Trial Outcomes & Findings for MEDTRUM A7+ TouchCare Insulin Patch Pump (MedInPS) (NCT NCT04223973)

NCT ID: NCT04223973

Last Updated: 2024-08-16

Results Overview

A1C will be estimated by a Continuous Glucose Measurement (FreeStyle Libre®) for all patients, at baseline and end of the study (12 weeks). The main objective is to demonstrate Non-inferiority efficacy (PP then ITT) of Medtrum A7+ insulin patch pump vs Insulet Omnipod® insulin patch pump (2 randomized groups). For the primary outcome, A1C will be estimated and appear in percentage based on assessment done by a Continuous Glucose Monitoring system. The A1C obtained in real life for the group using the comparator pump (Omnipod®) is estimated at 7.8%. Assuming that blood glucose level will be the same with Medtrum pump and based on a defined non-inferiority margin ∆ = + 0.4 (following FDA Guidance for Industry Diabetes Mellitus: Developing Drugs and Therapeutic Biologics for Treatment and Prevention).

Participant Flow

Date of recruitment: January 2020 to February 2021 \> total duration 13 months 8 investigational centres mainly hospitals (General and University Hospitals)

Due to Covid 19 pandemia some clinical sites Research Department decided to stop recruitment or put interventional arm of the protocol of test on hold. As consequence of this, some participants where withdrawn. Mainly in Active group as in the control group patients were using their usual devices and treatment and they resumes follow up visits as usual.
