According to the results reported on ClinicalTrials.gov, this trial looked at a treatment called All-trans Retinoic Acid (ATRA) in people with a liver condition. The trial set out to measure changes in certain blood markers — including a liver enzyme called alkaline phosphatase (ALP), bile acids, and other indicators of liver health — by comparing blood test results before and after treatment. Only 2 people enrolled in the trial, 1 of whom completed it and 1 of whom did not finish. The reported data shows that no numerical results were submitted to ClinicalTrials.gov for any of the outcome measures — neither the primary measure (change in ALP levels) nor any of the six secondary measures (such as changes in bile acids, liver enzymes, or a liver scarring score). Because no measurement data was reported, it is not possible to describe what the blood tests showed for either participant. Given the very small number of participants and the absence of any reported numerical results, the data as submitted does not allow any conclusions to be drawn about the outcomes being studied. These are the results as reported to ClinicalTrials.gov. They are not medical advice — always discuss what they mean for you with your doctor.
