Interventions

DEVICECT-155 smartphone app

The CT-155 study app is designed to provide treatment monitoring and educational components of a full treatment cycle with CT-155. This design allows inferences to be made about the usability and acceptability of CT-155. Eligible participants will be enrolled during an in-person clinic visit on Day 1. Participants will then be directed to access the study app and perform tasks each day for the 49-day engagement period.
