The European patent supplements other Brilacidin-OM patents that have been granted in the United States, Asia (Japan, Taiwan, China), Oceania (Australia) and South Africa. All currently issued patents have an expiration date of 2032. Additional Brilacidin-OM patent applications are pending in other key markets including Russia and South Korea.

The European patent is part and parcel to the Company’s strategy to develop and commercialize Brilacidin-OM internationally through licensing agreements. An estimated 700,000 (source: GLOBOCAN) Head and Neck Cancer (HNC) patients worldwide will develop OM this year, with the figures expected to climb to over one million annually by 2023. In spite of OM incidence rates ranging as high as 100 percent in HNC, there currently are no FDA-approved drugs for the prevention and treatment of OM in these types of cancer patients receiving chemoradiation.

"We are looking at a global product opportunity with OM that is extremely attractive and intellectual property protection is critical. With no approved drugs for our initial target indication in preventing OM in HNC, the first company to commercialize a safe and effective drug would undoubtedly command a significant portion of the market, which is estimated to be at least $1 billion worldwide," said Leo Ehrlich, Chief Executive Officer at Innovation Pharmaceuticals.

"The topline data released yesterday from our Phase 2 trial showed a meaningful reduction in the incidence of severe OM even compared to a rate somewhat lower than historic norms in the placebo arm, demonstrating Brilacidin-OM’s clear effect in preventing this extremely painful, and at times even deadly, consequence of chemoradiation in a majority of HNC patients treated with the drug. I can’t imagine a physician not wanting to prescribe, and a patient not wanting to use, a simple oral rinse like Brilacidin-OM if it would mean cutting the chance of developing severe OM by as much as 38.7 percent, as observed in patients who adhered to the requirements of the trial protocol," Mr. Ehrlich continued.

"Given the positive topline data, the Company is compelled to aggressively seek a development path that will most efficiently bring Brilacidin-OM to patients in need," said Arthur P. Bertolino, MD, PhD, MBA, President and Chief Medical Officer at Innovation Pharmaceuticals. "We intend to work diligently with the FDA and other health authorities, on a worldwide basis, and ideally in collaboration with interested potential partners, to achieve this goal. We have a potential "game changer" asset with Brilacidin-OM, able to make a big impact on a cancer patient’s well-being, and we are in the privileged position of planning wholeheartedly for the next stage of development as we strive to be the first to fill a wide void in oncology as quickly as possible."

On December 12, 2017 Aduro Biotech, Inc. (Nasdaq:ADRO), a biopharmaceutical company with three distinct immunotherapy technologies, reported an update on its clinical development programs for CRS-207, a first-generation proprietary attenuated strain of Listeria that has been engineered to express the tumor-associated antigen mesothelin (Press release, Aduro Biotech, DEC 12, 2017, View Source;p=RssLanding&cat=news&id=2322291 [SID1234522577]). Based on preliminary results from its mesothelioma and ovarian studies, as well as a business and commercial assessment, the company has determined that it will not continue advancement of CRS-207 and will wind down each of its trials in mesothelioma, ovarian and gastric cancer. Aduro will be working closely with investigators to proceed in a manner that is aligned with the best interests of patients still being treated on these studies.

"Although the study did not reach its primary endpoint of superiority in survival, we are encouraged by the higher complete remission rate on the sapacitabine-decitabine arm, especially in the subgroup with low white blood cell count; additional analysis of the data should be pursued," said Hagop Kantarjian, M.D., Professor and Chair, Department of Leukemia, The University of Texas MD Anderson Cancer Center, and chair of the study.

"We are pleased to report detailed results of the SEAMLESS study, which as previously announced, did not reach its primary endpoint," said Spiro Rombotis, President and Chief Executive Officer of Cyclacel. "We believe that the subgroup results have defined a patient population for whom the decitabine-sapacitabine regimen may represent an improvement over low intensity treatment by decitabine alone. We plan to discuss the data, the statistical robustness of the subgroup results and the optimal baseline peripheral white blood cell (WBC) cutpoint with European and US regulatory authorities and will provide updates as appropriate. We are grateful to the patients, their families and the investigators for their contributions to this large study. In parallel, we are progressing our other clinical programs in transcriptional regulation with CYC065 and DNA damage response with sapacitabine-seliciclib in biomarker-selected patients with solid tumors, such as those with BRCA mutations or resistance to existing cancer therapies."

