Masitinib 'shows promise' in treating MS(27/07/15)
Progressive multiple sclerosis patients treated with AB Science’s lead compound AB07002 (masitinib) in a Phase III clinical trial showed positive results in a non futility test (a test to determine if an experimental therapy shows some sign of efficacy).
With the successful completion of the futility analysis, AB Science is set to continue the remainder of the double-blind, randomized, placebo-controlled study.
“We are very pleased with this outcome as our three on-going Phase III studies in neurology, in progressive forms of multiple sclerosis, in Alzheimer’s disease, and in amyotrophic lateral sclerosis, are all non futile,” stated Alain Moussy, CEO and co-founder of AB Science, in a news release from the company.
“This was not obvious since those three indications have remained so far a challenge for the pharmaceutical industry. This may be indicative of the potential of masitinib for the treatment of neurodegenerative disorders.”
In a futility analysis, a compound is tested in patients to see if it is unable to achieve the defined efficacy objectives of the study. If the compound is declared non futile, then the researchers conducting the trial can continue with the trial because there is reason to believe the compound will achieve its efficacy objectives. A medication to treat forms of progressive multiple sclerosis would be a huge win, as there are no on-label, clinically approved medications for progressive multiple sclerosis patients.
“This positive outcome of the futility test is good news because there is no registered treatment in this indication,” said Professor Ramió-Torrentà, a lead investigator in the trial at Dr. Josep Rueta University Hosptial in Spain.
“All drugs registered in relapsing forms of multiple sclerosis, recently or not, have failed so far to demonstrate efficacy in the progressive forms of multiple sclerosis. Furthermore, masitinib is not an immunosuppressive drug, unlike drugs used in relapsing forms of multiple sclerosis.”
In the 96-week trial, patients with primary progressive or relapse-free secondary progressive multiple sclerosis are being treated with masitinib, a selective tyrosine kinase inhibitor. The compound can control the survival, migration, and degranulation of mast cells by inhibiting key cell signaling pathways. This indirectly controls the amount of proinflammatory and vasoactive mediators release in the nervous system that contribute to disease characteristics.
After one third of patients enrolled for the trial were treated for a total of 48 weeks (halfway through the trial, with an intended full enrollment of 600 patients), they were assessed for changes in the Multiple Sclerosis Functional Composite (MSFC), Multiple Sclerosis Quality of Life 54 Items (MSQOL-54), and changes in the Expanded Disability Status Scale (EDSS). The observed changes were significant enough for masitinib to be declared non futile by the Independent Data Safety Monitoring Committee (IDMC). There were also no major or unexpected adverse events that affected the safety of patients, indicating that the Phase III clinical trial is justified to continue forward.

Nutra Pharma, a US-based biotechnology company specialising in the acquisition, licensing, and commercialisation of pharmaceutical products and technologies for the management of neurological disorders, cancer, autoimmune, and infectious diseases, has announced it has filed an application with the US Food and Drug Administration (FDA) for orphan drug status for its investigational drug RPI-78M as a treatment for paediatric multiple sclerosis (MS).
If the orphan drug designation is granted to RPI-78M, it would provide the company with a seven-year period of market exclusivity in the US upon receiving FDA approval.
The FDA Orphan Drug Designation program provides orphan status to drugs and biologics, which are defined as those intended for the safe and effective treatment, diagnosis or prevention of rare diseases/disorders that affect fewer than 200,000 people in the U.S., or that affect more than 200,000 persons but are not expected to recover the costs of developing and marketing a treatment drug.
In the US, it is easier to gain marketing approval for an orphan drug, and there may be other financial incentives, such as extended exclusivity periods intended to encourage the development of drugs, and the waiver of Prescription Drug User Fee Act (PDUFA) filing fees, which can offer savings of up to $2.5 million.
Nutra Pharma chairman and CEO Rik Deitsch said in a statement: “In May, we announced that we had engaged consultants to prepare several FDA applications for us as we start to re-engage our clinical platform. We have worked hard over the past year to restructure our Company, introduce a unique and effective OTC pet pain product, and now we are getting back to our roots as a biotechnology company. We have a broad product platform that consists of therapies for auto-immune diseases, viral diseases and neurological conditions.”
As for future goals of the company, Deitsch added: “Our goal now is to get our drug products through the approval process and into the market. It is very exciting that we are starting with this application that has the potential to help children suffering from MS.”
According to Nutra Pharma, venoms are an effective source of molecular tools that are able to improve the cell function understanding. The company also mentioned that the approval of some neurotoxins as human treatments has provided new opportunities for the treatment of MS.
RPI-78M induces gamma-interferon and interleukin-27 (IL-27). IL-27 is a recently discovered and important anti-inflammatory regulator in cells of the immune system. The drug was derived from a cobra venom extract and works as a nicotinic acetylcholine receptor antagonist. The drug has been found to have low toxicity with a very large therapeutic window. RPI-78M is to able Improve quality of life, reduces chronic fatigue, improve walking ability and strength.

A company that specialises in turning University research into marketable drugs is licensing Harvard research related to the blue evergreen hydrangea root, a part of the plant that has been used in traditional Chinese medicine for centuries.
Allied-Bristol Life Sciences, a joint venture between university commercialisation specialist Allied Minds and US pharmaceuticals giant Bristol-Myers Squibb, is licensing research carried out by Professor Malcolm Whitman and Dr Tracy Keller at Harvard from 2002 onwards.
The pair found that the active ingredient in blue evergreen hydrangea root, called halofuginone, can block a type of rogue T-cell and also identified how it blocks these cells.
T-cells are the part of the immune system that tackles viruses, but rogue T-cells attack healthy cells and can cause inflammation and damage. This occurs in autoimmune conditions such as multiple sclerosis, type 1 diabetes and lupus.
Allied-Bristol Life Sciences is hoping to use the Harvard research, based on a synthetic form of halofuginone, to develop drugs to treat these types of conditions.
Whitman and Keller’s findings were published in 2012 and reported on the effects of halofuginone on a mouse with a model of multiple sclerosis. But this is the first time a company has explicitly stated they want to make a drug based on the research.
Blue hydrangea root has been used for at least 2,000 years in Chinese medicine and its efficacy was first noticed in the 1940s in the West, according to Harvard Magazine’s report of Whitman and Keller’s research.
But until the Harvard pair studied the root nobody knew exactly how it worked, meaning it was impossible to replicate its effects in a drug.
Allied-Bristol Life Sciences CEO Satish Jindal said: “The work done by Whitman and Keller is a terrific example of a promising early-stage therapeutic application that has the potential to make a significant difference to patients.
“We are pleased to support this project through the next phase of drug discovery to identify a candidate for clinical development. This is a great example of the type of university research that ABLS looks for, where our expertise and experience can accelerate bringing new therapies to patients that need them.”
Dr Whitman said: “Our research is at the right stage for an infusion of resources and expertise to accelerate its progression. We look forward to seeing the development of lead compounds from our laboratories into novel therapeutics for the treatment of fibrotic disease, and potentially other indications.”

