CAMBRIDGE, MA and NEW YORK, NY, USA I February 16, 2021 I Cytovia Therapeutics, Inc., a biopharmaceutical company developing allogeneic “off-the-shelf” gene-edited Natural Killer (NK) and Chimeric Antigen Receptor (CAR)-NK cells derived from induced pluripotent stem cells (iPSCs), and Cellectis (Euronext Growth: ALCLS – Nasdaq: CLLS) a clinical-stage biopharmaceutical company focused on developing immunotherapies based on gene-edited allogeneic CAR T-cells (UCART), announced today that they have entered into a strategic research and development collaboration to develop TALEN® gene-edited iPSC NK and CAR-NK cells. 

The financial terms of the partnership include up to $760 million of development, regulatory, and sales milestones from Cytovia to Cellectis for the first 5 TALEN® gene-edited iPSC-derived NK products (“partnership products”). Cellectis will also receive single-digit royalty payments on the net sales of all partnered products commercialized by Cytovia. Cellectis will receive an equity stake of $15 million in Cytovia stock or an upfront cash payment of $15 million if certain conditions are not met by December 31, 2021, as well as an option to invest in future financing rounds.

“We are excited to collaborate with Cellectis, a gene-editing pioneer and leader in the development of gene-edited allogeneic cancer therapies, to further accelerate Cytovia’s NK cell programs,” said Dr. Daniel Teper, Chairman & CEO of Cytovia Therapeutics. “Cellectis has a deep understanding and proven expertise in gene-edited cell therapies, and their gene editing technology, TALEN®, will yield NK and CAR-NK treatments with improved potency, persistence, and safety for a variety of cancers, including solid tumors. We look forward to leveraging Cellectis’ insights and experience to help move Cytovia’s CAR-NKs into clinical trials by 2022.”

Cellectis will develop custom TALEN®, which Cytovia will use to edit iPSCs. Cytovia will be responsible for the differentiation and expansion of the gene-edited iPSC master cell bank into NK cells and will conduct the pre-clinical evaluation, clinical development, and commercialization of the mutually-agreed-upon selected therapeutic candidates. Cellectis is granting Cytovia a worldwide license to its TALEN® gene-editing technology, enabling Cytovia to modify NK cells addressing multiple gene targets for therapeutic use in several cancer indications.

“We are thrilled to partner with Cytovia, a pioneer in the development of NK cells derived from iPSCs,” said Dr. André Choulika, CEO of Cellectis. We are looking forward to this collaboration and the opportunity to further expand the potency of our proprietary TALEN® gene-editing technology to iPSCs and CAR-NKs. Down the road, this collaboration should allow for NK cell therapies to be made available to cancer patients, which is very much in line with Cellectis’ mission to provide life-saving product candidates to address unmet patient needs in this field.”

About Cellectis
Cellectis is developing the first of its kind allogeneic approach for CAR-T immunotherapies in oncology, pioneering the concept of off-the-shelf and ready-to-use gene-edited CAR T-cells to treat cancer patients. As a clinical-stage biopharmaceutical company with over 20 years of expertise in gene editing, Cellectis is developing life-changing product candidates utilizing TALEN®, its gene editing technology, and PulseAgile, its pioneering electroporation system to harness the power of the immune system in order to target and eradicate cancer cells.

As part of its commitment to a cure, Cellectis remains dedicated to its goal of providing lifesaving UCART product candidates to address unmet needs for multiple cancers including acute myeloid leukemia (AML), B-cell acute lymphoblastic leukemia (B-ALL) and multiple myeloma (MM).

Cellectis headquarters are in Paris, France, with additional locations in New York, New York and Raleigh, North Carolina. Cellectis is listed on the Nasdaq Global Market (ticker: CLLS) and on Euronext Growth (ticker: ALCLS). For more information, visit www.cellectis.com.

About Gene-Edited, iPSC-derived NK Cells
Chimeric Antigen Receptors (CAR) are fusion proteins that combine an extracellular antigen recognition domain with an intracellular co-stimulatory signaling domain. Natural Killer (NK) cells are modified genetically to allow insertion of a CAR. CAR-NK cell therapy has demonstrated initial clinical relevance without the limitations of CAR-T, such as Cytokine Release Syndrome, neurotoxicity or Graft vs Host Disease (GVHD). In addition, CAR-NKs are naturally allogeneic, available off-the-shelf and may be able to be administered on an outpatient basis. Recent innovative developments with the induced pluripotent stem cell (iPSC)-derived CAR-NKs, an innovative technology, allow large quantities of true off-the-shelf, homogeneous genetically modified CAR NK cells to be produced from a gene-edited iPSC master cell bank, and thus hold promise to expand access to cell therapy for many patients.
