The number of observed Dose Limiting Toxicity (DLTs)

Time frame: 10 weeks

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.

The number of observed Dose Limiting Toxicity (DLTs)

Time frame: The duration of treatment for each patient, minimum of 34 weeks

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.

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
