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 5, 2016 Mustang Bio, Inc. ("Mustang"), a Fortress Biotech (NASDAQ: FBIO) Company, reported that an oral presentation related to its MB-101 (IL13Rα2-specific CAR T cells) product candidate in development was presented by City of Hope ("COH") Investigators at the American Society of Gene and Cell Therapy 19th Annual Meeting (ASGCT) (Free ASGCT Whitepaper) at the Marriott Wardman Park Hotel in Washington, DC (Filing, 8-K, Fortress Biotech, 2016, MAY 6, 2016, View Source [SID:1234512023]).

Michael S. Weiss, Mustang Bio’s Executive Chairman, Interim Chief Executive Officer and President commented on the data, "We are very encouraged by the early safety and efficacy profile demonstrated by MB-101 (IL13Rα2-specific CAR T cells) to date. We were particularly impressed with the data presented today showing a patient treated at the first dose level who obtained an investigator designated complete response to MB-101. We believe this is the first demonstration of a response in a GBM patient utilizing CAR-T treatment. We are eager to continue the dose escalation to further assess the safety, activity and durability of MB-101 treatment at higher doses." Mr. Weiss continued, "We would like to thank the investigators at City of Hope for all of their efforts on this important research program."

The following summarizes the oral presentation today:

Phase I Study of Second Generation Chimeric Antigen Receptor–Engineered T cells Targeting IL13Rα2 for the Treatment of Glioblastoma

The Phase I study abstract that was presented showed early data evaluating the safety, feasibility and bioactivity of weekly intracranial infusions of autologous IL13Rα2-specific CAR T cells in patients with recurrent IL13Rα2+ GBM. On this study, patients are treated on a 4-week therapeutic regimen consisting of 3 weekly intracranial infusions of IL13Rα2-specific CAR T cells followed by one rest week for toxicity and disease assessment. To date, treatment of the first low dose cohort of patients has been completed demonstrating that local delivery of IL13Rα2-specific CAR T cells post-surgical resection appeared to be safe and well-tolerated, with no grade 3 or higher toxicities attributed to the therapy reported. Importantly, early evidence for antitumor activity following CAR T cell administration was observed.

One patient of particular interest presented with a recurrent multifocal GBM, including one metastatic site in the spine and extensive leptomeningeal disease. This patient was initially treated per protocol with six local infusions of IL13Rα2-specific CAR T cells into the resection cavity of the largest recurrent tumor focus in the posterior temporal-occipital region. Encouragingly, this CAR T cell injection site remained stable without evidence of disease recurrence for over 7-weeks, while other disease foci distant from the CAR T cell injection site continued to progress. This patient was then treated on a compassionate use protocol with five weekly intraventricular infusions of IL13Rα2-specific CAR T cells without any other therapeutic interventions. The investigator reported today that following treatment the patient achieved a complete response. Early clinical findings suggest that intracranial delivery of second-generation IL13Rα2-targeted CAR T cells is safe and well-tolerated, and that after adoptive transfer, CAR T cells survive and maintain activity, capable of eliciting potent antitumor responses against recurrent multifocal glioblastoma.

About Glioblastoma multiforme (GBM)
Glioblastomas (GBM) are tumors that arise from astrocytes cells that make up the supportive tissue of the brain. These tumors are usually highly malignant (cancerous) because the cells reproduce quickly and they are supported by a large network of blood vessels. GBM is the most common brain and central nervous system (CNS) malignancy, accounting for 15.1% of all primary brain tumors, and 55.1% of all gliomas. There are an estimated 12,120 new glioblastoma cases predicted in 2016 in the U.S. Malignant brain tumors are the most common cause of cancer-related deaths in adolescents and young adults aged 15-39 and the most common cancer occurring among 15-19 year olds in the U.S. (Brain Tumor Statistics. American Brain Tumor Association. December 2015). While GBM is a rare disease (2-3 cases per 100,000 person life years in the U.S. and E.U.), it is quite lethal with 5-year survival rates historically less than 10%. Chemotherapy with temozolomide and radiation are shown to extend mean survival from ~12 to ~15 months, while surgery remains the standard of care. GBM remains difficult to treat due to the inherent resistance of the tumor to conventional therapies. Treatment is further complicated by the susceptibility of the brain to damage, difficulty of the brain to repair itself and limitation to drugs crossing the blood brain barrier. Immunotherapy approaches targeting brain tumors offer promise over conventional treatments.

