Interventions to Curb Hepatitis C Reinfections Among Men Who Have Sex With Men (ICECREAM)
Study Overview

Intervention / Treatment
Detailed Description
Rationale: As highly effective therapy against hepatitis C virus (HCV) infection is available with rapid uptake, there is newfound optimism for HCV elimination. Nevertheless, HCV reinfections cause great concern in at risk populations, including men who have sex with men (MSM). In the Netherlands, MSM account for the majority of new HCV (re)infections. Although HCV treatment uptake is high in this group, modelling data indicate HCV elimination would not be feasible without a reduction in risk behaviour. This finding highlights the urgent need for effective interventions aimed at reducing risk behaviour and preventing reinfections in MSM.
Objective: To evaluate interventions aimed at reducing risk behaviour, and ultimately preventing HCV reinfections and onward spread of HCV.
Study design: Using a 3-arm randomised trial comparing run-in and intervention periods, we will evaluate the effect of two interventions and its combination on risk behaviour in MSM previously infected with HCV.
Study population: MSM aged 18 years or older with a history of a successfully treated or spontaneously cleared HCV infection.
Interventions: Intervention I is a targeted, online behavioural intervention developed as part of the project. Intervention II aims to increase the frequency of testing by offering an additional patient-initiated, home-based HCV RNA testing service with the use of self-sampled dried blot spots. Intervention III is a combination of intervention I and II.
Study parameters/endpoints: From run-in and post-randomization questionnaires, we will evaluate the proportion at risk of HCV infection (as determined by the HCV-MOSAIC score) as the primary outcome. The HCV-MOSAIC risk score is calculated by summing up the beta coefficients specific to six self-reported risk factors when present: receptive condomless anal sex (beta 1.1), sharing sex toys (beta 1.2), unprotected fisting (beta 0.9), injecting drug use (beta 1.4), sharing straws during nasally-administered drug use (beta 1.0), and ulcerative sexually transmitted infection (beta 1.4). Secondary outcomes include incidence of HCV reinfection, changes in the individual risk behaviour items and changes in sexual wellbeing.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in the proportion at risk for HCV infection (as determined by a HCV-MOSAIC risk ≥ 2.0).
Time Frame: Run-in period (0-6 months) versus intervention period (6-24 months)
|
From run-in and post-randomization questionnaires, we will evaluate the proportion at risk of HCV infection (as determined by a HCV-MOSAIC score ≥ 2.0) during the run-in versus intervention periods.
The HCV-MOSAIC risk score has been previously validated for acute HCV-infection and is calculated by summing up the beta-coefficients specific to six self-reported risk factors when present in the past 6 months: (i) receptive condomless anal sex (beta 1.1), (ii) sharing sex toys (beta 1.2), (iii) unprotected fisting (beta 0.9), (iv) injecting drug use (beta 1.4), (v) sharing snoring equipment during nasally-administered drug use (beta 1.0), and (vi) ulcerative sexually transmitted infection (beta 1.4).