More positive data reported by MedDay(19/06/15)
MedDay, a biotechnology company focused on the treatment of nervous system disorders is reporting additional positive data from its pivotal Phase III clinical trial, MS-SPI, with MD1003, a highly-concentrated pharmaceutical grade biotin, in patients with progressive multiple sclerosis.
The data shows an improvement of the Clinical Global Impression of change observed after 12 months of treatment with MD1003 and confirms the positive results presented at the American Academy of Neurology in April 2015.
Frederic Sedel, Chief Executive Officer of MedDay, said: "We are pleased to announce further positive findings which confirm the promising MD1003 Phase III data announced earlier this year. MD1003 remains the only drug to date that has demonstrated an ability to decrease the rate of disease progression and improve a significant proportion of patients with progressive MS.
"A second phase III placebo-controlled trial is underway looking at the effect of MD1003 in MS patients with permanent visual loss following optic neuritis and we look forward to announcing data from this trial later this year and potentially investigating a drug filing thereafter."
The Clinical Global Impression of change is a seven point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention and rated as:
One - very much improved;
Two - much improved;
three - minimally improved;
Four - no change;
Five - minimally worse;
Six - much worse;
Seven - very much worse.
During the MS-SPI trial, the Clinical Global Impression of change has been assessed by the clinician (clinician global impression, CGI) as well as by the patient (subject global impression, SGI) after 12 months of treatment. Mean CGI and SGI scores assessed at month 12 were statistically significantly better in the intervention group compared with the placebo group.
These results confirm the previously reported data of MS-SPI where the primary endpoint was defined as the proportion of patients who improved either on EDSS or on timed 25-foot walk (TW25) at M9, with a confirmation of the improvement at 12 months (M12) was met.
The mean change of EDSS between M0 and M12 decreased in the MD1003 group compared to progression in the placebo group. In the MD1003 arm, only four per cent of patients treated with MD1003 exhibited EDSS progression at M9 confirmed at M12 vs 13 per cent in the placebo group (p=0.07), which equates to a 67 per cent decreased risk of progression in the active arm within the studied period.

A drug that could halt the progression of MS may soon be developed thanks to a discovery by a team at the CHUM Research Centre and the University of Montreal.
The researchers have identified a molecule called MCAM, and they have shown that blocking this molecule could delay the onset of the disease and significantly slow its progression. These encouraging results from in vitro tests in humans and in vivo tests in mice have been published in the Annals of Neurology. "We believe we have identified the first therapy that will impact the quality of life of people with MS by significantly reducing the disability and the disease's progression," said Dr. Alexandre Prat, lead author of the study, researcher at the CRCHUM, and professor in the Department of Neurosciences at the University of Montreal.
The brain is normally protected from attacks by the blood-brain barrier. The blood-brain barrier prevents immune cells - lymphocytes - from entering the central nervous system. In people with MS, there is often leakage. Two types of lymphocytes, CD4 and CD8, find a way to cross this protective barrier. They attack the brain by destroying the myelin sheath that protects neurons, resulting in decreased transmission of nerve impulses, and plaque formation.
In 2008, Dr. Prat's team identified a cell adhesion molecule, called MCAM (Melanoma Cell Adhesion Molecule), which plays a crucial role in dysregulation of the immune system observed in MS.
"Our studies have shown that MCAM is necessary for the migration of CD4 and CD8 across the blood-brain barrier. If we block the interaction of MCAM with the protein to which it normally binds, we decrease the disease's activity," he said.
Independently, the biotechnology company Prothena Corporation plc also discovered complementary data regarding MCAM, which led to an ongoing collaboration between the CRCHUM and Prothena.
"We observed a decrease of approximately 50 per cent of the condition in mice with experimental autoimmune encephalomyelitis (EAE), the most widely used animal model of MS. What is especially significant is that we can stop it from the first symptoms in addition to having an impact on its progression, which is a first," noted Prat.
MS develops in most patients in two phases. For 10 to 15 years, there are outbreaks of symptoms interspersed with remissions. Later, the diseases progresses and the disability worsens, leading to the use of a cane or wheelchair. Currently, none of the drugs available on the market affect progression.
Prothena has developed a potentially disease-modifying antibody, called PRX003, which is designed, to inhibit MCAM function and thus prevent migration of destructive lymphocytes into tissue. Prothena expects to initiate clinical trials of PRX003 in healthy volunteers by the end of June, and anticipates a study in patients with psoriasis in 2016. Beyond psoriasis, anti-MCAM antibodies may be useful for treating a variety of diseases, including progressive forms of multiple sclerosis.

A drug developed from the toxin of a sea anemone to treat conditions such as multiple sclerosis have shown promise in a phase 1 clinical trial, it has been reported.
The drug, dalazatide, is being developed by Kineta Inc, and works differently from drugs currently used to treat immune disorders. They suppress the entire immune system, which puts patients at risk for infections, while dalazatide blocks only the white blood cells that trigger many autoimmune diseases.
"The results of this trial indicate an important advance in developing next-generation treatments for autoimmune disease that specifically regulate the immune response without broad immune suppression," Dr. Shawn Iadonato, Kineta’s chief scientific officer, told the Wall Street Journal.
Phase 1 trials are designed to test a drug's safety and tolerability using various dosages. Tested on patients with psoriasis, the group were given either 30 mg or 60 milligrams of dalazatide or a placebo by injections twice a week for four weeks.
Even though phase 1 trials are designed to test a drug's safety and tolerability, patients who received dalazatide, especially those getting the higher dosage, showed improvements in their psoriasis that continued during the month after the drug was stopped. In contrast, those patients taking a placebo experienced no changes.
Kineta hopes to begin recruiting patients next year for a phase 2 trial which will specifically test the drug's effectiveness.
The development of dalazatide is part of an ongoing effort to create medicines, including painkillers, from nature. Researchers have found, for example, that certain kinds of spider venom block the pathway that sends signals of pain from the nerves to the brain in a way that is non-addictive.

