Adipose-Derived Stem Cells Show Promise in Breast ReconstructionResults Reported at the 30th San Antonio Breast Cancer Symposium
SAN DIEGO--(HSMN NewsFeed)--Cytori Therapeutics (NASDAQ:CYTX ) received results from an independent, investigator-sponsored study in Japan in which adipose tissue-derived stem and regenerative cells were used for breast reconstruction following partial mastectomy. The study data were presented today at the 30th San Antonio Breast Cancer Symposium (Poster #4071).
The novel procedure evaluated 21 women with no metastases or recurrence at least one year after partial mastectomy. Among key findings:
- The procedure was reported safe and well tolerated in all women
- No rejection or immune response was observed
- Patient satisfaction of the outcome was 79 percent, with a mean follow up period of 7.7 months
- There was a statistically significant improvement in average breast tissue thickness at one month following treatment and at final assessment compared to baseline
- There was no significant loss of tissue thickness between one month and the final assessment
“This clinical series is an exciting, early development for women with breast cancer who undergo partial mastectomy,” said Marc H. Hedrick, M.D., president for Cytori Therapeutics. “The reported data suggest this novel procedure can be safely performed, is clinically practical for surgeons to implement, and confirms Cytori’s decision to initiate clinical trials intended to establish efficacy, ascertain volume retention, and measure the magnitude of aesthetic and functional improvement.
“Reconstructive options have not kept pace with the development of new cancer therapies and existing reconstructive options for women are either ineffective, impractical or both. Until now, partial mastectomy patients have had little hope other than to live with tissue loss. This procedure holds the potential to offer women the opportunity to restore the contour, volume and function lost during cancer treatment.”
Two clinical studies will be initiated next year in Europe by Cytori to further evaluate adipose-derived stem and regenerative cells, processed with the Celution™ System, in breast reconstruction following partial mastectomy. One study, RESTORE II, will evaluate up to 70 patients at multiple trial sites. A second study, VENUS, will be a 20-patient single center study in patients with more severe radiation damage and contour defects.
Fat, known medically as adipose tissue, is one of the body’s richest and most accessible sources of regenerative cells. Adipose-derived regenerative cells include adult stem cells in addition to other important cell types that have been shown pre-clinically to improve volume retention and graft persistence. For this reason, these cells potentially may improve and simplify traditionally complex fat transfer procedures as well as enable more predictable outcomes when applied to cosmetic and reconstructive surgery.
More than one million women worldwide are diagnosed with breast cancer annually, including more than 370,000 women in Europe and more than 240,000 in the United States. Due to continual advancements in cancer detection, a growing percentage of women are eligible for partial versus full mastectomies. Unfortunately, partial mastectomy often results in significant skin damage, tissue loss, pain, and reduction or loss of motion. Women who undergo such procedures have limited reconstructive options to potentially reduce associated pain, reverse loss of motion, and restore breast volume and contour.
Cytori Therapeutics’ (NASDAQ:CYTX ) goal is to be the global leader in regenerative medicine. The company is dedicated to providing patients with new options for reconstructive surgery, developing treatments for cardiovascular disease, and banking patients’ adult stem and regenerative cells. To reach its goal, Cytori is developing its innovative Celution™ System to separate and concentrate a patient’s own adult stem and regenerative cells from adipose (fat) tissue for these cells to be delivered back to the patient during the same surgical procedure. The Celution™ System will be introduced in 2008 in Europe for reconstructive surgery and launched in Japan for cryopreserving a patient’s own stem and regenerative cells. Clinical trials are ongoing or planned in cardiovascular disease, spinal disc degeneration, gastrointestinal disorders, and other unmet medical needs. www.cytoritx.com
