Thanks, Michael. Good afternoon, everyone, and thank you for joining us on our call today. Arrowhead made substantial progress on multiple fronts during the second quarter of our 2012 fiscal year and soon thereafter.
We made progress in our existing programs, we made moves that maximize the value of our platforms, and we expanded our assets and capabilities in the manner that strengthens our core programs and provides new business opportunities. These are important value drivers.
Our recent major accomplishments include the following. One, received FDA clearance to initiative Adipotide Phase I clinical trial.
Two, executed a collaboration and joint licensing agreement with Alnylam, a leading RNAi therapeutics company which allows Arrowhead to develop a Dynamic Polyconjugate or DPC enabled RNAi therapeutic candidate targeting hepatitis B virus or HBV, and allows Alnylam to utilize DPC delivery technology for one RNAi therapeutic product.
Three, received a patent from the U.S. Patent and Trademark Office covering siRNA Inhibitors of HIF-2a, a target treating renal cell carcinoma.
Four, entered into a strategic alliance and master services agreement for RNAi therapeutics with Axolabs GmbH, a custom research organization offering preclinical solutions and consultancy in the field of oligonucleotide therapeutics.
Five, released the white paper on HBV and potential RNAi treatment, including Arrowhead DPC enabled RNAi therapeutic and development.
And sixth, acquired Alvos Therapeutics formerly known as Mercator Therapeutics Incorporated, a pioneering in targeting for tumors and tumor vascular cell in humans, including what we believe is the world largest proprietary library of human-derived targeting peptides.
Each accomplishment makes Arrowhead a stronger company and drives long-term value for our shareholders. As such, let’s consider some of them more closely.
In January, the IND for our obesity drug candidate Adipotide was accepted by the FDA allowing the initiation of a clinical trial that has the safety of the compound. Adipotide is a new class of treatment for obesity, design to specifically kill blood vessels supplying white fat tissue.
This is the first and what we believe to be powerful suite of drug candidates that not only may help to combat obesity, but may also help to reverse symptoms associated with Type 2 diabetes. The Phase I clinical trial will be conducted by The University of Texas MD Anderson Cancer Center which will bear all the direct costs associated with this trial.
This is an important platform for us, because of the powerful animal data that have been generated across multiple species, the unique mode of action and the enormity of the health problem.
In fact in analysis of the obesity epidemic in the United States was presented just yesterday at the Centers for Disease Control and Prevention, and published online in the American Journal of Preventive Medicine. It predicts that by the year 2030 42% of Americans will be obese.
These numbers are staggering because it means 32 million more obese people within 2 decades and this is on top of the almost 78 million people who were reportedly obese in 2010.
This is not a cosmetic problem but rather represents a public health cliff from which we cannot fall without incurring crippling economic and social costs. Obesity is potentially the largest pharmaceutical market in the industrialized world and we believe that our technology puts Arrowhead at the leading edge.
Also in January, we executed a collaboration and joint licensing agreement with Alnylam. As part of that agreement, we licensed to Alnylam, the use of our DPC to deliver siRNA against a single target. This includes active collaboration to ensure that the DPC and siRNA chemistries are optimized for this target.
These collaborations have begun and they represent an important step for us to become a partner to additional companies in RNAi therapeutics. We believe these partnerships suggest validation for the DPC platform, particularly because we were able to execute it only 2 short months after acquiring the DPC technology.
In addition, we are confident that this has a potential to lead to a larger partnership with Alnylam, as its scientists learn more about the broad power of DPC-enabled delivery.
The other side of the Alnylam deal provided us with a license to develop and commercialize in RNAi therapeutic, targeting HBV, the DPC-enabled RNAi therapeutic candidate targeting HBV was one of the more advanced RNAi programs at Roche and we have continued this work.
We now have a large data set that includes impressive results with multiple sequences across multiple animal models. This will be our first DPC-enabled candidate in the clinic. We have completed work, validating the specific type of DPC, siRNA sequences and chemical modifications we will use. This data will be presented over the coming months and weeks at scientific conferences and will be submitted for publication.
We plan to file an IND late in the second calendar quarter of 2013, the white paper we published which is available on our website, describes the substantial unmet need for 350 million HBV carriers worldwide and how RNAi and DPCs in particular are well suited to address the deficiencies of current treatment options. There is currently no cure for HBV and our treatment goal is to provide that cure rather than offering chronic treatments.
We are exploring the potential to conduct this trial in Asia, where we believe, we may be able to conduct the Phase 1 in HBV infected volunteers. Such a trial would be designed to generate an efficacy readout during Phase I, enabling relatively early partnering opportunities for these candidates.
