Genocea Reports First Quarter 2017 Financial Results and Positive Clinical Developments on Lead Candidate GEN-003 in Genital Herpes

- Data from GEN-003 Phase 2 trial indicate initial course of injections
sustains clinical and virologic efficacy for at least 24 months -

- End of Phase 2 meeting successfully completed for GEN-003; expect to be
Phase 3-ready by end of 2017 -

- Neoantigen cancer vaccine candidate GEN-009 IND filing expected by end of 2017 -

- Conference call today at 9am ET -

CAMBRIDGE, Mass., May 4 , 2017 - Genocea Biosciences, Inc. (NASDAQ: GNCA), a biopharmaceutical company developing T cell-directed vaccines and immunotherapies, today reported financial results for the first quarter of 2017 and announced several positive clinical developments on GEN-003 , the company’s candidate immunotherapy for the treatment of genital herpes.

In a Phase 2 study, GEN-003 demonstrated sustained reductions compared to baseline in the genital lesion rate (percent of days with genital lesions) and the viral shedding rate (percent of days with detectable virus) in genital herpes patients 24 months after dosing across multiple dose groups (see detailed data below). In addition, Genocea has now successfully completed its End of Phase 2 meeting with the U.S. Food and Drug Administration (FDA) and continues to expect GEN-003 to be ready for Phase 3 development by the end of 2017.

Chip Clark, president and chief executive officer of Genocea commented on the results: “These long-term durability data reinforce our conviction that GEN-003 could become the cornerstone treatment for patients with genital herpes. We believe the data suggest a single course of treatment of GEN-003 could offer significant clinical, virologic and convenience benefits to patients generally, and especially those dissatisfied with current treatments, for at least 2 years with no maintenance dosing. Given our successful End of Phase 2 meeting with the FDA, we continue to plan a Phase 3 program design consistent with previous guidance. We believe that these new data, together with the body of positive clinical results to date and these FDA discussions, give us momentum to advance our pioneering product candidate to Phase 3 readiness this year.”

“Since our last earnings announcement,” Mr. Clark added, “we have also progressed our immuno-oncology programs. Together with our advisory board of prominent immuno-oncology experts, we reviewed and refined our development plans for GEN-009, our lead neoantigen cancer vaccine candidate, and we remain confident in our plans to file an IND for this differentiated vaccine candidate this year. Furthermore, we recently presented data on our ATLAS™ antigen identification platform at two important oncology conferences - the Keystone Symposium on immuno-oncology and at AACR 2017 - as well as at the World Vaccine Congress, where we were invited to give an oral presentation on the potential benefits that ATLAS can bring to neoantigen identification and immune response profiling for immuno-oncology.”

GEN-003 Phase 2 Clinical Results
The 24-month clinical results announced today come from an extension of a Phase 2 dose-optimization study that started in 2014 and enrolled 310 subjects from 17 institutions in the United States. Subjects were randomized to one of six dosing groups of either 30 µg or 60 µg of each of two protein antigens paired with one of three Matrix-M TM adjuvant doses (25 µg, 50 µg, or 75 µg). A seventh group received placebo. Subjects received three doses of GEN-003 or placebo at 21-day intervals and no maintenance doses were given. Baseline viral shedding and genital lesion rates were established for each subject in a 28-day observation period prior to the commencement of dosing. This 28-day observation period was repeated immediately after the completion of dosing and at six, 12,


and 24 months following dosing. After the 28-day observation period immediately after dosing, patients in the placebo arm were rolled over across the six active dose groups under a separate protocol. Throughout the trial, GEN-003 continued to demonstrate a safety profile appropriate for its therapeutic setting, as determined by the trial’s independent Drug Monitoring Committee.

