Aim: In the PEMA-FL study in patients with metabolic dysfunction-associated steatotic liver disease (MASLD), pemafibrate was shown to significantly decrease low-density lipoprotein cholesterol (LDL-C) levels. We aimed to investigate the mechanisms of pemafibrate-induced LDL-C reduction in patients with MASLD by conducting an additional sub-analysis of the PEMA-FL study.

Methods: The PEMA-FL study randomized 118 patients with MASLD to receive pemafibrate or placebo for 72 weeks.

Aims: Efficacy, safety, and pharmacokinetics of the selective PPARα modulator pemafibrate as once-daily extended-release (XR) tablets were compared with those of twice-daily immediate-release (IR) tablets in patients with hypertriglyceridemia.

Methods: A multicenter, randomized, single-blind, active-controlled crossover, phase 2 clinical pharmacology study was performed in patients with hypertriglyceridemia. Patients were randomly assigned to IR 0.

Aims: Pemafibrate substantially lowers serum triglyceride (TG) levels and increases high-density lipoprotein cholesterol (HDL-C) levels primarily in Japan, but it has not been evaluated in China. We aimed to confirm the efficacy and safety of pemafibrate in Chinese patients with hypertriglyceridemia and low HDL-C levels by comparing placebo and fenofibrate.

Methods: A multicenter, double-masked trial was conducted in China involving 344 patients with high TG and low HDL-C levels randomly assigned to one of four groups: pemafibrate 0.

Elevated triglyceride levels are associated with an increased risk of cardiovascular events despite guideline-based statin treatment of low-density lipoprotein cholesterol. Peroxisome proliferator-activated receptor α (PPARα) agonists exert a significant triglyceride-lowering effect. However, combination therapy of PPARα agonists with statins poses an increased risk of rhabdomyolysis, which is rare but a major concern of the combination therapy.

Aims: Pemafibrate, a selective peroxisome proliferator-activated receptor α modulator that lowers serum triglyceride levels and increases high-density lipoprotein cholesterol levels, is approved for treating dyslipidemia as twice-daily immediate-release (IR) tablets. A once-daily extended-release (XR) tablet has also been developed. We aimed to confirm the non-inferiority of XR (0.

Background: Ivermectin is an antiparasitic drug administered to hundreds of millions of people worldwide. Fundamental research suggests that ivermectin is effective against coronavirus disease 2019 (COVID-19); therefore, we investigated the efficacy and safety of ivermectin as a COVID-19 treatment option.

Methods: This multi-regional (Japan and Thailand), multicenter, placebo-controlled, randomized, double-blind, parallel-group, Phase III study evaluated the efficacy and safety of ivermectin in patients with mild COVID-19 (IVERMILCO Study).

Aim: Ezetimibe administration with ongoing statin therapy is an effective option for further lowering low-density lipoprotein cholesterol (LDL-C) levels. Thus, we investigated the long-term efficacy and safety of fixed-dose combination of pitavastatin/ezetimibe (K-924 LD: 2 mg/10 mg; K-924 HD: 4 mg/10 mg).

Methods: We conducted a phase III, multicenter, open-label trial involving patients with hypercholesterolemia receiving pitavastatin (2 or 4 mg) who had not achieved their LDL-C management target.

Aim: We compared the efficacy and safety of pitavastatin/ezetimibe fixed-dose combination with those of pitavastatin monotherapy in patients with hypercholesterolemia.

Methods: This trial was a multicenter, randomized, double-blind, active-controlled, parallel-group trial. A total of 293 patients were randomly assigned into four groups receiving 2 mg pitavastatin, 4 mg pitavastatin, 2 mg pitavastatin/10 mg ezetimibe (K-924 LD), and 4 mg pitavastatin/10 mg ezetimibe (K-924 HD) once daily for 12 weeks.

Background: Pemafibrate is a novel, selective peroxisome proliferator-activated receptor α modulator (SPPARMα). In mice, Pemafibrate improved the histological features of non-alcoholic steatohepatitis (NASH). In patients with dyslipidaemia, it improved serum alanine aminotransferase (ALT).

Background: Risk-based monitoring (RBM) is a slow uptake in some trial sponsors. There are three main reasons for this. First, there is the fear of making large investments into advanced RBM technology solutions.

The levels of transcripts of the cpc operon were highly reduced in a PD-1 mutant of cyanobacterium Synechocystis sp. strain PCC 6714. This was due to a substitution of C for T that occurred at 5 bp upstream of the transcription initiation site of the cpc operon.

The transcription factor NtcA is a global regulator of nitrogen homeostasis in cyanobacteria. It thus positively regulates the expression of genes related to nitrogen assimilation such as glnA (which encodes glutamine synthetase) and ntcA itself in response to nitrogen shortage or depletion. The binding of NtcA to the glnA and ntcA promoters of Synechococcus sp.
