NJ -- Provid Pharmaceuticals receives NIH grant to fund multiple
sclerosis research
Provid Pharmaceuticals Inc. has been awarded an SBIR grant from the National
Institute of Neurological Diseases and Stroke (NINDS) to fund proof-of-concept
biological studies of the company’s lead molecules for multiple sclerosis.
One of the features of MS (and other autoimmune diseases) is that the disease
has a strong genetic correlation to MHC class II molecules. In MS patients,
the MHC class II molecule, HLA-DR2 is thought to bind peptide fragments of
the myelin nerve sheath that insulates neurons in the central nervous system.
In MS, the myelin peptide-MHC DR2 complex interacts with autoreactive T cells,
triggering the immune response that leads to destruction of the nerve sheath
and to the symptoms of the disease.
Provid has developed compounds that bind tightly to MHC DR2 and prevent antigen
binding. These leads will be optimized for binding affinity, pharmacokinetics,
and efficacy in inhibiting T cell activation. The cellular tests will
be using methodology developed by CTL laboratories and pursued in collaboration
with Case Western Reserve University (Drs. Thomas Forsthuber and Paul Lehmann).
The Case group also has developed an animal model using DR2 transgenic mice
that can be used to predict the inhibition of DR2-antigen presentation in
vivo.
The MHC inhibition approach developed by Provid has potential applicability
to many autoimmune disease targets, including multiple sclerosis, celiac
disease, rheumatoid arthritis, Graves disease, and type 1 diabetes.
The company is applying its expertise and proprietary methodology of peptide
mimetics to design and develop these compounds. Prior to the award
of the SBIR grant, Provid developed the lead molecules using a combination
of structure-based drug design and peptide mimetics methodology. The
program has been partnered with Suntory Pharmaceuticals Research Laboratories,
a subsidiary of Daiichi Pharmaceuticals for downstream development, marketing
and sales.
Provid is a chemistry-based drug discovery company with expertise in all
aspects of medicinal chemistry, structure-based drug design, lead optimization,
protein biochemistry and assay development. In addition to its autoimmune
disease platform for drug discovery, the company offers collaborative discovery
services to biotech companies and academic groups that need medicinal chemistry
expertise to transform their biologically driven research into drug molecules.
