On May 6, 2016 Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, "Eisai") that its European regional headquarters Eisai Europe Ltd. (Location: U.K.) has received from the European Commission approval for anticancer agent Halaven (eribulin mesylate) for the treatment of adult patients with unresectable liposarcomas who have received prior anthracycline containing therapy (unless unsuitable) for advanced or metastatic disease (Press release, Eisai, MAY 6, 2016, View Source [SID:1234511992]). Halaven is the first and only single agent to demonstrate a statistically significant overall survival (OS) benefit in a Phase III trial in patients with advanced, recurrent or metastatic soft tissue sarcoma (liposarcoma or leiomyosarcoma). Following approval for use in the treatment of metastatic breast cancer, this marks the second indication for which Halaven has received approval based on an extension of OS.

The approval was based on the results of a Phase III study (Study 309)1 comparing the efficacy and safety of Halaven versus dacarbazine in 452 patients (aged 18 or over) with locally advanced, recurrent or metastatic soft tissue sarcoma (liposarcoma or leiomyosarcoma) who had disease progression following standard therapies which must have included an anthracycline and at least one other additional regimen. Halaven demonstrated a statistically significant extension in the study’s primary endpoint of OS over the comparator treatment dacarbazine (Halaven median OS: 13.5 months vs dacarbazine median OS: 11.5 months; Hazard Ratio (HR) 0.77 [95% CI=0.62-0.95], p=0.0169). For patients with liposarcoma, Halaven demonstrated a significant improvement in OS over dacarbazine (Halaven, median OS: 15.6 months vs dacarbazine, median OS: 8.4 months; HR 0.51 [95% CI=0.35-0.75]).
In this study, the most common treatment-emergent adverse events (incidence greater than or equal to 25%) in patients treated with Halaven were fatigue, neutropenia, nausea, alopecia, constipation, peripheral neuropathy, abdominal pain, and pyrexia, which was consistent with the known side-effect profile of Halaven.

Halaven is a halichondrin class microtubule dynamics inhibitor with a distinct binding profile. Recent non-clinical studies showed that Halaven is associated with increased vascular perfusion and permeability in tumor cores.2 Halaven promotes the epithelial state and decreases the capacity of breast cancer cells to migrate. 3 Halaven is currently approved for use in the treatment of breast cancer in approximately 60 countries including Japan and countries in Europe, the Americas and Asia. Halaven was approved in the United States for the treatment of patients with unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen in January 2016, and was approved in Japan for the treatment of soft tissue sarcoma in February 2016.
Soft tissue sarcoma is a collective term for a diverse group of malignant tumors that occur throughout the soft tissue (fat, muscle, nerves, fibrous tissues and blood vessels). Approximately 29,000 patients in Europe are diagnosed with soft tissue sarcoma each year or about 1% of all cancers diagnosed in Europe. Liposarcoma is one of the most common forms of soft tissue sarcoma. As outcomes are poor for patients with advanced disease, it remains a disease with significant unmet medical need. Eisai Co., Ltd. No.16-29 May 6, 2016 Eisai remains committed to providing additional clinical evidence for Halaven aimed at maximizing value of the drug as it seeks to contribute further to addressing the diverse needs of, and increasing the benefits provided to, patients with cancer, their families, and healthcare providers.

About Halaven
Halaven is the first in the halichondrin class of microtubule dynamics inhibitors with a novel mechanism of action. Structurally Halaven is a simplified and synthetically produced version of halichondrin B, a natural product isolated from the marine sponge Halichondria okadai. Halaven is believed to work by inhibiting the growth phase of microtubule dynamics which prevents cell division. In addition, recent non-clinical studies showed that Halaven is associated with increased vascular perfusion and permeability in tumor cores.2 Halaven promotes the epithelial state and decreases the capacity of breast cancer cells to migrate.3

Halaven was first approved in November 2010 in the United States as a treatment for patients with metastatic breast cancer who have received at least two chemotherapeutic regimens for the treatment of metastatic disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting. Halaven is currently approved for use in the treatment of breast cancer in approximately 60 countries worldwide, including Japan and countries in Europe, the Americas and Asia. In Japan, Halaven has been approved to treat inoperable or recurrent breast cancer and was launched in the country in July 2011. In addition, Halaven has been approved in countries in Europe and Asia indicated as a treatment for patients with locally advanced or metastatic breast cancer who have progressed after at least one chemotherapeutic regimen for advanced disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting, unless patients were not suitable for these treatments.

