"We are pleased to announce the initiation of this Phase 3 trial of pamiparib in China as a potential maintenance therapy in patients with platinum-sensitive recurrent ovarian cancer. This trial is designed to provide important confirmatory clinical data that could enable registration in the maintenance setting, as well support our planned initial regulatory submission for the treatment of patients with advanced ovarian cancer who carry a germline BRCA1/2 mutation," commented Amy Peterson, M.D., Chief Medical Officer for Immuno-Oncology of BeiGene.

"In China there are currently no approved PARP inhibitors, despite the multiple approvals of PARP inhibitors in other regions of the world and in a variety of settings. Our development program in ovarian cancer is designed to address the limited treatment options that currently exist for these patients in China," commented Lai Wang, Ph.D., Senior Vice President and Head of China Development of BeiGene.

The Phase 3 randomized, double-blind, placebo-controlled, multi-center trial is designed to evaluate the efficacy of maintenance therapy with pamiparib versus a placebo in patients with recurrent ovarian cancer who achieved a complete response or partial response after platinum-based chemotherapy, as measured by progression-free survival (PFS) determined by independent review. Secondary objectives include PFS per RECIST version 1.1 determined by investigator, overall survival, objective response rate, duration of response, time to response, safety, and tolerability. Approximately 215 patients are planned to be enrolled in this trial at 15-20 cancer centers in China.

"As we look to improve the current 30 to 40 percent five-year survival rate for patients with advanced ovarian cancer, I look forward to evaluating pamiparib as a potential new maintenance therapy. We are excited to build upon the knowledge base we have of pamiparib from its Phase 1 and 2 studies as well as from other PARP inhibitors in ovarian cancer," said Professor Ding Ma, M.D., Director of Obstetrics and Gynecology, Tongji Medical College of Huazhong University of Science and Technology; and Principal Investigator of the trial.

For more information about the trial, patients and physicians should email [email protected].

Fate Therapeutics is utilizing gene editing under its ongoing collaboration for the research and development of off-the-shelf CAR T-cell immunotherapies with Michel Sadelain, M.D., Ph.D., Director of the Center for Cell Engineering and the Stephen and Barbara Friedman Chair at MSK. At the American Society of Gene and Cell Therapy (ASGCT) (Free ASGCT Whitepaper) Annual Meeting, Dr. Sadelain will present preclinical data on FT819, an off-the-shelf, TCR-less, CD19 CAR T-cell product manufactured from a clonal master induced pluripotent stem cell (iPSC) line.

"Engineering stem cells and using master iPSC lines for the renewable production of off-the-shelf CAR T cells has the potential to advance the cancer immunotherapy landscape," said Dr. Sadelain. "We are pleased with the breakthrough discoveries accomplished under our ongoing collaboration with Fate Therapeutics, and look forward to continuing our advancement together of off-the-shelf CAR T-cell products toward clinical development."

The use of clonal master iPSC lines can overcome the complexity, heterogeneity and substantial costs associated with using cells from a patient or an allogeneic donor. Instead, iPSC-derived T-cell immunotherapies can be consistently and repeatedly mass produced and delivered in an off-the-shelf manner, significantly reducing the cost of, and time to, patient treatment.

"The use of a gene-edited master iPSC line for the manufacture of off-the-shelf T-cell immunotherapies ensures complete removal of endogenous TCR expression, which is critical to avoid the life-threatening complication of graft-versus-host disease that is seen in allogeneic T-cell therapy," said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. "The incorporation of these latest MSK technologies into our development of FT819 and our iPSC product platform advances our leadership position in developing off-the-shelf T-cell immunotherapies with improved safety, enhanced potency and expanded therapeutic reach."

Fate Therapeutics has exclusively licensed from MSK intellectual property covering the production and composition of iPSC-derived T cells for human therapeutic use. In addition, Fate Therapeutics owns an extensive intellectual property portfolio that broadly covers compositions and methods for the genome editing of iPSCs using CRISPR and other nucleases, including the use of CRISPR to insert a CAR in the TRAC locus for endogenous transcriptional control.

