Analyst · Safe Harbor Financial Management
Thanks, Michael. Good afternoon, everyone, and thank you for joining us on our call today. The first quarter of our 2012 fiscal year brought transformational change for Arrowhead. As I mentioned before, Arrowhead is now focused and operationally integrated Nanomedicine Company.
With the acquisition of Roche's RNAi assets and facility, we now have broad capabilities in small RNA therapeutics and a facility in Madison Wisconsin, where we are consolidating our R&D operations. While these initiatives have increased our cash burn, we still maintain a capital efficient structure and our ability to create value has increased dramatically. We believe that our portfolio of delivery options, our broad RNAi chemistry licenses and our state-of-the-art facilities and technical talent represent the most complete set of RNAi capabilities in the industry.
We are able to rapidly advance our own products and are positioned as an attractive partner for company's interested in RNAi therapeutics. In addition to these important advances within our RNAi programs, we also made great progress in our obesity program. In the quarter and more recently, we achieved 2 goals with the publication of non-human primate data that received widespread news coverage and clearance to initiate human clinical trials by the FDA.
Our recent major accomplishments include: one, acquiring Roche's RNAi assets and research facility; two, executing the collaboration and joining licensing agreement with Alnylam that allows Arrowhead to develop a DPC enabled RNAi therapeutic candidate targeting hepatitis B virus or HBV and allows Alnylam to utilize DPC delivery technology for one of their own RNAi therapeutic products.
Three, reporting preclinical results for Adipotide demonstrating substantial weight loss, reduction in body mass index and abdominal circumference in obese rhesus monkeys. These data were published in the journal, Science Translational Medicine and our partner MD Anderson has received clearance to initiate a Phase I trial in humans. Four, generating cash from financing activity and implementing a 1-for-10 Reverse Stock Split. And five, expanding the company's Management Team, Board of Directors and Scientific Advisory Board.
Previously, I have commented extensively on our October 2011 acquisition of Roche's RNAi Therapeutics Group, select licenses and state-of-the-art research facility in Madison, Wisconsin. Roche invested over $0.5 billion to acquire and develop the technologies necessary to independently create RNAi therapeutics. We now have the most comprehensive portfolio of nucleic acid delivery platforms including our proprietary RONDEL system, Dynamic Polyconjugates or DPCs and Liposomal Nanoparticle or LNPs.
We also have licenses to use the three primary RNAi chemistry formats; Canonical, Dicer substrate and Meroduplex. With world class technologies and a world class team, it is worth emphasizing that Arrowhead is now the most comprehensive RNAi therapeutics company in the world and well positioned as a partner of choice for large biotech and pharmaceutical companies interested in RNAi therapeutics.
We are well underway to complete the integration of our technologies and R&D activities in Madison. I would like to discuss some of our recent progress in greater depth. In November, primate data with our anti-obesity peptide, Adipotide was published in Science Translational Medicine. Adipotide specifically targets and kills blood vessels supplying white fat tissue and they're a significant interest in non-CNS therapy that has the potential to help obese patients.
The public data demonstrated weight loss, reduction in body mass index and abdominal circumference and marked improvements in insulin resistance in obese rhesus monkeys, after only 28 days of treatment. This was an important achievement as most anti-obesity drugs candidates have failed to translate rodent data into positive primate data.
We have made this transition and the data were striking. In January we announced that the Investigational New Drug Application or IND for Adipotide was accepted by the FDA, thereby providing clearance to initiate a Phase I clinical trial to test the safety of the compound in human patients. Our partner, MD Anderson Cancer Center in Houston plans to begin treating obese prostate cancer patients in the Phase I study in the coming weeks, and is bearing all of the direct costs associated with this trial.
Up to 39 patients are expected to take part in this Phase I trial; up to 5 dose levels of the drug will be tested. Re-participants will be enrolled at each dose level, with each group of participants receiving the lowest dose level by injection under the skin, once per day for 28 days, and each new group receiving higher dose than the group before it, if no intolerable side effects are seen.
This will continue into the highest tolerable doses found. Initiation of this trial will be a significant milestone for our rapidly advancing obesity program. We are very excited about the potential for Adipotide platform and believe we have a very powerful suite of drug candidates that not only may help combat obesity, but also may help to reverse symptoms associated with type II diabetes.
There are a number of reasons that the Phase I is enrolling obese prostate cancer patients, rather than focusing exclusively on obesity. One, prostate cancer patients, on long-term hormone therapy become obese over time due to chemical castration. Two, obesity complicates dosing regimes, so decreasing of patient's BMI could make ongoing cancer therapy simpler and more effective. Three, there is increasing data that some tumor types may become less aggressive, if fat load is decreased because fat acts as an endocrine organ.
Therefore in addition to increasing quality of life for prostate cancer patients, weight loss may be helpful in management of the disease. MD Anderson is a leader in prostate cancer treatment. So we expect it to be able to enroll patients rapidly.
If the Phase I is successful, and we establish a safe dosing schedule, we will have the ability to do one or multiple Phase II trials. These could include more prostate cancer patients and/or otherwise healthy obese patients and/or type II diabetes patients. The Phase I data will help us understand Adipotide safety profile and also help us choose an optimal patient population that can benefit from this therapy.
In January, we executed a collaboration and joint licensing agreement with Alnylam, allowing Arrowhead to develop the DPC enabled RNAi therapeutic candidate targeting hepatitis B virus or HBV and Alnylam to utilize DPC delivery technology for one of its own RNAi therapeutic products.
Both companies are eligible to receive milestone payments and royalties on sales by products resulting from their licenses. This deal is important to Arrowhead for several reasons. To license this technology to leading RNAi company like Alnylam so soon after we acquired the technology from Roche is a strong validation of the potential for the RNAi delivery assets that we acquired.
We licensed the DPC technology to Alnylam for a single product only, allowing us to demonstrate what our technology can do, without giving up much in terms of rights. As we work in close collaboration with Alnylam we are certainly open to further partnerships that would provide Alnylam with access to the DPCs for additional targets.
More importantly, in December I said I would provide more guidance on our first independent lead compound coming out of the DPC program after the first of the year. I'm pleased to say that the license we now have from Alnylam, we are now able to expand our pipeline to include our first DPC enabled RNAi therapeutic candidate targeting HBV.
With over 350 million carriers worldwide, HBV represents a large underserved medical need and one that RNAi and DPCs are well suited to address. We are very pleased with the preclinical data generated by Roche and are excited to be able to develop a proprietary DPC-enabled RNAi therapeutic targeting HBV.
Of course all this progress with our new RNAi platforms does not suggest that we are backing away from RONDEL and our first clinical candidate CALAA-01. To the contrary, we have a team in Madison that is focused on continual optimization of RONDEL and actively working to broaden its use. The CALAA-01 Phase Ib is treating patients and we expect this to be complete by summer.
With that update, I will now like to turn the call over to our CFO, Ken Myszkowski to review our financials for the period. Ken?
