Genocea to Present Positive Preliminary Clinical Data Evaluating Neoantigen Vaccine GEN-009 in Combination with Checkpoint Inhibitors
Webcast/conference call scheduled today,
Three of five patients achieved separate RECIST responses after GEN-009 administration
GEN-009 elicited antigen-specific CD4+ and CD8+ T cell responses in 100% of treated patients
The trial combines GEN-009 with a Standard of Care (SOC) CPI-based regimen approximately four months after the SOC CPI-based regimen is started. The preliminary findings from the first five patients show three achieving independent RECIST responses starting from the first GEN-009 dose. These responses show an acceleration of shrinkage beyond that of the CPI regimen, creating a novel response plot that supports the effect being attributable to the addition of GEN-009. One such patient achieved a complete response (“CR”), while two demonstrated partial responses (“PR”). Overall, two of the first five patients achieved CRs and three experienced PRs.
These results are corroborated by the patients’ immune responses. Neoantigen-specific CD4+ and CD8+ T cell responses were detected in 100% of patients, with all patients responding to multiple vaccinated antigens. Early comparison of T cell responses post-checkpoint (pre-vaccination) and post-vaccination show that T cell responses are specific to GEN-009 and not augmented by checkpoint blockade.
“We are incredibly encouraged by these initial results,” said
“We are very pleased this initial data set continues to validate antigen selection using our proprietary ATLAS™ platform,” said

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 expect to conduct a Phase 1/2a clinical trial.
