In severe persistent hyperinsulinismHIrepeated hypoglycemic episodes can ultimately lead to permanent seizure disorderslearning disabilitiescerebral palsyblindness and even deathClinical studies have demonstrated the effectiveness of both short term and long term treatment with glucagon for severe forms of HI and continuous subcutaneous administration of glucagon has been recommended both because of the potential improvement in patient outcome and high costs of surgical intervention followed by long term annual care costsHoweverthe instability of glucagon in solution creates both administration problems and potential complications due to infusion tube blockageThese instability problems have limited the use of glucagon for severe persistent HITo overcome this problemin our successful Phase I grant we developed a series of solution stable glucagon analogs using a novel design approach and demonstrated their effectiveness both in vitro and in vivoThese analogs when formulated in a conventional sterile diluent maintain not only the standardpotency requirement throughout ayear storage period atC but more importantly offer an extendedin usestability period of at leastmonths atCSuch analogs are compatible with implementation in a pump system for the long term management of severe persistent HI without concern for complications due to glucagon instability and pump clogging issuesIn additionsuch a product will be suitable for emergency hypoglycemic incidences which result in overhospitalizations a yearFinallythe resultant product could be implemented in a bi hormonal artificial pancreas for Tand TdiabetesIn this Phase II projectwe aim to develop large scalegram levelGLP production of the lead candidatescomplete toxicologyimmunogenicity and formulation studiesand prepare a regulatory package suitable for filing an IND in preparation for clinical trials In our successful Phase I granta series of novel glucagon analogues were designedproduced at milligram levelstested for solution stability and for both in vitro and in vivo activityWe have identifiedlead candidates with superior physical properties and biological activity in vivo using a hyperinsulinism modelIn this Phase II proposal we aim to complete large scalegram levelGLP production of the lead candidatescomplete toxicology and formulation studiesand prepare a regulatory package suitable for filing an IND in preparation for clinical trials aimed to demonstrate the use of our stable glucagon analogs for treating congenital hyperinsulinismemergency hypoglycemia and ultimately for treating Tand Tdiabetics using a bi hormonal pump
