GRAIL | June 06, 2022

GRAIL, LLC, a healthcare company whose mission is to detect cancer early when it can be cured, today announced a broad strategic collaboration with AstraZeneca (LSE/STO/Nasdaq: AZN) to develop and commercialize companion diagnostic (CDx) assays for use with AstraZeneca’s therapies. The collaboration will initially focus on developing companion diagnostic tests to identify patients with high-risk, early-stage disease, with plans to embark on numerous studies across multiple indications over the next several years. The parties are additionally planning to use GRAIL’s technology to enable recruitment of patients with early-stage cancer for AstraZeneca’s clinical studies.

GRAIL has developed a novel approach to detect cancer signals in blood, regardless of whether or not the patient has clinical symptoms. We are excited to embark on this work with AstraZeneca to transform cancer outcomes through a broad, strategic collaboration, Through our collaboration, we hope to provide critical information to improve the identification of patients who may be eligible for clinical trials and change clinical paradigms for the treatment of early-stage cancers."

Sir Harpal Kumar, President, Biopharma Business and Europe at GRAIL.

Across the projects within this collaboration, GRAIL will use its methylation platform to perform testing for patients enrolled in AstraZeneca’s clinical trials. GRAIL will seek regulatory approval in key markets for the liquid biopsy companion diagnostics.

Identifying and treating cancer early is at the heart of this strategic collaboration. Combining GRAIL’s innovative blood-based methylation profiling platform with AstraZeneca’s leadership in Oncology, we hope to accelerate the adoption of circulating tumor DNA across clinical trials and make our cancer medicines available at an earlier stage of disease when there is greater potential to transform patient outcomes, and even cure.”

Susan Galbraith, Executive Vice President of Oncology R&D, AstraZeneca.

GRAIL is developing its proprietary methylation platform for use in multiple post-diagnostic settings to identify patients at high risk of future cancer recurrence, detect the presence or absence of residual disease, and to inform treatment decisions, including identifying patients with cancer who may be eligible for neoadjuvant or adjuvant therapy. GRAIL’s technology platform is designed to optimize circulating tumor DNA testing to enable detection of early stage disease and minimal residual disease (MRD).

SQZ Biotechnologies and Collaborators Publish Technology Review on SQZ® APCs and Effective CD8 T Cell Activation

SQZ Biotechnologies | July 13, 2022

SQZ Biotechnologies Company focused on unlocking the full potential of cell therapies for multiple therapeutic areas, announced the publication of a technical review examining the ability of SQZ® Antigen Presenting Cells to activate CD8 T cells through MHC-I antigen presentation, an approach that may enable a more powerful T cell response and infiltration into solid tumors. Published in ESMO’s Immuno-Oncology and Technology journal, the review further explores the advantages of the company’s Cell Squeeze® technology in cell engineering and manufacturing as well as potential opportunities to develop additional clinical candidates with enhanced capabilities. “In this review, for patients with solid tumors, we discuss the critical need to generate CD8 T cell penetration into the tumor microenvironment. 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.
