PharmaCyte Biotech Strengthens Protection of Cancer Therapy with Patent Filing

On March 22, 2017 PharmaCyte Biotech, Inc. (OTCQB:PMCB), a clinical stage biotechnology company focused on developing targeted treatments for cancer and diabetes using its signature live-cell encapsulation technology, Cell-in-a-Box, reported that it has filed a provisional patent application with the United States Patent and Trademark Office (USPTO) to protect its therapy to treat cancerous tumors, including the therapy that will be used in its upcoming clinical trial in locally advanced pancreas cancer (LAPC) (Press release, PharmaCyte Biotech, MAR 22, 2017, View Source [SID1234518239]).

The patent application specifically includes methods of treating all cancerous tumors, such as pancreas, liver, breast and colon, using the live-cell encapsulation of genetically modified human cells that overexpress a form of the Cytochrome P450 enzyme system normally found in the liver. These cells are encapsulated using the Cell-in-a-Box technology. Together with low doses of ifosfamide, the encapsulated cells comprise PharmaCyte’s therapy for cancerous tumors. The patent application also includes using PharmaCyte’s platform technology with cyclophosphamide, another chemotherapy drug that must be activated by the Cytochrome P450 enzyme system.

"By filing for a new patent, we have begun taking steps to obtain patent protection for 20 years to protect our therapy for all forms of malignant tumors. This is particularly important to the company as we are taking steps to embark upon a clinical trial in pancreas cancer," said PharmaCyte’s Chief Executive Officer, Kenneth L. Waggoner. "We will be filing for new patent protection in all of the countries in which PharmaCyte currently has patent protection for pancreas cancer."

Provisional patent applications are a way to establish and protect a "date of invention" or "priority filing date" for one year. The provisional patent application was created to provide inventors with a way to begin protecting their inventions. A provisional patent application provides PharmaCyte 12 months to prepare a full patent application during which it can label its inventions as "patent pending." It also enables PharmaCyte to establish an early effective filing date for a patent.

The family of patents that deal with the subject matter of the new patent application are set to expire on March 27, 2017. The new patent application is designed to continue patent protection of PharmaCyte’s therapy for cancerous tumors. It is not an extension of the existing patents. A new patent for PharmaCyte’s cancer therapy, if granted by the USPTO, will provide another 20 years of patent protection from the date of the filing of this Provisional Patent Application – March 21, 2017.

PharmaCyte therapy for pancreas cancer is already protected. PharmaCyte’s pancreas cancer therapy was designated an orphan drug and listed in the official registry of medicinal products for rare diseases by the U.S. Food and Drug Administration (FDA) on December 17, 2014. This orphan drug status assures marketing exclusivity for PharmaCyte’s pancreas cancer therapy in the U.S. for 7 years after market approval by the FDA. Similarly, PharmaCyte has orphan drug status in the European Union (EU) for its pancreas cancer therapy. This designation provides 10 years of marketing exclusivity in all countries in the EU following approval by the European Medicines Agency (EMA).

In addition, the Biologics Price Competition and Innovation Act (BPCIA), which was enacted as part of the Affordable Care Act in 2010, establishes a period of 12 years of "data exclusivity" for reference products to preserve incentives for future innovation. Under this framework, data exclusivity protects the data in the innovator’s regulatory application by prohibiting others, for a period of 12 years, from gaining FDA approval based in part on reliance on or reference to the innovator’s data in a biosimilar application. PharmaCyte’s 12-year exclusivity will begin as soon as the FDA approves the company’s pancreas cancer therapy.

Mr. Waggoner concluded by stating, "While this patent application should make our investors feel assured about the protection of our pancreas cancer therapy, they should understand that if our pancreas cancer therapy receives FDA approval, the orphan drug designation in the U.S. and the EU, together with the BPCIA data exclusivity, will give us substantial marketing exclusivity for our pancreas cancer therapy. This new patent application, while it does include our pancreas cancer therapy, should really be viewed as an opportunity to dramatically broaden PharmaCyte’s ability to protect our therapy for all malignant tumors for the next 20 years."

