This is the first US regulatory submission acceptance for a poly ADP-ribose polymerase (PARP) inhibitor in the 1st-line maintenance setting for advanced ovarian cancer, and if approved will be the fourth indication for Lynparza in the US.

This submission was based on positive results from the pivotal Phase III SOLO-1 trial. The trial showed a statistically-significant and clinically-meaningful improvement in progression-free survival (PFS) for Lynparza compared to placebo, reducing the risk of disease progression or death by 70% in patients with newly-diagnosed, BRCAm advanced ovarian cancer who were in complete or partial response to platinum-based chemotherapy (HR 0.30 [95% CI 0.23-0.41], p<0.001). Of those receiving Lynparza, 60% remained progression-free at 36 months compared to 27% of women in the placebo arm. These data were recently presented for the first time at the ESMO (Free ESMO Whitepaper) 2018 Congress (European Society for Medical Oncology) and published online in the New England Journal of Medicine.

Lynparza is currently approved in over 60 countries for the treatment of platinum-sensitive relapsed ovarian cancer regardless of BRCA status. It is also approved in several countries, including the US and Japan, for germline BRCAm HER2-negative metastatic breast cancer – regulatory reviews are underway in the EU, Japan and other markets.

About SOLO-1

SOLO-1 is a Phase III randomised, double-blinded, placebo-controlled, multicentre trial to evaluate the efficacy and safety of Lynparza tablets (300mg twice daily) as maintenance monotherapy compared with placebo, in newly-diagnosed patients with BRCAm advanced ovarian cancer following platinum-based chemotherapy. The trial randomised 391 patients with a deleterious or suspected deleterious BRCA1 or BRCA2 mutation who were in clinical complete or partial response following platinum-based chemotherapy. Patients were randomised (2:1) to receive Lynparza or placebo for up to two years or until disease progression (at the investigator’s discretion). The primary endpoint was PFS and key secondary endpoints included time to second disease progression or death, time to first subsequent treatment and overall survival.

About Lynparza

Lynparza (olaparib) is a first-in-class PARP inhibitor and the first targeted treatment to potentially exploit DNA damage response (DDR) pathway deficiencies, such as BRCA mutations, to preferentially kill cancer cells. Specifically, in vitro studies have shown that Lynparza-induced cytotoxicity may involve inhibition of PARP-enzymatic activity and increased formation of PARP-DNA complexes, resulting in DNA damage and cancer cell death. Lynparza is being tested in a range of DDR-deficient tumour types.

Lynparza, which is being jointly developed and commercialised by AstraZeneca and MSD, is approved for advanced ovarian cancer and metastatic breast cancer and has been used in over 20,000 patients worldwide. Lynparza has the broadest and most advanced clinical trial development programme of any PARP inhibitor and AstraZeneca and MSD are working together to understand how it may affect multiple PARP-dependent tumours as a monotherapy and in combination across multiple cancer types. Lynparza is the foundation of AstraZeneca’s industry-leading portfolio of potential new medicines targeting DDR mechanisms in cancer cells.

About ovarian cancer

Ovarian cancer is a leading cause of cancer death in women worldwide, with a five-year survival rate of 19%.[i] In 2018, there were over 295,000 new cases diagnosed and around 185,000 deaths.[ii] For newly-diagnosed advanced ovarian cancer, the primary aim of treatment is to delay progression of the disease for as long as possible and maintain the patient’s quality of life with the intent of achieving complete remission or cure.[iii],[iv],[v],[vi]

About BRCA mutations

BRCA1 and BRCA2 are human genes that produce proteins responsible for repairing damaged DNA and play an important role in maintaining the genetic stability of cells. When either of these genes is mutated, or altered, such that its protein product either is not made or does not function correctly, DNA damage may not be repaired properly, and cells become unstable. As a result, cells are more likely to develop additional genetic alterations that can lead to cancer.

On November 11, 2018 Fate Therapeutics, Inc. (NASDAQ: FATE), a clinical-stage biopharmaceutical company dedicated to the development of programmed cellular immunotherapies for cancer and immune disorders, reported new clinical data for FATE-NK100, an investigational, first-in-class, allogeneic donor-derived natural killer (NK) cell cancer immunotherapy, and provided a regulatory update on the development of FT500, a universal, off-the-shelf NK cell product candidate derived from a master induced pluripotent stem cell (iPSC) line, on November 10, 2018.

