AirXpanders and Radformation Announce Co-Marketing Agreement

— Partnership Designed to Bring Improved Workflow to Radiation Oncology Departments

AirXpanders, Inc. (ASX: AXP), a medical device company focused on the design, manufacture, sale and distribution of the AeroForm(R) Tissue Expander System, and Radformation, Inc., a software company co-founded by medical physicists dedicated to bringing intelligent automation software in cancer care, including breast and breast reconstruction radiation therapy treatment planning, announced today that they have entered into a co-marketing agreement to introduce Radformation’s EZFluence software to Radiation Oncology departments that are treating AeroForm patients in the US.

The co-marketing agreement enables AirXpanders sales personnel to introduce the EZFluence software to radiation oncology departments who are treating a growing number of patients with the AeroForm Tissue Expander System. This collaboration is expected to improve acceptance of the AeroForm Expander by significantly improving the workflow required to develop radiation treatment plans. By collaborating on the introduction of the EZFluence software, both organizations expect Radiation Oncology departments to benefit from the intelligent automation of radiation therapy treatment planning for breast reconstruction patients.

“We have been very impressed with the EZfluence software,” said Mark Payne, VP, Research and Development of AirXpanders. “The intelligent automation this software provides for opposed tangent fields, using both field-in-field and E-comp techniques, is impressive in its thoroughness and ability to effectively develop a radiation treatment plan in minutes from a patient CT scan. The plans developed by this software exhibit significantly improved homogeneity compared to conventionally-determined iterative plans. We expect radiation oncology departments will appreciate the dramatic reduction in the time needed to develop a treatment plan for patients with an AeroForm, and an overall increase in their productivity for all their breast radiation treatment plans. We are excited to train up our team, and introduce our customer base to this advancement in radiation treatment planning automation.”

“Radformation is excited to work with a company that empowers patients and values their interests,” said Elisabeth van Wie, Medical Physicist and Chief Business Officer of Radformation.

“AirXpanders’ goal is to make the patient more comfortable during a difficult time in their lives while maintaining quality treatment. We support this goal and look forward to working with clinics on generating optimal radiation treatment plans for patients.”

Radformation’s EZFluence is FDA cleared and available in the US since 2017. With a rapidly growing installed base, a growing number of Radiation Oncologists and Medical Physicists are utilizing the system, and experiencing the productivity improvements it provides. As a plug-in script for Varian’s Eclipse system, EZFluence is straightforward to use and easy to adopt.

“EZFluence is a treatment planner’s best friend for any plan which uses opposed beams. The AeroForm Tissue expander poses some unique challenges but with EZFluence we were able to get an optimal plan in a short amount of time,” said Scott Dube, Medical Physicist at Morton Plant Hospital, Clearwater, FL.

As part of the agreement, the companies are developing plans to collaborate and educate at key Radiation Oncology and Medical Physics society meetings throughout 2019.
