Detailed Description
This is a phase II, open-label, randomized window of opportunity trial evaluating the immunologic effects within the tumour, microenvironment, and host blood of patients treated with either
- Arm A: Cemiplimab (n=10)
- Arm B: Cemiplimab + Dupilumab (n=10) administered prior to surgery. Randomization will be at 1:1 ratio in patients newly diagnosed with primary operable ER+* HER2- invasive breast cancer awaiting surgery in the next 4-6 weeks who are not planned for neoadjuvant therapy.
Primary Hypothesis: In ER+ breast cancer, blockade of IL-4 signalling using dupilumab enhances anti-tumor immunity (through reduced Th2 skewing) when used in combination with PD-1 inhibitors (Cemiplimab) compared to PD-1 inhibition alone in ER+ breast cancer
Primary Objective:
• To determine whether addition of dupilumab to cemiplimab reduces TH2 skewing of the tumor, tumor microenvironment (TME) and blood in patients with ER+ breast cancer
Secondary Objectives:
- To evaluate dynamic changes in immune cell populations as measured by in situ proteomics
- To characterize the safety of a short-term duration of the combination of dupilumab with cemiplimab in patients with ER+ breast cancer awaiting surgery
Exploratory Objective:
• To test the effect of tumor PD-1 gene expression and its effect on the immune response in treated and untreated patients
This is a window of opportunity trial which will require administration of cemiplimab or combination of cemiplimab + dupilumab prior to surgery. Surgery will be a minimum of 96 hours to 2 weeks after the cemiplimab. Patient follow-up after surgery will be for a period of 30 days post-surgery.
Target: 20 patients (10 in Arm A and 10 in Arm B). Accounting for screen failures and withdrawals (20%), 24 patients will be accrued.

Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Female patients with newly diagnosed histologically confirmed primary invasive breast cancer currently not undergoing any treatment while awaiting surgery.
- Invasive ductal or lobular carcinoma, invasive carcinoma Not Otherwise Specified (NOS)
- ER+ breast cancer (1-10%*) of any size. ER positive tumor defined ≥1% positively staining cells by immunohistochemistry, according to the current American Society of Clinical Oncology (ASCO) / College of American Pathologists (CAP) guidelines.
- The participant is eligible for surgery within the next 4-6 weeks.
- HER2/neu must be negative by immunohistochemistry (IHC) defined as IHC 0 or 1+ or fluorescence in situ hybridization (FISH) or other ISH methods with a ratio of < 2 according to current ASCO (American Society of Clinical Oncology)/CAP guidelines.
- Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2.
- Age ≥18 years.
- The participant (or legally acceptable representative if applicable) is able to provide written informed consent for the study.
Exclusion Criteria:
- Known or suspected breast cancer metastasized to distant organ (lung, liver, bone, brain, abdomen)
- Prior therapy with any chemotherapy or endocrine for breast cancer or other cancers within last 3 months
- Pre-dominant histology other than invasive ductal or lobular carcinoma or invasive carcinoma NOS.
- Patients with an active infection or an absolute neutrophil count < 1.5 x 10^9/L.
6. Patients with pre-existing renal impairment, Creatinine clearance calculated by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation of less than 50 mL/min/1.73m2.
7. Known or current history of pneumonitis or interstitial lung disease (e.g., idiopathic pulmonary fibrosis) or pneumonia in past month 8. Has known HIV or active Hepatitis B (e.g., HBV detected by PCR, presence of HBsAg surface antigen and/or Anti-HBc core antigen) or active Hepatitis C (e.g., HCV RNA [qualitative] is detected). Presence of Anti-HBs alone suggesting immunity to Hepatis B is eligible.
9. Any serious known immediate or delayed hypersensitivity reaction(s) to dupilumab and or cemiplimab.
10. Concurrent medical condition requiring the use of systemic immunosuppressive medications, or systemic corticosteroids at doses of greater than 10 mg Prednisone-equivalent. Topical steroids and other localized corticosteroids are permitted. Patients who have received acute, low-dose, systemic immunosuppressant medications equivalent to ≤ 10mg of prednisone within the 7 days prior to study entry (small dose of dexamethasone for nausea, short course for upper respiratory tract infection etc.) may be enrolled in the study. Use of steroids as prophylactic treatment for subjects with contrast allergies to diagnostic imaging contrast dyes will be permitted.
11. Concurrent use or planned use of any forbidden medications within 4 weeks prior to study drug administration, which include chemotherapy, immunotherapy (tumor vaccine, cytokine, or growth factor given to control cancers), other biologic therapy, investigational therapy, or hormonal therapy.
12. Confirmed pregnancy (by pregnancy test) if patient is of childbearing age or breast feeding.
13. Subjects with signs/symptoms suggestive of COVID-19 and confirmed positive COVID-19 test.
14. Eastern Cooperative Oncology Group (ECOG) performance status ≥3 (see Appendix) 15. Any underlying medical condition that, in the Principal Investigator's opinion, will make the administration of study drug hazardous or obscure the interpretation of toxicity determination or adverse events, or renders the patient ineligible to be on study.
