Studien-Rationale

Primary outcome:

1. Pathological Complete Response (pCR) Rate Using the Definition of ypT0/Tis ypN0 (Time Frame - Up to approximately 7 months (Time of surgery)):
The pCR rate (ypT0/Tis ypN0) is defined as the percentage of participants without residual invasive cancer on hematoxylin and eosin evaluation of the complete resected breast specimen and all sampled regional lymph nodes following completion of neoadjuvant systemic therapy by American Joint Committee on Cancer (AJCC) staging criteria (7th edition) assessed by the local pathologist at the time of definitive surgery. The percentage of participants with a pathological Complete Response (pCR) using the definition of (ypT0/Tis ypN0) will be presented for pembrolizumab versus placebo, both in combination with the protocol-specified neoadjuvant anticancer therapies.

2. Event-Free Survival (EFS) (Time Frame - Up to approximately 12 years):
EFS is defined as the time from randomization to disease progression that: precludes definitive surgery, results in a local or distant recurrence, results in a second primary malignancy, or death due to any cause whichever occurs first. The EFS following administration of pembrolizumab and placebo, both in combination with the protocol-specified neoadjuvant and adjuvant anticancer therapies, as determined by the investigator will be presented.

Secondary outcome:

1. Overall Survival (OS) (Time Frame - Up to approximately 12 years):
OS is defined as the time from date of randomization to date of death due to any cause. The OS following administration of pembrolizumab and placebo, both in combination with the protocol-specified neoadjuvant and adjuvant anticancer therapies will be presented.

2. pCR Rate Using the Definition of ypT0ypN0 (Time Frame - Up to approximately 7 months (Time of surgery)):
pCR rate (ypT0ypN0) is defined as the percentage of participants without residual invasive or in situ cancer on hematoxylin and eosin evaluation of the complete resected breast specimen and all sampled regional lymph nodes after completion of neoadjuvant systemic therapy by AJCC staging criteria (7th edition) assessed by the local pathologist at the time of definitive surgery. The percentage of participants with a pCR using the definition of (ypT0ypN0) will be presented for pembrolizumab versus placebo, both in combination with the protocol-specified neoadjuvant anticancer therapies.

3. pCR Rate Using the Definition of ypT0/Tis (Time Frame - Up to approximately 7 months (Time of surgery)):
pCR rate (ypT0/Tis) is defined as the percentage of participants without residual invasive cancer on hematoxylin and eosin evaluation of the complete resected breast specimen (independent of lymph node involvement) after completion of neoadjuvant systemic therapy by AJCC staging criteria (7th edition) assessed by the local pathologist at the time of definitive surgery. The percentage of participants with a pCR using the definition of ypT0/Tis will be presented for pembrolizumab versus placebo, both in combination with the protocol-specified neoadjuvant anticancer therapies.

4. pCR Rate Using the Definitions of ypT0/Tis ypN0, ypT0/Tis, and ypT0 ypN0 in Participants With a Combined Positive Score [CPS] ≥1 (Time Frame - Up to approximately 7 months (Time of surgery)):
pCR rates were calculated using the definitions of ypT0/Tis ypN0, ypT0/Tis, and ypT0 ypN0 after completion of neoadjuvant systemic therapy by AJCC staging criteria (7th edition) assessed by the local pathologist at the time of definitive surgery. The percentage of participants with a pCR using the three definitions of ypT0/Tis ypN0, ypT0/Tis, and ypT0 ypN0 in participants with a CPS ≥1 (with a positive Programmed Cell Death-Ligand 1 [PD-L1] tumor status) will be presented for pembrolizumab versus placebo, both in combination with the protocol-specified neoadjuvant anticancer therapies.

5. EFS in Participants With a CPS ≥1 (Time Frame - Up to approximately 12 years):
EFS is defined as the time from randomization to disease progression that: precludes definitive surgery, results in a local or distant recurrence, results in a second primary malignancy, or death due to any cause whichever occurs first. The EFS following administration of pembrolizumab and placebo, both in combination with the protocol-specified neoadjuvant and adjuvant anticancer therapies, as determined by the investigator for participants with a CPS ≥1 will be presented.

6. OS in Participants With a CPS ≥1 (Time Frame - Up to approximately 12 years):
OS is defined as the time from date of randomization to date of death due to any cause. The OS following administration of pembrolizumab and placebo, both in combination with the protocol-specified neoadjuvant and adjuvant anticancer therapies for participants with a CPS ≥1 will be presented.

7. Number of Participants Experiencing an Adverse Event (AE) (Time Frame - Up to approximately 15 months):
An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experience an AE while receiving pembrolizumab or placebo (including 1 month of safety follow up) will be presented.

8. Number of Participants Experiencing a Serious Adverse Event (SAE) (Time Frame - Up to approximately 17 months):

The number of participants who experience an SAE while receiving pembrolizumab or placebo (including 3 months of safety follow up) will be presented.

9. Number of Participants Experiencing an Immune-related AE (irAE) (Time Frame - Up to approximately 15 months):
Some AEs that may occur in this study that are known to be related to pembrolizumab immunotherapy treatment and may include: pneumonitis, diarrhea/colitis, aspartate aminotransferase/alanine aminotransferase (AST/ALT) elevation or increased bilirubin, Type 1 diabetes mellitus or hyperglycemia, hypophysitis, hyperthyroidism, hypothyroidism, nephritis and renal dysfunction, and myocarditis. The number of participants who experience an irAE while receiving pembrolizumab or placebo (including 1 month of safety follow up) will be presented.

11. Change from Baseline in European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life (QoL) Questionnaire Core 30 (QLQ-C30) Score (Time Frame - Baseline (Cycle 1 Day 1 in Treatment 1) and Cycles 1 and 4 Day 1 in Treatment 2 (Up to approximately 5 months) Each cycle is 21 days.):
The EORTC QLQ-C30 is a 30-item questionnaire developed to assess the quality of life of cancer patients. Individual responses for each of 28 items are given on a 4-point scale (1=Not at All to 4=Very Much), with a lower score indicating a better outcome, and responses for each of 2 items (overall health and overall quality of life) are given on a 7-point scale (1=Very poor to 7=Excellent), with a higher score indicating a better outcome.
