A Prospective, Randomized, Controlled Clinical Study on the Prevention of Chemotherapy Related Myelosuppression in Patients with Ewing's Sarcoma Using Trilaciclib

A Prospective, Randomized, Controlled Clinical Study on the Prevention of VDC/IE Chemotherapy Related Myelosuppression in Patients with Ewing's Sarcoma Using Trilaciclib

NCT06699472•Fudan University

View on ClinicalTrials.gov

Summary

This study is a prospective, open label, randomized controlled clinical trial aimed at patients with Ewing's sarcoma who have not received systematic anti-tumor treatment in the past. The aim is to evaluate the efficacy and safety of prophylactic use of Trilaciclib before VDC+IE chemotherapy. Patients with Ewing's sarcoma who have not received systemic anti-tumor therapy in the past will be screened for qualified subjects who meet the inclusion criteria after signing informed consent. Eligible patients will be randomly divided into an experimental group and a control group in a 1:1 ratio. The control group will receive alternating VDC+IE chemotherapy for 3 weeks, a total of 17 cycles, or until disease progression, intolerable adverse reactions, or withdrawal of informed consent occur. The experimental group received VDC+IE alternating chemotherapy combined with Trilaciclib, with 3 weeks as one course of treatment, for a total of 17 cycles or until disease progression, intolerable toxicity, withdrawal of informed consent, initiation of other anti-tumor treatments, death, or other situations specified in the protocol where treatment should be discontinued. Both the control group and the experimental group can receive supportive nursing treatment according to clinical needs.

Inclusion Criteria

•Age ≥ 14 years old and ≤ 40 years old;
•Histologically confirmed Ewing's sarcoma;
•Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score of 0 to 1;
•Have not received any anti-tumor treatment other than surgery in the past;
•Expected survival of more than 3 months;
•Possess sufficient organ and bone marrow function, with laboratory test values meeting the following requirements within 7 days prior to enrollment (no blood components, cell growth factors, albumin, or other corrective treatment drugs are allowed within 14 days prior to obtaining laboratory tests), as follows Blood routine: Absolute neutrophil count (ANC) ≥ 1.5 × 109/L, platelet count (PLT) ≥ 100 × 109/L, hemoglobin (HGB) ≥ 100 g/L (no transfusion or erythropoietin dependence within 14 days) Liver function: serum total bilirubin ≤ 1.25 times the upper limit of normal (ULN); ALT and AST ≤ 2.5 x ULN (≤ 5x ULN for patients with liver metastases); Serum albumin ≥ 30 g/L; Alkaline phosphatase (ALP) ≤ 5 × ULN.
•Renal function: Serum creatinine (Cr) ≤ 1.25 × ULN, or creatinine clearance rate ≥ 60 mL/min (using the standard Cockcroft Gault formula): Urine routine results show urinary protein\<2+; For patients whose baseline urine routine test shows urinary protein ≥ 2+, 24-hour urine collection should be performed with a 24-hour urine protein quantification of\<1g.
•Coagulation function: International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 times ULN; If the subject is receiving anticoagulant therapy, as long as the INR is within the intended range of use of the anticoagulant drug.
•For female subjects of childbearing age, a urine or serum pregnancy test should be conducted 3 days before receiving the first study drug and the result should be negative;
•The subjects and their sexual partners are required to use a medically approved contraceptive measure (such as intrauterine device, contraceptive pill, or condom) during the study treatment period and within 6 months after the end of the study treatment period.

Exclusion Criteria

•Previously received anti-tumor treatment other than surgery and radiation therapy for any malignant tumor;
•Subjects who cannot accept or tolerate this chemotherapy regimen for various reasons;
•Biopsy confirmed a patient with bone marrow infiltration;
•The patient has undergone significant surgical procedures unrelated to Ewing's sarcoma within the 4 weeks prior to enrollment, or has not fully recovered from such surgical procedures;
•Serious heart disease or discomfort, including but not limited to the following diseases:
•Diagnosed history of heart failure or systolic dysfunction (LVEF\<50%); High risk uncontrolled arrhythmias, such as atrial tachycardia, resting heart rate\>100bpm, significant ventricular arrhythmias (such as ventricular tachycardia), or higher-level atrioventricular block (i.e. Mobitz II second or third degree atrioventricular block); Angina requiring treatment with anti angina drugs; Clinically significant heart valve disease; ECG shows transmural myocardial infarction; Poor control of hypertension (systolic blood pressure\>180mmHg and/or diastolic blood pressure\>100mmHg)
•Individuals with a known history of allergies to the components of this medication regimen;
•Breastfeeding female patients, female patients with fertility and positive baseline pregnancy test results, or reproductive age patients who are unwilling to take effective contraceptive measures during the entire trial period and within 7 months after the last study medication;
•The researchers believe that the patient is not suitable to participate in any other circumstances of this study.