About MB-101 (IL13Rα2-specific CAR-T cells)
IL13Rα2 is an attractive target for CAR-T therapy as it has limited expression in normal tissue but is over-expressed on the surface of the majority of GBM. CAR T cells designed to express a membrane-tethered IL-13 receptor ligand (IL-13) incorporating a single point mutation that provides high affinity for IL13Rα2 and reduces binding to IL13Rα1 in order to reduce healthy tissue targeting.

We are developing an optimized CAR-T product incorporating enhancements in CAR design and T cell engineering to improve antitumor potency and T cell persistence. We include a second generation hinge optimized CAR containing mutations in the IgG4 linker to reduce off-target Fc interactions, as well as the 41BB (CD137) co-stimulatory signaling domain for improved persistence of CAR T cells, and extracellular domain of CD19 as a selection/safety marker. In order to further improve persistence, central memory T cells are enriched and genetically engineered using a manufacturing process that limits ex vivo expansion in order to reduce T cell exhaustion and maintain a memory T cell phenotype.

"Our positive GEN-003 Phase 2 12-month efficacy data suggests that annual treatment with GEN-003 may offer genital herpes patients similar benefits to a full year of daily administration of oral antivirals. These data give us confidence in the potential of GEN-003 to become the cornerstone therapy for patients suffering from genital herpes," said Chip Clark, president and chief executive officer of Genocea. "For our recently initiated Phase 2b efficacy trial, we anticipate reporting virologic efficacy data in the third quarter of 2016, which we anticipate will confirm the efficacy of GEN-003 manufactured using improved processes at an increased scale. We expect clinical efficacy data versus placebo against potential Phase 3 endpoints at six months post dosing around the end of 2016 and we expect to conduct our end-of-Phase 2 meeting with the FDA in the first quarter of 2017. We also continue to advance our academic collaborations in the immuno-oncology field and expect to provide further updates in the coming months on our potential path to the clinic in 2017 for a neoantigen-based cancer vaccine."

Recent Business Highlights and Anticipated Milestones

GEN-003 – Immunotherapy for treatment of genital herpes in Phase 2 development. Greater than $1 billion potential revenue opportunity in U.S. alone

• Reported positive 12-month efficacy data from Phase 2 dose optimization trial
• Full data to be presented at an upcoming scientific meeting

In March 2016, Genocea announced positive 12-month efficacy data from its Phase 2 dose optimization trial evaluating GEN-003 for the treatment of genital herpes. GEN-003 demonstrated statistically significant reductions compared to baseline in the rate of viral shedding 12 months after dosing as well as sustained efficacy across secondary clinical endpoints, in each case across multiple dose groups. GEN-003 was safe and well tolerated by patients, with no serious adverse events reported related to the vaccine in the trial.

Multiple anticipated 2016 clinical milestones for GEN-003

• Phase 2b virologic efficacy data expected in third quarter of 2016
• Phase 2b 6-month clinical efficacy data expected in late 2016
• End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) expected in Q1 2017

In the third quarter of 2016, Genocea expects to report virologic efficacy data from a Phase 2b trial to confirm the efficacy of GEN-003 manufactured with Phase 3 processes at increased scale. Around the end of 2016, Genocea expects to report 6-month clinical efficacy versus placebo against the potential Phase 3 endpoint of the percentage of patients that are lesion free at 6-months after dosing. Positive data would provide an important step toward the end-of-Phase 2 meeting with the FDA, which is expected to occur in the first quarter of 2017.

This ongoing trial has enrolled approximately 135 subjects across the U.S. who have a history of recurrent genital herpes. Subjects will be randomized to one of three dose groups – placebo, 60µg per protein / 50µg of adjuvant, and 60µg per protein / 75µg of adjuvant – and will be monitored for 12 months.

Genocea also expects to commence a planned Phase 2b antiviral combination study in the second half of 2016. Clinical efficacy data from this trial is expected in the first half of 2017. If GEN-003 is additive to the effect of chronic suppressive oral anti-viral therapy, this would further strengthen GEN-003’s value proposition to patients and physicians.

