Trial Summary

What is the purpose of this trial?

To find the best dose of ADI-PEG20 that can be given in combination with carboplatin and cabazitaxel to patients with AVPC.

Do I need to stop my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, it does exclude patients who have not recovered from adverse events of previous treatments to a certain level, and those with unresolved toxicity from previous therapies. It's best to discuss your specific medications with the trial investigators.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, it does mention that patients should not have unresolved side effects from previous treatments, except for certain prostate cancer therapies and bone-strengthening medications.

What data supports the idea that ADI-PEG 20 + Chemotherapy for Prostate Cancer is an effective treatment?

The available research does not provide specific data on the effectiveness of ADI-PEG 20 + Chemotherapy for Prostate Cancer. The studies mentioned focus on other treatments and drugs for prostate cancer, such as sipuleucel-T, radium-223, and siltuximab, but do not include information on ADI-PEG 20. Therefore, there is no direct evidence from the provided research to support the effectiveness of ADI-PEG 20 + Chemotherapy for Prostate Cancer. ^{1 2 3 4 5}

What safety data exists for ADI-PEG 20 + chemotherapy in prostate cancer?

The provided research does not contain specific safety data for ADI-PEG 20 combined with chemotherapy in prostate cancer. However, it includes safety data for amivantamab (Rybrevant) in non-small cell lung cancer (NSCLC) with EGFR exon 20 insertions, showing its safety and antitumor activity when combined with chemotherapy. Additionally, a phase 1 study of ADI-PEG 20 in mesothelioma evaluated its safety in combination with pemetrexed and cisplatin, but not specifically for prostate cancer. ^{6 7 8 9 10}

What safety data exists for ADI-PEG 20 and Amivantamab in humans?

Amivantamab has been shown to be safe in humans when used with chemotherapy for treating advanced non-small-cell lung cancer. ADI-PEG 20 has been evaluated for safety in a study with mesothelioma patients, showing it can be safely combined with chemotherapy. ^{6 7 8 9 10}

Is the drug Amivantamab, Tepotinib a promising treatment for prostate cancer?

The information provided does not mention Amivantamab or Tepotinib as treatments for prostate cancer, so we cannot determine if they are promising for this condition based on the given data. ^{3 11 12 13 14}

What makes the drug combination of ADI-PEG 20, Amivantamab, and Tepotinib unique for prostate cancer treatment?

The combination of ADI-PEG 20, Amivantamab, and Tepotinib is unique because it targets specific pathways involved in cancer growth and spread, potentially offering a novel approach compared to traditional chemotherapy. Amivantamab and Tepotinib are known for their roles in targeting specific proteins involved in cancer cell signaling, which may provide a more targeted treatment option for prostate cancer. ^{3 11 12 13 14}
