FDA Accepts Zonagen's Impotence Drug Vasomax For Review

Dow Jones Online News, Thursday, September 24, 1998 at 16:03

By Melanie Trottman, Staff Reporter
NEW YORK -(Dow Jones)- A potential new contender in the market to
treat male erectile dsyfunction has passed another milestone.
Zonagen Inc. (ZONA) said Thursday that the Food and Drug
Administration agreed to review the company's new drug application for
Vasomax, a pill to treat the condition that would compete with Pfizer
Inc.'s blockbuster drug Viagra.
The FDA's filing acceptance generated a $5 million milestone payment
for Zonagen from Schering-Plough Corp. (SGP). Vasomax was licensed to
Schering-Plough in November under conditions that the Madison, N.J.,
maker of health-care products would pay Zonagen $10 million up front and
make subsequent milestone payments as specific regulatory goals were
achieved. If Zonagen meets all the goals, the up-front and milestone
payments will total $57.5 million; that doesn't include royalties.
A Zonagen spokeswoman declined to comment directly on the stock
increase but said, "I presume people assume it's a positive event for
us."
The company presented results from its late-stage, or Phase III,
trials of Vasomax at the American Urology Association meeting in early
June. As reported in The Wall Street Journal, results showed that 37% to
45% of about 300 patients taking Vasomax achieved better erections than
without the drug. Pfizer Inc.'s (PFE) Viagra helps about 70% of impotent
men.
Industry analysts who follow the company said safety data from the
Vasomax trials were good, but indicated Viagra is seen as more potent.
They don't expect Vasomax, if approved, to reach the blockbuster status
that Viagra has attained.
"It's slightly less effective and it comes second" to market, said
Mehta Partners analyst Sergio Traversa, adding that he is neutral on the
company.
Analysts estimate Vasomax would seize a market share equal to about
25% of Viagra's. Part of that is seen coming from an expansion of the
impotence market, while another portion is expected to come from
patients who have had no success using Viagra. They would likely be the
first to try Vasomax, analysts said.
Other companies working to get products for erectile dsyfunction to
market include MacroChem Corp. (MCHM), which recently said interim-stage
clinical trials supported the effectiveness and safety of its Topiglan
gel.
Also, TAP Holdings Inc., a joint venture of Abbott Laboratories (ABT)
and Takeda Chemical Industries Ltd. of Japan, is developing apomorphine,
which acts directly on the brain to create erections.
Researchers have cautioned that none of the drugs has been directly
compared with Viagra in scientific studies, so definitive conclusions
can't be drawn.

By the end of the day, ZONA was up only 3/4 on this news. I'm not knocking the $5 million milestone payment but milestone payments aren't what will make ZONA worth this stock price. I believe the stock price will erode from now till FDA's decision, as I outlined before.

The estimate of 25% of Viagra sales in the news item Craig posted, is pure wishful thinking. With such a lower success rate and being tried only on people who failed with Viagra, it would be amazing if Vasomax obtained 2% of Viagra's sales.

What tests were done on people who fail with Viagra to see how many of them are helped by Vasomax? Viagra is supposed to help a wider population than Vasomax, in helping mild to moderate cases of ED. Vasomax, if it helps anyone (dubious that it does), only mild cases. So those that fail with Viagra are in my opinion likely to be the moderate to severe cases, leaving almost nothing of Vasomax' mild population unhelped by Viagra. So, Vasomax may help almost no one who wasn't helped by Viagra (assuming it works at all, which is questionable).

That 25% figure is pure hype but that will be shown only if the drug is approved, I guess, so we won't have the proof of the accuracy of what I'm saying for two years, if ever.
