Gene therapy — NIH Funding Overview

Reviewed by Dr. Meng ZhaoLast reviewed June 9, 2026Data refreshed June 9, 2026Editorial standards

Gene therapy is a fast-growing NIH funding category covering AAV-based delivery, lentiviral and ex vivo approaches, CRISPR-based corrections, and emerging RNA-based therapies. Multiple ICs fund disease-specific applications, with NHGRI and NHLBI leading platform development.

Why this matters now

Multiple FDA approvals (Zolgensma, Hemgenix, Casgevy, Elevidys, others) have validated the field, but each new therapy reveals long-tail safety, manufacturing, and access challenges that drive NIH portfolio reorganization toward delivery, immunogenicity, and durability research.

How NIH funds this area

Mechanisms include R01, U01, U19, P01, and the Bridge to Artificial Intelligence (Bridge2AI) and Somatic Cell Genome Editing programs. Data below covers all NIH awards mentioning gene therapy in title, abstract, or terms.

How to use this funding brief

Use this page to decide whether vector design, delivery, editing, manufacturing, safety, or a disease application is the real funding question. Search the platform and disease terms independently before using recent award counts as evidence of field momentum.

Search tactics

  • Search "AAV" or "lentiviral" for vector-specific subsets.
  • For ex vivo cell therapies, search "CAR-T" or "cell therapy".
  • NHGRI and NHLBI lead platform-level grants; disease-specific work flows to disease ICs.

What the data shows

$209M$417M$626M$834MFY21FY22FY23FY24FY25FY26*
Total NIH award dollars mentioning Gene therapy per fiscal year, from the NIH RePORTER snapshot refreshed June 9, 2026. *The most recent fiscal year is still accumulating awards.
  • Funding peaked in FY2025 at $834M. The FY2025 total of $834M is +45% versus FY2021.
  • The number of awards rose about 4% in FY2025.
  • About 83% of FY2026 dollars so far are renewals and continuations. Mid-year snapshots overweight renewals because non-competing continuations are issued early in the fiscal year, but the share still indicates how much of the portfolio is committed before new applications compete.
  • The average FY2025 award was $697K, and R01 was the most common mechanism in the recent window.

Editorial read

Gene-therapy funding grew roughly 45% from FY2021 to a record FY2025 — among the fastest growth in our tracked set — and the money is following delivery vehicles, manufacturing, and clinical translation rather than proof-of-concept constructs. The portfolio also shows one of the lower renewal shares in the current-year snapshot, a sign that new projects are still being added at a healthy clip rather than the base simply rolling over.

Counts and total funding per fiscal year from NIH RePORTER. Recent fiscal years may understate final totals because of reporting lag.

  • Defining Barriers to Gene Therapy

    5R01EY018213-18
    Stephen Tsang · COLUMBIA UNIVERSITY HEALTH SCIENCES, NY · $405,751 · awarded Jun 5, 2026 · R01

    PROJECT SUMMARY Of the retinal degenerative diseases that affect 9 million Americans, rod and cone photoreceptor dystrophies are arguably the most devastating. Gene therapy is a potential means to strengthen photoreceptor viability. However, the first human gene therapy trial for retinal degeneration found improved visual function but did not slow…

    1R21NS148969-01
    Marc Forrest · NORTHWESTERN UNIVERSITY, IL · $240,000 · awarded Jun 5, 2026 · R21

    ABSTRACT Alternative splicing vastly expands the functional repertoire of genes, and is especially important during human synapse development. Human synapses have unique structures and compositions, but the mechanisms involved in their development remains elusive. Investigations into human-specific aspects of synaptic machinery have revealed a critical role…

    1R01HD120555-01
    David Pepin · MASSACHUSETTS GENERAL HOSPITAL, MA · $730,972 · awarded Jun 3, 2026 · R01

    Project Summary/Abstract: Current hormonal contraceptives work by disrupting the hypothalamic-pituitary-gonadal axis and preventing follicle development only in its last stage leading to ovulation. All current hormonal contraceptives share unwanted side effects due to the wide tissue distribution of sex steroid receptors. In contrast, anti-Müllerian hormone…

  • Neuron-specific modulation of gene expression using systemically administered bispecific antibody-ASO conjugates

    5R01NS138455-03
    Greg Thurber · UNIVERSITY OF MICHIGAN AT ANN ARBOR, MI · $599,383 · awarded Jun 3, 2026 · R01

    The ability to selectively modulate the expression of one or more neuronal genes is critical for defining pathways that govern normal brain physiology and diverse disease phenotypes. Anti-sense oligonucleotides (ASOs) are attractive agents for manipulating neuronal gene expression, especially given their clear advantages relative to gene therapy, including…

  • eCD4-Mediated Control of SIV Infection in the Brain

    5R01NS131098-04
    Michael Farzan · BOSTON CHILDREN'S HOSPITAL, MA · $848,912 · awarded Jun 3, 2026 · R01

    PROJECT SUMMARY Combined antiretroviral therapy (ART) has revolutionized the treatment of HIV but ART regimens are not without drawbacks. Cost, the need for daily administration, side effects, and social stigma all contribute to reduced patient compliance. Moreover, despite treatment, some 15-55% of people living with HIV will develop some form of…
