Trial Outcomes & Findings for Evaluation of an Karajishi TS Investigational Blood Glucose Monitoring System (NCT NCT02041377)

NCT ID: NCT02041377

Last Updated: 2016-02-29

Results Overview

Subjects with diabetes self-tested fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS) with no training. BGMS results were compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer BG results were used to calculate the number of BGMS results within +/-15 mg/dL (\<100 mg/dL YSI capillary plasma) and +/-15% (\>=100 mg/dL YSI capillary plasma).

Intended Users of the Monitoring System
Subjects with diabetes used the Karajishi TS Investigational Blood Glucose Monitoring System with no training. The criteria for the intended use population: 1. At least 60% of subjects will be younger than age 65 2. At least 10% of subjects will have type 1 diabetes Karajishi TS Investigational Blood Glucose Monitoring System: Subjects with diabetes performed self Blood Glucose (BG) tests with capillary fingerstick and palm blood using the Karajishi TS Investigational Blood Glucose Monitoring System with no training. All BG results were compared to reference method results obtained from subject capillary plasma. Also, study staff tested subject venous blood and BG results were compared to reference method results obtained from subject venous plasma.

PRIMARY outcome

Timeframe: 1 hour

Population: 132 (134-2)Blood glucose results were analyzed. Lab reference replicates for one subject were discrepant and not evaluable per protocol. One subject had no fingerstick result.

Subjects with diabetes self-tested fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS) with no training. BGMS results were compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer BG results were used to calculate the number of BGMS results within +/-15 mg/dL (\<100 mg/dL YSI capillary plasma) and +/-15% (\>=100 mg/dL YSI capillary plasma).

SECONDARY outcome

Timeframe: 1 hour

Population: 131 (134-3) Blood glucose results were analyzed. Lab reference replicates for one subject were discrepant and not evaluable per protocol. Venipuncture was not successful for 2 subjects.

Study staff tested subject venous blood using an investigational Blood Glucose Monitoring System (BGMS). Venous BGMS results were compared with subject venous plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer venous plasma BG results were used to calculate the number of BGMS results within +/-15 mg/dL (\<100 mg/dL YSI venous plasma) and +/-15% (\>=100 mg/dL YSI venous plasma).

SECONDARY outcome

Timeframe: 1 hour

Population: 129 (134-5) Blood glucose results were analyzed. Lab reference replicates for one subject were discrepant and not evaluable per protocol. One subject had low blood sugar and AST result was not evaluable per protocol. One subject with low blood sugar did not attempt AST testing per protocol. No AST palm results were obtained for 2 subjects.

Subjects with diabetes self-tested Alternative Site (AST) palm blood using an investigational Blood Glucose Monitoring System (BGMS) with no training. BGMS AST palm results were compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer. YSI Analyzer BG results were used to calculate the number of BGMS results within +/-15 mg/dL (\<100 mg/dL YSI capillary plasma) and +/-15% (\>=100 mg/dL YSI capillary plasma).

Population: 133 (134-1) Blood glucose results were analyzed. Lab reference replicates for one subject were discrepant and not evaluable per protocol.

Study staff obtained and tested subject fingerstick blood using an investigational Blood Glucose Monitoring System (BGMS). BGMS results were compared with subject capillary plasma BG results obtained with a Yellow Springs Instrument (YSI) Analyzer.
