Can Merck Field a Psoriasis Blockbuster?

By Maxx Chatsko, The Motley Fool

Targeting psoriasis, rheumatoid arthritis, and other immune diseases has created some massive markets over the last decade. How massive? The market was sized up at an estimated $72.2 billion in 2010, according to BCC Research — and growth isn’t slowing any time soon. That’s good news for patients, too. The pharmaceutical industry’s fascination with an improved understanding of biologics has led to dozens of drugs that treat the underlying causes of diseases, rather than small molecules of years past that only treated symptoms.  

Few companies haven’t joined the rush to develop biologics and novel small molecule classes to treat immune diseases. While some companies got a big head start over the field, next-generation therapies are being developed in pipelines across the industry. Merck is one company looking to capitalize on the trend and will shortly begin phase 3 trials on its leading psoriasis biologic therapy candidate. Going by the catchy pipeline name of MK-3222, the drug has huge potential if it ever receives approval from the Food and Drug Administration, or FDA.

About that competition I mentioned…
Older therapies aren’t exactly losing their grasp on the markets they took by storm just yet. A quick look at 2012 sales data from the first three biologics approved that work by inhibiting the TNF-alpha protein — integral to immune system communication — shows exactly that.

Aside from the big three, there are newer therapies on the market and in development that target TNF-alpha indirectly by inhibiting the proteins further upstream in the cellular communication chain. For instance, Johnson & Johnson’s Stelara binds to interleukin 23 and interleukin 12, which regulate TNF-alpha production. The therapy has been approved for psoriasis and is in late stage trials for Crohn’s disease and ankylosing spondylitis.

The biggest advantage for new therapies may lie in dosing schedules. Consider that during a 12-week study comparing Stelara to Enbrel, the TNF-alpha inhibitor was administered twice a week for the length of the study, while the drug candidate was administered just twice over the same period. Stelara still managed to beat Enbrel in high-dose groups with 71% and 49% of patients responding, respectively.   

Is it too late for Merck?
The dosing regimen of Stelara raises the bar significantly for all therapies. However, Merck’s MK-3222 has essentially the same requirements; administered twice in the first four weeks of treatment and then once every 12 weeks thereafter. The two therapies work in slightly different ways, too, with MK-3222 targeting a different region of interleukin 23 while sparing interleukin 12. In theory, that could make the drug less destructive to a patient’s immune system, which is the biggest drawback to many immune disease therapies.

Is There a "First-Mover" Advantage in Biotech?

By Keith Speights, The Motley Fool

Filed under:

The early bird gets the worm. Business gurus might not use that old phrase, but many of them tout the principle behind it. They tell anyone who will listen that getting to market first provides significant advantages. Customers will gain familiarity with the first product on the market and be much less likely to switch to another product later. That’s what the gurus say, but is it true?

One biotech that certainly hopes they’re right is VIVUS . The company’s weight loss drug Qsymia gained FDA approval last July. VIVUS quickly moved to launch the drug, with Qsymia reaching the market in September.

However, Arena Pharmaceuticals is nipping at its heels. Arena’s Belviq actually gained FDA approval a few weeks earlier than Qsymia. The company hasn’t been able to launch the drug commercially, though, as it awaits scheduling by the Drug Enforcement Agency.

Will VIVUS be able to benefit from a first-mover advantage? Or is this concept really not applicable to biotech? 

Birds of a different feather
If history is a guide from a different area of biotech, VIVUS might be in for a challenge. Way back in 1998, Amgen‘s Enbrel became the first TNF inhibitor to receive FDA approval for treating rheumatoid arthritis. Regulatory approval for other indications followed over the next few years.

By any measure, Enbrel was a huge success. But another TNF inhibitor followed closely in its footsteps. Johnson & Johnson’s Remicade gained FDA approval for treating rheumatoid arthritis in 1999. The two drugs battled it out by themselves until 2002, when the FDA approved AbbVie’s Humira.

So, how well did Amgen’s first-mover advantage hold up? If we fast forward the clock to 2012, the sales for the three drugs tell the story. Amgen made $4.2 billion from Enbrel. Add to that figure another $3.7 billion from Pfizer‘s sales of Enbrel outside the U.S. That gives Enbrel a total of $7.9 billion in 2012 sales. 

Second-to-market Remicade trailed Enbrel with $6.1 billion in sales. AbbVie’s 2012 sales for Humira totaled $9.3 billion, making it the world’s top-selling drug. While Enbrel and Remicade also rank in the top five drugs in terms of worldwide sales, the laggard in getting to market became the leader.

One slippery worm
Of course, second or even third place isn’t all that bad, even for a first-mover, when sales are great for everyone. So far, though, VIVUS is finding that the market for weight loss drugs isn’t as easy to crack as it had hoped.

U.S. sales for Qsymia have been disappointing — only around $2 million in 2012. VIVUS also has faced challenges in gaining approval for reimbursement for the drug, although the company has made progress on that front.

Europe has proved to be even more difficult. The Committee for Medicinal Products for Human Use, or CHMP, rejected Qsymia (known in Europe as Qsiva) in October. VIVUS appealed the decision, but CHMP stood by its earlier negative decision. Another clinical trial focusing on cardiovascular …read more
