简要总结
Multicenter, double-blind, placebo-controlled, randomized trial.
Patients affected by STAT3 positive newly diagnosed glioblastoma will be eligible. Patients are randomized using a stratified block randomization method with a 1:1 ratio in two arms:
• Experimental/Control arm: Concomitant radiotherapy (60 gy in 30 fractions) + temozolomide 75mg/mq + silibinin/placebo 2 sachets/day dissolved in water throughout concomitant treatment followed by temozolomide cp, 150 mg/m2-200mg/m2, g1-5 q28d + silibinin/placebo 2 sachets/day dissolved in water, day 1-28, q28d for 6-12 cycles. Silibinin/Placebo may be continued until disease progression at the discretion of the physician.
Patients will be stratified based on:
- Type of surgery (complete Vs partial)
- MGMT methylation status (methylated Vs non-methylated)
- ECOG PS (0-1 Vs 2)

入选标准
- •New histologically confirmed diagnosis of glioblastoma (WHO 2021)

- •Signing of informed consent prior to any study procedure
- •Patients (both males and females) should employ adequate contraceptive measures, which should be maintained during the whole duration of the trial (from screening to 6 months after the last dose of Temozolomide).
- •Have adequate bone marrow, liver and kidney function, as measured by the following laboratory assessments conducted within 10 days before the start of study treatment:
- •Hemoglobin > 9.0 g/dl
- •Absolute neutrophil count (ANC) ≥1500/mm3 without granulocyte colony-stimulating factor (G-CSF) and other hematopoietic growth factors

- •ALT and AST <3 x the upper limit of normal
- •Serum creatinine <1.5 times the upper limit of normal
- •Glomerular filtration rate ≥ 30 mL/min/1.73 m2 according to the abbreviated formula Modified Diet in Renal Disease
- •Alkaline phosphatase <2.5 x ULN
- •PT-INR/PTT <1.5 x upper limit of normal (patients who are therapeutically anticoagulated with anticoagulant drugs will be able to participate provided there is no history of abnormal background in these parameters, based on history).

Screening for such chronic conditions is not required by the protocol; bone marrow reserve or organ dysfunction as demonstrated by laboratory tests.

- •Congestive heart failure classified as New York Heart Association (NYHA) Class 2 or higher; Unstable angina (symptoms of angina at rest) or new onset angina ≤3 months prior to screening; myocardial infarction <6 months prior to 'start of study treatment; cardiac arrhythmias requiring antiarrhythmic therapy, with the exception of beta-blockers or digoxin; uncontrolled hypertension (systolic blood pressure [SBP]>140 mmHg or diastolic blood pressure [DBP] >90 mmHg) despite optimal medical management.
- •Arterial thrombotic or embolic events such as stroke and/or transient ischemic attacks) or
- •Pulmonary embolism in the 6 months prior to the start of study treatment
- •Ongoing infection with grade 2 or higher severity (NCI-CTCAE v 5.0)
- •Known history of human immunodeficiency virus (HIV) infection; hepatitis B or C active or chronic requiring treatment with antiviral therapy
- •History of organ allotransplantation
- •Evidence or history of any bleeding diathesis (including mild hemophilia), regardless of its severity;
- •Injuries, ulcers or bone fractures that have not fully resolved.
- •Renal failure requiring hemodialysis or peritoneal dialysis
- •Presenting interstitial lung disease with ongoing signs and symptoms at the time informed consent is obtained.

结局指标
主要结局
Progression Free Survival (PFS)
时间窗: Through study completion, an average of 2 years
Evaluation of Progression Free Survival (PFS) in patients with newly diagnosed IDH wild-type and STAT3-positive glioblastoma using silibinin 2 sachets per day (1g/day), during chemoradiotherapy and maintenance treatment with temozolomide, compared with placebo. The progression free survival (PFS) will be determined as the time from the date of randomization to the date of disease progression determined using RANO 2.0 criteria or to the date of death, whichever occurs first. Patients without a PFS event at the time of analysis will be censored at the date of last assessment.
