"This was an exciting quarter for the company as we reported first-in-human data at ASCO (Free ASCO Whitepaper) for our investigational APC cell therapy, which demonstrated an encouraging safety profile, rapid SQZ manufacturing and early signs of immune activity," said Armon Sharei, Ph.D., Chief Executive Officer at SQZ Biotechnologies. "We continue to execute on our APC and AAC clinical programs in oncology, while also making significant strides across our other important therapeutic areas and in developing our manufacturing platform. The quarter’s progress further reinforces the breadth of opportunity for our technology."
Second Quarter 2021 Business and Portfolio Updates
SQZ Antigen Presenting Cell ("APC") Platform in Oncology
Presented initial Phase 1 clinical trial results of SQZ’s engineered APC investigational therapy in patients with advanced or metastatic HPV+ tumors at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper):
SQZ-PBMC-HPV was found to be safe and well-tolerated at all dose levels tested and no dose-limiting toxicity or Grade 3 or higher treatment-related SAEs were observed
Clinical manufacturing feasibility was confirmed with all patient batches produced in less than 24 hours
Analyses of pre- and post-therapy tumor biopsies indicated increased immune activity in select patients. Four out of six patients with less advanced disease achieved stable disease. One patient who achieved stable disease remained on study for over 10 months
Completing fourth Phase 1 monotherapy cohort and progressing towards the combination phase of the study with immune checkpoint inhibitors
SQZ Enhanced Antigen Presenting Cell ("eAPC") Platform in Oncology
Continued progress on eAPC program supports timeline for year-end IND submission to FDA for first clinical candidate. eAPCs incorporate mRNA, which encode multiple activating signals, as well as antigens to potentially enable a more potent CD8 T cell response
SQZ Activating Antigen Carriers ("AAC") Platform in Oncology
Initiating multi-center Phase 1 clinical trial of SQZ-AAC-HPV, the company’s red blood cell-derived investigational cell therapy to treat HPV+ tumors
SQZ Tolerizing Antigen Carriers ("TAC") Platform in Immune Tolerance
Preclinical research presented at the Federation of Clinical Immunology Societies demonstrated that the company’s engineered TACs can drive antigen-specific immune tolerance through key mechanisms relevant to many complex autoimmune diseases
SQZ TACs were found to exert potent bystander suppression, showing the ability to suppress pathogenic T cells with different autoantigen specificities. This finding offers a potential pathway to treating autoimmune diseases without inducing broad immunosuppression
SQZ Manufacturing and Potential Pipeline Expansion Research
Manufacturing data presented at the American Society for Gene and Cell Therapy showed that the company’s manufacturing platform can process 10 billion cells per minute with greater than 90 percent cell viability, and results from the Phase 1 APC trial further indicate the feasibility of the company’s core manufacturing platform to support current therapeutic areas
First-generation prototype of our point-of-care manufacturing platform is now undergoing internal non-clinical testing
Preclinical research presented at the International Society for Stem Cell Research demonstrated that the company’s Cell Squeeze technology can rapidly generate neurons with mature markers using optimized, transient mRNA transcription factor expression. Findings indicate potential to direct cell fate for multiple therapeutic applications
Second Quarter 2021 Financial Highlights
Revenue for the second quarter 2021 was $4.5 million, compared to $6.0 million for the same period last year
Net loss for the second quarter 2021 was $19.1 million, compared to $10.0 million for the same period last year
Research and development expenses for the second quarter 2021 were $17.7 million, compared to $12.0 million for the same period last year. The increase was primarily attributable to planned development and manufacturing costs
General and administrative expenses for the second quarter 2021 were $5.9 million, compared to $4.0 million for the same period last year. The increase was primarily due to an increase in personnel and other corporate-related costs, including stock-based compensation expense and other costs related to operating as a public company
As of June 30, 2021, the company had cash and cash equivalents of $185.1 million and expects this will be sufficient to fund operating expenses and capital expenditure requirements through the first half of 2023
