Cancer Cell Paper Identifies "Avidity Enhancement" As New Strategy for Improving CAR T Therapy for Acute Myeloid Leukemia

LUMICKS | May 26, 2022

Cancer_Cell_Paper
LUMICKS, a leading life science tools company that develops instruments for dynamic single-molecule and cell avidity analysis, today announced the publication in Cancer Cell of preclinical research identifying "Avidity Enhancement" as a new strategy to improve therapeutic outcome of  Chimeric Antigen Receptor (CAR) T cell immunotherapy in Acute Myeloid Leukemia (AML).

AML poses significant clinical challenges due to its resistance to therapies and its bleak prognosis. Approximately 20,000 people in the US and 300,000 worldwide die from AML every year, making it the most common form of acute leukemia in adults and a major public health issue.

The Cancer Cell paper (May 9, 2022), entitled "Non-cleavable hinge enhances avidity and expansion of CAR-T cells for acute myeloid leukemia," was authored by a team of CAR T cell researchers led by Dr. Marcela V. Maus, Associate Professor of Medicine at Harvard Medical School and Director of the Cellular Immunotherapy program at Massachusetts General Hospital.

The study details a novel strategy for better cancer treatment with CAR T cells for AML. "Avidity Enhancement", increasing cell-cell binding from both the tumor and CAR T cell side, led to a more effective eradication of tumors in mouse models of AML. In this paper, data generated using the LUMICKS z-Movi® Cell Avidity Analyzer provided superior correlation with CAR T cell activity in vivo compared to the standard in vitro assays in assessing the potency of CAR variants.

Building upon previous research from the Maus Lab indicating 'avidity escape' as an evasion mechanism when CAR T cell therapies are deployed against solid tumors, "avidity enhancement" is a promising strategy for improving clinical success of CAR T therapies.

We continue to be excited about the pivotal research emerging from The Maus Lab and other leading laboratories that demonstrates how researchers can leverage the technological and scientific power of measuring cell avidity with the z-Movi® Cell Avidity Analyzer, This work further solidifies the idea that cell avidity can be a unique biomarker to improve the selection of CAR T therapies for superior therapeutic outcomes in hematological malignancies as well as in solid tumors.  We are delighted to collaborate with researchers worldwide in uncovering meaningful new insights, such as the new treatment approaches suggested for AML contained in this new paper in Cancer Cell."

Andrea Candelli, Ph.D., Chief Scientific Officer of LUMICKS.

The z-Movi Cell Avidity Analyzer measures cell avidity, or level of binding, between immune cells and their targets, enabling researchers to identify the most potent immunotherapeutic effector cells. This unique technology provides predictive, reproducible, and fast results at single-cell resolution. LUMICKS' cell avidity solutions use acoustics to measure forces and interactions between cells, with the goal of shortening the drug development cycle of immunotherapies and reducing failure rates in clinical trials.

Fauna Bio's Comparative Genomics Approach Finds New Compounds for Heart and Lung Diseases

Fauna | June 15, 2022

Fauna Bio, a biotechnology company pioneering the fields of comparative, computational and translational genomics, is celebrating its fourth birthday this month with the release of Centaur, a knowledge graph that is the first of its kind to visualize the intersection between animal gene expression data and human diseases in one comprehensive map. With Centaur, Fauna Bio is able to more rapidly identify human disease indications and targets to generate new therapeutic solutions for some of the most serious human diseases. Orca is another new update to the Convergence platform, and enables direct comparison of gene expression signatures from naturally disease-resistant species with those from humans. Convergence now leverages genomic analyses across 452 mammal species (65 of which are hibernators), an 86 percent increase from two years ago. Much of the company's focus is cardiac and pulmonary diseases, where current treatments mainly focus on symptom management rather than treating the underlying condition. Faun1003, a compound discovered through LEO (Fauna Bio's drug prediction module), is being investigated for use in lung injury and pulmonary hypertension. While uniquely differentiated, retrospective analyses of similar compounds show a survival advantage in critical care settings for patients with lung injury that receive this drug, providing additional human support for the target of Faun1003. Fauna Bio's first neuronal program, Faun264G, looks to improve the survival of human neurons deprived of glucose. A pilot study found knockdown of 264G in-vivo impairs the ability of 13-lined ground squirrels to enter torpor, validating its function. Fauna will continue with expanded in-vivo experiments to understand its role in controlling metabolism this summer. Fauna Bio has also initiated a new discovery program in inflammatory bowel disease, seeking targets to improve epithelial barrier function and reduce immune cell migration. Forty-five percent of compounds predicted for use in IBD by LEO have already been investigated, suggesting strong enrichment for IBD targets. The company has also completed brain cortex and kidney sequencing, with target predictions coming soon. These updates build on the company's momentum since raising $9M in funding last year. Since then, Fauna has expanded partnerships with leading academic institutions, including the University of Wisconsin-Oshkosh and Monash University in Australia. Both collaborations focus on studying genes from the 13-lined ground squirrel that allow for survival during hibernation under extreme conditions. Monash University will assist in additional pre-clinical testing of Fauna compounds, while UW-O supports the existing colony, additional tissue collections, and in-vivo experiments. Through a new partnership with the University of Nevada - Las Vegas, Fauna will add genes from tenrecs, a second hibernating species, to Fauna Bio's proprietary biobank. We continue to see how the power of comparative genomics, and looking outside of our own species, is like building a stronger magnet to help us find that elusive needle in the haystack. By introducing a small amount of the right data and applying it in the right way, we can more quickly identify the real opportunities to make a difference for people suffering from diseases with unmet needs, We've had incredible support from the National Human Genomics Research Institute, the National Institute of Health, our investors, and advisors to continue educating and bringing these programs closer to finding real therapeutic solutions for many of the worst human diseases." Ashley Zehnder, Ph.D., D.V.M, CEO of Fauna Bio. About Fauna Bio Fauna Bio is an end-to-end target and drug discovery platform company and a pioneer in computational, comparative and translational genomics.