MS drug breakthrough by French firm(27/04/15)
French biotechnology company MedDay has announced encouraging results for a multiple sclerosis drug trial, saying it decreased its progress and in some cases led to a “significant improvement” for patients.
“This is the first time a drug has been able to decrease the rate of disease progression in addition to improving a significant proportion of patients with progressive MS," said MedDay CEO Frederic Sedel in a statement.
The experimental drug MD1003 has undergone Phase III clinical trial, the last stage before filing for authorisation to market the drug in the treatment of primary and secondary progressive multiple sclerosis.
The results of the study, presented to the annual meeting of the American Academy of Neurology, were encouraging, said Professor Ayman Tourbah, the study's principal investigator.
“The rapid rate of recruitment into this multi-centre study illustrates the serious need for a well-tolerated drug by patients with primary and secondary progressive multiple sclerosis,” he added in the company's statement.
“The significant proportion of patients showing improvement at twelve months, coupled with the decrease in risk of disease progression demonstrated here, makes MD1003 a potentially important new therapy for patients and in the field of MS.”
The application process to license the drug will begin when all the test results are in, expected by the end of the year.

Drug succeeds in trial(17/04/15)
An experimental drug comprising of a high-dose formulation of the food additive biotin has successfully helped patients with primary and secondary progressive MS in a major clinical trial, its French maker claims.
Biotin, also known as vitamin H, is already an approved food additive but the pharmaceutical-grade dose used in biotech company MedDay's drug MD1003 is 300 mg a day, which is 10,000 times the recommended daily food intake.
MedDay said a Phase III study with MD1003 met its goal of improving disability scores in patients after nine months and one year of treatment, potentially paving the way for the medicine to reach the market next year.
If all goes to plan, MedDay's drug could reach the market ahead of rival products in development at other companies, including Biogen's BII033, which is currently in Phase II clinical testing.
Although biotin is not a newly invented chemical, MedDay has U.S. and European patents protecting the dose and its use for MS.

New drug could reverse MS damage(15/04/15)
A new experimental drug, anti-LINGO-1, has been found to repair myelin and so radically improving nerve signalling, reports The Daily Telegraph.
The scientists studied patients who had optic neuritis – damage of the optic nerve.
The results showed 53 per cent of people on the drug saw their nerve signalling restored to normal or nearly normal while on average most saw signalling between the retina and the brain improve by 41 per cent.
Although the subjects tested were not actually diagnosed with multiple sclerosis, scientists say the new results prove anti-LINGO-1 can repair myelin, and so could help people with MS.
"This study, for the first time, provides biological evidence of repair of damaged myelin in the human brain, and advances the field of neuro-reparative therapies," said study lead author Dr Diego Cadavid, of Biogen.
All patients involved in the trial were given the new drug or a placebo once every four weeks for a total of six doses.
Because optic neuritis only usually affects one eye, doctors evaluated the recovery of the optic nerve by comparing it with the normal healthy eye.
The scientists are now following up patients to find out of the signalling improvement will restored their vision.
"More studies are needed to evaluate whether these changes lead to clinical improvement," said Cadavid.
The drug works by targeting ‘Lingo-1’ a protein which stops nerve cells from developing further once the nervous system is fully formed.
By blocking that protein, the drug effectively tells the body to carry on growing the nerves, which repairs any damage.
Biogen chief medical officer Alfred Sandrock said “We believe the results are encouraging, as this is the first clinical trial to provide evidence of biological repair in the central nervous system by facilitating remyelination following an acute inflammatory injury”.

Phase 1 trial completed(01/04/15)
Vaccinex, Inc. has today announced the successful completion of a multicenter phase 1, randomized, double-blind, placebo-controlled, single ascending-dose safety and tolerability study in adult patients with multiple sclerosis.
According to reports, a total of 50 patients took part in the trial to determine the safety and tolerability of the drug currently known as VX15/2503, a monoclonal antibody discovered, characterised, and successfully tested by Vaccinex in preclinical models of multiple sclerosis and Huntington's disease.
VX15/2503 was found to be well tolerated at dose levels of up to 20 mg/kg with no reports of treatment-related serious adverse events.
No maximum tolerated dose (MTD) was determined and no dose-limiting toxicities (DLTs) were observed.
A phase 2 clinical trial of the VX15/2503 antibody in Huntington's Disease is planned to begin in the first half of 2015.

Could molecules prevent MS damage?(09/03/15)
Researchers at the Icahn School of Medicine at Mount Sinai have identified new compounds that could protect from multiple sclerosis-related damage, based on studies in mice with nervous system damage, mimicking MS. The study appeared in the journal Nature Neuroscience.
Jeffery Haines, PhD, a post-doctoral fellow at Mount Sinai and the study’s lead author commented, “The compounds identified in this study, when administered orally, both reduced the inflammation that is a hallmark of multiple sclerosis and protected against the nerve cell damage seen in mouse models of the disease. The multiple sclerosis drugs currently on the market and being tested elsewhere seek to reduce the immune attack on cells, but none target neurodegeneration nor do they work to restore nerve cell function. The findings of this new study represent an exciting step in the process of advancing new oral treatment options.”
A molecule called XPO1 (also called CRM1,) may be involved in multiple sclerosis as well as other diseases. The researchers decided to target this molecule.
They tested whether drugs designed to block XPO1/CRM1 could stop MS in mouse models. Two drugs were identified, KPT-276 and KPT-350, that acted on XPO1/CRM1. The medications seemed to protect cells from what is called free-radical damage — the production of damaging ions faster than the body can remove them. Free radical damage may be one way that the nervous system is affected in MS. Not only did the medications block free radical damage, they also prevented inflammation by stopping cells involved in inflammation from dividing. Immune cells can cause inflammation, which may be positive in infection, but is damaging in MS in which the immune cells attack the body’s own myelin. Stopping immune cells in the case of MS is therefore positive.
The medications helped the mice, which lost movement due to an experimental treatment that damaged myelin, to regain some movement as well.
Patrizia Casaccia, MD, PhD, Professor of Neuroscience, Genetics and Genomic Sciences at Mount Sinai and senior author of the study noted, “The study results elucidate the molecular mechanisms underlying disease progression in multiple sclerosis models, providing a basis for future clinical trials to determine safety and efficacy of these chemical agents in humans with demyelinating disorders.”

