What is the NIH R37 grant?

The R37 (MERIT Award) is awarded by the institute, not by direct application. It extends a top-scoring R01 to up to 7 years (instead of 5) without requiring a competing renewal in year 5. ICs vary in how aggressively they convert R01s to R37s.

  • Dissecting the Role Ubiquitin E3 Ligase UBR5 in Lymphomagenesis

    4R37CA262635-06
    Shannon Buckley · UTAH STATE HIGHER EDUCATION SYSTEM--UNIVERSITY OF UTAH, UT · $410,861 · awarded Aug 26, 2026 · NIH

    ABSTRACT Mantle cell lymphoma (MCL) is a rare and aggressive non-Hodgkin’s lymphoma. Unfortunately limited therapies for MCL are currently available suggesting a need to further unravel molecular mechanisms regulating transformation and progression of the disease. The majority of MCL patients have mutations leading to overexpression of CyclinD1 leading to…

  • Statistical Methods for Efficacy Trials of Vaccines and Monoclonal Antibodies Against Genetically-Diverse Pathogens

    5R37AI054165-25
    Peter Gilbert · FRED HUTCHINSON CANCER CENTER, WA · $497,934 · awarded Aug 26, 2026 · NIH

    PROJECT SUMMARY (See instructions): Safe and efficacious vaccines are needed to massively reduce the economic and human health costs of HIV-1/AIDS, dengue, malaria, and COVID-19. This goal has been hindered by the genetic diversity of the etiological pathogens. Randomized, controlled trials that rigorously assess the efficacy of candidate vaccines to…

  • Aire-expressing macrophages as novel mediators of tumor immune evasion

    5R37CA304094-02
    James Gardner · UNIVERSITY OF CALIFORNIA, SAN FRANCISCO, CA · $677,249 · awarded Aug 25, 2026 · NIH

    Project Summary/Abstract Immunotherapy has revolutionized the treatment of cancer, but many malignancies remain resistant to these interventions. Defining novel mechanisms by which tumors evade immune responses is therefore of critical importance. While extensive work has focused on effector and regulatory T-cell populations in tumors and their roles in the…

  • A novel, one stop, affordable, point of care and artificial intelligence supported system of screening, triage and treatment selection for cervical cancer and precancer in the LMICs

    5R37CA275824-04
    Partha Basu · INTERNATIONAL AGENCY FOR RES ON CANCER · $147,753 · awarded Aug 24, 2026 · NIH

    EASTER Application identifier 1161104 Summary statement Artificial intelligence (AI) has penetrated many medical disciplines, AI is fast gaining reputation as offering highly promising solutions for cervical cancer prevention, in particular the AI-supported image capture and prediction of cervical abnormality or Automated Visual Examination (AVE). Despite…

  • Symptom Management and Transitioning to Engagement with Post-treatment Care for Adolescent and Young Adult Cancer Survivors (AYA STEPS)

    5R37CA283353-03
    Caroline Dorfman · DUKE UNIVERSITY, NC · $664,941 · awarded Aug 20, 2026 · NIH

    There are more than 600,000 adolescent and young adult (AYA; age 15-39 at diagnosis) cancer survivors in the U.S. The number of AYA survivors continues to grow due to both an increased cancer incidence and treatment advances (i.e., five-year survival rates > 80%). For AYA survivors, the impacts of treatment are significant and long-lasting, including…

  • Next-Generation Tomosynthesis Pilot Study

    4R37CA273959-05
    Raymond Acciavatti · UNIVERSITY OF PENNSYLVANIA, PA · $367,143 · awarded Aug 17, 2026 · NIH

    PROJECT SUMMARY Even with the latest digital breast tomosynthesis (DBT) systems, breast cancer screening continues to suffer from poor specificity. Only about 5% of women called-back from screening are ultimately found to have a biopsy- proven cancer. Clinical DBT systems suffer from anisotropies in image quality since the scanning motion is restricted to…

  • Generation and Description of Neuronal Morphology and Connectivity

    2R37NS039600-25
    GIORGIO ASCOLI · GEORGE MASON UNIVERSITY, VA · $397,750 · awarded Aug 14, 2026 · NIH

    Dendritic and axonal morphologies play fundamental roles in physiological brain function and pathological dysfunction by affecting synaptic integration, spiking dynamics, and circuit connectivity. Incorporating published experimental data into accurate, full-scale, biologically plausible neural network simulations is important for quantitatively linking the…

  • Targeting the Super Elongation Complex to Regulate HIV Transcription and Latency

    1R37AI194870-01A1
    Judd Hultquist · NORTHWESTERN UNIVERSITY, IL · $804,464 · awarded Aug 14, 2026 · NIH

    PROJECT SUMMARY The persistence of Human Immunodeficiency Virus (HIV) in long-lived latent reservoirs remains one of the major barriers to a functional cure. The latent reservoir consists of cells harboring replication-competent, but transcriptionally inhibited proviruses that evade immune clearance even in patients on long-term antiretroviral therapy…

  • UNCOVER-PC: Uniting Novel Concepts of Value to Enhance Reform in Palliative Care

    1R37CA307515-01A1
    Xin Hu · EMORY UNIVERSITY, GA · $682,730 · awarded Aug 12, 2026 · NIH

    Abstract More than 600,000 people with cancer die in the US annually. Many experience avoidable suffering and poor quality of life (QoL) due to inadequate symptom management. Early outpatient specialty palliative care (PC) has demonstrated benefits on QoL and end-of-life (EOL) outcomes in clinical trials as early as 2010, leading national guidelines to…

  • Chemokines and Lymphoid Tissue Organization and Function

    5R37AI045073-28
    Jason Cyster · UNIVERSITY OF CALIFORNIA, SAN FRANCISCO, CA · $562,480 · awarded Aug 10, 2026 · NIH

    Project Summary/Abstract The intestinal immune system plays crucial roles in maintaining tissue and microbiome homeostasis and in protecting from pathogens. Two major classes of intestinal immune cells are the intraepithelial lymphocytes (IEL) and IgA producing cells. The factors controlling the compartmentalization and homeostasis of immune cells in…

  • Initiation of the Immune Response to Aspergillus Fumigatus

    4R37AI093808-17
    TOBIAS HOHL · SLOAN-KETTERING INST CAN RESEARCH, NY · $806,922 · awarded Aug 10, 2026 · NIH

    The immune system clears inhaled Aspergillus fumigatus (Af) conidia, blocks the formation of invasive hyphae, and prevents dissemination, primarily to the central nervous system (CNS). Invasive aspergillosis (IA) is a feared disease in immunocompromised patients and despite contemporary antifungal drugs, IA-attributable mortality rates remain 20-40% in…

  • Disrupting MDSC-fibroblast interactions to overcome chemoimmunotherapy resistance in pancreatic cancer

    5R37CA292843-03
    Jashodeep Datta · UNIVERSITY OF MIAMI SCHOOL OF MEDICINE, FL · $351,131 · awarded Aug 7, 2026 · NIH

    PROJECT SUMMARY Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy projected to be the 2nd leading cause of cancer-related deaths in the United States by 2030, with a dismal 5-year survival of 12%. PDAC is refractory to standard chemotherapy and immunotherapy due to intrinsic and acquired resistance. Two key culprits associated with therapeutic…

See above.

Who applies for R37

You do not apply directly. You apply for an R01; if your application scores in the top range, the institute may convert it to an R37.
