Like a lot of biotech investors, Royalty Pharma sees blockbuster potential in Biogen Idec's ($BIIB) experimental BG-12. The New York-based buyer of royalty interests in biopharma products has laid down $761 million for an interest in potential earn-outs to former shareholders of Fumapharm.

Weston MA-based Biogen, the world's largest provider of multiple sclerosis drugs, snapped up Fumapharm in 2006 to acquire BG-12, a potential blockbuster oral MS treatment. The Royalty Pharma deal gives Fumapharm's former shareholders an early reward for their interest in the hottest late-stage drug in Biogen's pipeline and follows two positive Phase III studies of the drug for combatting flare-ups of the autoimmune disease. The success of the program thus far has helped Biogen's shares soar.

Royalty Pharma has made a huge bet on the future of BG-12, which could become the second approved oral drug for treating attacks of the nerve-damaging disease after Novartis' ($NVS) Gilenya. In recent months Biogen Idec has filed for approvals of the drug in the U.S. and Europe, and the biotech giant is gearing up for a major U.S. launch of the MS treatment in 2013. RBC Capital Markets has estimated peak annual sales of BG-12 to hit up to $3 billion. (Royalty is also gaining a stake in the earn-outs tied to a lesser-known drug from Fumapharm called Fumaderm, a treatment used in Germany for plaque psoriasis.) 

"We are pleased to acquire an interest in one of the most promising new therapies addressing the needs of patients with relapsing-remitting multiple sclerosis," Royalty Pharma CEO Pablo Legorreta said. "The combination of efficacy, safety and tolerability of BG-12 shown in the DEFINE and CONFIRM Phase 3 trials, the oral dosing regimen and Biogen Idec's deep commitment to this disease category, leads us to believe that BG-12 has blockbuster potential."

Dare to Compare: Genzyme Bets on MS

Riding positive data on a late-phase multiple sclerosis drug, Genzyme execs talked up the company’s willingness to go head-to-head against Rebif, EMD Serono and Pfizer’s blockbuster beta interferon.

Genzyme execs didn’t go so far as to reiterate former CEO Henri Termeer’s 2010 prediction of $3 billion plus in potential sales for Lemtrada (alemtuzumab), but they did tout clinical results suggesting a reversal in MS-related disability for some patients.

New phase III data from Genzyme’s CARE-MS II was unveiled yesterday at the American Academy of Neurology’s annual meeting, and while Biogen Idec’s BG-12 (dimethyl fumarate) – a twice or thrice daily oral drug – has gotten more and better attention over the last year, Michael Panzara, therapeutic area head, multiple sclerosis, immune diseases and neurology at Sanofi-owned Genzyme, says consider the trial design. Without speaking directly to other clinical programs in the MS space, Panzara tells PharmExec that Genzyme’s decision to use an active comparator, rather than a placebo, raises the bar. “When you have a therapy as efficacious as [Lemtrada] with a risk profile that’s manageable – but it does have a risk profile – you want to set a standard of going against what is viewed as the most effective platform therapy, which is Rebif,” says Panzara.

This strategy, while riskier than testing against placebo, pays dividends if the results suggest superiority, according to Panzara. “I think [active comparator data] will be viewed favorably by physicians, who practice medicine and have to make these treatment decisions every day,” says Panzara. “And I would hope regulatory authorities would take notice as well, because they’re always looking to better understand risk and benefit versus therapies that are already available, especially in Europe.” Bill Sibold, senior vice president, head of multiple sclerosis at Genzyme, says the comparator data will aid in reimbursement discussions with payers, so the risk of knockout in a head-to-head battle is warranted. “I think most companies hesitate to do [active comparator] trials, so I think it says a lot about Genzyme and the approach that we’ve taken, specifically with this program.”

But is Rebif still the lead contender in MS? Raghuram Selvaraju*, head of healthcare equity research at Aegis Capital, says going head-to-head against Rebif in MS is akin to playing a game of chicken and waiting a bit longer before turning away. “Rebif is no longer the standard as far as efficacy is concerned…that honor now belongs to [Novartis'] Gilenya,” says Selvaraju. Gilenya was approved in late 2010, which illustrates a key difficulty with comparator trials; when Lemtrada went into the clinic, Gilenya wasn’t yet on the market. Concerns regarding Gilenya in patients with a history of cardiovascular issues have recently reemerged, however, which could add a few pounds to the scale for Lemtrada.

If approved – Genzyme is on track to file for US and EU approval of Lemtrada for relapsing MS this quarter, according to Panzara and Sibold – the company has worldwide rights and the lead role in development and commercialization, although  Bayer HealthCare retains an option to co-promote the drug, and would receive contingent payments based on sales, according to a company statement. Sibold says Genzyme will be hiring sales reps closer to launch. “You’ll see a lot of growth” with respect to marketing and promotional capabilities in MS, says Sibold. Sales force headcount and the specifics of a co-promote with Bayer are details for a later date, he said.

Sibold added that Genzyme has the modest goal of “becoming leaders in MS,” and that “starts with the portfolio.” In addition to Aubagio (teriflunomide), a phase III once-daily oral treatment with “efficacy similar to the platform therapies,” according to Sibold, Genzyme is “looking within our internal pipeline, and looking externally for ways to continually evolve our MS franchise…our plan is to be here for a long time, so we need the supporting portfolio to do so,” says Sibold.

