"We’re excited that the NDAs for both zanubrutinib and tislelizumab are receiving priority review by the NMPA," commented Wendy Yan, Senior Vice President, Global Head of Regulatory Affairs at BeiGene. "We look forward to working closely with the NMPA and CDE in the coming months and hope to bring more treatment options to cancer patients."

Zanubrutinib and tislelizumab were both discovered in BeiGene’s research facilities in Beijing, China. Zanubrutinib is being developed globally by BeiGene as a monotherapy and in combination with other therapies to treat various hematologic malignancies. The NDAs for zanubrutinib as a potential treatment for patients with R/R MCL and for patients with R/R chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) were accepted by the NMPA in August and October 2018, respectively. Tislelizumab is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid and hematologic cancers. The NDA for tislelizumab as a potential treatment for patients with R/R cHL was accepted by the NMPA in August 2018.

Priority review and approval was established in China to facilitate drug registration management and accelerate the development of new drugs with clinical value under the guidance of Opinions on the Reform of the Review & Approval System for Drugs and Medical Devices issued by the State Council in August 2015, and Opinions on Encouraging Pharmaceutical Innovation via Priority Review & Approval issued by CFDA in December 2017. According to these guidelines, the regulatory authority will prioritize the review process and evaluation resources for applications under priority review should expect prioritized review and inspection resource and reduced review and approval timelines.

About Zanubrutinib
Zanubrutinib (BGB-3111) is an investigational small molecule inhibitor of Bruton’s tyrosine kinase (BTK). Zanubrutinib was discovered in BeiGene’s research facilities in Beijing, China, and is being developed globally by BeiGene as a monotherapy and in combination with other therapies to treat various hematologic malignancies.

About Tislelizumab
Tislelizumab (BGB-A317) is an investigational humanized monoclonal antibody that belongs to a class of immuno-oncology agents known as immune checkpoint inhibitors. Discovered by BeiGene scientists in Beijing, tislelizumab is designed to bind to PD-1, a cell surface receptor that plays an important role in downregulating the immune system by preventing the activation of T-cells. Tislelizumab has demonstrated high affinity and specificity for PD-1 in pre-clinical studies. It is potentially differentiated from the currently approved PD-1 antibodies in an engineered Fc region, which is believed to minimize potentially negative interactions with other immune cells, based on preclinical data. Tislelizumab is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers. BeiGene and Celgene Corporation have a global strategic collaboration for the development of tislelizumab in solid tumor cancers outside of Asia (except Japan).

Exelixis’ Partner Ipsen Receives European Commission Approval for CABOMETYX® (cabozantinib) Tablets for the Treatment of Hepatocellular Carcinoma in Adults Previously Treated with Sorafenib

On November 15, 2018 Exelixis, Inc. (Nasdaq: EXEL) reported that its partner Ipsen received approval from the European Commission (EC) for CABOMETYX (cabozantinib) tablets as a monotherapy for hepatocellular carcinoma (HCC) in adults who have previously been treated with sorafenib (Press release, Exelixis, NOV 15, 2018, View Source;p=irol-newsArticle&ID=2377258 [SID1234531351]). This approval allows for the marketing of CABOMETYX in this indication in all 28 member states of the European Union, Norway and Iceland.

"The approval of CABOMETYX in the Europe Union is a very important milestone for our partner Ipsen and marks significant progress for people living with liver cancer, which is the second-leading cause of cancer death worldwide," said Michael M. Morrissey, Ph.D., President and Chief Executive Officer of Exelixis. "This patient community is in dire need of new options to treat this aggressive disease, and we are excited to work with Ipsen to make this treatment available to patients in the European Union and other countries worldwide."

Under the terms of the Collaboration Agreement with Ipsen, Exelixis will receive a milestone payment of $40 million for the approval of the second-line treatment of HCC. This milestone will be paid by Ipsen within the next 70 days.