A team of scientists have uncovered a molecule that fights one of the main causes of inflammatory diseases and could be the key to improved treatments for diseases like Alzheimer's, arthritis and multiple sclerosis. The research team, led by Trinity and the University of Queensland Australia, showed the molecule, MCC950, could suppress the key activator in inflammatory diseases, NLRP3. The finding also confirms that inflammatory diseases all share a common process, even though the part of the body becoming inflamed might differ.
Researcher Luke O'Neill said drugs like aspirin or steroids can work in several diseases, but can have side effects or be ineffective, and what they have found is a potentially transformative medicine, which targets what appears to be the common disease-causing process in a myriad of inflammatory diseases. There is huge interest in NLRP3, both among medical researchers and pharmaceutical companies, and they feel their work makes a significant contribution to the efforts to find new medicines to limit it. MCC950 can be administered orally and will be cheaper to produce than current protein-based treatments, which are given daily, weekly, or monthly by injection.
More importantly, the new molecule also remains in the body for a shorter duration, allowing clinicians to stop the anti-inflammatory action of the drug if the patient ever needed to switch their immune response back to 100 percent, in order to clear an infection. So far, the results have shown great promise for blocking multiple sclerosis in a model of the disease, as well as in sepsis where, in response to bacteria, potentially fatal blood poisoning occurs. However, the target for MCC950 is strongly implicated in diseases such as Alzheimer's disease, atherosclerosis, gout, Parkinson's disease and rheumatoid arthritis, which means it has the potential to treat all of these conditions. The study is published in medical journal Nature Medicine.

Alkermes plc has reported positive top-line data from a phase I study on its experimental MS drug, ALKS 8700. ALKS 8700 is a novel monomethyl fumarate (MMF) molecule being developed for the treatment of MS.
The three-part, randomized, double-blind phase I study was conducted to evaluate the safety, tolerability and pharmacokinetics (PK) of several oral formulations of ALKS 8700 as compared to both placebo and active control groups in 104 healthy volunteers.
Data from the phase 1 study revealed that ALKS 8700 provided MMF exposures with less variability and improved gastrointestinal (GI) tolerability when compared to Tecfidera. Patients reported lower GI-related adverse events when treated with ALKS 8700 (8.3 per cent) as compared to Tecfidera (41.7 per cent). Moreover, the candidate was also found to be well tolerated during the course of the study.
Encouraged by the positive results from the phase I study, Alkermes plans to conduct a meeting with the FDA and move a twice-daily dose of ALKS 8700 into a pivotal development program this year.

Drug development company Rock Creek Pharmaceuticals has announced a new clinical trial application with the Medicines Healthcare Products Regulatory Agency (MHRA) has been approved. The company is set to proceed with a Phase I study of Anatabine Citrate, a chemical that is found naturally in aubergine, potatoes, green tomatoes and other members of the Solanaceae family of plants, as well as in tobacco and tobacco smoke. The chemical is known for its anti-inflammatory properties unique from other anti-inflammatory drugs on the market, and may benefit patients with multiple sclerosis (MS).
The Phase I study will evaluate Anatabine’s pharmacokinetic profile in the form of modified release formulation prototypes, and its safety and tolerability profiles in healthy volunteers. The first two parts will involve an open-label, non-controlled, single-dose study on 14 healthy participants, using six formula variations, with each administered dose spaced 7-14 days apart. The variations will be distinct in dose and duration of therapeutic action. This will allow the company to determine which formulation is most ideal, based on safety. The third and last part of the Phase I study will be a double-blind, placebo-controlled, seven-day multiple dose study of the identified optimal formulation in healthy subjects.
“We are delighted to have been granted regulatory approval to begin our Phase I studies in the UK. This is the first clinical phase for our lead drug and will focus on safety and tolerability of six different formulations, five of which have modified release profiles and are of different doses. We look forward to generating our first human clinical data under this CTA,” said Rock Creek Pharmaceuticals CEO Dr Michael Mullan.
Rock Creek’s UK-based partner, Quotient Clinical, is set to begin enrollment of healthy subjects this month. While the company expects the study to stretch well into August, they expect to have a significant amount of research findings by mid-2015. Rock Creek also announced Quotient Clinical will be utilizing its RapidFACT® (Rapid Formulation development And Clinical Testing) service to hasten the development of these novel, oral, modified release formulations that have been co-developed between the two companies.

Acorda Therapeutics has today announced safety and tolerability data from a Phase 1 clinical trial of rHIgM22, a remyelinating antibody being studied for the treatment of multiple sclerosis. The trial, which followed participants for up to six months after receiving a single dose of rHIgM22, found no dose-limiting toxicities at any of the five dose levels studied. Based on this, the Company intends to advance clinical development of rHIgM22.
“We’re encouraged by the outcome of this trial, which showed that rHIgM22 was well-tolerated at all of the dose levels we studied,” said Anthony Caggiano, M.D., Ph.D., Acorda’s Senior Vice President of Research and Development. “We are currently developing the protocol for our next Phase 1 clinical trial of rHIgM22. The data from this study will help inform the design of the next trial, which will enroll people with MS who are experiencing an active relapse.”
This was a multi-center, double-blind, randomized, placebo-controlled study designed to evaluate safety, tolerability, pharmacokinetics, and immunogenicity of a single dose of rHIgM22 in participants with any type of MS who were clinically stable for at least three months. All participants remained on their existing MS treatment regimens, including disease-modifying therapies.
The first part of the study included five cohorts, with each cohort receiving a higher dose of rHIgM22 than the previous one. Each cohort consisted of 10 participants (eight receiving drug, two receiving placebo), who were followed for three months after receiving a single dose of study medication. In the second part of the study, 21 participants were randomized to receive placebo or one of the two highest doses of rHIgM22 from the first part of the study. These participants were followed for six months to assess safety and tolerability. The second part of the study also included several exploratory clinical, imaging and biomarker measures, which are still being analysed. The study was not powered to determine statistical significance on these measures.
Additional details from the trial will be presented at future medical meetings.
Across all of the study groups, 55 participants received one of the five doses of rHIgM22 and 17 received placebo (no sample size power calculation was used to determine the number of participants in each group). There were no dose-limiting toxicities and no serious adverse events (SAE) in any of the five rHIgM22 dose levels in the study. There was one SAE of squamous cell carcinoma in a placebo-treated participant.
The most commonly observed adverse events (>5 per cent in the combined rHIgM22 treatment groups) reported in the study were: headache, contact dermatitis, MS relapse, infusion site hematoma, fatigue, arthralgia, back pain, muscular weakness, neck pain, pain in an extremity, pruritus, contusion, and flushing. No participants withdrew due to adverse events.
No safety signals were identified by standard clinical MRI evaluations, or standard clinical, laboratory or ECG assessments.
rHIgM22 is a recombinant human monoclonal antibody identified in the laboratory of Moses Rodriguez, M.D. at Mayo Clinic. In preclinical studies, rHIgM22 has been found to protect oligodendrocytes and stimulate them to repair areas of demyelination. rHIgM22 treatment also resulted in sustained improvements in motor activity in preclinical models.