Genocea has already advanced the two most promising doses (60 µg per protein combined with either 50 or 75 µg of adjuvant) from this Phase 2 trial into an ongoing Phase 2b efficacy trial, from which positive 6-month, placebo-controlled clinical efficacy data were announced in January 2017 . The efficacy of GEN-003 at these two dose levels over the course of this Phase 2 extension study is as follows:

60 µg per protein /
50 µg of Matrix-M
60 µg per protein /
75 µg of Matrix-M

Anticipated Upcoming Milestones and Events
May 12-16, 2017: AAI’s IMMUNOLOGY 2017™ - Genocea will be presenting the first data from its Epstein-Barr Virus (EBV)-related cancer program, highlighting that ATLAS has identified novel and unexpected antigens of T cell responses in the widely studied, cancer-causing virus.
June 13, 2017: Annual Meeting of Shareholders at the offices of Ropes & Gray in Boston
July 29 - August 2, 2017: 42 nd Annual International Herpesvirus Workshop ( IHW 2017 ) - Genocea will be presenting data on its GEN-003 Phase 2b clinical trial
Mid-2017: GEN-003 12-month Phase 2b data anticipated
4Q 2017: GEN-003 expected to be ready for Phase 3 development
4Q 2017: GEN-009 neoantigen cancer vaccine Investigational New Drug (IND) application filing expected

Financial Guidance
Genocea expects that its existing cash, cash equivalents and investments are sufficient to support its operating expenses, capital expenditure requirements and debt obligations into the first quarter of 2018, without assuming any receipt of proceeds from potential business development partnerships or equity financings. This guidance assumes commencing Phase 3 trials for GEN-003 for genital herpes around the end of 2017 and filing an IND for GEN-009 for cancer by the end of the year, however it is Genocea’s strategy to secure additional sources of financing in advance of starting GEN-003 Phase 3 clinical trials.

First-Quarter 2017 Financial Results
Cash Position: Cash, cash equivalents and investments as of March 31, 2017 were $48.7 million compared to $63.4 million as of December 31, 2016.
Research and Development (R&D) Expenses:  R&D expenses for the quarter ended March 31, 2017 increased $2.4 million, to $9.7 million, from the same period in 2016. The increase was driven by higher compensation, consulting and professional services costs in support of the GEN-003 program and increases in manufacturing costs related to supply for Genocea’s anticipated Phase 3 clinical program. Spending increases on GEN-009 and immuno-oncology programs were more than offset by lower costs on deprioritized infectious disease programs.
General and Administrative (G&A) Expenses:  G&A expenses for the first quarter of 2017 were $3.6 million, compared to $3.9 million for the same period in 2016 reflecting improved operating leverage.


Refund of Research and Development Expense:  A gain of $1.6 million for the quarter ended March 31, 2016 resulted from cash received pursuant to contractual obligations under a collaboration agreement with Isconova AB (“Isconova”) (since acquired by Novavax, Inc.) to refund R&D expenses paid by Genocea to Isconova between 2009 and 2011 relating to the development of the Matrix-M adjuvant technology.
Net Loss:  Net loss was $13.7 million for the quarter ended March 31, 2017, compared to a net loss of $9.8 million for the same period in 2016.

About Genocea Biosciences, Inc.
Genocea is harnessing the power of T cell immunity to develop life-changing vaccines and immunotherapies. While traditional immunotherapy discovery methods have largely used predictive methods to propose T cell targets, or antigens, Genocea has successfully developed ATLAS™, its proprietary technology platform, to identify clinically relevant antigens of T cells based on actual human immune responses. Genocea used ATLAS to identify the antigens in its lead clinical candidate, GEN-003, an investigational immunotherapy to treat genital herpes, and is currently using ATLAS in immuno-oncology applications to develop neoantigen cancer vaccines and to identify T cell response signatures of cancer patients treated with checkpoint blockade therapies to potentially improve clinical practice. Genocea expects GEN-003 to be ready to begin Phase 3 development and to file an IND for its neoantigen cancer vaccine candidate GEN-009 by the end of 2017.
