Medicinova's Ibudilast (MN-166): Possible Neuroprotection in Multiple Sclerosis?

March 22, 2010

Surprising Phase II Clinical Trial Results of Oral Ibudilast Show Some Evidence of Neuroprotection But Little Impact Against Inflammation in MS | www.nationalmssociety.org

Ibudilast is an antiphosphodiesterase inhibitor, with putative anti-inflammatory and neuroprotective CNS effects. Phase II results have been epublished on Neurology's website in a paper by Barkhof et al.There was no effect on the standard markers of disease, such as relapse rate and active lestions. However, some additional analyses suggest a possible neuroprotective effect. The big question is whether this will be confirmed in a larger trial. At this point, some skepticism should be exercised.

December 15, 2008

Novartis’s Multiple Sclerosis Drug Cuts Relapse Rates | www.bloomberg.com

FTY720 may be among the first and the most promising oral therapies to arrive on the scene for MS . On December 12, Novartis reported the initial results of the 1-year TRANSFORMS study in relapsing MS. Compared with Avonex, FTY720 reduced relapses by an additional 40-50%.

Will Alemtuzumab Be A Revolutionary Treatment For Multiple Sclerosis?

December 11, 2008

Study Results: Multiple Sclerosis Patients Have Significant and Sustained Reduction in Disability and Risk Of Relapse On Alemtuzumab Versus Approved Therapy, Rebif(R) | www.marketwatch.com

Out of a crowded field of new MS therapeutics in phase III study, alemtuzumab has clearly distinguished itself from the rest. Although not a cure, the efficacy is nothing short of jaw-dropping. Most MS therapeutics are pitted against placebo, with a 30-60% reduction in relapse rate compared to taking nothing at all. However, the CAMMS223 had an unconventional study design in that they used Rebif, a medication already established to be highly effective in MS, as their comparison arm. The implication is that a much higher bar of efficacy is required, often needing very large numbers of participants.  For a phase II trial with only a few hundred participants, this must have been a very controversial decision at the time.

Suspected PML Cases For Biogen, Elan MS Drug Not Alarming | www.djnewsplus.com

The next generation of MS therapeutics is beginning to emerge, and it appears to be a crowded field of contenders. To be determined over the next several years is how the standard agents will fit with the newer agents, what level of efficacy and/or convenience is needed to balance safety and risk, and how will these new medications fit together in clinical practice. The downturn in the market may present opportunities for the savvy investor.