MedDay, a biotechnology company that develops new drugs for nervous system disorders, announced an update on the progress of its development pipeline with its lead product MD1003 for the treatment of primary and secondary progressive multiple sclerosis (MS). The first study is expected to be complete in early 2015, while the second should be complete in late 2015.
The company aims to develop drugs for neurological and psychiatric diseases through brain metabolism and is currently developing a compound to target progressive MS, the ultra-orphan condition adrenoleukodystrophy (AMN), Alzheimer’s disease, and autism.
MedDay’s MD1003 for MS, which have been approved for patent protection in the US and Europe, is a highly concentrated formulation of D biotin (vitamin H), a key co-factor for enzymes involved in energy production and synthesis of myelin. The company announced that trials for drug use for the treatment of primary and secondary progressive multiple sclerosis, continue to progress well.
A pilot open label study that enrolled 23 patients with primary and primary and secondary progressive MS confirmed the efficacy of MD1003. The trial is expected to enroll the last patient this month, and results should be presented on 18 April 2015 during the American Academy of Neurology annual meeting. Furthermore, the company has two-phase 2b/3, placebo-controlled pivotal studies in progress at 21 MS centers in France and in the UK where 250 patients are enrolled.
MedDay’s second trial in MS patients with permanent visual loss after optic neuritis, called “MS-ON’, is expected to retrieve results during the second semester of 2015.
In a recent press release, Frédéric Sedel, Chief Executive Officer of MedDay said, “MedDay is making rapid progress in demonstrating the clinical viability of its unique approach to the development of treatments that target the nervous system’s metabolism. This approach and our expertise come from the study of rare inborn metabolic errors. We anticipate the completion of our first pivotal trial in primary and progressive MS, an area in which currently available MS treatments have little or no effect, later this month and we are on track to complete a second study this year.”
Moreover, in order to develop additional pipeline assests, the company developed a research platform called SPECMET in collaboration with Assistance Publique Hôpitaux de Paris (APHP) and the Commissariat à l’Energie Atomique et aux Energies Alternatives (CEA). SPECMET aims to identify new treatment targets through cerebrospinal fluid metabolomics analyses.
“Our metabolomics platform, SPECMET, continues to identify specific metabolic signatures in major central nervous system disorders, providing numerous opportunities for further pipeline developments. By focusing on compounds that already have known activity in neurological metabolic pathways, we believe we can quickly demonstrate clinical proof of concept.”, Sedel said in the press release.

Arena Pharmaceuticals, Inc. released the first results from its phase 1b trial that for the evaluation of an oral drug candidate called APD334 for the treatment of autoimmune diseases, such as multiple sclerosis (MS). The multiple ascending dose clinical trial demonstrated encouraging findings about the drug, which is designed to target the sphingosine 1-phosphate subtype 1 (S1P1) receptor.
The scientists analyzing the drug observed a dose-dependent effect on lymphocyte count lowering in blood, with mean decreases from baseline of up to 69%, due to APD334, within the phase 1b, as announced by the company in a press release. On average, lymphocyte was registered as recovered to baseline a week after the conclusion of dosing.
“Lymphocyte lowering at the level demonstrated in this trial has been shown to correlate with clinical efficacy in Phase 2 and Phase 3 trials of other S1P1 modulators in multiple sclerosis, psoriasis and ulcerative colitis,” explained the Senior Vice President and Chief Medical Officer of Arena, William R. Shanahan, M.D. “The results of this trial support investigation of the efficacy and safety of APD334 in patients with autoimmune diseases.
In addition, no significant safety findings worth noting regarding heart rate or rhythm, pulmonary function, or elevations in liver enzymes were registered. The adverse events related to the treatment most commonly noted were mild or moderate contact dermatitis, headache, constipation and diarrhea, despite the fact that none of them were clearly attributed to the drug, and there were no discontinuations for adverse events nor serious adverse events observed.
The purpose of the randomized, double-blind, placebo-controlled phase 1b clinical trial was to assess the safety, tolerability, pharmacodynamics and pharmacokinetics of multiple-ascending doses of APD334. The study was conducted in five different dosing cohorts, which comprised a total of 50 healthy participants, who were administrated with APD334, as well as 10 other who received placebo during a 21-day period.
“Based on these impressive results, we plan to expedite APD334 into Phase 2 clinical trials for ulcerative colitis and Crohn’s disease,” stated Jack Lief, Arena’s President and Chief Executive Officer. “The advancement of this promising drug candidate further demonstrates Arena’s focused expertise in discovering and developing innovative drug candidates targeting G protein-coupled receptors that have the potential to improve health,” he added.

MedDay has provided an update on the progress of its lead product MD1003 for the treatment of primary and secondary progressive multiple sclerosis (MS), which is expected to complete its first pivotal study in Q1 2015. A second pivotal study is on track for completion by the end of 2015.
Development of MedDay’s lead candidate, MD1003, for the treatment of primary and secondary progressive multiple sclerosis, continues to progress well. Progressive MS is an area of significant unmet need. MD1003 is a highly concentrated formulation of D biotin (vitamin H). Patents protecting the dose and use in multiple sclerosis (MS) as an active pharmaceutical ingredient have been approved in the US and Europe, offering protection until 2032. Biotin is a key co-factor for enzymes involved in energy production and synthesis of myelin.
Proof of concept has been obtained in a pilot open label study involving 23 subjects with primary and secondary progressive MS. Two phase 2b/3, placebo-controlled, pivotal studies are ongoing, involving 250 patients and 21 MS reference centers in France and the UK. The placebo-controlled phase of the first registration trial MS-SPI is almost complete. The last patient visit is expected in mid-January 2015 and we aim to present the results at the American Academy of Neurology annual meeting on 18 April 2015.
Results of the second registration trial in MS, “MS-ON”, dedicated to patients with permanent visual loss following optic neuritis, are expected in H2 2015.

