Genocea Provides First Quarter 2021 Corporate Update
GEN-011 and GEN-009 immuno-oncology programs continue to advance
Research on Inhibigens™ and SARS-CoV-2 continues to progress
Conference call today at 8:30 a.m. E.T.
CAMBRIDGE, Mass., APRIL 29, 2021 - Genocea Biosciences, Inc. (NASDAQ: GNCA), a biopharmaceutical company developing next-generation neoantigen immunotherapies, today provided a business update for the first quarter ended March 31, 2021.
“Genocea continues to accumulate evidence that our ATLAS™ platform may enable immunotherapies that preferentially attack the surface-presented antigens driving anti-tumor responses or as we say, ‘Targets Matter’,” said Chip Clark, Genocea’s President and Chief Executive Officer. “Whether through our ongoing clinical trials with GEN-011, our neoantigen-targeted peripheral T cell (“NPT”) therapy and GEN-009, our neoantigen vaccine, or through our research efforts with Inhibigens™ and SARS-CoV-2 antigen discovery, we look forward to providing updates consistent with this thesis throughout the year.”
Clinical updates
GEN-011 Phase 1/2a clinical trial (the “TITAN study”)
GEN-011 is in development to treat checkpoint inhibitor-refractory patients. Genocea believes using patient T cells taken from easily accessible peripheral blood and expanding the T cells only on tumor neoantigens prioritized by our ATLAS platform may give GEN-011 efficacy, accessibility and cost advantages over other T cell therapies. The TITAN study is designed to explore safety, biomarkers of activity and anti-tumor efficacy. During the first quarter, Genocea continued to add clinical sites and accrue patients. The company expects to have initial efficacy data from a patient subset late in the fourth quarter of 2021 or the first quarter of 2022.
GEN-009 Phase 1/2a clinical trial
The Company will provide long-term follow-up clinical and immunogenicity data from the ongoing Phase 1/2a clinical study at the American Society of Clinical Oncology (“ASCO”) 2021 Annual Meeting from June 4 - June 8.
Research updates
At the American Association for Cancer Research (“AACR”) Annual Meeting 2021 in April, the Company presented novel preclinical Inhibigen data highlighting that the presence of a single Inhibigen in an otherwise protective immunotherapy can completely reverse the therapy’s intended anti-tumor responses and the Inhibigen effect can be seen as early as 4 days post-dosing.

The Company continues its SARS-CoV-2 research efforts to identify conserved antigens of protective T cell responses that may enable a next-generation vaccine protecting against a wide range of strains.
Other business updates
Strengthened executive leadership team
Genocea appointed Jacquelyn Sumer as Chief Legal and Compliance Officer. Jackie brings over fifteen years of legal experience, including roles at several biopharmaceutical companies with a focus in oncology and cell therapy experience development and commercialization.
Financial and other updates
First quarter 2021 financial results
Cash position: As of March 31, 2021, cash and cash equivalents were $66.0 million compared to $79.8 million as of December 31, 2020.
Research and Development (R&D) expenses: R&D expenses were $8.8 million for the quarter ended March 31, 2021, compared to $10.0 million for the same period in 2020.
General and Administrative (G&A) expenses: G&A expenses were $3.7 million for the quarter ended March 31, 2021, compared to $3.4 million for the same period in 2020.
Net loss: Net loss was $12.0 million for the quarter ended March 31, 2021, compared to $12.9 million for the same period in 2020.
Debt Refinancing
In February 2021, the Company entered into an agreement with Silicon Valley Bank for a $10 million term loan. The proceeds from the loan were used to repay the Company’s outstanding loan from Hercules Capital, Inc., and for general corporate purposes.
Genocea’s operating plan extends its cash runway to the end of 2022.

About Genocea Biosciences, Inc.
Genocea’s mission is to identify the right tumor targets to develop life-changing immunotherapies for people suffering from cancer. Our proprietary ATLAS™ platform comprehensively profiles each patient’s T cell responses to potential targets, or antigens, on that patient’s tumor. ATLAS zeroes in on both antigens that activate anti-tumor T cell responses and inhibitory antigens, Inhibigens™, that drive pro-tumor immune responses. We are advancing two ATLAS-enabled programs: GEN-009, our neoantigen vaccine for which we are conducting a Phase 1/2a clinical trial and GEN-011, our adoptive T cell therapy comprising neoantigen-targeted peripheral cells for which we are conducting a Phase 1/2a clinical trial. In addition to our two clinical programs, we are conducting research in several areas where we believe ATLAS could be a key tool in optimizing antigen selection for therapies across a number of diseases.
