Study to Describe the Actual Situation of Hepatitis C Treatment in Brazil

Completed

• Conditions: Hepatitis C Virus

• Registration Number: NCT02773394
• Lead Sponsor: Janssen-Cilag Ltd.

Brief Summary

The purpose of the study is to describe: 1) the clinical profile, past and current management of participants with hepatitis C in Brazil reference centers; 2) the current situation about demographics characteristics, liver disease progression and clinical outcomes in Brazilian Hepatitis C virus (HCV) participants naive, in treatment and previously exposed to antiviral treatment without sustained virological response (SVR).

Detailed Description

This is an observational, non-interventional, cross-sectional, multicenter study to describe demographic characteristics, treatment performed and clinical outcomes of Brazilian participants with HCV chronic infection in about 12 Brazilian reference centers. It will expect that approximately 2000 participants will be enrolled in the study. Analysis set will consist of participants with HCV chronic infection who are registered at the Brazilian reference centers and meet all the inclusion criteria and have sufficient information to identify the diagnosis of chronic HCV infection with identification of genotype. The study related data will be collected from the medical records in the predesigned electronic Case Report Form (eCRF).

Primary Outcome Measures

Name	Time	Method
Mode of Hepatitis C virus (HCV) transmission	Day 1	Data will be collected through medical records of the participants. Mode of HCV transmission route (unsafe injections, hemodialysis, infection drug use, blood transfusion, sexual transmission, vertical transmission, unknown, other) will be analysed by number of participants infected with HCV per transmission route.
Number of Participants with Coinfections	Day 1	Data will be collected through medical records of the participants.
HCV treatment status on Day 1: Number of participants treated without Sustained Virological Response (SVR)	Day 1	Data will be collected through medical records of the participants.
HCV genotype and subtype	Day 1	Data will be collected through medical records of the participants.
Number of participants with chronic hepatitis C infection	Day 1	Data will be collected through medical records of the participants.
Number of Participants with chronic hepatitis C infection Reported Based on City and States	Day 1	Data will be collected through medical records of the participants.
Number of Participants with chronic hepatitis C infection Based on precedence	Day 1	Data will be collected through medical records of the participants.
Number of participants with chronic hepatitis C infection Reported Based on Race	Day 1	Data will be collected through medical records of the participants.
Liver characteristics: Number of Participants with extra hepatic manifestations	Day 1	Data will be collected through medical records of the participants. Presence or absence of extra hepatic manifestations (cryoglobulinemia, lymphoma, Sjogren syndrome, glomerulopathy, Porphyria cutanea tarda, liquen planus, diabetes mellitus, thyroiditis, arthralgia).
Liver characteristics: Number of Participants with presence of comorbidities	Day 1	Data will be collected through medical records of the participants. Presence of comorbidities (amount of alcohol ingestion, metabolic syndrome, hepatocellular carcinoma, organ transplantation, diabetes, immunodeficiency, renal insufficiency and dialysis, use of drugs) will be collected.
Liver characteristics: Number of Participants with Fibrosis based on Fibroscan	Day 1	Data will be collected through medical records of the participants.
Treatment regimen	Day 1	The drugs used and time of treatment will be collected through medical records of the participants.
Date of last visit	Day 1
Mean Age of Participants with chronic hepatitis C infection	Day 1	Data will be collected through medical records of the participants.
Number of Males and Females with chronic hepatitis C infection	Day 1	Data will be collected through medical records of the participants.
Liver characteristics: Model for End-Stage Liver Disease (MELD) Score and Child Pugh score	Day 1	MELD is a scoring system for assessing the severity of chronic liver disease. Child-Pugh classification assesses the prognosis of chronic liver disease by 5 clinical measures, scored 1-3 each (most severe derangement=3). Score range: 5 (best prognosis) to 15 (worst prognosis).
HCV treatment status on Day 1: Percentage of participants receiving antiviral treatment	Day 1	Data will be collected through medical records of the participants.
HCV treatment status on Day 1: Causes of interruption in treatment	Day 1	Data will be collected through medical records of the participants. Causes of interruption to antiviral therapy will be collected and reported.
Number of participants with Adverse Events (AEs)	Day 1
Duration of diagnosis of chronic hepatitis C infection	Day 1	Data will be collected through medical records of the participants.
