- What is the purpose of renewing and expanding WIHS?
The purpose of renewing the WIHS is to continue support for pathogenesis, virology, epidemiologic outcomes, and comparative effectiveness research in a representative cohort of U.S. women. The specific goals of WIHS-V are to continue characterizing the long-term, natural and treated history of HIV infection, and by recruiting and retaining new women into the cohort, provide insight into the changing demographics of the HIV-1 epidemic among women in the U.S. In addition, WIHS will move to a rolling cohort design whereby new women will be enrolled to account for prior cohort members who are later lost to follow-up.
WIHS is a unique global resource because it includes a comparable control group of HIV seronegative women, is a source of information on highly characterized, rare phenotypes, is a study of predominately minority women, and documents co-morbidities faced by women that are not well represented in other clinical studies. Evaluations performed in the WIHS go beyond clinical care and includes assessments of long-term outcomes in the era of effective antiretroviral therapy, in-depth interviewer administered questionnaires, comprehensive physical and gynecologic examinations, ascertainment of HIV- and related health care, and provides clinical and laboratory data linked to a high quality repository of stored samples. Enrolling more women to the study in WIHS-V, and accounting for women lost to follow-up, will better reflect current treatment practices, and is crucial in order to maintain study power and relevance to U.S. HIV epidemic in women.
- What institutions are eligible to apply?
The current WIHS clinical grantee institutions are eligible to apply to the WIHS-V FOA. In addition, applications will be accepted from institutions with the capacity to enroll the target populations of HIV-positive and HIV-negative but at risk women from the Southern region of the U.S. (Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, or Texas only). The current WDMAC is eligible to submit a renewal application as the data management and analysis center in response to the WIHS-V FOA. Applications for the WIHS data management and analysis center will be accepted only from the current WDMAC.
- What are the enrollment criteria for women to be recruited in WIHS-V?
Existing WIHS CRSs may propose to recruit up to 100 new HIV+ and HIV- women at the site during the period covered by WIHS-V. Applicant institutions for a new Southern U.S. CRS may recruit 200-300 HIV+ and HIV- women. The goal of WIHS-V is to recruit around 1,000 new women (250 HIV+ recent HAART initiators, 250 HIV+ HAART naïve, and 500 HIV-negative matching the age distribution of HIV+ women). While all applicants should describe their enrollment plans, the final determination of the specific sample sizes and enrollment criteria for existing and the new Southern U.S. CRSs will be determined by NIH and the WIHS EC after consultation with the WIHS External Advisory Board. In general the target strata at each CRS may differ by age, race, documented previous use of anti-HIV medications, and clinical health history as determined from medical record abstraction. A focus will include ensuring that the most at-risk HIV-negative women are targeted for enrollment in addition to enrolling HIV+ women. Having access to consistent clinical care is not an inclusion requirement for enrollment to the current WIHS, and documenting the disassociation of WIHS participants from HIV and related clinical care is a key element to understanding the true epidemiology of HIV among women. However, all WIHS CRS applications should describe how the site facilitates access to clinical care for all enrollees. WIHS will also move to a rolling cohort, and successful CRSs should anticipate replacing women who become lost to follow-up during the period of WIHS-V.
- For the purposes of the WIHS-V FOA, what is a Clinical Research Site vs Clinical Site?
All WIHS-V clinical applicants must submit proposals to serve as a WIHS CRS. The CRS is responsible for not only adhering to the standard WIHS data and specimen collection protocols, and recruiting and retaining the target population of women in WIHS, but also must carry out a scientific agenda of research that is either limited to the applicant organization (and collaborators) or extended WIHS-wide. While each application should be distinct, all WIHS-V applicants must demonstrate integration of a proposed “local” research agenda into the larger WIHS cohort goals. Only those applications that propose outstanding research, as deemed by the outcome of the peer review process, will be eligible to receive funding as a CRS. Applicant budgets are expected to include project costs to carry out local and WIHS-wide scientific goals using the local population. However, it is acceptable to also mention, albeit not budget, the costs for which support would be required to extend such projects to other WIHS CRSs. In addition, because resources are limited for the WDMAC to perform all conceivable WIHS analyses, budgets associated with local and WIHS-wide scientific agendas can include costs for local statistical and analytic support to carry out the research plans.
In order to balance the WIHS cohort geographically and maintain the sample sizes to address study objectives on long-term outcomes, NIAID may choose to continue funding one or more existing WIHS CRSs as a Clinical Site (CS). A CS will be responsible for adhering to the standard WIHS data and specimen collection protocols, and recruiting and retaining the target population of women in WIHS. The decision to fund a site at the CS level will be made based on the outcome of the peer review process, with funding to be based on per-patient cost negotiated between the institution and NIAID prior to issuing an award. The new Southern U.S. CRS must be competitive at the CRS level in order to receive funding.
- Is the scope of the WDMAC expected to change in WIHS-V?
No. No additional activities are expected that are beyond the current scope of the WDMAC in supporting the WIHS Consortium. Sufficient resources will be provided for the WDMAC to maintain existing central functions as well as fully integrate the new Southern CRS into processes necessary to routinely access standardized WIHS core and substudy protocols; manuals of operation; source documents, informed consent templates, and data collection forms; web-based communication and document storage tools; central data management and reporting systems; programmer consultation and analytic support at WDMAC for EC-approved projects; committee conference calls and meetings, and prepare for data audit site visits.
