Ab-729

Clinical trials are investigating Ab-729 in people with chronic HBV infection. The study data focus on safety, tolerability, and treatment-related reactions in NA-suppressed subjects. These trials help show how Ab-729 is being tested in a Phase 2 setting.

Clinical trials overview

The available trial data show one interventional study of Ab-729 in people with chronic HBV infection.[1] The study was titled an open-label study of imdusiran (AB-729) with intermittent dosing of durvalumab in subjects with chronic HBV infection.[1]

Ab-729 is described in the trial record as imdusiran (AB-729), and the study also used durvalumab, listed as IMFINZI, as part of the treatment plan.[1] The brief summary says the trial aimed to evaluate the safety and tolerability of imdusiran and durvalumab in NA-suppressed chronic HBV subjects.[1]

Who was studied

The target population was people with chronic HBV infection, meaning long-lasting hepatitis B infection.[1] The study specifically included NA-suppressed subjects, which means their hepatitis B virus was already being controlled with nucleic acid analog treatment.[1]

This focus matters because the trial was not designed for all people with hepatitis B, but for a more specific group whose virus was already suppressed.[1]

What the study tested

The trial tested Ab-729 together with intermittent dosing of durvalumab.[1] Intermittent dosing means the medicine is given at set times rather than continuously.[1]

The study used an open-label design, which means both the researchers and the participants knew what treatment was being given.[1] This type of design is often used when the main goal is to watch safety and tolerability closely.[1]

Study endpoints and safety checks

The primary outcome measures focused on safety.[1] These included the frequency and severity of treatment-emergent adverse events (TEAEs), immune-related adverse events (irAEs), and treatment stops because of these events.[1]

The study also measured laboratory abnormalities by cohort, which means researchers checked whether blood or other lab tests moved outside the normal range in each study group.[1] In addition, the trial tracked vital signs, physical exam findings, and electrocardiogram (ECG) abnormalities to watch for possible safety concerns.[1]

Trial status and size

The study was a Phase 2 trial, which is a mid-stage study that usually looks more closely at safety and early treatment effects.[1] The trial status was completed, and the enrollment was 30 participants.[1]

Because only one trial is listed in the source data, the current clinical picture for Ab-729 here is limited to this completed Phase 2 study in chronic HBV infection.[1]

Glossary

  • Chronic HBV infection: A long-term hepatitis B infection. It can stay in the body for many years and may need ongoing treatment and monitoring.
  • HBV: Short for hepatitis B virus, the virus that causes hepatitis B infection.
  • NA-suppressed: This means the hepatitis B virus is being controlled by nucleic acid analog treatment, so the virus level is kept low.
  • Nucleic acid analog (NA): A type of hepatitis B treatment used to lower the amount of virus in the body.
  • Interventional study: A clinical trial where researchers give a treatment and then watch what happens.
  • Phase 2: A mid-stage clinical trial that looks closely at safety and early signs of benefit.
  • Treatment-emergent adverse events (TEAEs): Health problems that start or get worse after treatment begins.
  • Immune-related adverse events (irAEs): Side effects linked to the immune system reacting in a harmful way during treatment.
  • Laboratory abnormalities: Test results that are outside the normal range, such as blood test changes.
  • Electrocardiogram (ECG): A test that records the heart’s electrical activity.
