"SQZ’s vision is to improve patient care by creating transformative cell therapies that can be broadly accessible around the world through rapid, cost-efficient manufacturing," said Armon Sharei, Ph.D., CEO and Founder at SQZ Biotechnologies. "We are advancing these important goals through the development of our POC manufacturing system, which has the potential to substantially improve the accessibility and economic feasibility of cell therapies. Through our collaboration with STEMCELL, we intend to broaden technology access for research use and hope to facilitate advancement of the cell therapy field by the life sciences community."

"This is an exciting collaboration that combines STEMCELL’s life sciences research and product development capabilities with SQZ’s cell engineering expertise," said Allen Eaves, M.D., Ph.D., President and CEO of STEMCELL Technologies. "The development of this RUO system, which will be well complemented by our various cell isolation and culture product portfolios, will provide the research community with a significant opportunity for their cell engineering investigations. By adapting the proven Cell Squeeze technology, with its ability to deliver multiple biological cargoes to a range of cell types, we anticipate the RUO system will offer enhanced flexibility to the scientific community. We look forward to our continued collaboration with SQZ and the development of this system."

SQZ’s Cell Squeeze technology has enabled the development of three oncology therapeutic candidates in active Phase 1/2 clinical trials. In addition to these programs, the company intends to file its first IND using the POC system for a SQZ TAC clinical candidate against celiac disease in the first half of 2023. The Cell Squeeze technology has also led to a number of preclinical developments in the areas of infectious disease and cell regeneration.

SQZ’s automated POC manufacturing system in development integrates, among other things, cell isolation, cell washing, intracellular delivery, and product filling. The system is designed to process patient material within a closed, single-use sterile disposable kit. The prototype system offers the potential to be operated outside of a clean room—which could ultimately allow decentralized cell therapy manufacturing by SQZ POC systems in a variety of care settings. SQZ will present data from the initial non-clinical studies of the POC system at ASGCT (Free ASGCT Whitepaper).

STEMCELL Technologies will present data from the first functional study findings for the RUO system at the ASGCT (Free ASGCT Whitepaper) Annual Meeting. The data will demonstrate an ability to efficiently deliver cargoes to primary immune cell types.

Due to the unique structural features of EGFR exon20ins proteins, most approved EGFR TKIs are not active against them. Sunvozertinib (DZD9008) was designed with the goal to address the limitations of existing therapies. It is an irreversible inhibitor targeting EGFR exon20ins as well as EGFR sensitizing, T790M and uncommon mutations while maintaining selectivity against wild-type EGFR. Sunvozertinib shows potent antitumor activity against EGFR exon20ins mutations at the enzymatic and cellular levels, and in patient-derived xenograft and transgenic animal models. These findings support the ongoing clinical development of sunvozertinib for the treatment of EGFR exon20ins NSCLC. Commenting on the findings, Prof. Pasi Jänne of Dana-Farber Cancer Institute and Harvard Medical School, a lead investigator of the study and the corresponding author of the paper, said "sunvozertinib was well tolerated in the study. Antitumor efficacy was observed at the doses of 100 mg and above in patients with EGFR exon20ins NSCLC across different subtypes, with prior amivantamab treatment as well as with baseline brain metastasis. Its best ORR was 48.4%." Based on the data, sunvozertinib has been granted Breakthrough Therapy Designation by US FDA and China CDE.

"This is yet another milestone achievement for the team. Like Breakthrough Therapy Designation from US and China, it reflects the quality of Dizal’s science. The data published further demonstrated sunvozertinib’s enormous potential for bringing meaningful benefits to lung cancer patients." said Dr. Xiaolin Zhang, CEO of Dizal. "At Dizal, we strive to bring differentiated therapies to treat devastating diseases. We have now established an internationally competitive portfolio with two leading assets in the global pivotal studies."

Cancer Discovery, a journal of the American Association for Cancer Research (AACR) (Free AACR Whitepaper), publishes high-impact, peer-reviewed articles describing major advances in research and clinical trials [1]. As the premier cancer information resource, the Journal presents articles from the world-class universities and top-notch oncology research institutions.

About EGFR Exon20ins NSCLC

Lung cancer is the leading cause of cancer death in the world. It is classified broadly as non-small cell lung cancer (NSCLC), accounting for 85% lung cancer cases, and small cell lung cancer (SCLC). EGFR mutation is common in NSCLC. About 4–12% of all EGFR mutations are insertions at exon 20 (EGFR exon20ins) [2]. Patients with EGFR exon20ins generally don’t respond to the currently available EGFR TKIs.
