Ribavirin is a nucleoside analog that inhibits viral RNA-dependent RNA polymerase and depletes cellular guanosine pools, reducing viral replication. Together, they provide synergistic antiviral activity.","oneSentence":"Pegylated interferon alpha-2a activates innate immune responses against viral infection, while ribavirin inhibits viral RNA synthesis and replication.","_ai_confidence":"high"},"_scrapedAt":"2026-03-28T00:35:48.343Z","_scrapedBy":"cloudflare-swarm","_wikipedia":null,"indications":{"approved":[{"name":"Chronic hepatitis C virus infection"}]},"trialDetails":[{"nctId":"NCT01937728","phase":"PHASE4","title":"Tailored Regimens of PEGASYS® and Ribavirin for Genotype 1 Chronic Hepatitis C Patients Trial (TARGET-1)","status":"COMPLETED","sponsor":"Kaohsiung Medical University Chung-Ho Memorial Hospital","startDate":"2010-03","conditions":"Hepatitis C","enrollment":542}],"_emaApprovals":[],"_faersSignals":[],"_approvalHistory":[],"publicationCount":3,"rwe":[],"genericFilers":[],"relatedDrugs":[],"labelChanges":[],"biosimilarFilings":[],"pricing":[],"formularyStatus":[],"manufacturing":[],"companionDiagnostics":[],"competitors":[],"timeline":[],"patents":[],"ownershipHistory":[],"trials":[],"biosimilars":[],"latestUpdates":[],"references":[],"tags":[],"ecosystem":[],"genericManufacturerList":[],"offLabel":[],"developmentCodes":[],"aliases":["Pegasys, Robatrol"],"phase":"marketed","status":"active","brandName":"E: Peg-interferon alpha-2a & Ribavirin","genericName":"E: Peg-interferon alpha-2a & Ribavirin","companyName":"Kaohsiung Medical University Chung-Ho Memorial Hospital","companyId":"kaohsiung-medical-university-chung-ho-memorial-hospital","modality":"Small molecule","firstApprovalDate":"","aiSummary":"Peg-interferon alpha-2a and Ribavirin are used to treat Hepatitis C, as indicated by ClinicalTrials.gov.
