Phase I/II Study of the Tolerability, Safety, and Efficacy of Liposomal Curcumin in Combination With Radiation and Temozolomide in Patients With Newly Diagnosed High-Grade Gliomas
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).
Detailed description
This study is a Phase Ib-IIa, 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 (XRT), and TMZ and adjuvant TMZ in newly diagnosed High-Grade Gliomas. The secondary objectives are to estimate the safety and tolerability of LC in combination with standard XRT and TMZ and adjuvant TMZ, to determine the feasibility of treatment during first 10 week. 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: up to 24 in Study Part 1 and up to 6 in Study Part 2. All patients will be treated with open-label intravenous (IV) LC on a weekly basis for a minimum of 34 infusions which begins following healing of glioma resection and at the approximate time of the initiation of SOC XRT and TMZ therapy. Patients will have LC therapy discontinued when there is either evidence of a) disease progression, b) safety concerns leading to discontinuation, or c) the patient requests to terminate LC therapy. LC weekly treatment will be continued following 34 weeks of treatment depending on patient's desires. Regular phone (or clinic) follow-up follows cessation of LC treatment (if stopped) to capture patient data on OS and PFS.

Outcome measures
Primary
The number of observed Dose Limiting Toxicity (DLTs)
The MTD/RP2D of LC in combination with XRT 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.
Time frame: 10 weeks
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.
Time frame: The duration of treatment for each patient, minimum of 34 weeks
Secondary
The incidence of Adverse Events
Time frame: The duration of treatment for each patient, minimum of 34 weeks
The proportion of patients at each dose level who receive at least 80% of the planned infusions of LC, 80% of XRT, and 60% of TMZ during the first 10 weeks of treatment
Time frame: 10 weeks
Overall Survival (OS)
Time frame: The duration of treatment for each patient, minimum of 34 weeks; OS is time from beginning of therapy to time of death.
Progression free survival (PFS)
Time frame: The duration of treatment for each patient, minimum of 34 weeks; PFS is time from the start of therapy until the date when tumor progression is documented
