  • Allergies and adverse drug reaction (history of allergy or hypersensitivity to study drug components, contraindications to any of the study drugs of the chemotherapy regimen)
  • Other exclusion criteria: Prisoners or participants who are involuntarily incarcerated, participants who are compulsorily detained for treatment of either a psychiatric or physical (i.e. infectious disease) illness
  • White blood cells < 2000/μL (SI: < 2.00 × 109/L)
  • Neutrophils < 1500/μL (SI: < 1.50 × 109/L)
  • Platelets < 100 × 103/μL (SI: < 100 × 109/L) (transfusions not permitted within 72 h prior to qualifying laboratory value)

TnT or TnI levels between > 1 to 2 × ULN will be permitted to participate in the study if a repeat assessment remains 2 × ULN and participant undergoes a cardiac evaluation. When repeat levels within 24 h are not available, a repeat test should be conducted as soon as possible.

Primary Outcome Measures
NameTimeMethod
Incidence of treatment-emergent adverse events (safety and tolerability)20 weeks

Incidence of treatment-emergent adverse events will be assessed according to the latest "Clavien- Dindo Classification of surgical complications" and Common Terminology Criteria of Adverse Events (CTCAE).

Secondary Outcome Measures
NameTimeMethod
Radiographic therapy response between pre-and post-neoadjuvant treatment20 weeks

Radiographic therapy response will be determined by magnetic resonance imaging-assessed tumor regression grade (mrTRG)

Pathologic therapy response to neoadjuvant treatment20 weeks

Pathological therapy response will be determined according to the latest American Joint Committee on Cancer/International Union Against Cancer-Tumor Node Metastasis (AJCC/UICC-TNM) staging and tumor regression grade (TRG).
