Historical Stock Chart

XenoPort, Inc. (Nasdaq: XNPT) announced today that it was awarded U.S.
Patent 8,148,414 for â€śProdrugs of Methyl Hydrogen Fumarate,
Pharmaceutical Compositions Thereof, and Methods of Use.â€ť The term of
the patent extends until 2029, subject to potential Hatch-Waxman patent
The patent is directed to the XP23829 compound, analogs thereof and
formulations thereof. A related U.S. patent application directed to
therapeutic uses of XP23829 is now pending.
XP23829 is a prodrug of methyl hydrogen fumarate, also known as
monomethyl fumarate (MMF). In cell- and animal-based models, MMF has
been shown to exhibit immuno-modulatory properties and inhibit damage
from oxidative stress.
In XenoPortâ€™s preclinical animal studies that compared molar equivalent
doses of XP23829 to dimethyl fumarate (DMF), another prodrug of MMF,
XP23829 demonstrated a greater degree of efficacy in animal models of
both multiple sclerosis (MS) and psoriasis. Toxicology studies conducted
in two species showed that XP23829 caused less stomach irritation
compared to DMF.
XenoPort intends to file an Investigational New Drug Application (IND)
for XP23829 for the treatment of relapsing remitting MS with the U.S.
Food and Drug Administration (FDA) in the second quarter of 2012 and
expects to initiate human clinical trials later this year.
XenoPort owns all rights to XP23829.
