PERFORMANCE STUDY OF THE AL-SENSE

• Status: Completed
• Phase: Phase 3
• Study type: Interventional
• Enrollment: 352 (actual)
• Sponsor: Common Sense · Academic / Other
• Sex: Female
• Age: 18 Years – 55 Years
• Healthy volunteers: Accepted

Summary

This is an open-label, comparative, and prospective pivotal study to demonstrate that AL-SENSE can indicate whether wetness sensed by pregnant women may be caused by amniotic fluid leakage rather than by urinary incontinence. Subjects arriving at the hospital will receive a single AL-SENSE to use until they notice any wetness. The blinded physician will perform a diagnosis according to the standard diagnostic methods (clinical assessment). The standard diagnostic methods will include the following tests: (1) Pooling test, (2) Ferning test, (3) pH test by pH paper. A positive Pooling test or positive result in both the pH test and the Ferning test is defined as a positive clinical assessment.

Detailed description

This is an open-label, comparative, and prospective pivotal study to demonstrate that AL-SENSE can indicate whether wetness sensed by pregnant women may be caused by amniotic fluid leakage rather than by urinary incontinence. Subjects arriving at the hospital and reporting unidentified wetness (undetermined whether this is amniotic fluid leakage or urinary incontinence) will receive a single AL-SENSE to use up to 12 hours or until they notice any wetness. The clinician will explain the proper use and handling of the AL-SENSE. In each case, the blinded clinician will be required to read and record any occurrence of color change of the AL-SENSE 10 minutes after the AL-SENSE removal and to mark if it changes color to blue or to green on the designated form. The blinded physician (other than the clinician who records the AL-SENSE results) will perform a diagnosis according to the standard diagnostic methods (clinical assessment). The standard diagnostic methods will include the following tests: (1) Pooling test, (2) Ferning test, (3) pH test by pH paper. A positive Pooling test or positive result in both the pH test and the Ferning test is defined as a positive clinical assessment. In cases where the AL-SENSE shows positive results but the clinical assessment results are negative, reference laboratories, or any other standard procedure will check for the possibility of BV or Trichomonas in addition to the tests noted above.
