Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hepatitis C is a common and potentially serious disease. However, there are treatments that can cure it. That's why it's so important to detect the hepatitis C virus (HCV) and treat those affected. Today, many hepatitis C sufferers in Cameroon (and elsewhere) remain untreated.

The aim of this research is therefore to evaluate a simplified screening and treatment strategy (developed specifically for the Cameroonian context) in comparison with a standard strategy (based on usual care), in order to improve access to hepatitis C treatment in Cameroon. If the results of this research are positive, this strategy could be recommended to health authorities in Cameroon and other comparable countries.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A two-arm, cluster-randomized, controlled trial will be conducted in blood banks and HIV clinics (the clusters) in the two largest cities in Cameroon (Yaoundé and Douala).

Persons aged 21 years or older, anti-HCV positive, and living in the study area will be eligible. The ACCESS+ strategy will rely on four components: (1) same-day on-site rapid anti-HCV and HCV RNA testing, (2) same-day on-site pan-genotypic DAA treatment initiation, (3) minimal clinical and biological monitoring, and (4) management by trained general medical doctors and counselors (community health workers, nurses or social workers) in non-specialist services. In contrast, in the standard strategy, the process for screening and treatment initiation will take longer, and anti-HCV positive participants will be managed by gastroenterologists and will have a closer follow-up.

Biological and clinical data (using standardized case report forms), socioeconomic data (using standardized questionnaires), and qualitative data (using interviews and focus groups) will be collected. A total of 576 anti-HCV positive participants (288 per arm) will be recruited in 16 facilities (8 blood banks and 8 HIV clinics) after testing approximately 32,000 blood donors and 8,400 patients living with HIV. The total duration of the trial will be 36 months.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ACCESS+ Strategy

ACCESS+ strategy will rely on four components:

1. same-day on-site rapid anti-HCV and HCV RNA testing,
2. same-day on-site pan-genotypic DAA treatment initiation,
3. minimal clinical and biological monitoring, and
4. management by trained general medical doctors and counselors (community health workers, nurses or social workers) in non-specialist services.

Group Type EXPERIMENTAL

ACCESS+ strategy Epclusa 400/100 Oral Tablet

Intervention Type DRUG

The ACCESS+ strategy will rely on four components: (1) same-day on-site rapid anti-HCV and HCV RNA testing (rapid diagnostic test and GeneXpert), (2) same-day on-site pan-genotypic DAA treatment initiation (sofosbuvir 400 mg/velpatasvir 100 mg once daily for 12 weeks), (3) minimal clinical and biological monitoring, and (4) management of patients in non-specialist services by trained general medical doctors and counselors (community health workers, nurses or social workers).

ACCESS+ Strategy Vosevi 400/100/100 Oral Tablet

Intervention Type DRUG

The ACCESS+ strategy will rely on four components: (1) same-day on-site rapid anti-HCV and HCV RNA testing (rapid diagnostic test and GeneXpert), (2) same-day on-site pan-genotypic DAA treatment initiation (sofosbuvir 400 mg/velpatasvir 100 mg/voxilaprevir 100mg) once daily for 12 weeks, (3) minimal clinical and biological monitoring, and (4) management of patients in non-specialist services by trained general medical doctors and counselors (community health workers, nurses or social workers).

Standard Strategy

In the standard strategy based on routine medical practice in Cameroon, anti-HCV positive participants will be referred to and managed by gastroenterologists, and the patients' management will be closer. However, the process for screening and treatment initiation will be longer.

Standard Strategy Vosevi 400/100/100 Oral Tablet

Intervention Type DRUG

In the standard strategy based on routine medical practice in Cameroon, anti-HCV positive participants will be referred to and managed by gastroenterologists who will initiate pan-genotypic DAA treatment initiation (sofosbuvir 400 mg/velpatasvir 100 mg/voxilaprevir 100mg) once daily for 12 weeks, and the patients' management will be closer. However, the process for screening and treatment initiation will be longer.