Twenty heavily pre-treated subjects, each presenting with progressive disease at the time of enrollment, have been treated with FATE-NK100 in the dose-escalation phases of three Phase 1 clinical trials. As of a October 22, 2018 data cutoff, one-month follow-up data were available on fourteen subjects1, with clinical benefit indicated in seven of these fourteen subjects:

In the DIMENSION study for the treatment of advanced solid tumors (n=5 in the monotherapy regimen; n=1 in the monoclonal antibody combination regimen1), one subject at the second dose level (1-3×107 cells per kg) and two subjects at the third dose level (3-10×107 cells per kg) treated with a single intravenous infusion of FATE-NK100 in the monotherapy regimen had stable disease at one month. These two subjects at the third dose level were each subsequently treated with a second dose of FATE-NK100 and remain on study (3.1 and 5.0 months, respectively) with ongoing disease control. The study is currently enrolling at the third dose level in the monotherapy regimen, at the second dose level in the cetuximab combination regimen (1-3×107 cells per kg) and at the run-in dose level in the trastuzumab combination regimen (1×106 cells per kg).
In the APOLLO study for the treatment of recurrent ovarian cancer (n=4), one subject treated with a single intraperitoneal infusion of FATE-NK100 at the second dose level (1-3×107 cells per kg) had stable disease at one month. The subject was subsequently treated with a second dose of FATE-NK100 and maintained disease control for 6.2 months. The study is currently enrolling at the third dose level (3-10×107 cells per kg).
In the VOYAGE study for the treatment of refractory or relapsed acute myelogenous leukemia (n=4), all three subjects treated with a single intravenous infusion of FATE-NK100 at the second dose level (1-3×107 cells/kg) showed complete clearance of leukemic blasts in the bone marrow and achieved a morphologic leukemia-free state at Day 14 following treatment. Each of these three subjects received a single dose of FATE-NK100 only, and the anti-leukemic response in each of these subjects was transient. The study is currently enrolling at the second dose level.
No dose limiting toxicities related to FATE-NK100 were reported. One serious adverse event related to FATE-NK100 was reported (Grade 3: abdominal pain) in the APOLLO study.

"The safety and clinical benefit observed with a single infusion of FATE-NK100 as a monotherapy in heavily pre-treated cancer patients, including in refractory AML patients that have high leukemic blast burden in the marrow and in advanced solid tumor patients with progressive disease, are encouraging," said Sarah Cooley, M.D., Associate Professor of Medicine, Division of Hematology, Oncology and Transplantation at the University of Minnesota and the lead investigator of the VOYAGE study. "We are particularly excited that a repeat dose of FATE-NK100 was well-tolerated and showed persistence. Importantly, all three subjects re-treated with a second dose have demonstrated disease control. These data provide compelling proof-of-concept for FATE-NK100 and support earlier intervention with NK cell therapy using a multi-dose treatment cycle."

In addition, the Company announced that adventitious agents testing of the master iPSC bank for the clinical production of FT500, a universal, off-the-shelf NK cell product candidate, has been completed. The FT500 master iPSC bank was found to be free of adventitious agents as determined by in vivo and in vitro testing. The Company has submitted these results to the U.S. Food and Drug Administration (FDA) in furtherance of the agency’s review of the Company’s FT500 Investigational New Drug (IND) application. Upon allowance by the FDA of the FT500 IND, the Company plans to initiate Phase 1 clinical testing of FT500 as a monotherapy and in combination with checkpoint inhibitor therapy for the treatment of advanced solid tumors. This first-in-human study is expected to evaluate the safety and tolerability of multiple doses of FT500 in multiple dosing cycles.

An updated presentation on the Company’s NK cell cancer immunotherapy franchise can be found under "Events & Presentations" in the Investors and Media section of the Company’s website at www.fatetherapeutics.com.

1 Excludes one subject treated at the run-in dose level in the cetuximab combination regimen (1×106 cells per kg)

About FATE-NK100
FATE-NK100 is an investigational, first-in-class, allogeneic donor-derived natural killer (NK) cell cancer immunotherapy comprised of adaptive memory NK cells, a highly specialized and functionally distinct subset of activated NK cells expressing the maturation marker CD57. Higher frequencies of CD57+ NK cells in the peripheral blood or tumor microenvironment in cancer patients have been linked to better clinical outcomes. In August 2017, non-clinical data describing the unique properties and anti-tumor activity of FATE-NK100 were published by Cancer Research (doi:10.1158/0008-5472.CAN-17-0799), a peer-reviewed journal of the American Association of Cancer Research. Three clinical trials of FATE-NK100 are currently being conducted: VOYAGE for the treatment of refractory or relapsed acute myelogenous leukemia; APOLLO for the treatment of recurrent ovarian cancer; and DIMENSION for the treatment of advanced solid tumors, including in combination with monoclonal antibody therapy.