Biogen Idec Inc’s experimental drug for multiple sclerosis showed signs that it could help repair nerve damage in patients’ eyes, a tentatively positive step for a drug aimed at reversing progression of the disease.
In a mid-stage trial of 82 patients, Biogen’s drug showed a 34 percent improvement in those who completed the study. The result fell a hair below the threshold for statistical significance. Including patients who didn’t complete the study, results were positive but didn’t reach statistical significance, Biogen said today in a statement.
Biogen climbed 2.2 percent to $361 in early trading. The company, based in Cambridge, Massachusetts, gets most of its revenue from multiple sclerosis drugs like Tecfidera and is pushing for new treatments for the disease, which affects 2.3 million people worldwide. There are no approved cures for multiple sclerosis, only drugs that help suppress the immune system or manage symptoms.
“This is a huge hope,” said Tim Coetzee, chief research officer at the National Multiple Sclerosis Society, in a telephone interview before Biogen’s news was released. “Rebuilding the nervous system is the next frontier of how we tackle treating MS, and for many people who live with MS, strategies like this are a source of hope that they could get some function back.”
Multiple sclerosis causes the immune system to attack myelin, a fatty substance that coats and protects nerve fibres. Patients can experience tingling, problems with walking and degrading vision. Their symptoms get worse as MS progresses.
Biogen’s drug, called BIIB033, targets a protein in the the central nervous system that regulates myelin production. The antibody could spur the myelin to regrow and reverse the progression of the disease.
Biogen’s mid-stage trial tested the drug’s effects on optic neuritis, inflammation of the optic nerve often caused by multiple sclerosis. Interpreting the data may not be clear cut, according to Eric Schmidt, an analyst at Cowen & Co.
“Optic neuritis is really just a ‘proof of biology’ indication for MS,” he said in an e-mail before Biogen’s announcement today. “We really don’t know how data from one indication will translate to the other.” More studies that directly measure its effects on multiple sclerosis are needed before any conclusions can be drawn, Schmidt said.
While patients in the trial generally tolerated the drug well, two patients had hypersensitivity reactions around the time the drug was infused, and one had an elevation in enzymes that can cause liver damage, which resolved itself when the patient stopped using the medicine.

Switzerland-based GeNeuro has partnered with France-based Servier to develop and market GNbAC1 in Multiple Sclerosis (MS).
GNbAC1 is said to be the first drug being developed to address a causal factor of the disease, and holds the potential to radically change the way MS patients are treated.
A humanized monoclonal antibody, GNbAC1 targets the envelope protein of MS associated retrovirus, MSRV-Env, a member of the HERV-W family, the expression of which is usually silent but reactivated and expressed in MS lesions from an early stage in the disease.
GeNeur CEO François Curtin said: "This strategic agreement with Servier is a recognition of the innovative nature and huge potential of GeNeuro's technology.
"Combining GeNeuro's technical expertise with Servier's scientific, medical and financial resources will create an exciting new alliance to fuel the development of our unique approach, ultimately benefitting MS patients around the world."
As per terms of the agreement, GeNeuro will be responsible for the development of GNbAC1 until completion of Phase IIb, after which Servier can exercise the option to license the product for all markets excluding the USA and Japan.
Servier will pay around $47m to GeNeuro to complete the Phase IIb trail.
The company will cover the costs of the Phase III global development program and pay GeNeuro up to $408m in future development and sales milestones, as well as royalties on future sales, subsequent to exercising the option agreement.
According to Servier, GNbAC1 successfully completed Phase IIa trial, demonstrating an optimal safety profile and encouraging signs of efficacy on a first small cohort of patients.

Researchers identify chemical compound that decreases effects of multiple sclerosis Multiple sclerosis (MS), an autoimmune disease of the brain and spinal cord, affects about 2.5 million people worldwide (400,000 in the United States). Affecting more women than men, it can be seen at any age, although it is most commonly diagnosed between the ages of 20 and 40.
An unpredictable disease that disrupts the flow of information within the brain and between the brain and the body, MS is triggered when the immune system attacks the myelin sheath, the protective covering around the axons of nerve fibers. The "demyelination" that follows causes a disruption of nerve impulses. As the protective sheath - best imagined as the insulating material around an electrical wire - wears off, the nerve signals slow down or stop, and the patient's vision, sensation and use of limbs get impaired. Permanent paralysis can result when the nerve fibers are completely damaged by the disease.
Given such debilitating effects, an aggressive search is on among scientists to find a cure for MS. Currently available therapies are only partially effective, however, in preventing the onset of permanent disability in MS patients. What would be immensely helpful is a drug that could minimize the degeneration of axons, thus reducing the rate and degree of MS progression. Better still would be if this drug could stimulate "remyelination," the re-sheathing of the axons, restoring fast and uninterrupted flow of nerve impulses.
Now a team of researchers, led by a biomedical scientist at the University of California, Riverside, reports in this week's issue of the Proceedings of the National Academy of Sciences that it has identified just such a drug in the lab: indazole chloride (Ind-Cl).
"This drug, which we administered on transgenic mice, can potentially halt the symptoms and reverse ongoing motor deficit due to MS," said Seema K. Tiwari-Woodruff, an associate professor in the UC Riverside School of Medicine whose lab led the study. "Our study shows that Ind-Cl can remyelinate axons which have gotten injured not just in MS but also traumatic brain injury and spinal cord injury."
Tiwari-Woodruff explained that Ind-Cl is a chemical compound that stimulates an estrogen receptor, ERβ, in the body. As is well known, pregnant women with MS get near-complete relief from MS symptoms in their third trimesters. Estrogen levels, which are high at this time, have neuroprotective benefits, alleviating the MS symptoms. After the birth of the baby, estrogen levels plummet in the mother and the MS symptoms return.
"This readily suggests that estrogen could be given to MS patients, except that high levels of estrogen are linked to breast and uterine cancers," said Tiwari-Woodruff, who joined UCR earlier this year. "Further, men would largely be reluctant to take estrogen due to its feminizing effects." Enter Ind-Cl, a small compound Tiwari-Woodruff has worked with for about two years. This structurally unique ligand turns on the body's estrogen receptors without the negative effects of excessive estrogen.
"More encouraging is that this compound works after disease onset," Tiwari-Woodruff said. "This makes it promising because a patient with MS typically first visits the doctor when he or she has noticed some motor deficits - loss of balance, inability to pick up an object, an impairment in vision. By this time though, the axons responsible for these motor functions have been massively affected. But if a drug can be administered at this point that can help the patient gain some relief from the disease and further damage, we'd be on to something.
"Ind-Cl is just such a drug in that it inhibits selective inflammation of the central nervous system," Tiwari-Woodruff added. "Our work on mice suggests that its effect is permanent. But perhaps more significant, Ind-Cl remyelinates, that is, it makes new sheaths around those axons that have not been lost for good. This means Ind-Cl not only inhibits inflammation but is capable of reducing axon degeneration and restoring neuronal function."
Tiwari-Woodruff's lab conducted electrophysiology tests to ensure that the remyelinated axons were retransmitting impulses. According to her, Ind-Cl can be developed for oral administration. To ensure that the remyelination her team observed in the MS mice was due to Ind-Cl and not to an immune response, the team administered Ind-Cl in mice whose oligodendrocytes, the cells responsible for remyelinating axons and myelin, were selectively decreased.
"We found that remyelination occurred more efficiently in such mice after they were given Ind-Cl," Tiwari-Woodruff said. "This means Ind-Cl works in two ways: through the immune system in terms of reducing brain and spinal cord inflammation, and directly by remyelinating the axons. This makes it an extremely promising drug."
Tiwari-Woodruff noted that Ind-Cl can be tweaked to make analogs that could work even better at alleviating MS symptoms. Her colleague John A. Katzenellenbogen, an organic chemist at the University of Illinois at Urbana-Champaign (UIUC) and a coauthor on the research paper, developed Ind-Cl. In addition, his group has already identified four analogs that the research team will soon test on MS mice.
"We expect some of these analogs will soon go to clinical trial," Tiwari-Woodruff said.

