Merck KGaA: Oral Investigational Treatment Cladribine Tablets for Multiple Sclerosis Significantly Reduced Relapse Rate in Phase III Pivotal Trial





• Two-year primary efficacy endpoint of CLARITY trial met: 58% relative
reduction in annualized relapse rate in the low total dose treatment group
and 55% in the high total dose treatment group

• Submission for registration of cladribine tablets planned for mid-2009

• Cladribine tablets are the first oral investigational multiple sclerosis
treatment to complete a two-year pivotal study

Darmstadt, Germany, January 23, 2009 – Merck KGaA and its Merck Serono division
announced today that the CLARITY1 Phase III pivotal trial of its proprietary oral
formulation of cladribine (cladribine tablets) met the two-year primary endpoint of
clinical relapse rate reduction in patients with relapsing-remitting multiple sclerosis
(MS).

The two cladribine tablet treatment groups of the study, assessing different dose
regimens, demonstrated a statistically significant reduction in the annualized rate of
relapses compared to placebo. Patients from the lower total dose group experienced a
58% relative reduction in annualized relapse rates with respect to placebo (0.14 versus
0.33 for the placebo group; p<0.001). Patients from the higher total dose group
experienced a 55% relative reduction in annualized relapse rates with respect to
placebo (0.15 versus 0.33; p<0.001).

Overall, the frequencies of adverse events were low in the cladribine tablet treatment
groups and were comparable to that observed in the placebo group. Lymphopenia, an expected event based on the presumed mechanism of action of cladribine, occurred
more frequently in the cladribine tablet treatment groups. With the exception of
lymphopenia, the most frequently reported adverse events in the three study groups
were headaches and nasopharyngitis.

“We believe the CLARITY data mark an important milestone in the assessment of
investigational oral treatments for multiple sclerosis and that cladribine tablets have the potential to make a real difference in the lives of patients,” said Elmar Schnee, Executive Board Member with responsibility for the Pharmaceuticals business sector.

“Based on the successful completion of the CLARITY study, we plan to submit cladribine tablets for registration to the EMEA and to the FDA for mid-2009."

Secondary endpoints of the CLARITY study were also met, including reduction of lesion activity as measured by magnetic resonance imaging (MRI), proportion of subjects relapse-free and disability progression. Full study results will be submitted for
presentation at an upcoming scientific meeting.

The CLARITY study was a two-year (96 weeks), randomized, double-blind, placebo controlled, international trial. It enrolled 1,326 patients with relapsing-remitting MS
according to the revised McDonald criteria2. Study participants were randomized to one
of three different treatment groups consisting of two different dose regimens of
cladribine tablets or matching placebo tablets (1:1:1 ratio). Cladribine tablets were
given in two or four treatment courses in the first year, with each course consisting of once daily administration for four to five consecutive days, which means study patients took cladribine tablets for only 8 to 20 days during the year. In the second year, two treatment courses were administered to all patient groups. The primary endpoint of the CLARITY study was the qualifying relapse rate at 96 weeks. Secondary endpoints included MRI endpoints3, proportion of subjects relapse-free and disability progression at 96 weeks. Out of the 1,326 randomized patients, 90% of patients treated with cladribine tablets completed the study (92% in the lower total dose group and 89% in the higher total dose group) compared to 87% in the placebo group.

2 The McDonald criteria are diagnostic criteria for MS. In April 2001 an international panel in association with the National Multiple Sclerosis Society (NMSS) of America recommended revised diagnostic criteria for MS. They make use of advances in MRI imaging techniques and are intended to replace the Poser criteria. The new criteria facilitate the diagnosis of MS in patients who present with signs and symptoms
suggestive of the disease. The McDonald criteria for the diagnosis of multiple sclerosis were revised in 2005 to simplify and speed diagnosis, while maintaining adequate sensitivity and specificity.

3 The exact correlation between MRI findings and the current or future clinical status of patients, including disability progression, is unknown.

About cladribine tablets

Merck Serono’s proprietary oral formulation of cladribine (cladribine tablets) is currently being evaluated in Phase III as a treatment for patients with relapsing forms of multiple sclerosis (MS). Cladribine is a small molecule that may interfere with the behavior and the proliferation of certain white blood cells, particularly
lymphocytes, which are thought to be involved in the pathological process of MS.
The clinical development program for cladribine tablets includes:

- The CLARITY (CLAdRIbine Tablets Treating MS OrallY) extension study: a two-year placebo-controlled extension of the CLARITY study, designed to provide data on the long-term safety and efficacy of extended administration of cladribine tablets for up to four years

- The ORACLE MS (ORAl CLadribine in Early MS) study: a two-year Phase III placebo-controlled trial designed to evaluate the efficacy and safety of cladribine tablets as a monotherapy in patients at risk of developing MS (patients who have experienced a first clinical event suggestive of MS). This trial was announced in September 2008.