AVEO Reports Full Year 2016 Financial Results and Provides Business Update

On March 22, 2017 AVEO Oncology (NASDAQ:AVEO) reported financial results for the full year ended December 31, 2016 and provided a business update (Press release, AVEO, MAR 22, 2017, View Source [SID1234518237]).

"TIVO-3, our lead clinical program designed to serve as the basis for a potential U.S. registration for tivozanib as a first- and third-line treatment for renal cell cancer, continues to enroll ahead of schedule and has now completed its first safety review," said Michael Bailey, president and chief executive officer of AVEO. "We look forward to the study’s pre-planned interim futility analysis midyear 2017 and, potentially, to top line results in the first quarter of 2018 and to initial data from our Phase 1 TiNivo study of tivozanib in combination with Opdivo in the first half of 2017. We also continue to support our partner EUSA Pharma in its efforts to complete the European Marketing Authorization Application review for tivozanib as a first-line treatment for renal cell carcinoma. There remains a significant unmet need for better tolerated therapies in this disease, particularly those that enable combination treatment, and we look forward to receiving tivozanib data and to potential regulatory milestones in the coming quarters."

Mr. Bailey continued: "We also look forward to several milestones with the balance of our pipeline, including the presentation of data from two investigator sponsored studies of ficlatuzumab, a potential partnership for AV-353, and progress toward the clinic for AV-380 and AV-203."

Recent Updates

TIVO-3 Enrolling Ahead of Schedule and Passes First Safety Monitoring Committee Safety Review; Pre-Planned Interim Futility Analysis Expected Midyear 2017. In February 2017, AVEO announced that its pivotal, Phase 3 TIVO-3 trial, a randomized, controlled, multi-center, open-label study to compare tivozanib to sorafenib in subjects with refractory advanced renal cell carcinoma (RCC), has successfully completed the first safety review by the study’s Safety Monitoring Committee (SMC). The SMC concluded that no safety concern was observed for tivozanib and recommended that the study replace the small number of patients who dropped out prior to starting treatment. The Company announced just prior to the safety review that the TIVO-3 trial is enrolling substantially ahead of schedule. With the SMC recommendation to replace early dropouts, the Company still expects to complete enrollment in June 2017, ahead of its prior guidance of August 2017. A pre-planned futility analysis of the trial is expected around midyear 2017, with topline data expected in the first quarter of 2018. The TIVO-3 trial, together with the previously completed TIVO-1 trial of tivozanib in the first-line treatment of RCC, is designed to support potential regulatory approval of tivozanib in the U.S. as a third- and first-line treatment for RCC.
First Patient Dosed in Phase 1/2 TiNivo Trial Evaluating Tivozanib in Combination with Bristol-Myers Squibb’s Opdivo (nivolumab) in Advanced RCC. AVEO announced today that the first patient has been treated in the Company’s Phase 1/2 TiNivo trial evaluating tivozanib in combination with Bristol-Myers Squibb’s anti-PD-1 therapy, Opdivo (nivolumab), in advanced RCC. The study, which is led by the Institut Gustave Roussy in Paris, is under the direction of Professor Bernard Escudier, MD, Chairman of the Genitourinary Oncology Committee. The Phase 1, which the Company expects to complete in the first half of 2017, will primarily evaluate the safety of tivozanib in combination with nivolumab at escalating doses of tivozanib. If the Company receives favorable results, it expects to follow immediately with an expansion Phase 2 at the established combination dose.
Ongoing Review of the Marketing Authorization Application (MAA) in Europe for Approval of Tivozanib as a First-Line RCC Treatment Option. In February 2017, AVEO announced that its European licensee for tivozanib, EUSA Pharma, a specialty pharmaceutical company with a focus on oncology and oncology supportive care, has received the Day 180 List of Outstanding Issues (LOI) from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA). The Day 180 LOI signifies that the MAA is not approvable at the present time and outlines outstanding deficiencies, which are then required to be satisfactorily addressed in an oral explanation and/or in writing prior to a final application decision. EUSA has informed AVEO that it expects to submit written responses to the Day 180 LOI in April 2017, and the EMA has tentatively scheduled EUSA to provide an oral explanation to the CHMP in May 2017.
Submitted for Presentation Results from Phase 1 Studies of Ficlatuzumab in Combination with Cetuximab in Head and Neck Squamous Cell Cancer (HNSCC) and Cytarabine in Acute Myeloid Leukemia (AML). The Company announced today that results from two investigator sponsored Phase 1 studies of ficlatuzumab were submitted for presentation at an upcoming major medical meeting. The first study is designed to explore cetuximab in combination with ascending doses of ficlatuzumab in patients with cetuximab-refractory HNSCC patients. The second study is designed to explore cytarabine in combination with ascending doses of ficlatuzumab in relapsed/refractory AML. AVEO and Biodesix, Inc. have a worldwide agreement to develop and commercialize ficlatuzumab.
Full Year 2016 Financial Highlights