ENDECE Neural announced the presentation of new, pre-clinical evidence that the company’s lead compound, NDC-1308, induces remyelination and increases forelimb grip strength in a validated animal model of demyelination. As presented in a poster session at the 2014 annual meeting of the Society for Neuroscience in Washington, D.C., the improvements with NDC-1308 therapy are linked to the drug’s unique ability to repair the myelin sheath of demyelinated axons (nerve fibres).
The data, presented by Steven H. Nye, Ph.D., Vice President of Discovery at ENDECE Neural, suggest that the remyelinating properties of NDC-1308 may benefit patients with secondary progressive multiple sclerosis (SPMS). ENDECE Neural has announced plans to initiate non-clinical investigational new drug (IND)-enabling studies of NDC-1308 and a first-in-humans Phase 1 clinical trial in 2015.
“We continue to be encouraged by the reproducible pre-clinical data generated for NDC-1308,” said Dr. Nye. “In addition to our previous knowledge about its mechanism of action, we now conclusively demonstrate the ability of NDC-1308 to repair the damaged myelin sheath in a cuprizone mouse model of demyelination. The grip-strength findings are especially encouraging, as this test may be translated to the clinic for measuring functional improvement in MS patients. We look forward to initiating clinical trials of this promising compound.”
Dr. Nye and colleagues reported that NDC-1308 induced significant remyelination in several brain regions using the cuprizone model of demyelination, in which the neurotoxicant cuprizone was used to remove the myelin sheath from the axons of mice. In addition, prophylactic treatment with NDC-1308 delayed the onset of clinical symptoms of MS in an experimental autoimmune encephalomyelitis (EAE) mouse model of brain inflammation while preserving neuronal cells, suggesting that it also exerts a neuroprotective activity. Chronic treatment with NDC-1308 was well-tolerated by the studied animals, suggesting it can be safely administered.
“All research to date indicates that NDC-1308 is ready to advance to IND-enabling and clinical studies,” commented James G. Yarger, Ph.D., Chief Executive Officer of ENDECE Neural. “The IND-enabling program has been designed to determine the safety and toxicity of NDC-1308 and appropriate starting doses for initiating Phase 1 studies in humans. We look forward to continuing the momentum from the pre-clinical studies as we enter the clinic with NDC-1308.”
NDC-1308 is a novel chemical entity designed to address the damage to the myelin sheath that occurs in patients with secondary progressive MS (SPMS), a common later phase of the disease that follows relapsing-remitting MS (RRMS). NDC-1308 is being developed for potential use either alone or in combination with other MS therapeutics that slow the progression of the disease. By dramatically up-regulating key genes in pathways leading to oligodendrocyte progenitor cell (OPC) differentiation and myelin synthesis, NDC-1308 appears to induce restoration of the lost myelin sheath that is believed to cause the devastating symptoms of MS. NDC-1308 is a small molecule that readily crosses the blood-brain barrier, allowing it to reach the tissues in the brain and spinal cord where promoting myelin production is needed. NDC-1308 works by inducing differentiation of OPCs into mature oligodendrocytes, cells that synthesize and maintain the myelin sheath. ENDECE Neural discovered NDC-1308, and owns the intellectual property surrounding the compound.

Genzyme, a Sanofi company, announced today enrollment of the first patient in a multicenter Phase II clinical trial to evaluate Genzyme’s investigational infusion therapy vatelizumab in patients with relapsing remitting multiple sclerosis (RRMS). The trial, called EMPIRE, is designed to assess the efficacy of vatelizumab vs. placebo in RRMS patients. The safety, tolerability and pharmacokinetics of vatelizumab will also be assessed.
Multiple sclerosis is a chronic inflammatory demyelinating and neurodegenerative disease of the central nervous system (CNS). Uncontrolled inflammation within the CNS leads to inflammatory damage that is associated with demyelinating lesions and neurodegeneration in patients with MS. Vatelizumab is a humanized monoclonal antibody that targets VLA-2, a collagen-binding integrin expressed on activated lymphocytes. The mechanism of action of vatelizumab is not known, although it is hypothesized to block VLA-2 on activated immune cells, leading to interference with collagen-binding in areas of inflammation, and thus may reduce the inflammatory cascade in MS.
“Continuous inflammation and neurodegeneration from the onset of multiple sclerosis can lead to significant disability,” said Eva Havrdova, MD, PhD, MS Center, Department of Neurology, First Medical Faculty, Charles University, Prague. “The EMPIRE trial should enable us to assess vatelizumab’s ability to impact the acute inflammatory components of MS and evaluate its potential as an effective MS treatment.”
Genzyme is developing vatelizumab in MS in partnership with Glenmark Pharmaceuticals. In addition to its marketed therapies, Genzyme has an MS R&D pipeline focused on investigational treatments to address unmet needs for relapsing and progressive forms of MS through research in selective immunomodulation, neuroprotection and remyelination.
“We are pleased to commence patient enrollment for our vatelizumab trial in relapsing MS,” said David Meeker, President and CEO, Genzyme. “This milestone demonstrates Genzyme’s long-term commitment to MS and aligns with our pipeline strategy to focus on areas of unmet need.”
EMPIRE is a global phase 2a/2b double-blind, randomized, placebo-controlled study assessing the efficacy, safety and dose-response of vatelizumab in patients with active RRMS. The study duration is 12 weeks. The study is expected to enroll 168 patients at 55 sites in 10 countries. For more information about the vatelizumab trial, visit www.clinicaltrials.gov.

