What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines a new treatment called [177Lu]Lu-NeoB, a targeted radiotherapy, for glioblastoma, a type of brain cancer. The study aims to determine the optimal dose and assess its safety and effectiveness when combined with standard treatments like radiotherapy and temozolomide for newly diagnosed cases, or when used alone for recurrent cases. Additionally, it will evaluate the effectiveness of a new imaging agent in highlighting the tumor. Individuals recently diagnosed with glioblastoma or those with recurrent cases who have received standard treatments might be suitable for this trial. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new therapy.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it mentions that if you are on corticosteroids like dexamethasone, you must be on a stable dose of 4 mg/day or less for at least 7 days before starting the study treatment. Also, if you are taking medications that affect the heart's QT interval, you may need to stop or replace them with safer alternatives.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown that [177Lu]Lu-NeoB is generally well-tolerated, but concerns exist about its effects on the kidneys. Earlier research suggests that multiple doses might harm the kidneys. However, this information comes from earlier studies, and more data from current trials will help clarify these safety concerns. Prospective participants should discuss these potential risks with their doctor. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike the standard treatments for glioblastoma, which often include surgery, radiation, and chemotherapy, [177Lu]Lu-NeoB uses a novel approach known as targeted radioligand therapy. This treatment involves a radioactive substance, [177Lu]Lu, that specifically targets tumor cells, potentially increasing the precision of radiation delivery and sparing healthy tissue. Researchers are excited because this method might offer more effective targeting of cancer cells, reducing side effects and possibly improving outcomes for patients with both newly diagnosed and recurrent glioblastoma.

What evidence suggests that this trial's treatments could be effective for glioblastoma?

Research has shown that treatments using lutetium-177, such as [177Lu]Lu-NeoB, effectively treat various cancers. For example, a similar treatment, [177Lu]Lu-DOTATATE, produced positive results in glioma patients, with some experiencing tumor size reduction. This trial will evaluate [177Lu]Lu-NeoB in two treatment arms: one combining it with radiotherapy and Temozolomide for newly diagnosed glioblastoma, and another using it as a single agent for recurrent glioblastoma. Additionally, lutetium-177 is already used to diagnose and treat other cancers, including prostate and stomach cancer. These findings suggest that [177Lu]Lu-NeoB could be effective for glioblastoma patients. ^{2 4 6 7 8}

In a phase IIa trial involving 21 children with high-risk neuroblastoma, the treatment with 177-lutetium DOTATATE (LuDO) showed no objective responses after four courses, leading to the conclusion that this treatment schedule is not recommended for this condition.

Despite the lack of objective responses, the treatment did not result in significant toxicities, indicating that while LuDO may not be effective as a single agent, it could still have potential value in different treatment contexts or schedules.
