Neoadjuvant Her2-targeted Therapy and Immunotherapy With Pembrolizumab (neoHIP)

A phase 2 open-label, randomized, multi-center trial to evaluate the efficacy and safety of neoadjuvant trastuzumab, pertuzumab and weekly paclitaxel as compared to neoadjuvant trastuzumab, pertuzumab, pembrolizumab and weekly paclitaxel, or neoadjuvant trastuzumab, pembrolizumab and weekly paclitaxel in chemo naive patients with invasive HER2 positive breast cancer whose primary tumors are > 2 cm and/or clinically lymph node positive.

Inclusion Criteria:
• Male/female patients with histologically confirmed invasive HER2-positive (by ASCO/CAP guidelines) unilateral breast cancer
• Have previously untreated non-metastaic (M0), cT2-4N0 or cT1-4N1-3 (biopsies of clinically suspicious lymph nodes to confirm nodal status is encouraged).
• Multifocal/centric disease is permitted if all suspicious foci have been biopsied and are consistent with HER2-positive (by ASCO/CAP guidelines) invasive breast cancer
• Have adequate organ function as defined by the following parameters. Specimens must be collected within 10 days prior to the start of study treatment.
• Renal Creatinine (≤1.5 × ULN OR) OR Measured or calculated(b) creatinine clearance (≥30 mL/min for participant with creatinine levels) (GFR can also be used in place of creatinine or CrCl) (>1.5 × institutional ULN)
• Hepatic Total bilirubin ≤1.5 ×ULN OR direct bilirubin ≤ULN for participants with total bilirubin levels >1.5 × ULN AST (SGOT) and ALT (SGPT) ≤2.5 × ULN (≤5 × ULN for participants with liver metastases)
• Coagulation International normalized ratio (INR) OR prothrombin time (PT) Activated partial thromboplastin time (aPTT) ≤1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants
• Cardiac Echocardiogram or MUGA Baseline LVEF ≥ 55%

Exclusion Criteria:
• Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g., CTLA-4, OX 40, CD137).
• Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to randomization.
Note: If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment.
• Has received prior radiotherapy within 2 weeks of start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis.
• Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment.
Note: Participants who have entered the follow-up phase of an investigational study may participate as long as it has been 4 weeks after the last dose of the previous investigational agent.
• Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
• Has a known additional malignancy that is progressing or has required active treatment within the past 3 years. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g. breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded.
• Has an active infection requiring systemic therapy.
• Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the subject's participation for the full duration of the study, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
