Thank you, Brian. We had a very productive first quarter with the launch of the Phase III REVIVE-CLI study of ixmyelocel-T, the report of new preclinical and clinical findings in support of ixmyelocel-T and the completion of the largest financing in our history.
Let me begin with an update on the Phase III REVIVE-CLI clinical trial, which is now underway. And as a reminder, the goal of this study is to confirm the benefits that we saw in the Phase II study, in the treatment of patients with critical limb ischemia, who have already experienced tissue loss and have no other treatment options. As we've told you before, there are 80, 8-0, 80 U.S. medical centers that we have qualified to participate in this important pivotal study, with others that are anxious to be included in the study, standing by. As we reported yesterday, we're very pleased to have now enrolled our first patient in this study, and this is an important milestone for Aastrom, and we feel very good about this early momentum in the Phase III REVIVE study. And we'll continue to work with our steering committee members and clinical investigators toward our enrollment target of 594 patients.
Now, as with most severe chronically ill patient populations, we expect that the pace of enrollment of these no-option CLI patients will initially be slow as we've seen. And this is the result of the sites developing and working the referral networks and prescreening patients. But with a very experienced, hard-working Aastrom clinical development and operations team, which you've heard me talk about before, combining efforts with a committed and enthusiastic group of steering committee and Eligibility Review Committee members, investigators and site coordinators, we're pretty confident that we're going to be successful in reaching our enrollment goals for the Phase III REVIVE-CLI clinical study.
The enthusiasm of everyone on the team stems from the groundbreaking results from our Phase IIb, RESTORE-CLI clinical trial, which represented by Dr. Bill Marston at the November 2012 American Heart Association Meeting and recently published by Dr. Rick Falwell in the peer review journal, Molecular Therapy.
I want to highlight, for everyone on the call today, but especially anyone who's new to the Aastrom story, what these results have demonstrated. The RESTORE-CLI Phase IIb clinical trial was a 12-month study and showed that treatment with ixmyelocel-T significantly reduced the risk of treatment failure by over 60%. That is, these no-option CLI patients treated with our therapy, ixmyelocel-T, had fewer events compared to the untreated or the control group. Equally important, and a potential predictor of our Phase III success, the trial showed, in a subgroup of patients with wounds at baseline, our Phase III patient population, a significant improvement in amputation-free survival, which is our Phase III primary end point, again by over 60%.
One other note of interest. The therapy was very well tolerated, with no difference in the rate of severe adverse events between the treated and the controlled groups, and both the AHA presentation and the Molecular Therapy publication reflect Aastrom's commitment to peer review of our work and to transparency in our data disclosure.
It was in this spirit that we attend the Keystone Symposia on Atherosclerosis in March to present data on the potential athero-protective effects of ixmyelocel-T due to the CD14 positive autofluorescence cells, or the so-called M2 or the anti-inflammatory macrophages, that are unique cells to our product. As we reported that the Keystone conference, these alternatively activated or M2 macrophages appear to have positive effects on atherosclerotic lesions through active removal of apoptotic cells and activating the reverse cholesterol transport pathway. Our continued research into the mechanism of action of our product, has found that the CD14 auto-positive cells are a unique cell population. These cells are found in significant quantities only in our autologous cell therapy product, ixmyelocel-T, and no other cell therapy product. CD14 auto-positive cells are not found in any allogeneic cell therapy products which are, as you probably know, CD90 or MSC cells, nor are the CD14 auto-positive cells found in cell therapy products derived from fresh bone marrow.
Needless to say, we're continuing to explore the biology of ixmyelocel-T and evaluate the activity and the potential benefits of this unique multicellular therapy.
Let's turn our attention now to the DCM program, which is also progressing well. And today, we reported the positive final results from our Phase IIa catheter study at the Society for Cardiovascular Angiography and Intervention's 2012 Scientific Sessions. Tim Henry, Dr. Tim Henry, the Director of Research, and an interventional cardiologist at the Minneapolis Heart Institute at Abbott Northwestern Hospital, and the study's principal investigator, presented these findings which show that ixmyelocel-T repaired damaged heart muscle and improved heart function in patients with ischemic DCM or progressive heart failure due to dilated cardiomyopathy. The treatment was well tolerated, and nicely improved symptoms in patients after 1 year, compared with those patients receiving the current standard of care. In the meantime, we've been planning and are prepared to initiate our Phase IIb clinical study of ixmyelocel-T in the treatment of ischemic DCM patients, which has been named Renew DCM [ph]. The Renew DCM Phase IIb clinical trial will be launched in June, enroll up to 100 DCM -- ischemic DCM patients at up to 15 sites across the U.S., and deliver the therapy in a single treatment of up to 20 IM injections via the NOGA MyoStar catheter. The patients in the study will be followed for 12 months with final results available in the first half of 2014.
Both the CLI and DCM programs have made great progress during the past year and we are now in a much stronger financial position to maintain this pace of progress thanks to our recently completed $40 million financing with Eastern Capital. This was the largest financing in Aastrom's history and was completed on very attractive terms. The preferred stock that we issued to Eastern will convert into common stock at a price of $3.25 a share and not until March 2017. So not only has their investment given us the capital to expedite our drug development work, especially the pivotal Phase III REVIVE-CLI clinical study, it has also allowed us to avoid the smaller much more expensive and dilutive financings to which other biotech companies have had to turn. As we noted in March, this financing was transformational for Aastrom and our shareholders. We were able to avoid having to issue warrants and we avoided issuing our stock at a significant discount. In fact, we issued the stock at a premium. We believe this was a compelling investment opportunity, not only for Aastrom and Eastern, but we thank Eastern, again, for their confidence in the Aastrom team.
Let me close with a brief comment on business development activity by reporting that we're continuing to speak with potential partners who seem -- continue to seem very interested in our work and impressed with our scientific and clinical progress. And as I said to many of you before, the timing of any agreement is impossible to predict. So I won't. But we remain very, very optimistic. In summary, we're off to a very productive start this year, with the resources and talents to advance our clinical programs, and move ixmyelocel-T toward commercialization.
So that concludes our prepared remarks. And we'd like Ben to open the call to your questions. Ben?
