According to the results reported on ClinicalTrials.gov, this trial (NCT04604652) enrolled 24 adult participants, all of whom completed the study — none dropped out. All participants had a liver condition called primary biliary cholangitis (PBC) and had not responded well enough to their standard treatment. Every participant received the same investigational medicine, HTD1801, at a dose of 1,000 mg twice daily for 12 weeks. The trial was measuring changes in several blood markers — substances that doctors use to monitor liver and immune system activity — comparing levels at the start of the study to levels after 12 weeks. The reported data shows the following changes from the start of the study to week 12. The main thing being measured was a liver enzyme called alkaline phosphatase (ALP): the reported average change was a reduction of 7.7%. For the additional measures, total bilirubin (a substance that can build up when the liver is under stress) fell by an average of 0.10 mg/dL; a liver enzyme called GGT fell by an average of 34.1 U/L; total cholesterol fell by an average of 18.8 mg/dL; and an immune-system protein called IgM fell by an average of 36.8 mg/dL. Finally, something called the GLOBE score — a calculated risk tool used in PBC — fell by an average of 0.07 points. The reported data notes that reductions in these markers are generally considered to point in a favourable direction, but this trial alone does not establish what these changes mean for longer-term health outcomes. It is worth noting that this was a small, single-group study with no comparison group receiving a different or dummy treatment, which limits how the numbers can be interpreted.

Who might be able to join this trial:
- You have been diagnosed with a liver condition called Primary Biliary Cholangitis (PBC), confirmed by at least two of the following: abnormal liver enzyme levels in your blood, a positive blood test for a specific antibody (AMA), or a liver biopsy showing a particular pattern of damage
- You have been taking a medication called UDCA (ursodeoxycholic acid) at the right dose for at least 6 months, and your liver enzyme levels (ALP) are still higher than normal despite this treatment
- If you take a medication called cholestyramine (or similar) for itching, you have been on a stable, once-daily dose for at least 8 weeks, and you are willing to take it at least 2 hours before or after the study medication
- If you are a woman who could become pregnant, or a man, you agree to use at least two approved forms of barrier contraception, or to abstain from sex throughout the study and for three months after finishing the study drug (post-menopausal women must provide appropriate documentation)
- You are able to give your own informed consent to take part
Who may not be able to join:
- You have a related liver condition called autoimmune hepatitis (AIH) that is not well controlled, or you are taking high doses of steroids or azathioprine for it
- You have a history of alcohol or drug misuse
- You have previously had a liver transplant, or you are currently on a waiting list for one
- You have a history of chronic hepatitis B or hepatitis C infection
- Your blood test results show certain signs of advanced liver disease, such as low platelet count, low albumin, abnormal clotting, or you have a history of fluid build-up in the abdomen, confusion caused by liver disease, or bleeding from swollen veins in the food pipe
- Your bilirubin levels (a measure of liver function) are too high, unless this is caused by a harmless inherited condition called Gilbert's Syndrome (confirm with trial site)
- Your haemoglobin level (a measure of red blood cells) is below a certain level, indicating anaemia
- Your thyroid hormone levels are too high or too low (you may be able to re-apply once this is treated)
- Your kidneys are not working well enough (confirm with trial site)
- You have HIV-1 or HIV-2
- You have a condition called G6PD deficiency (a genetic enzyme disorder)
- You have had cancer in the past 2 years, or currently have cancer, with certain exceptions such as some types of skin cancer
- You have had a serious infection requiring strong antibiotic or antifungal treatment through a drip within the past 30 days
- You have had a major operation within the past 30 days, or have had a solid organ transplant at any point
- You are currently pregnant or breastfeeding
- You are currently receiving, or are expected to receive, radiation therapy, chemotherapy, or certain immune-modifying treatments
- You have another condition that causes raised ALP levels unrelated to your liver (e.g., a bone condition such as Paget's disease)
- You are allergic to the study drug or any of its ingredients
- You have taken part in another clinical trial or taken an experimental medication within the past 28 days
- You have taken certain cholesterol-lowering medications (bezafibrate or fenofibrate) within the past 28 days
- You have taken a medication called obeticholic acid (OCA) within the past 28 days
- You have any other condition or circumstance that the trial doctor believes would make it unsafe or unsuitable for you to participate
