GAITHERSBURG, MD--(Marketwired - Jan 6, 2014) - Cytomedix, Inc. (OTCQX: CMXI), a leading developer of biologically active regenerative therapies, announced today the completed enrollment of the RECOVER-Stroke trial. Based on an interim resizing analysis that was performed on the existing population of all subjects who have reached the treatment plus 90 days primary efficacy endpoint, it was concluded that the ongoing RECOVER-Stroke trial is adequately powered based on pre-specified assumptions at the current enrollment of 48 patients. Consequently, additional screening and enrollment of new patient subjects will cease immediately. The Company expects to announce the top line clinical results in May 2014 when they become available.
The RECOVER-Stroke trial is a double-blind, multi-center, placebo-controlled trial designed to assess the safety and efficacy of ALD-401 in patients with unilateral, cerebral ischemic stroke. The Company, in regular review of blinded data, noted that the pooled standard deviation of the primary efficacy endpoint measurement was substantially lower than assumed in the initial power analysis. Following the Company's review with its expert advisors, a formal, blinded interim resizing was performed. This analysis determined that the trial is approximately 90% powered to demonstrate the clinically appropriate difference in the primary efficacy endpoint, if any such difference exists. Importantly, there were no changes made to the assumed treatment effect variable in the resizing calculation and, therefore, no inferences about clinical efficacy can or should be made from this analysis before the May 2014 expected top line clinical result data availability.
Consistent with the Company's previous announcement, as the trial is considered fully enrolled at this point, the ongoing financial obligation to the study is substantially reduced as previously anticipated. Going forward, any additional cash expenditures associated with outside clinical expenses will be eliminated, and internal costs incurred to support the clinical operations for the trial will wind down while the remaining clinical data is being collected for reporting. As a result, clinical expenses will be reduced to the minimum required to meet the 12 month patient follow up requirements.
Martin Rosendale, Chief Executive Officer of Cytomedix, commented, "This is good news for Cytomedix shareholders. We will now release top line efficacy data from an appropriately powered Phase 2 trial for a significant market opportunity in May and the reduction in the number of subjects required to complete the study will result in direct savings of approximately $2.5 million in outside clinical trial costs. It is important to emphasize that the result of the resizing analysis does not provide any indication of treatment effect, and the clinical outcome is currently unknown. While no inferences can or should be drawn at this juncture, in the event of a positive clinical outcome, there may be several substantial value enhancements that would accrue to the clinical program as a consequence of the smaller sample size, the less than expected standard deviation and the resulting improved statistical power to detect a clinically meaningful difference between treatment groups. In addition, the investigation of ALDH bright cells in ischemic stroke patients has not resulted in any significant safety issues to date. We will continue to work closely with clinical sites on monitoring visits and associated trial activities and look forward to reporting top line data in May 2014, as currently anticipated. We will also continue to investigate all potential options for maximizing the value of the underlying bright cell technology. Finally, the streamlined Durham, NC research and development facility will continue to support the clinical study manufacturing requirements of the ongoing National Heart, Lung, and Blood Institute (NHLBI) sponsored Phase 2 PACE study in peripheral arterial disease. Because NHLBI is responsible for all PACE clinical study costs, we consider the incremental costs of the manufacturing support manageable over the interim period while we wait for clinical data on the stroke program."
"The successful enrollment of this important, first of its kind trial has required the collaborative efforts of many people," noted James Hinson, M.D., Cytomedix's Chief Medical Officer. "We are grateful to our investigators, their teams, and the clinical and manufacturing staff that have supported this study. Most importantly, we are indebted to the subjects who volunteered their time and expressed trust in the investigators and our product."
About ALDH Bright Cells
ALDH Bright Cells are a population of autologous stem cells isolated from the patient's bone marrow using Cytomedix's proprietary Bright Cell technology. These adult stem cells express high levels of the intracellular enzyme aldehyde dehydrogenase (ALDH), an indicator of biological activity in heterogeneous early stage stem cells. Preclinical research suggests that ALDH Bright Cells may promote the repair of ischemic tissue damage by producing signaling molecules that are involved in cell homing, angiogenesis and neurogenesis. ALD-401 has shown improvements in motor function, in mitigation of the decrease in brain volume, the reversal of decline in stroke-induced cell viability, and improved blood flow in the brain in ischemic stroke animal models.
The RECOVER Stroke Trial is a double-blind, multi-center, placebo-controlled trial designed to assess the safety and efficacy of ALD-401 to improve clinical outcomes in patients with unilateral, cerebral ischemic stroke with an NIH (National Institute of Health) stroke scale score of less than 22 when administered between 13 and 19 days post the ischemic event. The primary endpoint of the study is safety and the primary efficacy endpoint is neural function based on the modified Rankin Scale assessed at three months following treatment. Strokes remain one of the leading causes of long-term disability. With the majority of strokes occurring in patients 65 years and older, it is also a major financial burden for our healthcare system.
Cytomedix, Inc. is an autologous regenerative therapies company commercializing innovative platelet technologies for wound care. The Company markets the AutoloGel™ System, a device for the production of autologous platelet rich plasma ("PRP") gel for use on a variety of exuding wounds.
