Brief Summary:
A phase 2 open-label, randomized, multi-center trial to evaluate the efficacy and safety of neoadjuvant trastuzumab, pertuzumab and weekly paclitaxel (THP) as compared to neoadjuvant trastuzumab, pertuzumab, pembrolizumab and weekly paclitaxel (THP-K), or neoadjuvant trastuzumab, pembrolizumab and weekly paclitaxel (TH-K) in chemo naive patients with invasive human epidermal growth factor receptor 2 (HER2) positive breast cancer whose primary tumors are > 2 cm and/or clinically lymph node positive. Treatment will be followed by standard of care breast surgery and physician's choice adjuvant therapy per standard of care.

Detailed Description:

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

Patients will be randomized to either Arm A: THP (trastuzumab, pertuzumab and weekly paclitaxel), Arm B: THP-K (trastuzumab, pertuzumab, pembrolizumab and weekly paclitaxel) or Arm C: TH-K (trastuzumab, pembrolizumab and weekly paclitaxel). Patients will be stratified according to hormone receptor status and lymph node status. All patients will be treated weekly every three weeks for four cycles (only paclitaxel will be administered weekly) and then undergo breast surgery. Arm A patients will be regarded as the reference group.

    Mean difference in time (in months) from date of surgery (date of no disease) to the first documentation of invasive progressive disease or death.

    Mean difference in time (in months) from randomization to death.

  8. Symptomatic cardiac events and asymptomatic LVEF events [ Time Frame: 36 months from randomization ]
    Incidence of symptomatic cardiac events and asymptomatic left ventricular ejection fraction (LVEF) events (LVEF < 50% or a decrease ≥ 10 ejection fraction points from baseline).

    Incidence and severity of adverse events (AE) and serious adverse events (SAE) from cycle 1 day 1 until 30 days post-surgery.