"Today’s European Commission approval of CABOMETYX provides a much-needed new option for HCC patients. Until now, physicians in Europe had only one approved therapy for the second-line treatment of this aggressive and difficult-to-treat cancer. We are proud to offer CABOMETYX as an innovative treatment that has been shown to extend survival in previously treated patients with HCC," said Harout Semerjian, Chief Commercial Officer of Ipsen. "This new indication reinforces Ipsen’s commitment to improving patients’ lives through the expansion of the clinical benefit of CABOMETYX in the treatment of solid tumors."

The EC approval is based on results from the CELESTIAL trial of CABOMETYX in patients with advanced HCC who received prior sorafenib. In this phase 3 pivotal trial, CABOMETYX demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS) versus placebo. CABOMETYX is also approved in the European Union for the treatment of advanced renal cell carcinoma (RCC) in adults who have received prior VEGF-targeted therapy and for previously untreated intermediate- or poor-risk advanced RCC.

On May 29, 2018, Exelixis announced that the U.S. Food and Drug Administration (FDA) accepted for filing the supplemental New Drug Application (sNDA) for CABOMETYX for previously treated advanced HCC and assigned a Prescription Drug User Fee Act action date of January 14, 2019. An sNDA is an application to the FDA that, if approved, will allow a drug sponsor to make changes to a previously approved product label, including modifications to the indication.

About the CELESTIAL Study

CELESTIAL is a randomized, double-blind, placebo-controlled study of cabozantinib in patients with advanced HCC conducted at more than 100 sites globally in 19 countries. The trial was designed to enroll 760 patients with advanced HCC who received prior sorafenib and may have received up to two prior systemic cancer therapies for HCC and had adequate liver function. Enrollment of the trial was completed in September 2017. Patients were randomized 2:1 to receive 60 mg of cabozantinib once daily or placebo and were stratified based on etiology of the disease (hepatitis C, hepatitis B or other), geographic region (Asia versus other regions) and presence of extrahepatic spread and/or macrovascular invasion (yes or no). No cross-over was allowed between the study arms during the blinded treatment phase of the trial. The primary endpoint for the trial is OS, and secondary endpoints include objective response rate and PFS. Exploratory endpoints include patient-reported outcomes, biomarkers and safety.

In October 2017, Exelixis announced that the independent data monitoring committee for the CELESTIAL study recommended that the trial be stopped for efficacy following review at the second planned interim analysis, with cabozantinib providing a statistically significant and clinically meaningful improvement in OS compared with placebo in patients with previously treated advanced HCC. The data, originally presented at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper)’s Gastrointestinal Cancers Symposium (ASCO-GI) in January 2018, were published in The New England Journal of Medicine in July 2018.1

About HCC

Liver cancer is the second-leading cause of cancer death worldwide, accounting for more than 700,000 deaths and 800,000 new cases each year.2 In the U.S., the incidence of liver cancer has more than tripled since 1980.3 HCC is the most common form of liver cancer, making up about three-fourths of the estimated nearly 42,000 new cases in the U.S. in 2018.3 HCC is the fastest-rising cause of cancer-related death in U.S.4 Without treatment, patients with advanced HCC usually survive less than 6 months.5

Akari Announces Third Quarter 2018 Financial Results and Business Highlights

On November 15, 2018 Akari Therapeutics, Plc (NASDAQ:AKTX), a biopharmaceutical company focused on innovative therapeutics to treat orphan autoimmune and inflammatory diseases where complement and or leukotriene systems are implicated, reported its financial results for the third quarter ended September 30, 2018 (Press release, Akari Therapeutics, NOV 15, 2018, View Source [SID1234531344]).

"We are focused on moving our four priority clinical programs forward and expect initial data from our trials in patients with bullous pemphigoid (BP) and atopic keratoconjunctivitis (AKC) in the first quarter of 2019," commented Clive Richardson, Interim Chief Executive Officer of Akari Therapeutics.