First Quarter 2016 Financial Results

Cash Position: Cash, cash equivalents and investments as of March 31, 2016 were $95.7 million compared to $106.4 million as of December 31, 2015. Genocea expects that these funds will be sufficient to fund its operating expenses and capital expenditure requirements into the second half of 2017.
Research and Development (R&D) Expenses: R&D expenses for the quarter ended March 31, 2016 decreased $1.2 million, to $7.3 million, from the same period in 2015. The decrease was driven by lower clinical costs due to the completion of the GEN-004 Phase 2a trial, which was ongoing in the first quarter of 2015, and the conduct of a smaller Phase 2 trial for GEN-003 in the first quarter of 2016 compared to the same period in 2015. GEN-003 manufacturing costs also decreased due to the timing of activities in support of clinical trial supply. These lower costs were partially offset by higher personnel and lab-related costs to advance Genocea’s pre-clinical product candidates and develop the ATLAS platform for immuno-oncology.
General and Administrative (G&A) Expenses: G&A expenses for the first quarter of 2016 were $3.9 million, compared to $3.4 million for the same period in 2015. The increase reflects higher personnel costs, consulting and professional fees, and depreciation expense, all of which support Genocea’s expanding R&D operations.
Refund of Research and Development Expense: A gain of $1.6 million for the quarter ended March 31, 2016 resulted from cash received pursuant to contractual obligations under a collaboration agreement with Isconova AB ("Isconova") (since acquired by Novavax, Inc.) to refund R&D expenses paid by Genocea to Isconova between 2009 and 2011 relating to the development of the Matrix-M2TM adjuvant technology.
Net Loss: Net loss was $9.8 million for the quarter ended March 31, 2016, compared to a net loss of $12.1 million for the same period in 2015.

On May 5, 2016 Neurocrine Biosciences, Inc. (NASDAQ:NBIX) reported its financial results for the quarter ended March 31, 2016 (Press release, Neurocrine Biosciences, MAY 5, 2016, View Source;p=RssLanding&cat=news&id=2165670 [SID:1234512030]). For the first quarter of 2016, the Company reported a net loss of $19.3 million, or $0.22 loss per share, compared to a net loss of $1.2 million, or $0.01 loss per share, for the same period in 2015.

The Company’s balance sheet at March 31, 2016 reflected cash, cash equivalents, investments and receivables of $448.6 million compared to $464.3 million at December 31, 2015.

"2015 was a very successful year for Neurocrine and we have carried this momentum into the first quarter of 2016 beginning with positive top-line data from the second Phase III study of elagolix in endometriosis, the initiation of two Phase III studies of elagolix in uterine fibroids, the start of our Phase II T-Force GREEN study of valbenazine in children and adolescents with Tourette syndrome, as well as the acceptance of seven valbenazine abstracts at the American Academy of Neurology and American Psychiatric Association Annual Meetings" said Kevin Gorman, Ph.D., President and Chief Executive Officer of Neurocrine Biosciences. "Our focus for the coming months is to continue to execute across all aspects of our business; advancing compounds from research into the clinic, executing on clinical trials, filing the valbenazine NDA, and interacting with providers and payers as we prepare for the commercial launch of valbenazine for tardive dyskinesia upon FDA approval."

The $15.0 million of revenue for the first quarter of 2016 represents a milestone payment from AbbVie related to the commencement of Phase III studies of elagolix in uterine fibroids. The $19.8 million of revenue for the first quarter of 2015 represents recognized revenue in the form of license fees from the NBI-98854 (valbenazine) collaboration and license agreement with Mitsubishi Tanabe.

Research and development expenses increased to $23.9 million during the first quarter of 2016 from $16.6 million during the same period in 2015. This increase was primarily due to higher external clinical development expenses and associated internal costs related to the Company’s VMAT2 inhibitor, valbenazine, which is being evaluated in both tardive dyskinesia and Tourette syndrome. Additionally, expenses related to the Company’s preparation of the New Drug Application for valbenazine in tardive dyskinesia accounted for a portion of the increase in expenses quarter over quarter.

General and administrative expenses increased from $5.5 million in the first quarter of 2015 to $12.0 million for the first quarter of 2016, primarily due to pre-commercialization activities for valbenazine. Personnel related costs increased by $3.9 million quarter over quarter primarily due to the expansion of sales and marketing and medical affairs personnel. This increase in personnel related costs includes a $2.4 million increase in share-based compensation expense. Additionally, a significant increase in other pre-commercialization activities contributed to the overall growth in general and administrative expenses.

Pipeline Highlights

Valbenazine Update

During the fourth quarter of 2015, the Company announced positive efficacy results from the Kinect 3 study, a Phase III trial that included moderate to severe tardive dyskinesia in patients with underlying schizophrenia, schizoaffective disorder, bipolar or major depressive disorder who underwent six weeks of placebo controlled assessment. Subsequent to the initial six weeks of treatment, subjects were eligible to continue in the Kinect 3 study for an additional 42 week open-label safety assessment. The open-label safety evaluation is anticipated to complete dosing in mid-2016.

