Treatment for Hepatitis C
For chronic Hepatitis C, use pangenotypic direct-acting antiviral (DAA) regimens as first-line therapy, with sofosbuvir/velpatasvir for 12 weeks being the preferred option for most patients regardless of genotype, treatment history, or presence of compensated cirrhosis. 1
First-Line Treatment Regimens
The following pangenotypic DAA combinations are recommended based on the most recent guidelines:
Preferred Regimens (All Genotypes)
Sofosbuvir/velpatasvir: 12 weeks for all genotypes (1-6), treatment-naïve or treatment-experienced patients, with or without compensated cirrhosis, no ribavirin needed 2, 1
Glecaprevir/pibrentasvir: 8 weeks for non-cirrhotic patients; 12 weeks for compensated cirrhosis 2, 1, 3
Ledipasvir/sofosbuvir: 12 weeks for genotype 1,4,5, or 6 (can be shortened to 8 weeks in treatment-naïve, non-cirrhotic patients with baseline HCV RNA <6 million IU/mL) 2, 1, 4
Elbasvir/grazoprevir: 12 weeks for genotype 1 or 4 (requires absence of NS5A resistance-associated substitutions for genotype 1a) 2, 1
Genotype-Specific Considerations
Genotype 1
- All pangenotypic regimens listed above are highly effective 2
- Real-world data confirms 95-98% SVR rates with ledipasvir/sofosbuvir 5, 6, 7
- Eight-week ledipasvir/sofosbuvir is appropriate for treatment-naïve, non-cirrhotic patients with HCV RNA <6 million IU/mL 1, 5, 6
Genotype 2
Genotype 3
- Sofosbuvir/velpatasvir for 12 weeks (treatment-naïve without cirrhosis) 2
- Add ribavirin or extend to 24 weeks for treatment-experienced or cirrhotic patients 2
- Glecaprevir/pibrentasvir: 8 weeks (non-cirrhotic), 12 weeks (cirrhotic), or 16 weeks (treatment-experienced) 2
Genotype 4
- Ledipasvir/sofosbuvir, elbasvir/grazoprevir, glecaprevir/pibrentasvir, or sofosbuvir/velpatasvir all for 12 weeks 2
Genotypes 5 and 6
- Ledipasvir/sofosbuvir or sofosbuvir/velpatasvir for 12 weeks 2
Special Populations
Compensated Cirrhosis (Child-Pugh A)
- Most regimens require 12-week duration 2, 1
- Glecaprevir/pibrentasvir: 12 weeks 2, 1
- Sofosbuvir/velpatasvir: 12 weeks 2
- Consider adding ribavirin for genotype 3 2
Decompensated Cirrhosis
- Ledipasvir/sofosbuvir plus ribavirin for 12 weeks 1
- Sofosbuvir/velpatasvir plus ribavirin for 12 weeks 1
- Avoid glecaprevir/pibrentasvir in decompensated cirrhosis 3
HIV/HCV Coinfection
- Use same regimens and durations as HCV monoinfection 2
- Sofosbuvir/velpatasvir achieves 92-95% SVR in coinfected patients 2
Patients on Rifampicin (TB Treatment)
- Glecaprevir/pibrentasvir is preferred due to lack of significant drug interactions 3
- Daclatasvir plus sofosbuvir is an alternative 3
- Monitor liver function weekly if AST/ALT ≥2× normal; consider stopping both medications if AST/ALT ≥5× normal or bilirubin rises 3
Monitoring During Treatment
- Measure HCV RNA at baseline, week 4, week 12, end of treatment, and 12-24 weeks post-treatment 1
- Sustained virologic response (SVR12) is defined as undetectable HCV RNA 12 weeks after treatment completion and represents virological cure 1
Critical Warnings and Contraindications
Hepatitis B Reactivation
- Test all patients for HBsAg and anti-HBc before starting HCV treatment 4
- HBV reactivation can cause fulminant hepatitis, hepatic failure, and death 4
- Monitor HCV/HBV coinfected patients during and after treatment 4
Drug Interactions
- Avoid amiodarone with sofosbuvir-containing regimens due to risk of serious symptomatic bradycardia, particularly with concurrent beta-blockers or in patients with cardiac comorbidities 4
- Avoid P-glycoprotein inducers (rifampin, St. John's wort, carbamazepine) with most DAA regimens 4
- Proton pump inhibitors reduce efficacy of ledipasvir/sofosbuvir; consider modification or discontinuation 5
Common Pitfalls to Avoid
- Do not use 8-week ledipasvir/sofosbuvir in cirrhotic patients, treatment-experienced patients, or those with baseline HCV RNA ≥6 million IU/mL 1, 4
- Do not delay treatment waiting for genotype results when pangenotypic regimens are available 1
- Real-world data shows only 44% of eligible patients received appropriate 8-week therapy, suggesting underutilization of shorter regimens 5
- Baseline NS5A resistance testing is generally not required, as modern regimens achieve high SVR even with resistance-associated substitutions 8