About FT819
FT819 is a universal, off-the-shelf, dual-targeted CAR T-cell product that is manufactured from a clonal master iPSC line. The line is engineered to completely eliminate expression of the T-cell receptor, to preferentially regulate CAR19 expression by inserting the CAR into the T-cell receptor constant (TRAC) locus, and to uniquely express a recombinant CD16 Fc receptor. In preclinical studies, FT819 exhibits a target-specific T-cell response in vitro when challenged with CD19-positive tumor cells and displays enhanced production of effector cytokines and cytolytic proteins. In addition, FT819 uniquely elicits antibody-dependent cell-mediated cytotoxicity in vitro against CD19-negative, CD20-positive tumor cells with rituximab, a monoclonal antibody targeting CD20. This dual-targeted approach of FT819 can substantially broaden the cell product’s therapeutic reach and overcome CD19 antigen escape through combination with other proven cancer treatments.

About Fate Therapeutics’ iPSC Product Platform
The Company’s proprietary iPSC product platform enables mass production of off-the-shelf, engineered, homogeneous cell products that can be administered in repeat doses to mediate more effective pharmacologic activity, including in combination with cycles of other cancer treatments. Human iPSCs possess the unique dual properties of unlimited self-renewal and differentiation potential into all cell types of the body. The Company’s first-of-kind approach involves engineering human iPSCs in a one-time genetic modification event, and selecting a single iPSC for maintenance as a clonal master iPSC line. Analogous to master cell lines used to manufacture biopharmaceutical drug products such as monoclonal antibodies, clonal master iPSC lines are a renewable source for consistently and repeatedly manufacturing homogeneous cell products in quantities that support the treatment of many thousands of patients in a cost-effective, off-the-shelf manner. Fate Therapeutics’ iPSC product platform is supported by an intellectual property portfolio of over 90 issued patents and 100 pending patent applications.

"Dedifferentiated liposarcoma is a rare and aggressive form of the disease that is resistant to both standard chemotherapy and radiation, and most patients who progress following surgery ultimately succumb to this difficult to treat cancer," said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. "We previously reported positive top-line data from the Phase 2 SEAL study in September 2017, including oral selinexor’s demonstration of superiority over placebo for the study’s primary endpoint of progression-free survival (PFS), with a hazard ratio of 0.60, representing a 40% reduction in the risk of progression or death. The Phase 3 portion of the SEAL study is currently ongoing with top-line data expected by the end of 2019. We look forward to presenting the more detailed results from the Phase 2 portion of the SEAL study at ASCO (Free ASCO Whitepaper) this year."

Details for the ASCO (Free ASCO Whitepaper) 2018 selinexor presentations are as follows:

About Selinexor

Selinexor (KPT-330) is a first-in-class, oral Selective Inhibitor of Nuclear Export / SINE compound. Selinexor functions by binding with and inhibiting the nuclear export protein XPO1 (also called CRM1), leading to the accumulation of tumor suppressor proteins in the cell nucleus. This reinitiates and amplifies their tumor suppressor function and is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. To date, over 2,400 patients have been treated with selinexor. In April 2018, Karyopharm reported positive top-line data from the Phase 2b STORM study evaluating selinexor in combination with low-dose dexamethasone in patients with penta-refractory multiple myeloma. Selinexor has been granted Orphan Drug Designation in multiple myeloma and Fast Track designation for the patient population evaluated in the STORM study. Karyopharm plans to submit a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) during the second half of 2018, with a request for accelerated approval for oral selinexor as a new treatment for patients with penta-refractory multiple myeloma. The Company also plans to submit a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) in early 2019 with a request for conditional approval. Selinexor is also being evaluated in several other mid- and later-phase clinical trials across multiple cancer indications, including in multiple myeloma in a pivotal, randomized Phase 3 study in combination with Velcade (bortezomib) and low-dose dexamethasone (BOSTON) and as a potential backbone therapy in combination with approved therapies (STOMP), and in diffuse large B-cell lymphoma (SADAL), liposarcoma (SEAL), and an investigator-sponsored study in endometrial cancer (SIENDO), among others. Additional Phase 1, Phase 2 and Phase 3 studies are ongoing or currently planned, including multiple studies in combination with one or more approved therapies in a variety of tumor types to further inform Karyopharm’s clinical development priorities for selinexor. Additional clinical trial information for selinexor is available at www.clinicaltrials.gov.
