Performance Study of the SOLO 2.0 Insulin Pump
Recruitment status was Recruiting
The Purpose of the study is to to evaluate the performance of the SOLO (version 2.0) micropump insulin delivery system, in Type 1 diabetic patients who use insulin pumps for their treatment.
|Study Design:||Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
- Device related safety issues [ Time Frame: with in the first month of use ] [ Designated as safety issue: Yes ]Subject complaints documented in the R&D questionnaire and Complaint Report Forms which were assessed and found to be device related safety issues.
- SOLO use errors [ Time Frame: within the first month of use ] [ Designated as safety issue: Yes ]Use errors or potential use errors reported in Subject Diary which may be related to SOLO safety.
- Device-related adverse outcome [ Time Frame: within the first month of use ] [ Designated as safety issue: Yes ]Device-related adverse outcome, such as significant skin irritation or infection at the attachment site
- Diabetes-related adverse outcome [ Time Frame: with in first month of use ] [ Designated as safety issue: Yes ]Diabetes-related adverse outcome. i.e. hypoglycemia, hyperglycemia and diabetic ketoacidosis (DKA) events.
- Satisfaction iwth SOLO [ Time Frame: within the first month of use ] [ Designated as safety issue: No ]
Subject satisfaction with SOLO as reported in:
- SOLO performance questionnaire
- DTSQ analysis
- Product quality (MTBF) [ Time Frame: within the first month of use ] [ Designated as safety issue: No ]
Product quality will be assessed by Mean Time Between Failures (MTBF) calculation that include three types of failure modes:
Type 1: Non-functional device Type 2: Dysfunction that can be recovered by the subject Type 3: Minor issues reported by the user
|Study Start Date:||July 2011|
|Estimated Primary Completion Date:||July 2012 (Final data collection date for primary outcome measure)|
Device: SOLO insulin pump
This is a multi center, one arm, open label and prospective study to assess the safety and quality of the SOLO 2.0 MicroPump Insulin Delivery System, following changes that were done to the SOLO previous version which was validated in 54 subjects.
SOLO 2.0 has the same intended use and core technology as previous SOLO with addition of safety measures, GUI changes and design changes for manufacturability.
The study will include a 30 days treatment period with the Solo MicroPump with no special care required for maintaining glycemic control and with an optional extension period of up to three month in Israel and up to six month in Austria.
The study includes 3 scheduled treatment and one follow up phone call one week after termination of the study. In case of participating the extension period, additional visits will consist once a month.
The study includes 3 scheduled treatment visits and one scheduled telephone call
Visit 1 includes eligibility, baseline evaluation and training in handling of the SOLO System. If no additional practice is required patients will be enrolled. Visit 2 will commence and Solo pump will be filled with insulin. If additional practice is required subject will be sent home for an additional training period of a few days practice using saline and then return for visit 2.
Treatment visits will take place at 3, 10 and 30 days after the enrolment. Additional visits will take place at 60, 90, 120 and 150 days depending on the extension period.
Medical assessment includes DTSQ information, Subject Diary, urine & blood sampling, physical examination, the SOLO Performance Questionnaire, R&D Questionnaire and Complaint Report Forms.Subjects will be asked to record blood glucose measurements, daily activities and carbohydrate consumptions between visits.
Seven days after termination of study treatment a telephone contact with the study subject will take place for the purpose of adverse event reporting and the completion of DTSQ questionnaire.
