Putting Research to the Test

In some people, the liver makes an abnormal version of the alpha-1 antitrypsin (AAT) protein, called Z-AAT. Making an abnormal version of the AAT protein can result in liver disease as Z-AAT builds up in liver cells, which leads to liver problems such as liver scarring (fibrosis), continuing liver damage (cirrhosis), and eventually endstage liver disease. Fazirsiran is a medicine that reduces the creation of the Z-AAT protein and thus the build-up of this abnormal protein in the liver. People with this type of liver disease who already have mild liver scarring will take part in the study. They will be treated with fazirsiran or a placebo for about 2 years. This study will check the long-term safety of fazirsiran and if participants tolerate the treatment. A liver biopsy, a way of collecting a small tissue sample from the liver, will be taken twice during the study.

Participants will be enrolled to receive multiple subcutaneous injections of fazirsiran (TAK-999, ARO-AAT). All eligible participants will require a pre-dose biopsy completed as part of the study within the screening window. All participants will undergo an End of Study (EOS) biopsy. Treated participants will be offered the opportunity to continue treatment in an open label extension during which they will undergo a final biopsy.

This is a Phase 1/2a double-blinded, placebo-controlled, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single and multiple ascending doses of ARO-DM1 compared to placebo in male and female subjects with Type 1 Myotonic Dystrophy (DM1). Participants who have provided written informed consent and met all protocol eligibility requirements will be randomized to receive single (Part 1) or multiple (Part 2) doses of ARO-DM1 or placebo.

The purpose of this study is to measure improvements in liver fibrosis and inflammation with GSK4532990 compared with placebo in participants with NASH and advanced (F3) fibrosis. The study duration will be up to 76 weeks including the screening period. The treatment duration will be up to 52 weeks.

The primary objective of this study is to compare the effect of treatment with olpasiran, to placebo, on the risk for coronary heart disease death (CHD death), myocardial infarction, or urgent coronary revascularization in participants with atherosclerotic cardiovascular disease (ASCVD) and elevated Lipoprotein(a).

Evaluate the effect of olpasiran administered subcutaneously (SC) compared with placebo, on percent change from baseline in lipoprotein(a) (Lp[a]).

The purpose of this study is to understand how the drug GSK4532990 is processed in the body (pharmacokinetics) and how it works in the liver (pharmacodynamics) as well as to ensure it is safe and well-tolerated. The total study duration for each participant will be approximately 24 weeks.

This study is an intervention specific appendix to the Hepatitis B wings platform trial (PLATFORMPAHPB2001). The study title reflects the original study design and JNJ-56136379 (JNJ-6379) was initially part of the study intervention but has been removed as part of amendment 3 of the study.

The purpose of this study is to evaluate the pharmacokinetics (PK) of a single subcutaneous (SC) dose of JNJ-73763989 in adult participants with renal impairment compared with healthy participants with normal renal function.

Hepatitis B virus (HBV) is a small deoxyribonucleic acid virus that specifically infects the human liver. The acute phase of infection is either followed by an immune controlled state or progresses to chronic hepatitis B. The worldwide estimated prevalence of chronic HBV infection is about 292 million people affected. Hepatitis B surface antigen (HBsAg) seroclearance is currently considered to be associated with the most thorough suppression of HBV replication (termed functional cure). With current available NA treatment strategies, rate of HBsAg seroclearance remains very low (around 3 percent [%]) even under long-term treatment. Also, with the persistently high global prevalence of HBV-associated mortality, there is a medical need for more effective finite treatment options that lead to sustained HBsAg seroclearance. JNJ-73763989 is a liver-targeted antiviral therapeutic for subcutaneous injection designed to treat chronic HBV infection via a ribonucleic acid interference (RNAi) mechanism. JNJ-56136379 is an orally administered capsid assembly modulator (CAM) that is being developed for the treatment of chronic HBV infection. The aim of the study is to evaluate the efficacy of a treatment regimen of JNJ-73763989 + PegIFN-alpha-2a + NA with or without JNJ-56136379 in participants with hepatitis B e antigen (HBeAg) positive chronic infection. The study will be conducted in 4 phases: a screening phase, an induction phase with flexible duration, a consolidation phase with or without PegIFN-α2a and a follow-up phase. Safety assessments will include Adverse Events (AEs), serious AEs of the study interventions, clinical laboratory tests, Electrocardiograms (ECGs), vital signs, and physical examinations. The study title reflects the original study design and JNJ-56136379 (JNJ-6379) was initially part of the study intervention but was discontinued as per amendment 6 of the study.
