Putting Research to the Test

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.

The purpose of the study is to evaluate the single-dose pharmacokinetic (PK) of JNJ-73763976 and JNJ-73763924 following a subcutaneous (SC) injection of JNJ-73763989 (JNJ-3989) in participants with liver cirrhosis and various degrees of impaired hepatic function when compared with healthy participants with normal hepatic function and no liver cirrhosis.

Hepatitis B virus (HBV) is a small deoxyribonucleic acid (DNA) virus that infects the liver and can cause either acute or chronic infection. It consists of a so-called nucleocapsid in which viral DNA is packed with hepatitis B core protein (HBc) and membranous envelope containing hepatitis B surface antigen (HBsAg). Chronic HBV infection may lead to serious illnesses like cirrhosis and hepatocellular carcinoma (HCC). Oral treatment with NAs is effective at suppressing viral DNA formation and lowering virus concentration in blood to levels below lower limit of quantification (LLOQ). JNJ-73763989 is a liver-targeted antiviral therapeutic for subcutaneous injection designed to treat chronic HBV infection via ribonucleic acid interference mechanism but rarely lead to functional cure defined as sustained loss of HBs Ag and HBV DNA in serum. JNJ-56136379 is an orally administered capsid assembly modulator that is being developed for treatment of chronic HBV infection. The aim of study is to evaluate efficacy of 48-week study intervention with JNJ-3989+JNJ-6379+NA regimen compared to NA alone, assessed by HBsAg seroclearance at Week 72 (i.e., 24 weeks after completion of all study interventions at Week 48) without restarting NA treatment in HBeAg negative virologically suppressed chronic hepatitis B (CHB) infected participants who received NA treatment for at least 2 years prior to screening. The study will be 2.3 years and will be conducted in 3 phases: a screening phase (4 weeks), a study intervention phase (48 weeks), and a follow-up phase (48 weeks). Safety will be evaluated by AEs including AEs of special interest to any of the study interventions, clinical laboratory tests, ECGs, vital signs, and physical examinations.

The purpose of this study is to investigate the pharmacokinetics, safety, and tolerability of JNJ-73763989 in healthy Japanese adult participants following single-dose subcutaneous administration of 3 different doses of JNJ-73763989, Dose Level 1 (Panel A), Dose Level 2 (Panel B) or Dose Level 3 (Panel C).

The title of protocol reflects the original study design. The study design section is reflecting that the design as of protocol amendment 5 is non-randomized.
