Glecaprevir/Pibrentasvir

MAVIRET® (glecaprevir/pibrentasvir) is now approved in the European Union for the treatment of acute hepatitis C virus (HCV) infection with compensated liver disease (with or without cirrhosis) in adults and children aged 3 years and older. The approval gives clinicians an option to initiate treatment as soon as acute infection is confirmed, aiming to reduce delays in care and lower the risk of liver disease progression, cirrhosis and liver cancer. As the only treatment approved in the EU for both acute and chronic HCV infection, MAVIRET may help streamline care pathways and support broader efforts to advance HCV elimination goals. NORTH CHICAGO, Ill., June 23, 2026 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that the European Commission approved MAVIRET® (glecaprevir/pibrentasvir), an oral pangenotypic direct-acting antiviral (DAA) therapy for the treatment of acute hepatitis C virus (HCV) infection in adults and children aged 3 years and older. With this approval, MAVIRET is now the only treatment approved in the European Union for both acute and chronic HCV infection. "More than 12 million people in Europe live with hepatitis C, underscoring the need for earlier treatment," said Roopal Thakkar, M.D., executive vice president, research and development, chief scientific officer, AbbVie. "Today's European Commission approval of MAVIRET for acute hepatitis C infection enables earlier intervention, aiming to help more people access curative therapy at the time of diagnosis, while accelerating progress toward the goal of eliminating hepatitis C as a public health threat." HCV is a highly infectious blood-borne disease that often goes undetected because people may not show symptoms.1 While HCV is curable, many people remain undiagnosed.1 If left untreated, HCV can progress to severe liver complications, including cirrhosis and end-stage liver disease.1 Current clinical guidance supports treating nearly all people with acute or chronic HCV infection.2 "People living with HCV infection frequently face delayed treatment, leading to loss to care and onward transmission," said Massimo Puoti, MD, director of the Infectious Diseases Department at Niguarda Hospital in Milan, Italy. "With this approval, healthcare professionals across the European Union now have an approved treatment option to treat patients at the earliest stage of infection, supporting prompt intervention and helping to reduce transmission, disease progression, and long-term complications for people living with hepatitis C." Globally, HCV poses a substantial health and economic burden3, with over 200,000 deaths each year from liver cancer.1 People living with HCV are up to 17 times more likely to develop liver cancer than those unaffected.4 The approval was supported by data from the Phase 3, multicenter, single-arm prospective study evaluating the safety and efficacy of MAVIRET eight-week treatment regimen in patients with acute HCV infection.5 The study results showed MAVIRET to be a highly efficacious treatment for people with acute HCV.5 The majority of the adverse events reported were mild or moderate in severity.5 The most common adverse events were fatigue, diarrhea, headache, and asthenia.5 AbbVie continues to collaborate with global regulatory authorities to support access to MAVIRET for people living with acute HCV infection. MAVIRET is approved in the United States, Saudi Arabia, New Zealand, Canada, Taiwan, Australia and Argentina for the treatment of acute and chronic HCV infection in adults and children aged 3 years and older. About the Phase 3 M20-350 Study 5 The multicenter, single-arm prospective Phase 3 M20-350 clinical trial was designed to evaluate the safety and efficacy of MAVIRET (glecaprevir/pibrentasvir) eight-week treatment in adults and adolescent participants aged 12 years and older with acute HCV infection. The study enrolled 286 treatment-naïve adult patients with acute HCV infection across 70 locations globally. Patients received oral tablets of MAVIRET once daily for eight weeks and were followed for 12 weeks after the end of treatment. The primary endpoint was the percentage of patients with sustained virological response 12 weeks post-treatment (SVR12) in the intent-to-treat population (ITT). The study met its primary endpoint, with 96.2% of patients in the ITT population achieving SVR12 (p<0.0001). The key secondary endpoint was also met with 100% of patients in the modified ITT-Virologic Failure population achieving SVR12 (p<0.0001). No on-treatment virologic failures or post-treatment relapses were observed, and post-treatment reinfection occurred in 0.7% of patients. The overall safety profile observed in the M20-350 study was similar to that observed in patients with chronic HCV infection. No serious adverse reactions or adverse reactions leading to treatment discontinuation that were judged as treatment-related were observed among patients with acute HCV infection. The most commonly reported adverse reactions were fatigue (3%), asthenia (2%), headache (2%), and diarrhea (2%). More information on the study can be found at (NCT04903626). About MAVIRET® (glecaprevir/pibrentasvir) MAVIRET® (glecaprevir/pibrentasvir) is an oral, pangenotypic, once-daily, ribavirin-free direct-acting