Regarding soft tissue sarcoma, Halaven was approved in the United States for the treatment of patients with unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen in January 2016, approved in Japan for the treatment of soft tissue sarcoma in February 2016, and approved in Europe for the treatment of adult patients with unresectable liposarcomas who have received prior anthracycline containing therapy (unless unsuitable) for advanced or metastatic disease in May 2016. Applications seeking approval for use in the treatment of soft tissue sarcoma are currently under review in Switzerland, Russia, Australia, Brazil, and Malaysia. Furthermore, Halaven has been designated as an orphan drug for soft-tissue sarcoma in the United States and Japan.

2. About Study 3091
Conducted primarily in Europe and the United States, Study 309 was a multicenter, open-label, randomized Phase III study comparing the efficacy and safety of Halaven versus dacarbazine in 452 patients (aged 18 or over) with locally advanced, recurrent or metastatic soft tissue sarcoma (liposarcoma or leiomyosarcoma) who had disease progression following standard therapies which must have included an anthracycline and at least one other additional regimen. Patients received either Halaven (1.4 mg/m2 administered intravenously on Day 1 and Day 8) or dacarbazine (850–1200 mg/m2 administered intravenously on Day 1) every 21 days until disease progression.

From the results for the study, Halaven demonstrated a statistically significant extension in the study’s primary endpoint of overall survival (OS) over the comparator treatment dacarbazine (Halaven median OS: 13.5 months vs dacarbazine median OS: 11.5 months; Hazard Ratio (HR) 0.77 [95% CI=0.62-0.95], p=0.0169). Furthermore, in the study’s secondary endpoints, there was no statistically significant difference found between Halaven and dacarbazine in either progression-free survival (PFS) (median PFS: 2.6 months in both arms) or progression-free rate at 12 weeks (PFR12wks) (Halaven PFR12wks: 33% vs dacarbazine PFR12wks: 29%).

For patients with liposarcoma (143 patients), Halaven demonstrated a statistically significant improvement in OS over dacarbazine (Halaven, median OS: 15.6 months vs dacarbazine, median OS: 8.4 months; HR 0.51 [95% CI=0.35-0.75]).

In this study, the most common treatment-emergent adverse events (incidence greater than or equal to 25%) in patients treated with Halaven were fatigue, neutropenia, nausea, alopecia, constipation, peripheral neuropathy, abdominal pain, and pyrexia, which was consistent with the known side-effect profile of Halaven.

3. About Soft Tissue Sarcoma
Soft tissue sarcoma is a collective term for a diverse group of malignant tumors that occur throughout the soft tissue (including fat, muscle, nerves, fibrous tissues and blood vessels). Approximately 12,000 patients in the United States and 29,000 patients in Europe are diagnosed with soft tissue sarcoma each year. According to a patient survey conducted by Japan’s Ministry of Health, Labour and Welfare, there are approximately 4,000 patients with soft tissue sarcoma in Japan. As the structures where the tumors originate are diverse, there are various types of soft tissue sarcoma, and the most common types include leiomyosarcoma, liposarcoma and malignant fibrous histiocytoma. While treatment of soft tissue sarcoma is focused on curative surgery, if the stage of the disease is advanced, treatment then becomes a combination of chemotherapy and radiation therapy. As outcomes are poor for patients with advanced disease, it remains a disease with significant unmet medical need.

On May 06, 2016 CytomX Therapeutics, Inc. (Nasdaq:CTMX), a biopharmaceutical company developing investigational Probody therapeutics for the treatment of cancer, reported financial results for the first quarter ending March 31, 2016 (Press release, CytomX Therapeutics, MAY 6, 2016, View Source;p=RssLanding&cat=news&id=2165975 [SID:1234511991]).

"Since our IPO, we have maintained strong strategic and operational momentum as demonstrated by our partnership with AbbVie and the advancement of our wholly-owned programs towards the clinic," said Sean McCarthy, D.Phil., president and chief executive officer of CytomX Therapeutics. "With this progress and our strong cash position we are well-positioned to build a multi-product company to transform antibody therapeutics for the treatment of cancer."