- The ONWARD (Oral Cladribine Added ON To Rebif New Formulation in Patients With Active Relapsing Disease) study: a Phase II placebo-controlled trial designed primarily to evaluate the safety and tolerability of adding cladribine tablets treatment to patients with relapsing forms of MS, who have experienced breakthrough disease while on established interferon-beta therapy. This trial was announced in January 2007.

Cladribine tablets have been granted a fast track designation by the US Food and Drug Administration based on the need for an oral therapy in a subset of patients with relapsing forms of multiple sclerosis.

Novartis launches Extavia®, a new therapeutic option to help patients combat devastating symptoms of multiple sclerosis





# Multiple sclerosis (MS) causes progressive disability and affects 2.5 million people worldwide including many young adults[1]

# Extavia offers patients and physicians a new branded version of standard-of-care interferon beta-1b

# Approved to treat MS patients from first signs of active disease to more advanced, relapsing forms

# Launch marks start of planned long-term partnership between Novartis and MS community

Basel, January 22, 2009 - Novartis has today announced the launch of Extavia®, a new version of the standard-of-care for relapsing forms of multiple sclerosis (MS), providing patients and physicians with an alternative option to help manage this devastating disease.

Extavia, a new branded version of interferon beta-1b, is available initially in Germany and Denmark with other European launches to follow during 2009. It is approved to treat a broad range of patients, from those with early signs of MS to those with more advanced relapsing forms of the disease.

"Extavia will provide patients and physicians with an additional option for receiving a mainstay of care in MS," said Trevor Mundel, MD, Global Head of Development at Novartis Pharma AG. "This important first step also opens the way for Novartis to build supportive partnerships with the MS community and lays the foundations for providing innovative approaches to MS care."

Extavia is the same medicinal product as Betaferon®*, an interferon beta-1b. This has a well characterised efficacy and safety profile with more than 700,000 patient-years' experience[2] and a 17-year track record of clinical use - the longest for any interferon beta in the treatment of MS[3].

MS is estimated to affect up to 2.5 million patients worldwide and is one of the leading causes of neurological disability in young adults1. The disease typically presents in relapsing forms involving acute self-limiting attacks of neurological dysfunction (or "relapses"), followed by complete or partial restoration of function.
Data have shown that interferon beta-1b produces a 34% reduction in annualized relapse rates (p<0.001), and patients are almost twice as likely to remain relapse-free for over two years compared to those on placebo (31% vs. 16%, p=0.007)[4]. Treatment with interferon beta-1b can also slow disease progression. After two years, nearly three-quarters of patients who had experienced a single episode of neurological disease lasting at least 24 hours did not progress to clinically definite MS[5].

The launch of Extavia in Europe by the Pharmaceuticals Division of Novartis marks the beginning of a long-term commitment to meet the therapeutic needs of the MS community. This will include the establishment of a support program for Extavia users that will foster cross-communication between patients and their physicians and nurses. In turn, this will lay the foundations for future potential innovations in MS therapy. The rollout of Extavia in key EU countries is expected during the coming months.

Novartis acquired the rights to its own branded version of interferon beta-1b in an agreement with Bayer Schering, the company that markets Betaferon. In backing Extavia, Novartis brings over 50 years of neuroscience expertise and resources to the MS community. This expertise has helped to pioneer early breakthrough treatments for a number of neurological and pathological conditions, some of which remain important therapies to this day.

MS is a chronic autoimmune disease of the central nervous system that causes inflammation and neurodegeneration. Pathology is characterised by the destruction of myelin, which helps neurons carry electrical signals in the brain[6]. The disease causes problems with muscle control and strength, vision, balance, sensation and mental function[6].

The beneficial effects of interferon beta are believed to be due to its modulation of the immune system to reduce inflammatory damage. Specifically, interferon beta limits the activation of immune cells that attack myelin, suppresses the production of inflammatory cytokines - a type of protein that amplifies the inflammatory response causing damage to myelin - and stimulates the production of anti-inflammatory cytokines.

Extavia has been filed with the US Food and Drug Administration for the treatment of relapsing forms of MS to reduce the frequency of clinical exacerbations (or relapses). Patients with MS in whom efficacy has been demonstrated include those who have experienced a first clinical episode and have features consistent with MS as shown by magnetic resonance imaging (MRI)[7].

