Iovance Biotherapeutics and Cellectis have signed a research partnership and an exclusive global license agreement

13 January 2020

Iovance Biotherapeutics, Inc., an advanced phase biotechnology company developing new T-cell based cancer immunotherapies, and Cellectis, a clinical phase biopharmaceutical company specializing in the development of immunotherapies based on genetically modified allogeneic CAR-T cells (UCART), have announced the signing of a research partnership and an exclusive global license agreement granting at Iovance a license for certain applications of Cellectis TALEN® technology to develop tumor infiltrating lymphocytes (TIL) which have been genetically modified to create more powerful cancer therapies.

This global license grants Iovance Biotherapeutics the exclusive use of TALEN® technology targeting several genes to modify TILs for therapeutic purposes in various types of cancer. The financial conditions of this license provide for payments from Iovance Biotherapeutics to Cellectis at the development, regulatory and sales stages, as well as royalties on the net sales of TIL products modified using TALEN® technology.

“We are delighted to collaborate with Cellectis to apply the TALEN® genome editing technology to Iovance's TIL products. We believe that we can genetically modify the TILs to obtain an anti-cancer product that is more reactive to tumors, ”explains Maria Fardis, President and CEO of Iovance Biotherapeutics. “We plan to bring a modified TIL therapy using TALEN® technology to the clinic as soon as possible. "

"We are delighted to work with Iovance and are convinced that the application of our TALEN® technology to its TIL-based products will generate better treatments for various types of cancer," added André Choulika, President and CEO of Cellectis. "Patients remain the primary concern of our company and we sincerely hope that this collaboration will find more effective solutions for those who need them." "

About Iovance Biotherapeutics

Iovance Biotherapeutics aims to improve patient care by making T-cell based immunotherapies widely available for the treatment of patients with solid tumors and blood cancers. Tumor infiltrating therapy (TIL) uses a patient's own immune cells to attack cancer cells. TIL cells are extracted from the patient's tumor tissue, multiplied by an exclusive process, and then re-infused into the patient. After the infusion, the TILs reach the tumor tissue, where they attack the tumor cells. The company is currently conducting pivotal studies in patients with metastatic melanoma or advanced cervical cancer. The company's TIL therapies are also being evaluated for the treatment of patients with advanced local, recurrent or metastatic cancers, including head and neck cancer, and non-small cell lung cancer. A clinical study to determine the effectiveness of Iovance T cell therapy on blood cancers, called peripheral blood lymphocyte therapy (PBL), is being launched. For more information, .

About Cellectis

Cellectis is developing the very first allogenic immunotherapies based on CAR-T cells, inventing the concept of CAR-T cells engineered on the shelf and ready to use for the treatment of cancer patients. By capitalizing on its 20 years of genome engineering expertise, on its TALEN® genome editing technology and on the pioneering PulseAgile electroporation technology, Cellectis is developing innovative product candidates using the power of the immune system to target and eliminate cancer cells.

As part of its commitment to the research of cancer therapies, Cellectis aims to develop UCART product candidates likely to save the lives of patients suffering from certain types of cancer, in particular acute myeloid leukemia, acute lymphoblastic cell leukemia B, multiple myeloma and Hodgkin and non-Hodgkin lymphoma.

Cellectis' head office is located in Paris. Cellectis is also located in New York and Raleigh in the United States. Cellectis is listed on the Euronext Growth market (code: ALCLS) as well as on the Nasdaq Global Market (code: CLLS). To find out more, visit our website: .