AVEO ended 2016 with $23.3 million in cash, cash equivalents and marketable securities as compared with $34.1 million at December 31, 2015.
Total collaboration revenue for 2016 was approximately $2.5 million compared with $19.0 million for 2015.

Financial Guidance

We believe that our $23.3 million in existing cash, cash equivalents and marketable securities as of December 31, 2016 could allow us to fund our planned operations into the fourth quarter of 2017; however, additional funds will be needed to extend these operations into 2018 and maintain compliance with our $10.0 million financial covenant under our loan agreement with Hercules.

Sunesis Pharmaceuticals Announces Submission of Responses to the EMA Day 180 List of Outstanding Issues for Marketing Authorization Application for Vosaroxin

On March 22, 2017 Sunesis Pharmaceuticals, Inc. (Nasdaq:SNSS) reported that it has submitted its responses to the European Medicine Agency (EMA) Day 180 List of Outstanding Issues issued by the Committee for Medicinal Products for Human Use (CHMP) as part of the centralized review process of the Marketing Authorization (MAA) for vosaroxin as a treatment for relapsed/refractory acute myeloid leukemia (AML) in patients aged 60 years and older (Press release, Sunesis, MAR 22, 2017, View Source [SID1234518235]).

"Our team has provided detailed answers to the EMA in response to the Day 180 List of Outstanding Issues," said Daniel Swisher, President and Chief Executive Officer of Sunesis. "We are preparing to go before the Scientific Advisory Group’s Oncology Division (SAG-O) in April, which will assist the CHMP in its evaluation of our application. As we approach this final phase of the European approval process, anticipating a CHMP decision by mid-year, we continue to work in parallel to qualify the best pharma partner to work with us on a European market launch of vosaroxin in the second half of 2017."

About QINPREZO (vosaroxin)

QINPREZO (vosaroxin) is an anti-cancer quinolone derivative (AQD), a class of compounds that has not been used previously for the treatment of cancer. Preclinical data demonstrate that vosaroxin both intercalates DNA and inhibits topoisomerase II, resulting in replication-dependent, site-selective DNA damage, G2 arrest and apoptosis. Both the U.S. Food and Drug Administration (FDA) and European Commission have granted orphan drug designation to vosaroxin for the treatment of AML. Additionally, vosaroxin has been granted fast track designation by the FDA for the potential treatment of relapsed/refractory AML in combination with cytarabine. Vosaroxin is an investigational drug that has not been approved for use in any jurisdiction.

Vosaroxin’s Marketing Authorization Application for relapsed refractory AML is currently under review by the European Medicines Agency, and a regulatory decision regarding approval is expected in 2017.

The trademark name QINPREZO is conditionally accepted by the FDA and the EMA as the proprietary name for the vosaroxin drug product candidate.

