PURPOSE: Post-liver transplant(LT) patients with HCV are considered a difficult-to-treat population. Ledipasvir/sofosbuvir(LDV/SOF) +ribavirin(RBV) for 12 weeks is approved in GT1 LT recipients based on the SOLAR-1 & -2 data. However, patients are often treated with 8, 12 or 24 week regimens ± ribavirin. Recent reports have shown SVR rates achieved in clinical trials are similar to that observed in real-world datasets(RWD). The goal of this analysis is to compare efficacy rates in RWD to clinical trial data in this population.
METHODS: Integrated data on patients without cirrhosis or compensated cirrhosis post LT from 2 open-label phase-2 trials (SOLAR-1 and -2) were compared to 5 RWD. RWD were from academic institutions, community medical centers and specialty pharmacies. Cohorts with less than 50 patients treated with LDV/SOF+RBV were excluded. Demographics, safety data and SVR rates will be presented across cohorts.
RESULTS: In SOLAR-1 & -2, patients were assigned to receive LDV/SOF+RBV for 12 or 24 weeks, with SVR 12 rates 96%-98%. Patients from 5 RWD received LDV/SOF+RBV for 8, 12 or 24 weeks. SVR 12 in the 5 RWD ranged from 94-100%. RWD showed patients who received LDV/SOF without RBV had SVR rates of 94%-100% and those who received LDV/SOF with RBV had SVR12 rates of 96%-100%. Viral relapse rates were low, ranging from 1-2% across all RWD.
CONCLUSIONS: Evaluation of several RWD shows comparable SVR12 rates to clinical trials. Patients post-LT experience high cure rates of HCV with LDV/SOF+RBV. In addition, RWD showed RBV may not be needed in this population.
