"We’re proud to announce that we have just initiated the Phase 1/2a clinical trial for GEN-009, our lead neoantigen vaccine candidate," said Chip Clark, president and chief executive officer of Genocea. "We continue to expect to report the early immunogenicity data from the first patient cohort in the first half of 2019 and remain hopeful these data will provide additional evidence that our ATLAS platform identifies what we call true neoantigens, which we expect to enable more immunogenic and, ultimately, more efficacious vaccines." Mr. Clark concluded, "This is an exciting time at Genocea, as we believe we are well positioned to help transform cancer treatment."

Recent Milestones & Events

April 2018: Genocea scientists presented data at the 2018 Annual Meeting of the American Association for Cancer Research (AACR) (Free AACR Whitepaper) further highlighting the advantages of its ATLAS platform over in silico methods in identifying both neoantigens for vaccine inclusion and "inhibitory" neoantigens for exclusion and detailing the development of a novel model to study the mechanism of inhibitory antigens identified by ATLAS.

April 2018: Genocea filed an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) to begin clinical development of GEN-009.

May 2018: Genocea announced the acceptance of the GEN-009 IND by the FDA. Genocea is currently conducting a Phase 1/2a clinical trial for GEN-009 in patients with a variety of tumor types and expects to report top-line immune response data from the initial patient cohort in the first half of 2019.

Second Quarter 2018 Financial Results

Cash Position: As of June 30, 2018, cash and cash equivalents were $44.2 million compared to $12.3 million as of December 31, 2017.

Research and Development (R&D) Expenses: R&D expenses were $5.3 million for the quarter ended June 30, 2018, compared to $11.4 million for the same period in 2017. This decrease was largely due to reduced headcount, external development, lab, clinical, and other R&D costs.

General and Administrative (G&A) Expenses: G&A expenses were $4.5 million for the quarter ended June 30, 2018, compared to $3.6 million for the same period in 2017. This increase was primarily due to increased consulting and professional services costs, offset by reduced compensation and benefits costs.

Other Income (Expense): Other Income for the quarter ended June 30, 2018 was $5.4 million compared to Other Expense of $0.4 million for the same period in 2017. Other Income for the second quarter of 2018 is

Net Loss: Net loss was $4.4 million for the quarter ended June 30, 2018, compared to a net loss of $15.4 million for quarter ended June 30, 2017.

Financial Guidance
Genocea’s financial guidance is unchanged; the company continues to expect that its existing cash and cash equivalents are sufficient to support its operating expenses and capital expenditure requirements into the fourth quarter of 2019.

During the second quarter, under its existing at-the-market equity offering program (ATM), Genocea sold an aggregate of 3.5 million shares of its common stock, receiving approximately $2.9 million in net proceeds after deducting commissions.

Also during the second quarter, Genocea amended its loan and security agreement with Hercules Capital, Inc., to provide up to $14.0 million in debt financing in the form of a term loan. The previous agreement, entered into in 2014, had provided up to $27.0 million in debt financing. This amended loan agreement provides for interest-only payments until June 1, 2019; this date may be extended should certain performance milestones be met.

Genocea continues to explore strategic alternatives for GEN-003, its Phase 3-ready investigational immunotherapy for the treatment of genital herpes.
