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

August 31, 2023 updated by: Prof. dr. Maria Prins, Public Health Service of Amsterdam
Men who have sex with men (MSM) who cured from hepatitis C virus (HCV) infection are at substantial risk of HCV reinfection. In this study, the investigators aim to evaluate the effectiveness of an online behavioural intervention, a home-based testing intervention and a combination of both on risk behaviour, and ultimately preventing HCV reinfection and onward spread of HCV.

Study Overview

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention I: behavioural intervention
Participants will receive the behavioural Intervention in addition to standard of care.
An online tailored behavioural intervention. The intervention will be developed as part of the project and will be based on the principles of the Information-Motivation-Behavioural Skills (IBM) model for behavioural change. It will consist of four interactive text-based modules, and demonstration and modelling videos addressing information, motivation, and behavioural skills. The intervention will be offered on a website and able to be used on PCs as well as any mobile device. It will be provided to the participants after randomization at month 6 and available for a total period of 18 months.
Experimental: Intervention II: home-based testing intervention
Participants will receive the home-based testing intervention in addition to standard of care.
An additional patient-initiated home-based HCV testing service. The service offers a maximum of 4 free-of-charge HCV-RNA tests, which involves HCV testing using self-sampled dried blood spots (DBS). The DBS obtained from a finger stick will be used for HCV-RNA testing in the laboratory. DBS test kits, along with instructions and package materials for returning the test kits with the self-collected DBS sample will be provided to the participants after randomization at month 6 and available for use for a total period of 18 months.
Experimental: Intervention III: combined intervention
Participants will receive the behavioural intervention and the home-based testing intervention in addition to standard of care.
An online tailored behavioural intervention. The intervention will be developed as part of the project and will be based on the principles of the Information-Motivation-Behavioural Skills (IBM) model for behavioural change.

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).
