CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Genocea Biosciences, Inc. (NASDAQ:GNCA), a biopharmaceutical company developing T cell-directed vaccines and immunotherapies, today reported recent corporate highlights and financial results for the third quarter ended September 30, 2015.

"In early October, we reported positive six-month durability data for GEN-003 which further support its potential to serve as a cornerstone therapy for genital herpes infections with convenient, long-term disease control. We look forward to reporting 12-month data from this ongoing trial in the first quarter of 2016 and to our end of Phase 2 meeting with the FDA later next year," said Chip Clark, president and chief executive officer of Genocea. "Additionally, we are excited to report several recent milestones as part of the expansion of our ATLAS technology into oncology, following encouraging data from our ongoing collaboration with the Dana-Farber Cancer Institute. Having demonstrated its power in infectious disease, we believe that ATLAS is positioned to enable smarter identification of cancer vaccine antigens and smarter immuno-oncology response profiling to optimize patient care."

Business Highlights and Anticipated Milestones

GEN-003 - Immunotherapy for treatment of genital herpes in Phase 2 development. Greater than $1 billion potential revenue opportunity in the U.S.

On October 7, 2015, Genocea reported positive results from a planned interim analysis of data collected six months after dosing from its ongoing Phase 2 dose optimization trial evaluating GEN-003 for the treatment of genital herpes. At its best performing dose of 60 µg per protein / 75 µg of Matrix-M2TM adjuvant, GEN-003 demonstrated a statistically significant 58 percent reduction from baseline in the viral shedding rate (p < 0.0001), the primary endpoint of the study and a measure of anti-viral activity.

In a planned secondary analysis to assess the impact on genital lesion rates, GEN-003 demonstrated sustained and statistically significant reductions from baseline in five of six dose groups ranging from 43 to 69 percent. In addition, the proportion of patients receiving GEN-003 who were lesion-free at six months after dosing ranged from approximately 30 to 50 percent, similar to results reported in Phase 3 clinical trials with oral antiviral therapies. A further secondary analysis measuring the time to first recurrence after completion of dosing showed a range of 152 days to greater than 180 days among dose groups. The Phase 2 trial continues to show that GEN-003 is safe and well tolerated by patients, with no serious adverse events related to the vaccine.

GEN-004 - Vaccine for the prevention of infections by all serotypes of pneumococcus.

On October 19, 2015, Genocea reported that top-line results from a Phase 2a clinical trial for GEN-004 showed consistent reductions versus placebo in the pre-specified endpoints of the rate and density of colonization, but neither of the endpoints achieved statistical significance. GEN-004 was safe and well tolerated by patients. Genocea has suspended development in GEN-004 pending further review of the data and expert consultation.

ATLAS technology platform - Expansion into immuno-oncology

Genocea was founded to create T cell-directed immunotherapies and vaccines using ATLAS, a unique platform for profiling large and diverse patient populations to find the T cell antigens driving protective responses. The Company believes that data reported to date for GEN-003 represents the first evidence of efficacy by an immunotherapy built around new T cell targets for an infectious disease. Building on the success of ATLAS in genital herpes, Genocea initiated a research collaboration with Dana-Farber in 2014 to apply ATLAS in immuno-oncology. This collaboration centered on the potential of ATLAS to identify patterns of T cell response in cancer patients receiving checkpoint inhibitor therapy.

ATLAS makes no assumptions about which cancer antigens are meaningful and which are not. It instead takes a panoramic view of a large, diverse population of human subjects and reveals clinically relevant T cell antigens of protective responses. In contrast to other high-throughput predictive tools currently being applied in oncology drug discovery, Genocea believes that ATLAS has a number of critical benefits, including that it potentially:

These benefits may enable smarter identification of cancer antigens for cancer vaccines and smarter identification of patients best suited to immuno-oncology therapy or therapy combinations.

Dana-Farber Collaboration

In this pilot study, funded by the Ludwig Trust, Genocea partnered with Darren Higgins, Ph.D., professor of microbiology and immunobiology at Harvard Medical School and F. Stephen Hodi, Jr., M.D., director of the Melanoma Center at Dana-Farber Cancer Institute, to conduct a retrospective analysis of 10 checkpoint inhibitor (CPI) treated patients' T cell responses to 23 known tumor-associated antigens. By analyzing the immune responses of both responders and non-responders to CPI therapy, ATLAS successfully identified the cancer antigens to which either (or both) CD4+ or CD8+ T cells became activated. Although this research was not powered to draw firm conclusions, the analysis of T cell responses in patients receiving CPI therapy revealed a pattern indicating a greater breadth of T cell activation for responders than non-responders. The study also revealed preliminary evidence that different characteristics of T cell responses emerge when comparing patients who respond and those who do not. Some T cell responses did not correspond with improved patient outcomes, and may be classified as "decoys," further validating the ability of ATLAS to distinguish clinically relevant targets of T cell responses. This analysis will be presented as a late-breaker at the Society for Immunotherapy of Cancer's (SITC) 30th Anniversary Annual Meeting & Associated Programs in National Harbor, Maryland. The poster, #342, entitled Immunoprofiling of T cell responses in melanoma patients undergoing CPI therapy, will be presented on Saturday, November 7, 2015 between 12.30 - 2:00p.m. ET.

The collaboration with Dana-Farber is ongoing as Genocea continues to analyze more blood samples to characterize T cell response profiles that may be prognostic of CPI efficacy, and to identify T cell antigens that may be included in novel immunotherapies.

Memorial Sloan Kettering Cancer Center Collaboration

The Company today announced a collaboration with Memorial Sloan Kettering Cancer Center to screen the T cell responses of melanoma and non-small cell lung cancer patients treated with checkpoint inhibitors against the complete repertoire of patient-specific putative cancer neoantigens.

The goals of the collaboration are to identify signatures of T cell response in cancer patients associated with response or non-response to CPI therapy and to discover new T cell cancer vaccine antigens. ATLAS will be used in conjunction with Memorial Sloan Kettering's patient-specific cancer neoantigen sequences and blood samples from the same cancer patients. This new collaborative work will be led by investigators Timothy A. Chan, M.D., Ph.D., Vice Chair, Department of Radiation Oncology, and Jedd D. Wolchok, M.D., Ph.D., Chief of Melanoma and Immunotherapeutics Service, Department of Medicine and Ludwig Center.

Epstein-Barr Virus Immunotherapy Program Initiated

Genocea has commenced a new program focused on Epstein-Barr Virus (EBV). EBV infection has been linked to cancers with high unmet needs such as non-Hodgkin's lymphoma, nasopharyngeal carcinoma and gastric carcinoma. We believe the ATLAS platform is highly suited to the creation of a new immunotherapy for EBV given that T cell responses are understood to be crucial for protection against EBV. Furthermore, EBV is part of the herpesvirus family, in which Genocea has deep experience through its development of GEN-003.

Completed $50 million public offering in August 2015.

In August 2015, Genocea closed a public offering of 3,850,000 shares of common stock. Gross and net proceeds to Genocea from this offering were approximately $50 million and $47 million, respectively.

About Genocea

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 immune response. Using ATLAS, its proprietary technology platform, Genocea identifies these targets to potentially enable the rapid development of medicines to address critical patient needs. Genocea's pipeline of novel clinical stage T cell-enabled product candidates includes GEN-003 for genital herpes, GEN-004 for the prevention of infection by all serotypes of pneumococcus, and earlier-stage programs in chlamydia, genital herpes prophylaxis, malaria and cancer immunotherapy.