On November 11, 2018 Generon Corporation, a leading biopharmaceutical company in China, reported it received approval for the Company’s Investigational New Drug (IND) application from the State Food and Drug Administration (SFDA) of the People’s Republic of China to initiate a Phase I clinical trial for A-319 in patients with B cell malignancies (Press release, Generon (Shanghai), NOV 11, 2018, View Source [SID1234531111]). A-319 is Generon’s second bispecific antibody in clinical development.

A-319 is the first CD19 engaging bispecific antibody approved by the SFDA for clinical trials in China. The CD3/CD19 bispecific antibody was developed using Generon’s Immuno-Therapy Antibody (ITab)TM technology platform. The IND approval enables Generon to commence Phase I clinical trials in China enrolling patients with B cell malignancies including acute lymphoblastic leukemia (ALL) and B cell lymphoma.

Dr. Mi Jian Qing, Professor at Ruijin Hospital, Shanghai Jiaotong University expressed his enthusiasm about the biology of A-319 and the potential benefits for ALL patients. He commented: "Obtaining the SFDA’s approval for the A-319 Phase I trial is a significant accomplishment for Generon’s ITabTM platform. The IND approval is another step in demonstrating Generon’s innovative capabilities".

Yifan Pharmaceuticals, Generon’s parent company, congratulated Generon’s team on the continued effort to develop innovative therapies. Dr. Xiao Qiang Yan, CEO and CSO of Generon, said, "Initiation of a Phase I study for A-319 in China is one of Generon’s goals this year. A-319 has a similar mechanism of action to eliminate malignant B cells to those of CAR-T and other CD19/CD3 bispecific antibodies, but it is more convenient for patient dosing and potentially with better safety. A-319 is our second T-cell activating bispecific antibody to enter clinical development. Generon is expanding its ITabTM pipeline for both liquid and solid tumors and committed to bringing innovative immune-oncology antibodies to cancer patients in China and the world".

B cell malignancies

B cell malignancies refer to the different types of cancers that form in B cells in the immune system, including B-cell lymphomas and B-cell leukemia. B-cell lymphoma may be either indolent (slow-growing) or aggressive (fast-growing). Most B-cell lymphomas are non-Hodgkin lymphomas (NHL). There are many different types of B-cell non-Hodgkin lymphomas including chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), Burkitt lymphoma (BL), diffuse large B-cell lymphoma (DLBL), follicular lymphoma (FL), and mantle cell lymphoma (MCL). B-cell leukemia includes B-cell chronic lymphocytic leukemia (CLL), Acute lymphoblastic leukemia (ALL), B-cell prolymphocytic leukemia (PLL), and hairy cell leukemia (HCL). The prognosis and treatment of B cell malignancies depend on the specific type of the B cell lymphoma/leukemia, as well as the stage and grade. Recent immunotherapy (T-cell activating) approaches have demonstrated significant clinical benefits for patients.

About A-319

A-319 is a T-cell activating bispecific antibody (BsAb) designed to target CD19 and CD3 (anti-CD19, anti-CD3) and is under development for the treatment of patients with B cell malignancies including B-cell leukemia and B-cell lymphoma. A-319 activates T lymphocytes in a patient to kill CD19 expressing malignant B-cells.

Harpoon’s TriTAC platform was designed to advance the therapeutic potential of T cell engagers, with a long half-life extended format. Harpoon is developing a pipeline of four wholly owned TriTAC product candidates. Harpoon’s lead product candidate, HPN424, is currently in a Phase 1 clinical trial for the treatment of metastatic castration-resistant prostate cancer, or mCRPC.

"This financing is a significant milestone for us as we continue to advance our pipeline, including HPN424, our lead product candidate, with which we initiated a Phase 1 trial this summer as a potential treatment for prostate cancer," said Jerry McMahon, Ph.D., President and Chief Executive Officer. "With these funds, we intend to pursue preclinical and clinical development of additional product candidates based on our TriTAC platform as well as our second technology platform, ProTriTAC, which we believe can expand access to a broader landscape of tumor targets and indications."

"Harpoon has assembled a world-class team to drive forward an ambitious pipeline across a range of indications and patient populations," said Luke Evnin, Ph.D., Co-Founder and Chairman of Harpoon and Founder and Managing Director at MPM Capital. "With this financing, we believe we have the capacity not only to advance those pipeline programs but also to continue to innovate in the immuno-oncology arena."

In addition, in 2019, Harpoon plans to initiate Phase 1 clinical trials for HPN536 (a mesothelin-targeting TriTAC) for the treatment of mesothelin-expressing tumors, and HPN217 (a BCMA-targeting TriTAC) for the treatment of multiple myeloma. The ProTriTAC platform effort is yielding T-cell engagers against additional targets based on tumor protease-dependent activation in the tumor microenvironment, and Harpoon expects to advance its first ProTriTAC product candidate to IND-enabling studies in 2019.
