 favorable safety and tolerability profile. The first Phase 1 study was a double-blind, placebo-controlled, ascending, single-dose study in 20 healthy subjects. Participants received single intravenous doses of EB06, ranging from 0.1 to 20 mg/kg. No deaths or serious adverse events (“AEs”) were reported. EB06 was generally safe and well tolerated at doses up to 20 mg/kg. A second Phase 1 study evaluated the effect of single doses of EB06 to generate proof-of-principle data on the neutralization of CXCL10 in an inflammatory setting in humans using an experimentally nickel-induced allergic contact dermatitis model. For this double-blind, placebo-controlled study, 16 subjects were exposed to single intravenous doses of 180 and 720 mg of EB06. No deaths or serious AEs were reported, and EB06 was generally safe and well tolerated. A third, open-label, single-arm Phase 2 study investigating multiple administrations of EB06 in patients with primary biliary cirrhosis with an incomplete response to ursodeoxycholic acid (“UDCA”) was also completed. A total of 29 patients were treated with 10 mg/kg intravenous doses of EB06 every two weeks, for a total of 6 doses. No serious treatment-related AEs were reported. In addition, in a variety of pre-clinical in vitro and in vivo experiments, EB06 demonstrated the ability to neutralize the biological activity of CXCL10. In animal toxicology studies, EB06 was well-tolerated.

Allergic Contact Dermatitis

Contact dermatitis is a common occupational and work-related skin condition. The disease can be either irritant contact dermatitis or ACD. Based on market research, we believe that together these conditions cost up to $2 billion annually in the U.S. as a result of lost work, reduced productivity, medical care and disability payments. Based on the prevalence data of contact allergy in the general population, which we sourced from scientific literature and market reports, we estimate that there are as many as 30 million people in the seven major markets (US, UK, Germany, France, Spain, Italy, Japan) and Canada with ACD, and of these, we estimate that 40% have chronic exposure or frequent recurring exposure to a causative allergen. Based on the mechanism of action and topical delivery, we believe that the total addressable patient population for EB01 is as high as five million people in the seven major markets and Canada