In addition to the ongoing safety assessment of Kinect 3, during the first quarter of 2016 the Company completed enrollment in a separate one-year open-label safety study of valbenazine, Kinect 4, to support the anticipated 2016 filing of a New Drug Application of valbenazine in tardive dyskinesia.

The Company also recently initiated a valbenazine roll-over study for those patients who complete the one year of dosing in either the Kinect 3 or Kinect 4 studies. This roll-over study is designed to permit open-label access to valbenazine for up to an additional 72 weeks of treatment.

As announced previously, Neurocrine has received Breakthrough Therapy Designation from the FDA for valbenazine in the treatment of tardive dyskinesia.

The Company is also exploring valbenazine in Tourette syndrome. The Company recently announced the initiation of two Phase II Tourette syndrome studies evaluating valbenazine in adults and pediatrics, the T-Forward study and T-Force GREEN study, respectively.

The T-Forward study is a randomized, double-blind, placebo-controlled, multi-dose, parallel group, study of up to 90 adults. Subjects will receive once-daily dosing of valbenazine during an eight-week treatment period to assess the safety, tolerability and efficacy of valbenazine in adult Tourette patients. The primary endpoint of this study is a change from baseline of placebo vs. active scores utilizing the Yale Global Tic Severity Scale at the end of Week 8.

The T-Force GREEN study is a randomized, double-blind, placebo-controlled, multi-dose, parallel group study of up to 90 children and adolescents. Subjects will receive once-daily dosing of valbenazine during a six-week treatment period to assess the safety, tolerability and efficacy of valbenazine in pediatric Tourette patients. The primary endpoint of this study is the change from baseline of the Yale Global Tic Severity Scale between placebo and active treatment groups at the end of Week 6.

Data from both of these Tourette studies is expected around year-end 2016.

The Company has submitted and had accepted seven valbenazine abstracts at two major medical conferences during the second quarter. Valbenazine data from all three Kinect clinical trials were presented at podium and plenary sessions at the American Academy of Neurology Annual Meeting in April. In addition, four valbenazine scientific abstracts were submitted and accepted for the American Psychiatric Association Annual Meeting in May.

Elagolix Update

During the first quarter of 2016, AbbVie announced positive top-line results from the second of two Phase III clinical trials, the Solstice Study, a multinational study designed to evaluate the efficacy and safety of elagolix in 815 premenopausal women with endometriosis. The top-line results from this trial were consistent with those of the initial Phase III clinical trial, the Violet Petal Study, where after six months of treatment, both doses of elagolix (150 mg once-daily and 200 mg twice-daily) met the study’s co-primary endpoints of reducing scores of non-menstrual pelvic pain and menstrual pain (or dysmenorrhea) associated with endometriosis at month three, as well as month six, as measured by the Daily Assessment of Endometriosis Pain scale. The observed safety profile of elagolix in the Solstice study was consistent with observations from prior studies. Among the most common adverse events (AEs) were hot flush, headache, and nausea. While most AEs were similar across treatment groups some, such as hot flush and bone mineral density loss, were dose-dependent. AbbVie is targeting a 2017 New Drug Application filing with the FDA for elagolix in endometriosis.

In early 2016, AbbVie announced the initiation of the Phase III uterine fibroids program consisting of two replicate randomized, parallel, double-blind, placebo-controlled clinical trials evaluating elagolix alone or in combination with add-back therapy in women with heavy uterine bleeding associated with uterine fibroids. The studies are expected to enroll approximately 400 subjects each for an initial six-month placebo-controlled dosing period. At the end of the six-months of placebo-controlled evaluation, subjects are eligible to enter an additional six-month safety extension study. The primary efficacy endpoint of the study is an assessment of the change in menstrual blood loss utilizing the alkaline hematin method comparing baseline to month six. Additional secondary efficacy endpoints will be evaluated including assessing the change in fibroid volume and hemoglobin. Bone mineral density will be assessed via DXA scan at baseline, the conclusion of dosing, and six months post-dosing.

Essential Tremor Program (NBI-640756) Update

NBI-640756 for patients with essential tremor was discovered in the Neurocrine laboratories. The Company has completed dosing in a single site, randomized, double-blind, placebo-controlled, sequential dose-escalation, pharmacokinetic study assessing the safety and tolerability of a single dose of NBI-640756 in up to 32 healthy volunteers. The study was conducted in multiple sequential cohorts of eight subjects per cohort. Data from this initial Phase I study is expected in the second quarter of 2016.