- Are Multiple Principal Investigator (MPI) applications allowed?
Yes, MPI applications are highly encouraged for CRS and the WDMAC applications. Meritorious MPI applications for a CRS would include a team with diverse expertise in clinical infectious diseases and HIV epidemiology. Applications for the new Southern CRS can include MPIs from one or more institutions within the Southern states of interest listed in the FOA but must have access to patient populations from one or more of these Southern states.
Current WIHS CRS awardees are not eligible to submit applications proposing either single or MPI leadership for the new Southern CRS. However, existing CRS awardees may be included as collaborators in applications proposed for the new Southern CRS.
- What is the page limit for the Research Strategy section? Are there requirements specific to this FOA that will be included in the scored criteria?
All applicant organizations can submit a response to the WIHS-V FOA that includes a maximum of 30 pages for the Research Strategy Section of the SF-424. This is the only exception for this FOA; all other page limits for U01 applications must be followed: http://grants.nih.gov/grants/forms_page_limits.htm. In addition to standard criteria, additional WIHS-specific element are included in the scored review criteria for the WIHS-V FOA. All applicants should be sure to thoroughly review all elements in “Section V, Application Review Information “ of the FOA.
- What are the qualifications for the clinical health practitioners who will perform the physical examinations each study visit?
Healthcare practitioners who perform the required WIHS physical examinations can include physicians, nurse practitioners, and physician assistants. However, all study practitioners must be certified and state licensed. In addition, as documented by the WDMAC, study practitioners must complete the required WIHS physical examination training process and must maintain routine proficiency assessments in following study procedures.
- Will training be required for WIHS study interviewers?
Yes, WIHS study interviewers must complete the required, centralized interview training process managed by the WDMAC and must maintain routine proficiency assessments in following study procedures.
- Are there additional requirements for public use data access and data sharing?
All clinical and laboratory data collected by WIHS sites become part of the overall WIHS database (each CRS submits patient visit and testing results on a regular basis to WDMAC via a Web-based system). In turn, WDMAC returns datasets to the sites after data curation is completed. The most current WIHS clinical and laboratory data are made available to internal and external collaborators through the “concept sheet” mechanism, which can be accessed on the public WIHS website. All applicants to the WIHS-V FOA should describe how site investigators will adhere to WIHS concept sheet and publication policies. All CRS and the WDMAC applicants should describe how data from local research will be made available to the internal WIHS and external research investigators.
All WIHS-V applications must include a plan describing how data documentation and sharing will be accomplished within one year after data collection, as well as appropriate safeguards to protect patient privacy implemented at the national WIHS level. In addition, all applications should describe any current ethical and/or logistical challenges to full data sharing and how the CRS or WDMAC intends to overcome or remediate such conflicts.
As a reminder that in accordance with NIH Data Sharing policies, the WDMAC is responsible for the annual creation of a WIHS public-use data (PUD) electronic file covering the data collection period up to 18 months before the file's creation. All collected variables must be provided in a widely useable format with appropriate, complete data dictionaries to accompany the data. This compilation of de-identified data is released for public use each year, and is available for purchase from the National Technical Information Service.
- What types of comparative effectiveness research will be allowed?
Proven health interventions that do not require Investigational New Drug (IND) applications and are of low risk to participants will be allowed in WIHS-V. These include, but are not limited to research on: Smoking cessation, alcohol and/or drug abuse interventions; amelioration of depression or depressive symptoms; measures to improve ARV adherence; exercise regimens for weight loss, to reduce toxicity, and/or impact HIV-related frailty; measures to improve cervical and other cancer screening.
- How do I find information about the groups with whom WIHS collaborates?
The public WIHS website is a useful source of information about WIHS including how the consortium collaborates with non-WIHS investigators. Some NIH-funded collaborators include: North America region of the International Epidemiologic Databases to Evaluate AIDS, the Centers for AIDS Research, Multicenter AIDS Cohort Study.
- The WIHS-V FOA suggests areas of focus in the “Research Scope of WIHS-V” section, but are applications limited to only those areas?
The areas of focus suggested in the “Research Scope of WIHS-V” section were not intended to be all inclusive. In addition, proposed projects are expected to be well integrated across several areas and disciplines whether or not the proposed scientific topics were suggested in the FOA.
- How can substance use aims, sub-aims, or hypotheses reflect the integrated objectives and research scope examples in the FOA?
Substance use-related research in the WIHS should take advantage of the unique opportunities of a long-term clinical cohort, and should be consistent with the major priority research domains (treatment, co-morbidities and pathogenesis) as presented in the FOA. The effects of substance use on factors such as specific risk behaviors (e.g., sexual practices), health behaviors, or psychological status associated with aging, should occur in the context of clinical outcomes that reflect the larger priority objectives of WIHS. Similarly, substance use and patterns of substance use over time, and their relationship to natural and treated disease history should be considered with respect to the broader clinical research agenda, including co-morbidities (e.g., metabolic consequences, liver function, cardiovascular disease, HCV, neurocognitive functioning), therapeutics (e.g., adherence, treatment impact, resistance), and pathogenesis (e.g., immune function, host genetics). Proposed projects should highlight opportunities for both focused and integrated investigations not possible in typical community or clinic samples.
