Phase 3 RCT: Resmetirom Significantly Improves NASH Resolution and Liver Fibrosis
16 Nov, 2024 | 13:56h | UTCBackground: Nonalcoholic steatohepatitis (NASH) is a progressive liver disease with no approved treatments. It significantly increases the risk of liver-related complications, especially in patients with type 2 diabetes. Resmetirom, a thyroid hormone receptor beta-selective agonist, is being investigated for its potential to treat NASH and liver fibrosis.
Objective: To evaluate the efficacy and safety of resmetirom in resolving NASH and improving fibrosis in adults with biopsy-confirmed NASH and fibrosis stages F1B to F3.
Methods: This double-blind, placebo-controlled phase 3 trial randomized 966 adults with NASH to receive once-daily resmetirom (80 mg or 100 mg) or placebo for 52 weeks. Primary endpoints included (1) NASH resolution with no fibrosis worsening and (2) fibrosis improvement by at least one stage without NAFLD activity score worsening. Secondary outcomes included changes in lipid profiles and liver biomarkers.
Results: At 52 weeks, NASH resolution occurred in 25.9% of patients receiving 80 mg and 29.9% receiving 100 mg of resmetirom, compared with 9.7% in the placebo group (P<0.001 for both doses vs. placebo). Fibrosis improved by at least one stage in 24.2% (80 mg) and 25.9% (100 mg) of resmetirom-treated patients versus 14.2% for placebo (P<0.001). LDL cholesterol reductions were −13.6% (80 mg) and −16.3% (100 mg) at 24 weeks versus 0.1% for placebo (P<0.001). Improvements were also noted in triglycerides, liver enzymes, and imaging biomarkers. Adverse events, primarily mild gastrointestinal symptoms, were more frequent with resmetirom. Serious adverse events were similar across groups (10.9%–12.7%).
Conclusions: Resmetirom significantly improved NASH resolution and fibrosis compared to placebo, demonstrating its potential as a treatment for NASH with liver fibrosis.
Implications for Practice: Resmetirom offers a promising treatment option for NASH, potentially altering the disease course and improving outcomes. Clinicians should monitor for regulatory approval and long-term safety data.
Study Strengths and Limitations: Strengths include robust biopsy-confirmed endpoints and a large sample size. Limitations include short follow-up and lack of clinical-outcome data.
Future Research: Long-term studies are needed to assess durability, safety, and effects on clinical outcomes like cirrhosis and liver-related mortality.
Cohort Study: GIP/GLP-1 Receptor Agonist Prescriptions Linked to Reduced Opioid Overdose and Alcohol Intoxication
20 Oct, 2024 | 18:36h | UTCBackground: Opioid use disorder (OUD) and alcohol use disorder (AUD) are prevalent conditions leading to significant morbidity and mortality, including overdose and intoxication. Current pharmacotherapies for OUD and AUD are underutilized due to barriers like access and stigma. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), used for type 2 diabetes and obesity, have shown potential in modulating reward pathways associated with substance use, suggesting a possible role in reducing substance-related harms.
Objective: To estimate the association between prescriptions of glucose-dependent insulinotropic polypeptide (GIP) and/or GLP-1 receptor agonists and the incidence of opioid overdose and alcohol intoxication in patients with OUD and AUD, respectively, and to assess this association among patients with comorbid type 2 diabetes and obesity.
Methods: This retrospective cohort study analyzed de-identified electronic health record data from 136 U.S. health systems in the Oracle Cerner Real-World Data, covering over 100 million patients from January 2014 to September 2022. Adults aged 18 years or older with a history of OUD (n = 503,747) or AUD (n = 817,309) were included. The exposure was defined as having one or more prescriptions of GIP/GLP-1 RAs after the first OUD or AUD diagnosis. The primary outcomes were the incidence rates of opioid overdose in the OUD cohort and alcohol intoxication in the AUD cohort.
Results: Patients with GIP/GLP-1 RA prescriptions had significantly lower rates of opioid overdose (aIRR in OUD patients: 0.60; 95% CI, 0.43–0.83) and alcohol intoxication (aIRR in AUD patients: 0.50; 95% CI, 0.40–0.63) compared to those without such prescriptions. The protective association remained significant among patients with comorbid type 2 diabetes and obesity.
