Aldagen Acquired by Regenerative Biotherapy Firm Cytomedix

GAITHERSBURG, Md. – Cytomedix, Inc. (OTC/BB: CMXI), a leading developer of biologically active regenerative therapies for wound care,inflammation and angiogenesis, announces the completion of the acquisition of Aldagen, Inc., a privately held biopharmaceutical company developing regenerative cell therapiesbased on its proprietary ALDH bright cell (“ALDHbr”) technology. Under the terms of thetransaction as described below, Cytomedix issued preferred shares valued at $16 millionbased on a 10-day volume-weighted average price (“VWAP”) calculated through February 2,2012. Cytomedix will issue additional consideration to be paid in common stock upon the successful attainment of several clinical milestones. As part of the transaction, certain Aldagen investors purchased $5.0 million of Cytomedix common stock in a private placement concurrent with the closing of this acquisition.

Martin P. Rosendale, Chief Executive Officer of Cytomedix, commented, “Since joining Cytomedix as chief executive in 2008, our strategy has evolved, but the vision to transform the Company from a wound-care based technology platform into a broader regenerative medicine company has remained constant. In pursuit of this vision, we started with the successful 2010 acquisition and integration of the Angel System, a unique, best-in-class PRP platform technology that has allowed us to grow from nominal sales to $6 million per year injust over 18 months.”

“This strategic acquisition of Aldagen provides Cytomedix with a novel, patent-protected cell selection technology that fits well with our existing commercial products and strengthens our long-range growth profile”, he continued. “In combination, we now touch the three pillars of regenerative medicine with autologous stem cells, platelet-derived signal molecules and plasma scaffolds,” he added. “We view the acquisition of Aldagen as an opportunistic transaction at an attractive valuation that will allow us to build and expand our new product development efforts with Aldagen’s technology, intellectual property, people and clinical expertise. In terms of maximizing opportunity for our shareholders while managing and mitigating risk, we feel this transaction is very advantageous.”

Commenting on the acquisition, Richard Kent, M.D., Chairman of the Board of Aldagen and a Partner with Intersouth Partners, Aldagen’s largest shareholder, said, “We are delighted to join forces with Cytomedix as this alignment unites commercial products with a growing revenue stream with a deep pipeline of clinical opportunities. We believe these autologous technologies are complementary and hold potential to produce more therapeutics than either one could on its own. The commitment of additional capital into Cytomedix by certain Aldagen investors underscores our confidence in the very promising potential for the combination of these regenerative technologies to change how we treat a variety of large disease areas with continued unmet medical need.”

Transaction Terms

At the closing, Cytomedix issued 135,398 newly designated Cytomedix Series E preferred shares to Aldagen shareholders. Pro forma for the conversion of these shares to common stock, as set forth in the designations documents for the Series E preferred stock, Aldagen shareholders will own approximately 17.3% of Cytomedix common shares outstanding after the concurrent conversion and/or redemption of all existing Cytomedix preferred shares.

There are also contingent clinical milestone payments totaling up to 20,309,723 shares, which will be issued to Aldagen shareholders upon the achievement of predetermined clinical milestones associated with an ongoing Aldagen Phase 2 trial in post-acute ischemic stroke. Notably, 80% of this contingent consideration is issuable only upon a favorable clinical efficacy signal in the above-mentioned trial. The costs of the clinical trial will be funded, in part, by the $5.0 million investment made by Aldagen shareholders, $3.0 million in proceeds from completed or committed warrant exercises by existing Cytomedix shareholders, as well as a portion of Cytomedix’ cash on hand. All upfront and contingent consideration shares are subject to lockup restrictions ranging from six to 18 months.

As part of the transaction, as of the closing date three Aldagen Board members have joined the Cytomedix Board, which has been expanded to nine seats. They are Richard Kent, M.D., Chairman of the Board of Aldagen, Lyle Hohnke, Ph.D., Aldagen’s former CEO, and Joseph Del Guercio, Managing Director of CNF Investments and a current Board Observer for Aldagen. Concurrent with these additions, Craig Mendelsohn has stepped down from the Cytomedix Board.

In addition, Edward L. Field, Aldagen’s Chief Operating Officer, has been appointed as Chief Operating Officer of Cytomedix. Aldagen is now a wholly owned subsidiary of Cytomedix and will retain manufacturing and product development facilities in Durham, N.C. For additional information about this transaction, please refer to the Company’s Report on Form 8-K, filed with the Securities and Exchange Commission on or about February 8, 2012.

About Aldagen

Aldagen is a clinical-stage biopharmaceutical company developing patent-protected autologous cell-based therapeutics for tissue repair and regeneration. Aldagen’s clinical development efforts are led by a team of leading researchers and experienced clinicians. All product candidates target conditions with significant unmet medical needs. Aldagen has a deep product pipeline and data generated in a number of disease states including:

  • ALD-301 for the treatment of peripheral arterial disease (“PAD”) and critical limb ischemia (“CLI”)
  • ALD-201 for the treatment of ischemic heart failure
  • ALD-401 for the treatment of ischemic stroke

Safety has been demonstrated in more than 70 patient treatments across all clinical trials of ALDHbr cells and positive study results in CLI and cardiac ischemia have been published and presented at major medical meetings. A growing body of scientific data validates Aldagen’s proprietary technology, including approximately 250 peer-reviewed publications and presentations. Aldagen has the only stem cell selection technology utilizing an intracellular enzyme marker to fractionate essential regenerative cells from bone marrow.

Aldagen’s proprietary bone marrow fractionation process identifies and isolates metabolically active cells expressing high levels of the enzyme aldehyde dehydrogenase, or ALDH, which is a key enzyme involved in the regulation of gene activities associated with cell proliferation and differentiation. The selected biologically instructive cells, ALDHbr cells, have the potential to promote the repair and regeneration of multiple types of cells and tissues, including the growth of new blood vessels, which is critical to the generation of healthy tissue. Preclinical research suggests that ALDHbr cells specifically migrate to sites of ischemic damage and induce the formation of new blood vessels at those sites. In human clinical trials utilizing ALDHbr cells, evidence of improved perfusion in ischemic tissue has been observed. Other stem cell therapies require expansion of cells that increase manufacturing and regulatory risk, increase processing costs and may delay treatment of the patient up to several weeks. Aldagen produces well-characterized cell populations with a high level of purity without the need for these additional steps, thereby enabling a rapid turnaround time – typically 36 hours once the bone marrow is received.