On May 5, 2016 Akebia Therapeutics, Inc. (NASDAQ:AKBA), a biopharmaceutical company focused on delivering innovative therapies to patients through the biology of hypoxia-inducible factor (HIF), reported financial results for the first quarter ended March 31, 2016 (Press release, Akebia , MAY 5, 2016, View Source [SID:1234512062]). Akebia also provided an update on its Phase 3 INNO2VATE program for vadadustat in dialysis-dependent chronic kidney disease (DD-CKD), and reported data from an ethnobridging study for vadadustat.

"We continue to execute our strategy designed to position vadadustat as a best-in-class treatment for renal anemia, define a clear path to registration and establish strong commercial support in key markets," said John P. Butler, President and Chief Executive Officer of Akebia. "With the recent European Patent Office decision, we have preserved our access to an important region and are well-positioned to pursue a European collaboration that would provide funding for the balance of our Phase 3 program."

Mr. Butler continued, "On the clinical front, we have now reached alignment with regulators regarding our global Phase 3 program. We are advancing our ongoing global Phase 3 PRO2TECT program in non-dialysis dependent patients (NDD-CKD), and look forward to initiating the INNO2VATE program in DD-CKD patients in the third quarter of 2016. We are also expanding our experience with HIF-PH inhibitors, and plan to begin a Phase 1 trial with our second clinical candidate, AKB-6899, this year."

INNO2VATE Program

Akebia announced today that it has reached alignment with both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) regarding key elements of the Phase 3 INNO2VATE program and expects to launch the program in the third quarter of 2016. The INNO2VATE program includes two separate studies and will collectively enroll approximately 2,600 DD-CKD patients globally. The correction study will enroll approximately 400 patients not currently being treated with recombinant erythropoiesis stimulating agents (rESAs). The conversion study will enroll approximately 2,200 patients currently receiving rESA who will be converted to either vadadustat or the active control with the goal of maintaining their baseline hemoglobin levels. Both studies will include a 1:1 randomization and an open label, active-control, non-inferiority design. Primary endpoints include an efficacy assessment of the hemoglobin response and an assessment of cardiovascular safety measured by major adverse cardiovascular events.

Ethnobridging Study Results

The company announced today that data from its recent ethnobridging study demonstrated that the pharmacokinetics of vadadustat in Japanese volunteers is similar to that in Caucasians at all doses studied. The double-blind study was designed to assess the pharmacokinetics and pharmacodynamics of vadadustat following the administration of multiple ascending doses (150 mg, 300 mg and 600 mg) once daily for 10 days in Japanese and Caucasian healthy volunteers. At all doses studied, the pharmacokinetics and pharmacodynamics of vadadustat in the Japanese population were similar to that observed in Caucasians.

"As we anticipated, these results demonstrate that ethnicity has no effect on the clearance of vadadustat, an important finding that further supports our global development and commercialization strategy in Japan and other Asian markets," stated Brad Maroni, Chief Medical Officer of Akebia. "Together with our partner in Asia, Mitsubishi Tanabe, we look forward to incorporating these results into our plans for vadadustat in the region."

First Quarter 2016 Corporate Highlights

Preserved access to the European market for vadadustat by prevailing in a patent dispute in which the European Patent Office confirmed that none of FibroGen, Inc.’s patent claims met the requirements for patentability and, as a result, revoked the patent in its entirety; and,
Raised approximately $61.0 million, net, in a public offering of approximately 7.3 million shares of common stock in January 2016.
Financial Results

Akebia reported a net loss of ($25.8) million, or ($0.70) per share, for the first quarter of 2016. Net loss for the first quarter of 2015 was ($10.7) million or ($0.53) per share.

Research and development expenses were $20.2 million for the first quarter of 2016 compared to $6.7 million for the first quarter of 2015. The increase is primarily attributable to costs related to the initiation of the PRO2TECT Phase 3 program. Research and development expenses were further increased by personnel-related costs due to additional headcount.

General and administrative expenses were $5.8 million for the first quarter of 2016 compared to $4.2 million for the first quarter of 2015. The increase is primarily due to the following expense increases: $0.8 million due to increased headcount and compensation related costs and $0.8 million in commercial planning costs as well as legal costs.

The Company’s cash provided by operations during the first quarter of 2016 was $17.4 million, an increase of $25.8 million from $8.3 million used in operations for the same period of 2015. The increase is primarily related to the upfront payment of $40.0 million received in January 2016 from Mitsubishi Tanabe in connection with our collaboration agreement. The Company ended the first quarter of 2016 with cash, cash equivalents and available for sale securities of $217.0 million and expects its cash resources to fund its current operating plan through at least the second quarter of 2017.
