What is the purpose of this trial?

This trial aims to test whether adding Niacin CRT (a form of Vitamin B3) to the usual treatment for glioblastoma (an aggressive brain cancer) can improve outcomes. The researchers will first determine the safest dose of Niacin CRT and then evaluate its effectiveness when combined with standard treatments like radiation and Temozolomide (a chemotherapy drug). Individuals with a new diagnosis of IDH wild-type glioblastoma, who have not received prior treatments, might be suitable candidates. As a Phase 1/Phase 2 trial, this research focuses on understanding how the treatment works in people and measuring its effectiveness in an initial group, offering participants a chance to contribute to groundbreaking research.

Will I have to stop taking my current medications?

The trial requires that patients stop taking HMG-COA reductase inhibitors (a type of cholesterol-lowering medication) at least 2 weeks before starting Niacin CRT™. For other medications, the protocol does not specify, so it's best to discuss with the trial team.

Is there any evidence suggesting that Niacin CRT is likely to be safe for humans?

Research has shown that niacin, also known as vitamin B3, produced promising results in early studies. In experiments with mice, niacin helped immune cells shrink brain tumors and improve survival rates. These findings suggest that niacin might help treat glioblastoma, a type of brain cancer.

Regarding safety, people often use niacin as a vitamin supplement, and it is generally safe. However, specific safety information for using Niacin CRT in glioblastoma patients is still being collected. Since this trial is in its early stages, researchers are carefully monitoring for any side effects to determine the safest dose.

In summary, while niacin is usually safe, this trial aims to confirm its safety and effectiveness for treating glioblastoma. Researchers will closely monitor participants for any negative effects during the study. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for glioblastoma?

Unlike the standard treatment options for glioblastoma, which often include radiation and temozolomide, Niacin CRT introduces a unique controlled release technology. This approach involves starting Niacin CRT seven days before traditional chemo-radiation therapy, potentially enhancing the effectiveness of the treatment. Researchers are excited about Niacin CRT because it could improve how well patients tolerate the treatment and might boost the overall impact of the concurrent therapies. By integrating this controlled release mechanism, there's hope it will improve patient outcomes and provide a new avenue for tackling this aggressive form of brain cancer.

What evidence suggests that Niacin CRT might be an effective treatment for glioblastoma?

Research has shown that niacin, or vitamin B3, can help the immune system combat glioblastoma, a type of brain cancer. In studies with mice, niacin shrank tumors and extended their lifespan. It activates certain immune cells to attack the tumor and prevents the cancer from spreading. In this trial, participants will receive Niacin CRT alongside temozolomide, a common brain cancer drug, and radiation therapy. Some studies suggest that this combination can improve survival rates. These early findings offer hope that niacin could be a potential treatment for glioblastoma. ^{1 2 3 4 6}

What Are the Treatments Tested in This Trial?

Interventions

• Niacin CRT

Trial Overview The study tests the safety and maximum dose (Phase I) and effectiveness (Phase II) of Niacin CRT added to the Stupp protocol (standard radiation therapy plus Temozolomide chemotherapy), in treating newly diagnosed glioblastoma without IDH mutation.

How Is the Trial Designed?

Group I: Niacin Experimental Treatment 1 Intervention

Niacin controlled release technology (CRT): Niacin CRT™ is to be started 7 days before concurrent Radiation Therapy (RT)- Temozolomide (TMZ) treatment. Chemo/Radiation Therapy: For all patients, regardless of the phase of the study, concurrent RT and TMZ for 6 weeks followed by 6-12 cycles of monthly TMZ will be given. Concurrent Temozolomide: TMZ will be administered from the first to the last day of RT at 75 mg/m2 orally (PO) for a maximum of 49 days. Monthly Temozolomide: Cycles of chemotherapy Day 1 to Day 5 every 28 days will start 28 days (+/- 2 days) after the end of RT-TMZ. First cycle of TMZ is administered at 150 mg/m2 Day 1-Day 5 by mouth (PO) and increased to 200 mg/m2 Day 1-Day 5 PO from cycle 2 onwards if well tolerated. While 6 cycles are standard of care, the Neuro-Oncologist may continue up to 12 cycles if clinically appropriate.

Published Research Related to This Trial

Niacin (vitamin B3) has been identified as a potential treatment for glioblastomas by reactivating monocytes and macrophages, which can help reduce the growth of brain tumor-initiating cells (BTICs).

In mouse models, niacin treatment not only increased the presence of immune cells in tumors and reduced tumor size but also prolonged survival, especially when combined with the chemotherapy drug temozolomide.

Nicotinic acid (NA) has been shown to effectively inhibit the invasion of malignant glioma cells both in laboratory settings and in a rat model, suggesting its potential as a therapeutic option.

The mechanism of action involves upregulating E-cadherin, which enhances cell adhesion and reduces the invasive properties of glioma cells by promoting the degradation of the repressive transcription factor Snail1.

Extended-release niacin/laropiprant (ERN/LRPT) demonstrated a favorable safety profile, with fewer flushing-related side effects compared to traditional niacin (ERN-NSP), based on data from 4747 participants across multiple studies lasting up to 52 weeks.

While there were slight increases in liver enzymes with ERN/LRPT, these were reversible and not linked to liver damage, indicating that ERN/LRPT can be safely used to enhance the lipid-modifying effects of niacin without significant adverse effects on muscle or liver health.

Pyridoxine (vitamin B6) supplementation significantly decreases the viability of human glioblastoma cells (U-87 MG) in a dose- and time-dependent manner, likely by promoting apoptosis through increased active caspase 3 expression.

Cobalamin (vitamin B12) does not have the same cytotoxic effect as pyridoxine and can inhibit the cytotoxicity of pyridoxine when both are combined, suggesting a complex interaction that may influence treatment strategies for glioblastoma.
