CHARISMA Expansion Study (CHARISMA)
Community Health Clinic Model for Agency in Relationships and Safer Microbicide Adherence (CHARISMA) Expansion Study
The CHARISMA Expansion Study is a two-arm, randomized (1:1), controlled study of a behavioral intervention-the Community Health clinic model for Agency in Relationships and Safer Microbicide Adherence (CHARISMA)-to reduce social harms (SHs) and intimate partner violence (IPV), increase healthy relationship dynamics and oral PrEP (pre-exposure prophylaxis) TDF/FTC (tenofovir disoproxil fumarate/emtricitabine), hereafter called PrEP, adherence among enrolled women. This study is an expansion of the CHARISMA intervention pilot study which was appended to the Microbicide Trials Network (MTN)-025 HOPE (HIV Open Label Prevention Extension) study.
CHARISMA is defined by the use of a tool, called the CHARISMA HEAlthy Relationship Assessment Tool (HEART) used in combination with three counselling modules:
- Module A: General Partner Communication and Relationship Skills
- Module B: Partner Disclosure and Communication around PrEP Use
- Module C: Responding to Intimate Partner Violence and Safety Planning

Detailed Description
The CHARISMA Expansion Study is a two-arm, randomized (1:1), controlled study of a behavioral intervention-the Community Health clinic model for Agency in Relationships and Safer Microbicide Adherence (CHARISMA)-which aims to reduce social harms (SHs) and intimate partner violence (IPV), increase healthy relationship dynamics and oral PrEP TDF/FTC (hereafter called PrEP) adherence among enrolled women. This study is an expansion of the CHARISMA intervention pilot study which was appended to the Microbicide Trials Network (MTN)-025 HOPE study and will conclude in 2018.
CHARISMA is defined by the use of a tool, called the CHARISMA HEAlthy Relationship Assessment Tool (HEART) used in combination with three counselling modules:
- Module A: General Partner Communication and Relationship Skills
- Module B: Partner Disclosure and Communication around PrEP Use
- Module C: Responding to Intimate Partner Violence and Safety Planning
The HEART will be used to assess the status of women's relationships and experience of IPV in the intervention arm. The HEART, previously piloted in HOPE, is a tool used to facilitate assessment of, and response to, the range of positive and negative effects of HIV prevention product use experienced by women in intimate partner relationships.
In September 2015, the World Health Organization issued guidelines recommending PrEP be offered to all persons at substantial HIV risk (defined as HIV incidence rate above 3%) worldwide. In sub-Saharan Africa, women account for 58% of the total number of people living with HIV. Given the high HIV incidence and evidence for high potential effectiveness of PrEP when adherence to product use is high, PrEP delivery, adherence, and associated male partner dynamics should be evaluated among a broad age range of women.
This study will enroll sexually active, HIV-uninfected women, who are trial naïve, non-pregnant and aged 18-45 years (inclusive). PrEP, delivered according to national guidelines, IPV screening using the WHO Violence Against Women Survey (VAWS) and referrals for care will be offered to all eligible participants as Standard of Care (SOC) in the control arm. CHARISMA intervention arm participants will receive in-person counselling as part of the CHARISMA intervention to help them assess and build support for PrEP use within their relationships. SHs, IPV, relationship dynamics (e.g. communication, support) and PrEP adherence will be compared across the two arms. Social harms are defined as non-clinical trial related adverse events that result in psychosocial, social, or physical harm among women.
Design: Two-arm, randomized (1:1), controlled study of a behavioral intervention to increase adherence to daily oral PrEP, improve partner relationships (communication and support) and reduce SH and IPV.