Clinical development highlights and upcoming milestones

Coversin clinical trials focused on orphan diseases mediated by both the complement and leukotriene pathways with initial data readouts expected in the first quarter 2019:
Phase II trial in patients with BP, a severe blistering skin disease
Phase I/II trial in patients with AKC, a sight-threatening surface of the eye condition
Coversin clinical trials in orphan diseases in which complement dysregulation is the primary disease driver:
Two trials open in PNH: a Phase III trial in naïve patients and a Phase II trial in patients who are resistant to eculizumab
An open Phase II trial in atypical hemolytic syndrome (aHUS), a severe thrombotic microangiopathy
Ongoing named patient program in pediatric patients with thrombotic microangiopathy (TMA) post bone marrow transplant
Long-term safety study for Coversin
Total cumulative number of patient-years on Coversin treatment approximately 15 years
All patients in the long term study have now been treated for more than 15 months and the first patient has now been treated for 34 months
No drug related serious adverse events and no neutralizing antibodies reported to date
Six PNH patients were transfusion dependent prior to treatment with Coversin, of which four in the long-term study are now transfusion independent; two remain on transfusion.
Third Quarter 2018 Financial Results

Research and development (R&D) expenses in the third quarter of 2018 were $3.3 million, as compared to $6.4 million in the same quarter the prior year. The decrease was due primarily to lower manufacturing costs for Coversin as the Company had previously manufactured clinical trial material for supply through 2019, partially offset by higher clinical trial activity.
General and administrative (G&A) expenses in the third quarter of 2018 were $2.4 million, as compared to $2.2 million in the same quarter last year. This increase was due primarily to higher professional fees.
Operating expenses were $3.0 million in the third quarter of 2018. Excluding a $2.7 million one-time litigation settlement gain, operating expenses were $5.7 million in the third quarter of 2018, as compared to $8.5 million in the same quarter the prior year. This decrease is primarily due to lower R&D expenses.
Total other expense for the third quarter of 2018 was $0.6 million, as compared to $1.8 million in the same quarter the prior year. This change was primarily attributed to a $0.7 million loss in fair value of the stock option liabilities in the third quarter of 2018, compared to a $1.7 million loss in the third quarter of 2017.
Net loss for the third quarter of 2018 was $3.6 million, compared to a net loss of $10.4 million for the same period in 2017. This year over year decrease in net loss was due primarily to the aforementioned $2.7 million litigation settlement gain, lower R&D expenses and change in fair value of the stock option and warrant liabilities, which were lower in the third quarter of 2018 compared to the prior year period.
As of September 30, 2018, the Company had cash of $10.1 million, as compared to cash of $28.1 million as of December 31, 2017.
In addition, on September 26, 2018, the Company entered into a securities purchase agreement (the "Purchase Agreement") with Aspire Capital Fund, LLC ("Aspire Capital"), which provides that, upon the terms, Aspire Capital is committed to purchase up to an aggregate of $20.0 million of the Company’s ADSs over the 30-month term of the Purchase Agreement. In consideration for entering into the Purchase Agreement, concurrently with the execution of the Purchase Agreement, the Company issued 30,000,000 ordinary shares to Aspire Capital and sold to Aspire Capital 25,000,000 ordinary shares for $0.02 per share (equivalent to $2.00 per ADS and $500,000).

Topo I inhibitors augment T-cell mediated antitumor immune response and enhance the efficacy of immunotherapy.

On November 15, 2018 Neovia Oncology reported that Substantial limitations in the response rates for cancer immunotherapy and increasing drug-resistance in cancer patients in general have led to a search for rational drug combination therapy (Press release, Neovia Oncology, NOV 15, 2018, View Source [SID1234531343]). It has been reported that Topoismerase types I (Topo I) and II (Topo II), already well recognized as important targets for inhibiting cellular DNA replication, are highly expressed in many cancers and also ‘cross-talk’ with Epidermal Growth Factor Receptor, which is the target of several recently approved cancer drugs. Moreover Topo I inhibitors have recently been shown to augment T-cell mediated antitumor immune response and enhance the efficacy of immunotherapy. Currently approved Topo inhibitor drugs, however, are single agents and known to be highly toxic even at low doses.

