PRLog (Press Release) - Mar. 13, 2013 - NEW YORK -- Immune Response BioPharma, Inc. to Seek Orphan Designation of NeuroVax for Pediatric Multiple Sclerosis to Expand Use of Novel Vaccine Treatment.

Immune Response BioPharma, Inc. Today, Announces plans to seek Orphan Designation of Blockbuster Drug NeuroVax for a new indication of Pediatric Multiple Sclerosis. Pediatric MS effects approximately 10,000 children in the U.S.A. and NeuroVax is the first vaccine to be developed for this debilitating rare disease.

The FDA Office of Orphan Products Development (OOPD) mission is to advance the evaluation and development of products (drugs, biologics, devices, or medical foods) that demonstrate promise for the diagnosis and/or treatment of rare diseases or conditions.

Orphan Drug Designation carries multiple benefits, including the availability of grant money, certain tax credits and seven years of market exclusivity, as well as the possibility of an expedited regulatory process.

"NeuroVax is a first in class and best in class vaccine for multiple sclerosis, which helps to restore deficient FOXP3+ Tregs and treat the underlining causes of the disease. By seeking Orphan Designation for children with pediatric MS this will expand the use of NeuroVax & allow for a more speedy development of the drug. This also gives us a new indication to go after, as well it will give us further flexibility in trial design. Orphan designation for pediatric use of NeuroVax this will give IRBP and accelerated and expedited pathway to bring this important therapeutic vaccine for MS to market & treat this rare disease. We are also on track to secure a corporate partner for NeuroVax and move towards our Phase IIb study by years end, we should have some news on that front in coming months as partnering discussions continue with our valued potential partners" Mr. Buswell CEO IRBP.

About NeuroVax:

NeuroVax is a Once a Month Dosing injection, Safe, Tolerable, Enhances FOXP3+ Tregs & Regulates Pathogenic T Cells in MS Patients, a First in Class Disease Modifying Multiple Sclerosis Vaccine.

NeuroVax™ has been shown to stimulate strong, disease-specific cell-mediated immunity in nearly all treated patients. NeuroVax™ appears to work in part by enhancing levels of Foxp3+ Tregs, which may help regulate expression of pathogenic T cells in MS patients. The three TCRpeptides combined in NeuroVax™ correspond to one or more TCRgene families which are over expressed in 90% of MS patients. Previous clinical trials conducted by the Company and other independent researchers including a 27 patient clinical trial of NeuroVax have associated diminished levels of Foxp3+ Treg responses with the pathogenesis and progression of MS.This same mechanism appears to be important in the pathogenesis of other autoimmune diseases such as RA and psoriasis. Monthly vaccinations over one year with NeuroVax™ markedly expanded the capacity of regulatory T cells (Tregs) to recognize TCRs expressed by potentially pathogenic T cells. New data were also presented that showed NeuroVax™ produced a significant increase inTCR-specific T cells in patients with MS,including increases in interleukin-10-secreting T cells (IL-10) and Foxp3+ Tregs.
