl60 vaccine; however, I do not recall any changes in procedures specifically delineated. At a subsequent NIH AVEG meeting on this same date, Dr. McCarthy stated that there was no relationship, other than random, between immunization and viral burden. "Overselling the gpl60 Phase I data may date back as early as the New England Journal of Medicine publication (N Engl J Med 1991:324:1677-84). Oral Presentations of the phase I continuation data over the last year and a half have repeatedly shown only a few selected "home run" patients. The data from the entire study group has not been well represented by these selected patients." Approximately half of the presentations regarding e ase I trials have been made by me and I have always presented the entire cohort. I did so at three national meetings in the past six months and there has never been any question of overselling or misleading information. Dr. Hendrix was not present at any of these meetings and he has not requested a copy of any of these presentations. We have presented all our data for scientific scrutiny at to other groups, including Dr. Fauci and his research staff. "Data analysis has been either sloppy or, possibly, deceptive with use of inappropriately chosen "control" groups, unorthodox statistical methods that abuses the data to come up with the desired CD4 trend conclusions..." This is a very serious allegation for which there is no basis. As a scientist who has participated in at least 90% of the parametric and non-parametric data analyses, I would not call t tests and the Wilcoxon test "unorthodox". It should be noted again that CD4 data have not been presented since the June 1991 NEJM article where the CD4 data were referenced only in terms of safety. It should be noted that at the Amsterdam meetings, the four papers which preceded Dr. Redfield's, reported either stabilization or increases in CD4 cell counts during the studies over 9 to 18 months of followup. "...failure to include appropriately performed analyses that fail to support the desired conclusion and badgering of statisticians and colleagues by Dr. Redfield, sometimes successfully, to agree to data analyses against their better 6
