Gene drive systems

Peking University, the University of California and the University of California at San Diego are among the leading research organizations in the recent window, with 33, 45 and 43 documents respectively. Imperial College London is also active, with work on malaria-vector modification and resistance. These organizations span research on inheritance performance, mosquito control and strategies to make drive systems more resilient.

FACTS records $8,720,880 in grants across 20 awards since 2020. The funding data is grant-level and does not identify a complete set of funding sources or public programs for the field. The available funding-round entries also include unrelated activity, so they should not be treated as gene-drive-specific investment totals.

Six organizations are tied at 1 patent each in the listed patent-holder data: North Carolina State University, Imperial College London, California Institute of Technology, Buck Institute for Age Research, Wisconsin Alumni Research Foundation and Fred Hutchinon Cancer Center. The available figures therefore do not identify a single leading holder. They also do not show the scope or status of each patent.

No: FACTS records 6 patents in the 24-month window and reports patent growth of -100.0% for the last 12 months versus the previous 12 months. That decline contrasts with 216 publications in the last year and publication growth of 17.4%. The figures describe activity in the dataset, not the overall commercial potential or quality of patent filings.

Gene drive systems remain research-led: FACTS records 0 clinical trials, alongside 1,702 publications and 63 patents overall. Recent studies address laboratory performance, resistance, confinement and ecological risk rather than established clinical or commercial deployment. This profile reflects an experimental technology intended to alter populations, where evidence about inheritance and potential spread is central to assessing readiness.

Recent studies include Imperial College London’s work on overcoming target-site resistance in Anopheles gambiae in September 2026, and research on multiplexed confineable drives in Anopheles stephensi in August 2026. Imperial College London also reported an integral nanosd drive for population modification in August 2026. Together, these efforts target resistance, drive design and malaria-vector control.

The approaches include homing drives, split drives, daisy-chain drives, toxin–antidote systems, underdominance systems and meiotic sex-ratio drives. Homing drives bias inheritance through copying; split and daisy-chain designs separate components to manage persistence; underdominance depends on an introduction threshold. Toxin–antidote systems favor inheritance through linked effects, while sex-ratio drives bias offspring sex. Each design trades spread efficiency against control or persistence.

The United States leads with 1,757 documents (58.7%), followed by the United Kingdom with 792 (26.5%) and China with 347 (11.6%). Germany, Switzerland and Australia are also represented in the country data. These figures indicate where documents are attributed, rather than comparing research quality, funding levels or the number of active development programs.

Vector-borne disease control is the largest listed application, with 108 documents; invasive species suppression has 62. Agricultural pest and weed management has 31 documents, while conservation and ecosystem management has 29. Recent work on malaria mosquitoes illustrates the disease-control focus, while other research considers suppression and ecological management. Each use raises distinct questions about target populations, spread and environmental effects.
