Tandem announced it received FDA clearance for Control IQ as the first “interoperable automated glycemic controller device” (denoted as iAGC below and previously described as “iAlgorithm” by FENIX). Notably, FDA also issued a press release regarding the approval. With Control IQ’s approval, FDA has established new special controls for the final component of interoperable systems. Dexcom’s G6 CGM was the first interoperable CGM (iCGM), and Tandem’s t:slim X2 was the first alternate controller enabled pump (ACE pump). Below, FENIX provides insights on the Control IQ approval in the context of future interoperable systems in development as well as thoughts on how JDRF’s new plea to UHC could help Tandem expand access.
