简要总结
This is an open-label, single-arm, phase II clinical trial to explore the efficacy and safety of low-dose radiotherapy combined with programmed death 1 (PD-1) inhibitor (sintilimab) and temozolomide in recurrent glioblastoma. The eligible patients are scheduled to administered sintilimab 200mg D1 Q3W temozolomide 50mg/m2 QD and radiotherapy 1Gy/1F D1/D2/D8/D15 Q3W for 4-6 cycles, then sintilimab for maintenance. The overall primary study hypothesis is that the combination regimen of low-dose radiotherapy, sintilimab and temozolomide is safe and feasible in the treatment of recurrent glioblastoma.

入选标准
- •Histologically confirmed glioblastoma, radiographically or pathologically diagnosed recurrence.
- •Aged ≥ 18 years.
- •≥12 weeks after postoperative radiotherapy.
- •Karnofsky performance status (KPS) ≥
- •Expected survival > 3 months.
- •Adequate organ function, based on meeting all of the following criteria (no blood components and cytologic growth factors were received within 14 days prior to the test):
- •Hemoglobin ≥ 90 g/L; absolute neutrophil count ≥ 1.5 × 10^9/L; and platelet count ≥ 100 × 10^9/L;
- •Serum albumin ≥ 28 g/L;
- •Total bilirubin ≤ 1.5 × upper limit of normal (ULN); Alanine transaminase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN;
- •Serum creatinine ≤ 1.5 × ULN;
- •Activated partial clotting enzyme time and international standardized ratio (INR) ≤ 1.5 × ULN (Patients on stable doses of anticoagulant therapy such as low molecular weight heparin or warfarin with INR within the expected treatment range of anticoagulants can be screened ).
- •Thyroid stimulating hormone ≤ ULN; If abnormal, T3 and T4 levels should be examined, and if T3 and T4 levels are normal, they can be screened.
- •Subjects voluntarily join the study and sign an informed consent form, with good compliance.
排除标准
- •Treatment with a dose of prednisone > 10mg /d or equivalent dose of corticosteroids is required.
- •There exist other uncontrolled central nervous system diseases unrelated to cancer.
- •A history of other malignant tumors within the previous 5 years or at the time of enrollment, except for cured skin basal cell carcinoma and cervical in situ cancer, as well as thyroid papilloma.
- •Uncontrolled cardiac clinical symptoms or diseases, such as New York Heart Association (NYHA) class II or above heart failure, unstable angina pectoris, myocardial infarction within 1 year, patients with clinically significant supraventricular or ventricular arrhythmia requiring clinical intervention.
- •Serious infections, such as severe pneumonia, bacteremia, and infection comorbidities requiring hospitalization, occurred within 4 weeks.
- •Active autoimmune diseases, such as interstitial pneumonia, colitis, hepatitis, hypophysitis, vasculitis, nephritis, hyperthyroidism, hypothyroidism; It does not include patients with vitiligo or childhood asthma/allergies that have healed and require no intervention as adults.
- •A history of immunodeficiency, including HIV-positive status or other acquired congenital immunodeficiency diseases, or a history of organ transplantation and bone marrow transplantation.
- •Patients with active tuberculosis infection found by history or CT examination, or patients with active tuberculosis infection history within 1 year prior to enrollment, or patients with active tuberculosis infection history before 1 year without formal treatment.
