Background
Clinical trials evaluating efficacy of direct-acting antiviral (DAA) therapies demonstrate sustained virologic response (SVR) rates greater than 90% in patients infected with hepatitis C (HCV) and human immunodeficiency virus (HIV). However, generalizability of this data to real-world coinfected populations is unknown.
Aim
We aim to compare efficacy data from clinical trials to effectiveness data of real-world observational studies that evaluate oral interferon-free HCV treatment regimens in patients infected with HIV and HCV.
Methods
We included English-language studies on PubMed and MEDLINE databases from inception until October 2017. Eight clinical trials and 11 observational studies reporting on efficacy data and effectiveness data, respectively, of interferon-free oral DAA regimens in HCV/HIV coinfected patients, were included.
Results
Of patients in the eight clinical trials evaluated, 93.1% (1218/1308) achieved SVR12; of the 11 real-world observational studies, 90.8% (2269/2499) achieved SVR12. Relative risk between those treated in clinical trials versus observational studies was 0.98. Patients with genotype 1 infection, African-American patients, cirrhotic patients, and patients with prior HCV treatment experience had similar rates of SVR in real-world and clinical trial cohorts.
Conclusion
SVR among real-world HCV/HIV coinfected populations treated with DAA regimens is similar to SVR of patients studied in clinical trials. Historically negative predictors of achieving SVR during the era of interferon-based treatments, such as those with cirrhosis, prior HCV treatment failure, GT1 infection, and African-American race, are not associated with a significantly lower SVR in real-world populations treated with various DAA regimens.
