VaxGen's
AidsVax: paper urges "watch the tycoon and
tout" as results row deepens
The failure of
AidsVax to prevent infection with HIV - in
clinical trial results published in 2003 -
triggered an intense debate about the
controversial product and its manufacturer,
VaxGen Inc of Brisbane, California. Mail to this
website, maintained by Brian Deer, shows that existing material on a
VaxGen-AidsVax index is read by significant
numbers. This page seeks to further inform the
discussion
In a news report published on
Friday February 28 2003 by the San Jose
Mercury-News - a near neighbour of the South San
Francisco-based VaxGen - the company's
start-of-week position seemed to be crumbling.
Under straplines "Biotech trouble" and
"VaxGen stands by its vaccine", the
paper's business section reported:
STOCK PRICE FALLS ON NEW
QUESTIONS OVER DISAPPOINTING VACCINE RESULTS
Under the
by-line Paul Jacobs, the story opens:
VaxGen executives stood firm Thursday under
mounting criticism from scientists who
questioned the way the biotech company
analyzed its results finding its AIDS vaccine
may protect blacks and Asians more than
others.
Jacobs
reports that one "academic consultant"
to the company, "while not ruling out"
that there may be racial and ethnic differences
in response to the vaccine, as VaxGen had
claimed, said "it should have corrected its
findings." He said that a corrected analysis
suggested that any protective effect in minority
volunteers could be much smaller than VaxGen had
claimed and was possibly non-existent.
``It could be a real effect, or it could be a
fluke,'' said Steven G. Self, a
biostatistician of the Fred Hutchinson Cancer
Research Center and University of Washington
in Seattle. ``It's interesting enough to look
at and find out which it is.''
But he said it was ``premature'' for the
company to take the results to the Food and
Drug Administration in an effort to license
the vaccine for use by specific ethnic or
racial groups.
The Brisbane company, responding to
criticisms published in Science magazine and
elsewhere, stood by its statistics Thursday:
``The results VaxGen reported on Monday
remain accurate as stated, and the analysis
continues.''
Earlier this week, VaxGen announced that the
first large test of its AIDSVAX vaccine in
more than 5,000 volunteers, mostly gay men,
showed that the vaccine failed overall to
offer protection against the human
immunodeficiency virus or HIV, which causes
AIDS. Altogether, 5.7 percent of those who
received the vaccine became infected over the
course of three years compared to 5.8 percent
of those who got dummy shots, or placebos.
The difference was not statistically
significant.
But the company reported that the vaccine
showed a significant reduction in infections
among certain vaccinated groups -- a 67
percent lower rate among non-Hispanic
minorities, and 78 percent lower among
blacks.
Four AIDS advocacy groups issued a statement
accusing the company of playing ``the numbers
game'' to serve ``the commercial interests of
the company.'' Central to their argument are
the small numbers of non-Hispanic minorities
in the study -- just 498 -- and the even
smaller number of HIV infections, just 13
among 314 black participants and four among
Asians.
Self and other statisticians say that the
small numbers limit what they call the
``power,'' or the reliability, of the
findings.Among the blacks who were infected
were four women, who all received placebos
and not the vaccine -- from a Chicago test
site.
That raises the possibility that at least
some of the apparent effectiveness of the
vaccine in minorities is the result of gender
and not race, says Neil J. Risch, a professor
of genetics at Stanford University.``My
opinion is they did not study enough
African-Americans,'' he said. The results
don't prove that there was an effect, he
said, but they do suggest the need for
further stud.
The
Mercury-News concludes its news report, published
four days after VaxGen released what it said were
initial results of the AidsVax trial, by noting
that the company's stock had continued to dive,
closing at $4.25, down 12 percent for the day and
67 percent for the week.
Menwhile,
the Mercury-News continued its coverage on the
same day with a column by Scott Herhold, who
encapsulated recent events surrounding VaxGen -
including the hyping of its stock by
"investment analyst" Porter Stansbury, cited at this
website. Under the headline "Firm's players
show self-interest can taint views", Herhold
points out that behind every major stock market
drama there are dozens of cameos:
In that spirit, let me introduce you to an
intriguing sidebar to the meltdown early this
week of VaxGen, the Brisbane company that
lost more than half its value when its AIDS
vaccine fell short. It's the story of the
tycoon and the tout.
He tells his readers that they
know the background, before filling them in on
what they may not have followed as closely as
Herhold himself clearly has:
What you may not know is how intimately the
tycoon -- Microsoft co-founder Paul Allen --
was involved with the company, or what his
departure from the stock in recent months
signaled.And unless you're a VXGN investor,
you probably don't know how vigorously a
newsletter writer named Porter Stansberry
pushed the stock. Even as the results came
in, he stayed positive, saying, ``I have remarkable
news.''
The opposing directions taken by these two
men can teach investors a fundamental lesson:
Self-interest bends our point of view.Take
the tycoon first. Through his investment arm,
Vulcan Ventures,
Paul Allen was an early investor in VaxGen,
which spun off from the better-known
Genentech in the early '90s. In December,
1999, after VXGN had already gone public,
Allen stepped up his investment in a big way,
putting $25 million into the company to fund
its AIDS research. At $11.50 a share, he
bought nearly 2.2 million shares. By
mid-2000, he owned more than 20 percent of
the company. A Vulcan Ventures biotech
analyst, Ruth Kunath, took a board seat.
But over the past year, Allen has edged away
almost completely from VaxGen. Kunath quit
the board in mid-2002. And by the end of
2002, Allen had only 664,682 shares left,
shares he filed to sell by the end of
January. (While SEC records don't indicate
those sales were completed, you can assume
they were.)
Newsletter writer Stansberry, meanwhile, was
headed in the opposite direction. On his
site, Pirateinvestor.com, he's been bullish
on VaxGen for at least two years. In January,
about the time Allen was bailing, he sent out
a note urging investors to buy
his newletter (special price: $74.50)
detailing his research on the AIDS vaccine.
Although he didn't mention VaxGen by name, it
was clear Stansberry was describing the
company when he said, ``I've uncovered a
business currently worth $250 million that
will soon be worth several billions. . . . In
a matter of weeks, this stock will skyrocket
when a story about it appears in the Wall
Street Journal.''
In fact, much the opposite happened. But even
as VaxGen was announcing its disappointing
results Sunday night, Stansberry refused to
surrender. Noting seemingly hopeful numbers
among Asians and blacks, he concluded,
``AIDSVAX seems to work.''
So whom to follow, the tycoon or the tout? At
a glance, you'd say Allen in a heartbeat. And
you'd be right, though the record is mixed.
Over time, Stansberry has picked a number of
winners. And Allen has taken some notorious
losses, particularly in cable and fiber
optics.
What makes the choice clear, however, is the
context. Remember that the purpose of Allen's
investment was to further the company's AIDS
vaccine research. Remember, too, that he has
a biotech analyst who sold her own shares.
When Allen leaves, it matters. (Neither
Vulcan nor Stansberry responded to requests
for comment.)
The newsletter writer, meanwhile, bought into
the stock himself recently, though he says
the purchases came after his newsletter
appeared. So it's safe to assume he had a
vested interest in keeping VaxGen afloat even
after the flood started.
Given the company's slender prospects, it's
an ever grimmer task. Since Sunday, further
questions have come up about VaxGen's claim
of good results among some minorities. The
stock finished Thursday at $4.25, down 79
percent from its January high of $19.94.
