Cryoablation Combined With Tirelizumab and Bevacizumab in Liver Metastatic TNBC Patients Failed by Multiline Therapy (Castle06(BC))

June 6, 2022 updated by: Zhimin Shao, Fudan University

A Phase II Clinical Study of Cryoablation Combined With Tirelizumab and Bevacizumab in Liver Metastatic Triple Negative Breast Cancer Patients Failed by Multiline Therapy

This is a Phase II, open-label study evaluating the efficacy and safety of Cryoablation combined with Tirelizumab and Bevacizumab in liver metastatic triple-negative breast cancer patients failed by multiline therapy.

Study Overview

Detailed Description

This is a prospective, single-arm, single-center phase II clinical trial in liver metastatic triple-negative breast cancer patients failed by multiline therapy.

All subjects will receive cryoablation combined with tirelizumab + bevacizumab:

  1. Cryoablation of liver metastases: Cryoablation of 1-2 typical metastatic lesions will be performed on D1 under general anesthesia and ultrasound guidance for two cycles. If the patient has no measurable lesions outside the liver, the measurable lesions should be retained after partial ablation of the liver lesions.
  2. PD-1 antibody + anti vascular therapy: patients will receive 200mg Tirelizumab ( IV Q3W) + Bevacizumab 7.5mg/kg ( IV Q3W) at D14 after cryoablation until there is disease progression, intolerable toxic reaction, subject withdraws informed consent or the study ends (whichever comes first).
  3. Puncture biopsy of liver metastases will completed 1-3 days before cryoablation, 1-3 days before the first treatment with tirelizumab + bevacizumab, 2 cycles after treatment with tirelizumab + bevacizumab and after disease progression, and blood samples (about 10ml) were collected for mutation load detection and immune function evaluation.

Description

Inclusion Criteria:

  • Histologically or Imageologically confirmed liver metastatic tnbc patients;
  • Histologically confirmed diagnosis of TNBC characterized by estrogen receptor negative (ER-), progesterone receptor negative (PR-) and human epidermal growth factor-2 receptor negative (HER2-);
  • ≥ 2 prior lines systemic therapy;
  • Measurable disease according to Response Evaluation Criteria in Solid Tumors v1.1 (RECIST v1.1);
  • The patients show no signs of bile duct obstruction, and the bilirubin is below the upper limit of 1.5x normal value (ULN);
  • Age ≥ 18 years on the day of signing the ICF (or the legal age of consent in the jurisdiction in which the study is taking place);
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1;
  • The functions of the patient's organs and blood system meet the requirements;
  • Blood system function: absolute neutrophil count (ANC) ≥ 1.5 x 109 / L, platelet count ≥ 100 x 109 / L
  • Renal function: estimated glomerular filtration rate or creatinine clearance > 50 ml / min / 1.73 M2
  • Liver function: total bilirubin ≤ 1.5 x ULN, AST and alt ≤ 5 x ULN
  • Estimated survival time ≥12 weeks.

Exclusion Criteria:

  • The patient is currently receiving or has received irradiation or local treatment for the target lesion in the past 3 weeks.
  • The patient had previously received cryoablation.
  • The patient received major surgery within 14 days before enrolling in the study.
  • Palliative radiotherapy must be completed at least 2 weeks before enrolling in the study, and there is no plan for additional radiotherapy for the same lesion; ·Patients whose AE caused by radiotherapy did not recover to ≤ CTCAE 1 degree
  • The patient had metastatic brain lesions, including asymptomatic and well controlled lesions.
  • Complicated with infection and requiring intravenous antibiotic treatment.
  • The patient has any clinically significant disease or history that the investigator believes may endanger the safety of the patient or the reliability of the study results.
  • The patient has a history of any other malignancy unless the remission period exceeds 1 year. (do not exclude skin cancer, cervical cancer in situ, superficial bladder cancer, and breast cancer in radical treatment).
  • Female patients are pregnant or breastfeeding.
  • The patient received any trial drug within 14 days before receiving the first study drug.
  • The patient had undiminished or unstable severe toxicity (≥ CTCAE 4.0 grade 2) after previous use of another trial drug and / or previous cancer treatment, except anemia, weakness and hair loss.
