First-in-Human Abdominal Aortic Aneurysms trial with Tricaprin (F-HAAAT)

Basic Information

Recruitment status Recruiting
Health condition(s) or Problem(s) studiedAbdominal Aortic Aneurysm
Date of first enrollment21/06/2024
Target sample size10
Countries of recruitment
Study typeInterventional
Intervention(s)Administer Caprin HI 800 mg (2 tablets), containing 500 mg of tricaprin, three times a day after each meal (total 6 tablets/day) for two weeks. After confirming that no unpredictable intolerance symptoms have occurred by a medical examination, the dosage will be increased to Caprin HI 1600 mg (4 tablets), containing 1000 mg of tricaprin, three times a day after each meal (total 12 tablets/day) for 50 weeks (a total of 52 weeks on oral administration of Caprin HI). If a dose is missed, take two doses at the next scheduled administration time. If all doses (morning, noon, and evening) are missed, take two doses before bedtime.

Outcome(s)

Primary OutcomeFrequency of adverse events Also, the additional analysis for (1) - (3) below will be performed. (1) Major adverse cardiovascular events (cardiovascular deaths, non-fatal myocardial infarction, non-fatal cerebrovascular stroke) (2) Serious abdominal aortic aneurysm-related events (persistent non-fatal acute abdominal or back pain with proven rupture, persistent non-fatal acute abdominal or back pain with unproven rupture, sudden color change in extremities with severe pain or lower extremity edema, abrupt demand for the surgical treatment, etc.) (3) Other (investigational treatment-related adverse events that cannot be classified into (1) to (2))
Secondary OutcomeThe following items related to efficacy indicators will be explored: (1) Changes in maximum minor short-axis diameter and aneurysm volume of abdominal aortic aneurysm (2) Analysis of the intra-aneurysmal aortic wall CT values (3) Agatston score of abdominal aortic aneurysm (measured within the same range of the aneurysm volume measurement)
