Biogen Idec lays out a convincing blockbuster case for MS pill BG-12

Following fast on the heels of Sanofi's ($SNY) approval of the oral multiple sclerosis (MS) drug Aubagio, Biogen Idec ($BIIB) has outlined its full pivotal case for BG-12, with an impressive ...
Scientists published the results from the two big Phase III studies for BG-12(dimethyl fumarate), demonstrating that both of the treatment regimens studied in the pivotal program cut the annual MS relapse rate by about half. The twice-daily dose was associated with a drop in new or expanded lesions by 71% to 99%. And there was a 38% reduction in progression to disability.
Just as important, BG-12 delivered fresh evidence of its relatively clean safety profile, a big concern in a field now dominated by treatments associated with some severe, and occasionally fatal, side effects. Flushing and gastrointestinal symptoms, like vomiting, were the most common side effects, but tended to taper off after the first two weeks of therapy. The results confirmed the general safety profile of a comparable fumarate already in use, which is likely going to add to its appeal to regulators.

"The safety track record is well known and appears to be very strong," study leader Robert Fox told The New York Times.
"Because MS is a chronic disease, we look for treatment options that not only control relapses but also slow patients' disease progression for as long as possible," said Ralf Gold, the lead author of the DEFINE study published inThe New England Journal of Medicine. "In DEFINE, dimethyl fumarate demonstrated efficacy, as well as positive safety and tolerability profiles, which is a very attractive combination for an MS treatment."
While Biogen Idec CEO George Scangos inherited the late-stage BG-12 program from his predecessor at the company, it's been Exhibit A for investors making the case for the big biotech's turnaround. Biogen is a longtime leader in the MS field, a fact that has not been lost on analysts like Cowen's Eric Schmidt, who has bullishly forecast peak sales at $3 billion. Others believe that an overly rosy projection on revenue is likely to leave some backers unhappy if the drug falls short of that high mark. The market for MS has grown to $12 billion.
Biogen Idec's share price has almost tripled over the past two years.

Το BG12 ειναι εστερας του φουμαρικου οξεως και παροτι εχει αποτελεσματα στη μιτοχονδριακη λειτουργια προκαλωντας οξειδωση ωστε να ενεργοποιει τα μιτοχονδρια να αντιδρασουν παμπολες φυσικες ουσιες οπως οι επιγαλοκατεχινες τσαγιου, το σιλυβο (σπορος γαιδουραγκαθου), η κουρκουμινη κ.α. εχουν παρομοια και ισχυροτερη δραση χωρις τις εστω λιγες παρενεργειες του.
Και για να μιλησουμε με αποτελεσματα και ερευνες ενα φυσικο συμπληρωμα το protandim (http://www.protandim.com/what-is-protandim/) που περιεχει κουρκουμινη σιλυβο επιγαλοκατεχινες και καποιες αλλες ουσιες σε πολυ μικρες ποσοτητες μαλιστα εχει καλυτερα αποτελεσματα απο το συγκεκριμενο "φαρμακο":

Biotechnology company Biogen Idec Inc said U.S. health regulators extended by three months the review date of its much-awaited multiple sclerosis (MS) drug BG-12, but analysts said the delay was only a minor setback.

Shares of Biogen were down 2 percent at $150.72 in morning trading on the Nasdaq.

The stock has risen more than 50 percent over the past 12 months, largely on optimism about BG-12, which showed robust results in trials and had no safety concerns.

Analysts said the delay would push the review date to March, but added such extensions were not uncommon.

"The registrational studies for BG-12 - DEFINE and CONFIRM - enrolled about 1,200 and 1,400 patients, respectively. Given the size and complexity of the filings, we are not surprised that the FDA would require additional time to review the application," Barclays Capital analyst Anthony Butler said.

The U.S. Food and Drug Administration said it needed additional time to review the application, but did not ask for additional studies, according to Biogen.

Butler and Wells Fargo Securities analyst Brian Abrahams pointed out that Sanofi's oral MS drug Aubagio also had its review extended earlier this year, but was later approved.

BG-12, also known as dimethyl fumarate, would be the second oral MS drug on the market, competing with Novartis AG's Gilenya.

Analysts expect sales of $390 million and $980 million for BG-12 in 2013 and 2014, Barclays's Butler said in a note.

The oral drug is currently also under regulatory review in the European Union, Australia, Canada and Switzerland.

Biogen also markets Avonex and Tysabri to treat relapsing-remitting MS, the most common kind of MS.

Multiple sclerosis affects 400,000 Americans and 2.5 million people worldwide, according to the National Multiple Sclerosis Society.
