Opportunity Summary:

The Adult to Adult Living Donor Liver Transplantation Cohort Study (A2ALL) (U01) funding opportunity (RFA DK 09 003) is a National Institutes of Health cooperative agreement announcement issued by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) to support the continuation of a major clinical research network focused on adult-to-adult living donor liver transplantation (LDLT). The core aim is to generate strong, real-world evidence on both the near-term and long-term outcomes of LDLT for two groups that matter most in this procedure: the living donors who undergo surgery without direct medical benefit to themselves, and the transplant recipients whose survival and quality of life depend on the transplant. Beyond clinical outcomes, the study is also positioned to deepen scientific understanding of liver regeneration and other biological processes that can be uniquely examined in the setting of partial liver donation and regrowth.

The program is designed as a coordinated network rather than a single-center project. NIH plans to fund up to nine clinical transplant centers (TCs) plus one centralized data coordinating center (DCC). The transplant centers would be responsible for enrolling and following donors and recipients, collecting standardized clinical data, and implementing common research protocols. The data coordinating center would serve as the hub for data management and quality control, statistical analysis, and cross-site coordination so that findings are comparable across institutions and can be combined into a single, rigorous cohort. This structure is meant to support large-scale, multi-site cohort research where consistent methods, shared governance, and centralized analytics are essential for credible results.

The award uses the NIH Cooperative Agreement (U01) mechanism, which signals that the NIH will have substantial programmatic involvement compared with a traditional investigator-initiated grant. In practical terms, applicants should expect an active partnership with NIDDK staff in areas such as study governance, protocol development or refinement, performance monitoring, and network-wide decision-making. The goal of that cooperative structure is to keep the network aligned around shared milestones, common data standards, and a cohesive scientific agenda that can reliably answer complex questions about LDLT outcomes and biology.

From a funding standpoint, NIDDK anticipated a total program budget of about $3.5 million through this announcement, with an expected set of awards covering the clinical sites and the single DCC. The listed award ceiling is $250,000 (as provided in the source data). The opportunity does not require cost sharing or matching, which lowers barriers for participation and helps ensure that scientific and clinical capability, rather than institutional ability to contribute matching funds, drives competitiveness.

Eligibility is broad and intentionally inclusive. Applications were welcomed from a wide range of organization types, including public and private institutions of higher education, nonprofit organizations (including both 501(c)(3) and non-501(c)(3)), for-profit organizations (including small businesses), state and local governments, tribal governments and tribal organizations, public housing authorities, independent school districts, and various special district and regional entities. The eligibility language also explicitly includes institutions such as Historically Black Colleges and Universities (HBCUs), Hispanic-serving institutions, Tribally Controlled Colleges and Universities (TCCUs), Alaska Native and Native Hawaiian-serving institutions, and faith-based or community-based organizations. Foreign institutions were permitted only if located within North America. Importantly, the announcement emphasizes that participation is not limited to the centers already involved in A2ALL, meaning new transplant programs and coordinating groups could compete to join or lead components of the next phase.

Key dates included a posting and creation date of December 12, 2008, with an original and current closing date of March 19, 2009, and an archive date of April 19, 2009. The opportunity is categorized as discretionary funding, with the activity category listed under health (and tagged in the source record with food and nutrition/health categorization) and is associated with CFDA 93.847 (Diabetes, Digestive, and Kidney Diseases Extramural Research).

In summary, this FOA sought to sustain and expand a national, multi-center LDLT cohort infrastructure capable of answering high-impact questions about donor safety, recipient outcomes, and liver regeneration through a tightly coordinated NIH-supported network. The deliverable implied by the structure is not just individual site studies, but a unified, high-quality cohort dataset and collaborative research output that can guide clinical practice, inform patient counseling and risk assessment, and advance the biological science that is uniquely accessible through living donor liver transplantation.

Frequently Asked Questions (FAQs)

What is the A2ALL (U01) funding opportunity?

The Adult to Adult Living Donor Liver Transplantation Cohort Study (A2ALL) (U01) funding opportunity (RFA DK 09 003) is a National Institutes of Health (NIH) cooperative agreement announcement issued by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