Activation of CD8 T cells through MHC-I antigen presentation is a promising approach and is being tested in the SQZ-PBMC-HPV-101 clinical trial where we’ve seen increases in CD8 T cell tumor infiltration and clinical benefit in a refractory patient with HPV16-mediated cancer. We look forward to potentially building on these early results through combination with various immunomodulatory drugs, such as checkpoint inhibitors.” lead author Jong Chul Park, MD, Medical Oncologist, Massachusetts General Hospital Cancer Center, and SQZ® cell therapy trial site investigator SQZ has three ongoing Phase 1/2 clinical trials aiming to drive CD8 T cell responses against HPV16+ solid tumors. Given the broad relevance of CD8 T cell responses across tumors, the authors highlight potential for future expansion of development programs into additional areas such as mutant KRAS, mutant TP53, EBV, and other patient-specific antigens. About SQZ-PBMC-HPV SQZ-PBMC-HPV is the company’s Antigen Presenting Cell (APC) autologous cell therapy clinical candidate and is derived from peripheral blood mononuclear cells (PBMCs), primarily composed of monocytes, T cells, B cells, and NK cells, and engineered with tumor specific E6 and E7 peptide antigens. It received FDA fast track designation in April 2022. In December 2021, the company presented clinical data at the European Society for Medical Oncology Immuno-Oncology (ESMO-IO) congress that included a checkpoint refractory head-and-neck cancer patient who demonstrated a radiographic, symptomatic, and immune response in the monotherapy cohort of the Phase 1/2 clinical trial. SQZ-PBMC-HPV-101 Trial Design SQZ-PBMC-HPV is being evaluated in a Phase 1/2 clinical trial for the treatment of HPV16+ advanced or metastatic solid tumors. Patients must be positive for the human leukocyte antigen serotype HLA-A*02. The investigational candidate, which targets E6 and E7 oncoproteins, is being studied as a monotherapy and in combination with immuno-oncology agents. The study’s primary outcome measures in the monotherapy and combination phases of the trial include safety and tolerability. Antitumor activity is a secondary outcome measure in both the monotherapy and combination phases of the trial, and manufacturing feasibility is a secondary outcome measure in the monotherapy phase of the trial. The monotherapy phase of the study includes escalating dose cohorts with a dose-limiting toxicity (DLT) window of 28 days and is designed to identify a recommended phase 2 dose. The planned combination phase of the study will include SQZ-PBMC-HPV and checkpoint inhibitors. DLT will be measured over 42 days. About Human Papillomavirus Positive Cancers Human papillomavirus (HPV) is one of the most common viruses worldwide and certain strains persist for many years, often leading to cancer. According to the Centers for Disease Control (CDC), in the United States HPV+ tumors represent 3% of all cancers in women and 2% of all cancers in men, resulting in over 39,000 new cases of HPV+ tumors every year. HPV infection is larger outside of the U.S., and according to the International Journal of Cancer, HPV+ tumors account for 4.5% of all cancers worldwide resulting in approximately 630,000 new cases every year. According to the CDC, HPV infection plays a significant role in the formation of more than 90% of anal and cervical cancers, and most cases of vaginal (75%), oropharyngeal (70%), vulval (70%) and penile (60%) cancers. About SQZ Biotechnologies SQZ Biotechnologies is a clinical-stage biotechnology company focused on unlocking the full potential of cell therapies to benefit patients with cancer, autoimmune and infectious diseases. The company’s proprietary Cell Squeeze® technology offers the unique ability to deliver multiple biological materials into many patient cell types to engineer what we believe can be a broad range of potential therapeutics. Our goal is to create well-tolerated cell therapies that can provide therapeutic benefit for patients and improve the patient experience over existing cell therapy approaches. With accelerated production timelines under 24 hours and the opportunity to eliminate preconditioning and lengthy hospital stays, our approach could change the way people think about cell therapies. The company’s first therapeutic applications seek to generate target-specific immune responses, both in activation for the treatment of solid tumors and in immune tolerance for the treatment of unwanted immune reactions and autoimmune diseases.