Lemtrada is administered as an infusion over five consecutive days, and then again one year later, for three days. Autoimmune side effects, particularly hypothyroidism and hyperthyroidism, occurred at a rate as high as 30% of patients during phase II, but were down at 15.9% for the CARE-MS II study. A rare autoimmune disorder called immune thrombocytopenic purpura, or ITP, occurred in less than one percent of patients. Only 5% of the Rebif comparator arm had autoimmune thyroid side effect. As a result, analysts have been cool on Lemtrada, but Panzara insists that most of the occurrences were mild to moderate, and they’re well managed. “We’ve gotten very good at detecting and managing [thyroid-related autoimmune side effects], and it doesn’t cause people to leave the trial early, or refuse additional doses; it doesn’t impact that,” says Panzara. “It’s easy to call attention to [Lemtrada’s] side effects, without calling attention to the risks of MS itself,” says Panzara. Of the benefit side of the coin, the CARE-MS II study used the Expanded Disability Status Scale (EDSS) to show that 29% of patients with an EDSS score of two or more – two is characterized as “minimal disability” – had a preexisting disability that was reversed, says Panzara. “Those patients had a reduction in their disability scores that was sustained, so that is a reversal in what they had before,” he says.

Lemtrada’s active ingredient – alemtuzumab – is already on the market in a subcutaneous formulation known as Campath, indicated for the treatment of certain cancers. In 2010, Genzyme execs publicly considered discontinuing Campath and giving it to cancer patients for free, to prevent off-label MS usage, but Sibold wouldn’t elaborate on the company’s current strategy with respect to Campath, beyond expressing a “commitment to ensuring that patients who need Campath receive it.” The pricing issue is problematic, says Selvaraju. “Currently, a dose of Campath that is over 10 times higher than the dose being used in MS patients is sold for roughly $30,00 per year. Just as Genentech/Roche found with their Avastin/Lucentis problem, Genzyme/Sanofi are going to run into trouble if they ask reimbursement agencies to swallow a higher price than roughly $3,000 per patient per year for alemtuzumab in MS,” he says. Taking Campath off the market and providing it for free to cancer patients while putting a premium price on the MS version “is probably not going to fly with reimbursement agencies either here or in Europe,” says Selvaraju.

Lemtrada has patent protection in the US until 2017, and most of Europe until 2014, the company said.

Sanofi’s Lemtrada beats Rebif in head-to-head MS showdown

Posted under Blog, Companies, Diagnostics, Funding, Lemtrada, Medical Devices, Medical Supply, multiple sclerosis, Pharmaceuticals, Rebif, Sanofi, Startups, Universities, Videos by john

Sanofi has rolled out a fresh set of late-stage Lemtrada (alemtuzumab) data demonstrating its superiority to Rebif in a head-to-head matchup for multiple sclerosis. One of the key programs acquired in Sanofi's ($SNY) $20 billion Genzyme buyout, Lemtrada is increasingly looking like an odds-on winner at the FDA. And the pharma giant's success with the drug--alongside its other Phase III MS program--has inspired the pharma giant to spread its global BD net in search of other treatments.

Patients taking Lemtrada in the study scored better at slowing disease progression, with a sizable minority doing better as a larger proportion of Rebif patients faltered. Altogether 29% of the Lemtrada patients scored better on disability, compared to 13% for the Rebif group. Close to two thirds of the patients were relapse-free at 2 years, compared to 47% in the Rebif arm.

"To date, a key goal for MS treatment has been to delay the worsening of disability," said Jeffrey Cohen, M.D., an MS investigator. "Patients in the study whose prior MS treatment was inadequate at preventing relapses and received alemtuzumab in the CARE-MS ll trial experienced a slowing or reversal of their disability."

For Genzyme MS chief Michael Panzara, the bottom line is simple: "Alemtuzumab versus Rebif improves function; that's unique," he told Bloomberg.

Not everyone is happy about the drug's tox profile, though. Investigators have already noted that 16% of the patients taking the drug developed an autoimmune related adverse event, compared to 5% for Rebif patients.

But that AE profile hasn't reduced Sanofi's public confidence. Panzara went on to tell Bloomberg that Sanofi is always looking for more MS drugs to add to the pipeline, which includes Aubagio. "You can't have a world-class MS organization if you don't fill up the pipeline at all stages of development."

Biogen Idec builds blockbuster case for new MS drug BG-12

Posted under BG-12, Biogen Idec, blockbuster, Blog, Companies, Diagnostics, Doug Williams, Funding, Medical Devices, Medical Supply, multiple sclerosis, Pharmaceuticals, Pipeline, Startups, Universities, Videos by john

Biogen Idec is backing up its blockbuster expectations for the MS drug BG-12 with a slate of efficacy and safety data gathered in a late-stage study. Readied for a scientific review, Biogen ($BIIB) execs touted the safety profile of the drug, which has proven to be Exhibit A in the biotech's case for a successful turnaround.

"The safety profile has continued to hold up nicely from one study to the next," Doug Williams, Biogen's softspoken R&D chief, tells Dow Jones. Add it all up, he adds, and you'll find compelling reasons why the oral treatment--now under review--"should be front-line therapy for patients." 

At two years of therapy patients in the 1400-subject CONFIRM study most frequently had to deal with flushing and some common GI issues like nausea and diarrhea. But incidents of these side effects also quickly dissipated after treatment began. And the control arm also experienced dramatically high rates of adverse events, not at all uncommon in MS. Patients have been willing to subject themselves to significant risks in the past in order to benefit from new treatments.

This is the second batch of late-stage data to be presented to regulators. "Results from CONFIRM complement the profile we have seen for BG-12 throughout its clinical development program, which now includes robust data sets from two global, placebo-controlled Phase III pivotal studies with more than 2,600 multiple sclerosis patients," said Williams.
