"NK cells have the inherent ability to target a diversity of stress-induced ligands on tumor cells and can be safely administered without the need for individualized patient matching. Additionally, NK cells engineered with chimeric antigen receptors can be targeted to tumors with high specificity. This duality provides CAR NK cells with the unique potential to overcome antigen escape and address tumor heterogeneity, which are distinct advantages over patient-specific CAR T-cell immunotherapies," said Dr. Kaufman. "We have now identified several CAR constructs optimized for NK cell signaling, persistence and cytotoxicity, and combined our targeting content with Fate Therapeutics’ induced pluripotent stem cell product platform for development of off-the-shelf CAR-targeted NK cell products using clonal engineered master pluripotent cell lines."

The CAR constructs identified by the collaborators contain transmembrane and co-stimulatory domains that enhance antigen-specific NK cell activation and improve the effector function of NK cells. Fate Therapeutics holds an exclusive license to the intellectual property covering these CAR constructs and maintains an option to exclusively license intellectual property arising from all research and development activities under the collaboration.

At the 59th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition, Dr. Kaufman and Fate Therapeutics will present preclinical data on Saturday, December 9, 2017 highlighting CAR-targeted NK cells derived from an induced pluripotent stem cell (iPSC) engineered with a specific CAR construct containing a NKG2D transmembrane domain, a 2B4 co-stimulatory domain and a CD3ζ signaling domain. In preclinical studies using an ovarian cancer xenograft model, the collaborators have shown that a single dose of CAR-targeted NK cells derived from iPSCs engineered with this specific CAR construct markedly inhibited tumor growth and significantly enhanced survival as compared to NK cells containing a CAR construct commonly used for T-cell immunotherapy. Dr. Kaufman was recently awarded $5.15 million by the California Institute for Regenerative Medicine (CIRM) to advance clinical translation of NK cells derived from pluripotent stem cells into a standardized treatment for treating hematologic malignancies.

iPSCs possess the unique dual properties of unlimited self-renewal and differentiation potential into all cell types of the body. The engineering of iPSCs can be done as a one-time genetic modification event and a single iPSC can be selected for creation of a clonal master pluripotent cell line. Similar to master cell lines used for the manufacture of therapeutic antibodies, a clonal master pluripotent cell line can be used to repeatedly create clonal populations of effector cells. This first-of-kind approach enables large-scale generation of off-the-shelf, targeted, 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.

About Calquence

Calquence (acalabrutinib; previously known as ACP-196) is a selective inhibitor of BTK. Calquence binds covalently to BTK, irreversibly inhibiting its activity, and has demonstrated this with minimal interactions with other immune cells in pre-clinical studies.5 In B cells, BTK signalling results in activation of pathways necessary for B-cell proliferation, trafficking, chemotaxis and adhesion.1

The recommended dose of Calquence is one 100mg capsule taken orally approximately every twelve hours until disease progression or unacceptable toxicity.1 Calquence may be taken with or without food.1

Calquence is also in development for the treatment of multiple B-cell malignancies and other cancers including 1st-line MCL, chronic lymphocytic leukaemia (CLL), Waldenström macroglobulinemia (WM), follicular lymphoma, diffuse large B-cell lymphoma, and multiple myeloma. It is also being developed as a monotherapy and in combination trials for solid tumours. More than 35 clinical trials across 40 countries with more than 2,500 patients are underway or have been completed.

Calquence was granted Orphan Drug Designation by the US FDA for the treatment of adult patients with MCL in September 2015 and by the European Commission in March 2016 for the treatment of adult patients with CLL, MCL and WM.

Foundation Medicine and Collaborators to Present New Data at the American Society of Hematology (ASH) Annual Meeting that Supports Use of FoundationOne®Heme to Advance Personalized Medicine in Blood Cancers

On December 6, 2017 Foundation Medicine, Inc. (NASDAQ:FMI) reported that new data generated with FoundationOneHeme, its comprehensive genomic profiling (CGP) assay for hematologic malignancies and sarcomas, will be presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting (Press release, Foundation Medicine, DEC 6, 2017, View Source [SID1234522397]). Data from a broad range of blood cancers, including acute myeloid leukemia (AML), myeloproliferative neoplasms (MPN), and non-Hodgkin lymphoma (NHL), including primary central nervous system lymphoma (PCL), demonstrate the value of integrating FoundationOneHeme into clinical care. The data presented is expected to demonstrate the potential for CGP to improve disease classification, to offer personalized prognostic information and to support therapeutic treatment decision making by informing treating physicians about the use of novel treatment options, including cancer immunotherapies.

"Comprehensive genomic profiling (CGP) is proving to be an essential component for personalized cancer care, particularly as we learn more about the diverse genomic alterations in blood cancers," said Vincent Miller, M.D., chief medical officer at Foundation Medicine. "FoundationOneHeme is at the forefront of helping to identify new treatment approaches, including cancer immunotherapy, for individuals with blood cancers. Our new findings to be presented at ASH (Free ASH Whitepaper) support the ability of CGP to address high unmet medical needs across a wide range of hematologic malignancies, including rare conditions for which there are few treatment options."

Cancer immunotherapy is emerging as a therapeutic tool for patients with diverse hematologic malignancies. New results to be presented at ASH (Free ASH Whitepaper) using FoundationOneHeme show that more than one-quarter of patients with PCL had high tumor mutational burden (TMB), a genomic biomarker that has been shown across several cancer types to predict response to immuno-oncology treatment strategies, such as checkpoint inhibitors. Less than 50 percent of PCL patients achieve complete remission with current standard of care treatments, underscoring a need for new treatment options for these patients.

New results also support the role of FoundationOneHeme to guide therapy selection and predict response to treatment. In an oral study to be presented, FoundationOneHeme detected NTRK fusions in a wide variety of hematologic malignancies, and clinical response to a TRK inhibitor was subsequently observed in a patient with refractory AML and an ETV6-NTRK2 fusion. In another study to be presented, CGP offered insights that may facilitate risk-adapted clinical management decisions in patients with intermediate-and favorable-risk AML, potentially informing optimal use of autologous stem cell transplantation (auto-SCT) over conventional consolidation chemotherapy. For example, the study showed the presence of PTPN11 mutations to predict long term clinical outcomes following an auto-SCT.

Other results to be presented at ASH (Free ASH Whitepaper) demonstrate the ability of FoundationOneHeme to detect both known and novel BCL6 rearrangements in NHL, including cases that previously tested negative with standard-of-care single marker testing. BCL6 rearrangements have known diagnostic and prognostic utility in specific subtypes of NHL.

Foundation Medicine and collaborators will present a total of nine studies, including four oral presentations and five poster presentations, at the ASH (Free ASH Whitepaper) Annual Meeting from December 9-12, 2017 in Atlanta. The planned presentations are as follows:
