Study of N-803, PD-L1 t-haNK, and Bevacizumab for Recurrent Glioblastoma

This study is testing a combination of treatments for glioblastoma (a type of brain cancer) that has come back or gotten worse. The treatments being studied are N-803, PD-L1 t-haNK, and Bevacizumab, sometimes also with Tumor Treating Fields (TTFields, a device that uses electrical fields). Researchers want to see how safe these treatments are and how well they work. You might be able to join if you are 18 or older and have glioblastoma that has progressed after other treatments. The study will look at side effects and changes in your blood tests to see if the treatments are successful. The current status of this study is unclear, and it plans to enroll 34 participants.

Study design
This study has two parts. The first part is a single-arm study where everyone gets the same combination of treatments. The second part is a randomized study, meaning participants will be assigned to one of two treatment groups. This study is open-label, so you and your doctors will know which treatments you are receiving.
What's involved
If you join, you will receive treatments intravenously (IV, into a vein) or subcutaneously (SC, under the skin) every two weeks, on Day 1 and Day 15 of each 28-day cycle. You may also use the TTFields device. Treatment can last for up to 76 weeks (19 cycles). Blood tests will be taken at the start, during each cycle, and at the end of treatment.
Compensation
Not stated in the trial record.
Follow-up
Your health will be monitored for side effects for 30 days after your last treatment study visit.

  • Incidence of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs)From beginning of Cycle 1 (each cycle is 28 days) to 30 days after end of treatment study visit.

    TEAEs and SAEs graded using the NCI CTCAE v5.0

  • Incidence of clinically significant changes in comprehensive metabolic panel (CMP)From baseline, pre-intervention, Cycle 1 (each cycle is 28 days) and each subsequent treatment Cycle on Days 1 and Day 15 and at the end of treatment study visit.

    Standard blood chemistry panel made up of 14 separate chemistry measurements so can detect a range of abnormalities in blood sugar, nutrient balance, and liver and kidney health. Each clinical site will use their local laboratory upper limit of normal (ULN) range. The treating investigator will assess each result composing the CMP and determine if each result is within expected normal range or outside of the expected normal range.

  • Incidence of clinically significant changes in Hematology blood panel.From baseline, pre-intervention, Cycle 1 (each cycle is 28 days) and each subsequent treatment Cycle on Days 1 and Day 15 and at the end of treatment study visit.

    Blood test checking the levels for White Blood Cell, Red Blood Cell, Platelets, Hemoglobin, Hematocrit, Basophils, Eosinophils, Lymphocytes, Monocytes and Neutrophils per unit volume. Each clinical site will use their local laboratory upper limit of normal (ULN) range. The treating investigator will assess each component of the Hematology panel and determine if each result is within expected normal range or outside of the expected normal range.

  • Incidence of clinically significant changes in Urinalysis.From baseline, pre-intervention, Cycle 1 (each cycle is 28 days) and each subsequent treatment Cycle on Days 1 and Day 15 and at the end of treatment study visit.

    Checking the appearance, concentration and content of urine for any abnormalities. Each clinical site will use their local laboratory upper normal limit (UNL) range. The treating investigator will assess each component of the urinalysis and determine if each result is within expected normal range or outside of the expected normal range.

  • 12-lead Electrocardiogram (ECG)From baseline, pre-intervention, Cycle 1 (each cycle is 28 days) and each subsequent Cycle Day1 through to the end of treatment study visit.

    Perform 12-lead ECG as safety monitoring measurement. The parameters to be assessed for each one are the following: QT Interval, QTc Interval, QTcB Interval, QTcF Interval, PR Interval, QRS Duration and RR Interval with the unit in msec.

  • Incidence of clinically significant changes in TemperatureFrom baseline, pre-intervention, Cycle 1 (each cycle is 28 days) and Cycle 2 on days 1, 2 and 15, followed by each subsequent treatment Cycle on Days 1 and 15 and on the end of treatment study visit.

    Temperature measured in either Fahrenheit or Celsius and for any abnormalities. Each site will assess to determine if temperature is within expected normal range or outside of the expected normal range.

  • Incidence of clinically significant changes in Heart RateFrom baseline, pre-intervention, Cycle 1 (each cycle is 28 days) and Cycle 2 on days 1, 2 and 15, followed by each subsequent treatment Cycle on Days 1 and 15 and on the end of treatment study visit.

    Heart rate measured in beats/minute. Each site will assess to determine if heart rate is within expected normal range or outside of the expected normal range.

  • Incidence of clinically significant changes in Respiratory RateFrom baseline, pre-intervention, Cycle 1 (each cycle is 28 days) and Cycle 2 on days 1, 2 and 15, followed by each subsequent treatment Cycle on Days 1 and 15 and on the end of treatment study visit.

    A pulse oximeter measures oxygen saturation as a percentage. Determines the ratio of the current levels of oxygenated hemoglobin to deoxygenated hemoglobin. Each site will assess to determine if oxygen saturation is within expected normal range or outside of the expected normal range.
