Clinical Trial Summary

The objective of this study is to assess the tolerability, safety, and efficacy of Liposomal Curcumin (LC) in combination with radiotherapy (RT) and Temozolomide (TMZ) in patients with newly diagnosed High-Grade Gliomas (HGG).

Description:

This study is a Phase 1/2, single-center, single-institution, open-label, dose-escalation study in patients with newly diagnosed high-grade malignant gliomas. Dose finding will be performed using a time-to-event Bayesian optimal interval (TITE-BOIN) rule-based schema. The primary objectives of the study are to determine the maximum tolerated dose /recommended phase 2 dose of Liposomal Curcumin (LC) in combination with radiotherapy (RT), and TMZ and adjuvant TMZ in newly diagnosed High-Grade Gliomas, and to determine the safety and tolerability of LC IV infused over 3-hours. The secondary objectives are to estimate the safety and tolerability of LC in combination with standard RT and TMZ and adjuvant TMZ, to determine the feasibility of weekly LC infusion, defined as the number of patients being able to complete 80% of the planned doses of LC, 80% of RT, and 60% of TMZ within the first 10 weeks of treatment, and to assess efficacy as defined by overall survival (OS) and progression free survival (PFS) observed for each dose level. This study is an unblinded, sequential treatment intervention employing 3 dose levels. Approximately 50 patients will be screened to achieve up to 30 patients assigned to study intervention. The duration of treatment for each patient will be up to 34 weeks. Treatment starts with the beginning of infusion and ends, if tolerated, at the end of Cycle 6 of adjuvant TMZ.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The number of observed Dose Limiting Toxicity (DLTs)	The MTD/RP2D of LC in combination with RT and TMZ and adjuvant TMZ in newly diagnosed HGG will be determined by recording the number of observed dose limiting toxicities (DLTs). DLTs, as defined in this study occur if in the first three patients entered at a dose-level, more than one of these 3 experiences a serious adverse event, as defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5. If one of the first three patients entered at the level experiences an SAE (as defined by NCI CTCAE Version 5), then three additional patients are entered at that same dose level. If one of the additional three patients experiences an SAE (as defined by NCI CTCAE Version 5), the dose is not advanced beyond that level.	10 weeks
Primary	The number of observed Dose Limiting Toxicity (DLTs)	The safety and tolerability of LC infused IV over 3 hours will be assessed by recording the number of observed DLTs. DLTs, as defined in this study occur if in the first three patients entered at a dose-level, more than one of these 3 experiences a serious adverse event, as defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5. If one of the first three patients entered at the level experiences an SAE (as defined by NCI CTCAE Version 5), then three additional patients are entered at that same dose level. If one of the additional three patients experiences an SAE (as defined by NCI CTCAE Version 5), the dose is not advanced beyond that level.	The duration of treatment for each patient up to 34 weeks
Secondary	The incidence of Adverse Events	The safety and tolerability of LC in combination with standard RT/TMZ and adjuvant TMZ will be assessed by recording the incidence of Adverse Events (AEs) using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.; Subjects will undergo medical history evaluations, physical and neurological examinations, brain MRI, functional assessment using the Karnofsky Performance Scale (KPS) Index, vital sign measurements, weight, adverse event assessments, concomitant medication assessments, and laboratory testing including but not limited to blood sample collection for hematology and chemistry, urinalysis, coagulation, lipid panel, electrocardiogram, and pregnancy test for females of childbearing potential.	The duration of treatment for each patient, up to 34 weeks
Secondary	The proportion of patients at each dose level who receive at least 80% of the planned infusions of LC, 80% of RT, and 60% of TMZ during the first 10 weeks of treatment	The feasibility of weekly LC infusion will be assessed by recording the proportion of patients at each dose level who are able to complete at least 80% of the planned infusions of LC, 80% of RT, and 60% of TMZ during the first 10 weeks of treatment.	10 weeks
Secondary	Overall Survival (OS)	The efficacy of weekly LC infusion will be assessed by recording overall survival (OS) at each dose level, defined as the duration of time from the start of treatment with LC to time of death.	The duration of treatment for each patient up to 34 weeks; OS is time from beginning of therapy to time of death.
Secondary	Progression free survival (PFS)	The efficacy of weekly LC infusion will be assessed by recording progression free survival (PFS) based on Response Assessment in Neuro-Oncology (RANO) criteria at each dose level, defined as defined as the duration of time from the start of treatment with LC to time of progression or death.	The duration of treatment for each patient up to 34 weeks; PFS is time from the start of therapy until the date when tumor progression is documented
