ARMOR3-SV Update
Tokai is enrolling patients in its ARMOR3-SV study, a Phase 3 registration clinical trial of galeterone in AR-V7+ mCRPC. The company now expects to complete enrollment in this trial during the second half of 2016 and to have top-line data available by mid-2017. This change in guidance reflects the timing for implementation of the AR-V7 clinical trial assay as well as a delay in initiating clinical sites in Western Europe and Australia during the fourth quarter of 2015. The AR-V7 assay has now been implemented in all regions. Patients are being screened at more than 85 clinical sites globally, and the number of clinical sites is expected to exceed 100 by the end of the first quarter. Notably, AR-V7 prevalence observed in ARMOR3-SV to date has been consistent with the company’s expectations and is in line with the published literature.

"With our rapidly growing number of open ARMOR3-SV clinical sites globally and the implementation of new recruitment initiatives, we believe in our ability to recruit to our revised guidance," said Jodie Morrison, President and Chief Executive Officer of Tokai. "Interest in AR-V7 as a marker for resistance to other therapies continues to increase throughout the prostate cancer community, and we remain focused on our goal of completing ARMOR3-SV as rapidly as possible."

2016 Galeterone Expansion Plans
With the ARMOR3-SV trial building momentum, Tokai now plans to expand galeterone development into broader mCRPC populations, including the initiation of two additional studies during the first half of 2016 in patients who have shown resistance following treatment with either abiraterone or enzalutamide.

The first of these studies is an open-label, two-part Phase 2 clinical trial designed to evaluate galeterone in men whose mCRPC rapidly progressed following treatment with either abiraterone or enzalutamide. The first part of the study will evaluate the rates of prostate-specific antigen (PSA) decline in approximately 36 patients. Following completion of the first part of the study, Tokai may then expand the study to a second, randomized phase that will compare galeterone to the next alternate androgen signaling inhibitor, with efficacy endpoints to include time to PSA progression and rPFS. Tokai plans to evaluate all patients enrolled in this open-label study for the presence of AR-V7, but AR-V7+ status is not a criterion for inclusion in the trial.

The second study is an expansion of an arm of the ongoing Phase 2 clinical trial of galeterone (ARMOR2) in mCRPC patients who have progressed following an initial response to enzalutamide. The expansion of the cohort from nine to 30 patients follows a compelling response seen in a post-enzalutamide patient. This patient did not initially show a PSA response until after seven months of galeterone treatment, at which time the patient’s PSA level rapidly dropped by over 90 percent and has remained at less than 0.1µg/L for over a year. This expanded post-enzalutamide cohort will assess reduction in PSA levels and safety.

About ARMOR3-SV
ARMOR3-SV is Tokai’s pivotal Phase 3 clinical trial of galeterone in men with metastatic castration-resistant prostate cancer (mCRPC) whose tumor cells express the AR-V7 splice variant, a truncated form of the androgen receptor that has been associated with non-responsiveness to commonly-used oral therapies for mCRPC. ARMOR3-SV is designed to evaluate whether administration of galeterone results in a statistically significant increase in radiographic progression free survival as compared to Xtandi (enzalutamide) in 148 treatment-naive mCRPC patients whose prostate tumor cells express the AR-V7 splice variant. ARMOR3-SV is the first pivotal trial in prostate cancer to employ a precision medicine approach for patient selection. Top-line results from ARMOR3-SV are anticipated by mid-2017.

On January 7, 2016 CANbridge Life Sciences reported that it has completed a biomarker study in Chinese patients with glioblastoma multiforme (GBM) for expression of CD95 ligand, the target of its first candidate for clinical development, CAN008, also known as APG101 (Press release, CANbridge Life Sciences, JAN 7, 2016, View Source [SID:1234510067]). The study demonstrated a high degree of CD95 ligand expression consistency between geographically-diverse Chinese and Western GBM patients. CAN008 is a fully-human fusion protein that inhibits the CD95 ligand, a member of the tumor necrosis factor (TNF) superfamily. By blocking the CD95 ligand, CAN008 restores the immune response against tumors and inhibits invasive tumor cell growth.

