Simeprevir (TMC435) With Pegylated Interferon/Ribavirin in Patients Coinfected With HCV Genotype 1 and HIV-1: A Phase 3 Study
Bibliographic record
Abstract
BACKGROUND: Simeprevir is an oral, once-daily, hepatitis C virus (HCV) NS3/4A protease inhibitor for the treatment of chronic HCV genotype 1 infection. Human immunodeficiency virus (HIV) coinfection accelerates progression of liver disease. This uncontrolled, open-label trial explored the safety and efficacy of simeprevir in patients with HCV genotype 1/HIV type 1 (HIV-1) coinfection. METHODS: Patients received simeprevir (150 mg once daily) with pegylated interferon alfa-2a/ribavirin (peg-IFN/RBV) for 12 weeks. Noncirrhotic HCV treatment-naive patients and prior relapsers received response-guided therapy (RGT) with peg-IFN/RBV for 24 or 48 weeks. Prior null responders, prior partial responders, and patients with cirrhosis received peg-IFN/RBV for 48 weeks. The primary endpoint was sustained virologic response 12 weeks after the end of treatment (SVR12). RESULTS: One hundred and six patients (93 on antiretroviral therapy) were enrolled and treated. SVR12 rates were 79.2% in HCV treatment-naive patients, 57.1% in prior null responders, 86.7% in prior relapsers, and 70.0% in prior partial responders. Fifty-four of 61 eligible patients (88.5%) met RGT criteria for 24 weeks of peg-IFN/RBV, of whom 87.0% (47/54) achieved SVR12. SVR12 rates were 80.0% (36/45) and 63.6% (14/22) for patients with METAVIR scores of F0-F2 and F3-F4, respectively. Common adverse event (AE) rates were consistent with peg-IFN/RBV therapy (fatigue, headache, nausea, neutropenia). Most AEs were grade 1/2; serious AEs occurred in 5.7% of patients, none of which were fatal. CONCLUSIONS: Simeprevir was generally well tolerated with safety similar to that observed in HCV-monoinfected patients and high SVR12 rates in HCV treatment-naive patients, prior relapsers, prior partial responders, and prior null responders with HIV-1 coinfection.

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.
