About AEOL 10150

AEOL 10150 is a broad-spectrum catalytic antioxidant specifically designed to neutralize reactive oxygen and nitrogen species. The neutralization of these species reduces oxidative stress, inflammation, and subsequent tissue damage-signaling cascades resulting from radiation exposure. AEOL 10150 could have a profound beneficial impact on people who have been exposed, or are about to be exposed, to high-doses of radiation in the treatment of oncology.

AEOL 10150 has already performed well in preclinical and non-clinical studies, was well-tolerated in two human clinical trials, and has demonstrated statistically significant survival efficacy in an acute radiation-induced lung injury model. The Company believes it could have a profound beneficial impact on people who have been exposed, or are about to be exposed, to high-doses of radiation, whether from cancer therapy or a nuclear event.

About Aeolus Pharmaceuticals

Aeolus Pharmaceuticals is developing a new class of catalytic antioxidant compounds that protects healthy tissue from the damaging effects of radiation. Its first compound, AEOL 10150, is being developed for oncology indications, where it is used in combination with radiation therapy. It is also being developed, with funding by the US Government, as a medical countermeasure against chemical and radiological weapons, where its initial target indications are as a protective agent against the effects of acute radiation syndrome and delayed effects of acute radiation exposure. Aeolus' strategy is to leverage the substantial investment in toxicology, manufacturing, and preclinical and clinical studies made by US Government agencies in AEOL 10150, including the contract with BARDA valued, with options, at up to $118 million, to efficiently develop the compound for use in oncology.