Concert Pharmaceuticals Inc. announced Phase 1 data of CTP-354, a novel, potentially first-in-class, non-sedating, once-daily oral treatment for spasticity. In this multiple ascending dose trial, no sedation or ataxia was observed with CTP-354 and the drug was generally well tolerated across all dose cohorts.
Concert expects to initiate a Phase 2 clinical trial evaluating CTP-354 in patients with spasticity associated with spinal cord injury by the end of 2014.
"We are very pleased to have completed our clinical evaluation of CTP-354 in this Phase 1 trial. We remain on track to advance the program into Phase 2 testing later this year, initially targeting spasticity in patients with spinal cord injury followed by the start of a Phase 2 trial in multiple sclerosis patients in early 2015," said Roger Tung, President and Chief Executive Officer.
The Phase 1 multiple ascending dose clinical trial was a randomized, double-blind, placebo-controlled study in 30 healthy volunteers. The primary objective of the trial was to evaluate the safety, tolerability and pharmacokinetics of 10-day repeat dosing of 2 mg, 6 mg and 12 mg of CTP-354.
Clinical highlights include: CTP-354 was generally well tolerated. There were no serious adverse events and no treatment discontinuations. The most common adverse events were dose-related mild and moderate dizziness and somnolence (drowsiness). No sedation or ataxia was observed at the doses evaluated. Across all doses, plasma half-life was approximately 20 hours at steady state. CTP-354 exposure was generally dose-proportional across daily doses ranging from 2 mg to 12 mg. Administration of CTP-354 under both fed and fasted conditions provided similar exposure, indicating that it can be dosed without regard to meals.
The company previously reported positive results from both a Phase 1 single ascending dose trial and a Phase 1 brain imaging trial as measured by positron emission tomography, or PET imaging. The long half-life and pharmacokinetic profile observed in the single ascending dose support once-daily dosing of CTP-354. In addition, CTP-354 provided high and sustained brain GABAA receptor occupancy levels in the brain imaging trial in both single and repeat doses.
Based on the results of the Phase 1 trials, Concert intends to advance CTP-354 into Phase 2 clinical evaluation later this year. The Phase 2 program is projected to include two trials: one evaluating spasticity associated with spinal cord injury and one evaluating spasticity associated with multiple sclerosis.

San Francisco Bay Area-based Glialogix, Inc., a biopharmaceutical company that specializes in developing novel treatments for multiple sclerosis (MS), announced yesterday that they have closed a Sponsored Research Agreement with Fast Forward, a non-profit organization that aims to accelerate MS treatment development. Glialogix will receive funding for one of their pipeline products for neuroprotection, GLX1112, which has shown efficacy in slowing disability progression and potentially repairing neuronal damage — one of the main priorities of the National Multiple Sclerosis Society (NMSS).
Fast Forward, founded by the NMSS, will be supporting Glialogix through cutting-edge pharmacokinetic testing, preclinical models and mechanistic research on GLX1112. According to Thad Reeder, Ph.D., the company’s CSO and lead researcher for the drug, it has already shown promising results in progressive forms of MS.
Glialogix CEO, Mark Moore, Ph.D., explained that there is a great need for effective treatments for progressive MS, as this type tends to cause the most disability and does not respond to treatments indicated for relapsing MS. At present, while there are several drugs being tested for treating progressive forms of MS, most patients are treated with RRMS therapies, as these are the only drugs approved by the FDA for treating progressive MS in the United States. In other countries, progressive MS patients often have no access to therapies, and are forced to cope with symptoms and disabilities on their own.
Dr. Moore concluded by stating that he looks forward to collaborating with Fast Forward on the development of a viable progressive MS therapy, and is confident this new agreement is the boost GLX1112 is waiting for.

GeNeuro SA announced today positive results from a one-year, open-label extension of a Phase IIa study. GeNeuro tested its monoclonal antibody GNbAC1 in 10 multiple sclerosis (MS) patients, nine of which had primary or secondary progressive disease. GNbAC1 targets the MSRV-Env protein expressed by genes of endogenous retroviral origin, which GeNeuro believe plays a critical role in the pathogenesis of MS.
The long-term safety profile of GNbAC1 was confirmed, with excellent tolerability among patients following repeat administration, verifying results of the earlier Phase I study. With respect to clinical endpoints, the average Expanded Disability Status Score (EDSS), which measures disease progression, remained stable over one year. MRI analysis revealed that the brain images also remained stable and biomarkers associated with the target showed a consistent decline. These results confirm the safety and tolerability of GNbAC1 and support a positive pharmacodynamic response to the treatment. The positive results of this clinical study represent the successful first step in GeNeuro’s Phase II program. A proof-of-concept clinical study to test the efficacy of GNbAC1 in MS will follow in 2015.
Francois Curtin, CEO of GeNeuro stated: “We are very excited by the potential that GNbAC1 offers as a new avenue to treat MS patients. In addition to confirmation of long-term safety of the monoclonal antibody in patients, we have seen that the cohort of progressive MS patients was stable over one year from both clinical and MRI standpoints. Moreover, there is a clear decrease in the associated biomarkers supporting a positive pharmacodynamic response. This reinforces our conviction that GNbAC1 can completely transform the MS therapeutic landscape.” Curtin adds: “Preliminary results of this study presented at the American Academy of Neurology earlier this year generated a high level of enthusiasm among clinicians as they see that this treatment could bring new hope to patients as a safe therapy addressing a causal factor of the disease, breaking with the immunosuppressive logic of existing treatments.”