Based on this confirmatory biomarker study, CANbridge plans to initiate a CAN008 Phase I/II study in newly-diagnosed GBM in Taiwan and expects to dose the first patient in the second half of 2016. In other news, CANbridge announced that it has expanded the licensed territories from Germany’s Apogenix (www.apogenix.com), which is developing APG101 in all other territories, to include Taiwan. In July, CANbridge entered into an exclusive license agreement with Apogenix to develop, manufacture and commercialize APG101 in GBM, with options for other indications, in China, Hong Kong and Macao. Both companies are privately-held.

"The study showing the correlation between Western and Chinese biomarker expression validates our belief that CAN008 is a strong candidate for glioblastoma treatment development in Taiwan and other Chinese territories," said Mark Goldberg, MD, CANbridge Chief Medical Officer and practicing hematologist and oncologist at Brigham and Women’s Hospital and Dana Farber Cancer Institute. "In a Phase II study conducted in Europe, CAN008 showed an improved overall survival benefit in patients with relapsed glioblastoma, especially among patients who expressed the CD95 ligand."

"The results from the biomarker study pave the way for us to advance to our first clinical trial in Asia, executing on our mission to bring promising Western drug candidates to underserved Chinese markets," said James Xue, CANbridge Chairman and CEO. "Brain cancer mortality rates are among the ten highest cancer death rates in China, where the treatment options are even more limited than in the West. We look forward to initiating one of the first immuno-oncology clinical treatment programs in China for this deadly cancer.

On January 07, 2016 Merck, a leading science and technology company reported that it has signed a collaboration agreement with Biocartis for the development and commercialization of a new liquid biopsy RAS biomarker test for patients with metastatic colorectal cancer (mCRC) (Press release, Merck KGaA, JAN 7, 2016, View Source [SID:1234508693]). The test will be developed on Biocartis’ innovative, fully automated molecular diagnostics system, Idylla, which is designed to offer accurate and reliable molecular information from virtually any biological sample in virtually any setting. The new test aims to support clinical practice in performing integrated liquid biopsy RAS biomarker tests, independently of the laboratories’ volume of testing or level of expertise.

Understanding metastatic colorectal cancer (mCRC) patients’ individual biomarker status is key to support timely treatment decision-making.

"Through this collaboration, our desire is to have more metastatic colorectal cancer patients gain access to liquid biopsy RAS testing, regardless of their geographical location," said Rehan Verjee, Chief Marketing and Strategy Officer of Merck’s biopharma business. "As the first pharmaceutical company to collaborate with multiple diagnostic providers of liquid biopsy RAS testing, we are living our commitment to supporting patients and physicians by going beyond treatment. The Biocartis technology will be complementary to other technology previously developed, and will allow for liquid biopsy RAS offerings to a wide range of lab segments, regardless of size and expertise levels."

The Idylla system is a fully automated sample-to-result PCR-based (polymerase chain reaction) molecular diagnostics system. It is designed to offer real-time, reliable and sensitive molecular diagnostic tests. Whereas most of today’s solutions only look for the most prevalent RAS mutations, the Idylla RAS test, comprising two Idylla cartridges, will be designed to detect an extended panel of RAS mutations. In addition, the new test will also provide a BRAF V600 mutation analysis directly integrated with the Idylla RAS test, to allow clinicians to evaluate BRAF and RAS mutation status simultaneously. Based on a direct sample of only 2 ml of blood plasma, the test aims to provide high sensitivity and ease-of-use. The test will be designed to require less than 2 minutes of hands-on time and a turnaround time of approximately 2 hours, enabling clinical decision-making in a timely manner.

"Today, complex diagnostic laboratory infrastructure and specialized expertise requirements are important barriers when it comes to the implementation of personalized medicine on a global scale." said Rudi Pauwels, CEO Biocartis. "We are pleased to partner with Merck, who supports us in putting personalized medicine into daily practice with this collaboration, through the development of rapid and accurate tests on the Idylla system. After having already launched solid biopsy RAS tests, the Idylla liquid biopsy RAS test is a logical next step in our rapidly expanding menu of oncology tests."

Merck and Biocartis plan to implement the Idylla liquid biopsy RAS test in numerous medical centers across the world, excluding the U.S., China and Japan. The test will be available for Research Use Only (RUO) in H2 2016 and is shortly thereafter planned to be submitted for a CE Mark. A concordance study is currently also being undertaken to substantiate the value of the test.