Hepatitis B candidates have created a huge amount of value for many biotech and pharmaceutical companies recently, and we believe that HBV represents a similar but less crowded market that can grow a substantial interest. We are well-positioned to benefit from this interest.
Part of the final development of the siRNA chemistry used in our HBV candidate was done with Axolabs as part of our strategic alliance. Axolab's core team and facilities were part of Roche in Germany and before that they were the world’s first RNAi company. This team has helped to round out our capabilities and we believe that will make our partnering value proposition even stronger.
Under Roche, the DPC technology was largely embargoed from publicity. We are committed to publishing some of these data to unveil the power and flexibility of this platform.
We are currently preparing and submitting multiple reports to high impact peer-reviewed journals and expect publications this year. In addition, Arrowhead scientists will present DPC enabled siRNA delivery data including our RNAi therapeutic for HBV at 6 scientific conferences in May and June alone.
We are excited about these presentation opportunities at conferences around the world, which showcase years of efforts by our scientists to bring DPC-enabled therapeutics to market.
Our first clinical candidate using RONDEL delivery system, CALAA-01 is currently being studied in humans in the Phase Ib trial that we expect to be complete in early summer.
We continued to be pleased with what this has taught us about the RONDEL system. We still have not seen any SAEs that we believe are attributable to the delivery platform. This coupled with the clinical data we reported in the journal Nature 2 years ago, demonstrating mRNA and protein knockdown in biopsy tumors, as well as dose-dependent accumulation of our nano particles in tumor cells give us comfort that RONDEL is a powerful solution to systemic delivery of small RNAs.
Finally, we announced last month our acquisition of Alvos Therapeutics, formerly known as Mercator Therapeutics. Alvos has licensed a large platform of proprietary human-derived homing peptides from MD Anderson Cancer Center that we believe should be the world’s largest human-derived targeting library.
This technology is designed to direct therapeutic agents to primary and metastatic tumors, and associated vasculature, and then shuttle those agents directly into targets cells. The platform is powerful because of its breadth and how it was derived.
Regarding latter, MD Anderson employed phage display technology in end-stage cancer patients to identify peptides sequences that will bind and be rapidly taken up by specific cell types.
To our knowledge, only MD Anderson has been able to screen patients -- human patients in this way. The result is a library of approximately 42,000 sequences that will bind specifically to certain cell types. This should be immediately relevant therapeutically because they were derived from human patients rather than animal models.
While the goal was to produce sequences that could be conjugated to cancer drugs, in order to deliver those drugs preferentially to cancer cells, the library has substantial value beyond oncology as well.
In fact, we have sequences that will specifically bind virtually any tissue in the body, enabling us to target a wide variety of drugs to their preferred destination and nowhere else. As large and broad as this is, we also have the opportunity to work with MD Anderson to screen additional patients to grow the library further.
This acquisition strengthens our RNAi program because it is highly synergistic. We intend to apply the Alvos technology for targeting our proprietary siRNA delivery vehicles. Remember that our 2 primary siRNA delivery systems, DPCs and RONDEL are highly valuable in part because they are targetable.
We now have a huge proprietary library of targeting peptides for linking 2 of these vehicles, providing our program with a powerful new source of flexibility and value in oncology and beyond, where we use the library to create our own targeted RNAi therapeutics and we believe that this will be attractive to partners as well.
The new library is also valuable in creating a new class of therapeutics, peptide-drug conjugates or PDCs. We see this as a significant new value driver and new source of non-dilutive capital.
Our model with this program is to create new proprietary drugs by linking our homing peptides to generic drugs. This is designed to create “super generics” that have the advantage of years of clinical data, but are now targeted to accumulate preferentially at specific cells, while being invisible to other cells.
These holds the promise of decrease in side effect and toxicities, while increasing efficacy. Our program is also focused on working with partners to target their drugs and thereby enhancing their efficacy and limiting side effects.
This could be used to rescue failed compounds that may have been discontinued due to unacceptable off target effects. It could also be used as a powerful patent extension strategy by helping partners create advanced new drugs with those that are about to lose patent protection. Even though, they would be using existing APIs, these would be transformational new drugs that are actively guided to target cells.
We are very excited by this business and believe we will have substantial traction with large pharmaceutical companies, most of which are facing a steep patent cliff. The Alvos acquisition also serves to unify our programs. We are truly a targeted therapeutics company now.
We are leveraging a collection of RNAi platforms, much of which was assembled by Roche for over $500 million to create targeted RNAi therapeutics. We are also using or targeting platform to create targeted non-RNA drugs and Adipotide is our first clinical candidate.
With that update, I’d now like to turn the call over to our CFO, Ken Myszkowski, to review our financials for the period. Ken.
