177Lu-PSMA-617 for Brain Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called 177Lu-PSMA-617 to determine its safety for individuals with IDH wild type glioma, a type of brain cancer. The treatment uses a special form of radiation therapy and aims to assist patients who have already undergone standard treatments like surgery and chemotherapy. Participants should have a confirmed diagnosis of IDH wild type glioma and have completed other standard therapies. 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.
Do I need to stop my current medications to join the trial?
The trial requires that you be on a dose of 4 mg or less of dexamethasone (a type of steroid) for 5 days before starting the treatment. Other than this, the protocol does not specify if you need to stop taking your current medications.
Is there any evidence suggesting that 177Lu-PSMA-617 is likely to be safe for humans?
Research has shown that 177Lu-PSMA-617 has been tested in various contexts. One study demonstrated a noticeable decrease in PSMA activity after three treatment cycles, indicating effective targeting of certain cells. Another study found that 15% of patients experienced serious blood-related side effects, though these were manageable and not common for all recipients.
Overall, evidence suggests that 177Lu-PSMA-617 can be effective, but potential side effects should be considered. This treatment remains in the early stages of testing for brain cancer, so its complete safety profile is not yet known.12345Why do researchers think this study treatment might be promising for brain cancer?
Researchers are excited about 177Lu-PSMA-617 for brain cancer because it introduces a novel approach to treatment by specifically targeting prostate-specific membrane antigen (PSMA), which is often present in brain tumors. Unlike traditional chemotherapy or radiation, which can affect healthy brain tissue, this treatment uses a radioactive compound to directly deliver radiation to cancer cells, potentially reducing side effects. The combination of 177Lu-PSMA-617 with imaging techniques like 68Ga-PSMA-PET scans allows for precise monitoring of the treatment's effectiveness, offering hope for better outcomes in managing brain cancer.
What evidence suggests that 177Lu-PSMA-617 might be an effective treatment for brain cancer?
Research has shown that 177Lu-PSMA-617 holds promise for treating certain cancers. One study found it significantly lowered prostate-specific antigen (PSA) levels in many prostate cancer patients. In this trial, researchers are investigating 177Lu-PSMA-617 for its potential to treat brain tumors by targeting a protein called PSMA, often present in these tumors. Most patients tolerate the treatment well, with side effects that are usually manageable. Although more research is needed for brain cancer, these early results are encouraging.13678

Trial Overview
The study is testing the safety of a radiopharmaceutical therapy called 177Lu-PSMA-617 in treating certain brain tumors. It includes Temozolomide treatment, imaging tests like 68Ga-PSMA-PET scans/MRI, and assessing patient quality of life through questionnaires.

Experimental Treatment
Patients will begin the first and second cycles of adjuvant Temozolomide (TMZ) the night before the first and second infusions of 177Lu-PSMA-617, respectively. Post-treatment, MRI of the brain will be obtained every 2 months, as per standard of care. A 68Ga-PSMA-PET scan will be performed with the MRI of the brain 1 month after the second cycle of 177Lu-PSMA-617 and again at evidence of disease progression.
