Item 8.01 Other Events.
On December 9, 2021, SQZ Biotechnologies Company (the “Company”) presented interim results from the highest-dose cohort of its ongoing Phase 1/2 clinical trial of lead Antigen Presenting Cell (“APC”) therapy candidate targeting Human Papillomavirus positive (“HPV16+”) solid tumors at the European Society for Medical Oncology Immuno-Oncology (“ESMO-IO”) Congress. Of the five patients in this cohort evaluable for efficacy, one checkpoint refractory head-and-neck cancer patient showed a radiographic response and symptomatic improvement. The target lesion demonstrated a complete response at both radiographic assessments. At the most recent assessment, the major oropharyngeal lesion demonstrated continued improvement upon physical examination; however, a new dermal lesion was detected. The investigational therapy was well-tolerated, and no dose-limiting toxicities were observed as of October 8, 2021.
Responder Patient Characteristics & Treatment Journey
The patient in the highest-dose cohort who achieved a complete response in the target lesion (patient 17) was a 52-year-old male diagnosed over three-and-a-half years prior to first dose with a locally advanced squamous cell carcinoma of the tonsil, a part of the oropharynx. He initially had chemo-radiation treatment but developed recurrence in the throat and the chest almost two years prior. At trial entry, patient 17 had received six prior lines of therapy, including two combination approaches with the checkpoint inhibitor pembrolizumab.
Patient 17 did not require pre-conditioning. Following a single leukapheresis session, his cell therapy was manufactured in 18 hours and produced 7 doses.

Forward Looking Statements
This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained that do not relate to matters of historical fact should be considered forward-looking statements, including without limitation statements relating to events and presentations, our platform development, our product candidates, clinical activities, progress and outcomes, development plans, manufacturing, clinical safety and efficacy results, therapeutic impact, market opportunities and disease prevalence. These forward-looking statements are based on management's current expectations. Actual results could differ from those projected in any forward-looking statements due to several risk factors. Such factors include, among others, risks and uncertainties related to our limited operating history; our significant losses incurred since inception and expectation to incur significant additional losses for the foreseeable future; the development of our initial product candidates, upon which our business is highly dependent; the impact of the COVID-19 pandemic on our operations and clinical activities; our need for additional funding and our cash runway; the lengthy, expensive, and uncertain process of clinical drug development, including uncertain outcomes of clinical trials and potential delays in regulatory approval; our ability to maintain our relationships with our third party vendors and strategic collaborators; and protection of our proprietary technology, intellectual property portfolio and the confidentiality of our trade secrets. These and other important factors discussed under the caption “Risk Factors” in our Annual Report on Form 10-K, as updated by our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2021 and other filings with the U.S. Securities and Exchange Commission could cause actual results to differ materially from those indicated by the forward-looking statements. Any forward-looking statements represent management's estimates as of this date and we undertake no duty to update these forward-looking statements, whether as a result of new information, the occurrence of current events, or otherwise, unless required by law.
Certain information contained in this press release relates to or is based on studies, publications, surveys and other data obtained from third-party sources and our own internal estimates and research. While we believe these third-party sources to be reliable as of the date of this press release, we have not independently verified, and we make no representation as to the adequacy, fairness, accuracy or completeness of any information obtained from third-party sources.