Neovia’s NEV-801 investigational product is the result of structure-based drug design to create a covalently conjugating camptothecin and podophyllotoxin derivative multi-inhibitor (simultaneously inhibiting topo I and II) with potent anti-cancer efficacy through a synergistic immune response but with minimal toxicity. For example, when used as a single agent in preclinical studies of Chronic Myelogenous Leukemia models, NEV-801 causes tumor sizes to diminish, with 38% of tumors disappearing completely and a 98% tumor growth inhibition rate compared to 0% and 33%, respectively, for leading marketed drug Imatinib (Gleevec). Weight loss was effectively overcome within a week of continued administration. Additionally in an ovarian cancer model NEV-801 was shown to be synergistic with immune checkpoint inhibitors PD-1 and CTLA-4.

Neovia is currently studying NEV-801 in a Phase 1 dose-escalation, dose-confirmation trial, in which anti-tumor effects are also being evaluated to determine the tumor types to be targeted in Phase 2. Through cohort 3 (80 mg), NEV-801 has been well tolerated with no reported serious adverse events. Importantly, NEV-801 can also be used as an oral anticancer drug, which is strongly recommended for cancer therapy of patients, since PK data analysis demonstrates that it can pass the Caco-2 cell membrane with a high permeability of 9.2. This also explains the lower GI-related toxicity.

Neovia has a strong patent portfolio with protection into 2035, with plans to file for Orphan Drug designation that will extend exclusivity for 7 years in the US and 10 years in Europe after approvals.

Anixa Biosciences To Present Cchek™ Breast Cancer Data at AACR Special Conference on Tumor Immunology and Immunotherapy

On November 15, 2018 Anixa Biosciences, Inc. (NASDAQ: ANIX), a biotechnology company focused on using the body’s immune system to fight cancer, reported that it will present data from its ongoing studies in breast cancer utilizing Cchek, Anixa’s artificial intelligence (AI) driven early cancer detection technology, at the AACR (Free AACR Whitepaper) Special Conference on Tumor Immunology and Immunotherapy (Press release, Anixa Biosciences, NOV 15, 2018, View Source [SID1234531342]). The conference is designed to integrate multidisciplinary facets of basic cancer immunology and immunotherapy to broaden the understanding of ways to harness the immune system to treat cancer. The conference will be held November 27–30, 2018 in Miami Beach, Florida and will be attended by world-renowned oncologists and scientists who will offer new insights on systems biology, checkpoints, combination therapies, and molecular targets, all in the pursuit of finding new ways to manipulate the tumor immune microenvironment and creating better treatments. To receive a copy of the presentation, please email your request to AACR (Free AACR Whitepaper)[email protected] starting November 30, 2018 and include your name, title, and contact information.

"We are pleased to make our presentation titled, Combining the immunophenotyping of MDSCs and lymphocytes with artificial intelligence (AI) to predict early stage breast cancer, at the AACR (Free AACR Whitepaper) Tumor Immunology and Immunotherapy conference. This data is focused on using our Cchek technology to detect breast cancer in its early stages. The majority of screening technologies currently used for breast cancer detection, such as mammography, have the ability to detect later stage breast malignancies rather successfully but have shown difficulty with earlier stages," stated Dr. Amit Kumar, President and CEO of Anixa Biosciences. "As we have previously announced, our initial commercial focus is on a prostate cancer test for which we will be meeting with the USFDA on December 17, 2018. We recently presented our latest prostate cancer data at the 33rd Annual Meeting of The Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper), and we look forward to now present our latest breast cancer data at this AACR (Free AACR Whitepaper) special conference," added Dr. Kumar.
