Breast Cancer Clinical Trial
Durvalumab and Tremelimumab Before Surgery in Treating Patients With Hormone Receptor Positive, HER2 Negative Stage II-III Breast Cancer
This early phase I trial studies the side effects of durvalumab and tremelimumab before surgery in treating patients with hormone receptor positive, HER2 negative stage II-III breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
I. To evaluate the feasibility of enrolling patients with hormone receptor positive (HR+)/human epidermal growth factor receptor negative (HER2-) breast cancer onto a trial evaluating investigational agents prior to initiating standard neoadjuvant chemotherapy.
II. To evaluate the safety and tolerability of tremelimumab plus durvalumab in patients with HR+/HER2- breast cancer.
I. To assess immunologic/molecular responses to tremelimumab and durvalumab in patients with HR+/HER2- breast cancer who receive the combination therapy.
I. To evaluate the pathologic response in patients with HR+/HER2- breast cancer receiving tremelimumab plus durvalumab prior to initiating standard neoadjuvant chemotherapy.
Patients receive tremelimumab intravenously (IV) over 1 hour and durvalumab IV over 1 hour on day 1. Treatment repeats every 4 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity. Patients then undergo a biopsy and receive standard of care neoadjuvant chemotherapy before undergoing surgery.
After completion of study treatment, patients are followed up until the time of surgery.
Written informed consent and any locally-required authorization (e.g., Health Insurance Portability and Accountability Act [HIPAA]) obtained from the subject prior to performing any protocol-related procedures, including screening evaluations
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Hormone receptor positive (defined as estrogen receptor [ER] and/or progesterone receptor [PR] positive), HER2 negative breast cancer that is clinically staged II-III with no known metastatic disease. ER and/or PR defined as positive if expression > 10% by immunohistochemistry (IHC). HER2 negative or non-amplified as determined by the current American Society of Clinical Oncology-College of American Pathologists (ASCO-CAP) criteria which are as follows: HER2 testing by immunohistochemistry (IHC) as 0 or 1+. If HER2 is 2+, ISH (in situ hybridization) must be performed. HER2 is positive if: IHC 3+ based on circumferential membrane staining that is complete, intense ISH positive based on: 1) Single-probe average HER2 copy number >= 6.0 signals/cell, 2) Dual-probe HER2/CEP17 ratio >= 2.0; c,e with an average HER2 copy number >= 4.0 signals/cell, 3) Dual-probe HER2/CEP17 ratio >= 2.0; c,e with an average HER2 copy number < 4.0 signals/cell, 4) Dual-probe HER2/CEP17 ratio < 2.0; c,e with an average HER2 copy number >= 6.0 signals/cell
Chemotherapy is planned for the patient in the neoadjuvant setting
Hemoglobin >= 9.0 g/dL
Absolute neutrophil count (ANC) >=1.5 x 10^9/L (>= 1500 per mm^3)
Platelet count >= 100 x 10^9/L (>= 100,000 per mm^3)
Serum bilirubin =< 1.5 x institutional upper limit of normal (ULN). This will not apply to subjects with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysis or hepatic pathology), who will be allowed only upon treating physician, principal investigators (PI) or co-PIs approval
Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal unless liver metastases are present, in which case it must be =< 5 x ULN
Creatinine clearance (CL) > 40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance
Female subjects must either be of non-reproductive potential (i.e., post-menopausal by history: >= 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 urine pregnancy test upon study entry
Subject 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
Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site)
Participation in another clinical study with an investigational product during the last 1 month prior to initiation of therapy
Any previous treatment with a PD1 or PD-L1 inhibitor, including durvalumab or an anti-CTLA4, including tremelimumab
History of another primary malignancy except for:
Malignancy treated with curative intent and with no known active disease >= 5 years before the first dose of study drug and of low potential risk for recurrence
Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
Adequately treated carcinoma in situ without evidence of disease e.g., cervical cancer in situ
Has received therapy for this current diagnosis of breast cancer including endocrine therapy or chemotherapy
A single QT interval corrected for heart rate (QTc) >= 470 ms. If an electrocardiogram (ECG) is interpreted to be a prolonged QT interval, 2 additional ECGs will be obtained and the PI will then evaluate all three ECGs and determine whether the patient should be excluded. Mean QT interval corrected for heart rate (QTc) >= 470 ms calculated from 3 electrocardiograms (ECGs) using Fridericia's correction
Current or prior use of immunosuppressive medication within 28 days before the first dose of durvalumab or tremelimumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid
Active or prior documented autoimmune disease within the past 2 years
NOTE: Subjects with vitiligo, Graves disease, or psoriasis not requiring systemic treatment (within the past 2 years) are not excluded
Active or prior documented inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis)
