  • The NIH said it plans to award approximately $190 million over six years to researchers, starting this year, toward developing tools and technologies designed to enable safe and effective genome editing in humans.

    “Genome editing technologies such as CRISPR/Cas9 are revolutionizing biomedical research. The focus of the Somatic Cell Genome Editing program is to dramatically accelerate the translation of these technologies to the clinic for treatment of as many genetic diseases as possible,” NIH Director Francis S. Collins, M.D., Ph.D., said yesterday in a statement.

    Through the new program, researchers would receive funding for tools and tech that accelerate adoption of genome editing for treating patients. Among categories of projects the NIH said it planned to fund are those that:

    • Improve the delivery mechanisms for targeting gene editing tools in patients,
    • Develop new and improved genome editors,
    • Develop assays for testing the safety and efficacy of the genome editing tools in animal and human cells, and

    Researchers funded through the Somatic Cell Genome Editing  program are expected by the NIH to assemble the tools and tech they develop into a genome editing “toolkit” of knowledge, methods, and tools, all to be shared with the scientific community.

    The NIH said funding opportunity announcements for the program are expected to be issued within a month. The program will be funded through NIH’s Common Fund, and managed by a trans-agency Working Group representing multiple NIH Institutes and Centers, led by the National Center for Advancing Translational Sciences (NCATS).

    Because the program is focused on non-reproductive somatic cells, any changes to the DNA wrought by the genome editing tools and tech will not be inherited—avoiding the ethical qualms raised by permanent germline editing of human genomes.

    Somatic cell genome editing is among applications of CRISPR (clustered regularly interspaced short palindromic repeats) technology to be explored by The CRISPR Journal, an international, multidisciplinary peer-reviewed journal being launched this year by GEN publisher Mary Ann Liebert Inc.

    “NIH enabling the CRISPR-Cas9 path to the clinic is timely and obviously aligned with the institute's mission,” Rodolphe Barrangou, Ph.D., M.B.A., editor-in-chief of The CRISPR Journal and associate professor of Food Science, North Carolina State University, told GEN today. “With the current momentum of the technology and all efforts underway to advance the technology, its delivery, specificity and efficacy, this is a timely and noteworthy investment taking CRISPR to the next phase of the journey to the clinic on a broader scale.”

    The program, Dr. Barrangou said, reflected growing commitments by federal agencies to CRISPR in addition to increasing private and industry investments in the genome editing technology.

    Added Samuel H. Sternberg, Ph.D., an assistant professor at Columbia University and an associate editor of The CRISPR Journal: “I'm thrilled to hear of the funding announcement from the NIH. Gene editing-based therapies show incredible potential to treat disease, and strong financial support from the NIH will stimulate research and accelerate the pace at which these therapies can be made available to patients.”

  • Filling Translation Gaps

    The program emerged following a July 2017 workshop that brought together researchers and executives from industry, academia, and federal agencies, along with patient advocates. They discussed the potential for NIH action and identified five gaps toward translation of gene editing technologies into therapies: Relevant human and animal model systems for preclinical testing; cell- and tissue-specific delivery systems; standardized assays for measuring genetic off-target effects; improved editing machinery (nuclease alternatives); and long-term cell tracking assays.

    The program was first publicly discussed September 1, 2017, during a presentation to the NIH’s Council of Councils by Mary Ellen Perry, Ph.D., a program leader in the agency’s Office of Strategic Coordination.

    “We’re hoping that we’ve come up with a concept that would help to accelerate the approaches for therapeutic genome editing. There are multiple challenges and opportunities in this area,” Dr. Perry said. “There are thousands of incurable genetic diseases which now at least potentially or theoretically are treatable through these new gene editing technologies.”

    In slides accompanying her presentation, Dr. Perry said the program’s goal was to facilitate Phase I/II trials of new somatic gene editing therapies by developing and providing broad access to: Animal models for gene editing research and preclinical testing; New methods to assess intended and unintended biological effects; Efficient, effective, and specifically-targeted in vivo delivery systems; and improved human gene editing tools.

    Dr. Perry said the program’s potential impact included increased access to IND-enabling technologies, accelerated filings of INDs and faster approvals for new gene editing therapies, new therapeutic approaches, and even cures for monogenic diseases.

    The announcement of the program was reported without comment by China’s state-run Xinhua news agency. At least 86 Chinese patients have had their genes edited in clinical trials of CRISPR/Cas9 technologies, The Wall Street Journal reported on January 21.

    China has raced ahead in pursuing gene editing trials in human patients, launching the first such trial in 2016, while a planned CRISPR trial by University of Pennsylvania researchers has yet to start. The Penn trial is to be led by Carl June, M.D., who told Nature in 2016: “I think this is going to trigger ‘Sputnik 2.0’, a biomedical duel on progress between China and the United States, which is important since competition usually improves the end product.”