As of March 31, 2016, CytomX had cash and cash equivalents and short-term investments of $180.6 million. The Company has updated its financial guidance and expects net cash utilization of $20.0 to $25.0 million in 2016, reduced from its previous guidance of $45.0 to $50.0 million. The Company is maintaining its guidance that its existing capital resources will be sufficient to fund its anticipated operations through 2018.

Business Highlights and Recent Developments

On April 21, 2016, the Company announced that it had entered into a collaboration with AbbVie to co-develop and co-commercialize Probody Drug Conjugates against CD71, with CytomX leading pre-clinical and early clinical development. AbbVie will lead later development and commercialization, with global late-stage development costs shared between the two companies. CytomX received an upfront payment of $30 million and is eligible to receive up to $470 million in development, regulatory and commercial milestones, pending the achievement of pre-determined outcomes. AbbVie will lead global commercial activities with CytomX eligible to receive a profit share in the U.S. and tiered double-digit royalties on net product sales outside of the U.S. CytomX retains an option to co-promote in the U.S.

On April 19, 2016, the Company presented data from its PD-1 and CD71 programs at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting evidencing efficacy and improved tolerability for Probody therapeutics in preclinical models.

The Company remains on track to file an IND for CX-072, a Probody therapeutic targeting PD-L1, in the second half of 2016 and an IND for CX-2009, a Probody drug conjugate targeting CD166, in the first half of 2017.

During the first quarter, the Company announced selection of a third target by Bristol-Myers Squibb in accordance with the companies’ strategic oncology collaboration established in May 2014, triggering a $10 million milestone payment.

First Quarter Financial Results

Cash, cash equivalents and investments totaled $180.6 million as of March 31, 2016, compared to $186.7 million as of December 31, 2015. The decrease reflects cash used in operations offset by a $10.0 million milestone payment received from Bristol-Myers Squibb in connection with their third target selection in January 2016.

Research and development expenses were $13.4 million for the first quarter of 2016, compared to $4.7 million for the first quarter of 2015. The increase was primarily attributable to $4.9 million in manufacturing costs for the Company’s CX-072 and CX-2009 programs in preparation for preclinical and clinical studies, $1.3 million in laboratory and professional services, $1.3 million in non-cash stock based compensation due to higher stock valuation, $0.8 million in personnel-related expenses due to an increase in headcount and $0.4 million in royalty payments to a third party triggered by Bristol-Myers Squibb’s milestone payment in connection with its third target selection. The Company expects the manufacturing costs for the two programs to continue into the second quarter and the costs related to preparation for CX-072 clinical trials to increase in the third quarter.

General and administrative expenses were $5.0 million for the first quarter of 2016, compared to $1.9 million for the first quarter of 2015. The increase was primarily attributable to $1.2 million in additional consulting and professional service expenses associated with operating as a public company, $1.1 million in non-cash stock based compensation due to higher stock valuation and $0.7 million in personnel-related expenses due to an increase in headcount.

On May 5, 2016 Novocure (NASDAQ: NVCR) reported the availability of a new online resource to raise awareness of glioblastoma (GBM) and share stories of inspiration with the GBM community (Press release, NovoCure, MAY 5, 2016, View Source [SID:1234512063]). An interactive exhibit featuring patients, caregivers, doctors, nurses and advocates will also be displayed within the coming months.

Approximately 12,500 GBM tumors, or tumors that may transform to GBM, are diagnosed in the U.S. each year. GBM can spread quickly and is one of the deadliest forms of cancer.

The website, GBMcommunity.com, features a mosaic of videos and images from the GBM community offering messages of hope and inspiration. The website also provides an overview of GBM and links to resources and advocacy groups.

"Novocure actively engaged members of the community to determine the resources they felt they needed most," said Pritesh Shah, Senior Vice President, Americas. "This new website and exhibit were born from the GBM community, and created with assets provided by the community. No one can speak to the experiences, hopes and needs of those affected by GBM better than they can. We are proud to bring this important resource to the GBM community, and thank all who have provided their words of support and images to this project, and encourage others to do the same. Only by making our collective voices heard can we raise awareness of this disease and deliver increased support."
About Glioblastoma Multiforme

Glioblastoma, also called glioblastoma multiforme, or GBM, is a type of primary brain cancer. This means that GBM tumors begin in the brain, rather than traveling to the brain from other parts of the body, such as the lungs or breasts. GBM is the most common type of primary brain cancer in adults. It is more likely to appear in adults than children and to affect men than women.
