and SARS-CoV-2 continues to progress

Conference call today at 8:30 a.m. E.T.

CAMBRIDGE, Mass., April 29, 2021 (GLOBE NEWSWIRE) —

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



Inhibigens

• 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.
  

SARS-CoV-2

• 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.
  

Guidance

• 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

^TM

, 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.
