Item 8.01. Other Events.

On July 24, 2017, Cytori Therapeutics, Inc. (the “Company” or “Cytori”) announced top-line, preliminary data from its Phase III pivotal STAR trial of  Habeo™ Cell Therapy™ in patients with scleroderma.  The U.S. multi-center STAR trial enrolled and evaluated 88 patients with scleroderma, including 51 patients within the diffuse cutaneous subset and 37 with limited cutaneous scleroderma.  While the primary endpoint did not reach statistical significance at 24 or 48 weeks, the trial data reported clinically meaningful improvement in the primary and secondary endpoints of both hand function and scleroderma-associated functional disability, for Habeo treated patients compared to placebo, in a subgroup of patients with diffuse cutaneous  scleroderma.

In the combined study population, the primary endpoint, specifically mean improvement in the Cochin Hand Function Score, did not show statistical difference between treated patients and those receiving placebo at 24 weeks and 48 weeks as determined by both analysis of covariance and mixed model repeated measure analysis.  The Raynaud’s Condition Score, a secondary endpoint, improved in both the treatment and placebo group but was not statistically different between the Habeo-treated and placebo groups.

However, in the pre-specified subgroup analysis of patients with diffuse cutaneous scleroderma, a more severe form of the disease, improvements in the Cochin Hand Function Score and the Health Assessment Questionnaire-Disability Index (HAQ-DI), a measure of functional disability and an important secondary endpoint, met or exceeded the published criteria for minimally important clinical differences in these measures (6.5 points for Cochin¹, 0.22 points for HAQ-DI²).

In general, the adverse events were rated as mild to moderate in the majority of cases and there were no significant safety issues identified for Habeo or the procedure itself (including liposuction and finger injection in the placebo group) during the trial.

After Cytori reviews the complete data set from the STAR trial, Cytori plans to work collaboratively with trial investigators, patient advocates and the regulatory bodies in Cytori’s key markets, to evaluate the next steps for Habeo Cell Therapy.  

The STAR trial was a prospective, double-blind, randomized, multicenter, parallel-group Phase III pivotal study assessing the safety and efficacy of a single, subcutaneous administration of Habeo Cell Therapy (40 million cells per subject) into the fingers of patients with hand dysfunction due to scleroderma. The subjects were randomized 1:1 to receive either Habeo Cell Therapy or placebo. Investigators conducted final assessments at 48 weeks.  The primary study endpoint was improvement in the Cochin Hand Function Score, a self-reported measure of hand function, which was assessed at 24 and 48 weeks. The Cochin score is based on 18 questions relating to hand function; each question is graded on a 0–5 scale, with a total score of 90 points reflecting maximal disability.  The Health Assessment Questionnaire-Disability Index (HAQ-DI), a measure of functional disability and a secondary

endpoint in the STAR trial, consists of questions pertaining to activities of daily living graded on a 0–3 scale (with 3 representing “unable to perform”); the HAQ-DI also includes several visual analog scales (VAS) for different body systems.   The Raynaud’s Phenomenon condition score, a secondary endpoint in the STAR trial, is a patient reported outcome measure asking the patients how much difficulty they had with their Raynaud’s symptoms over the past 24 hours graded on a scale of 0 – 10 with 0 being no difficulty and 10 being extreme difficulty.

Such statements, include, but are not limited to, statements regarding Cytori’s plans to evaluate the STAR data in consultation with various internal and external resources, experts and the FDA; Cytori’s conduct of its STAR trial, and possible future clinical trials of Habeo Cell Therapy; the ability to fully characterize the efficacy and safety profile of Habeo Cell Therapy through further study and the potential to yield additional insights into its clinical utility; and the ability of Cytori Cell Therapy™ to provide benefits across multiple disease states and be made available to the physician and patient at the point-of-care through Cytori’s proprietary technologies and products.  These statements are subject to risks and uncertainties that could cause Cytori’s actual results and financial position to differ materially. Some of these risks and uncertainties include: risks in the conduct of Cytori’s STAR trial and future clinical trials (including risks in the collection and results of clinical data); risks associated with the conduct of investigator-initiated trials using our cellular therapeutics; risks associated with potential benefits of Cytori’s products (including any potential benefits of Habeo Cell Therapy identified in the STAR trial); risks associated with development of Cytori’s clinical pipeline, including the possibility that Cytori may determine that there may not be a viable continued development path for Habeo Cell Therapy; final clinical outcomes (including the risk that top-line data may not accurately reflect the complete results of a particular study or trial); regulatory risks and uncertainties, including the risk that FDA and other regulatory authorities may not approve Habeo Cell Therapy, or that any marketing approvals, if granted, may have significant limitations on their use; risks related to reimbursement (including failure to achieve desired pricing for Habeo Cell Therapy); risks related to dependence on third party performance; the risk that Habeo Cell Therapy may never be successfully commercialized, or receive anticipated levels of commercial acceptance; Cytori’s ability to raise additional funding that it may need to continue to pursue its commercial and business development plans; and other risks and uncertainties described under the "Risk Factors" section in Cytori's Securities and Exchange Commission filings on Form 10-K and Form 10-Q.
