Irinotecan Liposomes Combined With Bevacizumab in the Treatment of Recurrent Glioma

Exploratory Study of Irinotecan Liposomes Combined With Bevacizumab in the Treatment of Progressive or Recurrent Glioma

With the optimization of the dosage form of irinotecan, the replacement of ordinary irinotecan with irinotecan liposomes should improve the safety and the expected efficacy. Therefore, an exploratory study on the treatment progress of irinotecan liposomes combined with bevacizumab for recurrent brain glioma should be conducted. To evaluate the efficacy and safety of irinotecan liposomes combined with bevacizumab in the treatment of progressive/recurrent brain glioma, so as to provide more treatment options for patients with brain glioma.

This study was to observe the efficacy and safety of irinotecan liposomes combined with bevacizumab in the treatment of progressive/recurrent brain glioma. The study was a single-center, single-arm, prospective study. Patients with progressive/recurrent glioma who met the inclusion criteria and did not meet the exclusion criteria were treated with irinotecan liposome combined with beizumab. The optimal ORR of patients during treatment was mainly evaluated, and the DCR, DoR, PFS, OS, and safety of patients were mainly evaluated.

Inclusion Criteria:

• Age 18-75 years old;
• Patients diagnosed with glioma by histology, patients with progress in first-line therapy, including postoperative recurrence, progress in first-line standard therapy, and patients unable to undergo surgery/radiotherapy;
• no previous treatment with irinotecan or irinotecan liposomes;
• At least one measurable or evaluable lesion according to RANO criteria;
