"Combination therapy of rituximab and chemotherapy has been used as the standard treatment for CD20-positive B-cell FL for a long time. As a new treatment option, Obinutuzumab was confirmed to be more beneficial than the conventional treatment with rituximab for the treatment of FL," said Dr. Yasushi Ito, Chugai’s Senior Vice President, Head of Project & Lifecycle Management Unit. "We are committed to deliver obinutuzumab to patients as early as possible to contribute to the access to better treatments in Japan."

Dr. Kazuya Mori, Nippon Shinyaku’s Corporate Officer, Head of R&D Administration Div. said "I am very glad that a new drug application for our co-developed product, obinutuzumab, was filed. By adding this new product to our lineup in the area of hematologic malignancies, on which we are focusing, we will make utmost efforts to meet the demands of the clinical setting and contribute to the treatment of patients."

This filing was based on the results of the GALLIUM study, a global phase III clinical study conducted by Roche and participating from Japan and other several clinical studies.
The GALLIUM study is a global Phase III open-label, multi-center, randomized two-arm study that evaluated the efficacy and safety of obinutuzumab plus chemotherapy followed by obinutuzumab alone (obinutuzumab arm) compared with rituximab plus chemotherapy followed by rituximab alone (rituximab arm) in 1,401 patients with previously untreated CD20-positive advanced non-Hodgkin’s lymphoma. The primary endpoint of the study was investigator-assessed progression free survival (PFS) in 1,202 patients with FL. The secondary endpoints were PFS assessed by an independent review committee (IRC), overall survival (OS), safety, and other endpoints.

With respect to the primary endpoint, as the median PFS was not reached, the results showed that obinutuzumab arm reduced the risk of disease progression, recurrence or death in patients with FL by 34 percent (HR=0.66, 95% CI: 0.51-0.85, p=0.0012, stratified log-rank test, Data cut-off: January 31, 2016) compared to rituximab arm. Concerning secondary endpoints, the median PFS assessed by the IRC was not reached as well, the risk of disease progression, recurrence or deaths decreased by 29% (HR=0.71, 95% CI: 0.54-0.93], p=0.0138, stratified log-rank test, Data cut-off: January 31, 2016). The median OS did not reach in both arms due to small numbers of events. As for safety, the adverse events (AEs) expressed in both arms in the GALLIUM study were consistent with previous reports. The Grade 3 or higher AEs which was observed in 5% or more frequently for obinutuzumab arm than rituximab arm was neutropenia (43.9% for obinutuzumab arm vs. 37.9% for rituximab arm).

Obinutuzumab is a glycoengineered type II anti-CD20 monoclonal antibody designed to attach to CD20, a protein expressed on certain B cells, but not on stem cells or plasma cells, same as rituximab which is recommended as a treatment of non-Hodgkin’s lymphoma in treatment guidelines in Japan and overseas. Obinutuzumab is designed to attack and destroy targeted B-cells both directly and together with the body’s immune system.

In Japan, the prevalence of malignant lymphoma was reported to be approximately 27,000 and the number of deaths due to the disease was reported to be approximately 11,000 in 20121, 2). Since the cases of Hodgkin’s lymphoma is reported to account for approximately 8 to 10% of the cases of malignant lymphoma in Japan3), the prevalence of non-Hodgkin’s lymphoma is estimated to be approximately 24,000 and the number of deaths from this condition is estimated to be approximately 10,000. The prevalence of and deaths from malignant lymphoma tend to increase in recent years1, 2), and a same tendency is seen in patients with non-Hodgkin’s lymphoma.

Chugai and Nippon Shinyaku will work for the early approval to provide obinutuzumab as a new treatment option for patients with CD20-positive B-cell follicular lymphoma and medical professionals.

On August 21, 2017 Syros Pharmaceuticals (NASDAQ: SYRS), a biopharmaceutical company pioneering the discovery and development of medicines to control the expression of disease-driving genes, reported that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation to SY-1425 for the treatment of acute myeloid leukemia (AML) (Press release, Syros Pharmaceuticals, AUG 21, 2017, View Source [SID1234520301]). SY-1425, an oral first-in-class selective retinoic acid receptor alpha (RARα) agonist, is currently in a Phase 2 clinical trial in genomically defined subsets of patients with AML and myelodysplastic syndrome (MDS).

"Treatment of AML remains a significant unmet medical need, with many patients lacking adequate therapeutic options," said David A. Roth, M.D., Syros’ Chief Medical Officer. "We believe that SY-1425 may provide a meaningful benefit for subsets of AML patients whose disease is driven by abnormally high expression of the RARA or IRF8 genes. Receiving orphan drug designation is an important regulatory milestone in the development of SY-1425. We’re pleased with the continued progress of the ongoing Phase 2 clinical trial, and we look forward to presenting initial clinical data in the fourth quarter of this year."

The FDA’s Office of Orphan Drug Products grants orphan status to support development of medicines for the treatment of rare diseases that affect fewer than 200,000 people in the United States. Orphan drug designation may provide certain benefits, including a seven-year period of market exclusivity if the drug is approved, tax credits for qualified clinical trials and an exemption from FDA application fees.

