"We are very excited to be the first commercial laboratory to launch the Vectra Polaris system for image analysis of circulating tumor cells following ApoStream’s isolation and enrichment functionality," said Darren Davis, PhD, Precision for Medicine Senior Vice President. "Together, these technologies will enable accelerated drug development through detection of biomarkers in liquid biopsies. These tools have enabled our scientists to better understand the biological correlation of circulating metastatic cancer cells with cancer cells present in the tumor tissue."

Circulating tumor cells (CTCs) have long been known to exist in cancer patients’ blood. However, the promise of clinical application of CTCs as a liquid biopsy has not born fruit because these cells are difficult to detect using current molecular biology techniques. Precision for Medicine’s proprietary ApoStream technology captures significant quantities of rare circulating cancer cells from whole blood for characterization using Akoya’s Opal technology and Vectra Polaris imaging platform. ApoStream has been used in more than 80 clinical trials, including several ongoing phase III studies for CDx development.

Akoya’s Vectra Polaris Automated Quantitative Pathology System, part of the company’s Phenoptics 2.0 next-generation biomarker multiplexing platform, enables researchers to gain a deeper level of understanding of disease mechanisms related to new cancer immunotherapy approaches. The Vectra Polaris system integrates high throughput, seven-color multispectral imaging with whole-slide scanning in a simplified digital pathology workflow to support the quantification and analysis of tissue sections discernible with Opal detection kits. A recent meta-analysis of several studies showed that incorporating spatial information using Akoya’s multiplexed immunofluorescence technology is important for improving the predictive accuracy of immuno-oncology biomarkers.

The Phenoptics portfolio is capable of interrogating multiple protein markers on any tissue or cytology slide preparation. Precision for Medicine has validated several immune biomarker panels across various therapeutic applications using both types of preparation. These immune panels are currently being used to monitor immune cell infiltration including cancer, psoriasis, lupus and atomic dermatitis.

"The Vectra Polaris imaging system offers an innovative approach to assessing immunotherapy candidates in translational and clinical research," said Dr. Cliff Hoyt, Akoya Vice President of Translational and Scientific Affairs. "We are pleased to see this technology paired with ApoStream for a comprehensive method of imaging CTCs and improving our understanding of disease mechanisms in cancer."

On November 5, 2019 EpicentRx, Inc., a clinical cancer immunotherapy company targeting both sides of the immune system to deliver cancer treatments with minimal toxicity, reported that it has dosed the first patient in the Phase 3 REPLATINUM trial evaluating RRx-001 for the treatment of third-line and beyond small cell lung cancer (SCLC) (Press release, EpicentRx, NOV 5, 2019, View Source [SID1234550370]). REPLATINUM is EpicentRx’s first Phase 3 study of RRx-001, a small molecule immunotherapy targeting CD47 – SIRPα.

Lung cancer is one of the most common cancers in the world, and the most common cause of cancer-related death. SCLC accounts for about 15% of all lung cancers, with a prevalence of over 300,000 patients globally. Almost 70% of SCLC patients present with extensive-stage disease at time of diagnosis and do not respond well to first- and second-line therapies due to the development of treatment resistance.

"The need for progress in third-line or beyond SCLC is clear, as the outcomes for these patients are uniformly fatal," said Corey A. Carter, M.D., President & CEO of EpicentRx and former head of thoracic oncology at Walter Reed Military Medical Center. "SCLC, especially SCLC in third-line or beyond, is dramatically underserved with ineffective options for patients."

REPLATINUM, an open-label, multicenter, crossover trial designed in collaboration with FDA, will evaluate the efficacy and safety of RRx-001 plus platinum doublet chemotherapy versus platinum doublet chemotherapy alone in 126 patients. REPLATINUM’s primary endpoint is progression-free survival, with overall survival and overall response rate as secondary endpoints.

The REPLATINUM trial follows positive results from EpicentRx’s ongoing Phase 2 QUADRUPLE THREAT trial, which is testing RRx-001 plus platinum chemotherapy in multiple cancer types, including SCLC. In patients with previously treated SCLC, RRx-001 plus platinum chemotherapy dramatically increased response rates, overall survival and progression-free survival compared to historical controls while suggesting a decrease in toxicities from chemotherapy. The QUADRUPLE THREAT data were recently published in the British Journal of Cancer.

"The strength of the Phase 2 trial allows us to keep REPLATINUM at a manageable size and should reduce the time and costs associated with a Phase 3 clinical trial. We are excited to have enrolled the first patient and look forward to working closely with our excellent clinical sites," said Dr. Carter.

RRx-001 has Orphan Drug designation from FDA for SCLC, neuroendocrine cancer and glioblastoma, and from EMA for SCLC.

