Results show women undergoing reconstructive surgery following mastectomy who received AeroForm able to complete expansion and reconstruction faster than women who received traditional saline-based expanders

PALO ALTO, Calif., November 29, 2016: AirXpanders, Inc., (ASX: AXP) (AirXpanders or Company), a medical device company focused on the design, manufacture, sale and distribution of the AeroForm Tissue Expander System, announced that pivotal trial data from its XPAND study on AeroForm was published in the December issue of Plastic and Reconstructive Surgery, the official journal of the American Society of Plastic Surgeons.
AeroForm is currently available in Australia and under review with the U.S. Food and Drug Administration.

AeroForm is designed to offer women who choose reconstructive surgery following a mastectomy a needle-free alternative for tissue expansion. AeroForm is activated by a handheld wireless controller that administers small amounts of carbon dioxide (CO2) up to three times a day, to gradually stretch the tissue to prepare for reconstruction. With the push of a button from a remote controller, the programmed amount of CO2 is delivered in seconds, allowing the patient to continue with her daily activities while preparing for reconstruction.

The XPAND study evaluated AirXpanders' AeroForm Tissue Expander System compared to traditional saline expanders in a randomized, controlled trial that included 150 patients across 17 sites in the U.S. Study data demonstrated that with AeroForm, patients were able to complete tissue expansion in an average of 21 days, compared to an average of 46 days for the saline group. The study also demonstrated that both study groups achieved successful exchange to an implant with similar safety profiles. AirXpanders submitted the results of the XPAND study to the U.S. Food and Drug Administration (FDA) as part of the Company's de novo dossier, submitted late last year.

"Fear of a time-consuming and potentially uncomfortable medical process can deter women who have undergone mastectomy from having reconstruction," said Jeffrey Ascherman, M.D., site chief of the Division of Plastic Surgery NewYork-Presbyterian/Columbia University Medical Center and principal investigator for AirXpanders' U.S. XPAND study. "This study is further evidence that AeroForm could improve the standard of care for reconstruction, enabling women to complete reconstruction faster and with greater control over the process."

"Publication of the XPAND data validates AeroForm and its potential to provide plastic surgeons and patients with what we believe is one of the first major advancements in two- stage breast reconstruction in more than 40 years," said Scott Dodson, president and CEO, AirXpanders. "We look forward to working with FDA to bring this revolutionary technology
to surgeons and women in the U.S. and continuing our efforts to expand access to AeroForm globally."
