GEN-003 Phase 3 program expected to initiate in 2H 2017 -

- Conference Call at 9am ET today -

CAMBRIDGE, Mass., Nov. 03, 2016 (GLOBE NEWSWIRE) -- Genocea Biosciences, Inc. (NASDAQ:GNCA), a company developing T cell-directed vaccines and immunotherapies, today reported corporate highlights and financial results for the third quarter ended September 30, 2016. Genocea's lead clinical candidate, GEN-003, is a T cell-directed immunotherapy for the treatment of genital herpes infections, designed to elicit both a T cell and B cell (antibody) immune response that, if approved, the Company believes would be the first-ever therapeutic vaccine for an infectious disease.

"We achieved an important GEN-003 milestone in the third quarter with the selection of our Phase 3 dose, demonstrating a significant reduction in viral shedding for the third consecutive clinical trial, this time with an improved, Phase 3-ready formulation," said Chip Clark, president and chief executive officer of Genocea. "We also continue to advance our immuno-oncology program and are now focusing all of our early stage research and pre-clinical resources to these efforts. We believe ATLAS enables better cancer vaccine antigen selection than existing methods and that our demonstrated vaccine development expertise can be a further competitive advantage in this exciting space."

Mr. Clark continued: "We expect to maintain our strong momentum this quarter and throughout 2017. In December, we will be hosting our first R&D day as we set the stage for the expected start of the GEN-003 Phase 3 clinical trials in the second half of 2017, including the important Phase 2b six month placebo-controlled clinical efficacy data expected in January 2017. We will also set out in detail our maturing immuno-oncology strategy and neoantigen cancer vaccine development plans."

Recent Business Highlights

GEN-003 - Immunotherapy for treatment of genital herpes expected to enter Phase 3 development in 2H 2017.

  • September 2016 - data confirm optimal dose for Phase 3 trials; dose response consistent with T cell therapies and with previous GEN-003 clinical trials
  • October 2016 - IDWeek presentation: GEN-003 induced durable polyfunctional T cells, IgG and neutralizing antibody titers

In September 2016, Genocea announced positive viral shedding data from its ongoing Phase 2b study. The study achieved its primary endpoint, with GEN-003 demonstrating a statistically significant (versus placebo and baseline) 40 percent reduction in the viral shedding rate immediately after dosing in the 60 µg per protein / 50 µg of adjuvant dose group, using a new Phase 3-ready formulation. This result was consistent with a statistically significant (versus placebo and baseline) viral shedding rate reduction of 41 percent at this same dose and time point in the prior Phase 2 trial. Subsequent data from that prior Phase 2 trial demonstrated virologic and clinical efficacy durable through at least one year after dosing.

The 60 µg per protein / 75 µg of adjuvant dose group in the Phase 2b trial reduced the viral shedding rate by 27 percent, a smaller reduction than that observed in the prior trial, and also showed a less acceptable reactogenicity profile than the prior trial. Research has shown that overstimulation of the T cell immune system, as is suggested by this increase in reactogenicity, leads to a loss in efficacy for T cell therapies. We believe the likely driver of this effect is a more potent adjuvant formulation following customary manufacturing process changes to prepare for Phase 3 trials and commercialization.

In October 2016, the Company presented immunogenicity data from its previous Phase 2 trial at IDWeek 2016, the premier annual meeting for healthcare professionals focusing on infectious diseases. These data show that GEN-003 induced antigen-specific polyfunctional T cell responses in immunized subjects, a hallmark of potent T cell immunity. These data also demonstrated that GEN-003 elicited increases in IgG and neutralizing antibody levels above baseline that persisted for one year after the last dose, consistent with viral shedding and clinical symptom reduction seen at 12 months.

Anticipated Milestones and Events


  • Phase 2b 6-month placebo-controlled clinical efficacy data expected in January 2017
  • End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) expected in 1Q 2017
  • Antiviral combination study now planned as part of GEN-003 Phase 3 program

Immuno-oncology collaborations and cancer vaccine strategy

  • Data showing ATLAS's differentiated neoantigen selection capabilities from the ongoing partnership with Memorial Sloan Kettering Cancer Center to be presented at the Society for Immunotherapy of Cancer's (SITC) 31st Annual Meeting & Associated Programs in National Harbor, Maryland. The poster, #374, entitled Genome-scale neoantigen screening using ATLAS™ prioritizes candidates for immunotherapy in a non-small cell lung cancer patient will be presented on Saturday November 12, between 11:45 am and 1:00 pm and 6:45 pm and 8 pm ET
  • Immuno-oncology strategy and neoantigen cancer vaccine development plan update expected at R&D Day in December

Upcoming Events & Presentations

  • Neoantigen Summit 2016, Boston, November 15
  • Stifel 2016 Healthcare Conference, New York City, November 16
  • Piper Jaffray 28th Annual Health Care Conference, New York City, November 30
  • Virtual R&D Day, week of December 12

Updated Financial Guidance:

Genocea now expects that its existing cash, cash equivalents and marketable securities are sufficient to support its operating expenses and capital expenditure requirements into the first quarter of 2018, without assuming any receipt of proceeds from potential business development partnerships, equity financings or debt drawdowns. This guidance is made on the basis of Genocea's current operating plans, which include focusing its research activities on immuno-oncology, conducting the antiviral combination study as part of the GEN-003 Phase 3 program and initiating Phase 3 trials for GEN-003 in the second half of 2017.

Third Quarter 2016 Financial Results

Cash Position: Cash, cash equivalents and investments as of September 30, 2016 were $75.5 million compared to $86.0 million as of June 30, 2016.

Research and Development (R&D) Expenses: R&D expenses for the quarter ended September 30, 2016 increased $2.8 million, to $8.8 million, from the same period in 2015. The increase was driven by increases in headcount and related expenses to support the GEN-003 program and higher clinical costs for the ongoing and anticipated GEN-003 trials. Higher personnel and lab-related costs to advance Genocea's pre-clinical product candidates and develop the ATLAS platform for immuno-oncology also contributed to the increase. These higher R&D costs were partially offset by lower GEN-004 costs due to the Phase 2a trial which was ongoing in the third quarter of 2015 and has since been completed.

General and Administrative (G&A) Expenses: G&A expenses for the quarter ended September 30, 2016 were unchanged at approximately $3.6 million from the same three-month period in 2015.

Net Loss: Net loss was $12.8 million for the third quarter ended September 30, 2016, compared to a net loss of $9.8 million for the same period in 2015.

About Genocea Biosciences, Inc.
Genocea is harnessing the power of T cell immunity to develop life-changing vaccines and immunotherapies. T cells are increasingly recognized as a critical element of protective immune responses to a wide range of diseases, but traditional discovery methods have proven unable to identify the targets of such protective immunity. Using ATLASTM, its proprietary technology platform, Genocea identifies these targets to potentially enable the rapid development of medicines to address critical patient needs. Genocea's pipeline includes GEN-003, a novel T cell-enabled immunotherapy for genital herpes in Phase 2 clinical development, and earlier-stage investments in immuno-oncology.
