Abstract:
DESCRIPTION: (Investigator's abstract) Polynitroxyl hemoglobin (PNH) will be
developed as a neuroprotective oxygen carrier. PNH is different from 1st
generation hemoglobin-based oxygen carriers (HBOCs) in that it has added
anti-inflammatory activity in addition to oxygen carrier function. PNH is
created by covalently attached nitroxides, an analogue of nitric oxide (NO) in
a piperdine "cage," to HBOC. We have shown that PNH is an oxygen carrier with
anti-inflammatory superoxide dismutase and catalase mimetic activities. In the
Phase I of the present application, we propose to develop PNH as an
anti-inflammatory oxygen carrier and demonstrate that it is resistant to
oxidative damage in vitro and neuroprotective in vivo. In Phase II of this SBIR
application, we propose to elucidate the mechanisms and efficacy of PNH with a
hemodilution protocol in clinically relevant brain injury models. In a
companion Phase I/Il SBIR entitled "Polynitroxyl Hemoglobin (PNH) : Preclinical
Safety," we propose to conduct toxicology studies of PNH for an IND submission
to FDA.
PROPOSED COMMERCIAL APPLICATION:
An oxygen carrying resuscitative fluid with anit-inflammatory activities such as PNH is
highly desirable. HBOC products in advanced clinical development, provide only oxygen
delivery. Unfortunately, during severe hemorrhage, or trauma, there is significant inflammatory
(ischemia and reperfusion) injury. The inflammatory injury often lead to multiple organ failure
(MOF). Therefore the use of PNH is to provide better protection against MOF in trauma
resuscitation and can be used as a neuroprotective oxygen carrier in ischemic, hemorrhagic
and traumatic head injury. The market potential for a 2nd generation HBOC is established to
be 3 billion/year.
