Doyle,J (session presentation) ; coEC Study

Lu,Y (2 poster presentations) ; ASTRAL-5 Study

This presentation by J Doyle from the Burnet Institute highlighted the findings from the first year of the co-EC study in Melbourne. Modelling presented by Scott, et al at EASL 2017, proposes that treatment of 515 co-infected individuals in Victoria will reduce the prevalence of hepatitis C within the GBM community by 80%.


In the first year clinical data was collected on 160 chronic HIV/HepC co-infected individuals on ART. This included biochemical, haematological and fibrosis data. Primary care clinicians assessed this data and individuals either:

  • received immediate DAA therapy (40%)
  • received DAA therapy after specialist advice (31%)
  • were referred for specialist care (19%)

Referrals were predominantly required for known cirrhosis, APRI score >1, malignancy, renal/cardiac disease or fibroscan >12.5Kp.

This study highlighted the capacity for the majority of non-cirrhotic HIV/Hepatitis C individuals to be effectively managed by a primary care clinical team. This model of care fits comfortably with Australia's move toward patient centred, community based care within health care homes. 

ASTRAL-5 (2 poster presentations)

The efficacy, tolerability and safety of Sofosbuvir / Velpatasavir in HIV / Hep C co-infection was presented. 106 patients were enrolled for 12 weeks of SOF/VEL therapy. SVR at 12 weeks was demonstrated in the majority of patients across the 5 genotypical variants assessed. 

ASTRAL-5: SVR12 rates by genotype.

  •        Genotype                             SVR12%   (n/N)
  •        Total                                    95%
  •        GT1a                                    95%
  •        GT1b                                    92%
  •        GT2                                     100%
  •        GT3                                      92%
  •        GT4                                     100%

No patient experienced HIV virological rebound.

Side effects were similar to other available DAAs with fatigue (25%), headache (13%) and nausea (7%) reported. 

  • Drug-Drug interaction studies demonstrated no clinically significant interaction with a wide range of commonly used ART regimes. The only exception is that of EFV. There was a 53% reduction in VEL levels and thus EFV is currently not recommended for use with Velpatasvir. 

These presentations highlighted the suitability of primary care teams to effectively manage HIV/Hep C co-infection. This community based, patient centric model of care will enhance our capacity to eliminate Hepatitis C among the HIV cohort within Australia. The combination of Sofosbuvir with Velpatasvir provides pan-genotypical efficacy, good tolerability and limited drug interaction with ART. These characteristics will further enhance the ability of HIV/HepC to be safely and effectively managed in primary care settings within Australia.
