Pfizer and Allogene Therapeutics Enter into Asset Contribution Agreement for Pfizer’s Allogeneic CAR T Immuno-oncology Portfolio

“While there is important work underway across the industry for next-generation autologous cell therapy, Allogene hopes to bring about the next revolution in the field with the successful development of allogeneic cell therapy and the potential for greater and faster patient access,” said Belldegrun. “Under the direction of David Chang, an extraordinary scientist, physician and life sciences business executive with over 30 years of unprecedented experience in developing cancer treatments, Allogene is poised to potentially lead the development of one of the most exciting opportunities in our industry today.”

“Last year, Kite’s anti-CD19 CAR T therapy became the first autologous CAR T treatment to be approved by the U.S. Food and Drug Administration for adult patients with aggressive non-Hodgkin lymphoma. Many believed the idea was rooted in science fiction, but science fiction became a reality,” said Chang. “We believe that this partnership among leaders in the field – visionaries, industry forerunners, venture capitalists and researchers – has the potential to accelerate the development of allogeneic T cell therapy, making it a reality and forever changing how cancer is treated.”

“Investing in innovation and R&D has long been a hallmark of who we are as investors, and for many years, we’ve been partnering with dynamic companies that are driving meaningful change in healthcare,” said Todd Sisitsky, Managing Partner, TPG Capital. “We believe CAR T is one of the most exciting spaces within the pharmaceutical landscape today, and we are thrilled to partner with a best-in-class management team and industry leaders to invest in this potentially groundbreaking opportunity.”

“As a pioneer of the allogeneic approach and expert in gene editing, the Cellectis team is excited by this agreement and eager to continue this groundbreaking work with Allogene’s experienced team, striving to accelerate the development of the portfolio and to continue along the path of making these treatments available to patients as soon as possible,” said Dr. André Choulika, Cellectis CEO.

“I believe that the recognized expertise of the Allogene team in the field of CAR T will be of benefit to the development of UCART19, for which Servier is the sponsor of two clinical studies,” commented Olivier Laureau, President of Servier Group. “The development of off-the-shelf allogeneic CAR T therapy in the field of oncology initiates a revolution that could potentially expand access of such innovative treatment to a larger number of oncologists and their patients.”

Centerview Partners is acting as financial advisor to Pfizer, with Ropes & Gray LLP acting as its legal advisor. Cooley LLP is serving as legal counsel to Allogene, Vida Venture and TPG. Gibson Dunn & Crutcher LLP are also serving as legal counsel to TPG.

Allogeneic CAR T Cell Therapies
Allogeneic CAR T cell therapies have the potential to become the next advancement in one of the most powerful anti-cancer agents, eliminating the need to create personalized therapy from a patient’s own cells. These therapies are developed from cells of healthy donors and stored for “off-the-shelf” use in patients, simplifying manufacturing process and reducing waiting time for patients.

Allogene will receive from Pfizer the rights to 16 preclinical CAR T assets licensed from Cellectis and Servier and one clinical asset licensed from Servier, UCART19, an allogeneic CAR T therapy that is being developed for treatment of CD19-expressing hematological malignancies. In partnership with Servier, UCART19 is initially being developed in acute lymphoblastic leukemia (ALL) and is currently in Phase I. UCART19 utilizes TALEN® gene editing technology pioneered and owned by Cellectis.

Allogene and Servier intend to initiate Phase 2 studies in 2019. Under the terms of the original development agreement, Allogene will have exclusive rights to develop and commercialize UCART19 in the United States, while Servier will retain exclusive rights for all other countries.

Pfizer’s Commitment to Immuno-Oncology
Immuno-Oncology (IO) is a key area of focus within Pfizer’s broad oncology portfolio, with research and development efforts spanning diverse modalities and mechanisms of action that tap into key immune system functions, harnessing the natural ability of the immune system to fight cancer. We believe that the future of IO lies in novel, biologically rational combinations based on unique tumor characteristics. We believe that Pfizer Oncology’s pipeline is in a strong position to help advance the next wave of IO science by developing new targeted therapies and IO combinations – areas in which Pfizer has a robust and proven legacy. We know that great science comes through collaboration, and we actively team up with strategic partners in IO who we believe will strengthen our portfolio and help speed innovative treatments to benefit more patients.

About Allogene Therapeutics
Allogene Therapeutics is a biotechnology company with a mission to catalyze the next revolution in cancer treatment through the development of allogeneic chimeric antigen receptor T-cell (CAR T) therapy directed at blood cancers and solid tumors. Founded and led by former Kite Pharma executives who bring unrivaled clinical development acumen in cell therapy, Allogene is well-positioned to further the potential of allogeneic cell therapy for patients.

Allogeneic CAR T therapies are engineered from cells of healthy donors and stored for “off-the-shelf” use in patients. This approach eliminates the need to create personalized therapy from a patient’s own cells, simplifies manufacturing, and reduces the time patients must wait for CAR T treatment. The Allogene portfolio includes 16 pre-clinical T cell therapy assets and UCART19, an allogeneic CAR T therapy currently in Phase 1 development for the treatment of acute lymphoblastic leukemia (ALL). Through its notable partnerships, Allogene leverages pioneering technology platforms, including TALEN^® gene editing technology, to progress its portfolio of immuno-oncology therapies. Allogene, with headquarters in San Francisco, California, is a Two River portfolio company formed with one of the largest Series A financings in biotechnology from an investment consortium that includes TPG, Vida Ventures, BellCo Capital, the University of California Office of the Chief Investment Officer and Pfizer, among others.