Using its gene control platform, Syros discovered subsets of AML and MDS patients with super-enhancers associated with RARA or IRF8. Syros identified proprietary biomarkers related to these super-enhancers. These super-enhancers are believed to drive overexpression of the RARA or IRF8 genes, locking cells in an immature, undifferentiated and proliferative state, leading to disease. In preclinical studies, SY-1425 promoted differentiation of AML cells with high RARA or IRF8 expression and inhibited tumor growth and prolonged survival in patient-derived xenograft models of AML with high RARA expression. Syros estimates that about one-third of AML and MDS patients have either the RARA or IRF8 biomarker, or both.

The ongoing Phase 2 clinical trial of SY-1425 is assessing the safety and efficacy of SY-1425 as a single agent in four AML and MDS patient populations, as well as in combination with azacitidine, a standard-of-care therapy, in newly diagnosed AML patients who are not suitable candidates for standard chemotherapy. All patients in the trial are prospectively selected using biomarkers for high expression of RARA or IRF8. Additional details about the trial can be found using the identifier NCT02807558 at www.clinicaltrials.gov.

On August 21, 2017 Blueprint Medicines Corporation (NASDAQ: BPMC), a leader in discovering and developing targeted kinase medicines for patients with genomically defined diseases, reported that updated data from its ongoing Phase 1 clinical trial evaluating BLU-554 in patients with advanced hepatocellular carcinoma (HCC) will be presented in oral presentations at the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) 2017 Congress on September 10, 2017 in Madrid, Spain and at the 11th International Liver Cancer Association (ILCA) Annual Conference on September 17, 2017 in Seoul, South Korea (Press release, Blueprint Medicines, AUG 21, 2017, View Source;p=irol-newsArticle&ID=2294896 [SID1234520303]). BLU-554 is a potent and highly selective inhibitor of FGFR4.

At ESMO (Free ESMO Whitepaper) and ILCA, Blueprint Medicines anticipates presenting updated safety and clinical activity data from its ongoing Phase 1 clinical trial of BLU-554. As of the most recent data cutoff date of August 18, 2017, 38 patients with FGFR4 pathway activation, as indicated by FGF19 overexpression, were evaluable for clinical activity, and an objective response rate of 16 percent (95 percent confidence interval 6-31 percent) was observed in this population.

"The preliminary BLU-554 data announced today continue to provide support for selective FGFR4 inhibition as a novel targeted treatment approach in biomarker-selected patients with hepatocellular carcinoma," said Andy Boral, M.D., Ph.D., Chief Medical Officer of Blueprint Medicines. "As we evaluate the results for BLU-554 in the context of historical data for currently approved therapies showing response rates of less than 10 percent, we are encouraged that radiographic tumor reductions were observed in a refractory population with progressive disease and few or no remaining therapeutic options. We look forward to sharing a comprehensive update on the ongoing BLU-554 clinical trial, as well as the path forward for further development, in September."

About GLS-010

GLS-010, also referred to as WBP3055, is an investigational fully human monoclonal antibody that belongs to a class of immuno-oncology agents known as immune checkpoint inhibitors. It is designed to bind to PD-1, a cell surface receptor that plays an important role in the downregulation of the immune system by preventing the activation of T-cells. Other anti-PD-1 antibodies have been approved by the US FDA in multiple cancer settings. It is estimated that more than 500 clinical trials are ongoing to continue to investigate this class of biologics for more than 20 different cancer indications.

On August 17, 2017 Atreca, Inc., a biotechnology company focused on developing novel therapeutics based on a deep understanding of the human immune response, reported the completion of its Series B round of financing with a total investment of $35 million (Press release, Atreca, AUG 17, 2017, View Source [SID1234522949]). The financing was co-led by new investor Wellington Management Company LLP and by a large US-based, healthcare-focused fund, participating as an existing Atreca investor. Additional participation included new investor Cormorant Asset Management, based in Boston, as well as other new and existing investors.

Proceeds from the financing will be used to accelerate and broaden Atreca’s discovery and development of antibody-based therapeutics that initiate, shape, and drive the anti-tumor immune response in cancer patients, as enabled by the Company’s proprietary Immune Repertoire Capture (IRC) technology. Atreca’s technology provides unbiased and virtually error-free antibody and T cell receptor (TCR) sequences at high throughput from single B and T cells of active human immune responses, enabling the identification, generation, and analysis of functional human antibodies and TCRs directly from such responses.

"We are very pleased with the continued support of our existing investors, as well as the commitment of our new, high-caliber investors," said Tito A. Serafini, Ph.D., Atreca’s President, Chief Executive Officer, and Co-Founder. "With their participation, we continue to build a foundation for long-term growth. This funding enables us to accelerate the acquisition of immune response data central to cancer immunotherapy and to expand and advance our pipeline of novel antibody therapeutics based on those data." To date, Atreca has built a library of over 400 patient-derived antibodies that bind non-autologous tumor tissue as the foundation for its pipeline and anticipates nominating a clinical candidate in its lead oncology program by the end of the year.

"Atreca’s novel and differentiated approach has the potential to address broad, compelling unmet needs in diverse immuno-oncology applications, a global market that is anticipated to exceed more than $100 billion within five years," said Brian Atwood, Atreca’s Chairman. "We are excited by the Company’s continued momentum and the top-tier financing syndicate participating in the Series B round."
