Pfizer Inc. (NYSE:PFE) and Allogene Therapeutics, Inc. (Allogene) today announced that the two companies have entered into an asset contribution agreement for Pfizer's portfolio of assets related to allogeneic chimeric antigen receptor T cell (CAR T) therapy, an investigational immune cell therapy approach to treating cancer.

Allogene, co-founded and led by former executives of Kite Pharma, is ideally positioned to catalyze the development of this allogeneic cell therapy portfolio. Arie Belldegrun, M.D., FACS, Founder and former Chairman, President and Chief Executive Officer of Kite, will serve as Executive Chairman, and David Chang, M.D., Ph.D., former Executive Vice President, Research and Development and Chief Medical Officer of Kite, will serve as President and Chief Executive Officer.

Pfizer views this agreement as an attractive opportunity to support the continued development of allogeneic CAR T therapy in a highly focused and skilled manner. Pfizer will continue to participate financially in the development of the CAR T portfolio through a 25 percent ownership stake in Allogene. Separately, Pfizer continues to have an 8 percent ownership stake in Cellectis through an equity agreement entered into in 2014. Allogene, a Two River portfolio company, was formed with Series A financing of $300 million 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. TPG, Vida Ventures, BellCo Capital and Pfizer will be represented on the Allogene Board of Directors. Closing is expected in the second quarter of 2018, subject to closing conditions.

"The allogeneic CAR T platform represents a potentially transformative approach to treating cancer, and we are very excited about what the future may hold for this area of research," said Robert Abraham, Senior Vice President and Group Head, Oncology Research & Development, Pfizer. "We believe that under the strong scientific, clinical development and regulatory expertise of Allogene's leadership team, the portfolio of CAR T assets contributed by Pfizer will be well-positioned to rapidly advance into potential innovative new therapies, and ultimately to reach patients in need more quickly."

"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.
