OT: Biopure Says Hemopure Is Safe, but Holds On to Data
By Adam Feuerstein

Biopure (BPUR:Nasdaq - news - commentary - research) said Monday that a
statistical analysis of its human-blood substitute proves the experimental
product is safe, but the biotech company refused to release any data to
support its claim.

The company's announcement, in the form of a
press release, comes two weeks after
TheStreet.com uncovered mounting evidence
that Hemopure, its oxygen-carrying red blood
cell substitute, was unsafe and that Biopure
executives appear to be scrambling for ways to
portray the product in a more positive light.

On Monday, the company said that safety trials
for Hemopure met its primary endpoint, which
was to prove that "patients treated with
Hemopure have outcomes no worse than
patients treated with allogenic red blood cells per statistical methodology
previously agreed to by the [Food and Drug Administration]."

Commenting on the results, Biopure CEO Carl Rausch said, in a statement,
that "these results are a win for the company because they meet the study
endpoints previously agreed to by the Food and Drug Administration and are
supportive of our plan to file a marketing application later this year."

Shares of Biopure soared on the news, jumping $4.63, or 23%, to $24.53.

Today's announcement from Biopure does little to shed anything new on the
safety of the company's blood substitute. While releasing the apparent results
of a statistical analysis of Hemopure's safety, the company refused to release
any real data that would bolster its claims. This would include, most
significantly, the types and frequency of negative side effects.

The company also did not hold a telephone conference call with investors and
analysts to discuss results, as is the custom for biotech companies with
significant, market-moving news.

TheStreet.com has spoken to two doctors who have firsthand knowledge of
patients experiencing temporary kidney failure after being administered
Hemopure. TheStreet has also talked to other doctors who are aware of
additional cases of kidney failure and problems with elevated blood pressure,
after talking to doctors who treated these patients.

One of these doctors with first-hand knowledge of the product said today's
announcement from Biopure does not change his view that Hemopure is
unsafe and stands little chance of gaining FDA approval. He says the method
of statistical analysis used by Biopure easily obscures the significance of
major side effects with Hemopure, allowing the company to claim the product
met its statistical safety goals.

But when the FDA takes the covers off the study results and looks at
individual patients and their experiences using Hemopure, they will reach a
different conclusion, the doctor said.

Biopure executives would not return phone calls seeking comment, but in the
past they have steadfastly refused to acknowledge any side effects in
Hemopure patients. Today, CEO Rausch, speaking to Reuters news service,
acknowledged that some patients have suffered from temporary kidney failure
and elevated blood pressure.

"What we can say is that the incidence of these events was low in both
groups," Rausch told Reuters. "There is no statistical significance to these
events that we know of."

Biopure is basing its results on a study of 693 patients, half receiving
Hemopure and half receiving red blood cells. The study size, and the way it
was designed, was preapproved by the FDA, the company says.

But in recent weeks, it's become clear that U.S. drug regulators are taking a
harder look at blood substitutes. In the past two months, the FDA has ordered
Hemosol (HMSL:Nasdaq - news - commentary - research), a Biopure
competitor, to increase the number of patients in its blood substitute test from
700 patients to 900 patients in order to better gauge the product's safety.
More recently, the FDA asked Hemosol to make even more changes to the
design of its tests, which has forced the company to significantly delay
development.

And just because a trial design was preapproved doesn't mean Biopure or any
other company is in the clear with the FDA. In July, the FDA rejected an
experimental asthma drug from Genentech and Novartis on safety concerns,
even though the companies and regulators had previously agreed on a safety
threshold. In essence, the FDA changed its mind and didn't tell the
companies.

So Monday, Biopure tried to put the question of Hemopure's safety to rest.
Instead, the company's announcement just raises more questions. The firm
said further data would be made public at "appropriate medical forums," but
as of two weeks ago, the company was not scheduled to appear at any
medical or scientific conferences this fall. Biopure is scheduled to give a
presentation at one investment banking conference in October.

With the company's reluctance to provide concrete proof of Hemopure's
safety, the issue may not be resolved until the FDA conducts its own
examination. If Biopure submits an approval application for submission later
this year, investors may have to wait until well into next year before all the
questions are answered.

no mention of secondary endpoints

I've never ever seen any mention of the secondary endpoints. Anyone know what they are?
