Exclusion criteria
Exclusion criteria: ? Underweighted populations - =30kg ? Has evidence of metastatic breast cancer, inflammatory breast cancer, or concurrent bilateral invasive breast cancer where ER is expressed in >10% tumor cells. (Note) Patients with bilateral invasive breast cancers can be enrolled if both tumors are TNBCs, including low estrogen receptor (ER) tumor where ER is expressed in =10% tumor cells. ? Has another malignancy within the last 3 years. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, and thyroid cancer that has undergone potentially curative surgery, or in situ cervical cancer. (Note) These patients should be consulted to the principal investigator for a case-by-case decision before enrollment. ? Has received prior chemotherapy, targeted therapy, radiation therapy, immunotherapy that targets immune checkpoints, co-stimulatory or co-inhibitory pathways for T cell receptors within the past 12 months. ? Any previous treatment with a PD1 or PD-L1 inhibitor, including durvalumab Is currently participating and receiving study therapy, or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of study drug. ? Has received a live vaccine within 30 days of the first dose of durvalumab. Note: Patients, if enrolled, should not receive live vaccine up to 30 days after the last dose of IP. ? Has an active autoimmune disease or inflammatory disorders (including inflammatory bowel disease [eg, colitis or Crohn’s disease], diverticulitis [with the exception of diverticulosis], celiac disease, irritable bowel disease, or other serious gastrointestinal chronic conditions associated with diarrhea, systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves’ disease, rheumatoid arthritis, hypophysitis, uveitis, etc.]) that has required systemic treatment in past 2 years. The followings are exceptions to this criterion: - Patients with vitiligo or alopecia - Patients with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement or psoriasis not requiring systemic treatment. - Any chronic skin condition that does not require systemic therapy - Patients without active disease in the last 3 years may be included but only after consultation with the principal investigator. - Patients with celiac disease controlled by diet alone may be included but only after consultation with the principal investigator. ? Has a diagnosis of immunodeficiency ? Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. The following are exceptions to this criterion: - Intranasal, inhaled, topical steroids, or local steroid injections (eg, intra-articular injection) - Systemic corticosteroid at physiologic dose not to exceed 10 mg/day of prednisone or its equivalent - Steroids as premedication for hypersensitivity reactions (eg, CT scan premedication) ? Has a known history of Human Immunodeficiency Virus (HIV). ? Active infection, including tuberculosis (clinical evaluation that includes clinical history, physical examination and radiographic findings, and tuberculosis testing in line with local practice), hepatitis B, hepatitis C, or human immunodeficiency virus (HIV, positive HIV 1 or 2 antibodies). Active hepatitis B virus (HBV) infection is defined by a positive HBV surface antigen (HBsAg) and positive titer for HBV DNA.