AVEO Announces First Patient Dosed in Phase 1/2 TiNivo Trial of Tivozanib and Opdivo® (nivolumab) in Advanced RCC

On March 22, 2017 AVEO Oncology (NASDAQ:AVEO) reported that the first patient has been dosed in the Phase 1/2 AVEO-sponsored TiNivo trial evaluating tivozanib in combination with Bristol-Myers Squibb’s anti-PD-1 therapy, Opdivo (nivolumab), in advanced renal cell carcinoma (RCC) (Press release, AVEO, MAR 22, 2017, View Source [SID1234518233]). The study, which will be led by the Institut Gustave Roussy in Paris, is under the direction of Professor Bernard Escudier, MD, Chairman of the Genitourinary Oncology Committee. The Phase 1 trial will evaluate the safety of tivozanib in combination with nivolumab at escalating doses of tivozanib and, assuming favorable results, is expected to be followed by an expansion Phase 2 cohort at the established combination dose.

"There is compelling scientific rationale for combining the antiangiogenic activity of VEGF inhibition with the immunologic activity of PD-1 inhibitors. Yet, to date, the tolerability of these combinations have been a challenge with currently approved VEGF TKIs and PD-1s," said Professor Escudier. "Tivozanib has been demonstrated to be the most selective VEGF inhibitor, delivering a uniquely favorable tolerability profile in past single agent and combination studies, and has the potential for minimal overlapping toxicities with immunotherapies. I look forward to understanding the clinical potential of combining tivozanib and nivolumab in the TiNivo study, and to the prospect of further improving outcomes in this very dynamic treatment area."

"VEGF-PD-1 combinations have yielded promising tumor response outcomes in renal cell cancer, yet the data presented to date point to challenging or prohibitive toxicity," said Michael Bailey, president and chief executive officer of AVEO. "We believe tivozanib offers a unique opportunity to potentially overcome this barrier, and look forward to initial results from the Phase 1 portion of the TiNivo trial in the first half of 2017."

About Tivozanib

Tivozanib is an oral, once-daily, vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI). It is a potent, selective and long half-life inhibitor of all three VEGF receptors and is designed to optimize VEGF blockade while minimizing off-target toxicities, potentially resulting in improved efficacy and minimal dose modifications. Tivozanib has been investigated in several tumors types, including renal cell, colorectal and breast cancers.

OXIS BIOTECH SCIENTIFIC ADVISORY BOARD MEMBER TO ADDRESS CANCER IMMUNOTHERAPY CONFERENCE IN CHINA

On March 21, 2017 Oxis International Inc. (OTCQB: OXIS) (Euronext Paris OXI.PA) reported that Dr. Daniel Vallera, a member of the Scientific Advisory Board of its wholly owned subsidiary, Oxis Biotech Inc., has been invited to speak at the 15th National Conference of Tumor Immunotherapy on June 22, 2017, in Hefei, China (Press release, OXIS International, MAR 21, 2017, View Source [SID1234539556]).

Dr. Vallera, Director of the section on Molecular Cancer Therapeutics at the University of Minnesota Masonic Cancer Center, said he will discuss two immunotherapy cancer treatments that he helped develop — Trispecific Killer Engager (TriKE) and Bispecific Killer Engager (BiKE). Both platforms have been licensed by Oxis.

The treatments empower the body’s immune system to identify and selectively kill cancer cells, while leaving healthy cells alone.

Dr. Vallera was instrumental in the development of Oxis’ promising cancer therapy, OXS-1550, which is currently in an FDA Phase 1/Phase 2 clinical trial in Minnesota.

The National Conference of Tumor Immunotherapy focuses on research, technology, clinical practice and government policy related to tumor immunology and immunotherapy. About 500 people are expected to attend.

Anthony Cataldo, Chairman and Chief Executive Officer of Oxis, said Dr. Vallera’s invitation is an indication that his work is widely recognized by his peers.

"We have received many requests for more information about the BiKE and TriKE platforms we have licensed from the University Of Minnesota," Mr. Cataldo said. "The biotech community realizes the potential for this technology and how it addresses the future of ‘Targeted Immunotherapy.’"

Dr. Vallera has spent 35 years with the University of Minnesota’s cancer center, where he oversees a laboratory specializing in the development of biological recombinant drugs focusing on bispecific antibody therapies that directly deliver toxic signals to cancer cells.