Study Design & Intent-to-Treat Results

The randomized, open label, Phase 3 SEAMLESS study enrolled 482 patients, aged 70 years or older, with newly diagnosed AML who were not candidates for or refused intensive therapy at 110 US and EU sites. Patients were stratified by WBC, antecedent hematologic disorder (AHD), and marrow blasts, and randomized 1:1 to receive either intravenous decitabine administered in alternating cycles with oral sapacitabine versus intravenous decitabine alone.

The trial did not meet its primary endpoint of demonstrating statistically significant improvement in overall survival. A higher complete remission (CR) rate, a secondary endpoint, was observed on the decitabine-sapacitabine arm (17% versus 11%). Other endpoints and safety were similar between the arms.

Prespecified Subgroup Analysis

Baseline WBC

In the less than 10,000 WBC subgroup (n=319) a trend towards improved overall survival (median 8.0 versus 5.8 months, HR=0.84 [0.66, 1.06], p=0.14) favoring decitabine-sapacitabine and a significantly higher CR rate (21.0% versus 8.6%, p=0.0017) was achieved on decitabine-sapacitabine.

In the 10,000 or more WBC subgroup (n=163) significantly better overall survival (median 3.8 versus 5.5 months, HR=1.57 [1.12, 2.19], p=0.007) was observed on decitabine. A trend in CR rate (8.3% versus 15.2%, p=0.18) favoring decitabine was observed but it did not reach statistical significance.

Prior AHD

In the subgroup with prior AHD (n=136) a significantly higher CR rate (16.7% versus 5.7%, p=0.0398) was achieved on decitabine-sapacitabine. There was a numerical difference in median survival (6.4 versus 5.0 months, HR=0.85 [0.59, 1.24], p=0.41) favoring decitabine-sapacitabine but overall survival did not reach statistical significance.

In the subgroup without prior AHD (n=346) there was a numerical difference in median survival (5.9 versus 6.7 months, HR=1.08 [0.86, 1.35], p=0.52) favoring decitabine and CR rate (16.6% versus 12.9%) favoring decitabine-sapacitabine but neither reached statistical significance.

Cytogenetics

In the subgroup with other than unfavorable cytogenetics (n=288) there was a numerical difference in median survival (8.2 versus 5.7 months, HR=0.89 [0.69, 1.15], p=0.38) and CR rate (19.9% versus 11.6%, p=0.16) favoring decitabine-sapacitabine but neither reached statistical significance.

In the subgroup with unfavorable cytogenetics (n=194) there was a numerical difference in median survival (3.8 months versus 5.7 months, HR=1.27 [0.94, 1.73], p=0.12) favoring decitabine but overall survival did not reach statistical significance. There was a numerical difference in CR rate favoring decitabine-sapacitabine (12.0% versus 9.6%) but it did not reach statistical significance.

In the subgroup of patients with below 50% and with 50% or higher bone marrow blasts there were no statistically significant differences in overall survival between the arms.

Presentation

The presentation (abstract 891), titled "Results of a Phase 3 Study of Elderly Patients with Newly Diagnosed AML Treated with Sapacitabine and Decitabine Administered in Alternating Cycles," is available on the Cyclacel website at www.cyclacel.com.

About Sapacitabine

Sapacitabine (CYC682), an orally-available nucleoside analogue, is currently being studied in an ongoing, extension of a Phase 1 study evaluating a combination regimen of sapacitabine and seliciclib, a first generation CDK inhibitor. Parts 1 and 2 of the study evaluated approximately 90 patients with advanced cancers. Part 3 is ongoing in patients with BRCA positive, breast, ovarian and pancreatic cancer. Over 1,000 patients with hematological malignancies and solid tumors have received sapacitabine.

About AML

AML is a rapidly progressing cancer of the blood characterized by the uncontrolled proliferation of immature blast cells in the bone marrow. The American Cancer Society estimates there will be approximately 21,380 new cases of AML and approximately 10,590 deaths from AML in the U.S. in 2017. AML is generally a disease of older adults and the median age is about 67 years. Newly diagnosed elderly patients with poor prognostic risk factors typically die within one year.