Conclusions: Prescriptions of GIP and/or GLP-1 receptor agonists are associated with lower rates of opioid overdose and alcohol intoxication in patients with OUD and AUD. These protective effects persist across various subgroups, including those with comorbid type 2 diabetes and obesity.
Implications for Practice: GLP-1 RAs show promise for reducing substance-related harms in patients with OUD and AUD. Clinicians may consider the potential benefits of GIP/GLP-1 RA prescriptions in this population, while recognizing the need for further research to establish causality and understand underlying mechanisms.
Study Strengths and Limitations: Strengths include a large, diverse patient population and adjustment for multiple confounders. Limitations involve the retrospective observational design limiting causal inference and reliance on data from Cerner-affiliated health systems, which may affect generalizability.
Future Research: Prospective clinical trials are needed to validate these findings, elucidate underlying mechanisms, and assess the efficacy and safety of GIP/GLP-1 RAs as treatments for substance use disorders.
RCT: Granulocyte Colony-Stimulating Factor (GCSF) Enhances 90-Day Survival and Reduces Complications in Severe Alcohol-Associated Hepatitis
20 Oct, 2024 | 17:23h | UTCStudy Design and Population: This randomized trial evaluated 126 patients with severe alcohol-associated hepatitis (SAH) eligible for steroid treatment, with discriminant function scores between 32 and 90. Patients were randomized into three groups: prednisolone alone, GCSF alone, and combined GCSF plus prednisolone (GPred). Prednisolone was administered at 40 mg/day, while GCSF was given at 150-300 mcg/d for 7 days, then every third day for up to 12 doses over a month.
Main Findings: The GPred group showed significantly higher 90-day survival (88.1%) compared to prednisolone alone (64.3%, P = 0.03) and GCSF alone (78.6%). The 28-day survival was similar across groups. The GPred group also had more steroid responders by day 7 and showed greater improvements in discriminant function and MELDNa scores. Additionally, patients in the GPred group had significantly lower rates of infections, acute kidney injury, hepatic encephalopathy, and rehospitalizations.
Implications for Practice: Adding GCSF to prednisolone improves survival and reduces the risk of infections and complications in patients with severe alcohol-associated hepatitis. This combination therapy could be considered for improving outcomes in steroid-eligible patients with SAH.
Management of Ascites in Cirrhosis: Key Recommendations from the British Society of Gastroenterology Guidelines
12 Oct, 2024 | 18:23h | UTCIntroduction: Ascites, the pathological accumulation of fluid within the peritoneal cavity, is a common and serious complication of cirrhosis, indicating advanced liver disease and portending increased morbidity and mortality. Recognizing the need for updated clinical guidance, the British Society of Gastroenterology (BSG), in collaboration with the British Association for the Study of the Liver (BASL), has issued comprehensive guidelines. These aim to standardize the diagnosis and management of ascites in cirrhotic patients, incorporating recent advances to optimize patient outcomes.
