Immunotherapies such as checkpoint inhibitors and adoptive CAR-T therapies have become foundational treatment options in oncology, yet the majority of patients only receive a temporary benefit or no benefit as they either develop resistance to treatment or are non-responsive to treatment. Novel immunotherapies known as Toll-like receptor (TLR) agonists are a class of immunotherapy that generates both an innate and adaptive immune response which may produce more robust and durable anti-cancer immunity to help overcome resistance.

"We believe targeting innate immunity represents a transformative approach to creating the next-generation of breakthrough therapeutics in cancer immunotherapy," said Dr. Hong I. Wan, president, CEO and co-founder of Tallac Therapeutics. "Our team has generated robust preclinical data on the Toll-like Receptor Agonist Antibody Conjugate (TRAAC) platform that we recently presented at the 2020 Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) annual meeting. With the support of our existing and new investors, I am excited to lead the Tallac team on its mission to advance first-in-class therapies for the benefit of patients in desperate need of new treatment options."

"Tallac has developed a scientifically innovative technology platform to create potent, systemically delivered therapeutics with the potential to provide powerful innate and adaptive anti-tumor immunity across multiple tumor types," said Corey Goodman, board chair, co-founder of Tallac Therapeutics and Managing Partner at venBio. "We are pleased to see the progress made by the team during the seed stage and look forward to supporting Tallac as they advance their pipeline towards the clinic."

Tallac Therapeutics was founded in 2018 by Drs. Goodman and Wan (previously CSO of ALX Oncology) with two other co-founders, Dr. Jaume Pons (currently CEO of ALX Oncology) and Dr. Curt Bradshaw (most recently CSO at Arrowhead Pharmaceuticals), to develop technology for targeted immune activation using an antibody-immune activator conjugate. The research team at Tallac has significant biologics discovery and development expertise. Most recently, under Dr. Wan’s leadership at ALX Oncology, the team designed and advanced ALX148, a best-in-class myeloid checkpoint inhibitor, for multiple tumor indications.

"The enrollment of the first patients into our Phase 1/2a trial is a key milestone for Turnstone and meaningfully advances our aim of transforming the treatment paradigm for people with cancer," said Mike Burgess, Ph.D., President of R&D, Turnstone. "The meticulous design of our differentiated vaccinia virus platform enabled us to engineer RIVAL-01 to deliver three powerful immune modulating agents locally to primary and metastatic tumor sites, by either intratumoral or systemic administration. We look forward to sharing future updates as the study progresses."

Turnstone’s RIVAL therapeutic pipeline is based on its proprietary vaccinia virus platform, which has been engineered for enhanced immune-stimulation and tumor cell selectivity, potent oncolysis and large transgene carrying capacity. The transgenes are designed to be expressed when the vaccinia virus, delivered either intratumorally or intravenously, enters and replicates in cancer cells. The resulting local production of these therapeutics at the site of tumors adds to the inherent oncolytic and microenvironment-modifying properties of the virus to form a powerful multi-modal attack on the disease. RIVAL-01 is being co-developed and co-commercialized under a global collaboration with Takeda.

"Takeda’s partnership with Turnstone continues to gain momentum. Our teams successfully collaborated to establish the RIVAL-01/TAK-605 clinical development plan while simultaneously working together to advance additional novel next-generation multi-payload oncolytic virus concepts to the clinic", said Chris Arendt, Ph.D., Head, Oncology Therapeutic Area Unit, Takeda. "The trial enrollment represents an important step forward in our collaboration and ongoing efforts to leverage innate and adaptive immunity to overcome the limitations of current immuno-oncology therapies."

The RAPTOR trial will evaluate the safety and efficacy of RIVAL-01 (formerly known as TBio-6517) administered intratumorally as a single agent and in combination with Keytruda (pembrolizumab) in patients with solid tumors, including triple negative breast cancer, microsatellite stable colorectal cancer, melanoma and cholangiocarcinoma. Patients are currently enrolling in Phase 1 dose escalation, which will be followed by an expansion phase in specified tumor types in the Phase 2a portion of the trial.

On December 1, 2020 NanoString Technologies, Inc. (NASDAQ:NSTG), a leading provider of life science tools for discovery and translational research, reported the development of a spatial molecular imaging platform, a next generation solution for multiplexed analysis of RNA and protein expression for individual cells within a tissue sample (Press release, NanoString Technologies, DEC 1, 2020, View Source [SID1234572040]).

The spatial molecular imager combines the power of high-plex profiling with high-resolution imaging to enable the analysis of hundreds to thousands of RNAs or proteins directly from single cells within morphologically intact tissue samples. The platform utilizes the company’s advanced Hyb & Seq chemistry, which over the last 18 months has been optimized for in situ spatial analysis. The platform is capable of profiling RNA and protein within a single cell down to sub-cellular resolution in multiple tissue types. To date, prototype systems have imaged RNA from as many as 1,000+ genes simultaneously across thousands of individual cells in Formalin-Fixed Paraffin Embedded (FFPE) tissue.

