Safety of the 2D/3D direct-acting antiviral regimen in HCV-induced Child-Pugh A cirrhosis – A pooled analysis
Bibliographic record
Abstract
•OBV/PTV/r ± DSV ± RBV was well tolerated in patients with Child-Pugh A cirrhosis.•Low rates of serious adverse events and those leading to discontinuation of study drugs.•Events consistent with hepatic decompensation occurred in 1.2% of patients (13/1066).•Decompensation events occurred across the treatment period and post treatment.•Rates of decompensation events were comparable in treated and untreated patients. Background & AimsChronic hepatitis C virus (HCV)-infected patients with cirrhosis are a high-priority population for treatment. To help inform the benefit–risk profile of the all-oral direct-acting antiviral (DAA) combination regimen of ombitasvir, paritaprevir, and ritonavir, with or without dasabuvir (OBV/PTV/r ± DSV) in patients with Child-Pugh A cirrhosis, we undertook a comprehensive review of AbbVie-sponsored clinical trials enrolling patients with Child-Pugh A cirrhosis.MethodsTwelve phase II or III clinical trials of the 2-DAA regimen of OBV/PTV/r ± ribavirin (RBV) or the 3-DAA regimen of OBV/PTV/r + DSV ± RBV that included patients with Child-Pugh A cirrhosis were reviewed; patients who completed treatment by November 16, 2015 were included in a pooled, post hoc safety assessment. The number and percentage of patients with treatment-emergent adverse events (TEAEs), serious TEAEs, and TEAEs consistent with hepatic decompensation were reported.ResultsIn 1,066 patients with Child-Pugh A cirrhosis, rates of serious TEAEs and TEAEs leading to study drug discontinuation were 5.3% (95% confidence interval [CI]: 4.1–6.8) and 2.2% (95% CI: 1.4–3.2), respectively. Thirteen patients (1.2%; 95% CI: 0.7–2.1) had a TEAE that was consistent with hepatic decompensation. The most frequent TEAEs consistent with hepatic decompensation were ascites (n = 8), esophageal variceal hemorrhage (n = 4), and hepatic encephalopathy (n = 2).ConclusionsThis pooled analysis in 1,066 HCV-infected patients with Child-Pugh A cirrhosis confirms the safety of OBV/PTV/r ± DSV ± RBV in this population. These results support the use of OBV/PTV/r ± DSV ± RBV in this high-priority population.Lay summary: This pooled safety analysis in 1,066 HCV-infected patients with compensated cirrhosis, receiving treatment with ombitasvir, paritaprevir, and ritonavir with or without dasabuvir, with or without ribavirin, shows that the rate of hepatic decompensation events was similar to previously reported rates in untreated patients. Chronic hepatitis C virus (HCV)-infected patients with cirrhosis are a high-priority population for treatment. To help inform the benefit–risk profile of the all-oral direct-acting antiviral (DAA) combination regimen of ombitasvir, paritaprevir, and ritonavir, with or without dasabuvir (OBV/PTV/r ± DSV) in patients with Child-Pugh A cirrhosis, we undertook a comprehensive review of AbbVie-sponsored clinical trials enrolling patients with Child-Pugh A cirrhosis. Twelve phase II or III clinical trials of the 2-DAA regimen of OBV/PTV/r ± ribavirin (RBV) or the 3-DAA regimen of OBV/PTV/r + DSV ± RBV that included patients with Child-Pugh A cirrhosis were reviewed; patients who completed treatment by November 16, 2015 were included in a pooled, post hoc safety assessment. The number and percentage of patients with treatment-emergent adverse events (TEAEs), serious TEAEs, and TEAEs consistent with hepatic decompensation were reported. In 1,066 patients with Child-Pugh A cirrhosis, rates of serious TEAEs and TEAEs leading to study drug discontinuation were 5.3% (95% confidence interval [CI]: 4.1–6.8) and 2.2% (95% CI: 1.4–3.2), respectively. Thirteen patients (1.2%; 95% CI: 0.7–2.1) had a TEAE that was consistent with hepatic decompensation. The most frequent TEAEs consistent with hepatic decompensation were ascites (n = 8), esophageal variceal hemorrhage (n = 4), and hepatic encephalopathy (n = 2). This pooled analysis in 1,066 HCV-infected patients with Child-Pugh A cirrhosis confirms the safety of OBV/PTV/r ± DSV ± RBV in this population. These results support the use of OBV/PTV/r ± DSV ± RBV in this high-priority population.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