Key Recommendations:
- Diagnostic Paracentesis: It is strongly recommended that all patients with new-onset ascites undergo diagnostic paracentesis to measure total protein concentration and calculate the serum-ascites albumin gradient (SAAG). (Quality of evidence: moderate; Recommendation: strong)
- Spontaneous Bacterial Peritonitis (SBP): Prompt diagnostic paracentesis should be performed in hospitalized patients with ascites, especially those with gastrointestinal bleeding or signs of infection, to rule out SBP. An ascitic neutrophil count >250/mm³ confirms SBP, necessitating immediate empirical antibiotic therapy tailored to local resistance patterns. (Quality of evidence: moderate; Recommendation: strong)
- Dietary Salt Restriction: Patients should restrict dietary sodium intake to no more than 5–6.5 grams per day (87–113 mmol), equivalent to a no-added-salt diet, to manage fluid accumulation effectively. (Quality of evidence: moderate; Recommendation: strong)
- Diuretic Therapy: For initial moderate ascites, spironolactone monotherapy is recommended. In cases of recurrent severe ascites, combination therapy with spironolactone and furosemide is advised. Regular monitoring for adverse events such as electrolyte imbalances and renal impairment is essential. (Quality of evidence: moderate; Recommendation: strong)
- Large Volume Paracentesis (LVP): LVP is a safe and effective treatment for refractory ascites. Informed consent is required, and routine coagulation studies or prophylactic blood product infusions before the procedure are not recommended. (Quality of evidence: moderate; Recommendation: strong)
- Use of Human Albumin Solution (HAS): After LVP exceeding 5 liters, infusion of HAS at 8 grams per liter of ascites removed is strongly recommended to prevent circulatory dysfunction. (Quality of evidence: high; Recommendation: strong)
- Transjugular Intrahepatic Portosystemic Shunt (TIPSS): TIPSS should be considered for patients with refractory ascites not responding to medical therapy, with caution exercised in patients over 70 years or those with significant comorbidities. (Quality of evidence: high; Recommendation: strong)
- Non-Selective Beta-Blockers (NSBBs): The presence of refractory ascites is not a contraindication for NSBB therapy. Patients should be closely monitored, and dose adjustments made in cases of hypotension or renal dysfunction. (Quality of evidence: moderate; Recommendation: strong)
- Palliative Care: Patients unsuitable for liver transplantation should be offered palliative care referral to focus on symptom management and quality of life improvement. Alternative interventions for refractory ascites may also be considered. (Quality of evidence: weak; Recommendation: strong)
Conclusion: Implementation of these evidence-based guidelines is expected to enhance patient care by promoting early diagnosis, preventing complications, and standardizing management strategies for ascites in cirrhosis. Adherence to these recommendations can improve clinical outcomes, reduce hospitalizations, and enhance the quality of life for affected patients.
RCT: Tirzepatide Significantly Improves MASH Resolution Without Worsening Fibrosis Over 52 Weeks – N Engl J Med
10 Aug, 2024 | 19:53h | UTCStudy Design and Population: This phase 2, multicenter, double-blind, randomized, placebo-controlled trial evaluated the efficacy and safety of tirzepatide in 190 participants with biopsy-confirmed metabolic dysfunction-associated steatohepatitis (MASH) and moderate to severe liver fibrosis (stage F2 or F3). Participants were assigned to receive subcutaneous tirzepatide (5 mg, 10 mg, or 15 mg) or placebo weekly for 52 weeks.
Main Findings: Tirzepatide significantly improved MASH resolution without worsening fibrosis compared to placebo. Resolution rates were 44% for 5 mg, 56% for 10 mg, and 62% for 15 mg, versus 10% for placebo. Improvement in fibrosis stage without worsening MASH was also higher in tirzepatide groups (51-55%) than in the placebo group (30%). The most common adverse events were mild to moderate gastrointestinal symptoms.
Implications for Practice: Tirzepatide shows promise as a treatment for MASH with moderate to severe fibrosis, significantly improving disease resolution without worsening fibrosis. However, further research with larger and longer trials is needed to confirm these findings and evaluate long-term safety.
Phase 2 Trial: Survodutide Improves MASH Without Worsening Fibrosis, But Increases GI Side Effects – N Engl J Med
10 Aug, 2024 | 19:47h | UTCStudy Design and Population: This 48-week, phase 2 randomized trial evaluated the efficacy and safety of survodutide, a dual agonist of the glucagon and GLP-1 receptors, in 293 adults with biopsy-confirmed metabolic dysfunction-associated steatohepatitis (MASH) and fibrosis (F1-F3 stages). Participants were randomized to receive weekly injections of survodutide (2.4, 4.8, or 6.0 mg) or placebo.
Main Findings: Survodutide significantly improved MASH without worsening fibrosis compared to placebo, with 47% to 62% of participants in the survodutide groups achieving histologic improvement versus 14% in the placebo group. A reduction in liver fat content by at least 30% was observed in 57% to 67% of participants receiving survodutide, compared to 14% in the placebo group. However, adverse events such as nausea, diarrhea, and vomiting were more common with survodutide.
Implications for Practice: The findings suggest that survodutide could be a promising treatment for MASH, with potential benefits for liver histology and fat content. However, the increased gastrointestinal side effects warrant careful consideration in future phase 3 trials to better evaluate the drug’s safety profile and long-term efficacy.
