Interim analysis of 48-week tenofovir amibufenamide treatment in chronic hepatitis B patients with normal alanine aminotransferase levels
2025-08-19
(Press-News.org) Background and Aims
Chronic hepatitis B virus (HBV)-infected patients may exhibit liver fibrosis and other pathological changes despite normal alanine aminotransferase (ALT). This study aimed to assess the efficacy and safety of tenofovir amibufenamide (TMF) in chronic HBV-infected patients with normal ALT levels.
Methods
The ongoing PROMOTE study (NCT05797714) is the first prospective, multicenter, randomized, open-label, blank-controlled clinical trial involving chronic HBV-infected patients with normal ALT levels. Participants were randomized in a 1:1 ratio to receive either TMF (TMF group) or no treatment (blank control group). The primary efficacy endpoint was the proportion of participants achieving HBV DNA levels <20 IU/mL at 48 weeks.
Results
A total of 197 participants were enrolled, with 95 in the TMF group and 102 in the blank control group. At 48 weeks, a significantly greater proportion of participants in the TMF group achieved HBV DNA levels <20 IU/mL compared with the control group (74.2% vs. 9.0%, P < 0.001). The TMF group demonstrated more pronounced reductions in HBV DNA (−2.63 vs. −0.22 log10 IU/mL, P < 0.001), HBsAg (−0.07 vs. −0.04 log10 IU/mL, P = 0.02), and ALT levels (−14.09% vs. 0%, P = 0.003) compared with the blank control. In the TMF group, the proportion of participants with high-normal ALT levels (20–40 IU/L) was reduced. No significant differences were observed between the groups in creatinine, glomerular filtration rate, bone turnover biomarkers, lipid profiles, or phosphorus levels.
Conclusions
TMF treatment demonstrates significant efficacy in chronic HBV-infected patients with normal ALT levels and shows a favorable safety profile regarding bone, renal, and lipid parameters. The PROMOTE study is ongoing, and further results at 96 and 144 weeks are expected to provide additional insights.

Automated insulin delivery (AID) systems such as the UVA Health-developed artificial pancreas could help more type 1 diabetes patients if the devices become fully automated, according to a new review of the technology.
Even as the artificial pancreas and other AID systems have helped millions of people with type 1 diabetes better manage their blood sugar and improve their overall health, there are still limitations to overcome, according to the review from University of Virginia Center for Diabetes Technology scientists and their colleagues. These limitations include:
AID systems are not yet fully ...

West Nile virus (WNV) has been the dominant cause of mosquito-borne illness in the United States since its introduction into North America in 1999. There are no vaccines nor medications to prevent or treat illness in people, so surveillance, prevention, and control remain the best options to protect the public. Mosquito surveillance for WNV is a central component of the public health response, but this approach is labor intensive and limited by practical constraints on the number of locations that can be sampled. To address this limitation, Joseph McMillan and colleagues developed a validated machine learning model that uses freely ...

Sub-Saharan Africa currently has the highest infant mortality rate in the world, with 27 babies out of every 1,000 live births dying in their first month. As the climate warms, pregnant women in the region are increasingly exposed to extreme heat, which can cause reduced placental blood flow and dehydration, potentially affecting fetal development. In addition, extreme heat can lead to the proliferation of pathogenic bacteria in the environment, and can make it difficult for women to travel to prenatal care appointments. Jiafu An and colleagues sought to determine whether in-utero exposure to extreme ...

MINNEAPOLIS / ST. PAUL (08/19/2025) — Researchers at the University of Minnesota Twin Cities have made a groundbreaking discovery by observing and analyzing the first new type of plasma wave in Jupiter’s aurora. This research helps us understand “alien aurora” on other planets, which in turn teaches us more about how Earth’s magnetic field protects us from the sun’s harmful radiation.
The research is published in Physical Review Letters, a peer-reviewed, multidisciplinary, high-impact scientific journal.
The observation is based on data from NASA’s Juno spacecraft, which made a historic low ...

Stroke remains one of the leading causes of long-term disability worldwide, affecting millions each year. Among its most debilitating consequences is gait impairment, which affects over 80% of stroke survivors. Impaired walking not only reduces independence but also limits participation in daily and social activities, significantly diminishing the quality of life. While some patients regain partial ambulatory function, walking speed and coordination often remain impaired. Alarmingly, up to 22% of survivors never regain the ability to walk and are ...

Cerebrovascular diseases such as atherosclerosis and stroke remain a major cause of morbidity and mortality worldwide. A common feature of these diseases is vascular stenosis, i.e., the narrowing of blood vessels, which disrupts normal blood flow and contributes to chronic inflammation in the vessel wall. Endothelial cells lining the vasculature play a key role in sensing shear stress from blood flow and responding to disturbed hemodynamics by expressing pro-inflammatory molecules. However, studying this phenomenon in vivo is challenging due to the complexity ...

The tongue contains numerous taste buds—tiny sensory organs responsible for detecting taste. Taste buds consist of specialized cells that translate chemical stimuli into neural signals. Among them, type II cells, which respond to sweet, umami, and bitter stimuli, utilize channel-based signal transmission. In contrast, type III cells are believed to mediate sour signals via synaptic vesicle release. While the signaling mechanisms of type II cells are well-characterized, the process of vesicular synaptic transmission in type III cells is poorly understood.
Synaptic signal transmission relies on the SNARE complex, ...

Osaka, Japan－Researchers at The University of Osaka have discovered a new type of chiral symmetry breaking (CSB) in an organic crystalline compound. This phenomenon, involving a solid-state structural transition from an achiral to a chiral crystal, represents a significant advance in our understanding of chirality and offers a simplified model to study the origin of homochirality. This transformation also activates circularly polarized luminescence, enabling new optical materials with tunable light properties.
Chirality, or "handedness," is a fundamental property of objects, from galaxies to molecules, and plays a crucial role in biological ...

A newly developed system transforms human waste into a powerful tool for profitable and sustainable energy and agriculture in resource-limited regions. The prototype, outlined in a Stanford-led study published Aug 19 in Nature Water, recovers a valuable fertilizer from urine, using solar energy that can also provide power for other uses. In the process, the system provides essential sanitation, making wastewater safer to discharge or reuse for irrigation.
“This project is about turning a waste problem into a resource opportunity,” said study ...