About mCRC
Approximately half of patients with mCRC have RAS wild-type tumors and half have RAS mutant tumors.1 Results from studies assessing RAS mutation status in patients with mCRC have shown that anti-epidermal growth factor receptor (EGFR) monoclonal antibody therapies, such as Erbitux (cetuximab), can improve outcomes in patients with RAS wild-type mCRC.2-6 Colorectal cancer (CRC) is the third most common cancer worldwide, with an estimated incidence of more than 1.36 million new cases annually.7 An estimated 694,000 deaths from CRC occur worldwide every year, accounting for 8.5% of all cancer deaths and making it the fourth most common cause of death from cancer.7 Almost 55% of CRC cases are diagnosed in developed regions of the world, and incidence and mortality rates are substantially higher in men than in women.7

Following a comprehensive review of the Company’s existing operations and development pipeline, as well as an updated assessment of current market dynamics, current and expected future competitive therapies, and the Company’s financial resources, Caladrius has decided to shift greater focus and resources to its growing cell therapy process development, optimization and manufacturing services business at its PCT subsidiary. The rapidly developing cell therapy industry, with several cell-based therapies approaching market approvals which are expected to generate additional demand for commercial manufacturing infrastructure, along with PCT’s continued trend of strong revenue growth, supports the Company’s commitment to focus on growth opportunities for PCT. The Company has also reconfirmed its commitment to pursue further development of its immune modulation platform, with a Phase 2 proof-of-concept clinical trial for a T regulatory cell therapy as the primary focus, while choosing to discontinue the current Phase 3 study of CLBS20 as monotherapy for metastatic melanoma.

"Moving forward, we strongly believe PCT represents a compelling opportunity for near- and long-term shareholder value creation and we intend to continue to invest resources in expanding that business, where we are already experiencing noteworthy year-over-year revenue growth," stated David J. Mazzo, Ph.D., Chief Executive Officer of Caladrius.
"For nearly 17 years, PCT has been an integral partner to the regenerative medicine industry by leveraging its cell therapy-focused, bicoastal development and manufacturing infrastructure to support biotechnology and cell therapy companies," said Robert A. Preti, Ph.D., Chief Technology Officer of Caladrius and President of PCT. "We continue to focus on the design and implementation of sustainable, scalable, reliable and well-controlled manufacturing processes with optimized cost-of-goods as these are all critical success parameters in bringing new cell therapy and immunotherapy treatments to market. We are looking forward to further acceleration of these activities."
Dr. Mazzo continued, "The treatment paradigm in metastatic melanoma was transformed during the course of 2015 by the accelerating adoption of multiple immune checkpoint inhibitors used as monotherapy and in combination treatments. These new drugs have significantly improved outcomes in metastatic melanoma and therefore have altered the opportunity for a monotherapy such as CLBS20 in a landscape that is quickly converting to combination therapies. Therefore, we have concluded that, as designed, our current program in metastatic melanoma will not optimally leverage this asset and we will therefore discontinue the ongoing Phase 3 clinical study with CLBS20 as a monotherapy for the treatment of recurrent Stage III or Stage IV metastatic melanoma. As a result, we will reduce associated staff by approximately 40 employees at our Irvine, California facility. That said, we continue to believe in the potential of CLBS20 as a life-prolonging immunotherapeutic and will pursue licensing or partnership opportunities for its continued development as part of a combination therapy and in different oncology indications. The emphasis will be on collaborating with a company that will allow us to exploit the novel antigen presentation and T cell activation approach of CLBS20."

On the development front, Caladrius will focus its efforts on its T regulatory (Treg) cell therapy product candidate, CLBS03. CLBS03 is based on the Company’s novel immune modulation approach that seeks to restore immune balance by enhancing Treg cell number and function. The Company is planning to commence enrollment in a Phase 2 study for adolescents with recent-onset type 1 diabetes in the first quarter of 2016, in collaboration with Sanford Research, a non-profit research organization that supports an emerging translational research center focused on finding a cure for type 1 diabetes.

"The opportunity provided by polyclonal T cells in the treatment of autoimmune diseases is compelling and we are excited to be at the forefront of this technology’s development and to be working with recognized leaders in the field, such as Drs. Jeffrey Bluestone and Stephen Gitelman of the University of California, San Francisco and Dr. Kevan Herold of Yale University. We believe CLBS03 has the potential to be paradigm-changing in the treatment of recent-onset diabetes and, potentially, other autoimmune diseases. We look forward to initiating our Phase 2 clinical program in conjunction with Sanford Research in the first quarter of 2016," concluded Dr. Mazzo.

