Human Factors Research Presented at DTM 2017 Demonstrates Ease of Use and Effectiveness of Computer-Based Training for Touchscreen Insulin Pump with Automated Insulin Delivery Feature

SAN DIEGO--()--Tandem Diabetes Care®, Inc. (NASDAQ: TNDM), a medical device company and manufacturer of the only touchscreen insulin pumps available in the United States, today presented results from a Human Factors study conducted to validate the safety of the user interface of a predictive low glucose suspend (PLGS) feature as part of the t:slim X2™ Insulin Pump. The study included users ages 6 and up (N=53), with and without experience using an insulin pump or continuous glucose monitoring (CGM). The study demonstrated a 99 percent success rate among study participants who performed a series of critical tasks using the PLGS system after initial training. Out of 530 tasks performed, only seven task failures were observed, none of which were related to safety. These data were presented today during a poster session at the 2017 Diabetes Technology Meeting (DTM) in Bethesda, Maryland.

“This study demonstrates that the t:slim X2 System with PLGS requires minimal training and is easy to use, even for people without pump or CGM experience,” said Betsy Dokken, PhD, Director of Clinical Affairs at Tandem Diabetes Care. “We believe that the high success rate and minimal errors observed in this study highlight the importance of human factors research in insulin pump development, particularly with the introduction of automated insulin delivery algorithms.”

The study was conducted at four independent research centers in the United States. Training consisted of live one-hour sessions on the t:slim X2 Pump and the Dexcom G5 Mobile CGM System with a break in between. These were waived for current Tandem and Dexcom users, or were shortened for those with previous pump and/or CGM experience. Participants then took a 45-minute computer-based training module on the PLGS feature. Following a one-hour break, they were asked to complete 10 critical tasks on the device in a simulated environment in order to uncover and identify errors and difficulties. Parents were permitted to help children. Interactions were observed and scored by a researcher seated in a separate observation room. Successful performance required completion of the task without any observed errors or assistance from the study moderator. Pass/fail scoring was completed according to pre-set criteria.

Data from a feasibility study on Tandem’s PLGS system was presented this summer at the 77th Scientific Sessions of the American Diabetes Association. A pivotal trial is currently underway and anticipated to be complete by the end of 2017. The Company is preparing to launch its t:slim X2 Pump with PLGS in the summer of 2018, subject to future U.S. Food and Drug Administration review and approval.
