NOT-CA-21-114 - Notice of Intent to Publish a Funding Opportunity Announcement for Clinical Sites for the HIV/Cervical Cancer Prevention 'CASCADE' Clinical Trials Network (UG1 Clinical Trial Required)

Issued by

National Cancer Institute (NCI)


The purpose of this Notice is to announce the NCI's intention to issue a Funding Opportunity Announcement (FOA) that invites applications for UG1(Cooperative Agreement)-funded Research Bases for the HIV/Cervical Cancer Prevention ‘CASCADE’ Clinical Trials Network. The ‘CASCADE’ Network seeks to conduct pragmatic clinical trials evaluating the effectiveness of clinically proven interventions to overcome barriers and reduce failures in the cervical cancer screening, management, and precancer treatment cascade for women living with HIV.

The ‘CASCADE’ Network will be structured around three types of organizational units (funded by individual Cooperative Agreement grants): a single U24-funded Coordinating Center, up to three UG1-funded Research Bases, and up to eight UG1-funded Clinical Sites, all working collaboratively and in partnership with the NCI. The UG1 Research Bases will provide scientific and statistical leadership for developing and analyzing multi-institutional clinical trial concepts and protocols for implementation at multiple UG1 Clinical Sites, partner with the U24 Coordinating Center and the UG1 Clinical Sites to ensure compliance with human research participant protection and other regulatory and administrative reporting requirements, as well as work towards creating opportunities for training emerging investigators.

This Notice is being provided to allow potential applicants sufficient time to develop responsive applications for UG1 (Cooperative Agreement)-funded Research Bases for the ‘CASCADE’ Network. The FOA is expected to be published in Fall 2021 with an anticipated application due date in late Winter 2021. Details of a planned pre-application webinar will be announced after the publication of the FOA.

This FOA will utilize the UG1 activity code. Details of the planned FOA are provided below.

Research Initiative Details

Women living with HIV (WLWH) have a higher risk for acquisition, persistence, and progression of cervical human papillomavirus (HPV) to precancerous lesions, which, in the absence of effective screening and treatment services, can progress to invasive cancer at five-to-six times higher rates than in women without HIV. The massive global mobilization of humanitarian resources spanning over the past couple of decades, through initiatives such as the US President’s Emergency Plan for AIDS Relief (PEPFAR), has resulted in millions of WLWH in low- and middle-income countries (LMICs) now accessing affordable antiretroviral therapy and consequently living longer lives. Yet, their risk for cervical cancer continues unabated since effective screening and precancer treatment services remain unavailable in most LMICs. The lack of such services has prompted efforts funded by PEPFAR and several public, private, and philanthropic-sector agencies to increase access to cervical cancer prevention services, especially within/linked to the clinics and facilities where WLWH routinely access HIV/AIDS care and treatment services. In addition, the World Health Organization (WHO), with endorsement of 194 countries including the United States, has launched a global initiative to accelerate progress towards the elimination of cervical cancer as a public health problem. Concurrently, there have been significant advances in key catalytic technologies (such as point-of-care visual and molecular screening approaches, and multiple portable ablative and excisional precancer treatment devices) and acceleration of regulatory pathways (such as imminent approvals for self-sampling for HPV-based primary screening) for key clinical interventions for cervical cancer screening and precancer treatment.

The ‘CASCADE’ Network will build on the momentum stimulated by these developments and seek to conduct pragmatic clinical trials evaluating the effectiveness of clinically proven interventions in intended-use settings to optimize the cervical cancer screening, management, and precancer treatment cascade for WLWH. ‘CASCADE’ Network trials will be conducted in intended-use environments in resource-constrained settings in low and middle-income countries and in regions with health disparities in the United States, and will have four major scientific focus areas:

  • increasing screening uptake,
  • improving management of screen positives,
  • facilitating precancer treatment access, and
  • optimizing precancer treatment for cervical cancer prevention in WLWH.

These studies will take advantage of, and build on, the infrastructures of existing service delivery initiatives and utilize 'hybrid effectiveness-implementation' study designs to simultaneously evaluate the effectiveness of clinical interventions in intended-use settings (via measurement of outcomes such as precancer detection rates, rates of recurrence, etc.) while gathering crucial information (e.g., costs, acceptability, intervention fidelity) informing the implementation and scale-up of such interventions.

The ‘CASCADE’ network is expected to develop and conduct a total of six to eight multicenter clinical trials over a five-year project period. Clinical trial concepts and protocols will be proposed and developed by UG1 Research Bases, and participant accrual will occur at multiple UG1 Clinical Sites, matching the scientific focus with the availability of infrastructure and access to appropriate study populations. The U24 Coordinating Center will facilitate network-wide coordination, scientific review, data management, and independent risk-appropriate auditing of network clinical trials. A Network Steering Committee, with representation from principal investigators from the ‘CASCADE’ Network grantees and NCI staff will review and prioritize clinical trial concepts and selection of study implementation sites after balancing competing considerations around scientific focus, geographic distribution of studies across the network, trial accrual targets, protocol implementation complexity, and strategic partnership opportunities. Final approval for protocols will be provided via an NCI Oversight Committee.

‘CASCADE’ Network trials are expected to inform clinical practice guidelines and improve implementation of cervical cancer prevention and control programs globally. Through this notice, NCI wants to provide early visibility of this initiative to encourage development of partnerships to prepare responsive applications in response to the UG1 (Cooperative Agreement) Research Bases FOA. UG1 Research Bases are expected to provide scientific and statistical leadership for developing, overseeing, and analyzing multi-institutional pragmatic clinical trial protocols in at least two of the four scientific focus areas of the ‘CASCADE’ Network that will be implemented at the UG1 Clinical Sites. It is expected that the UG1 Research Base applicants will be self-organized multi-disciplinary teams co-led by US-based and/or LMIC-based PIs with complementary expertise in areas such as clinical effectiveness research, HPV/cervical cancer prevention and control, HIV/AIDS care, and gynecology/women’s health/reproductive health issues.