On December 12, 2017 Daiichi Sankyo Company, Limited (hereafter, Daiichi Sankyo) and Puma Biotechnology, Inc. (Nasdaq: PBYI) reported a preclinical research collaboration with Memorial Sloan Kettering Cancer Center (MSK) to explore the combination of Daiichi Sankyo’s investigational antibody drug conjugate DS-8201 and Puma Biotechnology’s irreversible pan-HER tyrosine kinase inhibitor neratinib (NERLYNX) in HER2-mutated or HER2-positive solid tumors (Press release, Puma Biotechnology, DEC 12, 2017, http://investor.pumabiotechnology.com/press-release/daiichi-sankyo-and-puma-biotechnology-announce-research-collaboration-major-cancer-cen [SID1234522597]).

A team of scientists led by Maurizio Scaltriti, PhD, and in collaboration with a team of clinical investigators led by Bob Li, MD, will use isogenic models and established patient-derived xenograft models to assess the susceptibility of HER2-mutated or HER2-positive cancers to DS-8201, neratinib and other HER2-targeting therapies, elucidate mechanisms of action and resistance of these various tumor types, and evaluate the potential for synergistic combinations. Daiichi Sankyo and Puma Biotechnology will co-sponsor the research.

"Since early clinical data suggest that DS-8201 may have activity beyond breast and gastric cancers, the archetype HER2-driven tumors, we are interested in studying this asset on a molecular level as well as in combination with other HER2-targeting agents," said Tom Held, Vice President, Global Head, Antibody Drug Conjugate Task Force, Daiichi Sankyo. "In this collaboration, we are examining whether combining DS-8201 and neratinib, with its specific covalent binding to the HER2 receptor and associated increased internalization, is a rational combination therapy strategy to pursue. We are excited to join forces with Memorial Sloan Kettering and Puma to advance the understanding of combining HER2-targeted therapies to potentially treat various forms of HER2-mutated cancer."

"We are pleased to enter into this research collaboration with Memorial Sloan Kettering and Daiichi Sankyo to explore the combination of neratinib and DS-8201," said Alan Auerbach, Puma’s Chief Executive Officer and President. "Combination therapy with agents that address different and complementary pathways, with neratinib targeting the HER2 kinase and DS-8201 providing an innovative targeted delivery of a potent cytotoxic, represents an intriguing approach to the treatment of HER2 mutated tumors and helps to maximize the potential for both agents in treating cancers with a HER2 mutation."

About DS-8201

DS-8201 is the lead product in the ADC Franchise of the Daiichi Sankyo Cancer Enterprise. ADCs are targeted cancer medicines that deliver cytotoxic chemotherapy ("payload") to cancer cells via a linker attached to a monoclonal antibody that binds to a specific target expressed on cancer cells. Designed using Daiichi Sankyo’s proprietary ADC technology, DS-8201 is a smart chemotherapy comprised of a humanized HER2 antibody attached to a novel topoisomerase I inhibitor payload by a tetrapeptide-based linker. It is designed to target and deliver chemotherapy inside cancer cells and reduce systemic exposure to the cytotoxic payload (or chemotherapy) compared to the way chemotherapy is commonly delivered.

DS-8201 is currently in phase 2 clinical development for HER2-positive unresectable and/or metastatic breast cancer resistant or refractory to T-DM1 (DESTINY-Breast01), phase 2 development for HER2-positive advanced gastric resistent or refractory to trastuzumab (DESTINY-Gastric01) and phase 1 development for other HER2-expressing advanced/unresectable or metastatic solid tumors.

DS-8201 has been granted Breakthrough Therapy designation for the treatment of patients with HER2-positive, locally advanced or metastatic breast cancer who have been treated with trastuzumab and pertuzumab and have disease progression after ado-trastuzumab emtansine (T-DM1), and Fast Track designation for the treatment of HER2-positive unresectable and/or metastatic breast cancer in patients who have progressed after prior treatment with HER2-targeted therapies including T-DM1 by the U.S. Food and Drug Administration (FDA). DS-8201 is an investigational agent that has not been approved for any indication in any country. Safety and efficacy have not been established.
