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.

Roche Ups the Stakes on Personalized Medicine

By Patricia Van Arnum, Pharmaceutical Technology.

Personalized medicine, which targets individualized treatment and care based on personal and genetic variations, holds much promise for the pharmaceutical industry. Several pharmaceutical majors continue to invest in this emerging field as evident by Roche’s $5.7-billion bid last week for Illumina, a provider of gene-sequencing tools and related analytics.

Roche, perhaps, more than any other pharmaceutical company, is banking heavily on the combination of diagnostics and drug development to drive pharmaceutical innovation. In reporting its 2010 results in February 2011, Roche reported that it had 12 new molecular entities in late-stage development, of which six were potential personalized healthcare medicines with planned companion diagnostic tests, which included Zelboraf (vemurafenib) and its companion diagnostic for BRAF mutation-positive metastatic melanoma. FDA approved Zelboraf for treating BRAF V600E mutation-positive, inoperable, or metastatic melanoma and the cobas 4800 BRAF V600 Mutation Test, a diagnostic test developed by Roche, in August 2011.

Earlier this month, the European Medicines Agency’s Committee for Medicinal Products for Human Use recommended that Zelboraf be granted full marketing authorization as a monotherapy for treating adult patients with BRAF V600 mutation-positive unresectable or metastatic melanom. The corresponding European Commission decision on the marketing authorization of Zelboraf is expected in February 2012. Marketing authorization submissions for Zelboraf also are under review by health authorities in Australia, New Zealand, Brazil, India, Mexico, Canada, and other countries worldwide.

Roche also is using its diagnostic strategy to support new indications for existing drugs. Last month, it reported that the cobas EGFR Mutation Test was CE-marked, an indicator of a product’s conformity with EU requirements, and is now commercially availabile in Europe and other countries that recognize the CE mark. The cobas EGFR Mutation Test is a companion diagnostic to identify patients with non-small-cell lung cancer (NSCLC) who harbor mutations in the EGFR (epidermal growth factor receptor) gene and who may benefit from treatment with anti-EGFR tyrosine kinase inhibitors, such as Roche’ Tarceva (erlotinib). Tarceva, an oral EGFR inhibitor, was first approved in September 2004 to treat locally advanced or metastatic NSCLC after failure of at least one other chemotherapy treatment. It later was approved by the European Commission in September 2011 as a first-line monotherapy in people with locally advanced or metastatic NSCLC with EGFR-activating mutations.

Other companies also are reporting success with certain personalized medicines. In August 2011, FDA approved Pfizer’s Xalkori (crizotinib) for treating locally advanced or metastatic NSCLC that expresses the abnormal anaplastic lymphoma kinase (ALK) as detected by an FDA-approved test. The agency approved the drug along with a diagnostic test for the ALK gene abnormality, Abbott Molecular’s Vysis ALK Break Apart FISH Probe Kit. Up to 7% of those patients with NSCLC, typically patients without a history of smoking, have the gene abnormality.

Although personalized medicines will likely hold only a small part of the overall pharmaceutical market by value and volume in the near term, these successes portend of a changing paradigm in drug development.

California Life Sciences to Partner with China

Posted under BIOCOM, Blog, China, Companies, Diagnostics, Emerging Markets, Funding, Global, IP, leadership, Life Science, Market Access, Medical Devices, Medical Supply, Pharmaceuticals, R&D, Startups, Universities, Videos by Ben Comer

BIOCOM, a trade group representing Southern California’s life sciences industry, is ramping up partnership efforts in China to meet an emerging desire for novel drug therapies.

While intellectual property (IP) protections and the Chinese government’s willingness to pay for expensive new products represent two large and lingering question marks, Joe Panetta, president and CEO at BIOCOM, said his last trip to China was surprising.

“We visited one of the largest pharmaceutical companies in China – Yangtze River Pharmaceuticals – which is pretty strongly government-backed and which has been long known to be a generics and traditional Chinese medicine company,” said Panetta, noting a statue of Mao Zedong in the company’s courtyard. “When I got there, not only did I see their long-established generics manufacturing facilities, but I also saw their 14- and 10-story innovative research towers that are under construction. They assured me that the future for them is not in generics, and the CEO said clearly to us: ‘I want to meet companies in San Diego, and I want to access new therapies that we can commercialize here.’”

Panetta said a portion of China’s population – by some estimates a portion as large as the total US population, according to Panetta – is becoming increasingly affluent, and has the “desire to access new therapies as well as the means to access new therapies.”

