Genocea Provides Corporate Update, Including First-Quarter 2019 Financial Results

Company anticipates presenting first GEN-009 immunogenicity data at ASCO 2019

Conference call today at 9:00 am ET

CAMBRIDGE, Mass., April 30, 2019 - Genocea Biosciences, Inc. (NASDAQ: GNCA), a biopharmaceutical company developing personalized cancer immunotherapies, today reported its operating and financial results for the first quarter ended March 31, 2019.

“As we say at Genocea, “targets matter,” and we are advancing two programs to demonstrate that target - or antigen - selection plays a large, and underappreciated, role in driving immunotherapy efficacy,” said Chip Clark, Genocea president & CEO. “We expect to present the first immunogenicity data from our ongoing GEN-009 neoantigen vaccine clinical trial at this year’s ASCO meeting in early June, and, assuming positive results, plan to explore the safety and efficacy of GEN-009 in combination with checkpoint inhibitors in patients with a variety of solid tumor cancers. Meanwhile, we are rapidly advancing our GEN-011 neoantigen adoptive T cell therapy, for which we intend to file an Investigational New Drug Application in the first half of 2020.”

Recent Operational Highlights

• Announced a clinical milestone in early January, dosing the first patients and completing enrollment in Part A of the Phase 1/2a clinical trial for GEN-009. The first immunogenicity data from this study are expected to be presented at this year’s meeting of the American Society of Clinical Oncology (ASCO 2019) in early June.

• Completed a private placement financing in mid-February, the first closing of which resulted in gross proceeds of $15.0 million (before deal-related expenses).

• Strengthened senior management team, appointing Diantha Duvall as Chief Financial Officer in early March.

• Presented additional ATLAS data at the 2019 Annual Meeting of the American Association for Cancer Research (AACR 2019) in early April. The poster highlighted the potential use of ATLAS as a tool to predict the advanced melanoma patients for whom checkpoint therapy might prove successful.

First-Quarter 2019 Financial Results

• Cash position: As of March 31, 2019, cash and cash equivalents were $29.0 million versus $26.4 million as of December 31, 2018.

• Research and Development (R&D) expenses: R&D expenses were $6.5 million for the quarter ended March 31, 2019, compared to $7.3 million for the same period in 2018.

• General and Administrative (G&A) expenses: G&A expenses were $3.0 million for the quarter ended March 31, 2019, compared to $3.1 million for the same period in 2018.

• Net loss: Net loss was $15.6 million for the quarter ended March 31, 2019, compared to a net loss of $15.9 million for the quarter ended March 31, 2018.

Guidance

Genocea expects that its existing cash and cash equivalents are sufficient to support its operations into the first quarter of 2020.

About Genocea Biosciences, Inc.

Genocea is a biopharmaceutical company developing personalized cancer immunotherapies. Our unique ATLAS™ technology platform allows us to identify immunotherapy targets based on each person’s tumor antigen-specific T cell responses. Using ATLAS, we can both optimize neoantigens for inclusion in our immunotherapies and exclude so-called “inhibitory” antigens that appear to exert an immunosuppressive effect on the patient. We are advancing complementary programs built from ATLAS insights: GEN-009, our neoantigen vaccine candidate for which we are conducting a Phase 1/2a clinical trial across a variety of solid tumor types, and GEN-011, our neoantigen-specific adoptive T cell therapy, for which we intend to file an Investigational New Drug Application in the first half of 2020.
