The partnership will include an undetermined number of in vitro and in vivo studies on the potential wound healing effects of Homspera, to be underwritten by Uluru. ImmuneRegen and Uluru will consider entering into a license agreement to take any developed wound healing product to market. "We are proud to have entered into our first co-development partnership and look forward to a prosperous relationship with such a high quality company as Uluru," says ImmuneRegen CEO, Michael K. Wilhelm. "We are hopeful that this project will result in an ImmuneRegen-Uluru product that could deliver significant benefits to the user and to the medical community." Previous tests in small animals as well as supportive data from third- parties have revealed evidence leading management to believe that the use of Homspera could be effective in accelerating the wound healing process. Homspera has also shown efficacy in small animals at protecting against lethal radiation and microbiological attack (specifically influenza and anthrax spores), and has shown indications of being protective against specific inhaled noxious chemicals.