Financial Guidance
For 2015, Caladrius expects total revenue to be approximately $23 million, representing an increase of approximately 28% compared with 2014. For 2016, Caladrius expects total revenue to exceed $30 million, representing an increase of greater than 30% compared with the expected results for 2015. In order to accommodate this projected growth, Caladrius has budgeted to spend $6 million in capital improvements to increase PCT’s Allendale, NJ clean room capacity by 60%, and expects to complete the build-out in 2016. Caladrius also estimates that it will incur restructuring charges of approximately $1.0 million in connection with one-time employee termination costs, including severance and other benefits, in the first quarter of 2016. The Company estimates that the staff reduction will result in over $4 million in annualized compensation-related savings, and anticipates significant cost savings associated with terminating the CLBS20 study, which had been estimated to cost $35 million through its completion. In addition, with a narrowed focus on research and development initiatives, as well as a re-sizing of the Company’s general and administrative infrastructure, Caladrius expects to lower R&D, G&A and overall cash burn in 2016 compared to 2015. The Company also expects to incur significant non-cash intangible asset and goodwill impairment charges associated with the termination of the CLBS20 study and will assess the impact as of December 31, 2015 during its annual intangible asset impairment review process.

On January 6, 2016 The Cell Therapy Catapult, the UK organisation dedicated to the growth of the UK cell and gene therapy industry by bridging the gap between scientific research and commercialisation, the University of Birmingham and Cancer Research Technology, the commercialisation arm of Cancer Research UK, reported the launch of a collaboration to develop a new immuno-oncology cellular therapy based on gene modifying T cells to target solid tumours (Press release, Cancer Research Technology, JUN 6, 2016, View Source [SID1234523190]).

The project is aimed at translating an academic discovery programme funded by Cancer Research UK and developed by Dr Steven Lee and Prof Roy Bicknell at the University of Birmingham into a commercially viable cell therapy.

The collaborating partners have launched a new company, Chimeric Therapeutics Ltd. This new company will hold all future IP rights to the resultant discoveries.

The project is based on a new generation chimeric antigen receptor T-Cell (CAR-T) immuno-oncology therapy for solid tumours. This involves directing the CAR-T cell towards a new, highly specific marker of tumour angiogenesis, CLEC14a. This therapy will act as a vasculature disruptive agent compromising oxygen supply to the tumours and inhibiting tumour growth. The technology is currently undergoing the final stages of preclinical development, and is planned to enter into clinical trials soon after.

Cancer Research Technology and the University of Birmingham have partnered with The Cell Therapy Catapult to bring their extensive regulatory, clinical, analytical and manufacturing process development expertise into the program, utilising their experience in developing immunotherapies for cancer. The Cell Therapy Catapult will specifically be involved in the project to accelerate the translation of the academic discoveries made in Birmingham with Cancer Research Technology around CAR-T immunotherapies for solid tumours and the CLEC14a target towards a commercially available cell therapy.

"The Cell Therapy Catapult has extensive experience in working with early stage cell and gene therapies to develop them for clinical trial and commercialisation. We are delighted to assist Cancer Research Technology and Birmingham University to form this new company, Chimeric Technologies and apply this new CAR-T target to address solid tumours for the benefit of patients," said Keith Thompson, CEO, the Cell Therapy Catapult. "The Cell Therapy Catapult look forward to developing partnerships with other Cancer Research UK supported academic groups."

"Scientists at University of Birmingham have demonstrated that these new engineered CAR-T cells exhibit anti-tumour effects and therefore have considerable potential as a therapy," said David Coleman, Head of Spinout Portfolio, University of Birmingham. "We’re delighted to be working with Cancer Research Technology and the Cell Therapy Catapult, through this new spinout company, Chimeric Therapeutics Limited, in order to develop the technology further and into clinical trials."

Dr Phil L’Huillier, Cancer Research Technology’s director of business development, said: "We’re very pleased to partner with the Cell Therapy Catapult and bring their extensive experience to bear on this project. This new partnership builds on a very successful relationship with the University of Birmingham. Immunotherapy is an exciting area in cancer treatment and this technology could provide a powerful route to harness the power of the immune system to block the development of blood vessels, and stop tumours growing."
