Brief Summary:
This phase I trial studies how well anti-PD-L1/TGFbetaRII fusion protein M7824 (M7824) works in treating patients with stage II-III HER2 positive breast cancer. Immunotherapy with M7824 may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Detailed Description:


I. To evaluate the change in tumor-infiltrating lymphocytes (TIL) percentage pre and post M7824 therapy.


I. To evaluate the safety and tolerability of M7824 in early stage breast cancer (stage II/III).

II. To evaluate pathological response at the time of surgery after 2 doses of M7824 followed by neoadjuvant (human epidermal growth factor receptor 2) HER2 targeted therapy in combination with chemotherapy of physician's choice.


I. To evaluate imaging based response to M7824. II. To evaluate potential systemic and tumor based predictive biomarker candidates of response.

III. To evaluate immune responses induced by exposure to M7824 systemically and in tumor microenvironment (TME).


Patients receive anti-PD-L1/TGFbetaRII fusion protein M7824 intravenously (IV) over 1 hour on days 1 and 15. During days 28-56 patients receive planned neoadjuvant chemotherapy.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 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
  • Tumor size >= 2 cm and with no known distant metastatic disease
  • HER2+, breast cancer as defined by American Society of Clinical Oncology (ASCO)-College of American Pathologists (CAP) guidelines: HER2/neu is defined as positive: immunohistochemistry (IHC) 3+ based on circumferential membrane staining that is complete, intense in situ hybridization (ISH) positive based on: single-probe average HER2 copy number >= 6.0 signals/cell. Dual-probe HER2/CEP17 ratio >= 2.0; with an average HER2 copy number >= 4.0 signals/cell, dual-probe HER2/CEP17 ratio >= 2.0; with an average HER2, copy number < 4.0 signals/cell, dual-probe HER2/CEP17 ratio < 2.0; with an average HER2, copy number >= 6.0 signals/cell, neoadjuvant systemic therapy is planned and will include HER2 targeted therapy in combination with chemotherapy of physician's choice
  • Hemoglobin >= 9 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 investigator (PI) or co-PI 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
  • Serum creatinine clearance >= 60 mL/min by the Cockcroft-Gault formula or by 24-hour urine collection for determination of creatinine clearance

Male subjects on study must also use highly effective contraception. Highly effective contraception must be used 30 days prior to first trial treatment administration, for the duration of trial treatment, and at least for 4 months after stopping trial treatment.