Phase 2 RCT: Low-dose aspirin significantly reduces hepatic fat in MASLD patients without cirrhosis
20 Mar, 2024 | 17:48h | UTCStudy Design and Population: This phase 2, randomized, double-blind, placebo-controlled clinical trial was carried out over six months at a single hospital in Boston, Massachusetts. The study included 80 participants aged 18 to 70 years diagnosed with metabolic dysfunction–associated steatotic liver disease (MASLD) but without cirrhosis. Participants were randomly assigned to receive either 81 mg of daily aspirin (n=40) or placebo (n=40).
Main Findings: The trial revealed that aspirin significantly reduced the mean absolute change in hepatic fat content by -10.2% compared with placebo, as measured by proton magnetic resonance spectroscopy (MRS), with a statistically significant difference (P=0.009). Furthermore, aspirin treatment notably decreased relative hepatic fat content, increased the proportion of patients achieving a 30% or greater reduction in hepatic fat, and reduced both absolute and relative hepatic fat content as assessed by magnetic resonance imaging proton density fat fraction (MRI-PDFF). Adverse events were mostly minor, with upper respiratory infections and arthralgias being the most common.
Implications for Practice: These findings suggest that low-dose aspirin may be an effective intervention for reducing liver fat in adults with MASLD without cirrhosis, potentially offering a simple, accessible treatment option. However, the results are preliminary and call for further confirmation in larger, more diverse populations. The study underscores the importance of considering low-dose aspirin as part of management strategies for MASLD, pending further research.

Phase 2 RCT | FGF21 analogue Pegozafermin treatment leads to improvement in NASH fibrosis
30 Jun, 2023 | 14:58h | UTCSummary: In a phase 2b, multicenter, double-blind, randomized, placebo-controlled trial, the fibroblast growth factor 21 (FGF21) analogue pegozafermin was examined for its efficacy and safety in treating patients with biopsy-confirmed noncirrhotic nonalcoholic steatohepatitis (NASH). A total of 222 patients with moderate or severe fibrosis (stage F2 or F3) were assigned to receive either subcutaneous pegozafermin at varying doses or a placebo. The primary endpoints were an improvement in fibrosis and resolution of NASH without worsening of fibrosis at 24 weeks.
The results showed that a larger percentage of patients receiving pegozafermin met the criteria for fibrosis improvement and NASH resolution compared to those receiving placebo. The most significant improvements were observed in the 44-mg pegozafermin group, with 27% showing fibrosis improvement and 26% meeting NASH resolution criteria, compared to 7% and 2% in the placebo group, respectively. Adverse events were mainly gastrointestinal and included nausea and diarrhea. These findings support the progression of pegozafermin into phase 3 development.

RCT | Bulevirtide reduces HDV RNA and ALT levels in chronic hepatitis D patients
28 Jun, 2023 | 13:20h | UTCSummary: This randomized phase 3 trial evaluated the efficacy of bulevirtide, an inhibitor of HDV entry into hepatocytes, in patients with chronic hepatitis D. Patients were randomized to receive either 2 mg or 10 mg of bulevirtide daily for 144 weeks, or no treatment for 48 weeks followed by 10 mg bulevirtide daily for 96 weeks. The study involved 150 patients, 49 in the 2-mg group, 50 in the 10-mg group, and 51 in the control group.
After 48 weeks of treatment, 45% and 48% of patients in the 2-mg and 10-mg groups respectively achieved the primary end point of undetectable HDV RNA level or a decrease of at least 2 log10 IU per milliliter from baseline, and normalization of ALT level. Only 2% in the control group reached the primary endpoint. ALT levels normalized in 51% and 56% of patients in the 2-mg and 10-mg groups respectively, a significant difference from the 12% normalization in the control group. Notably, loss of HBsAg did not occur by week 48 in the bulevirtide groups. No serious adverse events related to the treatment were reported, though side effects including headache, pruritus, and fatigue were more common in the bulevirtide groups.
These results demonstrate the effectiveness of bulevirtide in reducing HDV RNA and ALT levels in patients with chronic hepatitis D. However, the absence of HBsAg loss in bulevirtide groups raises questions about its long-term implications.
