ImmuneRegen BioSciences Signs Lovelace Respiratory Research Institute as Development and Regulatory Partner

Lovelace Senior Scientific Advisor to Assist ImmuneRegen with Preclinical Studies and Clinical Trials for Homspera(TM)

Tuesday February 19, 6:30 am ET

SCOTTSDALE, Ariz.--(BUSINESS WIRE)--ImmuneRegen BioSciences, a wholly owned subsidiary of IR BioSciences Holdings, Inc. (OTCBB: IRBO - News), today announced it has finalized an agreement with Lovelace Respiratory Research Institute (LRRI) in Albuquerque, N.M., to provide a broad range of product development services pertaining to inhalation and intranasal drug delivery, and associated regulatory affairs support. This strategic relationship is expected to support ImmuneRegen’s preparation for an Investigational New Drug Application (IND) for Homspera™.

Lovelace is a private biomedical research institute with a broad range of research capabilities and research alliances that bear on respiratory health issues of concern to government, industry, university, and health advocacy organizations, as well as the public. Lovelace is committed to the cure of respiratory diseases through research aimed at understanding their causes and biological mechanisms, eliminating exposures to causal agents, and developing improved treatments. This focus parallels that of ImmuneRegen’s research and development activities for Homspera, making LRRI an ideal partner for ImmuneRegen’s development activities.

Efforts to be pursued at Lovelace will involve both the inhalational administration of Homspera, which was used in early radioprotection studies, as well as the intranasal administration used more recently in the studies demonstrating anti-viral activity, vaccine adjuvant activity, and hematologic stem cell. The inhalation work, in conjunction with the development of analytical tools supporting drug analysis and assessment in biological systems, will enable the pharmacokinetic studies of Homspera (which reveal the rate in which it enters and leaves the blood) following multiple modes of administration.

In addition, Lovelace’s research will support ImmuneRegen’s previous evaluations conducted for the National Institute of Health (NIH) to address the organization’s inquiries regarding potential Homspera treatment of radiation sickness, influenza, and SARS. Once addressed, the NIH is expecting to independently evaluate the efficacy of Radilex in preventing or treating radiation sickness in an animal model. NIAID will evaluate Radilex for possible activity as a medical countermeasure for application in a radiation/nuclear emergency, including a terrorist attack. These evaluations are funded as part of the NIH Radiation/ Nuclear Countermeasures Product Development Program. The goal of this program is to increase the U.S. government’s knowledge base, and support private sector product development surrounding potential medical countermeasures.

ImmuneRegen also announced that Chet Leach, Ph.D., previously Director of Preclinical Toxicology for Lovelace and Director of Life Science Research and Development at Nektar Therapeutics, will serve as an independent consultant to the company, assisting in planning upcoming clinical trials and non clinical studies, and helping to prepare for eventual clinical trials of Homspera. Leach has nearly 30 years experience in toxicology and pulmonary drug development, having also held positions at IIT Research Institute, Battelle Pacific Northwest Laboratories, and 3M Pharmaceuticals, where he was Head of Preclinical Pulmonary Drug Development.

Michael Wilhelm, president and chief executive officer of ImmuneRegen, said, “We are thrilled to work with Lovelace, a worldwide leader in research on the prevention, treatment, and cure of respiratory disease. Respiratory disease is a significant business opportunity for ImmuneRegen, and Lovelace’s expertise in this area will be a valuable asset to our scientific team. There is a great comfort knowing that such an exceptional assembly of experts will be assisting ImmuneRegen with our drug delivery work, IND advancements, and submission initiatives, as well as facilitating significant progress among our drug candidates development in areas such as H5N1 infection, stem cells, wound healing, cancer, etc.”

Wilhelm continued, “Dr. Chet Leach is an experienced consultant in drug development who has assisted over 20 biotechnology and pharmaceutical companies with a range of regulatory filings, and has a number of significant drug development efforts to his credit. We are confident that his input into our clinical trials and regulatory strategy will help to ensure our future success.”