A PrEP delivery project will be established in accordance with national guidelines in South African Department of Health (DoH) PrEP guidelines supplemented by the addition of the CHARISMA intervention. Participants presenting for enrolment will be randomized to one of two study arms below:
- Control: Standard of care (SOC) HIV prevention services in line with the South African DoH PrEP rollout program that include daily oral TDF/FTC. In addition, risk reduction counseling, IPV screening using the VAWS with referrals for counseling, medical care, or shelter assistance, among other care options if needed and an informational packet regarding HIV prevention services for themselves and male partners will be offered;
CHARISMA Intervention: SOC per control arm plus provider-administration of HEART and provider-administration of CHARISMA counseling modules, as applicable:
- Module A: General Partner Communication and Relationship Skills
- Module B: Partner Disclosure and Communication around PrEP Use
- Module C: Responding to Intimate Partner Violence and Safety Planning
Population: Approximately four hundred sexually active, HIV-uninfected women who are trial naïve, non-pregnant, and not planning to be pregnant for the next six months, non-breastfeeding, aged 18 to 45 years of age (inclusive)
Study Site(s): Wits RHI (Reproductive Health and HIV Institute) Clinical Research Site, Johannesburg, South Africa Other site(s) to be determined
Approach: This project will offer a PrEP delivery package within two arms of a controlled, randomized study of women to evaluate the impact of the CHARISMA intervention when paired with PrEP delivery.
Study Duration: Accrual will require approximately 12 months. Each participant presenting for PrEP education and services will be enrolled and followed for 6 months. Participants in both study arms will participate in scheduled visits for screening, enrollment, and months 1, 3, and 6 of follow-up. A subset of participants will be asked to participate in a qualitative interview at month 6, and/or month 9.
Primary Objectives:
- To determine the effectiveness of the CHARISMA intervention in increasing PrEP adherence/persistence at month 6;
- To determine the effectiveness of the CHARISMA intervention in reducing reported experiences of social harms while on PrEP;
- To determine the effectiveness of the CHARISMA intervention in reducing reported experiences of IPV (irrespective of time on PrEP);
To determine the effectiveness of CHARISMA on participant's reported relationship dynamics, including disclosure of PrEP use, support for product use, and communication;
Secondary Objective:
- To explore the acceptability and feasibility of the CHARISMA intervention; and
Exploratory Objective:
7) To assess the sensitivity and specificity of a brief IPV screening tool compared to a longer validated tool in identifying cases of IPV.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
PrEP adherence/persistence by measurement
Time Frame: 3 months
|
Adherence will be ascertained through measurement of TFV-DP (tenofovir-diphosphate) in dried blood spot (DBS) specimens.
DBS collected via blood draw at Month 3 and 6 follow-up visits will be used for retrospective PCR testing for tenofovir levels (although DBS is collected at Enrollment and Month 1 as well).
|
3 months
|
PrEP adherence/persistence by measurement
Time Frame: 6 months
|
Adherence will be ascertained through measurement of TFV-DP in DBS specimens.
DBS collected via blood draw at Month 3 and 6 follow-up visits will be used for retrospective PCR testing for tenofovir levels (although DBS is collected at Enrollment and Month 1 as well).
|
6 months
|
PrEP adherence/persistence by self-report
Time Frame: 3 months
|
Self-reported data on PrEP adherence will be collected via standardized questionnaires to better understand patterns of PrEP use and reasons for poor adherence or discontinuation.
The tool used for the assessment is the WHO Violence Against Women Survey (VAWS).
VAWS consists of behavior-specific items related to psychological (four items), physical (six items) and sexual violence (three items).
The physical violence items are further divided into 'moderate' (the two first items) and 'severe' (the following four items) violence based on the likelihood of physical injury.
Values are considered worse as responses to experiences of violence increase from no=0, to one=1, few=2, and many=3 times.

Incidence of social harms (SHs) using a SHs questionnaire
Time Frame: Anytime during the study, up to 6 months
|
SH in this study could include negative consequences related to study participation, PrEP use disclosure, stigma, gender-based violence, and relationship problems.
Participants will be screened for SH resulting from product use or study participation at Enrollment, Month 3, and Month 6, and may report a social harm to staff at any time during the study.
|
Anytime during the study, up to 6 months
|
IPV: Self-report of a) any IPV or b) physical or sexual IPV during study participation.
Time Frame: Anytime during the study, up to 6 months
|
All participants will receive SOC IPV screening at enrollment and at the Month 3 and Month 6 visits and may report IPV to staff at any time during the study.
