30 de abril de 2026 atualizado por: Duke University

Combating Related Epidemics in HCV Through Simplified Testing and Treatment. A Cluster Randomized Trial of Point-of-care Hepatitis C Testing and Treatment Among Key Populations

This is a two-arm cluster randomized control trial to evaluate the effectiveness of a single-visit point-of-care (POC) test and treat bundle (intervention arm) compared to the current standard-of-care (SOC, control arm). 1:1 randomization occurs at the site level.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Comparador Ativo: Standard of Care (control arm)
Participants will complete standard local clinical practice for HCV, HIV, and HBV testing and for initiation of treatment of HCV.
Participants with detectable HCV RNA on Xpert test will receive sofosbuvir/velpatasvir at the same visit as the POC test in the intervention arm. Participants in the SOC arm will receive sofosbuvir/velpatasvir after standard of care testing and treatment assessment has been completed.
Outros nomes:
  • Direct acting antiviral
Experimental: Single-visit POC test & treat (intervention arm)
Sites randomized to the single-visit point-of-care test (POC) & treat arm will undergo fingerstick POC HCV RNA, HIV antibody/antigen, and HBsAg and for those with detectable HCV RNA, HCV treatment will be initiated.
Participants with detectable HCV RNA on Xpert test will receive sofosbuvir/velpatasvir at the same visit as the POC test in the intervention arm. Participants in the SOC arm will receive sofosbuvir/velpatasvir after standard of care testing and treatment assessment has been completed.
Outros nomes:
  • Direct acting antiviral
Cepheid Xpert HCV Test, performed on the GeneXpert Xpress system, in an automated in vitro reverse transcription polymerase chain reaction (RT-PCR) test for the qualitative detection of Hep C (HCV) RNA in human fingerstick.
Abbott Determine HIV - 1/2 Ag/Ab combo is an in vitro, visually read, qualitative immunoassay for the simultaneous detection of Human Immunodeficiency Virus type-1 (HIV-1) p24 antigen (Ag) and antibodies (Ab) to HIV type-1 and type-2 in fingerstick. Intended use is point-of-care test to aid in the diagnosis of infection.
Determine HBsAg 2 is an in vitro, visually read, qualitative immunoassay for detection of Hepatitis B Surface Antigen (HBsAg) in human fingerstick. The test is intended as an aid to detect HBAg from infected individuals.