antiviral treatment for acute and chronic hepatitis C virus (HCV) infection in adults and children 3 years and older. MAVIRET combines glecaprevir, an NS3/4A protease inhibitor, and pibrentasvir, an NS5A inhibitor, and is administered once daily with food. In the European Union, MAVIRET is approved for the treatment of acute and chronic HCV infection in adults and children aged 3 years and older. Important EU Safety Information: CONTRAINDICATIONS: MAVIRET is contraindicated in patients with severe hepatic impairment (Child-Pugh C). Concomitant use of MAVIRET is contraindicated with atazanavir-containing products, atorvastatin, simvastatin, dabigatran etexilate, ethinyl oestradiol-containing products, strong P-gp and CYP3A inducers (e.g., rifampicin, carbamazepine, St. John's wort [Hypericum perforatum], phenobarbital, phenytoin, and primidone). SPECIAL WARNINGS AND PRECAUTIONS FOR USE: Hepatitis B virus reactivation Cases of hepatitis B virus (HBV) reactivation, some of them fatal, have been reported during or after treatment with direct-acting antiviral agents. HBV screening should be performed in all patients before initiation of treatment. HBV/HCV co-infected patients are at risk of HBV reactivation, and should, therefore, be monitored and managed according to current clinical guidelines. Hepatic impairment MAVIRET is not recommended in patients with moderate hepatic impairment (Child-Pugh B). Patients who failed a prior regimen containing an NS5A and/or an NS3/4A inhibitor MAVIRET is not recommended for the re-treatment of patients with prior exposure to NS3/4A and/or NS5A inhibitors. Use in diabetic patients Patients with diabetes may experience improved glucose control and potential symptomatic hypoglycaemia after initiating HCV direct-acting antiviral treatment. Glucose levels should be closely monitored, particularly within the first 3 months of treatment. ADVERSE REACTIONS In pooled Phase 2 and 3 clinical studies of adult subjects receiving MAVIRET with genotype 1, 2, 3, 4, 5 or 6 chronic HCV infection the most commonly reported adverse reactions were headache and fatigue. In a Phase 3b clinical study of adult subjects receiving MAVIRET with genotype 1, 2, 3, or 4 acute HCV infection the most commonly reported adverse reactions were fatigue, asthenia, headache and diarrhoea.

The European Commission has approved Maviret (glecaprevir/pibrentasvir) for the treatment of acute hepatitis C virus (HCV) infection, making it the only therapy in the EU authorized for both acute and chronic HCV. The label expansion, granted to AbbVie, covers adults and children aged 3 years and older without cirrhosis or with compensated cirrhosis. The clinical significance lies partly in timing: acute HCV is frequently asymptomatic, meaning patients are often diagnosed incidentally and may progress to chronic infection before treatment begins. Enabling treatment at the acute stage could reduce onward transmission and limit long-term liver complications. Maviret combines two direct-acting antivirals: glecaprevir, an NS3/4A protease inhibitor discovered by Massachusetts-based Enanta Pharmaceuticals (Nasdaq: ENTA) under a collaboration with AbbVie that dates back to 2006, and pibrentasvir, an NS5A inhibitor. Together, they target distinct steps in viral replication, providing pangenotypic activity across all major HCV genotypes. The approved regimen is administered as an oral, once-daily fixed-dose combination for eight weeks. The approval was supported by the Phase III M20-350 study (NCT04903626), a multicenter, single-arm prospective trial enrolling 286 treatment-naïve adults with acute HCV infection across 70 sites globally. The primary endpoint was sustained virological response 12 weeks post-treatment (SVR12) in the intent-to-treat population. SVR12 was achieved in 96.2% of patients (p\<0.0001); in the modified intent-to-treat virologic failure population, 100% achieved SVR12. No on-treatment virologic failures or post-treatment relapses were reported, and the safety profile was consistent with that observed in chronic HCV studies. By inhibiting both NS3/4A protease and NS5A — proteins essential for viral polyprotein processing and replication complex assembly — the combination exerts complementary pressure on the virus, reducing the likelihood of resistance emergence. The pangenotypic profile is particularly relevant in the acute setting, where genotype testing may not yet be available at the time of diagnosis. Although direct-acting antivirals have transformed chronic HCV treatment, uncertainty around whether and when to treat acute infection has historically led some clinicians to defer therapy until chronic infection is established. The new indication formally supports treatment earlier in the disease course. Maviret was already approved in the EU for chronic HCV and faces competition from sofosbuvir-based regimens, including sofosbuvir/velpatasvir (Epclusa, Gilead Sciences), which also carries pangenotypic activity but does not hold an EU approval specifically for acute HCV infection. The new indication therefore establishes a differentiated position for Maviret in the acute treatment setting, where earlier intervention is increasingly supported by clinical guidelines from the European Association for the Study of the Liver.
