Non-human primates (NHPs) share a wide range of genetic and physiological features in common with humans. Yet, despite their widespread use in preclinical research, NHP models suffer from several limitations that can lead to a lack of translatability in clinical trials.

It is estimated that 40% of drug candidates have failed to make it to market because of toxicity.¹ One of the most common adverse drug reactions is drug-induced liver injury (DILI), whereby patients experience acute illness, often with symptoms similar to hepatitis and cholestasis. Today, DILI is the leading cause of drug candidate failure and post-market withdrawals.² The high incidence of DILI in clinical trials, and even post-market events, is partly due to the use of conventional animal models at preclinical stages. Conventional models are notoriously poor predictors of efficacy and toxicity in the liver, due to species-to-species variation. In contrast, the PXB-mouse® model, with its humanized liver, provides a highly predictive model of human physiology and human-specific hepatotoxicity, allowing for more accurate prediction of human outcomes, and, therefore, aiding the smooth progression of new therapeutics into the clinic.

Hepatitis B is a serious and globally prevalent disease with 296 million people worldwide living with chronic hepatitis B virus (HBV) infections. Recent advances in HBV therapeutics have made infection a treatable disease, but they only disrupt certain areas of the HBV lifecycle. As a result, if the therapeutics are withdrawn, patients can relapse. What’s more, long-term use can cause antiviral resistance. To cure the disease, therapeutics need to address every stage of the HBV lifecycle, providing both seroclearance of the hepatitis B surface antigen (HBsAg) and silencing of the genomically integrated HBV DNA. However, investment in this space carries considerable risk as developers struggle to move treatments from animal models to human studies. Notably, human responses to HBV therapies are notoriously difficult to predict and traditional animal models translate poorly to the human environment, causing significant delays, as well as safety, cost, and efficacy concerns.

How can humanized liver models provide accurate efficacy measurements at each stage of the viral lifecycle? Hepatitis B is a serious global health threat. Around 1.5 million hepatitis B virus (HBV) infections were identified in 2019 alone and around 296 million people are thought to be living with the chronic disease.¹ Researchers are now targeting previously unexplored areas of the viral lifecycle to get closer to developing a complete cure.

In recent years, we have seen an explosion in the number of adeno-associated virus (AAV) vector-based gene therapies progressing to clinical trial stages, and subsequently an increasing number of regulatory successes. The reasons for this are clear. The versatility of AAV-based platforms makes them prime technology for targeting a range of tissues and pathologies, through their ability to silence, replace or modify genes.

Generating high-quality, pre-clinical data is always challenging, but it is especially so when developing therapeutics for hepatitis B and D. Since Hepatitis B Virus (HBV) and Hepatitis D Virus (HDV) only infect human hepatocytes, conventional animal models instantly pose a challenge as the entire viral lifecycle cannot be observed, and the data often doesn’t translate well to the human environment. These issues can lead to misleading metabolism, pharmacokinetics, efficacy and hepatotoxicity data, which can result in wasted time, money and resources and, potentially, failure at clinical trial stages.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in developed countries, with an estimated incidence of around 25% worldwide.

Rare Disease Day takes place on the last day of February each year since 2008. The main objective of Rare Disease Day is to raise awareness about rare diseases and the impact they have on lives.