Extavia is administered by subcutaneous (or under the skin) injection. Patients will have the choice of using either a fine (30 gauge) needle for manual injection or a convenient autoinjector.

New Interferon Formulations Promise to Eliminate Injections in Multiple Sclerosis Treatment





SAN DIEGO, CA January 12, 2009/MarketWire/-- Nerveda Inc. and Aegis Therapeutics
LLC today announced preclinical results from their joint collaboration aimed at
developing non-injectable formulations of the beta-interferons. The beta interferons,
beta-1a (tradename Rebif®), and beta 1b (tradenames Betaseron® and Betaferon®) are
closely related injectable protein drugs in the interferon family that are used to treat both the relapsing-remitting and secondary-progressive forms of multiple sclerosis (MS). The beta interferons are currently administered by subcutaneous injection and have been proven clinically to slow the advance of multiple sclerosis and reduce the frequency of attacks. Current worldwide combined annual sales of Rebif®, Betaseron® and Betaferon® are approximately $4 Billion.

Because proteins are large and fragile molecules, they cannot be administered orally
and are typically administered by injection. They are often subject to instability due to aggregation of the protein molecules – particularly upon storage and handling at nonrefrigerated temperatures. The resulting protein aggregates are more poorly absorbed
into the blood stream upon injection due to their increased size, and induce development of circulating antibodies to interferon in patients that reduce the effectiveness of the drug over time.

Leading medical scientists at Johns Hopkins University, expert in the treatment of
neurological diseases, in collaboration with Nerveda and Aegis have applied Aegis’
Intravail® transmucosal absorption enhancement, and ProTek® protein stabilization
technologies to address these problems and have demonstrated for the first time that the beta interferons can be administered intranasally to prevent nerve damage in preclinical animal models of multiple sclerosis. In addition, the new formulations were shown to reduce or eliminate the immunogenicity of Betaseron® and Rebif®, administered either by injection or intranasally, while substantially increasing stability in a stress test involving constant agitation at elevated temperatures for extended periods of time.

Dr. Edward Maggio, Ph.D., CEO of Aegis Therapeutics, who participated in the
research, said, “since interferons will continue to be the foundation of MS therapy, it is critical that non-invasive delivery options for patients be developed.” Maggio also indicated, “the reduction in immunogenicity and the increase in stability also address a significant unmet need of the currently available beta-interferon therapies.”
Nerveda plans to begin testing the new formulation in clinical trials in early 2009 in
collaboration with clinicians and scientists at John Hopkins University Medical Center
and other sites.

“We are also beginning discussions with potential marketing partners to explore commercialization options in Europe and the rest of world excluding the U.S.,” Chief Executive Officer Ron Cohen said in a written statement. “Achieving these milestones will bring us closer to our goal of making Fampridine-SR available to the many people with MS who may benefit from it.”

MS Relapse-Rate Higher in Adolescent-Onset Patients




By Michael Smith, North American Correspondent, MedPage Today
Published: January 12, 2009

Reviewed by Zalman S. Agus, MD; Emeritus Professor
University of Pennsylvania School of Medicine.

BOSTON, Jan. 12 -- When multiple sclerosis symptoms start in adolescence, the later annual relapse rate is nearly three times as great as it is for adult-onset disease, researchers here said.

The finding suggests that adolescent-onset MS has a more inflammatory disease course, according to Tanuja Chitnis, M.D., of Massachusetts General Hospital, and colleagues.

But the biological basis of the difference remains unclear and requires more study, Dr. Chitnis and colleagues said in the January issue of Archives of Neurology.

Several studies have shown that initial disease progression is slower in patients whose disease begins before the age of 18, the researchers said, but have differed on rates of relapse.

To clarify the issue -- and see whether the slower progression is related to relapse rates -- Dr. Chitnis and colleagues studied patients treated in the pediatric and adult MS centers at Massachusetts General and Brigham and Women's after July 2001.

Patients were eligible if treatment started within 12 months of the first symptom and were followed for at least a year. All told, the researchers identified 110 adult-onset patients and 21 whose disease started before they were 18.

The main outcome measure was annualized relapse rate, defined as the number of relapses divided by the number of person-years at risk. Rates for the adult and younger groups were compared using a proportional means model, as well as a negative binomial regression that excluded the first attack.