Despite a rising tide of affluence in major cities, many people living in China’s outer provinces are still in need of basic medical services, a problem China’s ambitious, $125 billion health reform initiative hopes to alleviate. “First they have to build delivery centers, and [the Chinese government] is talking about building hundreds of hospitals and thousands of clinics throughout the provinces in China, and they have to first deliver basic therapies and diagnostics and devices, but the question is how soon will it be before the government begins to take an interest in more innovative technologies,” said Panetta. “They have a long way to go, but to me, what that says is that there’s a lot of opportunity for a long time in China.”

The best way to enter the Chinese market is through partnerships, said Panetta, citing talks with companies residing in “large biotech parks in Shanghai and Beijing, and the China Medical City that’s being built from the ground up in Taizhou,” as well as US and European pharmaceutical companies that have a presence in China. “The Chinese would love for our companies to go over there and set up shop,” said Panetta. “What they tell us is that they want to learn how to innovate…I think the payback for our companies is clearly the 1.3 billion person market in China.”

BIOCOM hopes to facilitate partnerships with Chinese companies through conferences and trips to China, in order to “understand who we can build relationships with, what those relationships need to look like, and where we can build those relationships,” said Panetta. “[US] companies need to be careful about how much of their intellectual property they take to China when they create partnerships, and how much they keep [in the US],” said Panetta, and concerns remain about the level of talent and skill that exists, beyond the research level. “Several years ago, the discussion on Asia tended to gravitate toward outsourcing, low-cost research and low-cost early stage discovery efforts,” said Panetta. “That’s changed pretty drastically. It’s a terrific opportunity four our life sciences industry in Southern California,” he said.

First Chinese Product Development Partnership Targets Tuberculosis, Malaria, AIDS

A Chinese scientific foundation and a not-for-profit tuberculosis organization announced a partnership aimed at developing new medicines for underserved public health diseases.

Billed as the first Chinese product development partnership (PDP), the Global Health R&D Center of China (GHRC) hopes to discover and develop new treatments for tuberculosis (TB) and other diseases by collaborating with pharmaceutical companies, the Chinese government, academic institutions and other groups, according to a statement.

The GHRC was created through a partnership between The International Scientific Exchange Foundation of China (ISEFC), a translational sciences group, and the TB Alliance, a not-for-profit organization focused on developing new and better TB medications.

Mel Spigelman, president and CEO of the TB Alliance, said in an email that pharmaceutical companies stand to gain from sharing resources, such as intellectual property, with the GHRC. “The GHRC will offer companies financial and world-class discovery and clinical development resources to advance compounds for neglected diseases that they otherwise may not be able to [develop] on their own,” said Spigelman. “In addition, companies will establish strong working relationships with key discovery, regulatory, and clinical resources in the fastest-growing pharmaceutical market in the world.”

The TB Alliance has drug development partnerships with AstraZeneca, Bayer, GSK, Novartis, Sanofi-Aventis, and Tibotec, and is currently managing three drug candidates in clinical trials, according to organization’s website. Spigelman declined to specify which compounds the TB Alliance itself will contribute to the GHRC.

“The vision of the GHRC is to focus on translational medicine for public health and bridge the innovation gap that currently exists into new treatments and cures,” said Geng Jianyue, secretary-general assistant of the ISEFC, in a statement. In China alone, some 1.3 million people develop active TB annually, and 150,000 die from the disease each year, according to the TB Alliance.

A recent World Health Organization (WHO) report found that only a 10% of the multidrug-resistant tuberculosis (MDR-TB) cases identified globally received treatment in 2009. The WHO report called multidrug-resistant and extensively drug-resistant tuberculosis a global epidemic, and TB in general kills almost 2 million people each year, according to the TB Alliance. The announcement of the GHRC coincides with World TB Day, which is celebrated on March 24 each year, to commemorate Robert Koch’s discovery of TB bacillus, the cause of the disease.

While access to treatment remains a major problem in many of the 27 countries most burdened with MDR-TB, the treatments themselves, many over forty years old, present further difficulties, since first-line drugs like isoniazid, ethambutol, pyrazinamide and rifampin require a six to nine month regimen. Failure to adhere to a treatment regimen can result in drug resistant strains of TB, which require second-line drugs, many with severe side effects.

In addition to developing new TB treatments and addressing other public health diseases in China, the GHRC will also develop compounds for the rest of the developing world, according to Spigelman. “Global development programs will likely be partnered with disease-specific PDPs or with global pharmaceutical companies, who will then work with GHRC to register the compounds throughout the world,” he said.