Tissue biology takes place on several spatial scales including multi-cellular, single cell and the sub-cellular levels. The GeoMx Digital Spatial Profiler (DSP) enables multi-cellular analysis at the whole transcriptome level to elucidate the behavior of populations of cells, such as those within a tumor or the tumor microenvironment. NanoString is developing the spatial molecular imager to address the unmet need for high-plex spatial analysis of single cells and sub-cellular resolution, ideally suited for targeted applications, such as creating cell atlases or studying cell-cell interactions. The GeoMx DSP and the spatial molecular imager are highly synergistic, creating a spatial biology portfolio that spans the continuum from targeted to whole transcriptome analysis, and from multicellular resolutions down to single cell and sub cellular applications.

"Spatial imagers measuring RNA and protein in situ at single-cell and sub-cell resolution are expected to emerge as an important product category over the next several years," said Brad Gray, president and CEO. "Our spatial molecular imaging platform can profile RNA and protein in FFPE with category-leading plex as well as high sensitivity and high resolution. Together, our GeoMx DSP and spatial imager form the leading spatial biology portfolio, spanning from discovery and translational research to clinical diagnostics."

"Researchers and clinicians have gained tremendous insights from the revolution in single cell biology in recent years, but the cellular context was always lost," said Christopher Mason, Ph.D., a geneticist who recently published research using GeoMx. "Now, biological discoveries can be elucidated from high-plex, multi-omic spatial imaging, revealing the key spatial interactions within and between normal or diseased tissues (e.g. COVID-19, cancer) and how these cells communicate and mediate phenotypes, change over time, and respond to therapies."

"Spatial molecular imaging opens up new possibilities to understand the diversity of T-cells infiltrating a tumor at the single cell level without dissociating tissue. Our work under the Technology Access Program has produced results on the location of different T-cell subsets and their interaction with tumors and could reveal which T-cell subsets are most important for controlling tumors," said Evan Newell, Ph.D., Associate Professor, Vaccine and Infectious Disease Division, the Fred Hutchinson Cancer Research Center.

The company plans to provide researchers access to the prototype versions of spatial molecular imaging platform through a Technology Access Program (TAP) beginning in 2021. Under the program, a TAP customer can submit tissue samples to NanoString to be analyzed using the spatial molecular imager and resulting data analysis reported back to the customer by NanoString. Full commercial launch of the spatial imaging solution consisting of instruments, consumables, and software is expected in the second half of 2022.

The Hyb & Seq chemistry was originally developed as part of a hybridization-based sequencing program. The company formed a strategic collaboration with Lam Research, under which Lam Research provided $50 million in funding and access to their industry-leading semi-conductor technology. This collaboration resulted in a robust and scalable chemistry that can be applied to a wide range of applications.

The company is hosting an Investor and Analyst Day webcast at 11:30am ET on Tuesday, December 1st, and will highlight the development program and new capabilities of the platform. Interested parties can access the webcast through the company’s website at View Source The webcast will be available on the company site for 90 days.

On December 1, 2020 Biodesix, Inc. (Nasdaq: BDSX) a leading data-driven diagnostic solutions company with a focus in lung disease, reported publication of an analysis of the company’s Nodify XL2 lung nodule test (Press release, Biodesix, DEC 1, 2020, View Source [SID1234572039]). The test supports clinical decision-making for suspicious nodules by more accurately identifying patients with a very low risk of malignancy and shifting those patients into surveillance, thereby minimizing invasive procedures on those with benign nodules.

In previously published findings from the Pulmonary Nodule Plasma Proteomic Classifier (PANOPTIC) Trial, the Nodify XL2 test was shown to accurately identify patients with lung nodules who have a pre-test risk of malignancy less than 50% as "likely benign." After one year of follow-up, the test demonstrated a sensitivity of 97%, specificity of 44%, and negative predictive value of 98%, which is more accurate than other commonly used lung nodule risk assessment calculators.

The new paper, published in the American College of Chest Physicians (CHEST) Journal, presents findings that all nodules in the study group that were established as benign after one year remained benign after two years of follow-up. This data confirms the performance of the Nodify XL2 test over the guideline-recommended two-year surveillance period to radiologically confirm a benign diagnosis. Additionally, a new analysis suggests that the classifier performs similarly regardless of the whether the nodule of concern was solitary or there were other nodules present.

"This assessment demonstrates our commitment to providing long-term follow-up for patients and to continuously study the performance of our tests," said Scott Hutton, CEO of Biodesix. "Central to our mission is the drive to improve patient outcomes while reducing ineffective and unnecessary treatments and procedures. Nodify XL2 exemplifies this. With this test, part of our Nodify LungTM testing strategy, physicians are equipped with vital and time-sensitive information to help efficiently determine the appropriate course of treatment for each patient."

About Nodify XL2 Lung Nodule Test

The Nodify XL2 blood-based proteomic test helps identify patients who have a suspicious lung nodule that is likely benign or at a reduced risk of being cancerous. Results help physicians to identify patients who may be better candidates for routine CT surveillance to monitor for growth or shrinkage of the nodule over time instead of an invasive diagnostic procedure. The Nodify XL2 test is used for patients who are 40 years or older, have nodules between 8mm and 30mm, and have a pre-test risk of lung cancer of less than or equal to 50%.

The test is performed in Biodesix’s COLA-accredited laboratory in De Soto, Kansas.