In both models, the researchers found that the annualized relapse rate was significantly higher in the younger cohort. Specifically:

* When the first attack was included, adolescent patients had an annualized rate of 1.4, compared with 0.65 for adult-onset patients. The difference was significant at P0.001 and yielded an adjusted rate ratio of 2.81 (with a 95% confidence interval from 2.07 to 3.81.

* Excluding the first attack yielded a pediatric rate of 1.13 and an adult rate of 0.4, also significantly different at P0.001.The adjusted rate ratio was 2.93 (with a 95% confidence interval from 1.93 to 4.46).

When the researchers controlled for the effects of disease-modifying treatment -- such as interferons, glatiramer acetate (Copaxone) or oral immunosuppressants -- the difference remained significant, with rate ratios of 2.82 and 3.02, depending on the model.

And when age was treated as a continuous variable, the age at onset was significantly associated with relapse rate at P0.001, Dr. Chitnis and colleagues found.

While several studies have shown that disease progression is slower in adolescent-onset cases, the researchers said they were unable to show that in this case because of the relatively short disease duration.

But if that is so, Dr. Chitnis and colleagues argued, the finding that younger patients have more relapses implies "greater plasticity, less neurodegeneration, and potentially more repair and remyelination in the younger nervous system."

The authors pointed out that "it remains possible that patients with more severe pediatric-onset MS were selectively evaluated at our centers. However, distance from the center, a proxy measure for referral bias, which has been shown to influence clinical characteristics in prior articles in the neurology and oncology literature, was not different between our pediatric-onset and adult-onset groups."

The study was supported by the National Multiple Sclerosis Society. The researchers did not report any conflicts.

UPDATE 1-Biogen moves long-acting Avonex to final trial-CEO



By Deena Beasley

LOS ANGELES, Jan 7 (Reuters) - Biogen Idec Inc (BIIB.O: Quote, Profile, Research) has moved a long-acting version of its multiple sclerosis drug, Avonex, directly into trials designed to meet requirements for regulatory approval, the company's chief executive said on Wednesday.

CEO Jim Mullen said during an investor conference held in New York that the company has completed Phase 1 trials and will study dosing the drug once every two weeks as well as once monthly.

"I think we've got a good chance of similar efficacy as interferons," he said.

Patients in the trials will be treated for one year with the injectable drug and full results will likely be available in two years, Mullen added.

Avonex, with sales of $573 million in the third quarter of 2008, is the leading drug for multiple sclerosis, an autoimmune disease in which the body mistakenly attacks the fatty myelin coating surrounding nerve cells.

Biogen, along with marketing partner Elan Corp Plc (ELN.I: Quote, Profile, Research), also sells MS drug Tysabri, which was taken off the market after its 2004 introduction when it was linked to a potentially fatal brain infection, but reintroduced beginning in 2006 because there were so few good options for patients with MS.

Mullen said investors continue to underestimate the newer drug's sales potential: "We have a much more bullish view on Tysabri than the Street does."

"We've got a 40 share of the overall MS market, which could easily go to 50," the CEO said.

He said other discrepancies between Biogen's outlook and that of Wall Street include the company's "more bullish view on the sustainability of Avonex," growth potential for the franchise surrounding non-Hodgkin's lymphoma drug Rituxan, and additional opportunities for trimming costs.

Mullen said Biogen will no longer report new cases of progressive multifocal leukoencephalopathy, the brain infection associated with Tysabri, through filings with securities regulators, but will instead issue weekly updates on its Web site.

Immune Molecule Decreases Severity Of Multiple Sclerosis-like Disease In Mice





ScienceDaily (Jan. 4, 2009) — A group led by Dr. Cedric Raine at Albert Einstein College of Medicine have explored the expression of an immune molecule (CXCL1) that interacts with myelin-producing cells, finding that CXCL1 decreases the severity of disease in a mouse model of multiple sclerosis (MS).

The autoimmune disease multiple sclerosis (MS) attacks the central nervous system, resulting in demyelination of neurons. Myelin-producing cells in the central nervous system are severely depleted in lesions in patients with MS.

Myelin-producing cells express immune receptors and have been shown to respond to the immune molecule CXCL1, although the role of CXCL1 in MS has not been previously explored. Dr. Raine and colleagues examined the effects of CXCL1 specifically expressed in the nervous system in a mouse model of MS. They observed decreased severity of disease and more prominent remyelination in these mice. CXCL1, therefore, may play a neuroprotective role in CNS autoimmune demyelination.

In future studies, Dr. Raine's group plans to determine how CXCL1 mediates protection in MS. "Exploration of these pathways affords novel therapeutic avenues to enhance the limited remyelination typically seen in MS."
