Neo Vax (NEO-PV-01)

Collectively, our findings suggest NeoVax did stimulate expansion of neoantigen-specific effector T cells and provide encouraging results to aid in the development of future neoantigen vaccine-based clinical trials in patients with GBM. Herein, we demonstrate the feasibility of incorporating multisector sampling in cancer vaccine design and provide information on the clinical applicability of clonality, distribution, and immunogenicity of the neoantigen landscape in GBM patients.

Here, we report the clinical and immune data from a Phase Ib clinical trial of a personalized neoantigen-vaccine NEO-PV-01 in combination with pemetrexed, carboplatin, and pembrolizumab as first-line therapy for advanced non-squamous non-small cell lung cancer (NSCLC). Neoantigen-specific CD4 T cells generated post-vaccination revealed effector and cytotoxic phenotypes with increased CD4 T cell infiltration in the post-vaccine tumor biopsy. Collectively, these data support the safety and immunogenicity of this regimen in advanced non-squamous NSCLC.

report a phase 1b clinical trial combining a personalized vaccine NEO-PV-01 with chemotherapy and anti-PD-1 pembrolizumab in first-line metastatic non-squamous NSCLC. They demonstrate that this treatment regimen was well tolerated and induced neoantigen-specific CD4 T cell responses with effector phenotype.

NEO-PV-01 in combination with pembrolizumab and carboplatin/pemetrexed has a good safety profile and induces de novo immune responses in first-line non-squamous NSCLC. The association of baseline disease characteristics to prolonged PFS suggests future patient enrichment strategies for evaluation of this novel regimen in a phase 2 trial.

Here, we report the first open-label, phase Ib clinical trial of a personalized neoantigen-based vaccine, NEO-PV-01, in combination with PD-1 blockade in patients with advanced melanoma, non-small cell lung cancer, or bladder cancer...In addition, epitope spread to neoantigens not included in the vaccine was detected post-vaccination. These data support the safety and immunogenicity of this regimen in patients with advanced solid tumors (Clinicaltrials.gov: NCT02897765).
