Genocea to Present Long-term Follow-up Data from GEN-009 Neoantigen Vaccine at Virtual ASCO 2020
Genocea Biosciences (NASDAQ: GNCA) reports encouraging outcomes from Part A of its Phase 1/2a trial for GEN-009, a neoantigen vaccine. After a median follow-up of one year, 7 out of 8 patients showed no disease progression. The study highlights the vaccine's capability to generate broad T cell responses, with immunity lasting up to 6 months post-vaccination. No significant side effects were noted. The findings will be presented at the 2020 ASCO Annual Meeting, scheduled for May 29-31, 2020.

ATLAS™-identified neoantigens generate broad, sustained T cell responses starting after only 4 weeks and lasting for up to 6 months after the last vaccination
CAMBRIDGE, Mass., May 13, 2020 (GLOBE NEWSWIRE) -- Genocea Biosciences, Inc. (NASDAQ: GNCA), a biopharmaceutical company developing next-generation neoantigen immunotherapies, will present updated durability, safety and immunogenicity clinical data from Part A of its ongoing Phase 1/2a trial for GEN-009, the company’s lead neoantigen vaccine candidate at the virtual 2020 American Society for Clinical Oncology (ASCO) Annual Meeting from May 29-31.
The analysis evaluates eight patients from Part A of the trial who were vaccinated with GEN-009 as adjuvant therapy, focusing on the onset and duration of induced immunity and clinical outcomes. Seven out of the eight patients enrolled have continued without progression with a median follow up of over one year. All patients received dosing as planned with five doses given over a six-month period. No significant adverse side effects were reported with the administration of GEN-009, with only mild symptoms associated with the vaccine adjuvant.
GEN-009 vaccination also generated immune responses across
“I am pleased to see early and durable immune responses and favorable patient outcomes in Part A of the GEN-009 trial,” said Roger Cohen, M.D., Associate Director of Clinical Research, Abramson Cancer Center. “While we can’t assess the specific contribution of the vaccine in the adjuvant setting in this mixed population, the progression-free survival, safety and immunogenicity results support the role that GEN-009 could play in the therapy of multiple tumor types.”
“We are very pleased to find that these patients have done so well with GEN-009 vaccination. The breadth and durability of immune response as well as the clinical outcomes strengthen our excitement to see the effects of combination therapy in patients with measurable tumors,” said Thomas Davis, M.D., Chief Medical Officer of Genocea. “We are eager to elaborate further on our latest GEN-009 findings at the upcoming ASCO meeting and look forward to sharing additional data from Part B of this study on the benefits of the vaccine in patients receiving immune checkpoint inhibitors later this year.”

About Genocea Biosciences, Inc.
Genocea’s mission is to conquer cancer by developing personalized cancer immunotherapies in multiple tumor types. Our unique ATLAS™ platform comprehensively profiles each patient’s T cell responses to potential targets, or antigens, on the tumor. ATLAS enables us to optimize the neoantigens for inclusion in our immunotherapies and exclude inhibitory antigens that can exert an immunosuppressive effect. We are advancing two ATLAS-enabled programs: GEN-009, our neoantigen vaccine for which we are conducting a Phase 1/2a clinical trial and expect preliminary clinical results in the third quarter of 2020, and GEN-011, our neoantigen-specific cell therapy using T cells derived from peripheral blood, for which we intend to file an Investigational New Drug Application in the second quarter of 2020.
