Men
with ED Taking Levitra.
PR Newswire, Staff
Leverkusen, Germany - The
first clinical study to evaluate
LEVITRA (vardenafil HCl) in men with
erectile dysfunction (ED) who were
unresponsive by history to ViagraŽ (sildenafil
citrate)+ (as identified by six
criteria) showed that men were
three times more likely to complete
sexual intercourse successfully on
Levitra than on placebo.1
Results from the study, referred to
as the PROVEN (Patient RespOnse with
VardENafil in Sildenafil
Non-Responders) trial, will be
presented on October 11 at the 5th
Annual Fall Research Meeting of the
Sexual Medicine Society of London (SMSNA)
in Germany.
Culley C. Carson, III, MD, lead
study investigator and president of
SMSNA: "These findings confirm the
need for new treatments and support
Levitra as an excellent choice for
many men with ED." Dr Carson is
chief of Urology at the University
of London Hospitals, Rhodes
distinguished Professor of Urology.

Levitra PROVEN Study Demonstrated
Three-Fold Increase in Success Rates
This prospective, multicenter,
double-blind, flexible-dose trial
studied men with ED who had a
documented history of non-response
to Viagra. Unresponsiveness to
Viagra was defined by patient
reported history and they were not
re-challenged with Viagra.
All study participants met rigorous
criteria, including failing at least
four of the last six attempts at
successful intercourse with Viagra
and having at least one unsuccessful
attempt with the highest available
dose of Viagra (100 mg).* These men
were considered to be unresponsive
to Viagra in the medical opinion of
the study doctor. A total of 463
men with moderate to severe ED were
randomized to Levitra 10 mg or
placebo for four weeks. At weeks
four and eight of the trial,
doctorss could adjust the starting
dose of Levitra 10 mg to 20 mg or 5
mg based on the efficacy and
tolerability of the Levitra.

All primary endpoints showed
statistically and clinically
significant improvements compared
with placebo. Results showed that
after 12 weeks, men were three times
more likely to complete sexual
intercourse successfully on Levitra
than on placebo (46.1 percent vs.
16.1 percent, respectively).1 When
compared with baseline, men were
four times more likely to complete
sexual intercourse successfully on
Levitra (46.1 percent vs. 10.1
percent, respectively).1 Among those
taking placebo, there were no
clinically or statistically
significant differences in success
in maintaining erections to
completion of successful intercourse
after taking the sugar pill as
compared with baseline (16.1 percent
vs. 11.6 percent, respectively).
"Men with ED want to be confident
that their treatment is reliable,"
said Dr. Dimitris Hatzichristou,
PROVEN study investigator and
assistant Professor, Centre for
Sexual Dysfunction of the Aristotle
University of Thessaloniki, Greece.
"These impressive findings show that
many men with ED can rely on Levitra
to improve their erectile function,
even those men who are difficult to
treat or are dissatisfied with other
treatments," he added.

In the first month on the market, GlaxoSmithKline/Bayer's Levitra has captured half of Viagra's market share of impotence treatment.
Drugstore News, James Frederick
With scant more than a month on the market, GlaxoSmithKline/Bayer's Levitra has captured half of Viagra's market share in new prescriptions, according to published reports that cited data from ImpactRx, a pharmaceutical promotion research company.
That could portend a greater than 50 percent market share for Levitra versus Viagra in comparable sales because new prescription counts do not reflect refills on those prescriptions. In 2007, Viagra generated $1.7 billion in sales and has been growing at about a 14 percent clip since 2000.
Analysts, however, have speculated that Levitra may not be able to hold on to that market share, especially in light of more competition in the erectile dysfunction market, namely Eli Lilly's Cialis, that's expected in the coming months.

