Christopher Anzalone – President and CEO

Thanks, Vince. Good afternoon, everyone, and thank you for joining us today.

The 2014 fiscal year was one of progress and expansion for Arrowhead. We pushed our first candidate ARC-520 into the clinic. We began rapid pipeline expansion with the introduction of our next candidate ARC-AAT and we made important corporate progress on multiple fronts, such as strengthening our balance sheet.

Let’s begin with ARC-520.

We completed a first in man Phase 1 study in nine cohorts that assessed safety and tolerability of doses ranging from 0.01 to 4 mg/kg, in a total of 54 subjects. There were no dropouts for adverse events, no serious adverse events or adverse events rated as severe.

Neither the incidence nor severity of AEs was different between the treatment groups and placebo. And we did not see any dose limiting toxicities. ARC-520 and the underlying DPC delivery system appears to be well tolerated at all dose levels studied. This is a strong and important statement, a substantial unknown for any new candidate and platform entering clinical studies, as whether a safety signal will emerge that was not predicted in animal models. The positive safety profile we have seen represents a significant derisking event for ARC-520 and a broader DPC platform.

With confidence in the safety and tolerability of ARC-520, we moved into a Phase 2a dose finding study in order to characterize single dose activity in chronic HBV patients. Specifically, we are learning the safety profile of ARC-520 in HBV patients and how deeply various doses of ARC-520 will suppress a specific viral protein to surface antigen or s-antigen.

This study is ongoing but we have completed dosing 24 patients in three initial cohorts, 1, 2 and 3 mg/kg. We have presented data from 1 and 2 mg/kg and we are still following patients from the 3 mg/kg cohort which is still blinded. We have begun screening patients for enrollment in an additional cohort of 8 patients at 4 mg/kg.

Several important findings are emerging. First, the safety profile of ARC-520 appears to be similar in patients as in healthy volunteers. Second, ARC-520 is clearly active and decrease in production of s-antigen. And third, the duration effect is longer than we expected, which has very positive implications for upcoming multi dose Phase 2b studies. These are good data. As far as we know, this is the first reliable report demonstrating clear reduction of s-antigen in humans after its single dose.

As such and because many believe that decrease in s-antigen could lead to a functional cure of chronic HBV, physicians and HBV experts we spoke with at the recent AASLD liver meetings shared our excitement. We reported mean peak knockdown for 39% with 1 mg/kg of ARC-520 and 51% with 2 mg/kg.

Simply put, this has been a lofty and unmet goal in the HBV field for years, and we just accomplished it. With these preliminary data, let me tell you why we are so confident about the program. Our goal is not to clear s-antigen directly with ARC-520 but rather to decrease it to a level that derepresses immune system such as it may take over and control the virus. If successful, this is potentially allowed to functional cure because no drug has been able to do this consistently to precise level of reduction required to enable this process is unknown.