About RRx-001

RRx-001 is a next generation small molecule immunotherapy being developed by EpicentRx. The therapy targets the CD47 – SIRPα axis and repolarizes tumor associated macrophages (TAMs) and other immunosuppressive cells in the tumor microenvironment to an immunostimulatory phenotype. RRx-001 stimulates the immune system and can be used as monotherapy or in combination with chemotherapy, immunotherapy, radiation and targeted agents, giving the therapy the potential to convert "treatment-resistant" tumors into "treatment-sensitive" tumors. RRx-001 is currently in the Phase 3 REPLATINUM trial for the treatment of third-line and beyond small cell lung cancer (SCLC). RRx-001 is also in the Phase 2 QUADRUPLE THREAT trial for the treatment of SCLC, non-small cell lung cancer, neuroendocrine tumors, ovarian and prostate cancer, and the Phase 2 PREVLAR trial for the prevention of oral mucositis. Clinical studies for the drug have also been conducted for the treatment of colorectal cancer, brain metastases and glioblastoma.

On November 5, 2019 Bicycle Therapeutics plc (NASDAQ: BCYC) a clinical-stage biotechnology company pioneering a new and differentiated class of therapeutics based on its proprietary bicyclic peptide (Bicycles) technology, reported that new preclinical data from BT7480, a potent tumor-targeted immune cell agonist (TICA) targeting Nectin-4 and agonizing CD137 (4-1BB), will be presented during speaker and poster sessions at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper)’s (SITC) (Free SITC Whitepaper) 2019 Annual Meeting on November 6-10, 2019 in National Harbor, MD (Press release, Bicycle Therapeutics, NOV 5, 2019, View Source [SID1234550369]).

"Our novel and proprietary Bicycle tumor-targeted immune cell agonists, or TICAs, are fully synthetic approaches engineered to overcome the limitations of other immunomodulatory mechanisms," said Kevin Lee, Ph.D., Chief Executive Officer of Bicycle Therapeutics. "The constrained nature of Bicycles confers high affinity and selectivity and enables us to easily link tumor targeting Bicycles to Bicycles that agonize CD137, providing tumor-specific effects. In preclinical experiments with BT7480, we have shown these characteristics promote rapid tumor penetration and powerful anti-tumor activity. We believe that these features, along with the modular nature of the Bicycle platform, could position Bicycles at the cutting edge of next generation immuno-oncology treatments and we look forward to progressing BT7480 into IND-enabling studies."

BT7480 has shown very potent and tumor antigen dependent CD137 agonism in ex vivo experiments using patient-derived lung tumor samples that have intact immune microenvironments. In a Nectin-4 overexpressing syngeneic tumor model, 92% (n=24) of animals dosed with BT7480 experienced complete tumor regressions. Five of the complete responder animals were subsequently re-challenged with the same tumor cell implantation and no tumor growth was observed, implying development of immunogenic memory. In addition to these data on BT7480, the Company will also present preclinical data at SITC (Free SITC Whitepaper) on other emergent Bicycle TICA strategies.

The presentation, titled "SBT6050, a HER2-Directed TLR8 Agonist Antibody Conjugate, Designed to Overcome Primary Resistance to and Synergize with Checkpoint Inhibition in HER2-Expressing Tumors," shows the potential for ImmunoTAC SBT6050, a novel therapeutic comprised of a potent TLR8 agonist conjugated to a HER2-directed monoclonal antibody, to drive robust anti-tumor efficacy as a single agent and in combination with checkpoint inhibition. SBT6050 potently activates myeloid cells in a HER2-dependent manner, resulting in the stimulation of multiple anti-tumor immune mechanisms and enabling tumor-localized activity via systemic delivery. In preclinical tumor models refractory to checkpoint inhibition, including T cell deficient xenograft models, an SBT6050 surrogate led to curative single-agent efficacy. Moreover, the single agent efficacy of the SBT6050 surrogate in an immune-competent, checkpoint refractory tumor model was enhanced when combined with an anti-PD1 agent. These preclinical data demonstrate the ability of activated myeloid cells to drive robust anti-tumor efficacy and support clinical evaluation of SBT6050 as a single agent and in combination with checkpoint inhibition in HER2-expressing tumors.

"These data continue to demonstrate the ability of Silverback’s technology to localize delivery of potent therapies to specific sites in the body," said Valerie Odegard, Ph.D., Silverback’s chief scientific officer. "Our preclinical data highlight SBT6050’s ability to activate T cell dependent and independent anti-tumor mechanisms, and its potential to be efficacious as a single agent and in combination, even in settings where immunotherapy has traditionally been ineffective. We look forward to initiating clinical investigation of SBT6050 in 2020."
