Clinical Trial Summary

This will be a single center, methodological study in healthy male subjects to evaluate the intra-period, inter-period and inter-observer reproducibility of flow measurements in the superior mesenteric artery, using Doppler Ultrasound.

Description:

This will be a single center, methodological study in healthy male subjects, aged 18-50, to evaluate the intra-period, inter-period and inter-observer reproducibility of flow measurements in the superior mesenteric artery, using Doppler Ultrasound.

Eligibility

Inclusion Criteria:

• Subject is a male =18 and = 50 years of age.

• Subject is a non-smoker for at least 6 months prior to study start.

• Subject has a body mass index between 18-28 kg/m2.

• Subject is judged to be in good health on the basis of medical history and vital signs.

• Subject understands the procedures and agrees to participate in the study by giving written informed consent.

Exclusion Criteria:

• Subject has a history of any illness which, in the investigator's opinion, might confound the results of the study.

• Subject has burns, scars, flaps or grafts on the abdomen which, in the investigator's opinion, may interfere with the study assessments.

• Subject has an anatomical anomaly of the SMA as evaluated with DUS during screening which, in the investigator's opinion, may interfere with the study assessments.

• Subject currently uses any prescription or non-prescription drugs on a regular basis which, in the investigator's opinion, might confound the results of the study. Subject has taken 7 days prior to the start of the study any prescription or non-prescription drugs which, in the investigator's opinion, might confound the results of the study.

• Subject is unable to refrain from drinking alcohol 24 hours prior to each study visit or has a history of drug (including alcohol) abuse.

• Subject has any of the following vital sign measurements at screening: Heart Rate <40 or >100 beats/min, Diastolic Blood Pressure <50 or >90 mmHg, Systolic Blood Pressure <90 or >140 mmHg.

• Subject has been involved in testing an investigational drug in another clinical study within the last 4 weeks.

• Subject is in a situation or has a condition which, in the opinion of the investigator, may interfere with optimal participation in the study.