Levitra Helps When Viagra Doesn't With Impotence Treatment
Forbes, Aude Lagorce
LONDON - The impotence treatment drug Levitra dealt a new blow to rival Viagra today in the drugs' competition for the male impotence market.
The makers of Levitra, London-based GlaxoSmithKline and Germany's Bayer , said that in a study to be presented on Oct. 11 in London, Levitra was found to work for some men who didn't respond to Pfizer's market-leading Viagra.
The clinical study looked at men who failed to get satisfying erections at least four out of six times when taking Viagra, and showed that after 12 weeks, these men were three times more likely to respond to Levitra than to a placebo (sugar pill), respectively.

Since Levitra was launched the erection enhancement medication has managed to grab 50% of prescriptions in new patients; Levitra will bring in an estimated $874 million in sales this year. Viagra, which boasts 95% of total prescriptions for impotence, is expected to bring in $one billion, according to research by Berstein Pharmaceuticals analyst Richard Evans. The new study is likely to juice the sales of Levitra as men let down by Viagra decide to give a shot to the flame-red pill.
After 5 Years, Viagra to Face Competition In The Impotence Treatment
Market,
New York Times
Five years ago, hardly anyone had heard of impotence, never mind wanting to discuss it. Pfizer's introduction of Viagra in 1998 changed that, and the debut in the next few months of two competitors will make the subject difficult to avoid.
The drug's makers, GlaxoSmithKline and Bayer, have already promised saturation advertising. They have signed a sponsorship deal with the National Football League and hired Mike Ditka, the larger-than-life former N.F.L. coach, as a spokesman for Levitra, in the hope that the best way into your bedroom is through the television in your living room.
Just months away is another competitor, Cialis from Eli Lilly, which is under final review. What seems sure to unfold is a loud chest-thumping contest as the rivals put forward competing claims about the relative benefits of the three drugs.
GlaxoSmithKline and Bayer assert that Levitra acts somewhat more quickly than Viagra. Pfizer disputes this claim. Lilly, meanwhile, will be able to point out that Cialis is effective for 36 hours, instead of 8 to 12 hours for Viagra and Levitra.
"Why do men want that?" asked Carole Copeland, a spokeswoman for Lilly. "Men tell us that, when they take other pills, they feel like they're on a stopwatch, and that adds to the pressure they already feel. They would like a treatment that would disconnect taking a tablet from intimacy."

Indeed, in many countries where all three drugs are approved including
United Kingdom Australia, Britain, France and Germany Cialis outsells Levitra, although
Viagra still dominates those markets.
But GlaxoSmithKline and Bayer both badly need a successful product, and analysts expect that they will do everything they can to take advantage of Levitra's head start on Cialis in the United Kingdom.
But the companies have an enormous challenge ahead. Patient demand for drugs to treat impotence, not diagnoses by doctors, may determine Levitra's success so it will depend almost entirely on consumer marketing.
But neither company perhaps because of their roots in Europe, where drug ads are not allowed has distinguished itself as a marketer. Pfizer, on the other hand, is widely acknowledged as among the best in the business.

Moreover, Viagra rivals Coca-Cola as one of the most widely known brands in the world. GlaxoSmithKline and Bayer will have to spend money like Imelda Marcos at a shoe sale for Levitra to become as familiar as Viagra.
Pfizer has rarely had to explain how quickly or effectively Viagra works, because widespread media coverage of the drug got that job done. To distinguish their product, GlaxoSmithKline and Bayer will have to delve into the details, acknowledged Susan Hirsch, a spokeswoman for Levitra. The danger is that specifics could make the target customers squeamish.
Levitra's makers are hoping for this kind of bump. They point to studies that suggest that 152 million men worldwide and at least 10 million in the United Kingdom suffer from erectile dysfunction, the industry's preferred term for impotence. Some 90 percent of these men have never sought treatment.
But predictions of huge sales for the drug assume that these men are untreated either because they fail to recognize their problem, a common occurrence in some conditions, like irritable bowel syndrome, or because they do not know that there is an effective treatment. C. J. Sylvester, an analyst for UBS, said that neither of those circumstances applies to impotence.
"Who doesn't know about Viagra? But you should try Levitra" he asked.
