Brief summary

This is a single institution, open-label randomized phase 1 trial of neoantigen DNA vaccine alone vs. neoantigen DNA vaccine plus durvalumab in triple negative breast cancer (TNBC) patients following standard of care therapy. Patients with newly diagnosed clinical stage II-III TNBC are eligible for enrollment. Patients will receive standard of care therapy including chemotherapy, surgery and radiation therapy as clinically indicated. Following standard of care therapy, patients will be randomized to receive either a neoantigen DNA vaccine alone, or a neoantigen DNA vaccine + durvalumab.

Interventions

DRUGDurvalumab

-Human monoclonal antibody

-The vaccine will be given by the TDS-IM system

DEVICETDS-IM system (Inchor Medical Systems)

-At each vaccination time point, patients will receive two injections at separate sites.

PROCEDUREPeripheral blood draw

-Baseline, following completion of standard of care therapy, Day 1, Day 57, Day 113, Day 159, and 1 year after initiation of neoantigen DNA vaccine therapy

Secondary

MeasureTime frameDescription
Immune Response to Neoantigen DNA Vaccines Given Alone or in Combination With Durvalumab as Measured by Luminex AssayUp to 1 year after completion of treatment (approximately 1 year and 141 days)-Peripheral blood will be collected at multiple time points before and after vaccination
Number of Participants With an Immune Response to Neoantigen DNA Vaccines Given Alone or in Combination With Durvalumab as Measured by Interferon-gamma ELISPOT AssayUp to 1 year after completion of treatment (approximately 1 year and 141 days)The ELISpot assay was performed after in vitro culture of patient PBMC with neoantigen peptide for \ 12 days. The number of spot-forming T cells, a surrogate for the number of neoantigen-specific T cells, was determined after neoantigen peptide re-stimulation for the duration of the assay (48 hours) and compared to that of control cells that were not re-stimulated with neoantigen during the assay. One-way anova analysis was performed on replicate assessments.
Number of Participants With Immune Response to Neoantigen DNA Vaccines Given Alone or in Combination With Durvalumab as Measured by Multiparametric Flow Cytometry - CD4Up to 1 year after completion of treatment (approximately 1 year and 141 days)Multiparametric flow cytometry was performed as a second readout to assess neoantigen-specific T cell reactivity. Markers included CD4, CD8, IFNγ, and a viability marker. After culture, as described above, T cells were stimulated for 6 hours with/without neoantigen and stained with fluorescent antibodies specific for the various markers. Data were analyzed by comparing the percentage IFNγ+ CD4/CD8 cells between neoantigen-stimulated vs unstimulated T cells; a \>2-fold increase in percentage positive cells after neoantigen stimulation was considered positive.

If a neoantigen-specific T cell response is present, durvalumab will be started on Day 85, and will be administered Q4W at a dose of 1500 mg over the course of 60 minutes. If a neoantigen-specific T cell response is not present, these patients will be replaced but may continue to receive the neoantigen DNA vaccine on study. They will not be transferred to the vaccine-only arm.

Immune Response to Neoantigen DNA Vaccines Given Alone or in Combination With Durvalumab as Measured by Luminex Assay

-Peripheral blood will be collected at multiple time points before and after vaccination

Time frame: Up to 1 year after completion of treatment (approximately 1 year and 141 days)

Population: The luminex assay was not able to be performed.

Number of Participants With an Immune Response to Neoantigen DNA Vaccines Given Alone or in Combination With Durvalumab as Measured by Interferon-gamma ELISPOT Assay

The ELISpot assay was performed after in vitro culture of patient PBMC with neoantigen peptide for \ 12 days. The number of spot-forming T cells, a surrogate for the number of neoantigen-specific T cells, was determined after neoantigen peptide re-stimulation for the duration of the assay (48 hours) and compared to that of control cells that were not re-stimulated with neoantigen during the assay. One-way anova analysis was performed on replicate assessments.

Time frame: Up to 1 year after completion of treatment (approximately 1 year and 141 days)

Population: 4 participants in the Neoantigen DNA vaccine + Durvalumab arm were not evaluable due to early withdrawal from treatment (2=lack of efficacy, 2=withdrawal by subject). 2 participants in the Neoantigen DNA vaccine arm were not evaluable due to early withdrawal from treatment (1=adverse event, 1=only 5 out of 6 vaccines received).

Number of Participants With Immune Response to Neoantigen DNA Vaccines Given Alone or in Combination With Durvalumab as Measured by Multiparametric Flow Cytometry - CD4

Multiparametric flow cytometry was performed as a second readout to assess neoantigen-specific T cell reactivity. Markers included CD4, CD8, IFNγ, and a viability marker. After culture, as described above, T cells were stimulated for 6 hours with/without neoantigen and stained with fluorescent antibodies specific for the various markers. Data were analyzed by comparing the percentage IFNγ+ CD4/CD8 cells between neoantigen-stimulated vs unstimulated T cells; a \>2-fold increase in percentage positive cells after neoantigen stimulation was considered positive.
