Hollis-Eden Pharmaceuticals, Inc. is a world leader in the development of a proprietary class of adrenal steroid hormones as novel pharmaceuticals for human health. Through its Hormonal Signaling Technology Platform, Hollis-Eden is developing a new series of small molecule compounds that are metabolites or synthetic analogs of endogenous hormones derived by the adrenal glands from the body's most abundant circulating steroid. These androstene and androstane hormones, designed to restore the biological activity of cellular signaling pathways disrupted by disease and aging, have been demonstrated in humans to possess several properties with potential therapeutic benefit -- they regulate innate and adaptive immunity, reduce nonproductive inflammation and stimulate cell proliferation. The Company's lead product candidate, NEUMUNE[R] (HE2100), is entering late-stage development for the treatment of Acute Radiation Syndrome (ARS), a life-threatening condition resulting from exposure to high levels of radiation following a nuclear or radiological incident, and is being explored for use in combating healthcare-associated infections. Hollis-Eden also is profiling optimized second-generation compounds for potential clinical development in a broad spectrum of therapeutic categories including hematology, metabolic disorders, autoimmune disorders, pulmonary diseases, oncology and infectious diseases.
