ZUG, Switzerland, CAMBRIDGE, Mass., and SOUTH SAN FRANCISCO, Calif., May 06, 2021 (GLOBE NEWSWIRE) -- CRISPR Therapeutics (NASDAQ: CRSP), a biopharmaceutical company focused on developing transformative gene-based medicines for serious diseases, and Nkarta, Inc. (NASDAQ: NKTX), a biopharmaceutical company developing engineered NK cell therapies to treat cancer, today announced a strategic partnership to research, develop, and commercialize CRISPR/Cas9 gene-edited cell therapies for cancer.

Under the agreement, the companies will co-develop and co-commercialize two CAR NK cell product candidates, one targeting the CD70 tumor antigen and the other target to be determined. In addition, the companies will bring together their complementary cell therapy engineering and manufacturing capabilities to advance the development of a novel NK+T product candidate harnessing the synergies of the adaptive and innate immune systems. Finally, Nkarta obtains a license to CRISPR gene editing technology to edit five gene targets in an unlimited number of its own NK cell therapy products.

CRISPR Therapeutics and Nkarta will equally share all research and development costs and profits worldwide related to the collaboration products. For each non-collaboration product candidate incorporating a gene editing target licensed from CRISPR Therapeutics, Nkarta will retain worldwide rights and pay CRISPR Therapeutics milestones and royalties on net sales. The agreement includes a three-year exclusivity period between CRISPR Therapeutics and Nkarta covering the research, development, and commercialization of allogeneic, gene-edited, donor-derived NK cells and NK+T cells.

By bringing together CRISPR Therapeutics and Nkartas highly complementary expertise and proprietary platforms we plan to accelerate the development of potentially groundbreaking genome engineered NK cell therapies, said Samarth Kulkarni, Ph.D., Chief Executive Officer at CRISPR Therapeutics. This collaboration broadens the scope of our efforts in oncology cell therapy, and expands our efforts to discover and develop novel cancer therapies for patients.

Uniting the best-in-class gene editing solution and allogeneic T cell therapy expertise of CRISPR with Nkartas best-in-class CAR NK cell therapy platform will be a major advantage to advancing the next wave of transformative cancer cell therapies, said Paul J. Hastings, President and Chief Executive Officer of Nkarta. With this partnership, Nkarta can systematically apply world-class gene editing across our entire pre-clinical pipeline going forward. CRISPRs deep understanding of CD70 biology and experience in allogeneic T cell clinical development can accelerate the development of early-stage Nkarta programs, to deliver innovative treatments to patients that much faster.

Nkarta Conference Call DetailsNkarta management will host a conference call to discuss the collaboration today at 4:30 p.m. Eastern Time (ET). The event will be simultaneously webcast and available for replay from the Nkarta website at http://www.nkartatx.com, under the Investors section. Investors may also participate in the conference call by calling 877-876-9174 (domestic) or +1-785-424-1669 (international). The conference ID is NKARTA.

CRISPR Therapeutics Forward-Looking StatementThis press release may contain a number of forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended, including statements made by Dr. Kulkarni and Mr. Hastings in this press release, as well as statements regarding CRISPR Therapeutics expectations about any or all of the following: (i) the future activities of the parties pursuant to the collaboration and the expected benefits of CRISPR Therapeutics collaboration with Nkarta; and (ii) the therapeutic value, development, and commercial potential of CRISPR/Cas9 gene editing technologies and therapies. Without limiting the foregoing, the words believes, anticipates, plans, expects and similar expressions are intended to identify forward-looking statements. You are cautioned that forward-looking statements are inherently uncertain. Although CRISPR Therapeutics believes that such statements are based on reasonable assumptions within the bounds of its knowledge of its business and operations, forward-looking statements are neither promises nor guarantees and they are necessarily subject to a high degree of uncertainty and risk. Actual performance and results may differ materially from those projected or suggested in the forward-looking statements due to various risks and uncertainties. These risks and uncertainties include, among others: CRISPR Therapeutics may not realize the potential benefits of the collaboration, uncertainties inherent in the initiation and completion of preclinical studies; availability and timing of results from preclinical studies; whether results from a preclinical study will be favorable and predictive of future results of future studies or clinical trials; uncertainties about regulatory approvals and that future competitive or other market factors may adversely affect the commercial potential for product candidates; potential impacts due to the coronavirus pandemic, such as the timing and progress of preclinical studies; uncertainties regarding the intellectual property protection for CRISPR Therapeutics technology and intellectual property belonging to third parties, and the outcome of proceedings (such as an interference, an opposition or a similar proceeding) involving all or any portion of such intellectual property; and those risks and uncertainties described under the heading "Risk Factors" in CRISPR Therapeutics most recent annual report on Form 10-K, quarterly report on Form 10-Q, and in any other subsequent filings made by CRISPR Therapeutics with the U.S. Securities and Exchange Commission, which are available on the SEC's website at http://www.sec.gov.

About Nkartas NK Cell TechnologiesNkarta has pioneered a novel discovery and development platform for the engineering and efficient production of allogeneic, off-the-shelf natural killer (NK) cell therapy candidates. The approach harnesses the innate ability of NK cells to recognize and kill tumor cells. To enhance the inherent biological activity of NK cells, Nkarta genetically engineers the cells with a targeting receptor designed to recognize and bind to specific proteins on the surface of cancerous cells. This receptor is fused to co-stimulatory and signaling domains to amplify cell signaling and NK cell cytotoxicity. Upon binding the target, NK cells become activated and release cytokines that enhance the immune response and cytotoxic granules that lead to killing of the target cell. All of Nkartas NK current cell therapy candidates are also engineered with a membrane-bound IL15, a proprietary version of a cytokine known for activating NK cell growth, to enhance the persistence and activity of the NK cells.

Nkartas manufacturing process generates an abundant supply of NK cells that, at commercial scale, is expected to be significantly lower in cost than other current allogeneic and autologous cell therapies. Key to this efficiency is the rapid expansion of donor-derived NK cells using a proprietary NKSTIM cell line, leading to the production of hundreds of individual doses from a single manufacturing run. The platform also features the ability to freeze and store CAR NK cells for an extended period of time and is designed to enable immediate, off-the-shelf administration to patients at the point of care.

About NkartaNkarta is a clinical-stage biotechnology company advancing the development of allogeneic, off the shelf natural killer (NK) cell therapies for cancer. By combining its cell expansion and cryopreservation platform with proprietary cell engineering technologies, Nkarta is building a pipeline of cell therapy candidates generated by efficient manufacturing processes, which are engineered to enhance tumor targeting and improve persistence for sustained activity in the body.
