Systemic and Local Levels of Lidocaine During Surgery for the Removal of Glioblastoma
- Conditions
- Glioblastoma
- Interventions
- Registration Number
- NCT04716699
- Lead Sponsor
- Kiarash Shahlaie, M.D., Ph.D.
- Brief Summary
This clinical trial measures the amount and effect of lidocaine injected into patients with glioblastoma while they are undergoing surgical removal of their brain tumors. Lidocaine is a substance used to relieve pain by blocking signals at the nerve endings in skin. Information gained from this study may help researchers come up with new treatments to help patients with glioblastomas in the future.
- Detailed Description
PRIMARY OBJECTIVE:
I. To assess the pharmacokinetic properties of intravenously administered lidocaine inside a glioblastoma tumor by means of mass spectroscopy.
SECONDARY OBJECTIVE:
I. To assess the differences in overall survival (OS) and progression free survival (PFS) between the patients in the lidocaine therapy group and historical controls taken from the literature (Stupp et al) with comparable post-operative treatment regimen.
OUTLINE:
Patients receive bolus lidocaine intravenously (IV) per standard of care. After intubation, patients receive another infusion of lidocaine IV over 4 hours or until the end of surgery. Patients also undergo collection of blood and tumor samples at the start of surgery and hourly afterwards until a total of 4 samples are collected.
After completion of surgery, patients are followed for 24 hours, and at 7-14 days, up to 30 days.

Group Intervention Description Health services research (lidocaine, surgery) Biospecimen Collection Patients receive bolus lidocaine IV per standard of care. After intubation, patients receive another infusion of lidocaine IV over 4 hours or until the end of surgery. Patients also undergo collection of blood and tumor samples at the start of surgery and hourly afterwards until a total of 4 samples are collected. Health services research (lidocaine, surgery) Resection Patients receive bolus lidocaine IV per standard of care.

- Primary Outcome Measures
Name Time Method Difference between the concentrations of lidocaine in the tumor tissue and in the blood (baseline level) At start of surgery up until completion of surgery, assessed up to 4 hours after starting surgery Analysis is mainly descriptive and will be mainly done by Lidocaine analysis lab. Will report the mean and standard deviation of concentration of lidocaine in the tumor and blood at 3 time points. The pharmacokinetics of lidocaine within the tumor will be summarized using the means, and standard pharmacokinetics parameters will be reported (maximum concentration, time of maximum concentration, and area under the curve). If applicable, will use mixed effects model to summarize trajectories of change for concentration measured at multiple time points, which will account for correlation between repeated measures within patient.
- Secondary Outcome Measures
Name Time Method Progression free survival (PFS) From diagnosis to first documented evidence of disease progression or death, whichever comes first, assessed up to 30 days after surgery Kaplan-Meier plots and confidence intervals will be used to summarize PFS. Medians (and associated 95% confidence intervals) of PFS will then be calculated and compared with historical control from the literature.
Overall survival (OS) From diagnosis to death, assessed up to 30 days after surgery Kaplan-Meier plots and confidence intervals will be used to summarize OS. Medians (and associated 95% confidence intervals) of OS will then be calculated and compared with historical control from the literature.
Incidence of adverse events (AEs) Up to 30 says after surgery Will record safety and toxicity profile using National Cancer Institute Common Terminology Criteria for Adverse Events 5.0. AEs will be summarized using descriptive statistics. The type, grade, frequency and proportion of toxicities will be reported, along with associated 95% confidence interval of proportion.
