Aims: Little is known about the safety and efficacy of LDV/SOF in patients with advanced chronic kidney disease (CKD) with eGFR ≤ 30 ml/min or on hemodialysis. Yet, off-label use of LDV/SOF in this population occurs. Methods: Providers proactively reporting such off-label use to Gilead Sciences were asked to submit de-identified case reports. Demographics, clinical characteristics at baseline, during, and after LDV/SOF treatment, and adverse events were collected. Summary statistics and paired sample t-tests are presented. Results: Twenty-one case summaries were submitted. Median Age was 59 (range 26-71). Eleven patients (52%) were black, 20 had genotype 1 (13-1a, 4-1b) and one patient had genotype 3. Median pretreatment viral load was 1,680,000 IU (range 133,000-37,200,000 IU). Twelve patients (56%) were on hemodialysis and 9 had CKD Stage 4 (eGFR 15-29 ml/min), 13 (62%) had cirrhosis, 11 (50%) had diabetes, 5 had history of organ transplantation (4 kidney, 1 liver). All patients received full dose LDV/SOF for 12 weeks with one patient also receiving 200 mg Ribavirin every other day in combination. Eight adverse events were reported; 2 patients (10%) with anemia, 1 case of insomnia, nausea/vomiting, headache, and chest pain (5%) each. Of the 9 patients with CKD stage 4, 2 experienced an increase in eGFR and 5 a decrease in eGFR post treatment. All 21 patients achieved SVR 12 (100%). No patient discontinued treatment due to an adverse event. Conclusions: In this small case series describing the use of ledipasvir/sofosbuvir in Patients with Advanced Chronic Kidney Disease: 62% had cirrhosis, 52% had diabetes mellitus, and 57% were on hemodialysis. All 21 patients achieved SVR12 including 12 patients on hemodialysis. LDV/SOF was relatively well tolerated and there were no treatment discontinuations. Most patients had stable renal function before and after treatment with LDV/SOF.

Aims: The optimal duration of therapy to achieve SVR depends on multiple factors. In a post-hoc analysis of the Phase 3 ION-3 (treatment-naive (TN), non-cirrhotic (NC) patients) 8 week of LDV/SOF data, a viral load (VL) <6M was shown to be the best predictor of SVR. Real world effectiveness (RWE) is often different from Phase III trials and there is a need to understand real-world 8 week regimens in a broader spectrum of patients. Methods: RWE 8 week LDV/SOF data is emerging from multiple single- center and multicenter retrospective and prospective cohorts. In this analysis, the phase-3 ION-3 data is compared with data from several diverse real world populations and one post-marketing investigator sponsored HIV/HCV trial. Patient demographics, characteristics, SVR12 and discontinuation data has been compared. Results: The ION-3 post-hoc analysis reported 123 patients who were TN, NC and VL<6M and treated with 8 weeks of LDV/SOF. Mean age was 52, 22% black, 72% GT1a; the SVR12 was 97% (119/123). The overall SVR12 rate from six diverse real world and post marketing cohorts was also 97% (638/658). There was no significant impact of HCV genotypes or subtypes (GT1a, 1b versus GT4), prior treatment history, presence or absence of cirrhosis, high viral load (HCV VL>6M), or HIV/HCV co-infection. All response rates are detailed in Figure1. Conclusions: LDV/SOF for 8 weeks yielded high SVR rates in ION-3. Analysis of RWE data from several diverse and heterogeneous cohorts from the US & EU show SVR outcomes that were consistent with the ION-3 results and supports the use of 8 weeks LDV/SOF in treatment- naive, non-cirrhotic GT1 patients with a baseline HCV VL <6M and possibly in other populations including HIV/HCV co-infected patients. Discontinuation rates were low despite diverse patients and clinical settings. Data from the TARGET and TRIO cohorts also suggests that the 8-week regimen is underutilized.
