What is the purpose of this trial?

This trial tests a combination of two treatments, CSG452 (also known as Tofogliflozin, a type of medication) and K-877-ER, to determine their effectiveness for Nonalcoholic steatohepatitis (NASH), a liver disease. Researchers aim to discover if these treatments together can improve liver health and reduce NASH symptoms. Participants will receive either one of the treatments, both, or a placebo (a substance with no therapeutic effect). This trial suits adults diagnosed with NASH who have specific characteristics in their liver biopsies. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. Please consult with the study team for guidance.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown that CSG452, an SGLT2 inhibitor, can improve liver health in people with non-alcoholic fatty liver disease (NAFLD). This medication is promising because it aids the liver without causing many side effects. Research indicates that these drugs do not lead to more negative side effects than usual.

For K-877-ER, specific safety information is limited, but it is being studied alongside CSG452 for potential benefits in treating liver diseases like nonalcoholic steatohepatitis (NASH). This study is in an early phase, and while initial tests suggest safety, further research is necessary.

Overall, both treatments are still under investigation, but early findings about their safety are encouraging. However, joining a trial always involves some risk, so discussing any concerns with the trial team is important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments, CSG452 and K-877-ER, for NASH (Non-Alcoholic Steatohepatitis) because they have a unique approach compared to the standard options like lifestyle changes, vitamin E, or pioglitazone. CSG452 and K-877-ER may work by targeting specific pathways involved in fat metabolism and inflammation, which are key factors in NASH progression. This targeted action could potentially slow down or even reverse liver damage more effectively than existing treatments. Additionally, K-877-ER may offer a novel mechanism by enhancing the removal of liver fat, which is a critical component in managing NASH. These innovative approaches provide hope for more effective management of this challenging condition.

What evidence suggests that this trial's treatments could be effective for NASH?

Studies have shown that CSG452, an SGLT2 inhibitor, can reduce liver fat and improve liver function. This is crucial for individuals with conditions like NASH, a liver disease characterized by fat accumulation. Research on similar drugs suggests they may help prevent liver damage. In this trial, some participants will receive CSG452 alone, while others will receive K-877-ER, another drug under investigation for its potential to improve liver health in people with NASH. Additionally, some participants will receive a combination of both CSG452 and K-877-ER, as early findings suggest that using these two drugs together might be even more effective in treating NASH. ^{1 6 7 8 9}

In a 24-month study involving 6,897 patients with type 2 diabetes, tofogliflozin was found to be safe and well-tolerated, with low incidence rates of adverse drug reactions (11.25%) and serious adverse reactions (1.21%).

Tofogliflozin significantly reduced glycated hemoglobin A1c by -0.70% and body weight by -2.95 kg, indicating its effectiveness in managing diabetes and promoting weight loss over the observation period.

Tofogliflozin, a medication for type 2 diabetes, showed no clinically significant changes in its pharmacokinetics across patients with normal to severe renal impairment, suggesting it is safe for use in these populations.

While renal impairment did lead to decreased urinary glucose excretion, which may affect glycemic control, the overall safety profile remained positive, indicating no need for dose adjustments in patients with renal issues.

Tofogliflozin, an oral medication for type 2 diabetes, was found to be rapidly absorbed and eliminated, with a dose-proportional increase in exposure up to 320 mg, indicating its effective pharmacokinetics in both Japanese and Caucasian subjects.

The drug was generally well tolerated with no serious adverse events or hypoglycemia reported, and it effectively increased urinary glucose excretion in a dose-dependent manner, suggesting its efficacy in managing blood sugar levels.

In the EFFECT-II study involving 84 participants with type 2 diabetes and non-alcoholic fatty liver disease (NAFLD), the combination of dapagliflozin and omega-3 carboxylic acids significantly reduced liver fat content by 21% compared to placebo, indicating a strong therapeutic effect.

Dapagliflozin alone also demonstrated a disease-modifying effect by reducing biomarkers of hepatocyte injury, suggesting it may help improve liver health in patients with NAFLD.

SGLT-2 inhibitors, tested in 12 randomized controlled trials involving 850 overweight or obese individuals with NAFLD, significantly reduced liver enzyme levels and liver fat content over a median treatment period of 24 weeks.

Specifically, treatment with SGLT-2 inhibitors led to a decrease in serum alanine aminotransferase by 10.0 IU/L and gamma-glutamyltransferase by 14.49 IU/L, indicating their potential efficacy in managing nonalcoholic fatty liver disease.

In a rodent model of non-alcoholic steatohepatitis (NASH), the SGLT2 inhibitor luseogliflozin significantly improved glucose levels and reduced liver damage caused by a high-fat diet, indicating its potential efficacy in treating NASH.

Luseogliflozin not only decreased liver weight gain and lipid accumulation but also normalized fibrotic changes and inflammatory responses in the liver, suggesting it could be a promising treatment for NASH associated with diabetes in humans.

In a study of 107 patients with nonalcoholic steatohepatitis (NASH), the 150 mg dose of licogliflozin resulted in a significant 32% reduction in serum alanine aminotransferase levels after 12 weeks, indicating its potential efficacy in treating NASH.

While licogliflozin was generally well-tolerated, diarrhea was reported in a majority of patients, particularly at the higher dose, suggesting that while the drug shows promise, its side effects need to be monitored in future studies.
