Intraarterial Carboplatin Combinations for Glioblastoma
Trial Summary
What is the purpose of this trial?
The standard of care for glioblastoma (GBM) treatment involves maximal resection followed by concomitant radiotherapy and temozolomide. Progression-free survival (PFS) with this treatment is only 6.9 months and relapse is inevitable. At relapse, there is no consensus regarding the optimal therapeutic strategy. The rationale behind the fact that limited chemotherapy agents are available in the treatment of malignant gliomas is related to the blood-brain barrier (BBB), which impedes drug entry to the brain. Intraarterial (IA) chemotherapy allows to circumvent this. Using IA delivery of carboplatin, can produce responses in 70% of patients for a median PFS of 5 months. Median survival from study entry was 11 months, whereas the overall survival (OS) 23 months. How can the OS and PFS be improved? By combining chemotherapeutic agents with different mechanisms of action. Study design: In this phase II trial, treatment will be offered at relapse. Surgery will be performed for cytoreduction if it is warranted, followed with a combination IA carboplatin + IA Cealyx (liposomal doxorubicin) or IA carboplatin + IA etoposide phosphate. Toxicity will be assessed according to the NCIC common toxicity criteria. Treatment will consist in either IA carboplatin (400 mg/m\^2) + IA Cealyx (30 mg/m\^2) or IA carboplatin (400 mg/m\^2) + IA etoposide phosphate (400 mg/m\^2) every 4-6 weeks (1 cycle). Up to twelve cycles will be offered. Outcome measurements: Tumor response will be evaluated using the RANO criteria by magnetic resonance imaging monthly. Primary outcome will PFS and tumor response. Secondary outcome will include median OS, toxicity, quality of life (QOL), neurocognition (NC). Putting together these data will allow to correlate clinical and radiological response to QOL and NC.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What data supports the effectiveness of the drug combination used in the clinical trial for glioblastoma?
Research shows that pegylated liposomal doxorubicin (Caelyx) can penetrate the blood-brain barrier better than standard doxorubicin, making it more effective for treating high-grade gliomas, a type of brain tumor. Additionally, combining Caelyx with carboplatin has shown promising activity in treating various solid tumors.12345
Is intraarterial carboplatin with pegylated liposomal doxorubicin safe for humans?
How does intraarterial carboplatin differ from other glioblastoma treatments?
Intraarterial carboplatin is unique because it is delivered directly into the arteries supplying the brain, which can increase drug concentration in the tumor and reduce systemic side effects compared to traditional intravenous methods. This approach may enhance the effectiveness of the drug while minimizing toxicity, making it a promising option for treating glioblastoma.19101112
