What side effects are associated with this type of intervention?

Common treatments for glioblastoma include surgery, radiation therapy, and chemotherapy. Side effects of these treatments can vary but often include fatigue, headaches, nausea, vomiting, and hair loss. Specifically, for MDM2 inhibitors like BI 907828, side effects may include gastrointestinal issues, hematologic toxicity, and potential impacts on liver function. Radiation therapy can also cause skin irritation, brain swelling, and cognitive changes. It is important for patients to discuss these potential side effects with their healthcare provider to manage them effectively.

What prior FDA approvals exist?

The FDA has approved several treatments for Glioblastoma, including temozolomide, an oral alkylating agent, and bevacizumab, a monoclonal antibody targeting vascular endothelial growth factor (VEGF). These treatments aim to inhibit tumor growth and angiogenesis. While specific FDA approvals for MDM2 inhibitors in Glioblastoma are not mentioned, ongoing research, such as the trial involving BI 907828, indicates a growing interest in targeting the MDM2 pathway to treat this aggressive brain tumor.

What other types of research exist?

Promising novel alternatives to BI 907828 for glioblastoma patients include: 1) Bevacizumab, an anti-VEGF antibody, which has shown efficacy in reducing tumor growth and improving symptoms. 2) Everolimus, an mTORC1 inhibitor, which has demonstrated potential in slowing tumor progression. 3) Dabrafenib plus trametinib, targeting BRAF V600E mutations, which has shown sustained tumor control in gliomas with this mutation. 4) Pembrolizumab, an immune checkpoint inhibitor, which has shown promise in enhancing the immune response against glioblastoma.

MDM2 Inhibitor

Brigimadlin + Radiation for Glioblastoma

Q: What is the mechanism of action of this treatment?

Glioblastoma treatments often target the rapid and uncontrolled cell growth characteristic of this aggressive brain tumor. MDM2 inhibitors like BI 907828 work by blocking the MDM2 protein, which normally inhibits the tumor suppressor p53. By inhibiting MDM2, p53 activity is restored, leading to increased tumor cell death. Radiation therapy damages the DNA of cancer cells, preventing them from dividing and causing them to die. Chemotherapy agents, such as temozolomide, work by alkylating/methylating DNA, which also leads to cell death. These treatments are crucial for Glioblastoma patients as they aim to control tumor growth, improve survival rates, and alleviate symptoms.

Summary

This trial tests BI 907828, a new drug for treating brain tumors. It targets adults with newly diagnosed glioblastoma. The drug works by blocking a protein that helps cancer cells grow. The study aims to see how well the drug is absorbed in the tumor and find the highest safe dose when combined with radiation therapy.

Who is the study for?

Adults with newly diagnosed glioblastoma, a type of brain tumor. Part 1 is for those awaiting surgery; Part 2 for post-surgery patients eligible for radiation therapy. Must be over 18, have good performance status (0 or 1), and stable health on certain medications. Excludes those with specific genetic mutations, prior systemic therapy/radiotherapy (except Phase 0 participants), poor kidney function, or incompatible implants.

What is being tested?

The study tests BI 907828 (Brigimadlin), an MDM2 inhibitor cancer drug. Part 1 assesses how the drug accumulates in the tumor after one dose before surgery. In Part 2, the highest tolerable dose is sought alongside standard radiation therapy over six weeks with regular visits and potential continuation if beneficial.

What are the potential side effects?

While not explicitly listed in the provided information, side effects may include typical reactions to cancer drugs such as nausea, fatigue, blood count changes and increased risk of infections due to immune system suppression.
