Breast Cancer Clinical Trial
Adjuvant PVX-410 Vaccine and Durvalumab in Stage II/III Triple Negative Breast Cancer
The purpose of this research study is to evaluate Immunotherapy with a peptide vaccine and Programmed Death Ligand 1 (PD-L1) inhibitor as a possible adjuvant treatment for Stage II or III Triple Negative Breast Cancer. This research study is studying the safety, tolerability, and immune response of these treatments.
The names of the study interventions involved in this study are:
This research study is a Phase Ib clinical trial, which tests the safety of an investigational intervention and also tries to better understand how the investigational intervention affects the body. "Investigational" means that the intervention is being studied.
The FDA (the U.S. Food and Drug Administration) has not approved PVX-410 and Durvalumab as a treatment for any disease.
Durvalumab is a protein that affects your immune system by blocking the PD-L1 pathway. The PD-L1 pathway controls the body's natural immune response, but tumors can interrupt this pathway and partially resist or escape the immune system. By blocking the PD-L1 pathway, Durvalumab may help the immune system identify and catch tumor cells.
PVX-410 is an investigational vaccine that is being developed to treat multiple myeloma and triple negative breast cancer.
In this research study, the investigators are studying the body's immune response to the PVX-410 study vaccine in combination with Durvalumab. This study will help researchers understand if the vaccine and Durvalumab can work together to help the body's immune system recognize triple negative breast cancer. The investigators are also studying the safety of the PVX-410 vaccine alone and together with the Durvalumab.
Written informed consent and any locally-required authorization obtained from the patient prior to performing any protocol-related procedures, including Screening evaluations.
Females, ≥18 years at time of study entry.
HLA-A2 positive by deoxyribonucleic acid (DNA) sequence analysis (by history or as part of this study).
Histopathological diagnosis of triple negative breast cancer(TNBC) (ductal, lobular, mixed or metaplastic), defined as estrogen receptor (ER)<1%, progesterone receptor (PR)<1%, and Human Epidermal growth factor Receptor 2 (HER2) negative according to American Society of Clinical Oncology/College of American Pathologists guidelines by local testing according to institutional standards. For tumors with equivocal interpretation of receptor status (e.g. "weak" or "faint" staining, the Principal Investigator will have final determination of triple negative status.
Completed all planned therapy for Stage II or III TNBC (American Joint Committee on Cancer, 7th Edition) meeting the following guidelines:
received neoadjuvant chemotherapy with residual invasive disease at surgery and/or completed adjuvant chemotherapy with or without radiation. (The patient may have had adjuvant and/or neoadjuvant chemotherapy for their disease). Adjuvant/neoadjuvant chemotherapy regimens must include at least 4 cycles of a standard chemotherapy regimen, and generally this should include one of the generally accepted standard regimens (including but not limited to: Adriamycin/Cytoxan-Taxol, Taxotere/Cytoxan, Adriamycin/Cytoxan, or Cytoxan/Methotrexate/Fluorouracil). For patients who received their standard chemotherapy as part of a clinical trial, the regimen should include at least 4 cycles of therapy.
All planned radiation therapy surgery for the treatment of the current cancer should be complete (not including plastic or reconstructive surgery).
Patients with local-regional recurrence without evidence of distant metastases (no definite stage IV disease) who are treated with curative intent may be eligible following completion of all surgery and/or chemotherapy and/or radiotherapy. Such patients must have no evidence of residual disease by standard clinical and radiological examination (per Investigator discretion) following completion of curative intent treatment.
Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 (see Appendix B).
Adequate normal organ and marrow function as defined below:
Hemoglobin ≥9.0 g/dL.
absolute neutrophil count (ANC) ≥1.5 109/L (≥1500 per mm3).
Platelet count ≥100 109/L (>100,000 per mm3).
Serum bilirubin ≤1.5 institutional upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology).
aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ≤2.5 ULN.
gamma-glutamyltransferase (GGT), lactate dehydrogenase (LDH), and alkaline phosphatase ≤2.5 ULN.
Serum creatinine clearance >40 mL/min by the Cockcroft-Gault formula 72 or by 24-hour urine collection for determination of creatinine clearance:
Creatinine Clearance (mL/min) = Weight (kg) x (140 - Age) 0.85 72 x serum creatinine (mg/dL)
Negative virology/serology for human immunodeficiency virus (HIV)-1, HIV-2, hepatitis B (surface antigen), and hepatitis C.
Female patients must either be of non-reproductive potential (i.e. post-menopausal by history of age ≥60 years old and no menses for 1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy test (β-human chorionic gonadotropin (HCG)) at the Screening visit. (If Screening visit pregnancy test was completed within 7 days of first treatment visit it does not need to be repeated. Patients with a negative pregnancy test at Screening beyond 7 days prior to treatment, but who otherwise meet all other criteria, may be registered to study but must have a repeat negative serum pregnancy test within 7 days of treatment and such testing may be done on day of first treatment prior to administration).
If not postmenopausal or surgically sterile, study patients must be willing to practice at least one of the following methods of birth control for at least a menstrual cycle before and after study drug administration: (1) Total abstinence from sexual intercourse with a male; (2) Sexual intercourse with vasectomized male partner; (3) Other acceptable forms of birth control (condoms, contraceptive sponge, diaphragm or vaginal ring with spermicide or cream); (4) Use of an intrauterine contraceptive device.
Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
