Official title

A Prospective, Randomized, Open-label Phase III Clinical Study of the Efficacy and Safety of Fluzoparib Combined With Adjuvant Endocrine Therapy Versus Adjuvant Endocrine Therapy for HR+/HER2- SNF3-subtype Early Breast Cancer (BCTOP-L-A01)

Overview

This is a prospective, randomized, open-label phase III clinical study on the efficacy and safety of fluzoparib combined with adjuvant endocrine therapy versus adjuvant endocrine therapy for HR+/HER2- SNF3-subtype early breast cancer.

Detailed description

This is a prospective, randomized, open-label phase III clinical study on the efficacy and safety of fluzoparib combined with adjuvant endocrine therapy versus adjuvant endocrine therapy for HR+/HER2- SNF3-subtype early breast cancer.

A total of 766 patients with luminal-type early breast cancer who received surgery at the Fudan University Shanghai Cancer Cancer and were classified as SNF3 (proliferative) by SNF algorithm fusion clustering will be collected for this study. Before enrollment, the primary tumors of the patients were subjected to molecular typing based on H\&E slices combined with digital pathology, and subsequent enrollment could be considered if patient pathology was confirmed as SNF3 subtype.

Interventions

  • Drug Fluzoparib
    Fluzoparib 50mg bid orally for 1 year.
  • Drug Anastrozole
    1mg, qd orally
  • Drug Letrozole
    2.5mg, qd orally
  • Drug Exemestane
    25mg, qd orally
  • Drug Tamoxifen
    10mg, bid orally
  • Drug Toremifene
    60mg, qd orally
  • Drug Abemaciclib
    150mg/100mg/50mg, bid orally for 2 years
  • Drug LHRH agonist

Primary outcome measures

  • invasive disease free survival (iDFS) [Time frame: 5 years]
Secondary outcome measures (4)
  • distant relapse free survival (DRFS) [Time frame: 5 years]
  • overall survival (OS) [Time frame: 5 years]
  • Adverse Effects [Time frame: 5 years]
  • Number of participants with Patient Reported Outcome (PRO) [Time frame: 5 years]

Eligibility criteria

Inclusion criteria

If IHC is 2+, a negative in situ hybridization (Fluorescence in situ hybridization (FISH), Chromogenic in situ hybridization (CISH) , or Silver in situ hybridization (SISH)) test is required by local laboratory testing.); definition of SNF3 subtype: SNF3 subtype confirmed by digital pathology of H\&E sections;
  • Postoperative pathological stage T2-4N0-3M0;

  • Time of randomization from surgery does not exceed 16 months;
  • Time of endocrine therapy from last non-endocrine anti-tumor treatment does not exceed 12 weeks;
  • Has adequate organ function meeting the following criteria: (1) adequate bone marrow function: hemoglobin ≥ 90 g/L (no blood transfusion within 14 days); absolute neutrophil count ≥ 1.5 x 10\^9 /L; platelet count ≥ 100 \* 10\^9 /L; (2)adequate liver and kidney function: Alanine Aminotransferase (ALT) ≤ 3×upper limit of normal (ULN), Aspartate Aminotransferase (AST) ≤ 3×ULN, Total Bilirubin (TBIL)≤ 1.5×ULN, serum creatinine ≤ 1×ULN,and with endogenous creatinine clearance rate of >50 ml/min (Cockcroft-Gault formula);
  • Patients receiving radiotherapy must recover from the acute phase reaction of radiotherapy, with a washout period of at least 14 days from the end of radiotherapy to randomization;
  • Patients who received chemotherapy in the early stage must recover from acute adverse reactions to chemotherapy (\[CTCAE\] grade ≤ 1) before randomization, except for hair loss or grade 2 peripheral neuropathy. There is a washout period of at least 21 days from the last chemotherapy administration to randomization (assuming the patient has not received radiotherapy);
  • Patients can take medication orally on their own;
