A Study of Temodar With PCI-24781 for Patients With Recurrent Glioma
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to learn about treatment for a type of brain cancer called glioma. This clinical trial is for people with glioma who have been cancer-free for a period of time but their cancer has come back. The primary goals of this clinical trial are the following:
-
To determine the recommended dose of PCI-24781 with metronomic temozolomide
-
To evaluate side effects associated with using PCI-24781 with metronomic temozolomide
| Condition or Disease | Intervention/Treatment | Phase |

Phase 1 |
Detailed Description
Patients will be enrolled to each dose level in cohorts of 3. Dose level escalation/de-escalation will follow BOIN (Bayesian Optimal Interval) design rules based on analysis of dose-limiting toxicities (DLTs) that occur within the first two cycles of protocol treatment. Protocol treatment will continue until disease progression or intolerable toxicity.
Dose Levels:
-
Dose Level 1: 60 mg PCI-24781 BID (two times daily)
-
Dose Level 2: 100 mg PCI-24781 BID
-
Dose Level 3: 140 mg PCI-24781 BID
Primary Objectives
- To evaluate the toxicities and determine the recommended dose of PCI-24781 with metronomic temozolomide in subjects with recurrent high grade glioma, [grade III or IV glioma (glioblastoma, gliosarcoma, anaplastic astrocytoma, anaplastic oligodendroglioma)].
Secondary Objectives
-
To evaluate changes in the acetylation of peripheral blood mononuclear cell (PBMC) histones H3 and H4 during treatment II. To evaluate for acetylation of histones H3 and H4 using peripheral blood exosomes III. To evaluate progression-free and overall survival of subjects with recurrent high grade glioma treated with therapy with PCI-24781 with metronomic temozolomide. Subjects with stable or responsive disease after every 2 cycles will continue on therapy until intolerance or progressive disease.
-
To descriptively examine quality of life (QOL) using EORTC QLQ-C30, QLQ-BN20 during treatment.
-
To characterize the pharmacokinetics (PK) of PCI-24781, temozolomide, and the combination of the 2 drugs.
-
To measure tumor response. VII. To correlate molecular profiles with tumor response.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Single arm Patients will receive a combination of PCI-24781 and temozolomide. Patients will receive a loading dose of PCI-24781 prior to the start of Cycle 1; patients will take PCI-24781 by mouth twice a day starting 7 days prior to Cycle 1, Day 1 and ending 4 days prior to Cycle 1, Day 1. Patients will continue taking PCI-24781 on days 1-4, 8-11, 15-18, and 22-25 of each 28 day cycle, starting with Cycle 1, Day 1. The initial dose level is 60 mg of PCI-24781 by mouth twice daily. The dose level may be escalated based on results of interim data analysis. Patients will additionally initiate metronomic temozolomide on Cycle 1, Day 1 at a dose of 50 mg/m2, taken by mouth twice daily. Patients will continue the PCI-24781 and metronomic temozolomide regimen until disease progression or intolerance. |

Outcome Measures
Primary Outcome Measures
- Evaluation of toxicities associated with PCI-24781 and metronomic temozolomide therapy [Up to 25 months]
The incidence of adverse events (AEs) and serious adverse events (SAEs) will be described for each dose level cohort. Toxicities will be assessed using the Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Toxicities will be graded on a scale ranging from 1 to 5, with higher numbers indicating a higher severity grade.
- Evaluation of toxicities associated with PCI-24781 and metronomic temozolomide therapy [Up to 25 months]
The frequency of the occurrence of overall toxicity will be categorized by toxicity grades. Toxicity will be assessed using the Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Toxicities will be graded on a scale ranging from 1 to 5, with higher numbers indicating a higher severity grade.
- Determine the recommended dose of PCI-24781 [Up to 20 months]
Patients who complete the first two cycles of treatment or patients experiencing a dose-limiting toxicity (DLT) within the first two cycles of treatment will be considered evaluable. The target DLT rate for the maximum tolerated dose (MTD) is 0.25. If the observed DLT rate at the current dose is ≤ 0.197, escalate the dose to the next higher dose level If the observed DLT rate at the current dose is > 0.298, de-escalate the dose to the next lower dose level Otherwise, stay at the current dose level The MTD determination will be based on isotonic regression. The MTD will be defined as the dose for which the isotonic estimate of the DLT rate is closest to the target DLT rate of 0.25. If a tie exists between potential doses the higher dose level will be selected when the isotonic estimate is lower than the target DLT rate and the lower dose level will be selected when the isotonic estimate is greater than or equal to the target DLT rate.
Secondary Outcome Measures
- Evaluation of changes in the acetylation of peripheral blood mononuclear cell (PBMC) histones H3 and H4 during treatment [Up to 20 months]
Peripheral blood samples collected at baseline and during treatment will be analyzed for changes over time.
- Evaluation of acetylation of histones H3 and H4 using peripheral blood exosomes [Up to 20 months]
Peripheral blood samples collected at baseline and during treatment will be analyzed.
- Evaluation of progression-free survival (PFS) [36 months]
PFS will be estimated using the Kaplan-Meier method. PFS is defined as the time from treatment initiation to disease progression.
- Evaluation of overall survival (OS) [36 months]
OS will be estimated using the Kaplan-Meier method. OS is defined as the time from treatment initiation to death from any cause.
- Descriptive examination of patient quality of life (QOL) during treatment [24 months]
Patient QOL will be measured throughout treatment using the EORTC QLQ-C30 (European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire). Patients respond using a scale that ranges from 1 to 4, with 1 meaning "Not at All" and 4 meaning "Quite a Bit." The final two questions ask patients to rate their overall health and quality of life using a scale ranging from 1 to 7, where higher numbers indicate more favorable outcomes.
- Descriptive examination of patient quality of life (QOL) during treatment [24 months]
Patient QOL will be measured throughout treatment using the EORTC QLQ-BN20 (European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire). Patients respond using a scale that ranges from 1 to 4, with 1 meaning "Not at All" and 4 meaning "Quite a Bit."
- Measurement of tumor response [Up to 36 months]
Overall response will be assessed using Response Assessment in Neuro-Oncology (RANO) Criteria. MRI and clinical features are used to classify response as one of four categories that range from complete response to disease progression.
- Correlation of molecular profiles with tumor response [Up to 36 months]
Assessed using PMBCs and exosomes extracted from peripheral blood samples.
